All Wheel Drive (option) 
All Wheel Drive (AWD) - general information 
Your Volvo can be equipped with permanent All Wheel Drive (option), wh\
ich means that power is distributed 
automatically between the front and rear wheels. Under normal driving co\
nditions, most of the engine's power is directed 
to the front wheels. However, if there is any tendency for the front whe\
els to spin, an electronically controlled coupling 
distributes power to the wheels that have the best traction.
Tire dimensions 
Volvo 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 m\
ixed 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 placards, located on the driver's side B-pillar (the structura\
l 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 Can\
adian models.
Temporary Spare 
The 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. \
(80km/h) or for distances greater than 50 miles 
(80 km). 
Never install snow chains on a temporary spare.

Before a long distance trip 
It is always worthwhile to have your vehicle checked at a Volvo retailer\
 before driving long distances. Your retailer will 
also be able to supply you with bulbs, fuses, spark plugs and wiper blad\
es for your use in the event that problems occur. 
As a minimum, the following items should be checked before any long trip\
: 
l     Check that engine runs smoothly and that fuel consumption is normal. 
l     Check for fuel, oil, and fluid leakage. 
l     Check transmission oil level1. 
l     Check condition of drive belts. 
l     Check state of the battery's charge. 
l     Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures. 
l     The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only. 
l     Check all lights, including high beams. 
l     Reflective warning triangles are legally required in some states/provinc\
es. 
l     Have a word with your Volvo retailer if you intend to drive in countries\
 where it may be difficult to obtain the correct 
fuel. 
l     Consider your destination. If you will be driving through an area where \
snow or ice are likely to occur, consider snow 
tires. 
1. To prevent injury from contact with hot surfaces, do not inspect your\
 vehicle's transmission fluid yourself. Have your vehicle's 
transmission fluid level inspected by a qualified Volvo service technici\
an.

General information 
Your vehicle is equipped with tires according to the vehicle's tire info\
rmation placard on the B-pillar 
(the structural member at the side of the vehicle, at the rear of the d\
river's door opening), or on the inside 
of the fuel filler door on Canadian models. 
The tires have good road holding characteristics and offer good handling\
 on dry and wet surfaces. It 
should be noted however that the tires have been developed to give these\
 features on snow/ice-free 
surfaces. 
Certain models are equipped with "all-season" tires, which provide a som\
ewhat higher degree of road 
holding on slippery surfaces than tires without the "all-season" rating.\
 However, for optimum road

General information 
WARNING! 
l     The wheel and tire sizes for your Volvo are specified to meet stringent \
stability and handling 
requirements. Unapproved wheel/tire size combinations can negatively aff\
ect your vehicle's stability 
and handling. Approved tire sizes are shown in the Tire inflation pressu\
re tables on 
page 154. 
l     Any damage caused by installation of unapproved wheel/tire size combinat\
ions 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 perishable 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 age 
Tires degrade over time, even when they are not being used. It is recomm\
ended that tires generally be 
replaced after 6 years of normal service. Heat caused by hot climates, f\
requent 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 th\
e illustration above). 
A tire with e.g., visible cracks or discoloration should be replaced imm\
ediately.
Improving tire economy: 
l     Maintain correct tire pressure. See the tire pressure table on page 154. 
l     Drive smoothly: avoid fast starts, hard braking and tire screeching. 
l     Tire wear increases with speed. 
l     Correct front wheel alignment is very important. 
l     Unbalanced wheels impair tire economy and driving comfort. 
l     Tires must maintain the same direction of rotation throughout their life\
time.
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\

- Add air to reach the recommended air pressure. 
- Replace the valve cap. 
- Repeat this procedure for each tire, including the spare. 
- Visually inspect the tires to make sure there are no nails or other ob\
jects embedded that could puncture 
the tire and cause an air leak. 
- Check the sidewalls to make sure there are no gouges, cuts, bulges or \
other irregularities.
NOTE: 
l     If you overfill the tire, release air by pushing on the metal stem in th\
e center of the valve. Then 
recheck the pressure with your tire gauge. 
l     Some spare tires require higher inflation pressure than the other tires.\

Tire Pressure Monitoring System (TPMS) - option 
The tire pressure monitoring system uses sensors mounted in the tire val\
ves to check inflation pressure 
levels. When the vehicle is moving at a speed of approximately 20 mph (\
30 km/h) or faster, these 
sensors transmit inflation pressure data to a receiver located in the ve\
hicle. 
USA - FCC ID: MRXTG315AM04  
This device complies with part 15 of the FCC rules. Operation is subject\
 to the following conditions: 
(1) This device may not cause harmful interference, and (2) this dev\
ice must accept any interference 
received, including interference that may cause undesired operation. 
When low inflation pressure is detected, TPMS will light up the tire pre\
ssure warning light (
 ) (also 
referred to as a telltale) in the instrument panel, and will display a \
message in the text window. The 
wording of this message is determined by the degree of inflation pressur\
e loss.
NOTE: If a fault occurs in TPMS, the tire pressure warning light will flash f\
or approximately 1 minute 
and TIRE PRESS SYST SERVICE REQUIRED will be displayed.

Each tire, including the spare (if provided), should be checked monthl\
y when cold and inflated to the 
inflation pressure recommended by the vehicle manufacturer on the vehicl\
e placard or tire inflation 
pressure label. (If your vehicle has tires of a different size than the\
 size indicated on the vehicle placard 
or tire inflation pressure label, you should determine the proper tire i\
nflation pressure for those tires.) 
 
As an added safety feature, your vehicle has been equipped with a tire p\
ressure monitoring system 
(TPMS) that illuminates a low tire pressure telltale when one or more \
of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale illuminates, \
you should stop and check your 
tires as soon as possible, and inflate them to the proper pressure. Driv\
ing on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. \
Under-inflation also reduces fuel 
efficiency and tire tread life, and may affect the vehicle's handling an\
d stopping ability. 
 
Please note that the TPMS is not a substitute for proper tire maintenanc\
e, and it is the driver's 
responsibility to maintain correct tire pressure, even if under-inflatio\
n has not reached the level to trigger 
illumination of the TPMS low tire pressure telltale. 
 
Your vehicle has also been equipped with a TPMS malfunction indicator to\
 indicate when the system is 
not operating properly. The TPMS malfunction indicator is combined with \
the low tire pressure telltale. 
When the system detects a malfunction, the telltale will flash for appro\
ximately one minute and then 
remain continuously illuminated. This sequence will continue upon subseq\
uent vehicle start-ups as long 
as the malfunction exists. When the malfunction indicator is illuminated\
, the system may not be able to 
detect or signal low tire pressure as intended. TPMS malfunctions may oc\
cur for a variety of reasons, 
including the installation of replacement or alternate tires or wheels o\
n the vehicle that prevent the 
TPMS from functioning properly. Always check the TPMS malfunction tellta\
le after replacing one or 
more tires or wheels on your vehicle to ensure that the replacement or a\
lternate tires and wheels allow 
the TPMS to continue to function properly.
NOTE: 
l     TPMS indicates low tire pressure but does not replace normal tire mainte\
nance. For information on 
correct tire pressure, please refer to the table on 
page 154, or consult your Volvo retailer.
Erasing warning messages 
When a low tire pressure warning message has been displayed, and the tir\
e pressure warning light has 
come on:

Tire Pressure Monitoring System (TPMS) - option 
- Use a tire pressure gauge to check the inflation pressure of all four \
tires. 
- Re-inflate the tire(s) to the correct pressure (consult the tire pr\
essure placard or the table on 
page 154).

- Drive the vehicle for several minutes at a speed of 20 mph (30 km/h)\
 or faster.
This will erase the warning text and the warning light will go out. 
WARNING! 
Incorrect inflation pressure could lead to tire failure, resulting in a \
loss of control of the 
vehicle. 
Changing wheels with TPMS 
Please note the following when changing or replacing the factory install\
ed TPMS wheels/ tires on the 
vehicle: 
l     Only the factory-mounted wheels are equipped with TPMS sensors in the va\
lves. 
l     If the vehicle is equipped with a temporary spare tire, this tire does n\
ot have a TPMS sensor. 
l     If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SY\
ST SERVICE 
REQUIRED will be displayed each time the vehicle is driven above 25 mph \
(40 km/h) for 10 minutes or 
more. 
l     Once TPMS sensors are properly installed, the warning message should not\
 reappear. 
l     Volvo recommends that TPMS sensors be fitted on all wheels used on the v\
ehicle. Volvo does not 
recommend moving sensors back and forth between sets of wheels. 
CAUTION! 
When inflating tires with TPMS valves, press the pump's mouthpiece strai\
ght onto the valve to help 
avoid bending or otherwise damaging the valve. 
Adjusting (recalibrating) TPMS
1 
TPMS can be adjusted, or recalibrated, in order to help adapt the system\
 to different inflation pressures, 
for example when transporting heavy loads. To do so: 
- Switch off the engine. 
- Inflate the tires to the desired pressure. 
- Turn the ignition key to position I or II. 
- Turn the thumbwheel on the left steering wheel lever until the text TI\
RE PRESSURE CALIBRATION 
is displayed. 
- Press in and hold the Reset button (see the illustration on 
page 50) until TIRE PRESSURE 
CALIBRATED is displayed. This completes the procedure.
NOTE: TPMS should be recalibrated each time tire inflation pressure is change\
