■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering sys- tem warning light may come on and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: →P. 3 2 5
If none of the tires are punctured: Turn the engine switch off then turn it to
ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks
for approximately 1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immedi- ately.
If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization. ( →P.282)
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light (after a few minutes).
■Conditions that the tire pressure
warning system may not function properly

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place
immediately and contact any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer.

an accident resulting in death or seri- ous injury.
■When the electric power steer-ing 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.

Be sure to observe the following pre-
cautions. 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.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.

If you have a flat tire
Your vehicle is not equipped

equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily using the emergency tire
puncture repair kit. (The kit
contains a bottle of sealant.

once to temporarily repair one
tire without removing the nail
or screw from the tire.)

kit cannot be used to repair the
tire. ( →P.326)
After temporarily repairing the
tire with the kit, have the tire
repaired or replaced by any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer. Repairs
conducted using the emer-
gency tire puncture repair kit
are only a temporary measure.
Have the tire repaired and
replaced as soon as possible.
WARNING
■If you have 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, which could
result in an accident.

rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the engine when the bat- tery is discharged
The engine cannot be started by push-

■To prevent battery discharge
●Turn off the headlights and the audio
system while the engine is stopped.
●Turn off any unnecessary electrical
components when the vehicle is run-

When trouble arises
ning at a low speed for an extended
period, such as in heavy traffic.
■When the battery is removed or dis- charged
●Information stored in the ECU is cleared. When the battery is depleted, have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Some systems may require initializa-tion. ( →P.369)
■When removing the battery termi-
nals
When the battery terminals are removed, the information stored in the
ECU is cleared. Before removing the battery terminals, contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehi-
cle is not in use, due to natural dis- charge and the draining effects of certain electrical appliances. If the vehi-
cle 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 recharging or replacing the battery
●In some cases, it may not be possible to unlock the doors using the smart entry & start system when the battery
is discharged. Use the wireless remote control or the mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a mal-function.
●The engine switch mode is memo-rized by the vehicle. When the battery
is reconnected, the system will return to the mode it was in before the bat-tery was discharged. Before discon-
necting the battery, turn the engine
switch off. If you are unsure what mode the engine switch was in before the bat-
tery discharged, be especially careful when reconnecting the battery.
■When replacing the battery
●Use a genuine battery specifically designed for use with the Stop & Start system or a battery with equivalent
specifications to a genuine battery. If an unsupported battery is used, Stop & Start system functions may be
restricted to protect the battery. Also, battery performance may decrease and the engine may not be able to
restart. Contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer for details.
●Use a battery that conforms to Euro-pean regulations.
●Use a battery that the case size is same as the previous one, 20 hour
rate capacity (20HR) is equivalent or greater, and performance rating (CCA) is equivalent or greater. Check
the label on top of the battery for the battery size and specifications (ex. LN3, 65Ah, 600A).
• 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 bat-tery may discharge and the engine
may not be able to start.
●Use a ventilation type calcium battery
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
battery. • Use the exhaust hose that was attached to the battery before replac-
ing and confirm that it is firmly con- nected to the hole section of the vehicle.
• Use the exhaust hole plug included with the battery replaced or the one installed on the battery prior to the
replacement. (Depending on the bat- tery to be replaced, the exhaust hole
