Maintenance and care
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced safety
●Damage to the drive train
●Reduced tire life due to wear
●Reduced fuel economy
●Reduced driving comfort and poor
handling
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Instructions for checking tire infla-tion pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire inflation pressure reading.
●Always use a tire pressure gauge.It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the tire inflation pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
WARNING
■Proper inflation is critical to save
tire performance
Keep your tires properly inflated. If the tires are not properly inflated,
the following conditions may occur which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire dam-age
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges on the road, etc.)
NOTICE
■When inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air leak, resulting in
decreased tire inflation pressure.

6-4. Do-it-yourself maintenance
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
z Wheels of different sizes or types
z Used wheels
z Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be
installed. ( →P.281)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.

WARNING
■When replacing wheels
●Do not use wheels that are a differ-
ent size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leak-ing wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or serious injury.
■When installing the wheel nuts
Never use oil or grease on the wheel
bolts or wheel nuts. Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and
the wheel may fall off, causing an accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
■Use of defective wheels prohib-ited
Do not use cracked or deformed
wheels. Doing so could cause the tire to leak air during driving, possibly causing an accident.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. In addition, make sure to purchase your tire pressure warn-
ing valves and transmitters at any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.

warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering sys- tem warning light may come on and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: →P. 3 2 5
If none of the tires are punctured: Turn the engine switch off then turn it to
ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks
for approximately 1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immedi- ately.
If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization. ( →P.282)
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light (after a few minutes).
■Conditions that the tire pressure
warning system may not function properly
→ P. 2 8 0
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place
immediately and contact any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer.
The vehicle will become extremely unstable during braking, and the ABS system may fail, which could cause
an accident resulting in death or seri- ous injury.
■When the electric power steer-ing system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the light comes on
red, the assist to the power steering is lost and handling operations of the steering wheel become extremely
heavy. When steering wheel operations are heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following pre-
cautions. Failure to do so could cause a loss of vehicle control and result in death or
serious injury.
●Stop your vehicle in a safe place as
soon as possible. Adjust the tire inflation pressure immediately.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.

13Inflate the tire until the specified
air pressure is reached.
The sealant will be injected and
the pressure will spike to 300
kPa (3.0 kgf/cm2 or bar, 44 psi)
or 400 kPa (4.0 kgf/cm2 or bar,
58 psi), then gradually
decrease.
The air pressure gauge will dis-
play the actual tire inflation pres-
sure about 1 to 5 minutes after
the switch is turned on.
z Turn the compressor switch off
and then check the tire inflation
pressure. Being careful not to
over inflate, check and repeat
the inflation procedure until the
specified tire inflation pressure is
reached.
z The tire can be inflated for about
5 to 20 minutes (depending on
the outside temperature). If the
tire inflation pressure is still lower
than the specified point after
inflation for 25 minutes, the tire is
too damaged to be repaired.
Turn the compressor switch off
and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
z If the tire inflation pressure
exceeds the specified air pres-
sure, let out some air to adjust
the tire inflation pressure.

the luggage compartment while
it is connected to the compres-
sor.
18 To spread the liquid sealant
evenly within the tire, immedi-
ately drive safely for about 5 km
(3 miles) below 80 km/h (50
mph).
19 After driving, stop your vehicle in
a safe place on a hard, flat sur-
face and reconnect the repair
kit.
Remove the air release cap from the hose before reconnecting the hose.
20 Turn the compressor switch on
and wait for several seconds,
then turn it off. Check the tire
inflation pressure.
If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm2 or
bar, 19 psi): The puncture can-
not be repaired. Contact any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
If the tire inflation pressure is
130 kPa (1.3 kgf/cm2 or bar, 19
psi) or higher, but less than the
specified air pressure: Proceed
to step 21.
If the tire inflation pressure is the
specified air pressure ( →P.357):
Proceed to step 22.
21 Turn the compressor switch on
to inflate the tire until the speci-
fied air pressure is reached.

23 Store the bottle in the luggage
compartment while it is con-
nected to the compressor.
24 Taking precautions to avoid sud-
den braking, sudden accelera-
tion and sharp turns, drive
carefully at under 80 km/h (50
mph) to the nearest Toyota
dealer that is less than 100 km
(62 miles) away for tire repair or
replacement.
When having the tire repaired or replaced, make sure to tell any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer that the sealant is injected.
■If the tire is inflated to more than the specified air pressure
1 Disconnect the hose from the valve.
2 Install the air release cap to the end of the hose and push the protrusion
on the air release cap into the tire valve to let some air out.
3 Disconnect the hose from the valve,
remove the air release cap from the hose and then reconnect the hose.
4 Turn the compressor switch on and wait for several seconds, and then
turn it off. Check that the air pressure indicator shows the specified air pressure. ( →P.357)
If the air pressure is under the desig- nated pressure, turn the compressor switch on again and repeat the inflation
procedure until the specified air pres- sure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emer- gency tire puncture repair kit, the valve should be replaced.
■After a tire is repaired with the
emergency tire puncture repair kit
●The tire pressure warning valve and
transmitter should be replaced.
●Even if the tire inflation pressure is at
the recommended level, the tire pres- sure warning light may come on/flash.
WARNING
■Do not drive the vehicle with a
flat tire
Do not continue driving with a flat tire. Driving even a short distance with a
flat tire can damage the tire and the wheel beyond repair.
Driving with a flat tire may cause a cir-
cumferential groove on the side wall. In such a case, the tire may explode when using a repair kit.
■When fixing the flat tire
●Stop your vehicle in a safe and flat
area.
