automatically deactivated.
Stop-start system 3 119.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emission. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is depressed. A vehicle battery sensor
ensures that an Autostop is only performed if the vehicle battery is
sufficiently charged for a restart.Activation
The stop-start system is available as soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
Deactivation
Deactivate the stop-start system
manually by pressing Î.
Deactivation is indicated when the
LED in the button illuminates.
Notice
When the fast idle function is

out of neutral (manual transmission)
or N (manual transmission
automated) or other conditions are
not met, start using the ignition key.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted.
If the selector lever is shifted out of
neutral (manual transmission) or N
(manual transmission automated) before depressing the clutch first, a
restart will not take place.
Restart of the engine by the stop- start system
The selector lever must be in neutral (manual transmission) or N (manual
transmission automated) to enable an
automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system. Control
indicator Ï will flash green in the
instrument cluster during an
automatic engine restart.● the stop-start system is manually
deactivated
● the bonnet is opened
● the driver's seat belt is unfastened and the driver's door
is opened
● the engine temperature is too low
● the vehicle battery is discharged
● the brake vacuum is not sufficient
● the vehicle starts to move
● the defrosting function is activated
● the climate control system requests an engine start
● the predetermined timing has been exceeded
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during restart might be noticeable.
If the Infotainment system is active,
audio sound may briefly be reduced
or interrupted during the restart.
Warning chimes 3 91.Fault
If control indicator Ï illuminates
yellow, there is a fault in the stop-start system 3 88. A corresponding
message also appears in the DIC

Driving and operating123Remote control
When increased ground clearance orimproved vehicle access is required,the suspension can be raised or
lowered using the remote control.
Caution
Ensure there is adequate
clearance and that there are no
obstructions when adjusting the
suspension height.
The remote control unit is magnetic
and may be fixed to any metal part of the vehicle or stored in its holder.
With the engine running, press theappropriate button for 2 seconds to
adjust the suspension height.
Indicator light will flash intermittently
while height adjustment is in progress
and illuminates when complete.
If the ignition is switched on with
engine not running, the suspension
height can only be lowered.
Notice
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Pre-programmed settings
Adjusts the suspension height to one
of three pre-programmed positions.l:lowered positionk:normal positionj:raised positionCaution
If an obstacle is detected while
raising or lowering, the
suspension height is returned to the normal position after a delay.
This does not guarantee damage-
free operation. Ensuring sufficient
clearance and freedom from
obstacles is the responsibility of the driver.
Manual settings
Manual adjustment can only be
performed when the vehicle is
stationary.
Select by pressing h for 2 seconds,
then R to raise, or S to lower.
To exit, press any of the pre-
programmed buttons.

Fault
If the system detects an operating fault, control indicator Õ illuminates
together with A and a warning
chime. Seek the assistance of a
workshop immediately.
Depending on version, a
corresponding message may also
appear in the DIC 3 89.

132Driving and operatingwarning may sound as a signal to
depress the brake pedal or apply the
parking brake.
Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the brake pedal has not
been depressed.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect,
select a lower gear in good time when
driving downhill.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.
Parking
Apply the parking brake. The most
recently engaged gear (see
transmission display) remains
engaged. With N, no gear is engaged.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the
parking brake has not been applied, a
warning chime will sound upon
opening the driver's door.
Manual mode If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, theshift is not executed. This prevents
the engine from running at too low or too high an engine speed.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.

134Driving and operatingInterruption of power supplyThe clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 188.
If the cause of the fault is not a
discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the
drive wheels raised off the ground
3 190.
Towing the vehicle 3 190.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 you depress the
brake pedal firmly. You need to use
considerably more force 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 85.
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.
Control indicator u 3 86.
Fault
If control indicators u and A
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre (DIC), there is a fault in the ABS. The brake system
remains operational but without ABS
regulation.

Driving and operating1359Warning
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.
If control indicators u, A , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
DIC. Seek the assistance of a
workshop.
Have the cause of the fault remedied by a workshop.
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
brake pedal at the same time.
Control indicator R 3 85.

Retractable parking brake
Depending on vehicle, the parking
brake lever retracts to the horizontal
position even with the parking brake
applied.
To release the parking brake, pull the lever up slightly, press the release
button and return the lever to the
horizontal position.
To apply the parking brake, pull the
lever up and release it. The lever rests
in a horizontal position.
