tires VOLVO C70 CONVERTIBLE 2007 Owner´s Manual

2007 Volvo C70
The traction 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 c\
ontrolled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degener\
ate 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 passe\
nger vehicle tires must meet
under the Federal Motor Safety Standard No. 109. Grades B and A represen\
t 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 pr\
operly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading, either separatel\
y 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:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l 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. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
Consult your Volvo retailer for additional snow chain information.

CAUTION
l Check local regulations regarding the use of snow chains before installi\
ng.
l Always follow the chain manufacturer's installation instructions careful\
ly. Install chains as tightly as
possible and retighten periodically.
l Never exceed the chain manufacturer's specified maximum speed limit. (U\
nder no circumstances
should you exceed 31 mph (50 km/h).
l Avoid bumps, holes or sharp turns when driving with snow chains.
l 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:
l Owners who live in or regularly commute through areas with sustained per\
iods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help ret\
ain the highest degree of traction.
l It is important to install winter tires on all four wheels to help retai\
n traction during cornering, braking,
and accelerating. Failure to do so could reduce traction to an unsafe le\
vel or adversely affect handling.
l Do not mix tires of different design as this could also negatively affec\
t overall tire road grip.
l Winter tires wear more quickly on dry roads in warm weather. They should\
be removed when the
winter driving season has ended.
l Studded tires should be run-in 300-600 miles (500-1000 km) during whic\
h 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 st\
udded winter tires before installing
such tires.

There are two different types of wheel nut, depending on whether the whe\
els are steel or aluminum.
Steel rims - low nut
Steel rims are normally secured using the low type of nut, although stee\
l rims may also use the high type.
WARNING
Never use the short type of nut for aluminium wheels. This could cause t\
he wheel to come
loose.
Aluminum wheels - high nut
Only the high type of nut can be used for aluminum wheels. This is consi\
derably 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 wh\
eel covers, the lockable wheel
nut must be fitted to the stud nearest the air valve. The wheel cover ca\
nnot otherwise be installed on the
wheel.

Tire rotation
Summer and winter tires
l When switching between summer and winter tires, mark the tires to indica\
te where they were mounted
on the car, e.g. LF = left front, RR = right rear
l Tires with tread designed to roll in only one direction are marked with \
an arrow on the sidewall.
l Incorrectly mounted tires impair the car's braking properties and abilit\
y to force aside rain, snow and
slush.
l The tires with the most tread should always be at the rear (to reduce t\
he risk of skidding).
Contact a Volvo workshop if you are unsure about the tread depth.
Tire rotation
Your vehicle has no recommended tire rotation. The following information\
is intended to help you
understand why.
Tread set
As a tire ages and the rubber cures, front and rear tires set at differe\
nt angles. Therefore, if tires are
rotated, the tread will eventually set at an angle that is a compromise.\
Even if ride, handling, and road
noise may still seem acceptable, they may not be optimal. Further, tires\
that are rotated, but not on a
regular basis, may actually cause more tire noise, faster tire wear, and\
unpleasant changes in steering feel
and vehicle handling.
A tire that can fully adapt to its position will provide better steering\
feel, lower tire noise, and better fuel
economy.
Braking stability performance
Your vehicle is driven mainly by the front tires, which will wear faster\
. This can be beneficial. Having

more tread on the rear tires will help reduce oversteer. Oversteer is wh\
en a vehicle wants to keep turning
because of momentum and dynamic forces on its suspension.
Suspension wear diagnostics
Every suspension needs periodic inspection and maintenance. A tire's wea\
r pattern can be an aid in
detecting a suspension problem. Each tire, if left in place, tells a sto\
ry about the suspension. Tire rotation,
on the other hand, could make suspension wear harder to detect. Early de\
tection is very important,
because suspension problems can make tire wear worse.
If you do rotate your tires...
Please follow the tire manufacturer's recommendations, as outlined in th\
e tire manufacturers tire warranty
pamphlet.

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 you\
r Volvo retailer.
Location of the optional spare wheel and tools
The spare wheel is packed in a storage bag and is located under the pane\
l in the floor of the trunk.

2007 Volvo C70
On cars with a spare wheel, the jack and lug wrench are secured in a foa\
m 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 d\
amage 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 othe\
r than as a temporary
replacement for a punctured tire. It must be replaced as soon as possibl\
e by a standard tire. Road holding
and handling may be affected with the "Temporary Spare" in use. Do not e\
xceed 50 mph (80 km/h). Do
not drive farther than 50 miles (80 km) on a temporary spare tire.

Tire sealing system
Tire sealing system
Your vehicle is 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 press\
ure.
l The tire sealing kit is stowed behind the ski hatch in the center of the\
rear seat backrest.

2007 Volvo C70
The system consists of an air compressor, an integrated container for th\
e 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 tre\
ad area, not the
sidewall.
l Tires with large holes or tears cannot be repaired with the tire sealing\
system.
WARNING
l After using the tire sealing system, the vehicle should not be driven fa\
rther than approximately 120
miles (200 km). Have the tire replaced as soon as possible.
l The vehicle should not be driven faster than 50 mph (80 km/h) while us\
ing a tire that has been
temporarily repaired with the tire sealing system.
l After using the tire sealing system, drive carefully and avoid abrupt st\
eering maneuvers and sudden
stops.
l A tire that has been temporarily inflated with the tire sealing kit cann\
ot be repaired and re-used. It
must be replaced.

WARNING
l Never leave the tire sealing system unattended when it is operating.
l Keep the tire sealing system kit away from children.
l The vehicle's engine should be running when the tire sealing system is u\
sed to avoid battery drain.
Therefore, be sure the vehicle is parked in a well ventilated place befo\
re using the system.
l Be sure the vehicle is parked safely off the road and away from moving t\
raffic.
l Apply the parking brake.
l Do not remove any foreign objects (nails, etc.) from the tire.
172 07 Wheels and tires
Tire sealing system
Temporarily repairing a flat tire is done in two stages
l 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.
l In the second stage, the tire's inflation pressure is checked and adjust\
ed if necessary.
Stage 1 - Sealing the hole
Peel off the speed limit sticker (1) and affix it to the steering whee\
l hub where it will be clearly visible to
the driver.
