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 ( Ypage 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

the direction of arrow 5.
LIM indicator lamp 2in the cruise control
lever goes out. Cruise control is selected.
Storing and maintaining the current
speed You can store the current speed if you are
driving faster than 30 km/
h.
X Accelerate the vehicle to the desired
speed.
X Briefly press the cruise control lever up
1 or down 4.
X Remove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill and downhill
gradients. The stored speed is resumed
when the gradient levels out.
Vehicles with manual transmission: When selecting another gear, press the
accelerator pedal slightly to increase the
smoothness of the gear change.
When you depress the clutch pedal and
change to another gear, the engine speed
can increase slightly while no gear is selec-
ted.
R
always drive at adequate, but not exces-
sive, engine speeds.
R change gear in good time.
R if possible, do not change down several
gears at a time.

Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for
the current situation. Otherwise, sudden
acceleration or braking could endanger you
or others.
X Briefly pull the cruise control lever towards
you 3.

X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
i Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
i Vehicles with AUTOTRONIC*:
When you decelerate the vehicle using the
cruise control lever, AUTOTRONIC changes
down if deceleration is insufficient.

four seconds on vehicles with a manual
transmission
R you move the selector lever to Nwhile driv-
ing in vehicles with AUTOTRONIC*

switch off the engine. Speedtronic*
Speedtronic is used to make sure that you do
not exceed a stored speed. You must select
a low gear in good time on long and steep
downhill gradients, especially if the vehicle is
