General
Payload depends on the car's kerb weight. The
total of the weight of the passengers and all
accessories, e.g. towbar, reduces the car's
payload by a corresponding weight. For more
detailed information on weights, see
page 361.
If the towing bracket is mounted by Volvo, then
the car is delivered with the necessary equip-
ment for driving with a trailer.
•
The car's towing bracket must be of an
approved type.
•
If the towbar is retrofitted, check with your
Volvo dealer that the car is fully equipped
for driving with a trailer.
•
Distribute the load on the trailer so that the
weight on the towing bracket complies
with the specified maximum towball load.
•
Increase the tyre pressure to the recom-
mended pressure for a full load. For tyre
pressure label location, see page 309.
•
The engine is loaded more heavily than
usual when driving with a trailer.
•
Do not tow a heavy trailer when the car is
brand new. Wait until it has been driven at
least 1000 km.
•
The brakes are loaded much more than
usual on long and steep downhill slopes.
Downshift to a lower gear and adjust your
speed.
•
For safety reasons, the maximum permit-
ted speed for the car when coupled with a
trailer should not be exceeded. Follow the
regulations in force for the permitted
speeds and weights.
•
Maintain a low speed when driving with a
trailer up long, steep ascents.
•
Avoid driving with a trailer on inclines of
more than 12%.
Trailer cable
An adapter is required if the car's towing
bracket has 13 pin electrics and the trailer has
7 pin electrics. Use an adapter cable approved
by Volvo. Make sure the cable does not drag
on the ground.
Direction indicators and brake lights on
the trailer
If any of the trailer's lamps for direction indica-
tors are broken, then the combined instrument
panel's symbol for direction indicators flashes
faster than normal and the display shows the
text
Bulb fail - Ind. signal trailer .
If any of the trailer's lamps for the brake light
are broken then the
Bulb fail - Stop lamp
trailer text is shown.
Level control*
The rear shock absorbers maintain a constant
height irrespective of the car's load (up to the
maximum permissible weight). When the car is
stationary the rear of the car lowers slightly,
which is normal.
Trailer weights
For information on Volvo's permitted trailer
weights, see page 361.
NOTE
The stated maximum permitted trailer
weights are those permitted by Volvo.
National vehicle regulations can further limit
trailer weights and speeds. Towbars can be
certified for higher towing weights than the
car can actually tow.
WARNING
Follow the stated recommendations for
trailer weights. Otherwise, the car and trailer
may be difficult to control in the event of
sudden movement and braking.
Manual gearbox
Overheating
When driving with a trailer in hilly terrain in a hot
climate there may be a risk of overheating.
•
Do not run the engine at higher revolutions
than 4500 rpm (diesel engines: 3500 rpm)
- otherwise the oil temperature may
become too high.
