GWARNING
Drinking and driving and/o rtaking drugs and
driving are very dangerous combinations.
Even asmall amount of alcoholord rugs can
affect your reflexes,p erceptions and judg-
ment.
The possibility of aseriousore ven fatalacci-
dent is greatly increased whe nyou drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has bee ndrinking or tak-
ing drugs.
Emissionc ontrol
GWARNING

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.

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.
REstablish how deep the water is and the char-
acteristics of the body of water before ford-
ing.
RSwitc hoff automatic climate control
RShift the transfer case to the off-road driving
position LOW RANGE (Ypage 145).
REngage the differential locks if necessary
(Ypage 148).
RAvoid high engine speeds.
REnter and exit the water at aflat place and at
as teady walking pace.
RDrive slowly and at an even speed through the
water.
REnsure that abow wave does not form as you
drive.
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-
ing.
RApply the brakes to dry them after fording. Always observe the fordingd
epth values
(
Ypage 283).
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

Travelinguphill
Approach/departure angle
GWARNING
If you drive on asteep incline at an angle or
turn when driving on an incline ,the vehicle
coul dslips ideways, tip and rollover. There is a
risk of an accident.
Always drive on asteep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
Always observe the approach/departure angle
values (
Ypag e283).
RObserve the safety notes (Ypag e127) and
generaln otes (Ypage127) on driving off-
road.
RDo not drive at an angle on slopes, incline sor
gradients, but instead follow the direct line of
fall .Note that the climbing ability of you rvehi-
cle depends on the terrai nconditions.
RBefore driving on extreme uphill and extreme
downhill gradients, set the transfer case to
the off-road driving position LOW RANGE
(
Ypag e146).
REngage the differential locks if necessary
(Ypag e148).
RDrive slowly.
RAccelerate gently and make sure that the
wheels are gripping.
RAvoid high engine speeds, except when driv-
ing on sandy and mudd yroutes with high driv-
ing resistance.
RAvoid high engine speeds –drive at an appro-
priate engine speed( maximum 3,000 rpm).
RWhen driving downani ncline,make use of the
engine'sb raking effect. Observe the engine
speed; do not overrev the engine.
Further information on the maximu mengine
speed: (
Ypag e157).
RShift the automatic transmission to alow gear
appropriate for tackling an uphill gradient or a
long, steep downhill gradient.

ah ill. For further information about hills tart
assist, see (
Ypag e127).
Maximum gradient-climbing capability
Always observe the maximu mgradient climbing
ability values (Ypag e283).
Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
before reaching the brow of the hill( do not shift
the transmission into N).Make use of the vehi-
cle's own impetus to travel over the brow.
This style of driving prevents:
Rthe vehiclef rom lifting off the ground on the
brow of ahill
Rloss of traction
Rthe vehiclef rom traveling too quickly down
the other side
Driving downhill
RDrive slowly.
RDo not drive at an angle downs teep inclines.
Steer into the line of fall and drive with the
front wheels aligned straight. Otherwise, the
vehiclec ouldslips ideways, tip and rollover.
RBefore tackling steep downhill gradients, shift
the automatic transmission to alow gear.
By doing so, you wil luse the braking effect of
the engine to reduce the speed. If this is not

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.
