Driving and operating127turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before removing the ignition
key. Turn the front wheels
towards the kerb.
■ Close the windows and the sunroof.
■ Remove the ignition key. Turn the steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with manual
transmission automated, the
key can only be removed from
the ignition switch when the
parking brake is applied.
■ Lock the vehicle.
■ Activate the anti-theft alarm system.
■ The engine cooling fans may run after the engine has been switchedoff 3 159.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Notice
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.

132Driving and operating
KickdownIf the accelerator pedal is pressed
down completely in automatic mode, the transmission shifts to a lower gear depending on engine speed.
Fault To prevent damage to the manual
transmission automated, the clutch is
engaged automatically at high clutch
temperatures.
In the event of a fault, control indicator g illuminates. Additionally, a
warning message is displayed in the
Driver Information Centre. Vehicle
messages 3 97.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 87.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs a self-test which may be audible.
Control indicator u 3 87.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.

Driving and operating133
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 brake9 Warning
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 87.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
Page 136 of 233
134Driving and operating
soon as the vehicle begins to
accelerate or the two seconds holding
time is over.
The hill start assist is not active during
an Autostop.Ride control systems
Traction Control system
The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC).
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as control indicator b
extinguishes.
When TC operates b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

Deactivation
TC can be switched off when spinningof drive wheels is required: press b
briefly.
A status message appears in the
Driver Information Centre when TC is
deactivated.
TC is reactivated by pressing b
again. A status message pops up in the Driver Information Centre when
TC is reactivated.
TC is also reactivated the next time
the ignition is switched on.
Fault
If there is a fault in the system the
control indicator b illuminates
continuously and a message or a
warning code appears in the Driver
Information Centre. The system is not operational.
Have the cause of the fault remedied
by a workshop.
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning. ESC operates in
combination with the Traction Control system (TC).
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational after each engine
start as soon as control indicator b
extinguishes.
When ESC operates b flashes.

developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of approx. 20 to
