Towing a trailer
General information
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
Maximum trailer weights recommended by Volvo are:
Trailers without brakes : 1,540 lbs (700 kg).
Trailers with brakes: 2,000 lbs (900 kg) Observe the legal requirements of the state/province in which the vehicles
are registered.
The maximum recommended hitch tongue load is 165 lbs (75 kg).
All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
Trailer towing does not normally present any particular problems, but take into consideration:
Increase tire pressure to recommended full. See the chapter "Wheels and tires."
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 m.p.h. (80 km/h).
Engine and transmission are subject to increased loads. Therefore, engine coolant temperature should be closely
watched when driving in hot climates or hilly terrain. Use a lower gear and turn off the air conditioner if the
temperature gauge needle enters the red range.
If the automatic transmission begins to overheat, a message will be displayed in the information display.
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, and economy.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop (check and observe
state/local regulations).
Do not connect the trailer's brake system directly to the vehicle's brake system.
More frequent vehicle maintenance is required.
Remove the ball and drawbar assembly when the hitch is not being used.
ProCarManuals.com

Slide the ball holder into the hitch assembly.
Align the hole in the ball holder with the one in the hitch assembly.
Slide the locking bolt through the hitch assembly/ball holder.
Insert the cotter pin in the hole at the end of the locking bolt.
Removing the ball holder
Remove the cotter pin from the locking bolt and slide the locking bolt out of the ball holder/hitch assembly.
Pull the ball holder out of the hitch assembly.
NOTE: A cover for the hitch assembly is also included in the kit.
pg. 123 Starting and driving
Transporting loads
Loading the car Your vehicle's load-carrying capacity is affected by factors such as:
the number of passengers
tire inflation
the amount of optional or accessory equipment 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 the cargo 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.
WARNING!
Remember that an object weighing 44 lbs (20 kg) produces a force of 2,200 lbs (1,000 kg) in a head-on collision at
30 m.p.h. (50 km/h)!

General information
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.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces.
Certain models are equipped with "all-season" tires, which provide a somewhat higher degree of 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
characteristics.
Storing wheels and tires
When 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.
ProCarManuals.com

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.
Tread wear indicator
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 on page 130
.
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.
pg. 127 Wheels and tires
General information
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, which can affect their reliability and roadholding
characteristics. Therefore, all tires older than 6 years (including the spare tire and winter tires) should be inspected by a
qualified technician, regardless of appearance or mileage. Heat caused by hot climates or frequent high loading
conditions can accelerate the aging process.
ProCarManuals.com

A tire's age can be determined by the DOT stamp on the sidewall (see the illustration above).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy:
Maintain correct tire pressure. See the tire pressure table on page 130.
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.
pg. 128 Wheels and tires
Tire inflation
Tire inflation
Check tire inflation pressure regularly.
A table listing the recommended inflation pressure for your vehicle can be found on page 130
. Tire inflation pressure
placards are 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), or on the inside of the fuel filler door on Canadian models. These placards indicate the
designation of the factory-mounted tires on your vehicle, as well as load limits and inflation pressure.
ProCarManuals.com

NOTE: The placards shown indicate inflation pressure for the tires installed on the car at the factory only.
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.
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 certification 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 surrounding (ambient) air.
This temperature is normally reached after the car has been parked for at least 3 hours.
pg. 129 Wheels and tires
Tire inflation
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
pressure 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 pressures 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:
Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
Add air to reach the recommended air pressure
Replace the valve cap.
Repeat this procedure for each tire, including the spare.
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.
Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
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 table on page 130 or
see the inflation pressure placard.

Tire designations
ProCarManuals.com

Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewall edge. The larger the number, the wider the
tire.
2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H : The tire's speed rating, or the maximum speed at which the tire is designed to be driven for extended periods of
time, carrying a permissible load for the vehicle, and with correct inflation pressure. For example, H indicates a speed
rating of 130 mph (210 km/h).
NOTE: This information may not appear on the tire because it is not required by law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and indicates that the tire meets
all federal standards. The next two numbers or letters are the plant code where it was manufactured, the next two are
the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers
317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of
2001. The numbers in between are marketing codes used at the manufacturer's discretion. This information helps a tire
manufacturer identify a tire for safety recall purposes.
9. Tire Ply Composition and Material Used : Indicates the number of plies indicates or the number of layers of
rubber-coated fabric in the tire tread and sidewall. Tire manufacturers also must indicate the ply materials in the tire
and the sidewall, which include steel, nylon, polyester, and others.
10. Maximum Load : Indicates the maximum load in pounds and kilograms that can be carried by the tire. Refer to the
vehicle's tire information placard or the safety certification label, located on the B-Pillar or the driver's door or on the
inside of the fuel filler door on Canadian models, for the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperature grades : See page 134
for more information.
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This
limit is set by the tire manufacturer.
