inflation pressure TOYOTA TACOMA 2023 Owner's Manual

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.

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.

4887-2. Steps to take in an emergency
WARNING
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s res ponsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicato r to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) mal func-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-ups
as long as the malfunction exists . When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tir e pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure w arning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
NOTICE
■To ensure the tire pressure warning system operates properly (i f
equipped)
Do not install tires with differ ent specifications or makers, a s the tire
pressure warning system may not operate properly.

When trouble arises
Indicates that the accelerator and brake pedals
are being depressed simultaneously, and the
Brake Override System is operating. (
P. 170)
 Release the accelerator pedal and depress
the brake pedal.
(If equipped)
Indicates that the tire inflation pressure is low.
 Check the tire inflation pressure, and
adjust to the appropriate level.
(Canada only)
Indicates that the washer fluid level is low.
Add washer fluid.
Indicates that remaining fuel is approximately
3.2 gal. (12.0 L, 2.6 Imp.gal.) or less
 Refuel the vehicle.

When trouble arises
■The temporary spare tire
●Your vehicle is equipped with a temporary spare tire that may be a differ-
ent size, tread type, and/or manufacturer from the ground tires installed
on your vehicle.
●The temporary spare tire is iden tified by the “TEMPORARY USE ON LY ”
marking on the disc wheel and/or the tire sidewall.
Use the temporary spare tire temp orarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the temporary spare
tire. ( P. 5 5 1 )
■After completing the tire change (vehicles with the tire pressu re
warning system)
The tire pressure warni ng system must be reset. ( P. 433)
■When using the temporary spare tire (vehicles with the tire pre ssure
warning system)
As the temporary spare tire is no t equipped with the tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
indicated by the tire pressure warning system. Also, if you rep lace the
temporary spare tire after the tire pressure warning light come s on, the
light remains on.
■If you have a flat rear tire on a road covered with snow or ice
Install the temporary spare tire on one of the front wheels of the vehicle.
Perform the following steps and f it tire chains to the rear tires:
Replace a front tire with the temporary spare tire.
Replace the flat rear tire with the tire removed from the front of the
vehicle.
Fit tire chains to the rear tires.
