Stop-start system 3 111.Ride control systems
Traction Control system
The Traction control system (TC) is a
component part of the Electronic
stability program (ESP® Plus
) which
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 as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster.

vehicle and obstacles. It is the driver,
however, who bears full responsibility for the parking manoeuvre.
The system consists of four ultrasonic
parking sensors in the rear bumper.
Notice
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic alarm.
An obstacle is indicated by buzzers.
The interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 1 ft, the buzzer is continuous.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the sensor can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
