Trailer towing
Driving with a trailer
General information
Your vehicle is primarily intended for transport­ ing people and luggage . However, if you drive
with a trailer , follow the technical requirements,
the operation and driving tips, and the legal reg­
ulations.
Driving with a trailer affects the vehicle's fuel
consumption, performance and wear.
It also re­
quires higher concentration from the driver.
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removable ball hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle , the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol­
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys­
tem must be designed for additional load and
contain enough coolant
c::> (D .
A WARNING
-
-Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trail­
er hitch . The vehicle was not designed for
these types of trailer hitches . The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
- If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in­
creases the risk of an accident.
- To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount­
ed.
(D Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out­
side temperatures are high. otherwise, this
increases the risk of engine damage.
' Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
The permitted towing capacity for trailers with­
out brakes is 1,650 lbs (750 kg).
The permitted towing capacity for trailers with brakes is 2,200 lbs (1,000 kg) .
These values apply to roads with up to 12% in­
cline.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded. ..,.
