2018 TOYOTA TUNDRA flat tire

5528-2. Steps to take in an emergency
■When the tire pressure warning light comes on
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
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 replace d with a spare tire
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.

■If the tire pressure warning light frequently comes on after bl inking
for 1 minute
If the tire pressure warning light frequently comes on after bl inking for 1
minute when the engine switch is turned to “ON” position, 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 s ystem warning lights remain on
Stop your vehicle in a safe place immediately and contact your To y o t a
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
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 deteriorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
■
Maintenance of the tires
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 indica ted on the vehicle placard or tire 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. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, you should stop and check your tires as soon as possible , and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread lif e, and may
affect the vehicle’s handl ing and stopping ability.

5548-2. Steps to take in an emergency
WARNING
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintena nce, and it is the driver’s responsibility 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 mi nute 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 al ternate 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 sys tem) to
continue to function properly.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with differ ent specifications or makers, a s the tire
pressure warning system may not operate properly.

WARNING
■Using the tire jack
Observe the following precautions.
Improper use of the tire jack may cause the vehicle to suddenly fall off
the jack, leading to death or serious injury.
●Do not use the tire jack for any purpose other than replacing t ires or
installing and removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jack s for
replacing tires on this vehicle.
●Put the jack properl y in its jack point.
●Do not put any part of your body under the vehicle while it is supported
by the jack.
●Do not start the engine or drive the vehicle while the vehicle is sup-
ported by the jack.
●Do not raise the vehicle w hile someone is inside.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a height greater than that required to
replace the tire.

WARNING
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it
from under the vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in
handling the ornament to avoi d unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes imm edi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area
around the brakes will be extreme ly hot. Touching these areas with
hands, feet or other body parts while changing a tire, etc., ma y
result in burns.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the t ire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench as soon as pos-
sible after changing wheels.
Steel wheel: 154 ft·lbf (209 N·m, 21.3 kgf·m)
Aluminum wheel: 97 ft·lbf (131 N·m, 13.4 kgf·m)
• When installing a tire, only use wheel nuts that have been spe cifi-
cally designed for that wheel.
• Retighten the wheel nuts within 100 miles (160 km) of driving.
• If there are any cracks or defo rmations in the bolt screws, nut
threads or bolt holes of the wheel, have the vehicle inspected by
your Toyota dealer.
• Do not attach a heavily damaged wheel ornament, as it may fly off
the wheel while the vehicle is moving.
• When installing the wheel nuts, b e sure to install them with the
tapered ends facing inward. ( P. 5 1 1 )
