2008 MERCEDES-BENZ G-CLASS SUV warning light

Tyres and wheels
166 help you decide whether the tyre pressures
should be corrected.
The tyre pressure monitor is not able to
warn you of a sudden loss of pressure, e.g.
if the tyre is penetrated by a foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
i If you are carrying a deflated tyre in the
vehicle, you may only reactivate the tyre
pressure monitor if:
R the deflated tyre is no longer in the vehi-
cle
R you have adjusted the tyre pressure cor-

The standard display appears in the multi-
function display (Y page 100).
X Press the jork button to select the
tyre pressure function on the multi-function
steering wheel. The current tyre pressure for each wheel will
be displayed.
If the vehicle was parked for longer than
20 minutes, the following message appears:
Tyre pressure displayed only after
driving a few mins.

The tyre pressure values indicated by the
on-board computer may differ from those measured at a filling station with a pressure
gauge. The on-board computer will gener-
ally give a more accurate value.
Tyre pressure warning If the tyre pressure on one or more wheels
drops significantly, the following message
appears in the multi-function display:
The tyre pressure of the affected wheel(s) will
be displayed in a red rectangle. You will also
hear a warning tone.

Winter driving

!
On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
i Vehicles with a tyre pressure monitor*
If the positions of the wheels on the vehicle
are changed, the tyre pressure may be tem-
porarily displayed at the wrong position.
This is rectified after a few minutes of driv-
ing; the tyre pressures are then displayed
for the correct positions. Winter driving
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter. Winter tyres
Use winter tyres at temperatures below +7 °C
and on snow or ice-covered roads. Only then
can the effect of the ABS, BAS, 4ETS and
ESP ®
driving systems also be ensured in win-
ter.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with a tread depth of less than
4 mm must be replaced immediately. They
are no longer suitable for winter use and
can no longer provide sufficient grip. This
could cause you to lose control of your
vehicle and cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that of the vehicle, affix an appropriate warning
sign in the driver's field of vision. This can be
obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
Once you have fitted the winter tyres:
X
Check the tyre pressures (Y page 164).
X Restart the tyre pressure moni-
tor* (Y page 166). G
Risk of accident
If you fit the spare wheel when driving with
winter tyres, bear in mind that driving sta-
bility will be impaired due to unstable cor-
nering characteristics caused by the differ-
ent tyres. Therefore, you should adapt your
driving style and drive even more carefully.
Have the spare wheel replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop. Operation

R
Follow the line of fall when driving on slopes
and steep gradients.
R Before driving on extreme uphill and down-
hill gradients, shift the transfer case to
LOW (Ypage 92).
R Engage the differential locks, if necessary
(Y page 94).
R Observe the warnings for off-road driving
(Y page 172).
R Drive slowly.
R Accelerate gently and make sure that the
wheels are gripping.
R Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance. R
Select a shift range appropriate to the gra-
dient.
R Before tackling steep downhill gradients,
select shift range 1.
Maximum gradient-climbing capability On good road surfaces and with the
LOWgear
engaged selected, the maximum gradient-
climbing capability is 80%.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognises this and brakes the
wheels accordingly. The rear wheel torque
is increased and it is easier to pull away.
Brow of hill When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately before reaching the brow of the hill.
Make use of the vehicle’s own impetus to
travel over the brow.
This style of driving prevents:R
the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from travelling too quickly down
the other side
Driving downhill R
Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth-
erwise, the vehicle could slip sideways, tip
and overturn.
R Before tackling steep downhill gradients,
select shift range 1.
This way you use the engine's braking
effect to reduce the speed. If this is not
sufficient, brake gently. When doing so,
make sure that the vehicle is facing in the
direction of the line of fall.
R Check that the brakes are working normally
after a long downhill stretch.

Risk of injury
The jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed.
You must use axle stands if you are carrying
out work on the vehicle.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the tailgate is opened or closed) and you
could be seriously injured.
i Check the expiry date of the first-aid kit
annually, and replace the contents when
necessary. i
When using the jack, you should also
observe the safety notes in the "Flat tyre"
section (Y page 243).
