Malfunction in the radar sensor
If the radar sensor operation is impaired, for
example due to heavy rain, mist, snow or dirt,
the City Safety Assist system function is tem-
porarily switched off. On the instrument pan-
el display the control lamp flashes.
When the fault in the radar sensor has been
rectified, the City Safety Assist system func-
tion automatically becomes available. The
control lamp switches off.
The following conditions could prevent the
City Safety Assist system from functioning:
●
Tight bends.
●
Accelerator pressed all the way down to the
floor.

Driver assistance systems
Hill driving assistant*
Operation
This function is only included in vehicles with
ESC.
The hill driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
●
being on a ramp or hill/slope,
●
doors closed,
●
vehicle completely stationary,
●
engine running and foot on the brake,
●
besides having a gear engaged or being in
neutral for manual gear change and with the
selector lever at positions S, D or R in vehi-
cles with an automatic gearbox.
This system is also active when reversing up-
hill.
WARNING
●
If you do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
If the engine stalls, depress the brake ped-
●
al or use the hand brake immediately.
When following a line of traffic uphill, if you
●
want to prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off.
Note
The Official Service or a specialist workshop
can tell you if your vehicle is equipped with
this system.
