4-3. Do-it-yourself maintenance
3 Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. (→P. 246)
Initializing the tire pressure warning system
n
Initialize the tires with the tire inflation pressure adjusted to the specified
level.
If you push the tire pressure warning reset switch accidentally
n
If initialization is performed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.
When the initialization of the tire pressure warning system has
n
failed
Initialization can be completed in several minutes. However, in the fol-
lowing cases, the settings have not been recorded and the system will
not operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
When operating the tire pressure warning reset switch, the tire pres-
l
sure warning light does not flash 3 times.
After carrying out the initialization procedure, the tire pressure warn-
l
ing light blinks for 1 minute and then stays on after driving for about
20 minutes.
Routine tire inflation pressure checks
n
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
