ute.
After 2 minutes, registration of a second wheel set is being performed. The tire
pressure warning light will turn off and “--” will be displayed for the inflation pressure of each tire on the multi-infor-
mation display.
6 Initialize the tire pressure warn-
ing system. ( P.337)
If the tire inflation pressure settings for
the installed tire changes, initialization operations are required, but if the same tire inflation pressure, initialization is
not required.
7 Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Registration of a second wheel set is complete when the tire pressure warn-
ing light turns off and the inflation pres- sure of each tire is displayed on the multi-information display.

Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. ( P. 4 2 7 )

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 drivetrain
●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.

6-3. 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:
Wheels of different sizes or types
Used wheels
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.336)
■When removing the wheel orna-
ment (vehicles with a wheel cap clip)
Remove the wheel ornament using the
wheel cap clip*.*: The wheel cap clip is installed in the
glove box. ( P.298)
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.
Wheel selection
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
●Be sure to install the wheel nuts with the tapered ends facing inward ( P.402). Installing the nuts with
the tapered ends facing outward can cause the wheel to break and eventually cause the wheel to come
off while driving, which could lead to an accident resulting in death or serious injury.

1 Remove the key cover.
To prevent damage to the key, cover the tip of the flathead screwdriver with a
rag.
2 Remove the battery cover.
Use a screwdriver of an appropriate size. Forcedly prying may cause the
cover damaged.
If the battery cover is difficult to remove, lift the edge to remove it.
3 Remove the depleted battery
using a small flathead screw-
driver.
When removing the battery, use a screwdriver of an appropriate size.
Insert a new battery with the “+” termi-
nal facing up.
4 Install the battery cover with the
tab facing up.
Push the entire edge of the battery
cover into the key.
