■Setting items
●Setting items are not selectable during driving and cannot be o perated.
Also, the settings screen is temporarily canceled in the follow ing situations.
• A warning message is displayed.
• The vehicle starts off.
● Settings for functions not equipped to the vehicle are not displayed.
● When a function is turned off, the related settings for that fu nction are not
selectable.
■ Pop-up display
In some situations, such as when a switch operation is performe d, a pop-up
display will be temporarily displayed on the multi-information display.
■ When disconnecting and reco nnecting battery terminals
The drive information will be reset.
■ Ending display
When the engine switch is turned off, each of the following wil l be displayed
on the multi-information display, and will extinguish after app roximately
30 seconds.
● Distance traveled
● Average fuel economy
● Distance to empty
■ Tire inflation pressure (vehicles with tire pressure warning sy stem)
● It may take a few minutes to display the tire inflation pressur e after the
engine switch is turned to the “ON” position (vehicles without a smart key
system) or IGNITION ON mode (vehicles with a smart key system). It may
also take a few minutes to display the tire inflation pressure after inflation
pressure has been adjusted.
● “---” may be displayed if the tire position information cannot be determined
due to unfavorable radio wave conditions.
● Tire inflation pressure changes with temperature. The displayed values may
also be different from the values measured using a tire pressur e gauge.
■ Liquid crystal display

Maintenance and care
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to defla te.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation p ressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrec t tire inflation pressure may result in th e following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating , have it checked by your Toyota dealer.

4867-2. Steps to take in an emergency
■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■
When the tire pressure warning light comes on (if equipped)
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressur e warning reset switch will not turn off the tire pressure
warning light.
■The tire pressure warning light may come on due to natural caus es
(if equipped)
The tire pressure warning light may come on due to natural caus es such
as natural air leaks and tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure w ill turn off the
warning light (after several minutes).
■When a tire is replaced with a spare tire (vehicles with the ti re pres-
sure warning system)
The temporary spare tire is not equipped with a tire pressure w arning
valve and transmitter. If a tire goes flat, the tire pressure w arning light will
not turn off even though the flat tire has been replaced with t he temporary
spare tire. Replace the temporary spare tire with the repaired tire and
adjust the tire inflation pressu re. The tire pressure warning l ight will go off
after several minutes.
■Conditions that the tire pressure warning system may not functi on
properly (if equipped)
 P. 4 3 6
■If the tire pressure warning light frequently comes on after bl inking
for 1 minute (if equipped)
If the tire pressure warning light frequently comes on after bl inking for 1
minute when the engine switch is turned to “ON” position (vehic les with-
out a smart key system) or IGNITION ON mode (vehicles with a sm art
key system), have it checked by your Toyota dealer.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy pla ce or an
audio sound.

When trouble arises
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braki ng, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ If the tire pressure warning light comes on (if equipped)
Be sure to observe the following precautions. 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 infla-
tion pressure immediately.
● If the tire pressure warning light comes on even after tire inf lation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If a tire
is flat, change it with the spare tire and have the flat tire repaired by the
nearest Toyota dealer.
● Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur (vehicles with the tire
pressure warning system)
The tire pressure warning system may not activate immediately.
■
Maintenance of the tires (vehicles with the tire pressure warning
system)
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indicated on the vehicle placard or t ire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light)
when one or more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale (tire pressure warni ng light)
illuminates, you should stop and check your tires as soon as po ssible,
and inflate them to the proper pressure. Driving on a significa ntly
under-inflated tire causes the tire to overheat and can lead to tire fail-
ure. Under-inflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
