Maintenance and care
Check the battery as follows.
■Battery exterior
Make sure that the battery termi-
nals are not corroded and that
there are no loose connections,
cracks, or loose clamps.
Terminals
Hold-down clamp
■Before recharging
When recharging, t he battery pro-
duces hydrogen ga s which is flam-
mable and explosive. Therefore,
observe the following precautions
before recharging:
●If recharging wi th the battery
installed on the vehicle, be sure to
disconnect the ground cable.
●Make sure the power switch on
the charger is off when connecting
and disconnecting the charger cables to the battery.
■After recharging/reconnecting
the battery (vehicles with smart
key system)
●Unlocking the doors using the
smart key system may not be pos-
sible immediately
after reconnect-
ing the battery. If this happens,
use the wireless remote control or
the mechanical key to lock/unlock
the doors.
●Start the engine with the engine
switch in ACC. T he engine may
not start with th e engine switch
turned off. However, the engine
will operate normally from the sec-
ond attempt.
●The engine switch mode is
recorded by the vehicle. If the bat-
tery is disconnected and recon-
nected, the vehicle will return the
engine switch mode to the status
it was in before t he battery was
disconnected. Make sure to turn
off the engine switch before dis-
connecting the battery. Take extra
care when connecting the battery
if the engine switch mode prior to
the battery being disconnected is
unknown.
If the engine will no t start even after
multiple attempts, contact your
Toyota dealer.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level
to go down slightly as the brake
pads wear out or when the fluid
level in the accumulator is high.
If the reservoir needs frequent
refilling, there may be a serious
problem.

■Chemicals in the battery
A battery contains poisonous and
corrosive sulfur ic acid and may
produce hydrogen gas which is
flammable and explosive. To
reduce the risk of death or serious
injury, take the following precau-
tions while working on or near the
battery:
●Do not cause sparks by touch-
ing the battery terminals with
tools.

4086-3. Do-it-yourself maintenance
■When rotating the tires (vehi-
cles with tire pressure warning
system)
Make sure that the engine switch is
OFF. If the tires are rotated while
the engine switch i s in ON, the tire
position informa tion will not be
updated. If this accidentally occurs,
either turn the engine switch to OFF
and then to ON, or initialize the sys-
tem after checking that the tire pres-
sure is properly adjusted.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
 If the tire pressure drops
below a predetermined level,
the driver is warned by a
screen display and a warning
light. ( P.455)
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
( P.93)
The illustration used is intended
as an example, and may differ
from the image that is actually
displayed on the multi-informa-
tion display.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks . Make sure to
check tire inflation pressure as part
of your routine o f daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the engine switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after infl ation pressure
has been adjusted.
●Tire inflation pressure changes
with temperature. The displayed
values may also be different from
the values measured using a tire
pressure gauge.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not

When trouble arises
■Tire pressure warning light
■Low fuel level warning light
■Driver’s and front passenger’s seat belt reminder light (warn-
ing buzzer*)
*: Driver’s seat belt warning buzzer:
The driver’s seat belt warning buzzer sounds to alert the drive r that his or
her seat belt is not fastened. Once the engine switch is turned to ON, the
buzzer sounds. If the seat belt is still unfastened, the buzzer sounds inter-
mittently for a certain period o f time after the vehicle reaches a certain
speed.
Front passenger’s seat belt warning buzzer:
The front passenger’s seat belt warning buzzer sounds to alert the front

When the light comes on after blinking for 1 min-
ute:
Malfunction in the tire pressure warning system
Have the system checked by your Toyota
dealer.
When the light comes on:
Low tire inflation pressure such as
 Natural causes
 Flat tire
 Immediately stop the vehicle in a safe
place.
Handling method ( P.457)

When trouble arises
■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes
insufficient or the voltage temporar-
ily drops, the electric power steering
system warning light may come on
and the warning buzzer may sound.
■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.463
If none of the tires are punctured:
Turn the engine switch to OFF then
turn it to ON. Check if the tire pres-
sure 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 insp ected by your
Toyota dealer immediately.
If the tire pressure warning light
comes on
1 After the temperature of the tires
has lowered suff iciently, check
the inflation 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 specified level and perform
initialization. ( P.410)
■The tire pressure warning light
may come on due to natural
causes (vehicles with tire pres-
sure warning system)
The tire pressure warning light may
come on due to natural causes such
as natural air leaks and tire inflation
pressure changes caused by tem-
perature. In this case, adjusting the
tire inflation pressure will turn off the warning ligh
t (after a few minutes).
■When a tire is replaced with a
compact spare tire (vehicles
with tire pressure warning sys-
tem)
The compact spare tire is not
equipped with a tire pressure warn-
ing valve and tran smitter. 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 pres-
sure warning light will go off after a
few minutes.
■Conditions that the tire pres-
sure warning system may not
function properly
 P.408
WARNING
■If a warning light comes on or
a warning buzzer sounds
when a warning message is
shown on the multi-informa-
tion 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
continuously.
