Mercedes-Benz CLK-Class Owner's Manual page 266

You should not exceed a maximum
speed of 80 km/h, even in countries
where higher speeds are permitted.
Avoid sudden braking. Instead, apply
the brake lightly at first, to allow the
trailer to overrun. Then increase the
braking force rapidly.
If the trailer starts to swing, reduce
your speed, do not attempt corrective
steering, and brake if necessary. On no
account should you attempt to draw
the vehicle/trailer combination out by
increasing your speed.
The gradient-climbing capabilities from
a standstill are correct for sea level.
When driving in mountainous areas,
note that the power output of the en-
gine, and with it its gradient-climbing
capability from a standstill, decreases
with increasing altitude.
!
Do not uncouple a trailer with an overrun
brake when the brake is engaged. The spring
action of the overrunning brake mechanism
could damage the bumper.
Removing the ball coupling
Fold out the socket under the vehicle.
Remove the locked protective cap on
the handwheel.
Unlock the lock on the handwheel
using the key.
Hold the ball coupling firmly. Lift the
handwheel off the ball coupling and
turn the handwheel clockwise until it
engages.
The red marking on the handwheel is
aligned with the white marking.
Remove the ball coupling by pulling
downwards.
Press the ball coupling cover into the
ball coupling recess.
Make sure that the cover is fitted se-
curely.
Trailer towing
Stowing the ball coupling
Stow the ball coupling in the ball
coupling well by the spare wheel.
G
Risk of accident
Do not carry the ball coupling unsecured in
the vehicle interior.
Vehicle occupants could be injured by the
ball coupling being thrown around in the
vehicle in the event of:
sharp braking
a change of direction or
an accident
