vehicle is parked if the transmission is still in N.
When the ignition is switched off, the transmission no longer responds to
movement of the selector lever.
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
Driving and operating121speed is too high, the transmission
only switches to a higher gear via
kickdown 3 121.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre 3 83.
Electronic 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 E 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 E 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 brake pedal, 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 geardepending 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 s is shown in the transmission
display.
Continued driving is possible,
provided the vehicle is driven with
care and anticipation. A warning
122Driving and operatingmessage may appear in the Driver
Information Centre in conjunction with
a warning chime 3 93.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 88.
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 82.
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.
Fault
In the event of a fault, control indicator u illuminates in the instrument
cluster. Depending on version, a
corresponding warning message,
e.g. ABS unavailable , may also be
displayed in the Driver Information
Centre 3 88.
Driving and operating1239Warning
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.
Control indicator u 3 82.
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
brake pedal 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 88.
Control indicator R 3 82.
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.
124Driving and operatingHill start assistThe system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal 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 3 83 illuminates
while driving, there is a fault in the Hill
start assist. Depending on version, a
corresponding warning message,
e.g. Hill holder unavailable , may also
be displayed in the Driver Information
Centre 3 88. Seek the assistance of
a workshop to have the fault remedied.
The Hill start assist is not active
during an Autostop.
Stop-start system 3 113.Ride control systems
Traction Control system The Anti-Slip Regulator (ASR) is a
component of the Electronic Stability
Control (ESC).
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.
