controls the balance between the wheels
and the rear axle.

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

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.
If it is on, variable Speedtronic is already
selected.

Risk of accident
If there is a change of drivers, advise the
new driver of the limit speed stored.

When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. The ultra-
sonic reversing aid does not detect such
objects when they are in the immediate
vicinity of the vehicle. You could damage
the vehicle or the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause the ultra-
sonic reversing aid to malfunction.
Minimum distance Centre Approximately 30 cm
Corners Approximately 30 cm
If there is an obstacle within this range, all
warning displays flash and a warning tone
sounds. If the distance falls below the mini-
mum clearance, it may no longer be shown.
Warning displays
The warning display shows the distance
between the sensors and the obstacle.
Station wagon: the warning display is in the
rear next to the tailgate.
Cabriolet: the warning display is on the front-
passenger side at the top on the roll bar. Example: station wagon
The warning display is divided into four yellow
and two red segments. If you hear a warning
tone and all segments light up briefly, the
ultrasonic reversing aid is operational.
One or more segments light up as the vehicle
approaches an obstacle, depending on the
vehicle's distance to the obstacle.
From the:
R
fourth segment you will hear an intermit-
tent warning tone
R fifth segment you will hear a faster inter-
mittent warning tone
R sixth segment you will hear a very fast inter-
mittent warning tone. You have reached
the minimum distance. Trailer towing The ultrasonic reversing aid is deactivated
when you connect the trailer to your vehicle
electrically.
!
The ultrasonic reversing aid measures
the minimum detection range to an obsta-
cle from the bumper, not the ball coupling
or the spare wheel. Reversing camera* (Station wagon)
The reversing camera is an optical aid. It
shows the area behind your vehicle in the
COMAND APS display. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
