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
!If the engine oil warning lamp lights up while
the vehicle is in motion, stop the vehicle in a
safe place as soon as possible. Check the
engine oil level. The engine oil warning lamp
warning must not be ignored. Continuing the
journey while the symbol is displayed could
lead to engine damage.
XOil level: check the engine oil level and add oil
if necessary.
Only then does the engine receive enough oil when the vehicle is on a steep incline.
XTire-changing tool kit: check that the jack is
working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
XWheels and tires: check the tire tread depth
and tire pressure.
XCheck for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tires.
XReplace any missing valve caps.

for possible damage, especially to the under-
body and the components of the chassis.
!Drive with particular care when driving over
an obstacle while driving up or down a steep
slope.
The vehicle could otherwise tilt and slide side-
ways or tip over.
Observe the following rules when driving over
tree stumps, large stones and other obstacles:
RObserve the safety notes (Ypage 137) and
the general notes (Ypage 137) on off-road
driving.
RShift the transfer case to LOW RANGE
(Ypage 162).
RAvoid high engine speeds.
RRestrict the shift range to 1(Ypage 123).
RMake sure that you have enough ground
clearance before driving across an obstacle.
RDrive very slowly.
RTry to drive straight over the center of obsta-
cles: front wheel first, then rear wheel.
Traveling uphill
Approach/departure angle
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
Always observe the approach/departure angle
values (
Ypage 296).
RObserve the safety notes (Ypage 137) and
the general notes (Ypage 137) on off-road
driving.
RDo not drive at an angle on slopes, inclines or
gradients, but instead follow the direct line of
fall. Note that the climbing ability of your vehi- cle depends on the terrain conditions.
RBefore driving on extreme uphill and downhillgradients, shift the transfer case to LOW
RANGE (
Ypage 162).
REngage the differential locks, if necessary
(Ypage 165).
RDrive slowly.
RAccelerate gently and make sure that the
wheels are gripping.
RAvoid high engine speeds, except when driv-
ing on sandy and muddy routes with high driv-
ing resistance.
RAvoid high engine speeds – drive at an appro-
priate engine speed (maximum 3,000 rpm).
RWhen driving down an incline, make use of the
engine's braking effect. Observe the engine
speed; do not overrev the engine.
iFurther information on the maximum engine
speed: (Ypage 171).
RSelect a shift range appropriate to the gradi-
ent.
RBefore tackling steep downhill gradients,
select shift range 1(Ypage 123).
RAlways check the brakes after driving off-
road.
iHill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
(
Ypage 114).
Maximum gradient-climbing capability
Always observe the maximum gradient climbing ability values (Ypage 297).
Hilltops
When driving on an uphill gradient, reduce pres-
sure slightly on the accelerator immediately
before reaching the top of the hill (do not shift
the transmission to position N). Use the vehi-
cle's own impetus to drive over the top of the
hill.
This style of driving prevents:
Rthe vehicle from lifting off the ground on the
brow of a hill
Rloss of traction
Rthe vehicle from traveling too quickly down
the other side
Driving downhill
RBefore tackling steep downhill gradients,
select shift range 1(Ypage 123).
This way you use the engine's braking effect
to reduce the speed. If this is not sufficient,
brake gently. When doing so, make sure that
