low or too high (e.g. below 0 °C
or above 35 °C)
● the brake vacuum is sufficient
● the defrosting function is not activated 3 105
● the self-cleaning function of the diesel particle filter is not active
3 122
● the Antilock brake system (ABS) 3 129, Traction Control system
(TC) 3 130 and ElectronicStability Program (ESP® Plus
)
3 131 ride control systems are
not actively engaged
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
" Climate control " chapter for further
information 3 105
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
Notice
If any gear is selected, the clutch pedal must be fully depressed to
restart the engine.
Control indicator Ï 3 89 extinguishes
in the instrument cluster when the engine is restarted.
Restart of the engine by the stop- start system
The selector lever must be in neutral
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:
● the stop-start system is manually
deactivated
● the bonnet is opened
● the vehicle battery is discharged
● the engine temperature is too low
● the brake vacuum is not sufficient
● the vehicle starts to move
● the defrosting function is activated 3 105
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during engine restart may be
noticeable.
Fault
If a fault occurs in the stop-start
system, the LED in Î illuminates,
and a corresponding message
appears in the DIC 3 90. Seek the
assistance of a workshop.

Warning chimes 3 92.
122Driving and operatingParking9Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress foot brake at the same time to reduce
operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards the kerb.
● Lock the vehicle 3 23
● Activate the anti-theft locking system 3 33 and anti-theft alarm
system 3 35.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.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
128Driving and operatingManual transmission
To engage reverse, with the vehicle
stationary depress the clutch pedal, pull up the collar on the selector lever
and engage the gear against the
resistance.
If the gear does not engage, set the
lever in neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch pedal completely. Do not use the
pedal as a foot rest.
Caution
It is inadvisable to drive with hand
resting on the selector lever.
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.
If control indicator R illuminates in
the instrument cluster while driving
and a corresponding message
appears in the Driver Information
Centre (DIC) 3 90, there is a fault in
the braking system. Seek the
assistance of a workshop
immediately.
Driving and operating129Control indicator R 3 86.
Vehicle messages 3 91.
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.
Fault
If control indicator u does not go out
a few seconds after the ignition is switched on, or if it illuminates whiledriving, there is a fault in the ABS.
Control indicator F 3 86 may also
illuminate in the instrument cluster together with a corresponding
message in the Driver Information
Centre (DIC). The brake system
remains operational but without ABS
regulation.9 Warning
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, F , R 3 86
and C 3 86 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the DIC 3 90. Have the
cause of the fault remedied by a
workshop.
Vehicle messages 3 91.
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.
130Driving and operatingControl indicator R 3 86.
Parking 3 122.
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.
Brake assist is not available during an
Autostop.
Stop-start system 3 119.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain onfor a further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the brake
pedal to prevent the vehicle from
rolling forwards or backwards.
The Hill start assist is not active
during an Autostop. Stop-start system
3 119.
Ride control systems
Traction Control system The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
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 as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster. A corresponding message also appears in the Driver
Information Centre (DIC) 3 90.
When TC is active b flashes.

Enhanced Traction function
If necessary, in the event of soft
ground, mud or snow-covered road
surfaces, the Traction control system
(TC) can be deactivated to enhance
traction:
Press Ø on the instrument panel.
Control indicator Ø illuminates in the
instrument cluster and a
corresponding message appears in
the DIC 3 90.
When vehicle speed reaches 30 mph, the system switches
automatically from Enhanced
Traction function to TC operation.
Control indicator Ø extinguishes in
the instrument cluster.
TC is reactivated by pressing Ø
again. Control indicator Ø
extinguishes.
TC is also reactivated the next time
the ignition is switched on.
Fault
If the system detects a fault, control indicator b 3 87 illuminates together
with F 3 86 in the instrument cluster
and a corresponding message
appears in the DIC 3 90.
TC is not operational. Have the cause of the fault remedied by a workshop.
Vehicle messages 3 91.
Electronic stability program The Electronic Stability Program
(ESP® Plus
) improves driving stability
when necessary, regardless of the
type of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This

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 20 mph and
above. Deviations from the stored
speeds may occur when driving uphill or downhill.
