Useful information

This Operator's Manual describes all

models and all standard and optional

equipment of your vehicle available at the

time of publication of the Operator's

Manual. Country-specific differences are

possible. Please note that your vehicle may

not be equipped with all features

described. This also applies to safety-

related systems and functions.

Read the information on qualified

specialist workshops: (Y page 25).

Notes on breaking-in anew vehicle

Important safety notes

New and replaced brake pads and discs only

reach their optimum braking effect after

several hundred kilometers of driving.

Compensate for this by applying greater force

to the brake pedal.

The first 1,000miles (1,500 km)

The more you look after the engine when it is

new, the more satisfied you will be with its

performance in the future.

You should therefore drive at varying

vehicle and engine speeds for the first

1,000 miles (1,500 km).

Ideally, for the first 1,000 miles (1,500 km),

drive in program E (for AMG vehicles drive

program C).

Avoid heavy loads, e.g.driving at full

throttle, during this period.

Change gearingood time, before the

tachometer needle is Ô of the way to the

red area of the tachometer.

Do not manually shift to a lower gear to

brake the vehicle.

If possible, do not depress the accelerator

pedal past the point of resistance

(kickdown).

Only select shift ranges 3, 2 or 1 when

driving slowly, e.g. in mountainous terrain.

After 1,000 miles (1,500 km), you can

increase the engine speed gradually and

accelerate the vehicle to full speed.

Additional breaking-in notes for AMG

vehicles:

Do not drive faster than 85 mph

(140 km/h) for the first 1000 miles

(1500 km).

Only allow the engine to reach a maximum

engine speed of 4,500 rpm briefly.

Change gear in good time.

You should also observe these notes on

breaking in if the engine or parts of the drive

train on your vehicle have been replaced.

Always observe the respective speed

limits.

AMG vehicles with self-locking rear

axle differential

Your vehicle is equipped with aself-locking

differential on the rear axle. Change the oil

after a breaking-in period of 2,000 miles

(3,000 km) to improve protection of the rear

axle differential. This oil change prolongs the

service life of the differential. Have the oil

change carried out at a qualified specialist

workshop.

Driving

Important safety notes

WARNING

Objects in the driver's footwell can restrict the

pedal travel or obstruct adepressed pedal.

The operating and road safety of the vehicle

is jeopardized. There is a risk of an accident.

shoes with high heels

slippers

There is a risk of an accident.

Wear suitable footwear to ensure correct

usage of the pedals.

WARNING

If you switch off the ignition while driving,

safety-relevant functions are only available

with limitations, or not at all. This could affect,

for example, the power steering and the brake

boosting effect.You will require considerably

more effort to steer and brake. There is a risk

of an accident.

WARNING

If the parking brake has not been fully

released when driving, the parking brake can:

overheat and cause a fire

lose its hold function.

There is a risk of fire and an accident.Release

the parking brake fully before driving off.

Warm up the engine quickly. Do not use

the engine's full performance until it has

reached operating temperature.

Only shift the automatic transmission to

the desired drive position when the vehicle

is stationary.

Where possible, avoid spinning the drive

wheels when pulling away on slippery

roads. You could otherwise damage the

drive train.

AMG vehicles: at low engine oil

temperatures below 68 ‡(+20 †), the

maximumengine speed is restricted in

drop down.

You can open the doors from the inside at

any time.

You can also deactivate the automatic

locking feature (Y page 211).

Upshifts take place at higher engine

speeds after a cold start. This helps the

catalytic converter to reach its operating

temperature more quickly.

Hill startassist

Hill start assist helps you when pulling away

forwards or in reverse on an uphill gradient.

It holds the vehicle for a short time after you

have removed your foot from the brake pedal.

This gives you enough time to move your foot

from the brake pedal to the accelerator pedal

and to depress it before the vehicle begins to

roll.

WARNING

After a short time, hill start assist will no

longer brake your vehicle and it could roll

away. There is a risk of an accident and injury.

Therefore, quickly move your foot from the

brake pedal to the accelerator pedal. Never

leave the vehicle when it is held by hill start

assist.

Shift ranges

Introduction

When the automatic transmission is in

position D, it is possible to restrict or

derestrictthe shift range (Y page 152).

The shift range selected is shown in the

multifunction display. The automatic

transmission shifts only as far as the selected

gear.

Shift range:

You can use the engine's braking

effect

You can use the braking effect of

the engine on downhill gradients

and for driving:

on steep mountain roads

in mountainous terrain

in arduous conditions

To use the braking effect of the

engine on extremely steep downhill

gradients and on long downhill

stretches

Restricting the shift range

Press the selector lever to the left towards

D–.

Pull the left-hand steering wheel paddle

shifter.

The automatic transmission shifts down

one gear and restricts the shift range to the

relevant gear.

If the engine exceeds the maximum

engine speed when shifting down, the

automatic transmission protects against

engine damage by not shifting down.

If the maximum engine speed for the shift

range is reached and you continue to

accelerate, the automatic transmission

shifts up, even if the shift range is

restricted. This prevents the engine from

overrevving.

Extending the shift range

Briefly press the selector lever to the right

towards D+.

Pull the right-hand steering wheel paddle

shifter.

The shift range is derestricted.

Clearing the shift range restriction

Press and hold the selector lever towards

D+ until D is shown once more in the

to accelerate, the automatic transmission

shifts up. If manual drive program M has

been selected, the automatic transmission

does not switch up.

Briefly press the selector lever to the right

towards D+.

Pull the right-hand steering wheel paddle

shifter (Y page 151).

The automatic transmission shifts up to the

next gear.

AMG vehicles

In manual drive program M, the automatic

transmission does not shift up

automatically even when the engine

limiting speed for the current gear is

reached. When the engine limiting speed is

reached, the fuel supply is cut to prevent

the engine from overrevving. Always make

sure that the engine speed does not reach

the red area of the tachometer. There is

otherwise a risk of engine damage.

Before the engine speed reaches the red area,

an upshift indicator appears in the

distracted from traffic conditions. You could

also lose control of the vehicle. There is a risk

of an accident.

Only operate this equipment when the vehicle

is stationary.

Observe the legal requirements for the

country in which you are driving. Some

jurisdictions prohibit the driver from using a

mobile phone while driving a vehicle.

If you make a call while driving, always use

hands-free mode. Only operate the telephone

when the traffic situation permits. If you are

unsure, pull over to a safe location and stop

before operating the telephone.

Bear in mind that at a speed of only 30 mph

(approximately 50 km/h), the vehicle covers

a distance of 44 feet (approximately 14 m)

per second.

Drive sensibly –save fuel

Observe the following tips to save fuel:

The tires should always be inflated to the

recommended tire pressure.

Remove unnecessary loads.

Remove roof racks whenthey are not

needed.

160

Driving tips

Driving and parking

Warm up the engine at low engine speeds.

Avoid frequent acceleration or braking.

Have all maintenance work carried out as

indicated by the service intervals in the

Maintenance Booklet or by the service

interval display.

Fuel consumption also increases when

driving in cold weather, in stop-start traffic

and in hilly terrain.

Drinking and driving

WARNING

Drinking and driving and/or taking drugs and

driving are very dangerous combinations.

Even a small amount of alcohol or drugs can

affect your reflexes, perceptions and

judgment.

The possibility of a serious or even fatal

accident are greatly increased when you drink

or take drugs and drive.

Do not drink or take drugs and drive or allow

anyone to drive who has been drinking or

taking drugs.

Emission control

WARNING

Combustion engines emit poisonous exhaust

gases such as carbon monoxide. Inhaling

these exhaust gases leads to poisoning.There

is a risk of fatal injury. Therefore never leave

the engine running in enclosed spaces

without sufficient ventilation.

Certain engine systems are designed to keep

the level of poisonous components in exhaust

fumes within legal limits.

These systems only work at peak efficiency if

they are serviced exactly in accordance with

the manufacturer's specifications. For this

reason, all work on the engine must be carried

out by qualified and authorized Mercedes-

Benz technicians.

The engine settings must not be changed

under any circumstances. Furthermore, all

specific service work must be carried out at

regular intervals and in accordance with the

Mercedes-Benzservice requirements. Details

can be found in the Maintenance Booklet.

ECO display

The ECO display gives you information on how

economical your driving style is. The ECO

display assists you in achieving the optimum

driving style in terms of consumption, taking

the actual and selected conditions into

consideration.Your driving style can

significantly influence the vehicle's

consumption.

Example: ECO display

The ECO display consists of three bars:

Acceleration

Constant

Coasting

The percent value is the average value of the

three bars. The three bars and the mean value

begin at the value of 50%. Ahigher

percentage indicates a moreeconomical

driving style.

The ECO display does not indicate the actual

fuel consumption and a fixed percentage

count in the ECO display does not indicate a

fixed consumption figure.

Apart from driving style, consumption is

dependent on many factors such as, e.g.:

load

tire pressure

cold start

choice of route

electrical consumers switched on

Driving tips

161

Driving and parking

These factors are not taken into

consideration by the ECO display.

The evaluation of your driving style is carried

out using the following three categories:

Acceleration (evaluation of all

acceleration processes):

The bar fills up: moderate acceleration,

especially at higher speeds

The bar empties: sporty acceleration

Constant

(assessment of driving behavior

at all times):

The bar fills up: constant speed and

avoidance of unnecessary acceleration

and deceleration

The bar empties: fluctuations in speed

Coasting (assessment of all deceleration

processes):

The bar fills up: anticipatory driving,

keeping your distance and early release

of the accelerator.The vehicle can coast

without use of the brakes.

The bar empties: frequent braking

The ECO display summaries the driving

characteristics from the start of the journey

to its completion. For this reason, the bars

change dynamically at the beginning of the

journey. On longer journeys, there are

fewer changes. For more dynamic changes,

carry out a manual reset.

Further information on the ECO display

Braking

Important safety notes

WARNING

If you shift down on a slippery road surface in

an attempt to increase the engine's braking

effect, the drive wheels could lose their grip.

There is an increased danger of skidding and

accidents.

Do not shift down for additional engine

braking on a slippery road surface.

Downhill gradients

On long and steep gradients, you must

reduce the load on the brakes by shifting

early to a lower gear. This allows you to take

advantage of the engine braking effect and

helps avoid overheating and excessive

wear of the brakes.

When you take advantage of the engine

braking effect, a drive wheel may not turn

for some time, e.g. on a slippery road

surface. This could cause damage to the

drive train. This type of damage is not

covered by the Mercedes-Benzwarranty.

Heavy and light loads

WARNING

If you restyour foot on the brake pedal while

driving, the braking system can overheat. This

increases the stopping distance and can even

cause the braking system to fail. There is a

risk of an accident.

Never use the brake pedal as a footrest.Never

depress the brake pedal and the accelerator

pedal at the same time.

Depressing the brake pedal constantly

results in excessive and premature wear to

the brake pads.

If the brakes have been subjected to a heavy

load, do not stop the vehicle immediately.

Drive on for a short while. This allows the

airflow to cool the brakes more quickly.

162

Driving tips

Driving and parking

Wet roads

If you have drivenfor a long time in heavy rain

without braking, there may be a delayed

reaction from the brakes when braking for the

first time. This may also occur after the

vehicle has been washed.

You have to depress the brake pedal more

firmly. Maintain a greater distance from the

vehicle in front.

After driving on a wet road or having the

vehicle washed, brake firmly while paying

attention to the traffic conditions. This will

warm up the brake discs, thereby drying them

more quickly and protecting them against

corrosion.

Limited braking performance on salt-

treated roads

If you drive on salted roads, a layer of salt

residue may form on the brake discs and

brake pads. This can result in a significantly

longer braking distance.

Brake occasionally to remove any possible

salt residue. Make sure that you do not

endanger other road users when doing so.

Carefully depress the brake pedal and the

beginning and end of a journey.

Maintain a greater distance to the vehicle

ahead.

Servicing the brakes

If the red brake warning lamp lights up in

the instrument cluster and you hear a

warning tone while the engine is running,

the brake fluid level may be too low.

Observe additional warning messages in

the multifunction display.

The brake fluid level may be too low due to

brake pad wear or leaking brake lines.

Have the brake system checked

immediately. This work should be carried

out at a qualified specialist workshop.

All checks and maintenance work on the

brake system must be carried out at a

qualified specialist workshop. Consult a

qualified specialist workshop to arrange this.

Have brake pads installed and brake fluid

replaced at a qualified specialist workshop.

Vehicles with 4MATIC: function or

performance tests may only be carried out

on a 2-axle dynamometer. If you are

planning to have the vehicle tested on such

a dynamometer, contact an authorized

Mercedes-Benz Center to obtain further

information first. Otherwise, you could

damage the drive train or the brake system.

Vehicles with 4MATIC: as the ESP

system operates automatically, the engine

and the ignition must be switched off

(SmartKey in position 0 or 1 in the ignition

lock or Start/Stop button in position 0 or

1) while the parking brake is being tested

If the brake system has only been subject to

moderate loads, you should test the

functionality of your brakes at regular

intervals. To do so, press firmly on the brake

pedal when driving at a high speed. This

improves the grip of the brake pads.

High-performance brake system for

AMG vehicles

The high-performance brake system is

installed only on the C 63 AMG.

The high-performance brake system is

designed for heavy loads. This may lead to

noise when braking. This will depend on:

Speed

Braking force

Environmental conditions,such as

temperature and humidity

The wear and tear on individual brake system

components, e.g. brake pads/linings or

discs, depends on:

the individual driving style

the operating conditions

Forthis reason, it is impossible to state a

mileage that will be valid under all

circumstances. An aggressive driving style

will lead to high wear. You can obtain further

information about this from your authorized

Mercedes-BenzCenter.

New and replaced brake pads and discs only

reach their optimum braking effect after

several hundred kilometers of driving.

Compensate for this by applying greater force

to the brake pedal. Keep this in mind, and

adapt your driving and braking accordingly

during this break-in period.

Excessive heavy braking results in

correspondingly high brake wear. Observe

the brake wear warning lamp in the

instrument cluster and note any brake status

messages in the multifunction display.

Especially for high performance driving, it is

important to maintain and have the brake

system checked regularly.

Driving on wet roads

Hydroplaning

If water has accumulated to a certain depth

on the road surface, there is a danger of

hydroplaning occurring, even if:

you drive at low speeds.

the tires have adequate tread depth.

For this reason, in the event of heavy rain or

in conditions in which hydroplaning may

occur, you must drive in the following

manner:

lower your speed.

avoid ruts.

brake carefully.

Driving on flooded roads

Do not drive through flooded areas.

Check the depth of any water before driving

through it. Drive slowly through standing

water. Otherwise, water may enter the

vehicle interior or the engine compartment.

This can damage the electronic

components in the engineorthe automatic

transmission. Water can also be drawn in

by the engine's air suction nozzles and this

can cause engine damage.

Slippery road surfaces

WARNING

If you shift down on a slippery road surface in

an attempt to increase the engine's braking

effect, the drive wheels could lose their grip.

There is an increased danger of skidding and

accidents.

Do not shift down for additional engine

braking on a slippery road surface.

Drive particularly carefully on slippery road

surfaces. Avoid sudden acceleration, steering

and braking maneuvers. Do not use the cruise

control or DISTRONIC PLUS.

If the vehicle threatens to skid or cannot be

stopped when moving at low speed:

Shift the transmission to position N.

For more information on driving with

snow chains, see (Y page 313).

The outside temperature indicator is not

designed to serve as an ice-warning device

and is therefore unsuitable for that purpose.

Changes in the outside temperature are

displayed after a short delay.

Indicated temperatures just above the

freezing point do not guarantee that the road

surface is free of ice. The road may still be icy,

especially in wooded areas or on bridges. The

vehicle could skid if you fail to adaptyour

driving style. Always adapt your driving style

and drive at a speed to suit the prevailing

weather conditions.

You should pay special attention to road

conditions when temperatures are around

freezing point.

Driving systems

Cruise Control

Important safety notes

Cruise control maintains a constant road

speed for you. It brakes automatically in order

to avoid exceeding the set speed. On long and

steep downhill gradients, especially if the

vehicle is laden, you must select shift range

1, 2 or 3 in good time. By doing so, you will

make use of the braking effect of the engine.

This relieves the load on the brake system and

prevents the brakes from overheating and

wearing too quickly.

Use cruise control only if road and traffic

conditions make it appropriate to maintain a

steady speed for a prolonged period. You can

Driving systems

165

Driving and parking

store any road speed above 20 mph

(30 km/h).

If you fail to adaptyour driving style, cruise

control can neither reduce the risk of an

accident nor override the laws of physics.

Cruise control cannot take into account the

road, traffic and weather conditions. Cruise

control is only an aid. You are responsible for

the distance to the vehicle in front, for vehicle

speed, for braking in good time and for

staying in your lane.

Do not use cruise control:

in road and traffic conditions which do not

allow you to maintain a constant speed e.g.

in heavy traffic or on winding roads

on slippery road surfaces. Braking or

accelerating could cause the drive wheels

to lose traction and the vehicle could then

skid

when there is poor visibility, e.g. due to fog,

heavy rain or snow

If there is a change of drivers, advise the new

driver of the speed stored.

stored speed on downhill gradients by

automatically applying the brakes.

Storing the current speed or calling up

the last stored speed

WARNING

If you call up the stored speed and it differs

from the current speed, the vehicle

accelerates or decelerates. If you do not know

the stored speed, the vehicle could accelerate

DISTRONIC PLUS

Important safety notes

DISTRONIC PLUS regulates the speed and

automatically helps you maintain the

distance to the vehicle detected in front.

DISTRONIC PLUS brakes automatically so

that the set speed is not exceeded.

On long and steep downhill gradients,

especially if the vehicle is laden, you must

select shift range 1, 2 or 3 in good time. By

doing so, you will make use of the braking

effect of the engine. This relieves the load on

the brake system and prevents the brakes

from overheating and wearing too quickly.

If DISTRONIC PLUS detects a slower-moving

vehicle in front, your vehicle is braked in order

to maintain the preset distance to the vehicle

in front.

WARNING

DISTRONIC PLUS does not react to:

people or animals

stationary obstacles on the road, e.g.

stopped or parked vehicles

oncoming and crossingtraffic

As a result, DISTRONIC PLUS may neither give

warnings nor intervene in such situations.

There is a risk of an accident.

Always pay careful attention to the traffic

situation and be ready to brake.

WARNING

DISTRONIC PLUS cannot always clearly

identify other road users and complextraffic

braking force is insufficient, DISTRONIC PLUS

warns you visually and audibly.There is a risk

of an accident.

In such cases, apply the brakes yourself and

try to take evasive action.

If DISTRONIC PLUS or the HOLD function

is activated, the vehicle brakes

automatically in certain situations. To

prevent damage to the vehicle, deactivate

DISTRONIC PLUS and the HOLD function in

the following or other similar situations:

when towing the vehicle

in the car wash

If you fail to adapt your driving style,

DISTRONIC PLUS can neither reduce the risk

of accident nor override the laws of physics.

DISTRONIC PLUS cannot take into account

the road, traffic and weather conditions.

DISTRONIC PLUS is only an aid. You are

responsible for the distance to the vehicle in

front, for vehicle speed, for braking in good

time and for staying in your lane.

Do not use DISTRONIC PLUS:

in road and traffic conditions which do not

allow you to maintain a constant speed e.g.

in heavy traffic or on winding roads

on slippery road surfaces. Braking or

accelerating could cause the drive wheels

to lose traction and the vehicle could then

skid

when there is poor visibility, e.g. due to fog,

heavy rain or snow

DISTRONIC PLUS may not detect narrow

vehicles driving in front, e.g. motorcycles, or

vehicles driving on a different line.

In particular, the detection of obstacles can

be impaired if:

dirt on the sensors or anything else

covering the sensors

snow or heavy rain

interference by other radar sources

strong radar reflections, for example, in

parking garages

If DISTRONIC PLUS no longer detects a

vehicle in front, DISTRONIC PLUS may

unexpectedly accelerate the vehicle to the

stored speed.

This speed may:

be too high if you are driving in a filter lane

or an exit lane

be so high when driving in the right-hand

lane that you overtake vehicles in the left-

hand lane

be so high when driving in the left-hand lane

that you overtake vehicles in the right-hand

lane

If there is a change of drivers, advise the new

driver of the speed stored.

For DISTRONIC PLUS to assist you when

driving, the radar sensor system must be:

activated (Y page 211)

operational

If there is no vehicle in front, DISTRONIC

PLUS operates in the same way as cruise

control in the speed range between 20 mph

(Canada: 30 km/h) and 120 mph (Canada:

200 km/h). If a vehicle is driving in front of

you, it operates in the speed range between

0 mph (0 km/h) and 120 mph (Canada:

200 km/h).

Do not use DISTRONIC PLUS while driving on

roads with steep gradients.

If the vehicle in front of you is stationary, you

can only activate DISTRONIC PLUS once your

vehicle is stationary as well.

Briefly pull the cruise control lever towards

you ?, or press it up : or down ;.

DISTRONIC PLUS is selected.

DISTRONIC PLUS can only be activated at

under 20 mph (30 km/h) if avehicle in front

has been detected. Therefore, the

DISTRONIC PLUS distance display in the

your foot from the brake pedal.

Briefly pull the cruise control lever towards

you ?.

Accelerate briefly.

Your vehicle pulls away and adapts its

speed to that of the vehicle in front.

Driving

If there is no vehicle in front, DISTRONIC

PLUS operates in the same way as cruise

control.

If DISTRONIC PLUS detects that the vehicle

in fronthas slowed down, it brakes your

vehicle.Inthis way, the distance you have

selected is maintained.

If DISTRONIC PLUS detects that the vehicle

in front is driving faster, it accelerates your

vehicle, but only up to the speed you have

stored.

Changing lanes

If you change to the passing lane, DISTRONIC

PLUS supports you when:

you are driving faster than 40 mph

(60 km/h)

DISTRONIC PLUS is maintaining the

distance to a vehicle in front

you switch on the appropriate turn signal

DISTRONIC PLUS does not detect a danger

of collision

If these conditions are fulfilled, your vehicle

is accelerated. Acceleration will be

interrupted if changing lanes takes too long

or if the distance between your vehicle and

the vehicle in front becomes too small.

When changing lanes, DISTRONIC PLUS

monitors the left lane on left-hand drive

vehicles and the right lane on right-hand

drive vehicles.

(Y page 173).

If DISTRONIC PLUS detects that the vehicle

in front is stopping, it brakes your vehicle until

it is stationary.

Once your vehicle is stationary, it remains

stationary and you do not need to depress the

brake.

Depending on the specified minimum

distance, your vehicle will come to a

standstill at a sufficient distance behind the

vehicle in front.The specified minimum

distance is set using the control on the

cruise control lever.

You will see a warning message in the

Tips for driving with DISTRONIC PLUS

General notes

The following contains descriptions of certain

road and traffic conditions in which you must

be particularly attentive. In such situations,

brake if necessary. DISTRONIC PLUS is then

deactivated.

Cornering, going into and coming out of a

bend

The ability of DISTRONIC PLUS to detect

vehicles when cornering is limited. Your

vehicle may brake unexpectedly or late.

Vehicles traveling on adifferent line

DISTRONIC PLUS may not detect vehicles

traveling on a different line. The distance to

the vehicle in frontwill be too short.

Other vehicles changing lanes

174

Driving systems

Driving and parking

DISTRONIC PLUS has not detected the

vehicle cutting in yet. The distance to this

vehicle will be too short.

Narrow vehicles

DISTRONIC PLUS has not yet detected the

vehicle in front on the edge of the road,

because of its narrow width.The distance to

the vehicle in front will be too short.

Obstructions and stationary vehicles

DISTRONIC PLUS does not brake for

obstacles or stationary vehicles. If, for

example, the detected vehicle turns a corner

and reveals an obstacle or stationary vehicle,

DISTRONIC PLUS will not brake for these.

Crossing vehicles

DISTRONIC PLUS may mistakenly detect

vehicles that are crossing your lane.

Activating DISTRONIC PLUS at traffic lights

with crossing traffic, for example, could cause

your vehicle to pull away unintentionally.

4MATIC (permanent four-wheel drive)

If you fail to adapt your driving style, 4MATIC

can neither reduce the risk of accident nor

override the laws of physics. 4MATIC cannot

take account of road, weather and traffic

conditions. 4MATIC is only an aid. You are

responsible for the distance to the vehicle in

front, for vehicle speed, for braking in good

time and for staying in your lane.

If a drive wheel spins due to insufficient grip:

Only depress the acceleratorpedal as far

as necessary when pulling away.

Accelerate less when driving.

Never tow the vehicle with one axle

raised. This may damage the transfer case.

Damage of this sort is not covered by the

Mercedes-Benz Limited Warranty. All

wheels must remain either on the ground

or be fully raised. Observe the instructions

for towing the vehicle with all wheels in full

contact with the ground.

4MATIC ensures that all four wheels are

permanently driven. Together with ESP

, it

improves the traction of your vehicle

whenever a drive wheel spins due to

insufficient grip.

In wintry driving conditions, the maximum

effect of 4MATIC can only be achieved if

you use winter tires (M+S tires), with snow

chains if necessary.

PARKTRONIC

Important safety notes

PARKTRONIC is an electronic parking aid with

ultrasonicsensors. It indicates visually and

audibly the distance between your vehicle

and an object.

PARKTRONIC is only an aid. It is not a

replacement for your attention to your

immediate surroundings. You are always

responsible for safe maneuvering, parking

and exiting a parking space. When

maneuvering, parking or pulling out of a

parking space, make sure that there are no

persons, animals or objects in the area in

which you are maneuvering.

When parking, pay particular attention to

objects above or below the sensors, such

as flower pots or trailer drawbars.

PARKTRONIC does not detectsuch objects

when they are in the immediate vicinity of

the vehicle. You could damagethe vehicle

or the objects.

The sensors may not detect snow and other

objects that absorb ultrasonic waves.

Ultrasonic sources such as an automatic

car wash, the compressed-air brakes on a

truck or a pneumatic drill could cause

PARKTRONIC to malfunction.

PARKTRONIC may not function correctly on

uneven terrain.

PARKTRONIC is activated automatically when

you:

switch on the ignition

shift the transmission to position D, R or N

release the parking brake

PARKTRONIC is deactivated at speeds above

11 mph (18 km/h). It is reactivated at lower

speeds.

PARKTRONIC monitors the area around your

vehicle using six sensors in the front and four

sensors in the rear.

Asuitable parking space is indicated by the

parking symbol. You receive steering

instructions when parking.You may also use

PARKTRONIC (Y page 179).

Parking Guidance is only an aid. It is not a

replacement for your attention to your

immediate surroundings. You are always

responsible for safe maneuvering, parking

and exiting a parking space. When

maneuvering, parking or pulling out of a

parking space, make sure that there are no

persons, animals or objectsinthe area in

which you are maneuvering.

WARNING

If objects are located above the detection

range, Parking Guidance may provide steering

instructions too soon. You may cause a

collision as a result. There is a risk of an

accident.

If objects are located above the detection

range, stop and switch off Parking Assist.

Pay particular attention to low objects or

objects with flat surfaces, such as trailer

drawbars, posts, cross beams and curbs.

These types of objects cannot be detected

by Parking Guidance and may damage the

vehicle.

When PARKTRONIC is deactivated, Parking

Guidance is also unavailable.

Driving systems

Driving and parking

Use Parking Guidance for parking spaces:

that are parallel to the direction of travel

that are on straight roads, not bends

that are on the same level as the road, i.e.

not on the pavement, for example. Parking

Guidance may not detect flat curbs

Parking tips:

On narrow roads, drive as close to the

parking space as possible.

Parking spaces that are littered, overgrown

or partially occupied by trailer drawbars

might be identified incorrectly or not at all.

Snowfall or heavy rain may lead to a parking

space being measured inaccurately.

Pay attention to the PARKTRONIC

(Y page 180) warning messages during the

parking procedure.

When transporting a load which protrudes

from your vehicle, you must not use Parking

Guidance.

Never use Parking Guidance with snow

chains or an emergency spare wheel

mounted.

Make sure that the tire pressures are

always correct.This has adirecteffect on

the steering instructions.

The way yourvehicle is positioned in the

parking space after parkingis dependent

on various factors. These include the

position and shape of the vehicles parked

in front and behind it and the conditions of

the location. In some cases, Parking

Guidance may guide you too far or not far

enough into a parking space. In some

cases, it may also lead you across or onto

the curb. If necessary, cancel the parking

procedure with Parking Guidance.

If unavoidable, you should drive over

obstacles such as curbs slowly and not at

a sharp angle. Otherwise, you may damage

the wheels or tires.

driver.

Driving systems

185

Driving and parking

ATTENTION ASSIST helps you during long,

monotonous journeys, such as on highways.

It is active in the range between 50 mph

(80 km/h) and 112 mph (180 km/h).

If ATTENTION ASSIST detects typical

indicators of fatigue or increasing lapses in

concentration on the part of the driver, it

suggests you take a break.

ATTENTION ASSIST assesses your level of

fatigue or lapses in concentrationby taking

the following criteria into account:

your personal driving style, e.g. steering

characteristics

journey details, e.g. time of day and length

of journey

The functionality of ATTENTION ASSIST is

restricted and warnings may be delayed or

not occur at all:

if the road condition is poor, e.g. if the

surface is uneven or if there are potholes

if there is a strong side wind

if you have adopted a sporty driving style

with high cornering speeds or high rates of

acceleration

if you are predominantly driving slower

than 50 mph (80 km/h) or faster than

112 mph (180 km/h)

if you are currently using COMAND or

making a telephone call withit

if the time has been set incorrectly

in active driving situations, such as when

you change lanes or change your speed

Blind Spot Assist uses a radar sensor system

to monitor the areas on both sides of your

vehicle. It supports you from speeds of

approximately 20 mph (30 km/h). A warning

186

Driving systems

Driving and parking

display in the exterior mirrors draws your

attention to vehicles detected in the

monitored area. If you then switch on the

corresponding turn signal to change lanes,

you will also receive a visual and audible

collision warning.Blind Spot Assist uses

sensors in the rear bumper for monitoring

purposes.

For Blind Spot Assist to assist you when

driving, the radar sensor system must be:

activated(Y page 211)

operational

Important safety notes

Blind Spot Assist is only an aid. It may fail to

detect some vehicles and is no substitute for

attentive driving. Always ensure that there is

sufficientdistance to the side for other road

users and obstacles.

WARNING

Blind Spot Assist does not react to:

vehicles overtaken too closely on the side,

placing theminthe blind spot area

vehicles being overtaken at a speed

difference of more than 7.5 mph

(12 km/h)

vehicles which approach with a large speed

differential and overtake your vehicle

As a result, Blind Spot Assist may not give

warnings in such situations. There is a risk of

an accident.

Always observe the traffic conditions

carefully, and maintain a safe lateral distance.

USA only:

This device has been approved by the FCC

as a "VehicularRadar System". The radar

sensor is intended for use in an automotive

Monitoring range of the sensors

In particular, the detection of obstacles can

be impaired if:

dirt on the sensors or anything else

covering the sensors

poor visibility, e.g. due to fog, heavy rain,

snow or spray

narrow vehicles, e.g. motorcycles or

bicycles

the road has very wide lanes

the road has narrow lanes

you are not driving in the middle of the lane

there are barriers or similar lane borders

Vehicles in the monitoring range are then not

indicated.

Blind Spot Assist monitors the area up to

10 ft (3m) behind your vehicle and directly

nextto your vehicle, as shown in the diagram.

If the lanes are narrow, vehicles driving in the

lane beyond the lane next to your vehicle may

be indicated, especially if the vehicles are not

driving in the middle of their lane. This may

be the case if there are vehicles driving at the

inner edge of their lanes.

Warning vibration in the steering wheel

A warning may be given if a front wheel

passes over a lane marking. It will warn you

by means of intermittent vibration in the

steering wheel for up to 1.5 seconds.

In order that you are warned only when

necessary and in good time if you cross the

lane marking, the system recognizes certain

conditions and warns you accordingly.

The warning vibration occurs earlier if:

you approach the outer lane marking on a

bend.

the road has very wide lanes, e.g. a

highway.

the system recognizes solid lane markings.

The warning vibration occurs later if:

the road has narrow lanes.

you cut the corner on a bend.

Lane-correcting brake application

WARNING

A lane-correcting brake application cannot

always bring the vehicle back into the original

lane. There is a risk of an accident.

Always steer, brake or accelerate yourself,

especially if Active Lane Keeping Assist warns

you or makes a lane-correcting brake

application.

WARNING

Active Lane Keeping Assist does not detect

traffic conditions or road users. In very rare

cases, the system may make an inappropriate

brake application, e.g. after intentionally

driving over a solid lane marking. There is a

risk of an accident.

An inappropriate brake application may be

interrupted at any time if you steer slightly in

the opposite direction. Always make sure that

there is sufficient distance on the side for

other traffic or obstacles.

If you leave your lane, under certain

circumstances the vehicle will brake briefly

bringing the vehicle back to the original lane.

This function is available in the range between

40 mph and 120 mph (60 km/h and

200 km/h).

A lane-correcting brake application can only

be made after driving over a solid,

recognizable lane marking. Before this, a

warning must be given by means of

intermittent vibration in the steering wheel.

In addition, a lane with lane markings on both

sides must be recognized. The brake

application also slightly reduces vehicle

speed.

If a lane-correcting brake application occurs,

the following, for example, appears in the

multifunction display:

A further lane-correcting brake

application can only occur after your

vehicle has returned to the original lane.
