Screw the towing eyelet in place first by hand and then using the tire iron until it is securely in place (3).
After the vehicle has been towed, the eyelet should be unscrewed and returned to its storage place. Press the plastic
cover in bumper back into position.
WARNING!
Volvo does not recommend towing a disabled vehicle behind another vehicle. Significant difficulty in steering and
braking, combined with unfavorable weather, traffic, and road conditions may make it impossible to maintain
vehicle control.
Towing a vehicle with all four wheels on the ground
Apply the parking brake.
Insert the key into the ignition to unlock the steering wheel. The steering wheel must be unlocked. With the engine
off and the vehicle at a standstill, great effort will be required to turn the steering wheel.
WARNING!
Towing a vehicle with a locked steering wheel will make the vehicle impossible to steer.
Turn the ignition key to position II.
Place the gear selector in neutral. For vehicles with automatic transmissions, follow instruction on page 110,
"Shiftlock override" to allow the gear selector to be moved from the Park position.
Keep firm pressure on the brake pedal while releasing the parking brake.
When towing has been completed, return the gear selector to Park (automatic) or Reverse (manual) and apply the
parking brake.
pg. 118 Starting and driving
Towing
The following points should also be observed:
Never exceed 50 mph (80 km/h). Never exceed local towing speed limits and heed all local towing restrictions.
Never tow farther than 50 miles (80 km).
Keep the tow rope taut at all times while the vehicle is in motion.
The disabled vehicle should be towed in the forward direction only.
WARNING!
Never allow a vehicle to be towed without a driver behind the wheel of the disabled vehicle.
Never remove the key from the ignition while the vehicle is moving. The steering wheel could lock, making it
impossible to steer the vehicle.
When the engine is not running, steering resistance and the effort needed to apply the brakes will be great.
Never attempt to tow a vehicle with a dead battery at night.
CAUTION!
Check with state and local authorities before attempting this type of towing, as vehicles being towed are subject to
regulations regarding maximum towing speed, length and type of towing device, lighting, marker flags, etc.

Never attempt to push- or tow-start a vehicle with a dead battery. This would inject unburned fuel into the three-
way catalytic converter(s), causing overheating, backfiring, and damage. See page 119 for instructions on jump
starting the vehicle.
Having the car towed
Volvo recommends the use of flat bed equipment for towing vehicles with front wheel drive. If wheel lift equipment
must be used, please use extreme caution to help avoid damage to the vehicle.
In this case, the vehicle should be towed with the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle with the front wheels on the ground, please refer to the towing
information on the previous page.
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use slingtype equipment at the rear or apply lifting equipment inside the rear wheels;
serious damage to the rear axle may result.
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the flat
bed. Consult the tow truck operator.
WARNING!
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.
pg. 119 Starting and driving
Jump starting
Follow these instructions to jump start your vehicle's dead battery or to jump start another vehicle's dead battery using
your vehicle. If the 12-volt auxiliary battery to be used is in another vehicle, check that the vehicles are not touching to
prevent premature completion of a circuit. Be sure to follow jump starting instructions provided for the other vehicle.
To jump start your vehicle:
Switch off the ignition.
First connect the auxiliary battery positive (+) terminal (1) to the positive (+) terminal in your vehicle's battery (2),
marked with a "+" sign.
Connect the auxiliary battery's negative (-) terminal (3) to the ground point in your vehicle's engine compartment
near the driver's side spring strut (4).
Start the engine in the assisting vehicle, then start the engine in the vehicle with dead battery.

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)!

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. Failure 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
possible 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 regulations restricting the use of studded winter tires before installing such
tires.

Wheel nuts
Wheel nuts
There are two different types of wheel nut, depending on whether the wheels are steel or aluminum.
Steel rims - low nut
Steel 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 aluminium wheels. This could cause the wheel to come loose.
Aluminum wheels - high nut
Only the high type of nut can be used for aluminum wheels. This is considerably different from other types of nut
because it has a rotating conical thrust washer.
NOTE: This nut can also be used on steel wheels.
Lockable wheel nut
If 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.

the car. The use of different size wheels can seriously damage your car's transmission.
Location of the optional spare wheel and tools
The spare wheel is packed in a storage bag and is located under the panel in the floor of the trunk. On cars with a
spare wheel, the jack and lug wrench are secured in a foam plastic block placed in the center of the wheel. The
retaining straps securing the spare wheel is attached to two eyelets in the floor of the spare wheel's storage
compartment.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary 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 50 mph (80 km/h). Do not drive farther than 50 miles (80 km) on
a temporary spare tire.
Accessing the spare wheel:
Open the hatch in the floor of the trunk.
Release the retaining straps and lift out the spare wheel in its storage bag.
Open the zipper on the storage bag and lift out the spare wheel.
The wheel that was replaced by the temporary spare tire can then be placed in the storage bag.

Changing a wheel

Before raising the car:
Engage the parking brake.
Put the gear selector in (P)ark or in reverse if the car is equipped with a manual transmission.
Block the wheels that are on the ground with wooden blocks or large stones.
Remove the wheel cap (where applicable) using the lug wrench.
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.

Your vehicle is 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 tire sealing kit is stowed behind the ski hatch in the center of the rear seat backrest.
The jack, and lug wrench are secured in a foam plastic block located under the floor panel in the trunk.
The system consists of an air compressor, an integrated 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.
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 replaced as soon as possible.
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.

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.

Battery
Battery maintenance
Driving habits and conditions, climate, the number of starts, etc., all affect the service life and function of the battery.
In order for your battery to perform satisfactorily, keep the following in mind:
Check the fluid level in each cell in the battery every 24 months or every 15,0001 miles (24,000 km), whichever is
sooner. The fluid should be at the level shown in the illustration above (A). Do not overfill.
Use a screw driver to open the caps and a flashlight to inspect the level.
If necessary, add distilled water. The level should never be above the indicator (A).
The fluid level should be checked if the battery has been recharged.
After inspection, be sure the cap over each battery cell is securely in place.
Check that the battery cables are correctly connected and properly tightened.
Never disconnect the battery when the engine is running, or when the key is in the ignition. This could damage the
vehicle's electrical system.
