Driving comfort

Manual gearbox

Vehicle equipment

You can shift gears while cruise control is acti‐

vated. An indicator light notifies you that you

should shift gears when you drive for an exten‐

ded period at very high or very low engine

speeds, or the system is deactivated.

This chapter describes all the standard equip‐

ment, national-market-specific equipment and

optional extras offered in the model series.

Consequently, you will find that it contains de‐

scriptions of items not available in a particular

vehicle on account of a combination of options,

for example, or the constraints applying to cer‐

tain national-market versions. This also applies

to safety-relevant functions and systems.

One lever for all functions

Country-specific regulations must be observed

when using the corresponding functions and

systems.

Cruise Control

Memorising and maintaining speed or ac‐

celerating

Principle

Cruise control with braking function is available

at speeds above approximately

Memorising and maintaining speed or de‐

celerating

30 km/h/20 mph. The car then memorises and

maintains the speed that you specify using the

lever on the steering column. In order to main‐

tain the specified speed, the system brakes

the vehicle when the engine braking effect is

insufficient on downhill gradients.

Deactivating cruise control

Recalling a speed memorised beforehand

Maintaining current speed

Tap the stalk, arrow 1, or pull it briefly, arrow 2.

Do not use cruise control

The car's current speed is memorised and

maintained. It is displayed in the speedometer

and briefly in the instrument cluster.

Do not use the system if unfavourable

conditions do not permit driving at constant

speed, for example:

On uphill gradients, it may prove impossible to

maintain the set speed if current engine power

output is insufficient. On downhill gradients,

the system will brake the car slightly if engine

braking alone is insufficient.

▷

On stretches with many corners and

bends.

▷

In heavy traffic.

If the road is icy, if there is fog, snow, rain

or a loose road surface.

Otherwise you could lose control of the car

and cause an accident as a result.◀

Increasing desired speed

Press the lever repeatedly to the resistance

point or beyond, arrow 1, until the desired

speed is set.

Driving comfort

Controls

▷

Each time the lever is pressed lightly to the

resistance point, the desired speed is in‐

creased by approximately 1 km/h/1 mph.

▷

When DSC or ABS intervenes to stabilise

the car.

Cruise control is not deactivated by pressing

the accelerator pedal. Once the accelerator

pedal is released, the memorised speed is

again achieved and maintained.

Each time the lever is pressed beyond the

resistance point, the desired speed is in‐

creased to the next multiple of 10 km/h or

5 mph on the speedometer display.

Warning light

The system memorises and maintains the

speed.

The warning light comes on for ex‐

ample if cruise control is interrupted

by DSC intervention.

Accelerating using the lever

Accelerating slightly:

Press the lever to the resistance point longer,

arrow 1, until the desired speed is reached.

Deactivating the system

▷

Push lever up or down twice, arrow 3.

Turn off ignition.

Accelerating significantly:

Press the lever longer beyond the resistance

point, arrow 1, until the desired speed is

reached.

The stored speed is deleted.

Recalling a speed memorised

beforehand

Press the button, arrow 4. The speed last

memorised is recalled and maintained.

The car accelerates without the accelerator

pedal being pressed. The system memorises

and maintains the speed.

Reducing speed

Pull the lever repeatedly, arrow 2, until the de‐

sired speed is displayed.

Displays in the instrument cluster

Functions analogous to increasing desired

speed, except that the speed is reduced.

Interrupt system

Tap the lever upwards or downwards, arrow 3.

The readings in the speedometer change col‐

our.

Memorised speed

The system also interrupts automatically in the

following situations:

Selected speed is displayed briefly

▷

If the brake is applied.

If --- km/h shows briefly in the instrument clus‐

ter, it is possible that the preconditions for op‐

eration might not have been met.

If the car has a manual gearbox, when you

shift gears very slowly or shift into neutral.

▷

If the car has a sport-automatic transmis‐

sion, when you select transmission posi‐

tion N.

View the Check Control messages, see

page 71.

If you activate DTC or deactivate DSC.

Controls

Driving comfort

Due to physical conditions the system could

warn when it is too late.◀

Malfunction

The warning light comes on when the

system has failed.

Limits of the ultrasound measurement

Further information, see page 184.

Detection of objects might not be possible if

the physical limits of the ultrasonic measuring

principle are exceeded, for instance by:

Park Distance Control, PDC

▷

Trailer noses and hitches.

Thin or wedge-shaped objects.

Low objects.

Principle

PDC assists you with parking.

Objects with corners and sharp edges.

Slow approach to an object behind the vehicle,

and also in front of the vehicle if the appropri‐

ate equipment is fitted, is indicated by acoustic

signals.

Low objects already indicated, such as kerbs,

may enter the sensors' blind areas before or

after a continuous audible signal is given.

Higher, protruding objects such as ledges may

not be detectable.

Measurement

Ultrasonic sensors in each bumper measure

the distance.

False alarms

The range is approximately 2 m, 6 ft.

An audible warning is only issued:

Under the following conditions, PDC can issue

a warning although there is no obstacle in the

detection range:

▷

From the front sensors and the two rear

corner sensors at approximately 60 cm,

24 in.

▷

In heavy rain.

If the sensors are very dirty or covered with

ice.

▷

For the centre rear sensors at approxi‐

mately 1.50 m, 5 ft.

▷

If the sensors are covered with snow.

On rough road surfaces.

System limits

In large, rectangular buildings with smooth

walls, for example underground car parks.

Also monitor the traffic situation

PDC is no substitute for your personal

assessment of the traffic situation. Also moni‐

tor the traffic situation around the vehicle by

observing it directly. Otherwise, there is a dan‐

ger that accidents might occur due to other

road users or objects located outside of detec‐

tion range of the PDC, for example.

▷

Due to dense exhaust gas.

Due to other ultrasonic sources, for exam‐

ple sweeping machines, steam-jet cleaners

or neon lights.

Automatic activation

With the engine running or the ignition

switched on, engage reverse gear.

Loud sound sources outside or inside the car

can drown out the PDC signal.◀

Avoid driving fast with PDC active

Avoid approaching an object at speed.

Avoid moving off at speed while PDC is not yet

active.

Driving comfort

Controls

▷

If the vehicle is more than approximately

10 cm, 4 in away from an object.

Automatic switch-off when vehicle

moves forward

The system switches off when the vehicle

moves forward a certain distance or reaches a

certain speed.

If gearbox position P is engaged.

Malfunction

If required, switch on the system again.

The indicator light in the instrument

cluster comes on. PDC has failed.

Switching on/off manually

Have the system checked.

To ensure correct functionality:

▷

Keep sensors clean and free from ice.

Do not spray the sensors with high-pres‐

sure cleaners for an extended period of

time and maintain a distance of at least

30 cm, 12 in.

Manual operation

Press the button.

The LED above the button flashes in addition.

▷

On: LED is illuminated.

Off: LED turns off.

Audible warning signals

An intermittent sound indicates the position of

an object as the car approaches it. For in‐

stance, if an object is identified to the rear left

of the car, the warning signal sounds from the

rear left loudspeaker.

The shorter the distance to an object be‐

comes, the shorter the intervals become.

If the distance to a detected object is less than

approximately 25 cm, 10 in, a continuous tone

sounds.

If there are objects in front of and behind the

vehicle, an alternating continuous tone

sounds.

An intermittent continuous tone is interrupted

after approximately three seconds:

▷

If you remain in front of an object that was

detected by only one of the corner sen‐

sors.

▷

If you are driving parallel to a wall.

The sound signal is switched off:
