Maintenance and care
WARNING
■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 makes, 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 tires (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.
■ When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure 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 tire inflation pressure is actually normal.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
■ While towing
●When towing using cables or chains, avoid sudden starts, etc. which place
excessive stress on the towing eyelet, cables or chains. The towing eyelet,
cables or chains may become damaged, broken debris may hit people and
cause serious damage.
● Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
■ Installing towing eyelets to the vehicle
●The towing eyelets are only for the vehicle equipped with them. Do not use
the towing eyelets for another vehicle, and do not use the towing eyelets
for this vehicle on another vehicle.
● Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
