VOLVO C70 2006 Owners Manual

grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of cornering (turning)
traction.
WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of
cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a minimum level of performance that all
passenger vehicle tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.
WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and tire
failure.

Snow chains, snow tire, studded tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
If accessory, aftermarket or "custom" tires and wheels are installed and are of a size different than the original tires
and wheels, chains in some cases CANNOT be used. Sufficient clearances between chains and brakes, suspension and
body components must be maintained.
Some strap -on type chains will interfere with brake components and therefore CANNOT be used. Consult your
Volvo retailer for additional snow chain information.
CAUTION!
Check local regulations regarding the use of snow chains before installing.
Always follow the chain manufacturer's installation instructions carefully. Install chains as tightly as possible and
retighten periodically.
Never exceed the chain manufacturer's specified maximum speed limit. (Under no circumstances should you
exceed 31 mph
(50 km/h).
Avoid bumps, holes or sharp turns when driving with snow chains.
The handling of the vehicle can be adversely affected when driving with chains. Avoid fast or sharp turns as well
as locked wheel braking.

Tires for winter use:
ProCarManuals.com

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.

Tire rotation
Summer and winter tires
When switching between summer and winter tires, mark the tires to indicate where they were mounted on the car,
e.g. LF = left front, RR = right rear
Tires with tread designed to roll in only one direction are marked with an arrow on the sidewall.
Incorrectly mounted tires impair the car's braking properties and ability to force aside rain, snow and slush.
The tires with the most tread should always be at the rear (to reduce the risk of skidding).
Contact a Volvo workshop if you are unsure about the tread depth.

Changing a wheel
Temporary Spare (option)
The spare tire is called a "Temporary 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.
CAUTION!
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
ProCarManuals.com

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.

Tire sealing system
ProCarManuals.com

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.

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.

), the use of the sealing
compound may lead to incorrect tire pressure readings or in rare cases, damage to the tire pressure sensor. Use the
tire sealing system to check and adjust the damaged tire's pressure.
After use, return the tire sealing system to its storage compartment behind the ski hatch in the center of the rear seat
backrest.
WARNING!
If you interrupt your trip for more than one hour, check the inflation pressure in the damaged tire again before
continuing. See the section "Stage 2: Checking inflation pressure" on page 143
.
Replacing the sealing compound container
The sealing compound container must be replaced if:
the tire sealing system has been used to repair a tire the container's expiration date has passed (see the date on decal
1).
After use, the container (6), its retaining bracket (9), and the hose (10) must be replaced. Please consult your Volvo
retailer for replacement parts.
