STARTING AND DRIVING
}}
403
•
It is necessary to balance trailer brakes with
the towing vehicle brakes to provide a safe
stop (check and observe state/local regula-
tions).
•
Do not connect the trailer's brake system
directly to the vehicle's brake system.
•
More frequent vehicle maintenance is
required.
•
Remove the ball holder when the hitch is not
being used.
NOTE
•
When parking the vehicle with a trailer on
a hill, apply the parking brake before put-
ting the gear selector in
P
. Always follow
the trailer manufacturer's recommenda-
tions for wheel chocking.
•
When starting on a hill, put the gear
selector in
D
before releasing the parking
brake.
•
If you use the manual (Geartronic) shift
positions while towing a trailer, make sure
the gear you select does not put too
much strain on the engine (using too
high a gear).
•
The drawbar assembly/trailer hitch may
be rated for trailers heavier than the vehi-
cle is designed to tow. Please adhere to
Volvo's recommended trailer weights.
•
Avoid driving with a trailer on inclines of
more than 15%.
CAUTION
The maximum trailer weights listed are only
applicable for altitudes up to 3,280 ft
(1000 m) above sea level. With increasing
altitude the engine power and therefore the
car's climbing ability are impaired because of
the reduced air density, so the maximum
trailer weight has to be reduced accordingly.
The weight of the vehicle and trailer must be
reduced by 10% for every further 3,280 ft
(1,000 m) (or part thereof). When towing
5,000 lbs (2,250 kg) hill inclination is restric-
ted to 14%.
