Maintenance and Care
Inspect the temporary spare tire at least monthly to make sure it is
properly inflated and stored.
The temporary spare tire is easier to handle because of its con struc-
tion which is lighter and smaller than a conventional tire. Thi s tire
should be used only for an emergency and only for a short dista nce.
Use the temporary spare tire o nly until the conventional tire is
repaired, which should be as soon as possible.
Refer to Tires on P. 553.
●The temporary spare tire condition gradually deteriorates even if it has
not been used.
●Tires degrade over time, even when they are not being used on t he
road. It is recommended that tires generally be replaced when t hey are
6 years or older. Heat caused by hot climates or frequent high loading
conditions can accelerate the aging process. You should replace the
spare tire when you replace the other road tires due to the agi ng of the
spare tire. The period in which the tire was manufactured (both week
and year) is indicated by a 4-digit number.
Refer to Tire Labeling on P. 522.
Proper tire balancing provides t he best riding comfort and help s
reduce tread wear. Out-of-balance tires can cause vibration and
uneven wear, such as c upping and flat spots.
When replacing a wheel, make sure the new one is the same as th e orig-
inal factory wheel in diameter, rim width, and offset (inset/outset).
For details, contact your Toyota dealer.
Temporary Spare Tire
NOTICE
●Do not use your temporary spare tire rim with a snow tire or a conven-
tional tire. Neither will properly fit and could damage both tire and rim.
●The temporary spare tire has a tread life of less than 3,000 mi les
(5,000 km). The tread life may be shorter depending on driving condi-
tions.
●The temporary spare tire is for limited use, however, if the tr ead wear
solid-band indicator appears, replace the tire with the same ty pe of
temporary spare ( P. 417).

Overheating
If the high engine coolant temperature warning light turns on:
Drive safely to the side of the road and park off the right-of-way.
Put a vehicle with an automatic t ransaxle in park (P), a manual tran-
saxle in neutral.
Apply the parking brake.
Turn off the air conditioner.
Check whether coolant or steam is escaping from the engine com-
partment.
If steam is coming from the engine compartment
Do not go near the front of t he vehicle. Stop the engine.
Wait until the steam dissipates, then open the hood and start the
engine.
If neither coolant nor steam is escaping
Open the hood and idle the engine until it cools.
Make sure the cooling fan is operating, then turn off the engin e after
the temperature has decreased.
When cool, check th e coolant level.
If it is low, look for coolant lea ks from the radiator and hoses.
■If you find a leak or other damage, or if coolant is still leak ing:
Stop the engine and call your Toyota dealer.
Cooling fan
Cooling system cap
Coolant reservoir
If the high engine coolant temperature warning light turns on,
the vehicle loses power, or you hear a loud knocking or pinging
noise, the engine is probably too hot.

inspected.
Contact Your Toyota Dealer and Have Vehicle Inspected
SignalWarning
Master Warning Light The light turns on when the system has a malfunction.
Operate the center display and verify the content.
Refer to If a Warning Light Turns On or Flashes on P. 489.
ABS Warning LightIf the ABS warning light stays on while you’re driving, the
ABS control unit has detected a system malfunction. If this
occurs, your brakes will function normally as if the vehicle
had no ABS.
Should this happen, consult your Toyota dealer as soon as
possible.
Check Engine Light
If this light illuminates while driving, the vehicle may have
a problem. It is important to note the driving conditions
when the light illuminated and consult your Toyota dealer.
The check engine light may illuminate in the following
cases:
• The fuel tank level being very low or approaching empty.
• The engine’s electrical system has a problem.
• The emission control system has a problem.
• The fuel-filler cap is missing or not tightened securely.
If the check engine light remains on, or it flashes continu-
ously, do not drive at high speeds and consult your Toyota
dealer as soon as possible.

If Trouble Arises
WARNING
■Never tamper with the air bag/pr etensioner systems and always h ave
your Toyota dealer perform all servicing and repairs
Self-servicing or tampering with the systems is dangerous. An a ir bag/pre-
tensioner could accidentally activate or become disabled causin g serious
injury or death.
■
If the tire pressure monitoring system warning light illuminate s or
flashes, or the tire pressure warning beep sound is heard, decr ease
vehicle speed immediately and avoid sudden maneuvering and
braking
If the tire pressure monitoring system warning light illuminate s or
flashes, or the tire pressure war ning beep sound is heard, it is danger-
ous to drive the vehicle at high speeds, or perform sudden mane uvering
or braking. Vehicle drivability co uld worsen and result in an accident.
To determine if you have a slow leak or a flat, pull over to a safe position
where you can check the visual condition of the tire and determ ine if you
have enough air to proceed to a place where air may be added an d the
system monitored again by your Toyota dealer or a tire repair s tation.
■Do not ignore the TPMS Warning Light
Ignoring the TPMS warning light is dangerous, even if you know why it
is illuminated. Have the problem taken care of as soon as possi ble
before it develops into a more serious situation that could lea d to tire
failure and a dangerous accident.
NOTICE
■ Automatic Transaxle Warning Light
If the automatic transaxle warning light illuminates, the trans axle has an
electrical problem. Continuing to drive your Toyota in this condition could
cause damage to your transaxle. Consult your Toyota dealer as s oon as
possible.
■ KEY Warning Light
If the key warning indicator light illuminates or the push button start indicator
light (amber) flashes, the engine may not start. If the engine cannot be
started, try starting it using the emergency operation for star ting the engine,
and have the vehicle inspected at your Toyota dealer as soon as possible.

■Low Fuel Warning Light
The light illumination timing may vary because fuel inside the fuel tank moves
around according to the driving conditions and the vehicle post ure.
■ Seat Belt Warning Light
●The warning light flashes for about 6 seconds if the driver’s s eat belt is not
fastened when the ignition is switched ON.
● To allow the front passenger occupant classification sensor to function prop-
erly, do not place and sit on an additional seat cushion on the front passen-
ger’s seat. The sensor may not function properly because the ad ditional
seat cushion could cause sensor interference.
● If a small child is seated on the front passenger’s seat, the warning light may
not operate.
■ Tire Pressure Monitoring System Warning Light
●
Perform tire pressure adjustment when the tires are cold. Tire pressure
will vary according to the tire temperature, therefore let the vehicle stand
for 1 hour or only drive it 1 mile (1.6 km) or less before adju sting the tire
pressures. When pressure is adjusted on hot tires to the cold i nflation
pressure, the TPMS warning light/beep may turn on after the tir es cool
and pressure drops below specification.
Also, an illuminated TPMS warning light, resulting from the tire air pres-
sure dropping due to cold ambient temperature will remain illum inated
even if the ambient t emperature rises. In this case, it will also be neces-
sary to adjust the tire air pressures. If the TPMS warning ligh t illuminates
due to a drop in tire air pressure, make sure to check and adju st the tire
air pressures.
●Tires lose air naturally over time and the TPMS cannot tell if the tires are
getting too soft over time or you have a flat. However, when you find one
low tire in a set of four-that is an indication of trouble; you should have
someone drive the vehicle slowly forward so you can inspect any low
tire for cuts and any metal objects sticking through tread or s idewall. Put
a few drops of water in the valve stem to see if it bubbles ind icating a
bad valve. Leaks need to be addressed by more than simply reinf lating
the tire as leaks are dangerous - take it to your Toyota dealer .
