152Driving and operatingHill start assistThe system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
The hill start assist is not active during
an Autostop.Ride control systems
Traction Control system The Traction Control system (TC) is a component of the Electronic Stability
Control (ESC) 3 153.
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.

Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning. ESC operates in
combination with the Traction Control system (TC) 3 152.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.ESC is operational after each engine
start as soon as the control indicator
b extinguishes.

General information
9Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the valid
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. He shall always be ready to take action and apply the
brakes.
System limitations
The system is designed to warn only for vehicles, but may react also on
other objects.
In the following cases, forward
collision alert may not detect a vehicle
ahead or sensor performance is
limited:
● On winding roads.
● When weather limits visibility, e.g. fog, rain, or snow.
● When the sensor is blocked by snow, ice, slush, mud, dirt, or
windscreen damage.
Following distance indication
The following distance indication
displays the distance to a preceding
moving vehicle. The front camera in
the windscreen is used to detect the
distance of a vehicle directly ahead in the vehicle's path. It is active at
speeds above 40 km/h.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 96 . Press
MENU on the turn signal lever to
select Vehicle Information Menu

Driving and operating167
The parking slot suggestion of the
system is accepted when the vehicle is stopped by the driver within
10 metres after the "Stop" message is given. The system calculates the
optimal route into the parking slot. Then it manoeuvres the driver into the
slot by giving detailed instructions.The instructions in the display show:
● A hint when driving faster than 30 km/h.
● The demand to stop the vehicle, when a parking slot is detected.
● The direction of driving during the
parking manoeuvre.
● The steering wheel position during parking.
● For some of the instructions a progress bar is shown.A successful parking manoeuvre is
indicated by the 'End position'
symbol.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than approx. 30 cm.
Changing the parking side
The system is configured to detect parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
indicator to the driver side for the
duration of searching.
