Fuses
Replacing fuses
There are relay/fuse boxes located in the engine compartment, the passenger compartment, and the trunk.
If an electrical component fails to function, this may be due to a blown fuse. The easiest way to see if a fuse is blown
is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, special fuse removal tools are located on the inside of the
fuse box covers.
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
If the wire is broken, insert a new fuse of the same color and amperage (written on the fuse).
If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvo service technician.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the following pages. Doing so could
seriously damage or overload the vehicle's electrical system.

qualified Volvo service technician.
There is a special fuse removal tool on the underside of the cover.

The tires have wear indicator strips running across or parallel to the tread. The letters TWI are printed on the side of
the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire
should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.
WARNING
The wheel and tire sizes for your Volvo are specified to meet stringent stability and handling requirements.
Unapproved wheel/tire size combinations can negatively affect your vehicle's stability and handling. Approved tire
sizes are shown in the Tire inflation pressure tables beginning on page 240
.
Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new
vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such
installations.
236 06 Maintenance and specifications
Wheels and tires
New tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year (Department of
Transportation (DOT) stamp) 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 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).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy
Maintain correct tire pressure. See the tire pressure tables beginning on page 240.
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.
237 06 Maintenance and specifications
Wheels and tires
Tire inflation
Tire inflation
Check tire inflation pressure regularly.
Tables listing the recommended inflation pressure for your vehicle can be found on pages 240 and 241
. A tire inflation
pressure placard is also located on the driver's side Bpillar (the structural member at the side of the vehicle, at the rear
of the driver's door opening). This placard indicates the designation of the factory-mounted tires on your vehicle, as
well as load limits and inflation pressure.
NOTE
The placards shown indicate inflation pressure for the tires installed on the vehicle at the factory only.
A certain amount of air seepage from the tires occurs naturally and tire pressure fluctuates with seasonal changes
in temperature. Always check tire pressure regularly.
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 pressure gauge, as automatic service station gauges may be inaccurate.
Use the recommended cold inflation pressure 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 "blowout," with unexpected loss of vehicle control and increased risk of injury.
Under-inflated tires reduce the load carrying capacity of your vehicle.

The tire pressure monitoring system uses sensors mounted in the tire valves 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 vehicle.
NOTE
USA - FCC ID: KR5S122780002
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 device must accept any interference received, including interference
that may cause undesired operation.
When low inflation pressure is detected, TPMS will light up the tire pressure 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 pressure loss.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE PRESS
SYST SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle 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 inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure 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. Driving 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 and
stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation 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 approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent 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 occur for a variety of reasons, including the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
