low oil pressure MERCEDES-BENZ G-Class 2016 W463 Owner's Manual

The following driving systems are specially
adapted to off-road driving:
R4ETS (Ypage 57)
RTransfer case (Ypage 162)
RDifferential locks (Ypage 162)
Observe the following notes:
Rstop your vehicle and, if necessary, shift the
transfer case to LOW RANGE(Ypage 162)
before driving off-road.
Rin transfer case position LOW RANGEthe
ECO start/stop function is not available
(
Ypage 114).
Rengage the differential locks, if necessary
(Ypage 165).
iABS, 4ETS, ESP®and BAS are deactivated
while the differential locks are engaged. This
allows the front wheels to lock briefly, so that
these can dig into a loose surface. However,
please note that locked wheels skid and can
no longer steer.
RCheck that items of luggage and loads are
stowed safely and are well secured
(
Ypage 219).
RTo avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
RAlways keep the engine running and in gear
when driving on a downhill gradient.
RAlways keep the engine running and in gear
when driving on a slope.
RDrive slowly and evenly, if necessary at a
walking pace.
REnsure that the wheels are in contact with the
ground at all times.
RDrive with extreme care on unfamiliar off-road routes where visibility is poor. For safety rea-
sons, get out of the vehicle first and survey
the off-road route.
RCheck the depth of water before fording rivers
and streams.
RWhen fording, do not stop and do not switch
off the engine.
RLook out for obstacles, such as rocks, holes,
tree stumps and furrows.
RAlways keep the doors, rear door, side win-
dows and the sliding sunroof closed while the
vehicle is in motion.
RSwitch off cruise control.
RDo not stray from marked routes or paths.
RAdapt your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower
your speed should be.
RDrive slowly and at an even speed through the
water. Ensure that a bow wave does not form
as you drive.
ROn sand, drive quickly to overcome the rolling resistance. Otherwise the vehicle's wheels
could become st
uck in loose ground.
RDo not jump with the vehicle as this will inter-
rupt the vehicle's propulsion.
RAvoid high engine speeds. Drive at appropri-
ate engine speeds (maximum 3,000 rpm).
RDo not shift the automatic transmission to
transmission position N.
RAlways check the vehicle for damage after off-
road driving.
iInformation about retrofitting special all-ter-
rain tires is available from any qualified spe-
cialist workshop.
iDo not use the HOLD function when driving
off-road, on steep uphill or downhill gradients
or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur-
faces.
Checklist before driving off-road

ted. Check the tire pressure and reactivate the
tire pressure monitor (Ypage 268)if necessary.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount the spare wheel against the
direction of rotation. Adhere to the time restric-
tion on use as well as the speed limitation speci-
fied on the spare wheel.
Storing wheels
Store tires that are not being used in a cool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
GWARNING
When you remove the spare wheel from the
spare wheel bracket, the vehicle’s weight dis-
tribution changes. If the vehicle is already
raised, the jack could tip over. There is a risk
of injury.
Remove the spare wheel from the spare wheel
bracket before lifting the vehicle.
XPrepare the vehicle as described
(Ypage 250).
XRemove the vehicle tool kit and the jack
(Ypage 248).
XSecure the vehicle to prevent it from rolling
away.
XRemove the spare wheel from the spare wheel
bracket (Ypage 249).
iVehicles without a spare wheel or emer-
gency spare wheel are not equipped with a
tire-change tool kit at the factory. For more
information on which tools are required to
perform a wheel change on your vehicle e.g. lug wrench or jack, consult an authorized
Mercedes-Benz Center.
Securing the vehicle to prevent it from
rolling away
XOn level ground:
place chocks or other suit-
able items under the front and rear of the
wheel that is diagonally opposite the wheel
you wish to change.
XOn downhill gradients: place chocks or
other suitable items in front of the wheels of
the front and rear axle.
Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
!The jack is designed exclusively for jacking
up the vehicle at the jacking points. Other-
wise, your vehicle could be damaged.
Observe the following when raising the vehicle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not suited for performing main-
tenance work under the vehicle.
RAvoid changing the wheel on uphill and down- hill slopes.
RBefore raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
