Maintenance and care
Do not forget to check the spare.
■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation
pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked b y your Toyota
dealer.
■Instructions for checking tire
inflation pressure
When checking tire inflation pres-
sure, observe the following:
●Check only when the tires are
cold.
If your vehicle has been parked
for at least 3 hours or has not
been driven for more than 1 mile
or 1.5 km, you will get an accurate
cold tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is
properly inflated based only on its
appearance.
●It is normal for the tire inflation
pressure to be higher after driving
as heat is generated in the tire. Do
not reduce tire inflation pressure
after driving.
●Never exceed the vehicle capacity
weight. Passengers and luggage
weight should be placed so that
the vehicle is balanced.
WARNING
■Proper inflation is critical to
save tire performance
Keep your tires properly inflated.
If the tires are not properly
inflated, the following conditions
may occur which could lead to an
accident resulting in death or seri-
ous injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire
and wheel
●Wheel deformation and/or tire
damage
●Greater possibi lity of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing tire inflation pressure
Be sure to put the tire valve caps
back on.
If a valve cap is no t installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.

5148-2. Steps to take in an emergency
The rear passengers’ seat belt w arning buzzer sounds to alert the rear
passengers that his o r her seat belt is not fastened. If the se at belt is
unfastened, the buzzer sounds intermittently for a certain peri od of time,
after the seat belt is fastened and unfastened and the vehicle reaches a
certain speed.
■Warning buzzer
In some cases, the buzzer may not
be heard because of noisy place or
an audio sound.
■Front passenger detection sen-
sor, seat belt reminder and
warning buzzer
●If luggage is placed on the front
passenger seat, the front passen-
ger detection sensor may cause
the warning light to flash and the
warning buzzer to sound even if a
passenger is not sitting in the
seat.
●If a cushion is placed on the seat,
the sensor may n ot detect a pas-
senger, and the warning light may
not operate properly.
■SRS warning light
This warning light system monitors
the airbag sensor assembly, front
impact sensors, side impact sensors
(front door), side impact sensors
(front), side impact sensors (rear),
driver’s seat position sensor, front
passenger occupant classification
sensors, “AIR BAG ON” indicator
light, “AIR BAG OFF” indicator light,
front passenger’s seat belt buckle
switch, driver’s seat belt preten-
sioner, front passenger’s seat belt
pretensioner and force limiter, air-
bags, interconnecting wiring and
power sources. ( P.35)
■If the malfunction indicator
lamp comes on while driving
First check the following:
●Is the fuel t ank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely. The light will go off after several
driving trips.
If the light does not go off even after
several trips, con
tact your Toyota
dealer as soon as possible.
■Electric power steering system
warning light (warning buzzer)
When the 12-volt battery charge
becomes insufficien t or the voltage
temporarily drops, the electric power
steering system warning light may
come on and the warning buzzer
may sound.
At this time, the functions of the air
conditioning, etc. may be partially
limited in order to reduce the power
consumption of the 12-volt battery.
■When the tire pressure warning
light comes on (vehicles with
tire pressure warning system)
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P.522
If none of the tires are punctured:
Turn the power switch to OFF then
turn it to ON. Check if the tire pres-
sure warning light comes on or
blinks.
If the tire pressur e 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 your
Toyota dealer immediately.
If the tire pressur e warning light
comes on
1 After the temperature of the tires
has lowered sufficiently, check
the inflation pressure of each tire

5168-2. Steps to take in an emergency
●If the tire pressure warning light
comes on even after tire infla-
tion 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 Toyota dealer.
●Avoid abrupt maneuvering and
braking. If the vehicle tires dete-
riorate, you could lose control of
the steering wheel or the
brakes.
■If a blowout or sudden air
leakage should occur (vehi-
cles with tire pressure warn-
ing system)
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
(vehicles with tire pressure
warning system)
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label (tire and
load information label). (If your
vehicle has tires of a different size
than the size indicated on the
vehicle placard or tire inflation
pressure label [tire and load infor-
mation label], you should deter-
mine the proper tire inflation
pressure for those tires.)
WARNING
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS-tire pressure warning sys-
tem) that illuminates a low tire
pressure telltale (tire pressure
warning light) w hen one or more
of your tires is s ignificantly under-
inflated. Accord ingly, when the
low tire pressure te lltale (tire pres-
sure warning light) illuminates,
you should stop and check your
tires as soon as possible, and
inflate them to the proper pres-
sure. Driving on a significantly
under-inflated tire causes the tire
to overheat and can lead to tire
failure. Under-inflation also
reduces fuel efficiency and tire
tread life, and may affect the vehi-
cle’s handling and stopping abil-
ity.
Please note that the TPMS (tire
pressure warning system) is not a
substitute for proper tire mainte-
nance, and it is the driver’s
responsibility to m aintain correct
tire pressure, even if under-infla-
tion has not reached the level to
trigger illumination of the TPMS
low tire pressure te lltale (tire pres-
sure warning light).

When trouble arises
One of the following may be the
cause of the problem:
The AC charging cable may
be attached to the vehicle.
( P.123)
 The electronic key may not be
functioning properly.
( P.532)
 There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle. ( P.304)
 There may be a malfunction
in the immobilizer system.
( P.71)
 The hybrid system may be
malfunctioning due to an elec-
trical problem such as elec-
tronic key battery depletion or
a blown fuse. However,
depending on the type of mal-
function, an interim measure
is available to start the hybrid
system. ( P.530)
NOTICE
■Be careful when driving over
bumps with the compact
spare tire installed on the
vehicle
The vehicle height may become
lower when driving with the com-
pact spare tire compared to when
driving 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 com-
pact spare tire.
Tire chains may damage the vehi-
cle body and adversely affect driv-
ing performance.
■When replacing the tires
(vehicles with tire pressure
warning system)
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.
If the hybrid system
will not start
Reasons for the hybrid sys-
tem not starting vary
depending on the situation.
Check the following and
perform the appropriate
procedure:
The hybrid system will not
start even though the cor-
rect starting procedure is
being followed ( P.277)

5328-2. Steps to take in an emergency
2Pull the lever.
■When the electronic key does
not work properly
●Make sure that the smart key sys-
tem has not been deactivated in
the customization setting. If it is
off, turn the function on.
(Customizable features: P.570)
●Check if battery-saving mode is
set. If it is set, cancel the function.
( P.218)
●The electronic key function may
have stopped. ( P.218)
NOTICE
■When opening the fuel filler
door manually
●Do not open the fuel filler door
manually except in an emer-
gency. Fuel may overflow.
●Using the lever to open the fuel
filler door may n ot allow for an
adequate reduction in fuel tank
pressure before refueling. To
prevent fuel from spilling out,
turn the cap slowly when remov-
ing it.
●During refueling, fuel may spill
out from the filler opening due to
air being discharged from inside
the fuel tank. Therefore, fill the
fuel tank carefully and slowly.
If the electronic key
does not operate prop-
erly
If communication between
the electronic key and vehi-
cle is interrupted ( P.218)
or the electronic key cannot
be used because the battery
is depleted, the smart key
system and wireless remote
control cannot be used. In
such cases, the doors can
be opened and the hybrid
system can be started by
following the procedure
below.
NOTICE
■In case of a smart key system
malfunction, o r other key
related problems
Take your vehicle with all the
electronic keys provided with your
vehicle to your Toyota dealer.

5599-1. Specifications

Vehicle specifications
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha
t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
