Tips for driving with DISTRONIC PLUS
Pay particular attention in the following traffic
situations:
RCornering, entering and exiting abend: the
ability of DISTRONIC PLUS to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or late.
RDriving on adifferent line: DISTRONIC PLUS
may not detect vehiclesw hich are not driving
in the middleoft heir lane. The distance to the
vehicle in front willbet oo short.
ROther vehicleschanging lane: DISTRONIC
PLUS has not detected the vehicle cutting in
yet. The distance to this vehicle willbet oo
short.
RNarrow vehicles: DISTRONIC PLUS does not
detect the vehicle in front on the edge of the
road because of its narrow width. The dis-
tance to the vehicle in front willbet oo short.
RObstacles and stationary vehicles:
DISTRONIC PLUS does not brake for obsta-

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.
