WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment.•
If the tailgate must be kept open for any
reason, proceed as follows:
•
Close the windows
•
Set the ventilation system control to air
flow to floor, windshield and side win-
dows and blower control to its highest
setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend.
This ensures good stability and reduces the
risk of rear wheel skid. Remember that these
properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommendedpressure according to the vehicle load. See
"Tire pressure" section.
Loads should be distributed so that capacity
weight or maximum permissible axle loads are
not exceeded.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:•
When the engine is not running, avoid turn-
ing the ignition key to position II (see
page 135). Many electrical systems (the
audio system, the optional infotainment/
navigation systems, power windows, etc)
will function with the ignition key in position
I. This position reduces drain on the bat-
tery.
•
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.NOTE
A warning message will be displayed in the
text window in the instrument panel when
the battery charge is low.

06 Starting and drivingAll Wheel Drive (option)
06142
All Wheel Drive (AWD) – general
informationYour Volvo can be equipped with an electron-
ically controlled All Wheel Drive system
(option), which means that power is distributed
automatically between the front and rear
wheels. Under normal driving conditions, most
of the engine's power is directed to the front
wheels. However, if there is any tendency for
the front wheels to spin, an electronically con-
trolled coupling distributes power to the
wheels that have the best traction.Tire dimensionsVolvo recommends that you always drive on
tires of the same brand, size, construction
(radial), tread pattern, load-, speed-, traction-,
temperature-, and treadwear rating. Never
drive on mixed tires, except for brief periods
when the temporary spare tire is in use.
Always use properly inflated tires of correct
dimensions. Tire size and inflation pressures
are shown on the tire inflation pressure plac-
ards, located on the driver's side B-pillar (the
structural member at the side of the vehicle, at
the rear of the driver's door opening), or on the
inside of the fuel filler door on Canadian mod-
els.
Temporary SpareThe temporary spare tire is for temporary, low-
speed, short-distance use only. Replace it with
a full-sized tire as soon as possible. Do not
drive on the temporary spare at speeds above
50 m.p.h. (80 km/h).
NOTE
Never install snow chains on a temporary
spare.

06 Starting and drivingTowing a trailer
06152
NOTE
•
Recommended hitch tongue load:
not more than 10% of the trailer's
weight. The trailer load should be posi-
tioned 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 per-
missible weights indicated in the table
above.
•
When towing trailers without brakes,
the maximum permissible trailer weight
is 1,700 lbs (750 kg).
•
If necessary, redistribute the weight of
any cargo in the trailer to avoid exces-
sive weight on the trailer hitch.
•
The maximum trailer weight listed in the
table for All Wheel Drive models,
5,000 lbs (2250 kg) is only applicable
when there are not more than two occu-
pants in the vehicle, in the front seats,
with a combined weight of 300 lbs
(135 kg), with no other cargo in the vehi-
cle.
•
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 row of
seats, with a combined weight of
600 lbs (270 kg), with no other cargo in
the vehicle.
NOTE
•
Vehicles used for towing a trailer on a
regular basis, or for long-distance high-
way towing should be equipped with an
automatic transmission oil cooler and
Volvo's automatic self-leveling system
for the rear suspension. Consult your
Volvo retailer.
•
Volvo recommends the use of Volvo
trailer hitches that are specially
designed for the vehicle.
•
All Volvo models are equipped with
energy-absorbing shock-mounted
bumpers. Trailer hitch installation
should not interfere with the proper
operation of this bumper system.
•
Increase tire pressure to recommended
full inflation pressure. See chapter
"Wheels and tires."
•
When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•
Engine and transmission are subject to
increased loads. Therefore, engine
coolant temperature should be closely
watched when driving in hot climates or
hilly terrain. Use a lower gear and turn
off the air conditioner if the temperature
gauge needle enters the red range.

WARNING
•
The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unap-
proved wheel/tire size combinations
can negatively affect your vehicle's sta-
bility and handling. Approved tire sizes
are shown in the Tire inflation pressure
tables on pages 170 and 171.
•
Any damage caused by installation of
unapproved wheel/tire size combina-
tions will not be covered by your new
vehicle warranty. Volvo assumes no
responsibility for death, injury, or
expenses that may result from such
installations.
New tires
Remember that tires are per-
ishable goods. As of 2000, the
manufacturing week and year
will be indicated with 4 digits
(e.g. 1502 means that the tire
illustrated was manufactured
during week 15 of 2002).
Tire ageTires degrade over time, even when they are
not being used. It is recommended that tires
generally be replaced after 6 years of normal
service. Heat caused by hot climates, frequent
high loading conditions or Ultra Violet (U.V)
exposure can accelerate the aging process.
You should replace the spare tire when you
replace the other road tires due to the aging of
the spare.
A tire's age can be determined by the DOT
stamp on the sidewall (see the illustration
above).
A tire with e.g., visible cracks or discoloration
should be replaced immediately.Improving tire economy: •
Maintain correct tire pressure. See the tire
pressure table see page 170.
•
Drive smoothly: avoid fast starts, hard
braking and tire screeching.
•
Tire wear increases with speed.
•
Correct front wheel alignment is very
important.
•
Unbalanced wheels impair tire economy
and driving comfort.
•
Tires must maintain the same direction of
rotation throughout their lifetime.When replacing tires, the tires with the most
tread should be mounted on the rear wheels to
reduce the chance of oversteer during hard
braking.
Hitting curbs or potholes can damage the tires
and/or wheels permanently.

Tire inflation placards on U.S. modelsCheck tire inflation pressure regularly.
Tables listing the recommended inflation pres-
sure for your vehicle can be found on pages
170 and 171. A tire inflation pressure placard
is also located on the driver's side B-pillar (the
structural member at the side of the vehicle, at
the rear of the driver's door opening). This plac-
ard indicates the designation of the factory-
mounted tires on your vehicle, as well as load
limits and inflation pressure.
G032520
Tire inflation placard on Canadian models
NOTE
The placards shown indicate inflation pres-
sure for the tires installed on the vehicle at
the factory only.•
Use a tire gauge to check the tire inflation
pressure, including the spare, at least once
a month and before long trips. You are
strongly urged to buy a reliable tire pres-
sure gauge, as automatic service station
gauges may be inaccurate.
•
Use the recommended cold inflation pres-
sure for optimum tire performance and
wear.
•
Under-inflation or over-inflation may cause
uneven treadwear patterns.WARNING
•
Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation,
or "blow-out," with unexpected loss of
vehicle control and increased risk of
injury.
•
Under-inflated tires reduce the load car-
rying capacity of your vehicle.
When weather temperature changes occur, tire
inflation pressures also change. A 10-degree
temperature drop causes a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Check
your tire pressures frequently and adjust them
to the proper pressure, which can be found on
the vehicle's tire information placard or certifi-
cation label.Checking tire pressureA certain amount of air seepage from the tires
occurs naturally and tire pressure fluctuates
with seasonal changes in temperature. Always
check tire pressure regularly.Cold tiresInflation pressure should be checked when the
tires are cold.

The tires are considered to be cold when
they have the same temperature as the sur-
rounding (ambient) air.
This temperature is normally reached after the
vehicle has been parked for at least 3 hours.
After driving a distance of approximately 1 mile
(1.6 km), the tires are considered to be hot. If
you have to drive farther than this distance to
pump your tire(s), check and record the tire
pressure first and add the appropriate air pres-
sure when you get to the pump.
If checking tire pressure when the tire is hot,
never "bleed" or reduce air pressure. The tires
are hot from driving and it is normal for pres-
sures to increase above recommended cold
pressures. A hot tire at or below recommended
cold inflation pressure could be significantly
under-inflated.To check inflation pressure:•
Remove the cap from the valve on one tire,
then firmly press the tire gauge onto the
valve.
•
Add air to reach the recommended air
pressure.
•
Replace the valve cap.
•
Repeat this procedure for each tire, includ-
ing the spare.
•
Visually inspect the tires to make sure there
are no nails or other objects embeddedthat could puncture the tire and cause an
air leak.
•
Check the sidewalls to make sure there are
no gouges, cuts, bulges or other irregular-
ities.NOTE
•
If you overfill the tire, release air by
pushing on the metal stem in the center
of the valve. Then recheck the pressure
with your tire gauge.
•
Some spare tires require higher inflation
pressure than the other tires. Consult
the tire inflation tables on pages 170
and 171 or see the inflation pressure
placard.
