The initialization operation
●Make sure to carry out in
itialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold be fore carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch off during initialization,
it is not necessary to press the reset switch again as initialization will
restart automatically when the engine switch to the “ON” position (vehi-
cles without a smart key system) or IGNITION ON mode (vehicles with a
smart key system) for the next time.
●If you accidentally press the reset s witch when initialization is not neces-
sary, adjust the tire inflation pressu re to the specified level when the
tires are cold, and conduct initialization again.
■Warning performance of the ti re pressure warning system
The warning of the tire pressure warning system will change in accor-
dance with driving conditions. For th is reason, the system may give a
warning even if the tire pressure does not reach a low enough level, or if
the pressure is higher than the pressure that was adjusted to when the
system was initialized.
■When initialization of the tire pr essure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicle inspected by your Toyota dealer.
●When operating the initialization of th e system, the tire pressure warning
light does not blink 3 times and the setting message does not appear on
the multi-information display.
●After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.

If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light
frequently comes on after blinking for
1 minute when the engine switch is tu rned to the “ON” position (vehicles
without smart key system) or IGNITI ON ON mode (vehicles with smart
key system), have it checked by your Toyota dealer.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place 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 braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steerin g system warning light comes on
When the light comes on yellow, the assist to the power steering is
restricted. When the light comes on red, the assist to the power steering is
lost and handling operations of the steering wheel become extremely
heavy. When steering wheel operations are heavier than usual, grip the
steering wheel firmly and operate it using more force than usual.
■
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
inflation pressure immediately.
●If the tire pressure warning light co mes on even after tire inflation pres-
sure 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.

Vehicles without a smart key system:
Maintain the engine speed of the second vehicle and turn the
engine switch to the “ON” position, then start the vehicle’s engine.
Vehicles with a smart key system:
Maintain the engine speed of the second vehicle and turn the
engine switch to IGNITION ON mode, then start the vehicle’s
engine.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
To install the engine cover, conduct the removal procedure in
reverse. After installing, check that the fixed pins are inserted
securely.
Once the engine starts, have the v ehicle inspected at your Toyota
dealer as soon as possible.
■ Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the air conditioning system while the engine is
stopped.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When exchanging the battery
●Use a battery that conforms to European regulations.
● Use a battery that the case size is same as the previous one (LN2), 20 hour
rate capacity (20HR) is equivalent ( 60Ah) or greater, and performance rating
(CCA) is equivalent (520A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi- cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
● For details, consult your Toyota dealer.
