Mercedes-Benz G-Class 2011 Owners Manual - Manual (Page 151)

4MATIC (permanent all-wheel drive)
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.
G Warning!
If a drive wheel is spinning due to insufficient
traction:
R While driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4MATIC cannot prevent accidents
resulting from excessive speed.
! 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.
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.
! 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 key to position
0 or 1 in the ignition. Failure to do this can
cause damage to the drive train or the
brake system.
! Function or performance tests may only
be performed on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult an
authorized Mercedes-Benz Center
beforehand. You could otherwise damage
the drive train or the brake system.
For information about driving off-road, see

Y page 142).

Important safety notes
G Warning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
G Warning
Rear Parking Assist is a supplemental system.
It is not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always remains with the driver.
The ultrasonic backing up aid is an electronic
parking aid. It indicates visually and audibly
the distance between the rear area of your
vehicle and an object.
The ultrasonic backing up aid is activated
automatically when you switch on the ignition
and engage reverse gear.
The ultrasonic backing up aid monitors the
rear area of your vehicle using four sensors in
the rear bumper.
