If the lever is in position N, select
another gear, otherwise release the brake pedal or move the lever to +, –
or R to enable an automatic restart.
When one of the following conditions
occurs during an Autostop, the
engine will need to be restarted
manually using the key.
■ the driver's seat belt is unfastened and the driver's door is opened
■ three minutes have elapsed since the engine was switched off
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart may be noticeable.Parking
■ 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. Apply manual parking brake without
pressing release button. Apply as
firmly as possible on downhill or uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.

The driver will be alerted to an
incorrect gear selection by an audible warning chime in conjunction with a
message in the Driver Information
Centre 3 79. The system will
downshift, selecting the most
appropriate gear automatically.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the foot brake is released. To
start off quickly, release the foot brake
and accelerate immediately after
engaging a gear.
Move the selector lever towards A/M
to engage automatic mode; the
transmission shifts to other gears
automatically, dependent on driving
conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
Stopping the vehicle
In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped. In R, reverse gear remains engaged.
When stopping on gradients, engage parking brake or depress the foot
brake. To prevent overheating of the
clutch, an intermittent audible
warning chime may sound as a signal
to depress the foot brake or apply the
parking brake.
Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.

110Driving and operating
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the foot brake 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 engine speed is too low, the
transmission automatically shifts to a
lower gear.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions. If engine
speed is too high, the transmission
only switches to a higher gear via
kickdown.
Kickdown 3 111.

Driving and operating111Electronic driving
programmes
Eco mode E
When automatic mode is engaged,
the Eco mode can be selected to
reduce fuel consumption.
Eco mode selects the most suitable gear depending on the speed of the
vehicle, the engine speed and the
intensity with which the accelerator is pressed.
Activation
Press the E button on the selector
lever housing. Control indicator E is
shown in the transmission display to
indicate activation.
Deactivation
Eco mode is switched off by:
■ pressing the E button again,
■ switching to manual mode.
In order to protect the transmission at
extremely high clutch temperatures,
an intermittent audible warning chime may sound. In such cases, depress
the foot brake, select N and apply the
parking brake to allow the clutch to
cool down.
Kickdown
If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear
depending on engine speed. Full
engine power is available for
acceleration.If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault In the event of a fault, control indicator
Ñ is shown in the transmission
display.
Continued driving is possible,
provided the vehicle is driven with
care and anticipation. A warning
message may appear in the Driver
Information Centre in conjunction with
a warning chime 3 85.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 79.
Have the cause of the fault remedied
by a workshop.

112Driving 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 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 74.
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 75.
Fault9 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 nolonger 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.

Driving and operating113
To release the parking brake, pull thelever 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.
A warning chime will sound if a certain speed is exceeded with the parking
brake applied.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 79.
Control indicator R 3 74.
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
soon as the vehicle begins to
accelerate.
If control indicator Z illuminates
while driving, there is a fault in the Hill
start assist 3 75 . Seek the assistance
of a workshop to have the fault
remedied.
The Hill start assist is not active
during an Autostop.
Stop-start system 3 103.Ride control systems
Traction Control system
The Anti-Slip Regulator (ASR) is a
component of the Electronic Stability
Program (ESP).
ASR 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.
ASR is operational as soon as the
control indicator x extinguishes.
When ASR is active, control indicator x flashes.

114Driving and operating9Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Deactivation
ASR can be switched off when
spinning of drive wheels is required:
press button ASR OFF briefly.
LED in button illuminates and a
message appears in the Driver
Information Centre.
ASR is reactivated by pressing the
ASR OFF button again.
ASR is also reactivated the next time
the ignition is switched on.
Fault ASR will switch off automatically in
the event of a fault. Control indicator
x will illuminate in the instrument
cluster in conjunction with a message
in the Driver Information Centre 3 79.

Control indicator x 3 76.
Electronic stability
program
Electronic Stability Program (ESP)
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. Thisconsiderably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP is operational as soon as control
indicator x extinguishes.
When ESP comes into action, control indicator x flashes.
The ESP system is automatically
activated when the vehicle is started
and cannot be deactivated9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Fault
In the event of a fault, ESP will be
automatically switched off and control
indicator x will illuminate in the
instrument cluster in conjunction with
a message in the Driver Information
Centre 3 79. The LED in the ASR
OFF button will also illuminate.

Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper.
