WARNING
•When the vehicle is being towed, the
ignition should be in mode II (in mode I,
all of the vehicle's airbags are deacti-
vated). See page 83 for more informa-
tion about ignition modes.
•Never remove the remote key from the
ignition slot when the vehicle is being
towed. For vehicles with keyless drive,
the remote key must remain inside the
vehicle.
•The power brakes and power steering
will not function when the engine is not
running. Approximately 5 times more
pressure will be required on the brake
pedal and the steering wheel will be
considerably harder to turn.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.
Towing the vehicle
1. With the remote key fully pressed into the
ignition slot1, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the ignition
slot
2 for the entire time that the vehicle is
being towed.
3. Keep the tow rope taut when the towing
vehicle slows down by applying light pres-
sure on the brake pedal. This will help pre-
vent jarring movements of the vehicle
being towed.
4. Be prepared to apply the brakes to stop the
vehicle being towed.
CAUTION
General towing precautions:
•Please check with state and local
authorities before attempting this type
of towing, as vehicles being towed are
subject to regulations regarding maxi-
mum towing speed, length and type of
towing device, lighting, etc.
•If the vehicle's battery is dead, attach
jumper cables (see page 116) to provide
current for releasing the electric parking
brake and to move the gear selector
from the P position to N. If this is not
possible, see page 120 for information
about manually overriding the shiftlock
system to move the gear selector from
P to N.
•Maximum speed: 50 mph (80 km/h). Do
not exceed the maximum allowable
towing speed.
•Maximum distance with front wheels on
ground: 50 miles (80 km).
•The vehicle should only be towed in the
forward direction.
1Not necessary in vehicles with the optional keyless drive.2For vehicles with the the optional keyless dirive, the remote key must be in the vehicle.

Having the vehicle towed by a tow
truck
Call for professional help from an authorized
towing company.Volvo recommends the use of
flat bed equipment.
CAUTION
•The vehicle should always be towed in
the forward direction.
•Vehicles with All Wheel Drive (AWD)*
that are being towed with the front
wheels off the ground should not be
towed at a speed above approx. 45 mph
(70 km/h) and should not be towed far-
ther than 30 miles (50 km).
•If the vehicle is being towed on a flat bed
truck, the towing eyelet must not be
used to pull the vehicle up onto the flat
bed or to secure the vehicle on the flat
bed. Consult the tow truck operator.

Introduction
Your vehicle is equipped with tires according
to the vehicle's tire information placard on the
B-pillar (the structural member at the side of
the vehicle, at the rear of the driver's door
opening).
CAUTION
Some Volvo models are equipped with an
Ultra High Performance tire and wheel com-
bination designed to provide maximum dry
pavement performance with consideration
for hydroplaning resistance. They may be
more susceptible to road hazard damage
and, depending on driving conditions, may
achieve a tread life of less than 20,000 miles
(30,000 km). Even if this vehicle is equipped
with Volvo’s advanced AWD or DSTC sys-
tem, these tires are not designed for winter
driving, and should be replaced with winter
tires when weather conditions dictate.
The tires have good road holding characteris-
tics and offer good handling on dry and wet
surfaces. It should be noted however that the
tires have been developed to give these fea-
tures on snow/ice-free surfaces.
Most models are equipped with "all-season"
tires, which provide a somewhat higher degree
of road holding on slippery surfaces than tireswithout the "all-season" rating. However, for
optimum road holding on icy or snow-covered
roads, we recommend suitable winter tires on
all four wheels.
When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of altering
the car's roadholding and handling characte-
ristics.
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., 1510 means
that the tire illustrated was manufactured dur-
ing week 15 of 2010).
Tire rotationYour vehicle has no required tire rotation. Tire
wear is affected by a number of factors such
as tire inflation, ambient temperature, driving
style, etc.
NOTE
•If the tires are rotated, they should only
be moved from front to rear or vice
versa. They should never be rotated left
to right/right to left.
•Ideally, tire rotation should be done the
first time after approximately 3,000
miles (5,000 km) and thereafter at
6,000-mile (10,000-km) intervals. Some
customers find that tire rotation may
help to get extra mileage from tire life.
•Tire rotation should only be performed
if front/rear tire wear is fairly even and
tread height is above 1/16" (1.6 mm).
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.
The temporary spare

at 6-year intervals, even if it has never been
used.
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.
Tread wear indicator
G021829
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 trac-
tion.
When replacing worn tires, it is recommended
that the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of the
same make (manufacturer) will prevent altera-
tion of the driving characteristics of the vehicle.
Improving tire economy
•Maintain correct tire pressure. See the tire
inflation table on page 299.
•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.
Summer and winter tires
G021778
The arrows shows the direction of rotation of the
tire
•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.

Storing wheels and tiresWhen storing complete wheels (tires mounted
on rims), they should be suspended off the
floor or placed on their sides on the floor.
Tires not mounted on rims should be stored on
their sides or standing upright, but should not
be suspended.
CAUTION
Tires should preferably be stored in a cool,
dry, dark place, and should never be stored
in close proximity to solvents, gasoline, oils,
etc.
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.
•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.

Tire inflation

297 Inflation placard
G032521
Tire inflation placard
Tire inflationCheck tire inflation pressure regularly.
See the tire inflation table on page 299. 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 placard indicates the des-
ignation of the factory-mounted tires on your
vehicle, as well as load limits and inflation pres-
sure.
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 pres-
sure fluctuates with seasonal changes
in temperature. Always check tire pres-
sure 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 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 pressure
Cold tires
Inflation 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.

Tire inflation

298
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:1. Remove the cap from the valve on one tire,
then firmly press the tire gauge onto the
valve.
2. Add air to reach the recommended air
pressure.
3. Replace the valve cap.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded
that could puncture the tire and cause an
air leak.
5. Check the sidewalls to make sure there are
no gouges, cuts, bulges or other irregular-
ities.6. Repeat this procedure for each tire, includ-
ing the spare.
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 pressure table on page
299 or see the inflation pressure plac-
ard.
