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)!

Temporarily repairing a flat tire
Before using the tire sealing system, observe the following:
WARNING!
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system kit away from children.
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be
sure the vehicle is parked in a well ventilated place before using the system.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Do not remove any foreign objects (nails, etc.) from the tire.
Temporarily repairing a flat tire is done in two stages.
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.
In the second stage, the tire's inflation pressure is checked and adjusted if necessary.
Stage 1: Sealing the hole
Peel off the speed limit sticker (1) and affix it to the steering wheel hub where it will be clearly visible to the driver.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Pull out the electrical wire (5) and hose (4) from the side compartment (3).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
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.
Start the vehicle's engine.
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 pressure to approximately 88 psi (6 bar) while
the sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately
one minute.
pg. 143 Wheels and tires
Tire sealing system
WARNING!
ProCarManuals.com

Contact with the sealing compound may cause skin irritation. If contact occurs, wash the affected area immediately
with soap and water.
Never stand next to the tire being inflated when the compressor is in operation. If cracks, bubbles, etc. form on the
tire, switch off the compressor immediately. If there is visible damage to the sidewall or the rim, the tire cannot be
repaired. The vehicle should not be driven if this occurs. Contact a towing service or Volvo On Call Roadside
Assistance if applicable.
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).
CAUTION!
If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn off the compressor. In this
case, the hole is too large to be sealed and the vehicle should not be driven.
Disconnect the electrical wire from the 12-volt socket.
Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
Fold down the orange section of the tire sealing system to its original (horizontal) position and press the safety catch
into place.
Safely stow the tire sealing system kit in a convenient place as it will soon be used again to check the tire's inflation
pressure.
Immediately drive the vehicle for approximately 2 miles (3 km) to distribute the sealing compound in the tire.
WARNING!
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the car
in a safe place. Recheck the tire for bumps, cracks, or other visible damage, and recheck its inflation pressure. If the
pressure is below 16 psi (1.3 bar), do not continue driving. Have the vehicle towed to a workshop or Volvo retailer.
Stage 2: Checking inflation pressure
Park the car in a safe place.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Start the vehicle's engine.
Check the tire's inflation pressure on the gauge (9).
NOTE: In dark conditions, switching on the tire sealing system's compressor will illuminate the pressure gauge.
Inflate the tire to the correct pressure as indicated in the tire inflation tables on page 116. If the tire needs to be
inflated, start the tire sealing system's compressor. If necessary, release air from the tire by pressing the vent button (8).
Turn off the compressor (press switch 2 to the 0 position) when the correct inflation pressure has been reached.

Washing and cleaning the car
Washing the car
The following points should be kept in mind when washing and cleaning the car:
The car should be washed at regular intervals since dirt, dust, insects and tar spots adhere to the paint and may cause
damage. To help prevent corrosion, it is particularly important to wash the car frequently in the wintertime.
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.
A water-soluble grease solvent may be used in cases of sticky dirt. However, use a wash place equipped with a
drainage separator.
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 kerosene or 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 improves
visibility considerably.
Wash off the dirt from the underside (wheel housings, fenders, etc).
In areas of high industrial fallout, more frequent washing is recommended.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
Exterior plastic components
Cleaning exterior plastic components should be done with a cleaning agent specially designed for this purpose.
Solvents or stain removers should not be used. Consult your Volvo retailer.
NOTE: When washing the car, remember to remove dirt from the drain holes in the doors and sills.
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.
When washing or steam cleaning the engine, avoid spraying water or steam directly on the electrical components or
toward the rear side of the engine.
ProCarManuals.com

Automatic washing - simple and quick
We do NOT recommend washing your car in an automatic wash during the first six months (because the paint will
not have hardened sufficiently).
An automatic wash is a simple and quick way to clean your car, but it is worth remembering that it may not be as
thorough as when you yourself go over the car with sponge and water. Keeping the underbody clean is most important,
especially in the winter. Some automatic washers do not have facilities for washing the underbody.
pg. 149 Vehicle care
Washing and cleaning the car
CAUTION!
Before driving into an automatic carwash, turn off the optional rain sensor to avoid damaging the windshield wipers.
Make sure that side view mirrors, auxiliary lamps, etc, are secure, and that any antenna(s) are retracted or removed.
Otherwise there is risk of the machine dislodging them.
WARNING!
When the car is driven immediately after being washed, apply the brakes several times in order to remove any
moisture from the brake linings.
Engine cleaning agents should not be used when the engine is warm. This constitutes a fire risk.
Polishing and Waxing
Normally, polishing is not required during the first year after delivery, however, waxing may be beneficial.
Before applying polish or wax the vehicle must be washed and dried. Tar spots can be removed with kerosene or tar
remover. Difficult spots may require a fine rubbing compound.
After polishing use liquid or paste wax.
Several commercially available products contain both polish and wax.
Waxing alone does not substitute for polishing a dull surface.
A wide range of polymer-based waxes can be purchased today. These waxes are easy to use and produce a long-
lasting, high-gloss finish that protects the bodywork against oxidation, road dirt and fading.
Do not polish or wax your vehicle in direct sunlight (the surface of the vehicle should not be warmer than 113° F
(45° C).
CAUTION!
Volvo does not recommend the use of long-life or durable paint protection coatings, some of which may claim to
prevent pitting, fading, oxidation, etc. These coatings have not been tested by Volvo for compatibility with your
vehicle's clear coat. Some of them may cause the clear coat to soften, crack, or cloud. Damage caused by application
of paint protection coatings may not be covered under your vehicle's paint warranty.

Maintaining your car
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 diagnostic 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.
How do states use OBD II for emission inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can then read "faults." In some
states, this type of inspection has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons.
If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
If your vehicle's Check Engine light was lit, but went out without any action on your part, OBD II will still have a
recorded fault. Your vehicle may pass or fail, depending on the inspection practices in your area.
If you had recent service that required disconnecting the battery, OBD II diagnostic information may be incomplete
and "not ready" for inspection. A vehicle that is not ready may fail inspection.
How can I prepare for my next OBD II emission inspection?
If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if
necessary, serviced by a qualified Volvo technician.
If you recently had service for a lit Check Engine light, or if you had service that required disconnecting the battery,
a period of driving is necessary to bring the OBD II system to "ready" for inspection. A half-hour trip of mixed stop-
and -go/ highway driving is typically needed to allow OBD II to reach readiness. Your Volvo retailer can provide you
with more information on planning a trip.
Maintain your vehicle in accordance with your vehicle's maintenance schedule.
