2012 MERCEDES-BENZ G-Class wheel

independent of their respective torques.
Keep
in
mind that by engaging the differential
locks, vehicle steerability is severely
restricted.
For your own safety, the safety of others and
to prevent damage to your vehicle, the
differential locks must not be activated on
paved roads. Keep in mind that when driving
on firm road surfaces, the function of the
differentials is necessary and therefore they
must never be locked on firm road surfaces.
The steerability of the vehicle would
otherwise be lost and steering would no
longer be possible. For this reason, the
differential locks must be engaged
exclusively during off-road driving, and only
when activating the other driving systems
(4ETS, ESP ®
and LOW range off-road gear) is
no longer sufficient.
Activating the differential lock General information
G
WARNING
Never drive on firm road surfaces with
differential locks engaged. Never drive on
narrow bends

with front-axle differential locks
engaged. With differential locks engaged, the
vehicle's ability to steer is severely restricted
and the danger of accidents is therefore
higher.
Do not engage or disengage differential locks
while driving on a bend. The vehicle may
otherwise make a jerking movement. You
could thus lose control of the vehicle and
cause an accident.
If you select a differential lock, ABS, 4ETS,
ESP ®
and BAS will be deactivated.
Activate the differential locks:
R off-road

WARNING
A driver's attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when

traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h ), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature
R warning/indicator lamps R
malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired.
If you

must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible. G
WARNING
Malfunction and warning messages are only
displayed for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance services and safety checks
performed on

the vehicle. Bring the vehicle to
an authorized Mercedes-Benz Center to
address the malfunction and warning
messages. Displays and operation
Tachometer
The red

band in the tachometer indicates the
engine's overrevving range.
! Do not drive in the overrevving range, as
this could damage the engine.

WARNING
Driving when your engine is overheated can
cause some

fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening 152

the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other
traffic.
Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
The coolant temperature gauge is in the
instrument cluster on the left-hand side.
Under normal driving conditions, with the
correct anti-corrosion and antifreeze additive
concentration, the reading may rise to
248 ‡(120 †).
! If the coolant temperature exceeds
248 ‡(120 †) do not continue driving. The
engine will otherwise be damaged. Outside temperature display
The outside temperature display is in the
multifunction display (Y

page 154).G
WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point

do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Changes in the outside temperature are
displayed after a short delay. Operating the on-board computer
The on-board computer is activated as soon
as you

turn the SmartKey to position 1 in the
