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*, which assists you in parking
and manoeuvring
R reversing camera*, which assists you when
parking and manoeuvring
The ABS, BAS, adaptive brake lights, ESP ®
and EBV (electronic brake-power distribution)
driving safety systems are described in the
"Driving safety systems" section
(Y page 51). Cruise control*
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or3 in good time. 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
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 accelerating
could cause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
Cruise control display in the speedom-
eter (vehicles with the luxury multi-
function steering wheel *,12 buttons) When cruise control is activated, the seg-
ments from the set speed to the maximum
speed light up in the multi-function display.

Storing the current speed or calling up
the last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for the
current driving and traffic situation. Other-
wise, sudden braking could endanger you or
others.
X Briefly pull the cruise control lever towards
you =.
Making fine adjustments in
1 km/hincrements X
Briefly press the cruise control lever to the
pressure point, up :for a higher speed or
down ?for a lower speed.
or
X Keep the cruise control lever pressed to the
pressure point until the desired speed is
set. Press the cruise control lever, up :
for a higher speed or down ?for a lower
speed.

Cruise control* is selected.
Variable Speedtronic is deactivated automat-
ically when you depress the accelerator pedal
beyond the pressure point (kickdown), but
only if your current speed does not differ by
more than 20 km/h from the stored speed.
You will hear a warning tone if this is the case. G
Risk of accident
It is not possible to deactivate variable Speed-
tronic by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent Speedtronic (vehicles with
the luxury multi-function steering
wheel*, 12 buttons) i
Permanent Speedtronic is only available
in certain countries.
You can use the on-board computer to limit
the speed permanently to a value between
160 km/h (e.g. for driving with winter tyres)
and the maximum speed.
Just before the stored speed is reached, it
appears in the multi-function display.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). 112 Driving systemsControls
