tires TOYOTA PRIUS 2004 2.G Owner's Manual

294 When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire infla-
tion pressure, improper wheel align-
ment, out−of −balance wheels, or se-
vere braking.
CAUTION
Do not include a compact spare
tire when rotating the tires. It is
designed for temporary use only.
WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Do not use snow tires other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which could cause loss of
vehicle control.
When storing removed tires, you should
store them in a cool dry place.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.
Installing snow tires and
chains

295
TIRE CHAIN SELECTION
Use the tire chains of correct size.
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check local reg-
ulations before installing chains.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten
chains after driving 0.5—1.0 km
(1/4—1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tire, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.
Replacing wheels

296
Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.When installing aluminum wheels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles).
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only Toyota wheel nuts and
wrench designed for your aluminum
wheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.

Spark ignition system ofyour Toyota
The spark ignition system in your
Toyota meets all requirements of
the Canadian Interference −Causing
Equipment Standard.
Installation of a mobile twoway radio system
As the installation of a mobile
two −way radio system in your ve-
hicle could affect electronic sys-
tems such as multiport fuel injec-
tion system / sequential multiport
fuel injection system, cruise con-
trol system, anti −lock brake sys-
tem, vehicle stability control sys-
tem, SRS airbag system, seat belt
pretensioner system and Toyota
hybrid system, be sure to check
with your Toyota dealer for pre-
cautionary measures or special
instructions regarding installation.
Tires and loading on your Toyota
Underinflated or overinflated
tire inflation pr essure and the
excess load may result in the
deterioration of steering ability
and braking ability, leading to
an accident. Check the tire
inflation pressure periodically
and be sure to keep the load
limits given in this Owner ’s
Manual. For details about tire
inflation pressure and load lim-
its, see page 289 and pages
224.
