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.

XRemove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.

When towingatrailer, your vehicle's handling
characteristic swill be differentinc omparison
with when driving without atrailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris affected more by stron gcrosswinds
Rdemands more sensitive steering
Rhas alarger turning radius
This could impair the handling characteristics.
Adapt your driving style accordingly. Maintain a
safe distance. Drive carefully.
When towing atrailer, alwaysa djust your speed
to the currentr oad and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination.
Notes on towing atrailer
General notes
RDo not exceed the maximum permissible
speed for vehicle/trailer combinations in the
relevant country.
This lowers the risk of an accident.
ROnly install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center.
RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not install hired trailer couplings or other
detachable trailer couplings on the bumpers
of your vehicle.
RIf you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This will reduce the risk of damage to
the ball coupling.
When towing atrailer, set the tire pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tire pres-
sure table in the fuel filler flap (
Ypage 119).
Please not ethat when towing atrailer,
PARKTRONIC (
Ypage 140) and Blind Spot
Assist (Ypage 137) availability is limited or not
available at all. The height of the ball coupling changes with the
load of the vehicle. If necessary, use
atrailer
with aheight-adjustable drawbar.
You will find permissible trailer loads under
"Technical data" (
Ypage 284).
Driving tips
XObserve the notes on ESP®trailer stabiliza-
tion (Ypage 60).
XOn long and steep downhill gradients ,select
shift range 1,2or 3(Ypage 114) in good time.
This also applies if you have activated cruise
control or the speed limiter.
XIf necessary, shift the transfer case to LOW
RANGE (Ypage 146).
This will use the braking effect of the engine, so that less braking will be required to main-
tain the speed. This relieves the load on the
brake system and preventst he brakes from
overheatin gand wearing too quickly. If you
need additional braking, depress the brake
pedal repeatedly rather than continuously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Beforeb eginningthe journey, check the
trailer's document stosee what the maximum
permitted speed is. Observe the maximum per-
missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing atrailer. See the "Technical data"
section to find out whether this applies to your
vehicle (
Ypage 284). In the event of increased
rear axle load, the car/trailer combination may
not exceed amaximum speed of 60 mph
(100 km/ h)for reasons concerning the operat-
ing permit. This als oapplie sinc ountries in
which the maximu mpermissible speedf or car/
trailer combinations is greater than 60 mph
(100 km/h).
When towing atrailer, you rvehicle's handling
characteristics wil lbedifferent in comparison to
when driving without atrailer and it wil lcon-
sume more fuel.

Driving an dpark ing

In order to accumulate driving experience and
accustom yourself to the new handling charac-
teristics, practice the following atalocation
where there is no traffic:
RCornering
RStopping
RBacking up
Before driving, check the following:
RTrailer tow hitch
RSafety switch for braked trailers
RSafety chains
RElectrical connections
RLighting system
RWheelsa nd tires
RLoad-securing measures
Adjust the exterior mirrors to provide an unob-
structed view of the rear section of the trailer.
Trailers with electronically controlled
brakes: pullawaycarefully in the vehicle/trailer
combination, brake manually using the brake
controller and check whether the brakes func-
tion correctly.
Check the load securing measures on aregular
basis.
When towing atrailer, you rvehicle's handling
characteristics willbed ifferent in comparison
with when driving withoutat railer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas alargert urning radius
Avoid sudden steering movements.
Avoid braking abruptly. If possible, brake gently
at first to allow the trailer to run on. Then,
increase the braking force rapidly.
When overtaking, pay particular attention to the
extended length of you rvehicle/trailer combi-
nation.
Due to the length of the vehicle/trailer combi-
nation, you require additional road space when
overtaking before you can change back to the
originall ane.
If the automatic transmission repeatedly shifts
betweeng ears on uphill or downhill gradients,
shift to alowerg ear. Driving in
alowerg ear and at areduced speed
decreases the risk of engine damage.
Avoid constant braking. Otherwise,t he vehicle
brakes and possibly also the trailerb rakes may
overheat.
When driving downhill, shift to alowerg ear to
utilize the engine's braking effect.
If the coolant temperature increases dramati-
cally whilet he air-conditioning system is
switched on, switch off the air-conditioning sys- tem.
Coolant heat can also be dissipated by opening
the windowsa
nd sw
itching the ventilation
blower and the interior temperature to the high-
est level.
Decoupling atrailer
GWARNING
If you uncoupl eatrailerwith the overrun
brake engaged,y ou could trap you rhand
betweent he vehicle and the trailerd rawbar.
There is arisk of injury.
Do not uncoupl eatrailerift he overrun brake
is engaged.
!Do not disconnect atraile rwith an engaged
overrun brake. Otherwise,y ourv ehicle could
be damaged by the rebounding of the overrun
brake.
XApply the parking brake.
XMake sure that the automatic transmission is
set to position P.
XSecure the vehicle and trailera gainst rolling

XClose all doors, including the rear door.
XRemove the trailerc able.
XRemove the safety chains, if there are any.
XUncouple the trailer.
