165 Loading the vehicle
Your vehicle's load-carrying capacity is affec-
ted by factors such as:
•the number of passengers
•tire inflation
•the amount of optional or accessory equip-
ment installed
•the amount of cargo.
See the chapter "Wheels and tires" for more
detailed information.
Before loading the car, turn off the engine, and
apply the parking brake when loading or
unloading long objects. The gear selector can
be inadvertently knocked out of position by
long cargo, causing the car to move.
Keep the following in mind when
loading the vehicle:
•Load objects in the trunk against the rear
seat backrest.
•Load heavy cargo as low as possible.
•Center wide loads.
•Secure all cargo with restraining straps
anchored to the load securing eyelets.
•Cover sharp edges on the load.
•Seats can be folded down and head
restraints removed to extend the cargo
compartment, see page 115.
WARNING
•Remember that an object weighing
44 lbs (20 kg) produces a force of
2,200 lbs (1,000 kg) in a head-on colli-
sion at 30 mph (50 km/h)!
•When the rear backrest(s) are folded
down, the vehicle should not be loaded
to a level higher than 2 in. (5 cm) below
the upper edge of the rear side win-
dows. Objects placed higher than this
level could impede the function of the
Volvo Inflatable Curtain.
Load carriers (accessory)
Load carriers are available as Volvo accesso-
ries. Follow the installation instructions sup-
plied with the load carriers.
Observe the following points when using load
carriers:
•To avoid damaging your car and to achieve
maximum safety when driving, we recom-
mend using the load carriers that Volvo has
developed especially for your car.
•Volvo-approved removable roof racks are
designed to carry the maximum allowable
roof load for this vehicle: 165 lbs (75 kg).
For Non-Volvo roof racks, check the man-
ufacturer's weight limits for the rack.
•Never exceed the rack manufacturer's
weigh limits and never exceed the maxi-
mum rated roof load of 165 lbs (75 kg).
•Avoid single-point loads. Distribute loads
evenly.
•Place heavier cargo at the bottom of the
load.
•Secure the cargo correctly with appropri-
ate tie-down equipment.
•Check periodically that the load carriers
and load are properly secured.
•Remember that the car's center of gravity
and handling change when you carry a
load on the roof.
•The car's wind resistance and fuel con-
sumption will increase with the size of the
load.
•Drive smoothly. Avoid rapid starts, fast
cornering and hard braking.

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), or on the inside of the fuel filler door
on Canadian models.
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. As such, they
may be more susceptible to road hazard
damage and, depending on driving condi-
tions, may achieve a tread life of less than
20,000 miles (30,000 km). Even if this vehi-
cle is equipped with Volvo’s advanced AWD
or DSTC system, 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.
Certain models are equipped with "all-season"
tires, which provide a somewhat higher degreeof road holding on slippery surfaces than tires
without 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 TiresRemember that tires are per-
ishable goods. As of 2000, the
manufacturing week and year
(Department of Transporta-
tion (DOT) stamp) will be indi-
cated with 4 digits (e.g. 1502
means that the tire illustrated
was manufactured during week 15 of 2002).
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.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. For the tire
pressure tables, see page 181.
•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.

Loading the vehicle
Before loading your vehicle, familiarize yourself
with the following terms for determining your
vehicle's weight ratings, with or without a
trailer, from the vehicle's Federal/Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label, and the vehicle's tire informa-
tion placard:
Curb weightThe weight of the vehicle including a full tank
of fuel and all standard equipment. It does not
include passengers, cargo, or optional equip-
ment.
Capacity weightAll weight added to the curb weight, including
cargo and optional equipment. When towing,
trailer hitch tongue load is also part of cargo
weight.
NOTE
For trailer towing information, please refer to
the section "Towing a trailer", see
page 162.
Permissible axle weightThe maximum allowable weight that can be
carried by a single axle (front or rear). These
numbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/
CMVSS) label. The total load on each axle must
never exceed its maximum permissible weight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-
gers.
NOTE
•The location of the various labels in your
vehicle can be found on page 268.
•A table listing important weight limits for
your vehicle can be found on page
271.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined
weight of occupants and cargo should
never exceed XXX pounds" on your vehi-
cle's placard.
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3. Subtract the combined weight of the driver
and passengers from XXX kilograms or
XXX pounds.
4. The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400 lbs. and there will be five
150 lbs. passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400–750 (5×150)
= 650 lbs.)
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle.
That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual1 to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.

07 Wheels and tires
Temporary spare

190
Temporary spare
The spare tire in your vehicle1 is called a "Tem-
porary 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.
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.
1Not on models equipped with the Tire sealing system.

07 Wheels and tires
Tire Pressure Monitoring System (TPMS)
07

199 Introduction
The tire pressure monitoring system uses sen-
sors mounted in the tire valves to check infla-
tion pressure levels. When the vehicle is mov-
ing 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 fol-
lowing 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 one of the following mes-
sages in the text window:
LOW TIRE PRESS.
CHECK TIRES or VERY LOW TIRE
PRESSURE.
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 pres-
sure 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 pres-
sure. 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 driv-er's responsibility to maintain correct tire pres-
sure, 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 mal-
function 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.

08 Car care
Washing and cleaning the car
08
204* Option/accessory, for more information, see Introduction.
Washing the car
The following points should be kept in mind
when washing and cleaning the car:
•The car should be washed at regular inter-
vals since dirt, dust, insects and tar spots
adhere to the paint and may cause dam-
age. To help prevent corrosion, it is partic-
ularly important to wash the car frequently
in the wintertime when salt has been used
on the roads.
•Avoid washing your car in direct sunlight.
Doing so may cause detergents and wax
to dry out and become abrasive. To avoid
scratching, use lukewarm water to soften
the dirt before you wash with a soft
sponge, and plenty of sudsy water.
•Bird droppings: Remove from paintwork
as soon as possible. Otherwise the finish
may be permanently damaged.
•A detergent can be used to facilitate the
softening of dirt and oil.
•Dry the car with a clean chamois and
remember to clean the drain holes in the
doors and rocker panels.
•Tar spots can be removed with tar remover
after the car has been washed.
•A stiff-bristle brush and lukewarm soapy
water can be used to clean the wiper
blades. Frequent cleaning of the wind-
shield and wiper blades improves visibilityconsiderably and also helps prolong the
service life of the wiper blades.
•Wash off the dirt from the underside (wheel
housings, fenders, etc).
•In areas of high industrial fallout, more fre-
quent washing is recommended.
NOTE
When washing the car, remember to remove
dirt from the drain holes in the doors and
sills.
Exterior componentsVolvo recommends the use of special cleaning
products, available at your Volvo retailer, for
cleaning colored plastic, rubber, or ornamental
components such as chromed strips on the
exterior of your vehicle. The instructions for
using these products should be followed care-
fully. Solvents or stain removers should not be
used.
CAUTION
•Avoid waxing or polishing plastic or rub-
ber components
•Polishing chromed strips can wear
away or damage the surface
•Polishes containing abrasive sub-
stances should not be used
CAUTION
•During high pressure washing, the
spray mouthpiece must never be closer
to the vehicle than 13" (30 cm). Do not
spray into the locks.
•Dirt, snow, etc., on the headlights can
reduce lighting capacity considerably.
Clean the headlights regularly, for
example when refueling.
Special moonroof cautions:
•Always close the moonroof* and sun
shade before washing your vehicle.
•Never use wax on the rubber seals
around the moonroof.
•Never use abrasive cleaning agents on
the moonroof.
•

09 Maintenance and servicing
Maintaining your car 09
214
Owner maintenance
Periodic maintenance requirements and inter-
vals are described in your vehicle's Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.
Each time the car is refueled:
•Check the engine oil level.
•Clean the windshield, windshield wipers,
headlights, and taillights.
Monthly:
•Check cold tire pressure in all tires. Inspect
the tires for wear.
•Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
•Clean interior glass surfaces with a glass
cleaner and soft paper towels.
•Wipe driver information displays with a soft
cloth.
•Visually inspect battery terminals for cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult a trained
and qualified Volvo service technician for
additional information.
As needed:
•Wash the car, including the undercarriage,
to reduce wear that can be caused by a
buildup of dirt, and corrosion that can be
caused by salt residues.
•Clean leaves and twigs from air intake
vents at the base of the windshield, and
from other places where they may collect.
NOTE
Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvotechinfo.com.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the
two jack attachments points should be used.
They are specially reinforced to bear the weight
of the vehicle. A garage jack can also be placed
under the front of the engine support frame.
Take care not to damage the splash guard
under the engine. Ensure that the jack is posi-
tioned so that the vehicle cannot slide off it.
Always use axle stands or similar structures.
If a two-post hoist is used to lift the vehicle, the
front and rear lift arm pads should be centered
under the reinforced lift plates on the inboard
edge of the sill rail (see illustration).
Emission inspection readiness
What is an Onboard Diagnostic System
(OBD II)?
OBD II is part of your vehicle's computerized
engine management system. It stores diagnos-
tic information about your vehicle's emission
controls. It can light the Check Engine light
(MIL) if it detects an emission control "fault." A
"fault" is a component or system that is not
performing within an expected range. A fault
may be permanent or temporary. OBD II will
store a message about any fault.
