Towing a trailer
There are many different laws, including
speed limit restrictions, having to do with
trailer towing. Make sure your rig will be legal,
not only for where you reside, but also for
where you will be driving. A good source for
this information can be the police or local
authorities.
Note the following, when driving with a trailer:
R In order to gain skill and an understanding
of the vehicle’s behavior, you should
practice turning, stopping and backing up
in an area which is free of traffic.
R Before you start driving check the
- trailer hitch
- break-away switch
- safety chains
- electrical connections
- lighting
- tires
R Adjust the mirrors ( Y page 84) to permit
unobstructed view beyond rear of trailer.
R If the trailer has electric brakes, start your
vehicle and trailer moving slowly, and then
apply only the trailer brake controller by
hand to make sure the brakes are working
properly.
R Always secure items in the trailer to
prevent load shifts while driving.
R When towing a trailer, check occasionally
to make sure the load is secure, and that
trailer lighting and brakes (if so equipped)
are functioning properly.
R Take into consideration that when towing a
trailer, the handling characteristics are
different and less stable from those when
operating the vehicle without a trailer.
It is important to avoid sudden maneuvers.
R The vehicle and trailer combination is
heavier, and therefore limited in
acceleration and climbing ability, and has a
larger braking distance.
It is more prone to reacting to cross wind
gusts, and requires more sensitive steering
input.
R If possible, do not brake abruptly, but
rather engage the brake slightly at first to
permit the trailer to activate its brake. Then
increase the braking force.
! If the trailer should begin to sway, reduce
the vehicle’s speed immediately.
Do not attempt to straighten out the tow
vehicle and trailer by increasing the speed.
R If the transmission shifts between gears on
inclines repeatedly, shift to a lower gear
range manually ( Y page 106). Select 4, 3 ,
2 or 1.
A lower gear and reduction of speed
reduces the chance of engine overloading
and/or overheating.
R When going down an incline, shift into a
lower gear and use the engine’s braking
effect.
Avoid riding the brakes, thus overheating
the vehicle and trailer brakes (if so
equipped).
R If the engine coolant rises to an extremely
high temperature when the air conditioning
is on, turn off the air conditioning system.
Engine coolant heat can be additionally
vented by opening the windows, switching
the climate control fan speed to high and
setting the temperature control to the
maximum.
R During a passing maneuver extreme care
must be exercised since your vehicle with
a trailer will require additional passing248Driving instructionsOperation

Mercedes-Benz approved Paint Care should
be applied when water drops on the paint
surface do not “bead up”. This should
normally be done every 3 to 5 months,
depending on the climate and washing
detergent used.
Mercedes-Benz approved Paint Cleaner
should be applied if the paint surface shows
signs of embedded dirt (i.e. loss of gloss).
Do not apply any of these products or wax if
your vehicle is parked in the sun or if the hood
is still hot.XUse the appropriate MB-Touch-Up Stick for
quick and provisional repairs of minor paint
damage (i.e. chips from stones, vehicle
doors, etc.).
Engine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical components
and connectors from contact with water and
cleaning agents.
Corrosion protection, such as MB
Anticorrosion Wax should be applied to the
engine compartment after every engine
cleaning. Before applying, all control linkage
bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be
protected from any wax.
Vehicle washing
In the winter, thoroughly remove all traces of
road salt as soon as possible.
When washing the vehicle underbody, do not
forget to clean the inner sides of the wheels.
Hand-wash
XDo not use hot water or wash your vehicle
in direct sunlight.XOnly use a soft, wet cloth or sponge to
clean the vehicle.XOnly use a mild vehicle wash detergent,
such as Mercedes-Benz approved Car
Shampoo.XThoroughly spray the vehicle with a
diffused jet of water.XDo not spray directly towards the
ventilation intake.XUse plenty of water and rinse the sponge
and chamois frequently.XRinse with clean water and dry with a
chamois thoroughly.
Do not allow cleaning agents to dry on the
finish.
Automatic car wash
You can have your vehicle washed in an
automatic car wash from the start. Brushless
car washes are preferable.
XTo protect the filter system, activate the air
recirculation mode using button g on
the climate control panel.
! Do not clean your vehicle in an automatic
touchless car wash which uses caustic
spray. Caustic spray will damage the paint
or ornamental moldings.
If the vehicle is very dirty, prewash it before
running it through the automatic car wash.
! Make sure the combination switch is set
to wiper setting $. Otherwise, the rain
sensor could activate and cause the wipers
to move unintentionally. This may lead to
vehicle damage.
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running
the vehicle through an automatic car wash
to prevent damage to the mirrors.
XWhen taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N.
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
