2015 MERCEDES-BENZ G-Class tire pressure

Deactivating the HOLD function
G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
The HOLD function is deactivated automati-
cally if:
R you accelerate and the transmission is in
position Dor R.
R you shift the transmission to position P.
R you depress the brake pedal again with a
certain amount of pressure until ëdis-
appears from the multifunction display.
R you activate DISTRONIC PLUS.
On steep uphill or downhill gradients or if
there is a malfunction, the transmission may
also be automatically shifted into position P.Permanent all-wheel drive
! Never tow the vehicle with one axle
raised. This may damage the transfer case. Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or
be fully raised. Observe the instructions for
towing the vehicle with all wheels in full
contact with the ground.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of ten seconds) on a brake test dynamometer.
When doing this, turn the SmartKey to posi-
tion 0or 1in the ignition. Failure to do this
can cause damage to the drive train or the brake system.
! A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system.
The all-wheel drive system ensures that all
four wheels are permanently driven. The all-
wheel drive system improves vehicle traction together with ESP ®
and 4ETS if a drive wheel
spins due to insufficient grip.
If a drive wheel spins due to insufficient grip:
R Only depress the accelerator pedal as far as
necessary when pulling away.
R Take your foot off the accelerator, slowly,
while the vehicle is in motion.
The permanent all-wheel drive system can
neither reduce the risk of accident nor over-
ride the laws of physics if you fail to adapt
your driving style or if you are inattentive. The
all-wheel drive system cannot take into
account road, weather or traffic conditions.
The all-wheel drive system is only an aid. You
are responsible for maintaining a safe dis-
tance to the vehicle in front, for vehicle speed, for braking in good time and for staying in
lane.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains (Y page 309). Only in this way can the
maximum effect of all-wheel drive be ach-
ieved.

R
the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When towing a trailer, your vehicle's handling
characteristics will be different in comparison with when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning radius
This could impair the handling characteris-
tics.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion.
General notes R
Do not exceed the legally prescribed max-
imum speed for vehicle/trailer combina-
tions in the relevant country.
This lowers the risk of an accident.
R Only install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized Mercedes-Benz Center.
R The bumpers of your vehicle are not suita-
ble for installing detachable trailer cou-
plings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R If you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to the ball coupling. i
When towing a trailer, set the tire pres-
sure on the rear axle of the towing vehicle
for a maximum load; see the tire pressure
table in the fuel filler flap (Y page 310).
You will find installation dimensions and loads
under "Technical data" (Y page 346).
The maximum noseweight of the trailer draw- bar on the ball coupling for up to 3 people is
562 lbs (255 kg). The maximum noseweight
of the trailer drawbar for more than 3 people and the maximum load for the trunk can be
found in the noseweight table (Y page 347).
However, the actual noseweight must not
exceed the value given on the trailer tow hitch or trailer identification plates. The lowest
weight applies.
Please note that when towing a trailer,
PARKTRONIC (Y page 182) and Blind Spot
Assist (Y page 178) are only available with
limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter accord- ing to the load placed on the vehicle. If nec-
essary, use a trailer with a height-adjusta-
ble drawbar.
Driving tips X
On long and steep downhill gradients,
select shift range 1,2or 3(Y page 145) in
good time.
i This also applies if you have activated
cruise control or SPEEDTRONIC.
X If necessary, shift the transfer case to LOW
RANGE (Ypage 186).
This will use the braking effect of the
engine, so that less braking will be required
to maintain the speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking,
depress the brake pedal repeatedly rather
than continuously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check 192
