WARNING
■If the hybrid system has to be turned off while driving
Turning the hybrid system off while driving will not cause a loss of steer-ing or braking control. However,
power assist for the steering wheel may be lost making it difficult to steer smoothly before stopping the vehicle
depending on the remaining charge in the 12-volt battery or usage condi-tions. Decelerate as much as possible
before turning off the hybrid system.
If the vehicle is sub-
merged or water on the
road is rising
This vehicle is not designed to
be able to drive on roads that
are deeply flooded with water.
Do not drive on roads where
the roads may be submerged
or the water may be rising. It is
dangerous to remain in the
vehicle, if it anticipated that the
vehicle will be flooded or set a
drift. Remain calm and follow
the following.

5308-2. Steps to take in an emergency
When using a flat-bed truck to
transport the vehicle, use tire strap-
ping belts. Refer to the owner’s
manual of the flat-bed truck for the
tire strapping method.
In order to suppress vehicle move-
ment during transportation, set the
parking brake and turn the power
switch off.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using cables or
chains secured to the emergency
towing eyelets. This should only be
attempted on hard surfaced roads
for short distances at under 30
km/h (18 mph).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in
good condition.
WARNING
■When towing the vehicle
Be sure to transport the vehicle with
all four wheels raised off the ground. If the vehicle is towed with the tires contacting the ground, the drivetrain
or related parts may be damaged, the vehicle may fly off the truck, or elec-tricity generated by the operation of
the motor may cause a fire to occur depending on the nature of the dam-age or malfunction.
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
●Do not tow the vehicle from the rear when the power switch is off. The steering lock mechanism (if
equipped) is not strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for tow-ing at the opposite end of the raised
vehicle. Without adequate clear- ance, the vehicle could be dam-aged while being towed.
■Towing with a sling-type truck
Do not tow with a sling-type truck to prevent body damage.

When trouble arises
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.492)
■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).
■When a tire is replaced with a com-pact spare tire (vehicles with com-
pact spare tire)
The compact spare tire is not equipped with a tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure warning light will not turn off even though the flat tire has been
replaced with the spare tire. Replace the spare tire with the standard tire and adjust the tire inflation pressure. The tire
pressure warning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function
properly

WARNING
■If a warning light comes on or a
warning buzzer sounds when a
warning message is shown on
the multi-information display*
Check and follow the message shown
on the multi-information display.
Failure to do so may result in death or serious injury.*: Warning lights illuminate in red or
yellow and the warning buzzer
beeps once or sounds continu-
ously.
■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. If the steering wheel becomes heavier than usual when operating, hold firmly
and operate 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.
●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 authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
