2005 MERCEDES-BENZ G500 radiator

230 OperationDriving instructionsReturning from off-road drivingOff-road driving increases strain on the ve-
hicle.
We recommend that you inspect the vehi-
cle for possible damage after each off-road
trip. Recognizing any damage and a subse-
quent timely repair reduces the chance of
a possible breakdown or accident later on.
Proceed as follows:


Switch the transfer case in position
HIGH (
page 154).


Disengage differential locks
(page 159).


Remove excessive dirt from tires,
wheels, wheel housings, and under-
body.
For instance, after driving in mud, clean
the radiator, chassis, engine, brakes,
and wheels from extreme dirt using a
strong jet of water.


Inspect frame, oil pan, brake hoses,
etc., as well as vehicle underbody for
possible damage.


Check tires for possible damage and
remove foreign objects. Clean all exte-
rior lamps and conduct a brake test.
Warning!
G
Never drive on pavement with activated dif-
ferential locks. Engaged front axle differen-
tial locks limits ability to move around
curves.
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the roadway.
Inspect the tires and under the vehicle for
possible damage. If the vehicle or tires ap-
pear unsafe, have it towed to the nearest
Mercedes-Benz Light Truck Center or tire
dealer for repairs.
Damage to the vehicle negatively influences
driving comfort and poses the risk of acci-
dent to you and other drivers.

356 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment. This method is pref-
erable to other types of towing.
When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the ground only so far as necessary to have the
vehicle moved to a safe location where the
recommended towing methods can be em-
ployed.
!Use flatbed or wheel lift/dolly equip-
ment, with SmartKey in starter switch
turned to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts. Use the towing eyes.
Switch off the ESP (
page 86),
tow-away alarm (
page 89) and the
automatic central locking
(
page 141).
!When towing the vehicle with all wheels
on the ground, the gear selector lever
must be in position N and the
SmartKey must be in starter switch
position2.
When towing the vehicle with all wheels
on the ground, the vehicle may be
towed only for distances up to 30 miles
(50 km) and at a speed not to exceed
30 mph (50 km/h).
If the vehicle is towed with one axle
raised (observe instructions regarding
flexible drive shaft and propeller
shafts), the engine must be shut off
(SmartKey in starter switch position1).
Otherwise, the 4-ETS may become en-
gaged which may cause loss of towing
control.
!Do not tow-start the vehicle.Warning!
G
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in the starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
Always tow with a tow bar if:

the engine will not run


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
