Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a discs by braking firmly a few times at a moderately high speed. Only do this
without endangering vehicles behind you or any other road users Ÿ.
Faults in the brake system
During braking, if you notice that the vehicle does not react as usual (that the
braking distance has increased suddenly) it may be possible that there is a
fault in the braking system. The
H warning lamp lights up and a text
message displayed. Take the vehicle to a qualified workshop immediately
and have the fault repaired. Drive at a moderate speed and be prepared to
use more pressure on the brake pedal, and allow for longer stopping
distances.
Brake servo
The brake servo only operates when the engine is running and the pressure
applied by the driver on the brake pedal increases.
If the brake servo does not operate or the vehicle must be towed, then the
brake pedal will have to be pressed with more force given that the braking
distance will be increased when the brake servo does not operate Ÿ.
WARNING
New brake pads do not brake to full efficiency.
xFor the first 320 km (200 miles), new brake pads have not yet reached
their maximum braking capacity, and need to be run in first. For this, to
compensate for reduced braking efficiency the brake pedal will have to be
pressed with more force.
xTo avoid losing control of the vehicle and causing serious accidents,
always take great care when driving with new brake pads.
xWhen running in new brake pads, always respect the safety distances
between you and other vehicles and do not cause situations requiring
extreme braking performance.
WARNING
When brakes overheat, braking is less efficient and braking distances
increase.
xWhen driving on slopes, brakes can be overloaded and overheat
quickly.
xReduce speed, move down a gear or select a shorter range of gears
before long steep slopes. This allows you to use the engine braking effect
and to reduce the strain on the brake system.
xNon-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat.
WARNING
Wet, frozen or salt-covered brakes take time to brake and this increases
braking distances.
xTest the brakes carefully.
xDry the brakes, free them of ice and salt by braking gently several
times, when weather, road and traffic conditions permit.
WARNING
Driving without the brake servo may significantly increase the braking
distance and result in a severe accident.
xNever allow the vehicle to move forwards when the engine is switched
off.
xIf the brake servo does not operate or the vehicle must be towed, then
the brake pedal will have to be pressed with more force given that the
braking distance will be increased when the brake servo does not operate.

Parking sensor system*
The parking sensor system assists the driver when parking. If the vehicle is
approaching an obstacle, an intermittent sound signal is emitted. The shorter the distance, the shorter the intervals between tones. If the vehicle is too
close to the obstacle, the sound signal becomes constant.
Switching the parking sensor system on and off
xPress the button Ÿfig. 148 when the ignition is switched on.
xAutomatic on: select reverse gear.
xAutomatic off: drive faster than 15 km/h.
The button lights up when the function is switched on.
Things to note regarding the parking sensor system
xThe parking sensor system sometimes registers water on the sensors as
an obstacle.
xIf the distance does not change, the warning signal will sound less loudly
after a few seconds. If the continuous signal sounds, the volume will remain
constant.
xWhen the vehicle moves away from the obstacle, the beeping sound auto-
matically switches off. On approaching the obstacle again, the beeping
sound will automatically switch back on.
xIf the electronic parking brake is engaged or the gear lever is set to P, no
sound will be emitted.
xYour Authorised Service Centre can adjust the volume of the warning
signals.
Note
If the parking sensor system is faulty, a constant acoustic signal will be
emitted the first time it is switched on and the button will flash. Switch the
parking sensor system off using the button and take the vehicle to a
specialist workshop to have the system checked as soon as possible.

Warning and control lamp
Fig. 158 Dash panel display: CCS status indications.
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.
Display
There are different versions of the cruise control system. In vehicles with the
multifunction display (MFI), the set speed is displayed on the instrument
panel screen.Status fig. 158:
CCS temporarily switched off. The set speed is displayed in small figures.
System error. Contact a specialist workshop.
CCS switched on. The speed memory is empty.
The CCS is switched on. The set speed is displayed in large figures.
WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
xNever ignore the warning lamps or text messages.
xStop the vehicle safely as soon as possible.
Caution
Failure to heed the warning lamps and text messages when they appear may
result in faults in the vehicle.

Elements of the tyre monitoring indicatorControl lamp
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.
WARNING
When the tyres are inflated at different pressures or at a pressure that is
too low then a tyre may the damaged resulting in a loss of control of the
vehicle and a serious or mortal accident.
xIf the indicator ~ lights, stop immediately and check the tyres.
xIf the tyres are inflated at different pressures or if a tyre pressure is too
low, this will increase tyre wear, negatively affecting vehicle stability and
increasing braking distances.

Possible cause ŸSolution
~
The tyre pressure of a wheel
has dropped considerably in
relation to the pressure set by
the driver Ÿpage 248.
› Stop the vehicle! Reduce your
speed immediately! Stop the
vehicle safely as soon as possi-
ble. Avoid sudden manoeuvres
and braking!
Check all tyres and pressures.
Replace any damaged tyres.
~System malfunction.
Consult a specialist workshop if
the tyre pressure is correct and
the lamp remains lit after switch-
ing the ignition off and back on
again. Have the system checked
there.
