2017 MERCEDES-BENZ G-Class inflation pressure

Drivingwiths ummer tires
At temperature sbelo w45‡( +7 †), elasticity in
summe rtires is significantly lower and thus also
traction and braking power. Change the tires on
you rvehicle to M+S tires .Using summe rtires at
very cold temperatures coul dcause cracks to
form, therebyd amaging the tires permanently.
Mercedes-Benz cannot accep tresponsibility for
this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss.Asar esult, you couldlose control of
you rvehicle. There is arisk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã in (4 mm )are not suitabl efor use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
GWARNING
Wheela nd tire dimensions as wel lasthe 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 arisk of an acci-
dent.
In order to reduce risks:
Ryou should thereforea dapt yourdriving
styl eand drive carefully.
Rnever mount more than one spare wheel
that differs from the wheel to be replaced.
Ronly use aspare wheel that differs from the
wheel to be replaced for ashort time.
Rdo not deactivate ESP®.
Rhave aspare wheel that differs from the
wheel that has beenc hangedreplaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as wel lasthe wheel type.
Do not exceed amaximu mspeedof50m ph
(80 km/h) if aspare wheel of adifferent size is
installed.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both type softire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibleg rip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e257).
XRestart the tire pressure monitor
(Ypag e259).
Snowc hains
GWARNING
If you drive too fast with snow chains moun-
ted, they may snap. As aresult, you could
injure others and damage the vehicle. There is
ar isk of an accident.
Observe the maximu mpermissible speedf or
operation with snow chains.
!Information about the use of snow chain
compatibleA MG winter tires is applicable for
AMG tires. Use of snow chains is only per-
missible with these tires.
!On some tire sizes there is not enoug hspace
for snow chains. To avoi ddamage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" section unde r"Tires and wheels".

!Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
Rwheel
Rwheel housing
Rwheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been speciallya pproved for your vehicle by
Mercedes-Benz,ora re ofacorresponding
standard of quality. For more information,
please contact aqualified specialist workshop.
If you intend to mount snow chains, please bear
the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Observe the infor-
mation regarding permitted wheel/tire com-
binations (
Ypage 273).
RInstall the snow chains on all four wheels for
maximum tractive power and driving stability.
If you only have two snow chains, install these
as ap air on the rear wheels. The vehicle then
remains more stable under braking.
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to aroad that is not snow-covered.
RLocal regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
You may wish to deactivate ESP
®when pulling
awayw ith snow chains installed (Ypage 59).
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv- ing force (cutting action).
Tire pressure
Tire pressure specifications
Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning along journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here are
examples. Tire pressure specifications are vehi-
cle-specific and may deviate from the data
shown here. The tire pressure specifications
that are valid for your vehicle can be found on
the Tire and Loading Information placard and
tire pressure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factory can be found on the
labelsd escribed here.
Operation with atrailer: the applicable value
for the rear axle is the maximum tire pressure
value stated in the table inside the fuel filler flap.
Further information on tire pressures can be
obtained at aqualified specialist workshop.
