Driving and parking

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.
Servicing the brakes
!The brake flui dlevelm ay be too low,i f:
Rif the red brake warning lamp lights up in
the instrument cluste rand
Ryou hearaw arning tone while the engine is
running
Observe additiona lwarning messages in the
multifunction display.
The brake flui dlevelm ay be too low due to
brake pad wearorl eaking brake lines.
Have the brake system checked immediately. Consult aqualified specialist workshopt o
arrange this.
!If the brake warning lamp lights up in the
instrument cluste rand you hearaw arning
tone even though the parking brake has been
released ,the brake flui dlevelm ay be too low.
Observe additionalw arning messages in the
multifunction display.
The brake flui dlevelm ay be too low due to
brake pad wearorl eaking brake lines.
Have the brake system checked immediately.
This work should be carrie dout at aqualified
specialist workshop.
!Af unction or performance test should only
be carrie dout on a2-axle dynamometer. If
you wis htooperate the vehicleons uch a
dynamometer, please consul taqualified spe-
cialist workshopina dvance. You couldoth-
erwise damage the drive train or the brake
system.
!The ESP®system operates automatically.I f
the parking brake is tested on abrake dyna-
mometer (for amaximu moften seconds),t he
engine and the ignitio nmust be switched off.
Braking triggereda utomatically by ESP
®may
otherwise caus esevere damage to the brake
system.
All checks and maintenance work on the brake
system must be carrie dout at aqualified spe-
cialist workshop.
Have brake pad sinstalled and brake fluid
replaced at aqualified specialist workshop.
If the brake system has only been subject to
moderate loads, you shoul
d test the functional-
ity of you rbrakes at regular intervals.

124Driving tips
Driving and parking

for possible damage, especially to the under-
body and the components of the chassis.
!Drive with particularcare when driving over
an obstacle while driving up or downas teep
slope.
The vehiclec ouldotherwise tilt and slide side-
ways or tip over.
Observe the following rules when driving over
tree stumps ,larg estones and other obstacles:
RObserve the safety notes (Ypag e127) and
the generaln otes (Ypage127) on off-road
driving.
RShift the transfer case to the off-road driving
position LOW RANGE (Ypage146).
RAvoid high engine speeds.
RShift the automatic transmission to alow
gear.
RMake sure that you have enoug hground
clearance before driving across an obstacle.
RDrive very slowly.
RTry to drive straight over the center of obsta-
cles: front wheelf irst, then rear wheel.
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.
Hill start assist wil laid you when pulling away on
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

Blind Spot Assist
General notes
Blind Spot Assist monitor sthe areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facingr adar sen-
sors. Awarning lamp lights up in the exterior
mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical and
audiblew arning.
Blind Spot Assist supports you from aspeed of
approximately 20 mph (30 km/h).
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with alarge speed
differential and overtak eyour vehicle
As aresult, Blind Spot Assist may not give
warnings in such situations. There is arisk of
an accident.
Always observe the traffic conditions care-
fully, and maintain asafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
