molded into the sidewall of each tire.
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
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 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 deformation, cracks, and other damage.
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 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.
NOTICE
■Low profile tires
Low profile tires may cause greater damage than usual to the tire wheel when sustaining impact from the road
surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated, they may be damaged more
severely.
●Avoid potholes, uneven pavement,
curbs and other road hazards. Fail- ure to do so may lead to severe tire and wheel damage.

When trouble arises
WARNING
■After recharging the battery
Have the battery inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
If the battery is deteriorating, contin- ued use may cause the battery to emit a malodorous gas, which may be
detrimental to the health of passen- gers.
■When replacing the battery
●For information regarding battery replacement, contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●After replacing, securely attach the exhaust hose and exhaust hole
plug to the exhaust hole of the replaced battery. If not properly installed, gases (hydrogen) may
leak into the vehicle interior, and there is the possible danger of the gas igniting and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper cables,
ensure that they do not become entangled in the cooling fan or engine drive belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal
is to be used when charging the bat- tery from another vehicle in an emer-gency. It cannot be used to jump start

When trouble arises
engine coolant is unavailable.
6Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan
operate and to check for coolant
leaks from the radiator or hoses.
The fan operate when the air condition-
ing system is turned on immediately after a cold start. Confirm that the fan is operating by checking the fan sound
and air flow. If it is difficult to check these, turn the air conditioning system on and off repeatedly. (The fan may not
operate in freezing temperatures.)
7 If the fan is not operating: Stop
the engine immediately and
contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The
engine compartment may be very hot.
●Keep hands and clothing (espe-cially a tie, a scarf or a muffler) away from the fan and belts. Failure
to do so may cause the hands or clothing to be caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the engine and radiator
are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.
