Heavy and light loads
GWARNING
If you rest you rfoot on the brake pedalw hile
driving, the braking system can overheat. This increases the stopping distance and can even
caus ethe braking system to fail .There is a
risk of an accident.
Never use the brake pedalasaf ootrest. Never
depress the brake pedala nd the accelerator
pedalatt he same time.
!Depressing the brake pedalc onstantly
results in excessive and premature weart o
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehiclei mmediately. Drive
on for ashort while. This allows the airflow to
cool the brakes more quickly.
Wet roads
If driving in heavy rain for aprolonged period of
time without braking, there may be adelayed
reactio nfrom the brakes when braking for the
first time. This may als ooccur after the vehicle
has been washed.
You have to depress the brake pedalm ore
firmly.M aintainagreater distance from the
vehicleinf ront.
After driving on awet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This wil lwarmupt he
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, alayer of sal tresi-
due may form on the brake discs and brake
pads. This can result in asignificantly longer
braking distance.
RIn order to prevent any sal tbuild-up, apply the
brakes occasionall ywhile paying attention to
the traffic conditions.
RCarefully depress the brake pedala nd the
beginning and end of ajourney.
RMaintain agreater distance to the vehicle
ahead.

124Driving tips
Driving and parking

Familiarize yourself with the characteristics of
your vehicle and the gearshift operation before
driving through difficult terrain.
The following driving systems are specially
adapted to off-roadd riving:
R4ETS (Ypage 59)
ROff-roadABS (Ypage 58)
RTransfer case (Ypage 145)
RDifferentia llocks (Ypage 120)
Observe the following notes:
RStop the vehicle before yo udrive off-roada nd,
if necessary ,shift the transfe rcase to the off-
roadd riving position LOW RANGE
(
Ypage 146).
REngag ethe differential locks if necessary
(Ypage 148).
iABS, 4ETS, ESP®and BAS are deactivated
while the differential locks are engaged.T his
allow sthe front wheels to lock briefly, so that
these can dig into aloose surface .However,
please note that locke dwheels skid and can
no longer steer.
RCheck that items of luggage and loads are
stowed safely and are well secured
(
Ypage 209).
RTo avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
RAlway skeep the engine running and in gear
whe ndriving on adownhil lgradient.
RAlway skeep the engine running and in gear
whe ndriving downani ncline.
RDrive slowlyand evenly, if necessary at a
walking pace.
REnsure that the wheels are in contact with the
ground at al ltimes.
RDrive with extreme care on unfamilia roff-road
routes where visibility is poor. For safety rea-
sons, get ou

tofthe vehicle firs tand survey
the off-roadr oute.
RCheck the depth of water before fording rivers
and streams.
RWatch outfor obstacles.
RAlwayskeep the doors, reard oor, sidewin-
dowsa nd the sliding sunroof closed while the
vehicle is in motion.
RSwitch off cruise control.
RDo not deviate from marke droutes.
RAdap tyou rspeed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower
your speed should be.
RDo not jump with the vehicle. as this will inter-
rup tthe vehicle' spropulsion.
RAvoid hig hengine speeds .Drive at appropri-
ate engine speeds (maximu m3,000 rpm).
RDo not shift the automatic transmission to
position N.
RAlwayscheck the vehicle for damag eafteroff-
roadd riving.
Do not use the HOLD function whe ndriving off-
