152Driving and operatingElectronic drivingprogrammes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission control
enables the driver to select
manually first, second or third gear for starting off.
Kickdown
If the accelerator pedal is pressed
down completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.Fault
In the event of a fault a message is
displayed in the Driver Information
Centre. Vehicle messages 3 104.
Electronic transmission control
enables only fourth gear. The
transmission no longer shifts
automatically.
Have the cause of the fault remedied
by a workshop.
Interruption of power supply
In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position. The ignition key cannot be
removed from the ignition switch.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 232.
If the vehicle battery is not the cause
of the fault, release the selector lever.
1. Apply the parking brake.
2. Release the selector lever trim from the centre console. Pokewith a finger into the leather
socket below the selector lever
and push the trim upwards.
Rotate trim to the left.
156Driving and operatingIf engine speed is too low, the
transmission automatically shifts to a
lower gear.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Gear shift indication
The symbol R or S with a number
beside is indicated when gearshifting
is recommended for fuel saving
reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.Kickdown
If the accelerator pedal is presseddown completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
Fault
To prevent damage to the manual transmission automated, the clutch is
engaged automatically at high clutch
temperatures.
In the event of a fault, a warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 104.
Continued driving is restricted or not
possible, depending on the fault.
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 beforecontinuing the 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 93.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating159Functionality check
When the vehicle is not moving, the
electric parking brake might be
applied automatically. This is done to
check the system.
Fault
Failure mode of electric parking brake
is indicated by a control indicator j
and by a vehicle message which is
displayed in the Driver Information Centre. Vehicle messages 3 104.
Apply electric parking brake: pull and hold the switch m for more than
five seconds. If control indicator m
illuminates, electric parking brake is
applied.
Release electric parking brake: push and hold the switch m for more than
two seconds. If control indicator m
extinguishes, electric parking brake is
released.
Control indicator m flashes: electric
parking brake is not fully applied or
released. When continuously
flashing, release electric parking
brake and retry applying.Brake assist
If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain
on for further two seconds. The
brakes release automatically as soon
as the vehicle begins to accelerate.Ride control systems
Traction Control systemThe Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC).
TC 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 after each engine
start as soon as the control indicator
b extinguishes.
When TC operates b flashes.
174Driving and operatingAdvanced parking assist9Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 97 or,
depending on the version, on the Info- Display 3 102 , supported by acoustic
signals.
The driver must control acceleration,
braking and gear shifting, while
steering is done automatically.Advanced parking assist is always
combined with front-rear parking
assist. Both systems use the same
sensors in the front and rear bumper.
The system has six ultrasonic parking
sensors each in both the rear and
front bumper.
Activation
Advanced parking assist can only be
activated when driving forwards.When searching for a parking slot, the system is ready to operate with a
short press of (.
The system recognises and
memorises 10 metres for parallel
parking slots or six metres for
perpendicular parking slots in the parking assist mode.
The system can only be activated at
a speed up to 18 mph and the system searches for a parking slot at a speed
up to 18 mph.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres for
parallel parking and 2.5 metres for
perpendicular parking.
