more tread on the rear tires will help reduce oversteer. Oversteer is wh\
en a vehicle wants to keep turning
because of momentum and dynamic forces on its suspension.
Suspension wear diagnostics
Every suspension needs periodic inspection and maintenance. A tire's wea\
r pattern can be an aid in
detecting a suspension problem. Each tire, if left in place, tells a sto\
ry about the suspension. Tire rotation,
on the other hand, could make suspension wear harder to detect. Early de\
tection is very important,
because suspension problems can make tire wear worse.
If you do rotate your tires...
Please follow the tire manufacturer's recommendations, as outlined in th\
e tire manufacturers tire warranty
pamphlet.

Temporary spare
Temporary spare (option)
The spare tire in your car is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar) should be \
maintained irrespective of which
position on the car the temporary spare tire is used on.
In the event of damage to this tire, a new one can be purchased from you\
r Volvo retailer.
Location of the optional spare wheel and tools
The spare wheel is packed in a storage bag and is located under the pane\
l in the floor of the trunk.

On cars with a spare wheel, the jack and lug wrench are secured in a foa\
m plastic block placed in the
center of the wheel.
CAUTION
The car must not be driven with wheels of different dimensions or with a\
spare tire other than the one
that came with the car. The use of different size wheels can seriously d\
amage your car's transmission.
The retaining straps securing the spare wheel is attached to two eyelets\
in the floor of the spare wheel's
storage compartment.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire othe\
r than as a temporary
replacement for a punctured tire. It must be replaced as soon as possibl\
e by a standard tire. Road holding
and handling may be affected with the "Temporary Spare" in use. Do not e\
xceed 50 mph (80 km/h). Do
not drive farther than 50 miles (80 km) on a temporary spare tire.

Positioning the jack1
There are two jack attachment points on each side of the car.
6. Position the jack correctly in the attachment (see illustration abov\
e) and crank while simultaneously
guiding the base of the jack to the ground. The base of the jack must be\
flat on a level, firm, non-slippery
surface.
7. Before raising the car, check that the jack is still correctly positi\
oned in the attachment.
1Not included on models equipped with the tire sealing system.
WARNING
l The jack must correctly engage the jack attachment.
l Be sure the jack is on a firm, level, non-slippery surface.
l Never allow any part of your body to be extended under a car supported b\
y a jack.
l Use the jack intended for the car when changing a tire. For any other jo\
b, use stands to support the
car.
l Apply the parking brake and put the gear selector in the Park (P) position.
l Block the wheels standing on the ground, use rigid wooden blocks or larg\
e stones.
l The jack should be kept well-greased.

9. Unscrew the wheel bolts completely and carefully remove the wheel so \
as not to damage the threads on
the studs.
Installing a wheel
1. Clean the contact surfaces on the wheel and hub.
2. Lift the wheel and place it on the hub.
3. Install the wheel nuts and tighten hand-tight. Using the lug wrench, \

Tire sealing system
Tire sealing system
Your vehicle is equipped with a tire sealing system that enables you to \
temporarily seal a hole in the tread
surface and reinflate a flat tire, or to adjust a tire's inflation press\
ure.
l The tire sealing kit is stowed behind the ski hatch in the center of the\
rear seat backrest.

The system consists of an air compressor, an integrated container for th\
e sealing compound, wiring to
connect the system to the vehicle's electrical system via one of the 12-\
volt sockets, and a hose used to
connect the system to the tire's inflation valve.
NOTE
The tire sealing system is only intended to seal holes on the tire's tre\
ad area, not the
sidewall.
l Tires with large holes or tears cannot be repaired with the tire sealing\
system.
WARNING
l After using the tire sealing system, the vehicle should not be driven fa\
rther than approximately 120
miles (200 km). Have the tire replaced as soon as possible.
l The vehicle should not be driven faster than 50 mph (80 km/h) while us\
ing a tire that has been
temporarily repaired with the tire sealing system.
l After using the tire sealing system, drive carefully and avoid abrupt st\
eering maneuvers and sudden
stops.
l A tire that has been temporarily inflated with the tire sealing kit cann\
ot be repaired and re-used. It
must be replaced.

Temporarily repairing a flat tire
Before using the tire sealing system, observe the following:
WARNING
l Never leave the tire sealing system unattended when it is operating.
l Keep the tire sealing system kit away from children.
l The vehicle's engine should be running when the tire sealing system is u\
sed to avoid battery drain.
Therefore, be sure the vehicle is parked in a well ventilated place befo\
re using the system.
l Be sure the vehicle is parked safely off the road and away from moving t\
raffic.
l Apply the parking brake.
l Do not remove any foreign objects (nails, etc.) from the tire.

Tire sealing system
Temporarily repairing a flat tire is done in two stages
l In the first stage, the hole is sealed by pumping sealing compound into \
the tire. The car is then driven a
short distance to distribute the sealing compound in the tire.
l In the second stage, the tire's inflation pressure is checked and adjust\
ed if necessary.
Stage 1 - Sealing the hole
Peel off the speed limit sticker (1) and affix it to the steering whee\
l hub where it will be clearly visible to
the driver.

1. Ensure that the orange switch (2) is in position 0 (the 0 side of \
the switch should be pressed down).
2. Pull out the electrical wire (5) and hose (4) from the side compa\
rtment (3).
3. Remove the valve cap from the tire's inflation valve and screw the ho\
se connector onto the valve as
tightly as possible by hand.
4. Connect the electrical wire to the nearest 12-volt socket in the vehi\
cle.
5. Release the safety catch (6) and turn the orange colored section of\
the sealing kit (7), which holds the
sealing compound container, 90 degrees until it clicks into the vertical\
position.
6. Start the vehicle's engine.
7. Start the tire sealing system's compressor by pressing the switch (2\
) to position I.
NOTE
The air pressure gauge (9) will temporarily show an increase in pressu\
re to approximately 88 psi (6 bar)
while the sealing compound is being pumped into the tire. The pressure s\
hould return to a normal level
after approximately one minute.
WARNING
l Contact with the sealing compound may cause skin irritation. If contact \
occurs, wash the affected area
immediately.
l Never stand next to the tire being inflated when the compressor is in op\
eration.
l If cracks, bubbles, etc. form on the tire, switch off the compressor imm\
ediately.
l If there is visible damage to the sidewall or the rim, the tire cannot b\
e repaired. The vehicle should
not be driven if this occurs.
Contact a towing service or Volvo On Call Roadside Assistance if applica\
ble.
8. Within seven minutes, inflate the tire to between 22 - 50 psi (1.8 -\
3.5 bar). Switch off the compressor
briefly to get a clear reading from the pressure gauge (9).
9. Disconnect the electrical wire from the 12-volt socket.
