2007 Volvo XC90
Difficult driving conditions
Driving on rough/unpaved surfaces
The Volvo XC90 is designed primarily for on-road driving, and it has exc\
ellent handling characteristics on very rough or
unpaved roads.
When driving on poorly maintained or unpaved roads, please keep the foll\
owing in mind:
l Reduce speed on rough surfaces to minimize possible damage to the vehicl\
e's underbody.
l When driving on soft surfaces such as dry sand or snow, try to avoid sto\
pping if at all possible.
WARNING!
Avoid driving diagonally across steep inclines as this could increase th\
e risk of a roll-over. Try to drive straight up or
down the slope.
If the road is very steep, avoid turning the vehicle around to help avoi\
d the risk of rolling over. Back the vehicle up or
down the incline instead.
NOTE: Avoid driving on steep inclines if the fuel tank is nearly empty. If th\
e flow of fuel to the engine is interrupted due
to the vehicle's angle of inclination, this could result in damage to th\
e three-way catalytic converter. We recommend
keeping the fuel tank at least half full when driving on steep inclines.\
Driving through water
The vehicle can be driven through water up to a depth of approximately 1\
8 inches (48 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 wa\
ter.
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!
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 18 in (48 cm), wate\
r may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorte\
n the service life of these components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This could result in
electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the car towed out
of the water.

Towing a trailer
The maximum weights recommended by Volvo for trailers with brakes are shown in the table below.
NOTE:
l Recommended hitch tongue load: not more than 10% of the trailer's weight\
. The trailer load should be positioned
so that it does not shift and the tongue load should be 10% of the trail\
er's weight. However, the tongue load should not
exceed the maximum permissible weights indicated in the table above.
l When towing trailers without brakes, the maximum permissible trailer weight is 1,700 lbs (750 kg).\
l If necessary, redistribute the weight of any cargo in the trailer to avo\
id excessive weight on the trailer hitch.
l The maximum trailer weight listed in the table for All Wheel Drive model\
s, 5,000 lbs (2250 kg) is only applicable when
there are not more than two occupants in the vehicle, in the front seats\
, with a combined weight of 300 lbs (135 kg), with
no other cargo in the vehicle.
l The maximum weight listed for Front Wheel Drive models, 4,000 lbs (1800\
kg) is only applicable when there are not
more than four occupants in the vehicle, in the front seats and second r\
ow of seats, with a combined weight of 600 lbs (270
kg), with no other cargo in the vehicle.

Towing a trailer
l Please be aware that the load on the trailer hitch is part of the vehicl\
e's total load carrying capacity. The amount of cargo
in the vehicle and the trailer must be limited so that the gross vehicle\
weight and maximum permissible rear axle weight
(see
page 209) are not exceeded.
l Vehicles used for towing a trailer on a regular basis, or for long-dista\
nce highway towing should be equipped with an
automatic transmission oil cooler and Volvo's automatic self-leveling sy\
stem for the rear suspension. Consult your Volvo
retailer.
l Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
l Increase tire pressure to recommended full inflation pressure. See chapt\
er "Wheels and tires."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1,000 km).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should be closely

Load carrier cover
The vehicle's ignition key or the stud on the edge of the supplied torqu\
e wrench can be used to undo or tighten the cover.
Turn a quarter turn (90 degrees). See illustration.

Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce freeze protection. This
gives protection against freezing down to -31°F (-35°C). See sec\
tion "Coolant". The use of "recycled" antifreeze is not
approved by Volvo. Different types of antifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer stocks plenty of
Volvo engine coolant to protect your vehicle during cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. \
In addition, in extremely
cold weather conditions it is worthwhile to add fuel line de-icer before\
refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weat\
her starting as well
as decreasing fuel consumption while the engine is warming up. For winte\
r use, 5W-30 oil, particularly the synthetic type
1,
is recommended. Be sure to use good quality oil but do not use cold-weat\
her oil for hard driving or in warm weather. See
section "Engine oil" for more information.
l The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc\
. are used more
often. Moreover, the capacity of the battery decreases as the temperatur\
e drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check th\
e state of charge more frequently and spray an
antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels and tires."\
l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 188 for the
location of the washer fluid reservoir). This is important since dirt i\
s often splashed on the windshield during winter
driving, requiring the frequent use of the washers and wipers. Volvo Was\
her Solvent should be diluted as follows:
- Down to 14° F (-10° C): 1 part washer solvent and 4 parts water
- Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
- Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
- Down to -18° F (-28° C): 1 part washer solvent and 1 part water
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
