Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R Cruise control and variable Speedtronic
which you can use to control the speed of
the vehicle
R Ultrasonic reversing aid*, which helps you
park and manoeuvre
R Reversing camera *,which helps you when
parking and manoeuvring
You will find further information about driving
off-road in the "Operation" section
(Y page 172). Cruise control
Cruise control maintains a constant road
speed for you. On long and steep downhill
gradients, especially if the vehicle is laden or
towing a trailer, you must select shift range
1, 2or 3in 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 Cont

Calling up the last speed stored G
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 Remove your foot from the accelerator
pedal.
Cruise control adjusts the vehicle’s speed
to the last speed stored.
i G 320 CDI: if no speed is stored, cruise
control stores the current speed and main-
tains it.
Setting a speed X
Press the cruise control lever up 1for a
higher speed or down 4for a lower speed.
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.
Making adjustments in 1 km/hincre-
ments X
Briefly press the cruise control lever up
1 for a higher speed or down 4for a
lower speed.
The last speed stored is increased or
reduced.
Deactivating cruise control There are several ways to deactivate cruise
control:
X Briefly press the cruise control lever for-
wards 6.
or
X Brake.
or
X Briefly press the cruise control lever in the
direction of arrow 5.
Variable Speedtronic is selected. LIM indi-
cator lamp 2in the cruise control lever
lights up. Cruise control is automatically deactivated if,
for example:
R
you are driving at less than 30 km/h
R ESP ®
is intervening
R you move the selector lever to Nwhile driv-
ing
R G 320 CDI: you engage a differential lock
i The last speed stored is cleared when you
switch off the engine. Speedtronic
Variable Speedtronic helps you to avoid
exceeding a specified speed, e. g. when driv-
ing through varying speed limits in built-up
areas. On long and steep downhill gradients,
especially if the vehicle is laden or towing a
trailer, you must select shift range 1,2or 3
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

ously while the vehicle is in motion, e.g. Controls

General notes
The vehicle is equipped with the Thermatic
air-conditioning system. Thermatic combines
an automatic heating and ventilation system
with a cooling system.
Thermatic controls the temperature and the
humidity of the vehicle interior and filters out
undesirable substances from the air.
Thermatic is only operational when the
engine is running. Optimum operation is ach-
ieved only when you drive with the side win-
dows and sliding/tilting sunroof* closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 85). This will
speed up the cooling process and the desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and completely filters out pol-
len. A clogged filter reduces the amount of
air supplied to the vehicle interior. For this
reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may obstruct your view
of the traffic situation, thereby causing an
accident. Cont
