Driving systems
Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R
Cruise control* and Speedtronic*, which
are used to control the speed of the vehicle
R
Parktronic* and active parking assist*,
which can help you to find a parking space,
to manoeuvre and park
R
ECO Start-Stop function*, helps you to
save fuel
The ABS, BAS, adaptive brake lights, ESP
®
and STEER CONTROL driving safety systems
are described in the "Driving safety systems"
section (
Y
page 55).
Cruise control*
Cruise control maintains a constant road
speed for you. You must select a low gear in
good time on long and steep downhill gradi-
ents, especially if the vehicle is laden or tow-
ing a trailer. By doing so you will make use of
the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely.
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h.
G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time.
G
Risk of accident
Do not use cruise control:
R
in road and traffic conditions which do
not allow you to maintain a constant
speed (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
R
on slippery roads. Braking or accelerat-
ing could cause the drive wheels to lose
traction and the vehicle could then skid.
R
when there is poor visibility, e.g. due to
fog, heavy rain or snow
Cruise control lever
You can operate cruise control and variable
Speedtronic with the cruise control lever.
Controls
* optional
