WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
■Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Fail-ure to do so may lead to an accident,
resulting in death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or restricted lane due to con-
struction work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc., are
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.
●When your vehicle is towing a trailer or during emergency towing.
■Preventing LTA system malfunc-tions and operations performed by mistake
●Do not modify the headlights or place stickers, etc., on the surface of the lights.
●Do not modify the suspension, etc. If the suspension, etc., needs to be
replaced, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not install or place anything on the hood or grille. Also, do not
install a grille guard (bull bars, kan- garoo bar, etc.).
●If your windshield needs repairs, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■Conditions in which functions
may not operate properly
In the following situations, the func- tions may not operate properly and
the vehicle may depart from its lane. Drive safely by always paying careful attention to your surroundings and
operate the steering wheel to correct the path of the vehicle without relying solely on the functions.
●When the follow-up cruising dis-play is displayed ( P.248) and the
preceding vehicle changes lanes. (Your vehicle may follow the pre-ceding vehicle and also change
lanes.)

WARNING
■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.
■If the tire pressure warning light comes on
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.
●Vehicles with a compact spare tire and full-size spare tire: If the tire
pressure warning light comes on even after tire inflation 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 any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Vehicles with emergency tire punc-ture repair kit: If the tire pressure
warning light comes on even after tire inflation pressure adjustment, it is probable that you have a flat tire.
Check the tires. If a tire is flat, repair the flat tire by using emergency tire puncture repair kit.
●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 leak-age should occur
The tire pressure warning system
may not activate immediately.
NOTICE
■To ensure the tire pressure warn- ing system operates properly
Do not install tires with different speci- fications or makers, as the tire pres-sure warning system may not operate
properly.

7-2. Steps to take in an emergency
Stop the vehicle in a safe place
on a hard, flat surface.
Set the parking brake.
Shift the shift lever to P.
Stop the hybrid system.
Turn on the emergency flashers.
( P.426)
For vehicles with power back
door: Turn off the power back
door system. ( P.151)
Check the degree of the tire
damage.
Do not remove the nail or screw
from the tire. Removing the object
may widen the opening and make
emergency repair with the repair kit
impossible.
• A tire should only be repaired
with the emergency tire puncture
repair kit if the damage is caused
by a nail or screw passing
through the tire tread.
• To avoid sealant leakage, move
the vehicle until the area of the
puncture, if known, is positioned
at the top of the tire.
If you have a flat tire
(vehicles with an emer-
gency tire puncture
repair kit)
Your vehicle is not equipped
with a spare tire, but instead is
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.
The sealant can be used only
once to temporarily repair one
tire without removing the nail
or screw from the tire.)
Depending on the damage, this
kit cannot be used to repair the
tire. ( P.448)
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.

valve and transmitter may not operate properly. If a liquid sealant is used, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer or other qualified ser-vice shop as soon as possible. After
use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing
or replacing the tire. ( P.394)
