2014 MERCEDES-BENZ G-Class tire pressure

R
you depress the brake pedal again with a
certain amount of pressure until 00D9
disappears 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.4MATIC (permanent four-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
position 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
dynamometer. 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.
4MATIC ensures that all four wheels are
permanently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever 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 Accelerate less when driving.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane. Only engage
4MATIC when the current road, weather and
traffic conditions permit it to be done safely,
and adapt your driving style accordingly.
Drive carefully and maintain a suitable
distance to the vehicle in front.
i
In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
For information about driving off-road, see
(Y page 164). PARKTRONIC
Important safety notes !
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Ensure that the
areas in front, behind and to the side of the Driving systems
189Driving and parking Z

Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
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
gradient-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 circle
This could impair the handling
characteristics.
When towing a trailer, always adjust your
speed to the current road and weather
conditions. Do not exceed the maximum
permissible speed for your vehicle/trailer
combination.
General notes R
Do not exceed the legally prescribed
maximum speed for vehicle/trailer
combinations 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
suitable for installing detachable trailer
couplings.
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
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y page 316).
You will find installation dimensions and loads
in the technical data (Y page 351).
The maximum noseweight of the trailer
drawbar on the ball coupling for up to 3
people is 562 lbs (255 kg). The maximum
permissible trailer drawbar noseweight for
more than 3 persons and the maximum load
in the trunk can be found in the trailer
drawbar noseweight table (Y page 352).
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
or trailer identification plates. The lowest
weight applies.
i When towing a trailer, set the tire
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y page 316).
Please note that when towing a trailer,
PARKTRONIC ( Ypage 189) and Blind Spot
Assist (Y page 185) are only available with
limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter
according to the load placed on the vehicle.
If necessary, use a trailer with a height-
adjustable drawbar. Towing a trailer
