“TOYOTA Genuine 50/50 Pre-mixed
Super Long Life Coolant BLUE” is a mix- ture of 50% coolant and 50% deionized
water. (Minimum temperature: -35°C
[-31°F])
For more details about engine coolant,
contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain
cock and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.
Check the radiator and condenser
and clear away any foreign objects.
If either of the above parts is
extremely dirty or you are not sure
of their condition, have your vehicle
inspected by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
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.

■When the engine is hot
Do not remove the engine coolant reservoir cap. ( P.364)
The cooling system may be under
pressure and may spray hot coolant if the cap is removed, causing serious
injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication,
corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to
prevent it from damaging parts or
paint.

“UPPER LEVEL” line
“LOWER LEVEL” line
If the fluid level is at or below the
“LOWER LEVEL” line, add distilled
water.
■Adding distilled water

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, the battery produces
hydrogen gas which is flammable and
explosive. Therefore, observe the fol- lowing 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 system.
1 Shift the shift lever to P (automatic
transmission) or depress the brake pedal with the shift lever in N (man-
ual transmission).
2 Open and close either door.
3 Restart the engine.
●Unlocking the doors using the smart
entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical
key to lock/unlock the doors.
●Start the engine with the engine
switch in ACC. The engine may not start with the engine switch turned off.
However, the engine will operate nor-
mally from the second attempt.
●The engine switch mode is recorded
by the vehicle. If the battery is discon- nected and reconnected, the vehicle
will return the engine switch mode to
the status it was in before the battery was disconnected. Make sure to turn
off the engine before disconnecting
the battery. Take extra care when con- necting the battery if the engine switch
mode prior to the battery being dis-
connected is unknown.
If the engine will not start even after mul-
tiple attempts, contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped profes-
sional.

when working near the battery.
●Keep children away from the bat-
tery.
■Where to safely charge the bat-
tery
Always charge the battery in an open
area. Do not charge the battery in a
garage or closed room where there is insufficient ventilation.
■Emergency measures regarding electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge or cloth while traveling to the nearest
medical facility.
●If electrolyte gets on your skin

fire if spilled on the engine, etc.
NOTICE
■Do not use any fluid other than
washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the
vehicle’s painted surfaces, as well as damaging the pump leading to prob-
lems of the washer fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as nec-
essary.

Maintenance and care
Rotate the tires in the order shown.
Front
To equalize tire wear and extend tire
life, Toyota recommends that tire rota-
tion is carried out at the same interval
as tire inspection.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
 The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-infor-
mation display.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and
a warning light. ( P.342)
■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 of daily
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display
the tire inflation pressure after the
engine switch is turned to ON. It may also take a few minutes to display the
tire inflation pressure after inflation
NOTICE
■If tire inflation pressure of each
tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
■Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in
tire inflation pressure, reducing the cushioning ability of the tires. In addi-
tion, driving on rough roads may
cause damage to the tires them- selves, as well as the vehicle’s
wheels and body.

■Registering ID codes
The ID codes of the tire pressure warn- ing valve and transmitters for two sets of
wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels
of both normal tires and snow tires are registered beforehand.
In addition to the set of tire pressure
warning system sensor ID codes initially registered to the vehicle, a second set of
ID codes can be registered.
A second set of tire pressure warning system sensor ID codes can be regis-
tered at your Toyota dealer or repairer,
or another duly qualified and equipped professional. When 2 sets of ID codes
have been registered, either ID code set
can be selected.
1 Park the vehicle in a safe place
and turn the engine switch to
ON.
2 Press the tire pressure warning
reset switch 3 times within 3
seconds.
3 The tire pressure warning light
will illuminate for 3 seconds and
then blink 3 times.
4 The tire pressure warning light
will blink for 1 minute and then
illuminate.
5 When the ID code change has
completed, the tire pressure
warning light will turn off.
Check that tire pressures are displayed
on the multi-information display.
