Wiping with washer fluid X
Press the combination switch beyond the
pressure point in the direction of arrow
2.
i Wipe the windscreen using washer fluid
even if it is raining. By doing so, you will
avoid smearing the windscreen.
Intermittent wipe/rain sensor X
Turn the combination switch in the direc-
tion of arrow 1to position I.
The rain sensor is activated. The appropri-
ate wiping frequency is set automatically
according to the intensity of the rain.
i If you have selected the intermittent wipe
setting, wiping is interrupted when the
vehicle is stationary and you open the driv-
er's or the front-passenger door. This pro-
tects people getting into and out of the
vehicle from being sprayed with water.
Intermittent wipe continues when:
R you close the doors again
R you turn the combination switch to posi-
tion IIor III

Starting the engine X
Apply the parking brake.
X To start a petrol engine: turn the key to
position 3in the ignition lock (Y page 59)
and release it as soon as the engine is run-
ning.
X To start a diesel engine: turn the key to
position 2in the ignition lock .
The q preglow indicator lamp in the
instrument cluster lights up.
X When the qpreglow indicator lamp
goes out, turn the key to position 3and
release it as soon as the engine is running.
i You can start the engine without preglow
if the engine is warm. Pulling away
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift into reverse gear when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train.
i It is only possible to move the selector
lever to the desired position if you depress
the brake pedal. Only then is the selector
lever lock released.
X Depress the brake pedal and hold it down.
X Release the parking brake.
X Move the selector lever to position Dor R.
i Wait until the shift process is completed
before pulling away.
X Release the brake pedal.
X Carefully depress the accelerator pedal.
i Upshifts take place at higher engine
speeds after a cold start. This helps the catalytic converter to reach its operating
temperature more quickly.
AAS (Start-off Assist) AAS helps you when pulling away on uphill
gradients. It holds the vehicle for a short time
after you have removed your foot from the
brake pedal. This gives you enough time to
move your foot from the brake pedal to the
accelerator pedal and depress it before the
vehicle begins to roll back. G
Risk of accident
Never leave the vehicle when it is held by
start-off assist. After approximately one
second, AAS stops holding your vehicle and
it could roll away.
X Depress the brake pedal.
X Pull away.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
AAS does not function if:
R you are pulling away on a level road or a
downhill gradient
R the selector lever is in the Nposition 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

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

Risk of fire and poisoning
The operation of the auxiliary heating pro-
duces hot, toxic exhaust fumes. The fuel
vapours produced during refuelling could
ignite on the hot exhaust system.

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-

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

Driving sys
tems 116 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. G
Risk of accident
Variable Speedtronic is only an aid
designed to assist driving. You are respon-
sible for the vehicle's speed and for braking
in good time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
You can operate cruise control and variable
Speedtronic with the cruise control lever.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R LIM indicator lamp off: Cruise control is selected.
R LIM indicator lamp lit:
Variable Speedtronic is selected.
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. 1

not always maintain the stored speed. You will hear a warning tone if the stored
speed is exceeded. You will see the message
Limit exceeded orLimit in the multi-func-
tion display (G 320 CDI).
X If necessary, apply the brakes.
Selecting variable Speedtronic X
Check whether LIM indicator lamp 2is on.
