If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact a
workshop immediately.
Malfunction indicator light 3 84.Manual 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.

120Driving and operatingBrakes
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, there is a fault in the braking
system. Seek the assistance of a
workshop immediately.Control indicator R 3 85.
Vehicle messages 3 89.
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 85.
Fault
If control indicator u does not go out
a few seconds after the ignition is
switched on, or if it illuminates while driving, there is a fault in the ABS.
Control indicator F 3 84 may alsoilluminate in the instrument cluster
together with a corresponding
message in the Driver Information
Centre. 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 85
and C 3 84 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the Driver Information
Centre 3 88. Have the cause of the
fault remedied by a workshop.

Driving and operating121Parking brake9Warning
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 85.
Parking 3 117.
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 3 115.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on
for 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 foot
brake to prevent the vehicle from
rolling forwards or backwards.
The Hill start assist is not active
during an Autostop. Stop-start system

122Driving and operatingRide 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 3 88.
When TC is active b flashes.9 Warning

feature tempt you into taking risks

surfaces, the Traction control system
(TC) can be deactivated to enhance
traction:
Press the Ø button on the
instrument panel.
Control indicator Ø illuminates in the
instrument cluster and a

Electronic stability
program
The Electronic Stability Program
(ESP® Plus
) improves driving stability
when necessary, regardless of thetype 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
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP® Plus
is operational as soon as
the ignition is switched on and control

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.
For safety reasons the cruise control cannot be activated until the foot
brake has been operated once.

Do not use the cruise control if it is notadvisable to maintain a constant
speed.
Control indicators U and m 3 87.
Activation
Press switch m, control indicator U
illuminates green in the instrument
cluster.
Cruise control is now in standby mode
and a corresponding message
appears in the Driver Information
Centre.
Accelerate to the desired speed and
press switch < or ]. The current
speed is now stored and maintained and the accelerator pedal can be
released.Control indicator m illuminates green
in the instrument cluster together with
U and a corresponding message
appears in the Driver Information
Centre.
Vehicle speed can be increased by depressing the accelerator pedal.
The stored speed flashes in the
instrument cluster. When the
accelerator pedal is released, the
previously stored speed is resumed.
Cruise control remains activated
while gearshifting.
The speed is saved until the ignition
is switched off.

126Driving and operating
Increase speedWith cruise control active, the vehicle
speed can be increased continuously or in small increments by holding
down or tapping switch < repeatedly.
When the switch is released the
current speed is stored and
maintained.
Alternatively, accelerate to the
desired speed and store by pressing
switch <.
Reduce speed With cruise control active, the vehicle
speed can be decreased
continuously or in small increments
by holding down or tapping switch ]
repeatedly.
When the switch is released the
current speed is stored and
maintained.Deactivation
Press switch §: cruise control is
deactivated and the green control
indicator U extinguishes in the
instrument cluster.
Automatic deactivation: ■ Vehicle speed drops below 20 mph,
■ The brake pedal is depressed,
■ The clutch pedal is depressed,
■ Selector lever in N.
The speed is stored and a
corresponding message appears in
the Driver Information Centre.
Reactivation
Press switch R at a speed above
20 mph.
If the stored speed is much higher
than the current speed, the vehicle
will accelerate powerfully until the
stored speed is obtained.
Pressing switch < will also reactivate
the cruise control function, but at the
current vehicle speed only, not the
stored speed.
Deleting the stored speedPress switch m: Green control
indicators U and m extinguish in the
instrument cluster.
Cruise control speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed above 20 mph.
