Important safety notes
G
WARNING
Only remove the key from the ignition lock
when the vehicle is stationary, as you can not
steer the vehicle when the key is removed.
Never leav echildren unsupervised in the vehi-
cle. They might release the electric parking
brake. This coul dlead to aserious or fatal
accident. G
WAR
NING
Under no circumstances should the exhaust
system come into contact with flammable
materials such as dry grass or petrol ,for
example. Do not par kthe vehicle on dry grass-
lan dorh arvested grain fields. The hot exhaust
system could otherwise ignite the flammable
material and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on steep uphill or downhill gradients, turn
the fron twheels towards the kerb. Switching of
fthe engine
Important safety notes G
WARNING
Neve rswitch off the engine while the vehicle
is in motion.
There is no brake boost for the service brake
if the engine is not running. If the ignition is
switched off, there is also no power assis-
tance for the steering.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident.

Off-road driving
Important safet ynotes G
WARNING
Driv eslowly in rough terrain with which you
are unfamiliar. This will allow you to detect
unexpected obstacles more easily and, there-
fore, to reduce the risk of an accident.
Do not make U-turns on mountain roads. Oth-
erwise, the vehicle could tip over. If aslope is
too steep for the vehicle, drive back in reverse
gear.
Do not drive at an angle up steep inclines.
Otherwise, the vehicle could tip over. If you
drive up asteep incline at an angle and the
vehicle threatens to overturn, stee rinto the
line of fall immediately.
Never allo wthe vehicle to roll backwards. The
brakin geffect of the engine canno tbeu tilised
in neutral. If you only use the service brake,
you could los econtrol of the vehicle. G
WARNING
Grains of sand, particles of dirt and other
abrasiv ematerials can enter the brake sys-
tem. This can lead to excessive wear and
unpredictable braking efficiency.
After the brakes have been expose dtodirty
conditions ,have them checked and cleaned
at aq ualified specialist workshop ,e.g. a
Mercedes-Benz Service Cent re.O therwise,
there is arisk that braking power may be
insufficient in the event of an emergency, or
that the braking effec tmay be unpredictable. G
WARNING
Damage to the vehicle creates the risk of an
accident for yourself and other road users. If
in doubt, have your vehicle chec kedataq uali-
fied specialist workshop which has the nec-
essary specialist knowledg eand tool stocarry
out the work required. Mercedes-Benz rec-
ommends that you use aMercedes-Benz
Servic eCentr efor this purpose. General notes Read this section befor
edriving your vehicle
off- road. Practise by travelling over more gen-
tle off-road terrain first.
The following driving systems are specially
adapted to off-road driving:

erwise, the vehicle could slip sideways, tip
and over turn.
R Before tackling steep downhill gradients,
select shift range 1.
R Activat eDSR. If this is not suffici ent, brake
gently. Whe ndoing so, make sure that the
vehicle is facing in the direction of the line
of fall.
R Check that the brakes ar eworking normally

i Off-road ABS is activated when the off-
road program or LOW RANGE off-road gear
is selected.
At speeds belo w30km/h, th efront wheels
lock cyclicall yduring braking. The digging-
in effect achieved in the process reduces
the stopping distance when driving off-

siderably reduced if the wheel slock. Driving systems
Cruise control
Important safety notes G
WARNING
Do not change down for additiona lengine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic conditions that do not allow you to
drive at aconstant speed (e.g. heavy traffic or winding roads). You may otherwise
cause an accident.
R on slipper yroads. The driv ewheels may
lose their grip when brakin goraccelerating
and the vehicle may skid.
R whe nthere is low visibility, e.g. due to fog,
heav yrain or snow.
General notes Cruise control maintains
aconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
select shift range 1,2or 3in good time. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevent sthe brakes
from overheating and wearing too quickly.
Use cruise con trol only if roa dand traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan
store any road spee dabove 30 km/h.

vehicle agility. Depending on the AD Smode 188
Driving systemsDriving and parking

selected (Y
page 188), the Ac tiveCurve Sys-
tem also changes the setting.
If you select ADS comfort mode:
R rolling movement is reduced in the event of
changing surface undulations.
R the roll angle when cornering is reduced.
R the driving style is agile.
If you select ADS sport mode:
R the roll angle is reduced significantly.
R the driving style is even more agile.
Leve lcontrol Import
ants afety notes
Leve lcontrol adapts the vehicle leve lauto-
matically to the current operating and driving
situation. This results in reduced fuel con-
sumption and improved handling.
If you select ADS comfort mode
(Y page 188), the vehicle is lowered to high-
spee dlevel as the speed increases. As the
vehicle decelerates, the vehicle is raised back
up to highway level.
If you select ADS sport mode (Y page 188),
the vehicle skips highway level and lowers
directly to high-speed level dependin gonthe
basic setting (Y page 189).
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as pos-
sible.
The vehicle level ma ychange visibly if you
par kthe vehicle and the outside temperature
changes. If the temperature drops, the vehi-
cle level lowers; with an increase in temper-
ature, the vehicle level rises.
If you unlock the vehicle or open adoor, the
vehicle begins to compensat efor load dis-
crepancies while still parked. However, for
significant leve lchanges, e.g. after the vehi-
cle has been stationary for along period, the
engin emust be on. For safety reasons, the
vehicle is only lowered when the doors are
closed .Lowering is interrupted if adoor is opened; it con
tinues once the doo rhas been
closed. G
WARNING
Make sure that nobody is near the wheel arch
or vehicle underside when you make achange
to the vehicle level. Otherwise, you or others
ma ybet rapped. G
WARNING
Always select as lo wavehicle level as possi-
ble. If the vehicle level is high, the vehicle
centre of gravity shifts upwards. This increa-
ses the risk of the vehicle tipping over.
Adapt your driving style to suit the vehicle
level. ESP ®
cannot reduc ethe risk of an acci-
dent if you drive too fast. ESP ®
cannot over-
rid ethe laws of physics.
! When driving on extremel yrough terrain,
select ahigh vehicle level in good time.
Make sure there is always sufficient ground
clearance to prevent damage to the vehi-
cle.
For information abou tdriving off-roa d, see
( Y page 166).
Basic settings
The exten ttowhich the vehicle is rai sedor
lowered depends on the basic setting selec-
ted. Select raised level for off-road driving or
highway/high-spee dlevel for normal roads.
The indiv idua lvehicle levels differ from high-
way level as follows:
R Highway level: +/ –0mm
R High-speed level: –15 mm
R Raised level: +60 mm
Raise dlevel
Only select raise dlevel if this is appropriate
for the road conditions. Otherwise, fuel con-
sumption may increase and handling may be
affected. Driving systems
