WARNING
■Caution regarding the use of
windshield wipers in AUTO
mode (vehicles with
rain-sensing windshield wip-
ers)
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in AUTO mode.
Take care that your fingers, etc.
do not become caught in the
windshield wipers.
■Caution regarding the use of
washer fluid
When it is cold, do not use the
washer fluid until the windshield
becomes warm. The fluid may
freeze on the windshield and
cause low visibility. This may lead
to an accident, resulting in death
or serious injury.
NOTICE
■When the washer fluid tank is
empty
Do not operate the switch continu-
ally as the washer fluid pump may
overheat.
■When a nozzle becomes
blocked
In this case, contact your Toyota
dealer.
Do not try to clear it with a pin or
other object. The nozzle will be
damaged.

Maintenance and careThe coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir
when the engine is cold.Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line. (
P.469)
■Coolant selection
Only use “Toyota Super Long Life
Coolant” or a similar high quality
ethylene glycol ba sed non-silicate,
non-amine, non-nitrite, and
non-borate coolant with long-life
hybrid organic acid technology.
U.S.A.:
“Toyota Super Long Life Coolant” is
a mixture of 50% c oolant and 50%
deionized water. (Minimum tem-
perature: -31°F [-35°C])
Canada:
“Toyota Super Long Life Coolant” is
a mixture of 55% c oolant and 45%
deionized water. (Minimum tem-
perature: -44°F [-42°C])
For more details about coolant, con-
tact your Toyota dealer.
■If the coolant level drops within
a short time of replenishing
Visually check the radiator, hoses,
engine coolant reservoir cap, 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 sys-
tem.
NOTICE
■When replacing the engine oil
●Be careful not to spill engine oil
on the vehicle components.
●Avoid overfilling, or the engine
could be damaged.
●Check the oil le vel on the dip-
stick every time you refill the
vehicle.
●Be sure the engine oil filler cap
is properly tightened.
■If oil is spilled on the engine
cover
To prevent the engine cover from
being damaged, remove any
engine oil from the engine cover
as soon as possible using a neu-
tral detergent. Do not use an
organic solvent such as brake
cleaner.
Checking the coolant
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap and radiator cap.
The cooling system may be under
pressure and may spray hot cool-
ant if the cap is removed, causing
serious injuries, such as burns.

engine is hot or running as
washer fluid contains alcohol and
may catch fire if spilled on the
engine, etc.

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 lead-
ing to problems of the washer
fluid not spraying.

Dilute washer fluid with water as
necessary.
