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

On-board computer
97Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engine when the
red band is reached.
! Do not drive in the overrevving range.
Doing so will damage the engine. H
Environmental note
Avoid driving at high engine speeds, as this
increases your vehicle's consumption
unnecessarily and pollutes the environ-
ment through increased emissions. Outside temperature display
G
Risk of accident
The road surface may be icy, especially in
wooded areas or on bridges, even if tem-
peratures are just above freezing point. The
vehicle could skid if you fail to adapt your
driving style. You should therefore always
adapt your driving style and speed to suit
the weather conditions.
There is a short delay before a change in out-
side temperature is displayed. On-board computer
Points to remember
The on-board computer is activated as soon
as you turn the key to position 1in the ignition
lock. You can use the on-board computer to
call up information relating to your vehicle
and to make and adjust settings.
You can call up the next service due date,
select the display language for the instrument
cluster and set other functions. G
Risk of accident
Only use the on-board computer when road
and traffic conditions permit. You would
otherwise be distracted and unable to con-
centrate properly on driving, and could
cause an accident.
The on-board computer shows information in
the multi-function display. Multi-function steering wheel
You can control the multi-function display and
the settings in the on-board computer with
the buttons on the multi-function steering
wheel. 1
