Operation

In the “Operation” section you will find

detailed information on operating, main-

taining and caring for your vehicle.

The first 1000 miles (1500 km)

The more cautiously you treat your vehicle

during the break-in period, the more satis-

fied you will be with its performance later

on.

앫 Drive your vehicle during the first

1000 miles (1500 km) at varying but

moderate vehicle and engine speeds.

앫 During this period, avoid heavy loads

(full throttle driving) and excessive

engine speeds (no more than

maximum rpm in each gear).

앫 Shift gears in a timely manner.

앫 Avoid accelerating by kick-down.

앫 Do not attempt to slow the vehicle

down by shifting to a lower gear using

the gear selector lever.

앫 Select positions 3, 2 or 1 only when

driving at moderate speeds (for hill

driving).

After 1000 miles (1500 km) you may

gradually increase vehicle and engine

speeds to the permissible maximum.

All of the above instructions, as may apply

to your vehicle type, also apply when

driving the first 1000 miles (1500 km)

after the engine or the rear differential has

been replaced

Additional instructions for AMG

vehicles:

앫 During the first 1000 miles

(1500 km), do not exceed a speed

of 85 mph (140 km/h).

앫 During this period, avoid engine

speeds above 4500 rpm in each

gear.

Always obey applicable speed limits.

Operation

Driving instructions

왔 Driving instructions

Drive sensibly – save fuel

Fuel consumption, to a great extent,

depends on driving habits and operating

conditions.

To save fuel you should:

앫 Keep tires at the recommended infla-

tion pressures.

앫 Remove unnecessary loads.

앫 Remove roof rack when not in use.

앫 Allow engine to warm up under low

load use.

앫 Avoid frequent acceleration and decel-

eration.

앫 Have all maintenance work performed

at the intervals specified in the

Maintenance Booklet and as required

by the maintenance service display.

Contact an authorized Mercedes-Benz

Center.

Fuel consumption is also increased by

driving in cold weather, in stop-and-go

traffic, on short trips and in hilly country.

Drinking and driving Pedals

Power assistance

Warning! G

Drinking and driving and/or taking drugs

and driving are very dangerous combina-

tions. Even a small amount of alcohol or

drugs can affect your reflexes, perceptions

and judgement.

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.

Warning! G

Keep driver’s foot area clear at all times.

Objects stored in this area may impair pedal

movement.

Warning! G

With the engine not running, there is no

power assistance for the brake and steering

systems. In this case, it is important to keep

in mind that a considerably higher degree of

effort is necessary to brake and steer the

vehicle.

266

Operation

Driving instructions

Brakes To help prevent brake disk corrosion after

driving on wet road surfaces (particularly

salted roads), it is advisable to brake the

vehicle with considerable force prior to

parking. The heat generated serves to dry

the brakes.

If your brake system is normally only

subject to moderate loads, you should

occasionally test the effectiveness of the

brakes by applying above-normal braking

pressure at higher speeds. This will also

enhance the grip of the brake pads.

If the parking brake is released and the

brake warning lamp in the instrument

cluster stays on, the brake fluid level in the

reservoir is too low.

Brake pad wear or a leak in the system may

be the reason for low brake fluid in the

reservoir.

Have the brake system inspected

immediately. Contact an authorized

Mercedes-Benz Center.

All checks and service work on the brake

system should be carried out by qualified

technicians only. Contact an authorized

Mercedes-Benz Center.

Only install brake pads and brake fluid

recommended by Mercedes-Benz.

Warning! G

After driving in heavy rain for some time

without applying the brakes or through wa-

ter deep enough to wet brake components,

the first braking action may be somewhat

reduced and increased pedal pressure may

be necessary to obtain expected braking ef-

fect. Maintain a safe distance from vehicles

in front.

Resting your foot on the brake pedal will

cause excessive and premature wear of the

brake pads.

It can also result in the brakes overheating,

thereby significantly reducing their effec-

tiveness. It may not be possible to stop the

vehicle in sufficient time to avoid an acci-

dent.

Be very careful not to endanger other

road users when you apply the brakes.

Refer to the description of the Brake

Assist System (BAS) (컄 page 78).

Warning! G

If other than recommended brake pads are

installed, or other than recommended brake

fluid is used, the braking properties of the

vehicle can be degraded to an extent that

safe braking is substantially impaired. This

could result in an accident.

267

Operation

Driving instructions

After hard braking, it is advisable to drive

on for some time, rather than immediately

parking, so that the air stream will cool

down the brakes faster.

Driving off

Apply the brakes to test them briefly after

driving off. Perform this procedure only

when the road is clear of other traffic.

Warm up the engine smoothly. Do not

place full load on the engine until the

operating temperature has been reached.

When starting off on a slippery surface, do

not allow a drive wheel to spin for an

extended period with the ESP switched off.

Doing so may cause serious damage to the

drivetrain which is not covered by the

Mercedes-Benz Limited Warranty.

Parking

When driving down long and steep

grades, relieve the load on the brakes

by shifting into a lower gear to use the

engine’s braking power. This helps

prevent overheating of the brakes and

reduces brake pad wear.

Simultaneously depressing the

accelerator pedal and applying the

brake reduces engine performance and

causes premature brake and drivetrain

wear.

Set the parking brake whenever park-

ing or leaving the vehicle. In addition,

move gear selector lever to position P

(manual transmission: first or reverse

gear).

When parking on hills, always turn front

wheels towards the road curb.

Warning! G

Do not park this vehicle in areas where

combustible materials such as grass, hay or

leaves can come into contact with the hot

exhaust system, as these materials could be

ignited and cause a vehicle fire.

To reduce the risk of personal injury as a re-

sult of vehicle movement, before turning off

the engine and leaving the vehicle always:

앫 Keep right foot on brake pedal.

앫 Firmly depress parking brake pedal.

앫 Move the gear selector lever to

position P (manual transmission: first or

reverse gear).

앫 Slowly release brake pedal.

앫 When parked on an incline, turn front

wheels towards the road curb.

앫 Turn the SmartKey in the starter switch

to position 0 and remove the SmartKey

from the starter switch.

앫 Take the SmartKey with you and lock

vehicle when leaving.

268

Operation

Driving instructions

Tires

Treadwear indicators (TWI) are required by

law. These indicators are located in six

places on the tread circumference and

become visible at a tread depth of

approximately

in (1.6 mm), at which

point the tire is considered worn and

should be replaced.

The treadwear indicator appears as a solid

band across the tread.

Specified tire pressures must be main-

tained. This applies particularly if the tires

are subjected to high loads (e.g. high

speeds, heavy loads, high ambient temper-

atures).

Hydroplaning

Depending on the depth of the water layer

on the road, hydroplaning may occur, even

at low speeds and with new tires. Reduce

vehicle speed, avoid track grooves in the

road and apply brakes cautiously in the

rain.

Warning! G

If you feel a sudden significant vibration or

ride disturbance, or you suspect that possi-

ble damage to your vehicle has occurred,

you should turn on the hazard warning flash-

ers, carefully slow down, and drive with cau-

tion to an area which is a safe distance from

the road.

Inspect the tires and the vehicle underbody

for possible damage. If the vehicle or tires

appear unsafe, have it towed to the nearest

Mercedes-Benz Center or tire dealer for

repairs.

Warning! G

Although the applicable federal motor

vehicle safety laws consider a tire to be

worn when the treadwear indicators (TWI)

become visible at approximately

(1.6 mm), we recommend that you do not

allow your tires to wear down to that level.

As tread depth approaches

in (3 mm),

the adhesion properties on a wet road are

sharply reduced.

Depending upon the weather and/or road

surface (conditions), the tire traction varies

widely.

Warning! G

Do not drive with a flat tire. A flat tire affects

the ability to steer or brake the vehicle. You

may lose control of the vehicle. Continued

driving with a flat tire or driving at high

speed with a flat tire will cause excessive

heat build-up and possibly a fire.

269

Operation

Driving instructions

Tire traction

The safe speed on a wet, snow covered or

icy road is always lower than on a dry road.

You should pay particular attention to the

condition of the road whenever the outside

temperatures are close to the freezing

point.

Mercedes-Benz recommends M+S rated

radial-ply tires with a minimum tread depth

of approximately

in (4 mm) on all four

wheels for the winter season to ensure

normal balanced handling characteristics.

On packed snow, they can reduce your

stopping distance compared to summer

tires. Stopping distance, however, is still

considerably greater than when the road is

not covered with snow or ice. Exercise ap-

propriate caution.

Tire speed rating

Regardless of the tire speed rating, local

speed limits should be obeyed. Use

prudent driving speeds appropriate to

prevailing conditions.

Warning! G

If ice has formed on the road, tire traction

will be substantially reduced. Under such

weather conditions, drive, steer and brake

with extreme caution.

Avoid spinning of one drive wheel. This

may cause serious damage to the

drivetrain which is not covered by the

Mercedes-Benz Limited Warranty.

Warning! G

Even when permitted by law, never operate

a vehicle at speeds greater than the maxi-

mum speed rating of the tires.

Exceeding the maximum speed for which

tires are rated can lead to sudden tire

failure, causing loss of vehicle control and

possibly resulting in an accident and/or

personal injury and possible death, for you

and for others.

Winter driving instructions

The most important rule for slippery or icy

roads is to drive sensibly and to avoid

abrupt acceleration, braking and steering

maneuvers. Do not use the cruise control

system under such conditions.

When the vehicle is in danger of skidding,

move gear selector lever to position N or in

case of manual transmission declutch.

Try to keep the vehicle under control by

corrective steering action.

For information on tire speed rating for

winter tires, see “Winter tires”

(컄 page 290).

For information on driving with snow

chains, see “Snow chains”

(컄 page 291).

Warning! G

On slippery road surfaces, never downshift

in order to obtain braking action. This could

result in drive wheel slip and reduced

vehicle control. Your vehicle’s ABS will not

prevent this type of control loss.

271

Operation

Driving instructions

Road salts and chemicals can adversely

affect braking efficiency. Increased pedal

force may become necessary to produce

the normal braking effect.

Depressing the brake pedal periodically

when traveling at length on salt-strewn

roads can bring road-salt-impaired braking

efficiency back to normal.

If the vehicle is parked after being driven

on salt-treated roads, the braking

efficiency should be tested as soon as

possible after driving is resumed.

For more information, see “Winter driving”

(

컄 page 290).

Standing water

Warning! G

Make sure not to endanger any other road

users when carrying out these braking

maneuvers.

Warning! G

If the vehicle becomes stuck in snow, make

sure snow is kept clear of the exhaust pipe

and from around the vehicle with the engine

running. Otherwise, deadly carbon monox-

ide (CO) gases may enter vehicle interior re-

sulting in unconsciousness and death.

To assure sufficient fresh air ventilation,

open a window slightly on the side of the

vehicle not facing the wind

Warning! G

The outside temperature indicator is not

designed to serve as an ice-warning device

and is therefore unsuitable for that purpose.

Indicated temperatures just above the

freezing point do not guarantee that the

road surface is free of ice.

Do not drive through flooded areas or

water of unknown depth. Before driving

through water, determine its depth.

Never accelerate before driving into

water. The bow wave could force water

into the engine and auxiliary equip-

ment, thus damaging them.

If you must drive through standing wa-

ter, drive slowly to prevent water from

entering the passenger compartment

or the engine compartment. Water in

these areas could cause damage to

electrical components or wiring of the

engine or transmission, or could result

in water being ingested by the engine

through the air intake causing severe

internal engine damage. Any such

damage is not covered by the

Mercedes-Benz Limited Warranty.

Driving abroad

Abroad, there is an extensive

Mercedes-Benz service network at your

disposal. If you plan to drive into areas

which are not listed in the index of your

Mercedes-Benz Center directory, you

should request pertinent information from

an authorized Mercedes-Benz Center.

Control and operation of radio

transmitters

COMAND*, radio and telephone*

Telephones* and two-way radios

Radio transmitters, such as a portable

telephone or a citizens band unit should

only be used inside the vehicle if they are

connected to an antenna that is installed

on the outside of the vehicle.

Refer to the radio transmitter operation

instructions regarding use of an external

antenna.

Warning! G

Always fasten items being carried as

securely as possible.

In an accident, during hard braking or sud-

den maneuvers, loose items will be thrown

around inside the vehicle, and cause injury

to vehicle occupants unless the items are

securely fastened in the vehicle.

The trunk is the preferred place to carry

objects.

Warning! G

Please do not forget that your primary

responsibility is to drive the vehicle safely.

Only operate the COMAND (Cockpit

Management and Data System), radio or

telephone

if road, weather and traffic

conditions permit.

Bear in mind that at a speed of just 30 mph

(approximately 50 km/h), your vehicle is

covering a distance of 44 feet

(approximately 14 m) every second.

Observe all legal requirements

Warning! G

Never operate radio transmitters equipped

with a built-in or attached antenna (i.e. with-

out being connected to an external antenna)

from inside the vehicle while the engine is

running. Doing so could lead to a malfunc-

tion of the vehicle’s electronic system,

possibly resulting in an accident and

personal injury.

273

Operation

Driving instructions

Catalytic converter

Your Mercedes-Benz is equipped with

monolithic-type catalytic converters, an

important element in conjunction with the

oxygen sensors to achieve substantial

control of the pollutants in the exhaust

emissions. Keep your vehicle in proper

operating condition by following our

recommended maintenance instructions

as outlined in your Maintenance Booklet.

Emission control

Certain systems of the engine serve to

keep the toxic components of the exhaust

gases within permissible limits required by

law.

These systems, of course, will function

properly only when maintained strictly

according to factory specifications. Any

adjustments on the engine should,

therefore, be carried out only by qualified

Mercedes-Benz Center authorized techni-

cians. Engine adjustments should not be

altered in any way. Moreover, the specified

service jobs must be carried out regularly

according to Mercedes-Benz servicing

requirements. For details refer to the

Maintenance Booklet.

To prevent damage to the catalytic

converters, only use premium unleaded

gasoline in this vehicle.

Any noticeable irregularities in engine

operation should be repaired promptly.

Otherwise, excessive unburned fuel

may reach the catalytic converter,

causing it to overheat and start a fire.

Warning! G

As with any vehicle, do not idle, park or

operate this vehicle in areas where combus-

tible materials such as grass, hay or leaves

can come into contact with the hot exhaust

system, as these materials could be ignited

and cause a vehicle fire.

274

Operation

Driving instructions

Coolant temperature

During severe operating conditions and

stop-and-go city traffic, the coolant

temperature may rise close to

approximately 248°F (120°C).

The engine should not be operated with

the coolant temperature over 248°F

(120°C). Doing so may cause serious

engine damage which is not covered by the

Mercedes-Benz Limited Warranty.

Warning! G

Inhalation of exhaust gas is hazardous to

your health. All exhaust gas contains carbon

monoxide, and inhaling it can cause

unconsciousness and lead to death.

Do not run the engine in confined areas

(such as a garage) which are not properly

ventilated. If you think that exhaust gas

fumes are entering the vehicle while driving,

have the cause determined and corrected

immediately. If you must drive under these

conditions, drive only with at least one

window fully open at all times.

Warning! G

앫 Driving when your engine is badly

overheated can cause some fluids,

which may have leaked into the engine

compartment, to catch fire. You could

be seriously burned.

앫 Steam from an overheated engine can

cause serious burns and can occur just

by opening the hood. Stay away from

the engine if you see or hear steam com-

ing from it.

Turn off the engine, get out of the vehicle

and do not stand near the vehicle until the

engine has cooled down.

Operation

Engine compartment

Battery

Your vehicle’s battery is located in the

engine compartment on the right hand

side (컄 page 360).

The battery should always be sufficiently

charged in order to achieve its rated

service life. Refer to Maintenance Booklet

for battery maintenance intervals.

If you use your vehicle mostly for

short-distance trips, you will need to have

the battery charge checked more

frequently.

When replacing the battery, always use

batteries approved by Mercedes-Benz.

If you do not intend to operate your vehicle

for an extended period of time, consult an

authorized Mercedes-Benz Center about

steps you need to observe.

Batteries contain materials that can harm

the environment if disposed of improperly.

Recycling of batteries is the preferred

method of disposal. Many states require

sellers of batteries to accept old batteries

for recycling.

Observe all safety instructions

and precautions when handling

automotive batteries.

Risk of explosion

Keep flames or sparks away

from battery. Do not smoke.

Battery acid is caustic. Do not

allow it to come into contact

with skin, eyes or clothing.

Windshield washer system and

headlamp cleaning system*

The windshield washer reservoir is located

in the engine compartment.

1 Washer fluid reservoir cap

Fluid for the windshield washer system and

the headlamp cleaning system* is supplied

from the windshield washer reservoir. It

has a capacity of:

앫 3.2 US qt (3.0 l) in vehicles without

headlamp cleaning system*

앫 6.4 US qt (6.0 l) in vehicles with

headlamp cleaning system*

During all seasons, add MB Windshield

the windshield washer fluid in a suitable

container.

왘 Refill the reservoir with MB Windshield

Washer Concentrate and water (or

commercially available premixed

windshield washer solvent/antifreeze,

depending on ambient temperatures).

Always use washer solvent/antifreeze

where temperatures may fall below the

freezing point. Failure to do so could

result in damage to the washer

system/reservoir.

For more information, see “Windshield

washer and headlamp cleaning system*”

(

컄 page 396).

Only use washer fluid which is suitable

for plastic lenses. Improper washer

fluid can damage the plastic lenses of

the headlamps.

Warning! G

Washer solvent/antifreeze is highly flamma-

ble. Do not spill washer solvent/antifreeze

on hot engine parts, because it may ignite

and burn. You could be seriously burned.

286

Operation

Tires and wheels

See an authorized Mercedes-Benz Center

for information on tested and

recommended rims and tires for summer

and winter operation. They can also offer

advice concerning tire service and

purchase.

Retreaded tires are not tested or recom-

mended by Mercedes-Benz, since previous

damage cannot always be recognized on

retreads. Mercedes-Benz can therefore

not assure the operating safety of the

vehicle when such tires are used.

See an authorized Mercedes-Benz Center

for information on tested and

recommended rims and tires for summer

and winter operation.

Important guidelines

앫 Only use sets of tires and rims of the

same type and make.

앫 Tires must be of the correct size for the

rim.

앫 Break in new tires for approximately

60 miles (100 km) at moderate

speeds.

앫 Regularly check the tires and rims for

damage. Dented or bent rims can

cause tire pressure loss and damage to

the tire beads.

앫 If vehicle is heavily loaded, check tire

pressure and correct as required.

앫 Do not allow your tires to wear down

too far. Adhesion properties on wet

roads are sharply reduced at tread

depths under

in (3 mm).

앫 When replacing individual tires, you

should mount new tires on the front

wheels first (on vehicles with

same-sized wheels all around).

Warning! G

Replace rims or tires with the same designa-

tion, manufacturer and type as shown on the

original part. See an authorized

Mercedes-Benz Center for further informa-

tion. If incorrectly sized rims and tires are

mounted:

앫 The wheel brakes or suspension

components can be damaged.

앫 The correct operating clearance of the

wheels and the tires are no longer

guaranteed.

Warning! G

Worn, old tires can cause accidents. If the

tire tread is badly worn, or if the tires have

sustained damage, replace them.

When replacing rims, only use genuine

Mercedes-Benz wheel bolts specified for the

particular rim type. Failure to do so can

result in the bolts loosening and possibly an

accident.

287

Operation

Tires and wheels

Life of tire

The service life of a tire is dependent upon

varying factors including but not limited to:

앫 Driving style

앫 Tire pressure

앫 Distance driven

Direction of rotation

Unidirectional tires offer added advan-

tages, such as better hydroplaning perfor-

mance. To benefit, however, you must

make sure the tires rotate in the direction

specified.

An arrow on the sidewall indicates the

intended direction of tire rotation.

Checking tire inflation pressure

Correct the tire pressure only when tires

are cold.

Regularly check your tire pressure at

intervals of no more than 14 days.

If the tires are warm you should only

correct the tire pressure if it is too low for

current operating conditions.

A table on the fuel filler flap lists the

specified tire inflation pressures for warm

and cold tires as well as for various

operating conditions.

Warning! G

Tires and spare tire should be replaced after

six years, regardless of the remaining tread.

Keep unmounted tires in a cool, dry

place with as little exposure to light as

possible. Protect tires from contact

with oil, grease and gasoline.

Warning! G

If the tire pressure drops repeatedly:

앫 Check the tires for punctures from

foreign objects.

앫 Check to see whether air is leaking from

the valves or from around the rim.

288

Operation

Tires and wheels

Tire pressure changes by approx. 1.5 psi

(0.1 bar) per 18°F (10°C) of air tempera-

ture change. Keep this in mind when

checking tire pressure where the tempera-

ture is different from the outside tempera-

ture.

Tire temperature and tire pressure are also

increased while driving, depending on the

driving speed and the tire load.

Check the spare tire periodically for condi-

tion and inflation. Spare tires will age and

become worn over time even if never used,

and thus should be inspected and replaced

when necessary.

The pressures listed for light loads are

minimum values offering high driving

comfort.

Increased inflation pressures listed for

heavier loads may also be used for light

loads. These higher pressures produce

favorable handling characteristics. The

ride of the vehicle, however, will be

somewhat harder. Never exceed the

max. values or inflate tires below the

min. values listed in the fuel filler flap.

Warning! G

Follow recommended inflation pressures.

Do not overinflate tires. Overinflated tires

can result in sudden deflation (blowout)

because they are more likely to become

punctured or damaged by road debris,

potholes, etc.

Do not underinflate tires. Underinflated tires

wear unevenly, adversely affect handling

and fuel economy, and are more likely to fail

from being overheated.

Do not overload the tires by exceeding the

specified vehicle capacity weight (as indi-

cated by the label on the pillar in the driver’s

door opening). Overloading the tires can

overheat them, possibly causing a blowout.

289

Operation

Tires and wheels

Rotating tires

Tire rotation can be performed on vehicles

with tires of the same dimension all

around. If your vehicle is equipped with

tires of the same dimension all around,

tires can be rotated, observing a a

front-to-rear rotation pattern that will

maintain the intended rotation (spinning)

direction of the tire (

컄 page 287).

In some cases, such as when your vehicle

is equipped with mixed-size tires (different

tire dimension front vs. rear), tire rotation

is not possible.

If applicable to your vehicle's tire configu-

ration, tires can be rotated according to

the tire manufacturer's recommended in-

tervals in the tire manufacturer's warranty

pamphlet located in your vehicle literature

portfolio. If none is available, tires should

be rotated every 3000 to 6000 miles

(5000 to 10000 km), or sooner if neces-

sary, according to the degree of tire wear.

The same rotation (spinning) direction

must be maintained (

컄 page 287).

Rotate tires before the characteristic tire

wear pattern becomes visible (shoulder

wear on front tires and tread center wear

on rear tires).

Thoroughly clean the mounting face of

wheels and brake disks, i.e. the inner side

of the wheels/tires, during each rotation.

Check for and ensure proper tire inflation

pressure.

For information on wheel change, see the

“Practical hints” section (

컄 page 329) and

(컄 page 353).

Warning! G

Rotate front and rear wheels only if the tires

are of the same dimension.

If your vehicle is equipped with mixed-size

tires (different tire dimensions front vs.

rear), tire rotation is not possible.

Warning! G

Have the tightening torque checked after

changing a wheel. Wheels could become

loose if not tightened with a torque of

80 lb-ft (110 Nm).

Only use genuine Mercedes-Benz wheel

bolts specified for your vehicle's rims.

290

Operation

Winter driving

Before the onset of winter, have your

vehicle winterized at an authorized

Mercedes-Benz Center. This service

includes:

앫 Check of anticorrosion and antifreeze

concentration.

앫 Addition of cleaning concentrate to the

water of the windshield and headlamp

cleaning system. Add MB Concentrate

“S” to a premixed windshield washer

solvent/antifreeze which is formulated

for below freezing temperatures

(

컄 page 396).

앫 Battery test. Battery capacity drops

with decreasing ambient temperature.

A well charged battery helps to make

sure that the engine can be started,

even at low ambient temperatures.

앫 Tire change. Mercedes-Benz recom-

mends M+S rated radial-ply tires with a

minimum tread depth of approximately

in (4 mm) on all four wheels for the

winter season.

Winter tires

Always use winter tires at temperatures

below 45°F (7°C) and whenever wintry

road conditions prevail. Use of winter tires

is the only way to achieve the maximum

effectiveness of the ABS, ESP and 4MATIC

in winter operation.

For safe handling, make sure that all

mounted winter tires are of the same make

and have the same tread design.

Always observe the speed rating of the

winter tires installed on your vehicle. If the

maximum speed for which your tires are

rated is below the speed rating of your

vehicle, you must place a notice to this

effect where it will be seen by the driver.

Such notices are available from your tire

dealer or from any authorized

Mercedes-Benz Center.

Warning! G

Winter tires with a tread depth under

(4 mm) must be replaced. They are no

longer suitable for winter operation.

Warning! G

If you use your spare tire when winter tires

are fitted on the other wheels, be aware that

the difference in tire characteristics may

very well impair turning stability and that

overall driving stability may be reduced.

Adapt your driving style accordingly.

Have the spare tire replaced with a winter

tire at the nearest authorized

Mercedes-Benz Center.

Vehicle care

왔 Vehicle care

Cleaning and care of the vehicle

While in operation, even while parked, your

vehicle is subjected to varying external

influences which, if gone unchecked, can

attack the paintwork as well as the under-

body and cause lasting damage.

Such damage is caused not only by

extreme and varying climatic conditions,

but also by:

앫 Air pollution

앫 Road salt

앫 Tar

앫 Gravel and stone chipping

To avoid paint damage, you should

immediately remove:

앫 Grease and oil

앫 Fuel

앫 Coolant

앫 Brake fluid

앫 Bird droppings

앫 Insects

앫 Tree resins, etc.

Frequent washing reduces and/or elimi-

nates the aggressiveness and potency of

the above adverse influences.

More frequent washings are necessary to

deal with unfavorable conditions:

앫 near the ocean

앫 in industrial areas (smoke, exhaust

emissions)

앫 during winter operation

You should check your vehicle from time to

time for stone chipping or other damage.

Any damage should be repaired as soon as

possible to prevent corrosion.

In doing so, do not neglect the underbody

of the vehicle. A prerequisite for a thor-

ough check is a washing of the underbody

followed by a thorough inspection. Dam-

aged areas need to be re-undercoated.

Your vehicle has been treated at the facto-

ry with a wax-base rustproofing in the body

cavities which will last for the lifetime of

the vehicle. Post-production treatment is

neither necessary nor recommended by

Mercedes-Benz because of the possibility

of incompatibility between materials used

in the production process and others

applied later.

Warning! G

Many cleaning products can be hazardous.

Some are poisonous, others are flammable.

Always follow the instructions on the partic-

ular container. Always open your vehicle’s

doors or windows when cleaning the inside.

Never use fluids or solvents that are not

designed for cleaning your vehicle.

Operation

Vehicle care

We have selected car-care products and

compiled recommendations which are

specially matched to our vehicles and

which always reflect the latest technology.

You can obtain Mercedes-Benz approved

car-care products at an authorized

Mercedes-Benz Center.

Scratches, corrosive deposits, corrosion or

damage due to negligent or incorrect care

cannot always be removed or repaired with

the car-care products recommended here.

In such cases it is best to seek aid at an

authorized Mercedes-Benz Center.

The following topics deal with the cleaning

and care of your vehicle and give important

“how-to” information as well as references

to Mercedes-Benz approved car-care

products.

Additional information can be found in the

booklet “Vehicle Care Guide”.

Power washer

When using a power washer for cleaning

the vehicle, always observe the manu-

facturer’s operating instructions.

Tar stains

Quickly remove tar stains before they dry

and become more difficult to remove. A tar

remover is recommended.

Paintwork, painted body components

Mercedes-Benz approved Paint Care

should be applied when water drops on the

paint surface do not “bead up”, normally

every three to five months, depending on

climate and washing detergent used.

Mercedes-Benz approved Paint Cleaner

should be applied if the paint surface

shows signs of embedded dirt (i.e. loss of

gloss).

Do not apply any of these products or wax

if your vehicle is parked in the sun or if the

hood is still hot.

Use the appropriate MB-Touch-Up Stick

for quick and provisional repairs of minor

paint damage (i.e. chips from stones,

vehicle doors, etc.).

Never use a round nozzle to

power-wash tires. The intense jet of

water can result in damage to the tire.

Always replace a damaged tire.

Always keep the jet of water moving

across the surface. Do not aim directly

at electrical parts, electrical connec-

tors, seals, or other rubber parts.

Operation

Vehicle care

Engine cleaning

Prior to cleaning the engine compartment,

make sure to protect electrical compo-

nents and connectors from the intrusion of

water and cleaning agents.

Corrosion protection, such as MB Anticor-

rosion Wax, should be applied to the

engine compartment after every engine

cleaning. Before applying, all control

linkage bushings and joints should be

lubricated. The poly-V-belt and all pulleys

should be protected from any wax.

Vehicle washing

Do not use hot water or wash your vehicle

in direct sunlight. Only use a mild car wash

detergent, such as Mercedes-Benz

approved Car Shampoo.

Thoroughly spray the vehicle with a dif-

fused jet of water. Direct only a very weak

spray towards the ventilation intake. Use

plenty of water and rinse the sponge and

chamois frequently.

Rinse with clear water and thoroughly dry

with a chamois. Do not allow cleaning

agents to dry on the finish.

Due to the width of the vehicle, fold in

exterior rear view mirrors prior to running

the vehicle through an automatic car wash

to prevent damage to the mirrors.

In the winter, thoroughly remove all traces

of road salt as soon as possible.

When washing the underbody, do not

forget to clean the inner sides of the

wheels.

Ornamental moldings

For regular cleaning and care of very dirty

chrome-plated parts, use a chrome

cleaner.

Headlamps, tail lamps, side markers,

turn signal lenses

Use a mild car wash detergent, such as

Mercedes-Benz approved Car Shampoo,

with plenty of water.

To prevent scratches, never apply strong

force and only use a soft, non-scratchy

cloth when cleaning the lenses. Do not

attempt to wipe dirty lenses with a dry

cloth or sponge.
