177 Snow chains
Snow chains can be used on your Volvo with
the following restrictions:•
Snow chains should be installed on front
wheels only. Use only Volvo approved
snow chains.
•
If accessory, aftermarket or "custom" tires
and wheels are installed and are of a size
different than the original tires and wheels,
chains in some cases CANNOT be used.
Sufficient clearances between chains and
brakes, suspension and body components
must be maintained.
•
Some strap-on type chains will interfere
with brake components and therefore
CANNOT be used.
Consult your Volvo retailer for additional snow
chain information.
CAUTION
•
Check local regulations regarding the
use of snow chains before installing.
•
Always follow the chain manufacturer's
installation instructions carefully. Install
chains as tightly as possible and
retighten periodically.
•
Never exceed the chain manufacturer's
specified maximum speed limit. (Under
no circumstances should you exceed
31 mph (50 km/h).
•
Avoid bumps, holes or sharp turns
when driving with snow chains.
•
The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
Snow tires, studded tiresTires for winter use:•
Owners who live in or regularly commute
through areas with sustained periods of
snow or icy driving conditions are strongly
advised to fit suitable winter tires to help
retain the highest degree of traction.
•
It is important to install winter tires on all
four wheels to help retain traction during
cornering, braking, and accelerating. Fail-ure to do so could reduce traction to an
unsafe level or adversely affect handling.
•
Do not mix tires of different design as this
could also negatively affect overall tire road
grip.
•
Winter tires wear more quickly on dry roads
in warm weather. They should be removed
when the winter driving season has ended.
•
Studded tires should be run-in 300–
600 miles (500–1000 km) during which the
car should be driven as smoothly as pos-
sible to give the studs the opportunity to
seat properly in the tires. The tires should
have the same rotational direction
throughout their entire lifetime.NOTE
Please consult state or provincial regula-
tions restricting the use of studded winter
tires before installing such tires.

07 Wheels and tiresTemporary spare
07178
Temporary spareThe spare tire in your car is called a "Temporary
Spare".
Recommended tire pressure (see the placard
on the B-pillar or on the fuel filler door) 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 your Volvo retailer.
WARNING
Current legislation prohibits the use of the
"Temporary Spare" tire other than as a tem-
porary replacement for a punctured tire. It
must be replaced as soon as possible by a
standard tire. Road holding and handling
may be affected with the "Temporary
Spare" in use. Do not exceed a speed of
50 mph (80 km/h) with the "Temporary
Spare" in use.
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 seri-
ously damage your car's transmission.

Wheel nuts

179 Wheel nuts
G020324
Low nut.High nut.
There are two different types of wheel nut,
depending on whether the wheels are steel or
aluminum.
Steel rims – low nutSteel rims are normally secured using the low
type of nut, although steel rims may also use
the high type.
WARNING
Never use the short type of nut for alumi-
nium wheels. This could cause the wheel to
come loose.Aluminum wheels – high nutOnly the high type of nut can be used for alu-
minum wheels. This is considerably different
from other types of nut because it has a rotat-
ing conical thrust washer.
NOTE
This nut can also be used on steel wheels.Lockable wheel nutIf steel wheels with lockable wheel nuts are
used in combination with wheel covers, the
lockable wheel nut must be fitted to the stud
nearest the air valve. The wheel cover cannot
otherwise be installed on the wheel.

07 Wheels and tiresTire rotation

G020325
The arrows shows the direction of rotation of the
tireSummer and winter tires•
When switching between summer and
winter tires, mark the tires to indicate
where they were mounted on the car, e.g.,
LF = left front, RR = right rear
•
Tires with tread designed to roll in only one
direction are marked with an arrow on the
sidewall.
•
Incorrectly mounted tires impair the car's
braking properties and ability to force
aside rain, snow and slush.
•
The tires with the most tread should always
be at the rear (to reduce the risk of skid-
ding).
•
Contact a Volvo workshop if you are
unsure about the tread depth.
Tire rotationYour vehicle has no recommended tire rota-
tion. The following information is intended to
help you understand why.Tread setAs a tire ages and the rubber cures, front and
rear tires set at different angles. Therefore, if
tires are rotated, the tread will eventually set at
an angle that is a compromise. Even if ride,
handling, and road noise may still seem
acceptable, they may not be optimal. Further,
tires that are rotated, but not on a regular basis,
may actually cause more tire noise, faster tire
wear, and unpleasant changes in steering feel
and vehicle handling.
A tire that can fully adapt to its position will
provide better steering feel, lower tire noise,
and better fuel economy.Braking stability performanceYour vehicle is driven mainly by the front tires,
which will wear faster. This can be beneficial.
Having more tread on the rear tires will help
reduce oversteer. Oversteer is when a vehicle
wants to keep turning because of momentum
and dynamic forces on its suspension.Suspension wear diagnosticsEvery suspension needs periodic inspection
and maintenance. A tire's wear pattern can bean aid in detecting a suspension problem. Each
tire, if left in place, tells a story about the sus-
pension. Tire rotation, on the other hand, could
make suspension wear harder to detect. Early
detection is very important, because suspen-
sion problems can make tire wear worse.
If you do rotate your tires…Please follow the tire manufacturer's recom-
mendations, as outlined in the tire manufactur-
ers tire warranty pamphlet.
Your Volvo retailer can also provide guidance
based on your particular driving circumstan-
ces.

The spare tire, jack, and crank are located
under the carpet on the floor of the cargo area.
To change a tire:
1. Apply the parking brake.
2.
Put the gear selector in Park (P) or reverse
on models with a manual transmission.
3. Block the wheels that are on the ground
with wooden blocks or large stones.
4. Remove the wheel cap (where applicable)
using the lug wrench in the tool bag.
G020332
5. With the car still on the ground, use the lug
wrench to loosen the wheel nuts 1/2–1 turn
by exerting downward pressure. Turn the
nuts counterclockwise to loosen.
6. There are two jack attachment points on
each side of the car. Position the jack cor-
rectly in the attachment (see the illustration)
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. Before raising the car,
check that the jack is still correctly posi-
tioned in the attachment.

5. Install the wheel cap (where applicable).Returning the jack to its storage space
G029335
The jack (certain models) and tools should be
returned to their correct storage places after
use.•
On vehicles equipped with a jack and
spare wheel, the jack should be cranked
down to the position shown in the illustra-
tion.
•
On vehicles equipped with the tire sealing
system, the jack should be cranked down
as far as possible and returned to its stor-
age position in the foam block.WARNING

Tire Sealing System
07``183 Introduction
Certain models are equipped with a tire sealing
system that enables you to temporarily seal a
hole in the tread surface and re-inflate a flat tire,
or to adjust a tire’s inflation pressure.
The system consists of an air compressor, a
container for the 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.
The 12-volt sockets are located in the front
tunnel console and on the rear side of the tun-
nel console, in the rear seat.Accessing the tire sealing systemThe tire sealing system is stowed under the
floor of the cargo area. To access it:
1. Fold up or remove any carpet or other floor
covering.
2. Open the floor hatch.
3. Lift out the tire sealing system.
NOTE
•
The tire sealing system is only intended
to seal holes on the tire’s tread area, not
the sidewall.
•
Tires with large holes or tears cannot be
repaired with the tire sealing system.WARNING
•
After using the tire sealing system, the
vehicle should not be driven farther than
approximately 120 miles (200 km).
•
Have the tire inspected by a trained and
qualified Volvo service technician as
soon as possible to determine if it can
be permanently repaired or must be
replaced.
•
The vehicle should not be driven faster
than 50 mph (80 km/h) while using a tire
that has been temporarily repaired with
the tire sealing system.
•
After using the tire sealing system, drive
carefully and avoid abrupt steering
maneuvers and sudden stops.

WARNING
Please keep the following points in mind
when using the tire sealing system:•
The sealing compound bottle (no. 8 in
the illustration) contains 1.2-Ethanol
and natural rubber-latex. These sub-
stances are harmful if swallowed.
•
The contents of this bottle may cause
allergic skin reactions or otherwise be
potentially harmful to the skin, the cen-
tral nervous system, and the eyes.
Precautions:
•
Keep out of reach of children.
•
Do not ingest the contents.
•
Avoid prolonged or repeated contact
with the skin.
•
Hands should be washed thoroughly
after handling.
First aid:
•
Skin: Wash affected areas of skin with
soap and water. Get medical attention
if symptoms occur.
•
Eyes: Flush with plenty of water for least
15 minutes, occasionally lifting the
upper and lower eyelids. Get medical
attention if symptoms occur.
•
Inhalation: Move the person to fresh air.
If irritation persists, get medical atten-
tion.
Tire sealing system–temporarily
repairing a flat tire
G014338
Temporarily repairing a flat tire is done in two
stages:
•
Stage 1: 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.NOTE
Do not remove any foreign objects (nails,
etc.) from the tire before using the sealing
system.•
Stage 2: The tire’s inflation pressure is
checked and adjusted if necessary.WARNING
•
Never leave the tire sealing system
unattended when it is operating.
•
Keep the tire sealing system away from
children.
•
Be sure the vehicle is parked safely off
the road and away from moving traffic.
•
Apply the parking brake.
Stage 1: Sealing the hole1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it
to the steering wheel hub where it will be
clearly visible to the driver.
