NOTE
Some models require an oil cooler for the
automatic gearbox when driving with a trail-
er. Check with your nearest Volvo dealer as
to what applies to your car if you have a ret-
rofitted towbar.

Steep inclines
• Select an appropriate manual gear posi-
tion when climbing steep inclines or at low
speeds. This prevents the gearbox from
changing up and keeps the gearbox oil
cooler.
• Do not use a higher manual gear than the
engine can "handle". It is not always eco-
nomical to drive in high gears.

• Avoid driving with a trailer on inclines of
more than 15 %.
Assisted starting with a trailer
Cars equipped with a V8 engine have an inte-
grated function which reduces the risk of sig-
nificant jerking and wheelspin when starting
with a trailer hitched to the car.
Activating
To activate, the cables from the trailer must
be connected to the trailer socket which is
fitted beside the towbar, see page 137.
Deactivating
Unplug the cables from the electrical socket.
NOTE
The function is also activated when any oth-
er electrical equipment is plugged into the
trailer socket, and the car then accelerates
more gently when pulling away.
Levelling (option on cars seating five,
standard on cars seating seven)
If your car is equipped with automatic level-
ling, the rear suspension always retains the
correct ride height regardless of load. When
the car is stationary, the rear suspension
sinks. This is completely normal. When start-
ing with a load, the level is pumped up after a
certain distance.
