Maintenance and care
CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident
resulting in death
or serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed ti res (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Do not tow if your vehicle has a compact spare tire installed.
■When initializing the tire pressure warning system (vehicles with a
tire pressure warning system)
Do not operate the tire pressure wa rning reset switch without first adjust-
ing the tire inflation pr essure to the specified level. Otherwise, the tire
pressure warning light may not come on even if the tire inflation pressure
is low, or it may come on when the ti re inflation pressure is actually nor-
mal.

■ After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. ( →P. 286)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle.
Because certain bulbs are connected to circuits designed to prevent over-
load, non-genuine parts or parts non designed for this vehicle may be unus-
able.
