Driving safety sys
tems 49R
do not deactivate ESP ®
under any cir-
cumstances.
R only depress the accelerator pedal as far
as necessary when pulling away.
R adapt your driving style to suit the pre-
vailing road and weather conditions.
The vehicle could otherwise go into a skid.
ESP ®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot override
the laws of physics.
! If:
R the vehicle is being towed with the front
or rear axle raised,
R the parking brake is being tested using a
dynamometer,
the ignition must be switched off (key in
position 0or 1in the ignition lock). Other-
wise, application of the brakes by ESP ®
could destroy the brake system on the front
or rear axle.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance. You could otherwise damage the drive train
or the brake system.
i If differential locks are switched on, ABS,
BAS and ESP ®
switch themselves off auto-
matically.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
Activating/deactivating ESP ® ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin. If you deactivate ESP
®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. Spinning of the
wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R and are driving at above 60 km/h, ESP ®
still intervenes when one wheel reaches its
grip limit even though it is switched off.
i If ESP ®
is deactivated and one or more
wheels start to spin, the vwarning lamp
in the instrument cluster flashes. In such
situations ESP ®
will not stabilise the vehi-
cle. Safety

brake, a warning tone will sound. Differential locks
Differential locks improve the vehicle’s trac-
tion.
Your vehicle is equipped with the following:
R A differential lock for the transfer box: this
controls the balance between the front and
rear axles.
R A differential lock for the rear axle: this
controls the balance between the wheels
and the rear axle.
R A differential lock for the front axle: this
controls the balance between the wheels
and the front axle. Controls

In order to avoid damage to the transfer
case, you may only operate the vehicle on
a roller dynamometer (single-axle roller
dynamometer), if:
R the undriven axle is raised
or
R the relevant propeller shaft is disconnec-
ted
and
R the differential lock of the transfer case
is engaged
Engaging the differential locks G
Risk of accident
When driving on a firm road surface, never
drive with the differential locks engaged.
Never drive through tight corners with the
differential lock on the front axle engaged.
When differential locks are engaged, the
vehicle's steerability is greatly impaired
and the risk of accident thereby increases.
Do not engage or disengage the differential
locks while cornering. The vehicle motion
could otherwise be jerky. You could lose
control of the vehicle as a result and cause
an accident. If you select a differential lock, ABS, 4ETS,
ESP
®
and BAS are deactivated.
Engage the differential locks:
R when driving off-road
R to deactivate ABS, 4ETS and ESP ®
when
off-road
R when fording
R on snowy, icy or rough road surfaces
The switches are located in the upper section
of the centre console. 1

Points to remember
You will find an illustration of the instrument
cluster in the "At a glance" section . G
Risk of accident
No further messages can be displayed if the
instrument cluster and/or the multi-func-
tion display fails.
This means that you will not see information
about the driving situation, such as the
speed, outside temperature, warning/indi-
cator lamps, display messages or system
failures. The vehicle's handling character-
istics may be affected. Adjust your driving
style and speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop. 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
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g. Controls
