by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it
was in before the battery was discon-
nected. Make sure to turn off the engine before disconnecting the bat-
tery. Take extra care when connecting
the battery if the engine switch mode prior to discharge is unknown.
If the system will not start even after
multiple attempts, contact any author- ized Toyota retailer or Toyota authorized

4307-3. Do-it-yourself maintenance
Replace the tires if the treadwear indi-
cators are showing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating inter-
nal damage
●A tire goes flat repeatedly or cannot
be properly repaired due to the size or location of a cut or other damage
If you are not sure, consult with any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if
it has seldom or never been used or
damage is not obvious.
■Low profile tires (17-inch tires and 18-inch tires)
Generally, low profile tires will wear
more rapidly and tire grip performance will be reduced on snowy and/or icy
roads when compared to standard tires.
Be sure to use snow tires or tire chains
on snowy and/or icy roads and drive carefully at a speed appropriate for road
and weather conditions.
■If the tread on snow tires wears
down below 4 mm (0.16 in.)
The effectiveness of the tires as snow
tires is lost.
■Checking the tire valves
When replacing the tires, check the tire valves for deformat ion, cracks, and
other damage.
WA R N I N G
■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 result-
ing 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 a compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
