Operation
The City Safety Assist function is limited by
the l
a
w
s of physics and by the nature of the
system itself. For this reason, this may pro-
duce reactions from the City Safety Assist
system in certain circumstances that are late
or unexpected by the driver. For this reason,
always pay due attention and if necessary, in-
tervene.
For example, the following driving situations
require special attention:
Driving through a bend
When entering or leaving a “long” bend, the
vehicle may decelerate when the laser sensor
detects a vehicle travelling in the adjoining
lane ››› Fig. 156 A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehi-
cles in front if they are in the sensor detec-
tion zone ››› Fig. 156 B. This applies especial-
ly to narrow vehicles such as motorbikes.
Other vehicles changing lanes
Vehicles moving into your lane in close prox-
imity can cause unexpected braking from the
City Safety Assist system
›››
Fig. 157. To inter-
rupt deceleration you can accelerate, turn the
steering wheel or press the clutch.
Possible malfunction to the laser sensor
If the laser sensor operation function is im-
paired, for example due to heavy rain, mist,
snow or dirt, the City Safety Assist system
function is temporarily disconnected. On the
instrument panel display the control lamp
flashes.
When the malfunction in the laser sensor has
been rectified, the availability of the City
Safety Assist system function is automatically
restored. 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.
●
If the City Safety Assist system is switched
off or there is a fault ››› page 157.
●
If the laser sensor is dirty, covered or over-
heated ››› page 158.
●
In the event of snow, heavy rain or dense
fog.
●
If there are vehicles in front.
●
Vehicles changing lanes.
●
Vehicles moving in the opposite direction
in the same lane.
●
Very dirty vehicles with a low degree of re-
flection.
●
Pre
sence of thick dust.
Hill driving assistant*
Operation
This function is only included in vehicles with
ESC.
The hil
l 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 f
or 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.
