or maximum permissible axle loads are not
exceeded.
Driving through water
The vehicle can be driven through water up
to a depth of approximately 9 in. (25 cm), at a
maximum speed of 6 mph (10 km/h).
Take particular care when driving through
flowing water.
Clean the electrical connections for trailer
wiring after driving in mud or water
When driving through water, maintain low
speed and do not stop in the water.
WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
• Engine damage will occur if water is
drawn into the air cleaner.
• If the vehicle is driven through water
deeper than 9 in (25 cm), water may enter
the differential and the transmission. This
reduces the oil's lubricating capacity and
may shorten the service life of these com-
ponents.
• Do not allow the vehicle to stand in water
up to the door sills longer than absolutely
necessary. This could result in electrical
malfunctions.
• If the engine has been stopped while the
vehicle is in water, do not attempt to restart
the engine. Have the vehicle towed out of
the water.
Engine and cooling system
Under special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine
and cooling system will overheat. Proceed as
follows to avoid overheating the engine.
• Maintain a low speed when driving with a
trailer up long, steep hills.
• Do not turn the engine off immediately you
stop after a hard drive.
• Remove any auxiliary lights from in front of
the grille when driving in hot weather
conditions.
05 During your trip
Driving recommendations
• Do not exceed engine speeds of 4500 rpm
if driving with a trailer in hilly terrain. The oil
temperature could become too high.
Conserving electrical current
Keep the following in mind to help minimize
battery drain:
• When the engine is not running, avoid
using ignition mode II. Many electrical
systems (the audio system, the optional
navigation system, power windows, etc)
will function in ignition modes 0 and I.
These modes reduce drain on the battery.
• Please keep in mind that using systems,
accessories, etc., that consume a great
deal of current when the engine is not
running could result in the battery being
completely drained.
• The optional 12 volt socket in the trunk
provides electrical current even with the
ignition switched off, which drains the
battery.
Before a long distance trip
It is always worthwhile to have your vehicle
checked by a trained and qualified Volvo ser-
vice technician before driving long distances.
Your retailer will also be able to supply you
with bulbs, fuses, spark plugs and wiper
blades for your use in the event that prob-
lems occur.
