warning VOLVO C70 2008 Manual Online

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 tires, 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.
Snow tires, studded tires
Tires for winter use:
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.
ProCarManuals.com

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.

Temporary spare
Temporary spare (option)
The spare tire in your car is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar) should be maintained irrespective of which position on
the car the temporary spare tire is used on.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
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.
CAUTION
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
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.

Tire sealing system
Introduction
Certain models are equipped with a tire sealing system that enables you to temporarily seal a hole in the tread surface
and reinflate a flat tire, or to adjust a tire's inflation pressure.
The system consists of an air compressor, a 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.
The 12-volt sockets are located in the front tunnel console and in the trunk (option). See pages 66
and 108.
Accessing the tire sealing system
The tire sealing system is stowed in the compartment in the rear side of the ski hatch in the center of the rear seat
backrest. See page 109
for information on opening this hatch
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.

Tire sealing system-temporarily repairing a flat tire
ProCarManuals.com

Temporarily repairing a flat tire is done in two stages:
Stage 1: 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.
NOTE
Do not remove any foreign objects (nails, etc.) from the tire before using the sealing system.
NOTE
Stage 2: The tire's inflation pressure is checked and adjusted if necessary.
WARNING
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system away from children.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Stage 1: Sealing the hole
1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it to the steering wheel hub where it will be clearly visible to the driver.
3. Ensure that the on/off switch is in position 0 (the 0 side of the switch should be pressed down).
4. Put on the gloves included in the tire sealing system.
5. Unscrew the orange cover over the bottle holder and unscrew the cap on the bottle of sealing compound.
NOTE
Do not break the seal on the bottle. This occurs automatically when the bottle is screwed into the holder.
6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep it securely in place and help prevent sealing compound leakage. Once in
place, the bottle cannot be unscrewed. This must be done by a Volvo retailer.
7. Remove the valve cap from the tire's inflation valve and screw the tire sealing system's hose connector onto the
valve as tightly as possible by hand.
8. Connect the electrical wire to the nearest 12-volt socket in the vehicle.

9. Start the vehicle's engine.
WARNING
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, or outdoors, before using the system.
10. Start the tire sealing system's compressor by pressing the on/off switch to position I .
WARNING
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.
NOTE
The air pressure gauge 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 30
seconds.
11. Within seven minutes, inflate the tire to between 22-44 psi (1.8-3.0 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoid overheating.
WARNING
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.
12. Switch off the compressor and disconnect the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
14. Immediately drive the vehicle for approximately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to
distribute the sealing compound in the tire.
NOTE
Safely stow the tire sealing system in a convenient place as it will soon be used again to check the tire's inflation
pressure.
After use, the empty bottle of sealing compound cannot be removed from the bottle holder. Consult a Volvo
retailer to have the bottle removed and properly disposed of.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the
