vehicle.
When the battery is discon-
nected or discharged
Readiness codes that are set

Also, depending on your driving
habits, the readiness codes may
not be completely set.
When the fuel tank cap is
loose
The malfunction indicator lamp
comes on indicating a temporary
malfunction and your vehicle may
not pass the I/M test.
The error code in the OBD sys-
tem will not be cleared unless
the vehicle is driven 40 or more
times.
Contact your Toyota dealer to
prepare the vehicle for re-test-
ing.
Emission inspection
and mainte nance (I/M)
programs
Some states have vehicle
emission inspection pro-
grams which include OBD
(On Board Diagnostics)
checks. The OBD system
monitors the operation of
the emission control sys-
tem.
If the malfunc tion indica-
tor lamp comes on
Your vehicle may not pass
the I/M test in the follow-
ing situations:
When the malfunction
indicator lamp still
remains on after several
driving trips
If your vehicle does not
pass the I/M test

ItemsParts and toolsWARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the engine
compartment
●Keep hands, clothing and tools
away from the moving fans and
engine drive belt.
●Be careful not to touch the
engine, radiator, exhaust mani-
fold, etc. right a fter driving as
they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
●Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fans or radiator
grille
Be sure the engine switch is off.
With the engine switch in ON, the
electric cooling fans may auto-
matically start to r un if the air con-
ditioning is on an d/or the coolant
temperature is high. ( P.308)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.

■Adding fluid
Make sure to check the fluid
type and prepare the necessary
item.

Item
Clean funnel
■Brake fluid can absorb moisture
from the air
Excess moisture in the brake fluid
can cause a dangerous loss of brak-
ing efficiency. Use only newly
opened brake fluid.
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.
Hold-down clamp

WARNING
■When filling the reservoir
Take care as brake fluid and
clutch fluid can harm your hands
and eyes and damage painted
surfaces. If fluid gets on your
hands or in your eyes, flush the
affected area with clean water
immediately.
If you still experi ence discomfort,
see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level
to go down slight ly as the brake
pads wear out or when the fluid
level in the accumulator is high.
If the reservoir needs frequent
refilling, there m ay be a serious
problem.

■Checking battery fluid
Check that the level is between
the “UPPER LEVEL” and
“LOWER LEVEL” lines.
“UPPER LEVEL” line
“LOWER LEVEL” line
If the fluid level is at or below the
“LOWER LEVEL” line, add distilled
water.
■Adding distilled water
1 Remove the vent plug.
2 Add distilled water.
If the “UPPER LEVEL ” line cannot
be seen, check the fluid level by
looking directly at the cell.
3 Put the vent plug back on
and close it securely.
■Before recharging
When recharging, t he battery pro-
duces hydrogen ga s which is flam-
mable and explosive. Therefore, observe the following before
recharging:
●If recharging with 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
The engine may not start. Follow the
procedure below to initialize the sys-
tem.
1 Shift the shift lever to P (auto-
matic transmission) or depress
the brake pedal with the shift
lever in N (manual transmission).
2 Open and close either door.
3 Restart the engine.
●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 vehi cle will return the
engine switch mode to the status it
was in before the battery was dis-
connected. Make sure to turn off
the engine before disconnecting
the battery. Take extra care when
connecting the battery if the
engine switch mode prior to the
battery being disconnected is
unknown.
If the system will not start even after
multiple attempts, contact your Toy-
ota dealer.

steps listed.
■Checking interval
Inspect and replace the air condi-
tioning filter according to the mainte-
nance schedule. In dusty areas or
areas with heavy traffic flow, early
replacement may be required. (For
scheduled maintenance information,
please refer to the “Owner’s Manual
Supplement” or “Scheduled Mainte-
nance”.)
■If air flow from the vents
decreases dramatically
The filter may be clogged. Check
the filter and replace if necessary.
■If the electronic key battery is
depleted
The following symptoms may occur:
●The smart key system and wire-
less remote control will not func-
tion properly.
●The operational range will be
reduced.
 Flathead screwdriver
