erwise, water may enter the vehicle interior or
the engine compartment.This can damage
the electronic component sinthe engine or
the automatic transmission. Water can also
be drawn in by the engine' sair suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rin the case of standin gwater, the water level
must be no higher than the lower edge of the
vehicle body
Ryou should drive no faster than walking pace
Off-road fording
!Under no circumstances should you accel-
erate before entering the water. The bow
wave could cause water to enter and damage
the engine and other assemblies.
!Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment.
iYou may only drive through fresh water.
RObserve the safety notes (Ypage 127) and
general notes (Ypage 127) on driving off-
road.

acteristics of the body of water before ford-
ing.

REnsure that abow wave does not form as you

RDo not stop and do not switch off the engine.
Water offers ahigh degree of resistance, and
the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in water.
RClean any mud from the tire tread after ford-

Winter driving
GWARNING
If you shift down on aslippery road surface in
an attempt to increase the engine' sbraking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on aslippery road surface.
GWARNING
If you select the LOW RANGE off-road gear on
as lippery road surface, the wheels could lose
traction:
Rif you remove your foot from the accelera-
tor pedal when driving
Rif off road ABS intervenes when braking
If the wheels lose traction .the vehicle can no
longer be steered. There is an increased dan-
ger of skidding and accidents.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces.
Have your vehicle winter-proofed at aqualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steerin gand
braking maneuvers. Do not use cruise control or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the automatic transmission to position
N .
The outside temperature indicator is not
designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after ashort delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. The vehicle could
skid if you fail to adapt your driving style. Always

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

RDrive slowlyand evenly, if necessary at a

ground at al ltimes.
RDrive with extreme care on unfamilia roff-road
routes where visibility is poor. For safety rea-
sons, get ou

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

RAlwayscheck the vehicle for damag eafteroff-
roadd riving.
Do not use the HOLD function whe ndriving off-

slippery or loose surfaces. The HOLD function
cannot holdt he vehicle on such surfaces.

Checklist before driving off-road
!If the engine oil warning lamp lights up while
the vehicle is in motion, stop the vehicle in a
saf ep lace as soona spossible. Check the
engine oil level. The engine oil warning lamp
warning mus tnot be ignored.C ontinuing the
journey while the symbol is displaye dcould
lea dtoe ngine damage.
XEngin eoillevel: check the engine oil level
and ad doil if necessary.
Whend riving on steep gradients, the engine
oil level mus tbes ufficiently hig htoensure a
correct oil supply in the vehicle.
XTire-changing too lkit: check that the jack is
working and make sur eyou hav ethe lug
wrench, arobust tow cable and afolding
spade in the vehicle.
XWheels and tires: check the tire treadd epth
and tire pressure.
XCheck for damag eand remove any foreign
objects, e.g. small stones,f rom the wheels/
tires.
XReplace any missing valve caps.
XReplace dente dordamaged wheels .Also
check the spare wheel.
XRims: dentedorbent rims can result in aloss
of tire pressure and damag ethe tire bead.
Befored riving off-road, check the wheels and
replace them if necessary.

sufficient, brake gently. When doing so, make
sure that the vehicle is facing in the direction
of the line of fall.
RObserve the notes on driving in mountainous
terrain (Ypage 130).
RCheck that the service brake is working nor-
mally after along downhill stretch.
When driving at speeds below 37 mph
(60 km/h), off-road ABS is activated and the
front wheels lock cyclically during braking. The
digging-in effect achieved in the process
reduces the stopping distance on off-road ter-
rain. This limits steering capability.
Driving systems
Cruise control
General notes
Cruise control maintains aconstant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Change into alower
gear in good time on long and steep downhill
gradients.
This is especiallyi mportant if the vehicle is
laden. By doing so, you will make use of the
braking effect of the engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain asteady
speed for aprolonged period. You can store any
road speed above 20 mph (30 km/h).
Do not activate cruise control on off-road jour-
neys.
Important safety notes
Cruise control can neither reduce the risk of an
accident if you fail to adapty our driving style nor
override the laws of physics. Cruise control can-
not take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for maintaining asafe
distance to the vehicle in front,f or vehicle
speed, for braking in good time and for staying in
lane.
Do not use cruise control:
Rin road and traffic conditions that do not allow
you to maintain aconstant speed, e.g. in heavy traffic, on winding roads or on rough
terrain
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
If there is achange of drivers, advise the new
driver of the speed stored.
iThe speed indicated in the speedometer
may differ slightly from the speed stored.
