Driving tips
On long and steep downhill gradients,

select shift range 1, 2 or 3 (
good time.

This also applies if you have activated
cruise control or SPEEDTRONIC.
If necessary, shift the transfer case to LOW

RANGE( page 194).

This will use the braking effect of the
engine, so that less braking will be required
to maintain the speed. This relieves the
load on the brake system and prevents the
brakes from overheating and 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. Before beginning the journey, check
the trailer's documents to see what the
maximum permissible speed is. Observe the
legally prescribed maximum speed in the
relevant country.
For certain Mercedes-Benz vehicles, the
maximum permissible rear axle load is
increased when towing a trailer. Refer to the
"Technical data" section to find out whether
this applies to your vehicle. If you utilize any
of the added maximum rear axle load when
towing a trailer, the vehicle/trailer
combination may not exceed a maximum
speed of 60 mph (100 km/h) for reasons
concerning the operating permit. This also
applies in countries in which the permissible
maximum speed for vehicle/trailer
combinations is above 60 mph (100 km/h).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
to when driving without a trailer and it will
consume more fuel.
On long and steep downhill gradients, you
must select shift range 1, 2 or 3 in good time.

Driving tips
If the trailer swings from side to side:
Do not accelerate.
X
Do not counter-steer.
X
Brake if necessary.
X
Maintain a greater distance from the
R
vehicle in front than when driving without a
trailer.
Avoid braking abruptly. If possible, brake
R
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
The values given for gradient-climbing
R
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with
increasing altitude.
Trailer power supply
! You can connect accessories with a
maximum power consumption of 180 W to
the permanent power supply.
You must not charge a trailer battery using
the power supply.
The trailer socket of your vehicle is equipped
at the factory with a permanent power supply.
The permanent power supply is supplied via
trailer socket pin 9.
A qualified specialist workshop can provide
more information about installing the trailer
electrics.
