Driving and operating149
Ignition on power mode: press and
hold Engine Start/Stop button for
6 seconds without operating clutch or brake pedal. The green LED in the
button illuminates, diesel engine is
preheating. Control indicators light up
and the most electrical functions are
operable.
Engine start: operate clutch pedal
(manual transmission) or brake pedal (automatic transmission) and press
Engine Start/Stop button once more.
Release button after starting
procedure begins.
Ignition off: press Engine Start/Stop
button briefly in each mode or when
engine is running. Some functions
remain active until driver's door is
opened, if ignition was on before.
Steering wheel lock
The steering wheel lock activates
automatically when:
■ the vehicle is stationary and
■ the ignition has been switched off and
■ the driver's door is opened.To release steering wheel lock, open
and close driver's door and switch on accessory mode or start the engine
directly.9 Warning
If the vehicle battery is discharged,
the vehicle must not be towed,
tow-started or jump-started as the
steering wheel lock cannot be
disengaged.
Emergency operation on
vehicles with electronic key
system
If either the electronic key fails or the
battery of the electronic key is weak,
the Driver Information Centre may
display No Remote Detected or
Replace Battery in Remote Key when
you try to start the vehicle.Open the centre console storage area by lifting up the armrest. Place the
electronic key in the transmitter
pocket. Depress the clutch pedal
(manual transmission) or the brake
pedal (automatic transmission) and
press the Engine Start/Stop button.
To switch off the engine, press the Engine Start/Stop button again.
Remove the electronic key from the
transmitter pocket.
This option is intended for
emergencies only. Replace the
electronic key battery as soon as
possible 3 21.

Fault9Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Manual parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
Control indicator R 3 101.
Electric parking brake
Applying when vehicle is stationary
Pull switch m for approx.
one second, the electric parking
brake operates automatically with an adequate force. For maximum force,
e.g. parking with trailer or on inclines,
pull switch m twice.
The electric parking brake is applied
when control indicator m lights up
3 101.
The electric parking brake can always
be activated, even if the ignition is off.
Driving and operating173
vehicle speed increases or decreasesto follow the vehicle in front, but willnot exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store
and maintain speeds over approx.
15 mph and brakes automatically to
follow a slower vehicle driving ahead
to a minimum speed of 9 mph. On vehicles with automatic transmission
the system brakes to a stop.
Adaptive cruise control uses a radar
sensor to detect the vehicles ahead.
If no vehicle is detected in the driving path, the adaptive cruise control will
behave like a traditional cruise
control.
For safety reasons, the system
cannot be activated before the brake
pedal has been depressed once
since switching on ignition. Activation
in first gear is not possible.
Adaptive cruise control is mainly
advised to be used on long straight
roads like highways or country roads
with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
Control indicator A 3 105, m 3 105,
C 3 105.9 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.
Switching on
Press button C to switch on adaptive
cruise control. The control indicator
m or C in the instrument cluster
illuminates white.
Activation by setting the speed Adaptive cruise control can be
activated between 15 mph and
112 mph.
Accelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and

If there is no vehicle ahead or the
vehicle ahead is out of range, two
dashes will be displayed: -.- s.
If Adaptive cruise control is active,
this page shows the following
distance setting instead 3 172.
Active Emergency Braking Active emergency braking can help to reduce the damage from crashes with vehicles and obstacles directly
ahead, when a collision can no longer
be avoided either by manual braking
or by steering. Before the active
emergency braking applies, the driver is warned by the forward collision
alert 3 180.
The feature uses various inputs (e.g.
radar sensor, brake pressure, vehicle speed) to calculate the probability of
a frontal collision.
Active emergency braking operates automatically above walking speed, provided that Auto Collision
Preparation setting is not deactivated
in the vehicle personalisation menu
3 117.The system includes:
■ Brake preparation system
■ Emergency automatic braking
■ Forward looking brake assist9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver must continue to apply the brake
pedal as the driving situation
dictates.
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.
Emergency automatic braking
After the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of
the collision.
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,
depressing the brake pedal slightly
results in immediate hard braking.
This function helps the driver brake
quicker and harder before the
imminent collision.9 Warning
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 stopped vehicles,
