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.
Checking the battery

■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.

5827-3. 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.628)
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
( P.89)
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
operate properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-support ed run-flat tire
is equipped.
• If a window tint that affects the radio wave signals is installed.

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 not 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), driver’s seat position sen-
sor, driver’s seat belt buckle switch,
front passenger occupant classifica-
tion system (ECU and sensors),

necting wiring and power sources.
(  P.36)
■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 o ff after several
driving trips.
If the light does not go off even after
several trips, contact your Toyota
dealer as soon as possible.
■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.637
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 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
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.584)
■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 ca se, 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-
