Roof loads
Using load carriers
Load carriers are available as Volvo accessories. Observe the following points when in use:
To avoid damaging your vehicle and to achieve maximum safety when driving, we recommend using the load
carriers that Volvo has developed especially for your vehicle.
Volvo-approved removable roof racks are designed to carry the maximum allowable roof load for this vehicle: 220
lbs (100 kg). For non-Volvo roof racks, check the manufacturer's weight limits for the rack.
Never exceed the rack manufacturer's weigh limits and never exceed the maximum rated roof load of 220 lbs (100
kg).
Avoid single-point loads. Distribute loads evenly.
Place heavier cargo at the bottom of the load.
Secure the cargo correctly with appropriate tie-down equipment.
Check periodically that the load carriers and load are properly secured.
Remember that the vehicle's center of gravity and handling change when you carry a load on the roof.
The vehicle's wind resistance and fuel consumption will increase with the size of the load.
Drive smoothly. Avoid rapid starts, fast cornering and hard braking.

201 05 During your trip
Towing a trailer
Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
NOTE
See page 270
for the maximum trailer and tongue weights recommended by Volvo.
Observe the legal requirements of the state/province in which the vehicles are
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 tire inflation tables on pages 240 and 241.
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 mph (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 text window.
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.
Volvo recommends the use of synthetic engine oil when towing a trailer over long distances or in mountainous
areas.
WARNING
Bumper-attached trailer hitches must not be used on Volvos, nor should safety chains be attached to the bumper.
Trailer hitches attaching to the vehicle rear axle must not be used.
Never connect a trailer's hydraulic brake system directly to the vehicle brake system, nor a trailer's lighting system
directly to the vehicle lighting system. Consult your nearest authorized Volvo retailer for correct installation.
When towing a trailer, the trailer's safety wire must be correctly fastened to the hole or hook provided in the
trailer hitch on the vehicle. The safety wire should never be fastened to or wound around the drawbar ball.
202 05 During your trip
Towing a trailer
NOTE

When parking the vehicle with a trailer on a hill, apply the parking brake before putting the gear selector in P.
Always follow the trailer manufacturer's recommendations for wheel chocking.
When starting on a hill, put the gear selector in D before releasing the parking brake. See also page 117 for more
detailed information about starting off on a hill while towing a trailer.
If you use the manual (Geartronic) shift positions while towing a trailer, make sure the gear you select does not
put too much strain on the engine (using too high a gear).
The drawbar assembly/trailer hitch may be rated for trailers heavier than the vehicle is designed to tow. Please
adhere to Volvo's recommended trailer weights.
Avoid driving with a trailer on inclines of more than 15 %.
Trailer cable
An adapter is required if the vehicle's trailer hitch has a 13-pin connector and the trailer has 7 pins. Use an adapter
cable approved by Volvo. Make sure the cable does not drag on the ground.

Please 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, etc.
If the vehicle's battery is dead, do not attempt to start the vehicle by pushing or pulling it as this will damage the
three-way catalytic converter(s). The engine must be jump started using an auxiliary battery (see page 109
).
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.
205 05 During your trip
Emergency towing
Towing vehicles with front wheel drive/All Wheel Drive
Volvo recommends the use of flat bed equipment.
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 page 204
.
CAUTION
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use sling -type equipment at the rear or apply lifting equipment inside the rear

Introduction
Volvo advises you to follow the maintenance program outlined in the Warranty and Service Records Information
booklet. This maintenance program contains inspections and services necessary for the proper function of your vehicle.
The maintenance services contain several checks that require special tools and training, and therefore must be
performed by a qualified technician. To keep your Volvo in top condition, specify time-tested and proven Genuine
Volvo Parts and Accessories.

Each time the car is refueled:
Check the engine oil level.
Clean the windshield, windshield wipers, headlights, and tail lights.
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 corrosion. Corrosion may indicate a loose terminal connector, or a battery near
the end of its useful service life. Consult your Volvo retailer 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.

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.

WARNING
The ignition should always be completely switched off before performing any operations in the engine compartment.
The distributor ignition system operates at very high voltages. Special safety precautions must be followed to prevent
injury. Always turn the ignition off when:
Replacing distributor ignition components e.g. plugs, coil, etc.
Do not touch any part of the distributor ignition system while the engine is running. This may result in unintended
movements and body injury.
212 06 Maintenance and specifications
Engine oil
Checking the engine oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to
the first scheduled maintenance service.
See page 272 for oil specifications.
Refer to the Warranty and Service Records Information booklet for information on the oil change intervals.
Volvo recommends Castrol.
CAUTION
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Oil that is lower than the specified quality can damage the engine.

Volvo does not recommend the use of oil additives.
Always add oil of the same type and viscosity as already used.
Never fill oil above the MAX mark. This could cause an increase in oil consumption.
Checking and adding oil
NOTE
Before checking the oil:
The car should be parked on a level surface when the oil is checked.
If the engine is warm , wait for at least 10-15 minutes after the engine has been switched off before checking the
oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level. The level must be between the MIN and MAX marks.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately 0.5 US quarts (0.5 liters) of oil.
4. Recheck the level and add more oil if necessary until the level is near the MAX mark.
213 06 Maintenance and specifications
Engine oil
WARNING

Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge. Please consult your Volvo retailer.
214 06 Maintenance and specifications
Fluids
Coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified
Volvo service technician.
See page 275
for information on cooling system capacities.
CAUTION
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly.
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.
If it is necessary to top off the coolant when the engine is warm, unscrew the expansion tank cap slowly so that
the overpressure dissipates.
