CAUTION
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi
cate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale 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
■Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres-
sure warning system may not operate properly.

CAUTION
■Using the tire jack
Improper use of the tire jack may lead to death or injuries due to the
vehicle suddenly falling off the jack.
●Do not use the tire jack for any pu
rpose other than replacing tires or
installing and removing tire chains.
●Only use the tire jack that comes wi th this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jacks for
replacing tires on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not raise the vehicle while someone is in it.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a hei ght greater than that required to
replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
●Do not put any part of your body under the vehicle supported by a jack.
●Do not start or operate the hybrid system while your vehicle is sup-
ported by the jack.
Take particular care when lowering the vehicle to ensure that no one
working on or near the vehicle may be injured.
■Replacing a flat tire
Observe the following precautions to reduce the risk of death or serious
injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
The oil or grease can cause the wheel nuts to loosen, causing a seri-
ous accident. Remove any oil or grease on the wheel bolts or wheel
nuts.
●Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103
N•m, 10.5 kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and
the wheels may fall off, which could lead to an accident causing death
or serious injury.

CAUTION
■When using the compact spare tire
●Remember that your spare tire is specifically designed for use with
your vehicle. Do not use your spare tire on another vehicle.
●Do not use two spare tires simultaneously.
●Replace the compact spare tire with a standard tire as soon as possi-
ble.
●Avoid sudden acceleration, deceleration and braking, as well as sharp
cornering.
■Speed limit when using the compact spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failing
to observe this precaution may lead to an accident causing death or seri-
ous injury.
■When the spare tire is attached
The vehicle speed may not be correctly detected, and the following sys-
tems may not operate correctly:
●ABS & Brake assist
●Enhanced VSC
●Navigation system

NOTICE
■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.
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle
The vehicle becomes lower when driving with the compact spare tire
compared to when drivin
g with standard tires. Be careful when driving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving
performance.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.

If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the sur-
rounding area is clear, to avoid striking other vehicles, objects or persons.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.
NOTICE
■To avoid damaging the transmission and other components
● Avoid spinning the wheels.
● If the vehicle remains stuck after trying these procedures, the vehicle may
require towing to be freed.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow.
Stop the hybrid system. Set t he parking brake and push the
“P” position switch.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the hybrid system.
Carefully apply the accelerator to free the vehicle.STEP1
