transmission MERCEDES-BENZ G-Class 2015 W463 Service Manual

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.

(Y page 158). Driving syste

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 replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park-
ing space. Ensure that the areas in front,
behind and to the side of the vehicle are safe
before maneuvering, parking or pulling away. There must not be any persons, animals or
objects in the area in which you are maneu-
vering.
PARKTRONIC does not take into account any persons or objects located below or above
the detection range. As a result,
PARKTRONIC cannot warn you about objects
in this area.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds. PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors General notes
:
Example: sensors in the front bumper,
right-hand side Side view
Top view
The sensors must be free from dirt, ice or
slush. Otherwise, they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(Y page 284). 182

General notes G
WARNING
When the differential locks are engaged, ABS, 4ETS, ESP ®
and BAS are deactivated. As a
result, the wheels could lock when braking
and the braking distance is increased. There is
a risk of an accident.
Disengage the differential locks immediately
on firm surfaces with good grip.
! In order to avoid damage to the transfer
case, you must operate the vehicle on a
dynamometer (1-axle dynamometer) only
if:
R the axle not driven on is jacked up
or
R the corresponding propeller shaft is dis-
connected and the transfer case differ-
ential lock is engaged.
Otherwise, the transfer case can be dam-
aged.
Differential locks improve the traction of the
vehicle. 188
