2015 MERCEDES-BENZ G-Class spare tire

R
Ensure that the wheels are in contact with
the ground at all times.
R Drive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R Check the depth of water before fording
rivers and streams.
R When fording, do not stop and do not
switch off the engine.
R Look out for obstacles, such as rocks,
holes, tree stumps and furrows.
R Always keep the doors, rear door, side win-
dows and the sliding sunroof closed while
the vehicle is in motion.
R Switch off cruise control.
R Do not stray from marked routes or paths.
R Adapt your speed to the terrain. The
rougher, steeper or more ruts on the ter-
rain, the slower your speed should be.
R Drive slowly and at an even speed through
the water. Ensure that a bow wave does not form as you drive.
R On sand, drive quickly to overcome the roll-
ing resistance. Otherwise the vehicle's
wheels could become stuck in loose
ground.
R Do not jump with the vehicle as this will
interrupt the vehicle's propulsion.
R Avoid high engine speeds. Drive at appro-
priate engine speeds (maximum
3,000 rpm).
R Do not shift the automatic transmission to
transmission position N.
R Always check the vehicle for damage after
off-road driving.
i Information about retrofitting special all-
terrain tires is available from any qualified
specialist workshop.
i Do not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra- dients or on slippery or loose surfaces. The
HOLD function cannot hold the vehicle on
such surfaces. Checklist before driving off-road !
If the engine oil warning lamp lights up
while the vehicle is in motion, stop the vehi- cle in a safe place as soon as possible.
Check the engine oil level. The engine oil
warning lamp warning must not be ignored.
Continuing the journey while the symbol is
displayed could lead to engine damage.
X Oil level: check the engine oil level and add
oil if necessary.
Only then does the engine receive enough
oil when the vehicle is on a steep incline.
X Tire-changing tool kit: check that the jack
is working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
X Wheels and tires: check the tire tread
depth and tire pressure.

replace the flat tire with your spare wheel, or
consult a qualified specialist workshop.
Contact an authorized Mercedes-Benz Center if you require information on tested and rec- ommended wheels and tires for summer and
winter driving. Advice on purchasing and car-
ing for tires is also available there.
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair the operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and ask about:
R suitability
R legal stipulations
R factory recommendations

Notes on driving
If the vehicle is heavily loaded, check the tire pressures and correct them if necessary.
When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Oth-
erwise, the tires, particularly the sidewalls,
may be damaged. 306
OperationWheels and tires

Regular checking of wheels and tires
G
WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
R Regularly check the wheels and tires of
your vehicle for damage at least once a
month, as well as after driving off-road or
on rough roads. Damage includes bulges
and deformation on tires, cuts, punctures,
cracks or severe corrosion on wheels, for
example. Damaged wheels can cause a
loss of tire pressure.
R Regularly check the tire tread depth and
the condition of the tread across the whole
width of the tire (Y page 307). In order to
inspect the inner side of the tire surface,
turn the steering wheel to full lock.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do notinstall anything onto the valve other than
the standard valve cap or a valve cap
approved by Mercedes-Benz for your vehi-
cle.
Do not install anything onto the valve, such as tire pressure monitoring systems.
R You should regularly check the pressure of
all your tires including the spare wheel, par- ticularly prior to long trips. Adjust the tire
pressure as necessary (Y page 314).
The service life of tires depends, among other things, on the following factors:
R Driving style
R Tire pressure
R Distance covered Tire tread
G
WARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
R Summer tires: âin (3 mm)
R M+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached. Marking
:shows the tread wear indicator
(TWI). The arrow indicates the placement of
the tire tread.
Do not drive with tires which have too little
tread depth. tire traction on wet road surfaces decreases significantly when the tread depth
is less than 1
/ 8 in (3 mm).
Treadwear indicators (TWI) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth is
approximately 1
/ 16 in (1.6 mm). If this is the
case, the tire is so worn that it must be
replaced.
The recommended tread depth for summer
tires is at least 1
/ 8 in (3 mm). The recommen-
ded tread depth for winter tires is at least 1
/ 6
in (4 mm). Operation
307Wheels and tires Z

Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only mount approved tires of the correct
size onto the wheels.
R Tires are supplied with a protective layer
from the factory. Break in new tires at mod-
erate speeds for the first 60 miles
(100 km). They only reach their full per-
formance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the lat-
est, regardless of wear. This also applies to the spare wheel. Winter operation
General notes
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 327). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and braking power. Change the tires on your vehi-cle to M+S tires. Using summer tires at very
cold temperatures could cause cracks to
form, thereby damaging the tires perma-
nently. Mercedes-Benz cannot accept
responsibility for this type of damage. M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident. M+S tires with a tread depth of less than
ãin
(4 mm) must be replaced immediately. G
WARNING
Wheel and tire dimensions as well as the type of tire can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is mounted, driving characteristics may be severely affected. There is a risk of an acci-
dent.
In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
R never mount more than one spare wheel
that differs from the wheel to be replaced.
R only use a spare wheel that differs from the
wheel to be replaced for a short time.
R do not deactivate ESP ®
.
R have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type.
Do not exceed a maximum speed of 50 mph
(80 km/h) if a spare wheel of a different size is installed.
At temperatures below 45 ‡ (+7 †), use all-
season tires or winter tires. Both types of tire
are identified by the M+S marking.
Not all tires with the M+S marking provide the
driving characteristics of winter tires. In addi-
tion to the M+S marking, winter tires also
have the isnowflake symbol on the tire
wall. Tires with this marking fulfill the require-
ments of the Rubber Manufacturers Associa-
tion (RMA) and the Rubber Association of
Canada (RAC) regarding snow traction, and
were specially developed for driving on snow.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter, since these tires have been
designed specifically for driving on snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling charac-
teristics. 308
Winter operationWheels and tires

Always observe the maximum permissible
speed specified for the M+S tire s you have
mounted.
When you have mounted the M+S tires:
X Check the tire pressures (Y page 309).
X Restart the tire pressure monitor
(Y page 315).
i You can obtain information about winter
tires that have been approved by
Mercedes-Benz especially for your vehicle
at any Mercedes-Benz Service center.
i For further information about tires, see
(Y page 333). Snow chains
! Information about the use of snow chain
compatible AMG winter tires is applicable
for AMG tires. Use of snow chains is only
permissible with these tires.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
! If snow chains are mounted on the front
wheels, the snow chains could grind
against the bodywork or components of the chassis. This could result in damage to the
vehicle or the tires.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle by Mercedes-Benz, or are of a corresponding
standard of quality.
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi- ble when you come to a road that is not
snow-covered.
R Local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to mount snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
If you intend to mount snow chains, please
bear the following points in mind:
R Snow chains cannot be mounted on all
wheel/tire combinations (Y page 331).
R Mount snow chains only in pairs and only
on the rear wheels. Observe the manufac-
turer's mounting instructions.
i You can deactivate ESP ®
(Y page 63)
when pulling away with snow chains instal-
led. You can thereby allow the wheels to
spin in a controlled manner, achieving an
increased driving force (cutting action). Tire pressure

WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
