Adaptive cruise control

Adaptive cruise control is an

enhancement to conventional cruise

control with the additional feature of

maintaining a certain distance behind

the vehicle ahead.

Driving and operating

Switching on the system

179

Adaptive cruise control automatically

decelerates the vehicle when

approaching a slower moving vehicle.

It then adjusts the vehicle speed to

follow the vehicle ahead at the

selected following distance. The

vehicle speed increases or decreases

to follow the vehicle in front, but will

not exceed the set speed. It may

apply limited braking with activated

brake lights.

For additional information including a

video, visit us online.

Adaptive cruise control is mainly

advised to be used on long straight

roads like motorways or country

roads with steady traffic. Do not use

the system if it is not advisable to

maintain a constant speed.

Control indicator A 3 113, m 3 113,

C 3 113.

The adaptive cruise control can store

and maintain speeds over approx.

15 mph. On vehicles with automatic

transmission, there is no lower speed

limit and the system can also brake to

a stop.

9 Warning

The complete driver attention is

always required while driving with

adaptive cruise control. The driver

stays fully in control of the vehicle

because the brake pedal, the

accelerator pedal and the cancel

switch have priority over any

adaptive cruise control operation.

Adaptive cruise control can be

activated at speeds above 15 mph on

vehicles with automatic transmission

or 19 mph on vehicles with manual

transmission. The upper speed limit is

112 mph.

Adaptive cruise control uses radar

and camera sensors to detect the

vehicles ahead. If no vehicle is

detected in the driving path, the

adaptive cruise control will behave

like a conventional cruise control.

180

Driving and operating

Accelerate to the desired speed and

turn thumb wheel to SET/-, the

current speed is stored and

maintained.

Once the system is activated,

adaptive cruise control decelerates or

brakes if it detects a vehicle ahead,

which is slower or closer than the

desired following distance.

Increase or reduce speed

The preset speed can be changed by

moving thumb wheel to RES/+ to

increase or SET/- to decrease the

speed. Move thumb wheel repeatedly

to change speed in small steps, move

and hold to change speed in large

steps.

9 Warning

Driver's attention

●

Use adaptive cruise control

carefully on bends or mountain

roads, as it can lose the vehicle

ahead and needs time to detect it

again.

The system's automatic brake

force does not permit hard braking

and the braking level may not be

sufficient to avoid a collision.

On Midlevel display, the stored speed

is indicated in brackets in the Driver

Information Centre when the system

is deactivated but not switched off.

On Uplevel display, the adaptive

cruise control symbol C changes

from green to white when the system

is deactivated but not switched off.

●

After a sudden lane change, the

system needs a certain time to

detect the next preceding

vehicle. So if a new vehicle is

detected, the system may

accelerate instead of braking.

Emergency automatic braking

9 Warning

After activation of brake preparation

system and just before the imminent

collision, this function automatically

applies limited braking to reduce the

impact speed of the collision or

prohibit a crash. Depending on the

situation, the vehicle may

automatically brake moderately or

hard. This front automatic braking can

only occur if a vehicle ahead is

detected, indicated by the vehicle

ahead indicator A 3 186.

If equipped only with front camera the

system operates up to a speed of

50 mph.

Below a speed of 25 mph the system

can apply full braking.

Emergency automatic braking may

slow the vehicle to a complete stop to

try to avoid a potential crash. If this

happens, emergency automatic

braking may engage the electric

parking brake to hold the vehicle at a

stop. To release press the electric

parking brake button or firmly press

the accelerator pedal.

Emergency automatic braking is

an emergency crash preparation

feature and is not designed to

avoid crashes. Do not rely on the

system to brake the vehicle.

Emergency automatic braking will

not brake outside of its operating

speed range and only responds to

detected vehicles.

Active emergency braking is not

designed to apply hard

autonomous braking or to

automatically avoid a collision. It is

designed to reduce the vehicle

speed before a collision. It may not

react for pedestrians or animals.

After a sudden lane change, the

system needs a certain time to

detect the next preceding vehicle.

The complete attention of the

driver is always required while

driving. The driver shall always be

ready to take action and apply the

brakes and steer to avoid

collisions. The system is designed

to work with all occupants wearing

their seat belts.

Forward looking brake assist

In addition to the brake preparation

system and emergency automatic

braking, the forward looking brake

assist function makes the brake assist

more sensitive. Therefore, pressing

the brake pedal less strongly results

in immediate hard braking. This

function helps the driver brake

quicker and harder before the

imminent collision.

Intelligent Brake Assist

If the vehicle is equipped with radar

sensor Intelligent brake assist may

activate when the brake pedal is

applied quickly by providing a boost

to braking based on the speed of

approach and distance to a vehicle

ahead.

If equipped only with front camera the

system operates up to a speed of

52 mph.

The sensor in the windscreen is

blocked by snow, ice, slush, mud,

dirt, windscreen damage or

stickered.

Front pedestrian braking does not

provide an alert or automatically

brake the vehicle, unless it detects

a pedestrian.

The system may not detect

pedestrians, including children,

when the pedestrian is not directly

ahead, not fully visible, not

standing upright, or when part of a

group.

Front pedestrian protection

Front pedestrian protection may help

to avoid or reduce the harm caused

by front-end crashes with nearby

pedestrians when driving in a forward

gear.

●

The system uses the front camera in

the windscreen to detect a pedestrian

directly ahead, in your path.

Front pedestrian protection can

detect and alert to pedestrians in a

forward gear at speeds between

5 mph and 50 mph. Additionally Front

pedestrian protection can provide a

boost to braking or automatically

brake the vehicle.

To avoid malfunction keep the areas

of the camera sensor in the

windscreen and the radar sensor in

the radiator grille always clean from

dirt, dust, ice and snow.

Automatic braking

General information

If a crash into a pedestrian directly

ahead is imminent, and the brakes

have not been applied, Automatic

braking may automatically brake

moderately or brake hard. This can

help to avoid some very low speed

pedestrian crashes or reduce

pedestrian injury.

Automatic braking levels may be

reduced under certain conditions,

such as higher speeds.

If this happens, automatic braking

may engage the Electric parking

brake to hold the vehicle at a stop.

Release the parking brake. Pressing

the accelerator pedal will also release

Automatic braking and Electric

parking brake 3 170.

9 Warning

The driver must always be ready

to take action and apply the brakes

and steer to avoid collisions.

A pedestrian ahead up to a distance

of approx. 40 m is indicated by the

cluster.

9 Warning

Front pedestrian alert

Front pedestrian braking may alert

or automatically brake the vehicle

suddenly in situations where it is

unexpected and undesired. It

could falsely alert or brake for

objects similar in shape or size to

pedestrians, including shadows.

This is normal operation and the

vehicle does not need a service.

To override Automatic braking,

firmly depress the accelerator

pedal, if it is safe to do so.

When approaching a detected

pedestrian too quickly, the collision

alert symbol pops up in the Driver

Information Centre. A warning chime

is provided. The brake system may

prepare for driver braking to occur

more rapidly which can cause a brief,

mild deceleration. Continue to apply
