R
has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R consumes more fue l
On long and steep downhill gradients you
must select a lower gear in good time, or on
vehicles with automatic transmission*, select
the shift range 1,2 or 3.
i This also applies if you have activated
cruise control* or Speedtronic*.
This uses the braking effect of the engine and
you will not have to brake to such an exten t
to maintain the same 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. G
Risk of accident
Never depress the brake pedal continu -
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. Driving tips
R
Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine
and with it its gradient-climbing capability
decrease with increasing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. G
Risk of accident
On no account should you attempt to dra w
the vehicle/trailer combination out by
increasing speed. Folding in the ball couplin

i Fold in the ball coupling when you are not
using the trailer tow hitch . G
Risk of injury
Make sure that no persons or animals are
in the pivoting range of the ball coupling.
Otherwise, they could be injured .
The release wheel is located behind the side
trim panel in the boot/luggage compartment. Saloon

Risk of injury
The jack is designed only to raise and hol d
the vehicle for a short time while a whee l
is being changed.
If you are carrying out work on the vehicle,
you must use stands.
Make sure that the jack is placed on a firm ,
non-slip and level surface. Do not us e wooden blocks or similar objects as a jac
k
underlay. Otherwise the jack will not be
able to achieve its load-bearing capacit y
due to the restricted height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is bein g
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid is opened or closed) and you
could be seriously injured.
