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.
● Vehicles with compact spare tire: Do not tow if your vehicle has a compact
spare tire installed.
● Vehicles with emergency tire puncture repair kit: Do not tow anything if a
tire that has been repaired using t he emergency tire puncture repair kit is
installed. The load on the tire may cause unexpected damage to the tire.
■ 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.

window switch and exit the vehicle through the window.

remain calm, wait until the water level inside the vehicle rises to the
point that the water pressure inside of the vehicle equals the water
pressure outside of the vehicle, and then open the door and exit the
vehicle.

WARNING
■ Using an emergency hammer* for emergency escape
The front side windows and rear side wi ndows, as well as the rear window
can be shattered with an emergency hammer* used for emergency escape.
However, an emergency hammer can not shatter the windshield as it is lam-
inated glass.
*: Contact any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer, or aftermarket accessory manufacturer for further
information about an emergency hammer.
■ Escaping the vehicle from the window
There are cases where escaping the vehicle from the window is not possi-
ble due to seating position, passenger body type, etc.
When using an emergency hammer, consider your seat location and the
size of the window opening to ensure that the opening is accessible and
large enough to escape.
