Driving and operating107Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Control indicator [ extinguishes
as soon as the self-cleaning
operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 118, 3 164 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Manual transmission
To engage reverse, with the vehicle
stationary, wait 3 seconds after
depressing the clutch pedal, pull up
the collar on the selector lever and
engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not grind the clutch unnecessarily. When operating, depress the clutchpedal completely. Do not use the
pedal as a foot rest.
108Driving and operatingCaution
It is not advisable to drive with thehand resting on the selector lever.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre 3 75.
Manual transmission
automated
The manual transmission automated
(MTA) permits manual (manual
mode) or automatic gear shifting
(automatic mode), both with
automatic clutch control.
Transmission display
Shows the mode and current gear.
Starting the engine Depress the foot brake when starting
the engine.
If the foot brake is not depressed, a
warning message appears in the
Driver Information Centre in
conjuction with a warning chime
3 85 and the engine cannot be
started.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 79.
When the foot brake is depressed, the
transmission automatically shifts to
N (neutral) and the engine can be
started. There may be a slight delay.

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.
