WARNING
●In the event that battery fluid
comes into contact with the skin
or eyes, immediately wash the
affected area with water and
seek medical attention. Place a
wet sponge or cloth over the
affected area until medical
attention can be received.
●Always wash your hands after
handling the battery support,
terminals, and other bat-
tery-related parts.
●Do not allow child ren near the
battery.
■To prevent damage to the
vehicle
Do not pull- or push-start the vehi-
cle as the three-way catalytic con-
verter may overheat and become
a fire hazard.
NOTICE
■When handling jumper cables
Be careful that the jumper cables
do not become tangled in the
cooling fans or any of the belts
when connecting or disconnecting
them.
■When closing the doors
While pushing the door glass
towards the inside of the vehicle,
slowly close the door.
Because the side window
open/close function linked to door
operation will no t operate, the
window may inte rfere with the
vehicle body, possibly scratching
both the vehicle body and win-
dow, or even shattering the win-
d o w.
If your vehicle over-
heats
The following may indicate
that your vehicle is over-
heating.
 The engine coolant tem-
perature gauge ( P.88) is
in the red zone or a loss of
engine power is experi-
enced. (For example, the
vehicle speed does not
increase.)
 “High Coolant Temperature
Check Owner's Manual” is
shown on the multi-informa-
tion display.
 Steam comes out from
under the hood.

7
When trouble arises
hoses and radiator core (radi-
ator) for any leaks.
Radiators
Cooling fans
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
4 The coolant level is satisfac-
tory if it is between the
“FULL” and “LOW” lines on
the reservoir.

Radiator cap
5 Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail- able.
6
Start the engine and turn the
air conditioning system on to
check that the radiator cool-
ing fans operate and to check
for coolant leaks from the
radiator or hoses.
The fans operate when the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fans are operating by
checking the fan sound and air flow.
If it is difficult to check these, turn
the air conditioning system on and
off repeatedly. (The fans may not
operate in freezing temperatures.)
7If the fans are not operating:
Stop the engine immediately
and contact your Toyota
dealer.
If the fans are operating:
Have the vehicle inspected at
the nearest Toyota dealer.

WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions.
Failure to do so may result in seri-
ous injury such as burns.

with no detriment to engine durab ility or driveability.
■Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used whe n changing
the engine oil. Warm up and turn off the engine, wait more than 5 min-
utes, and check the oil level on the dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is
used in your Toyota vehicle. Use
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to
satisfy the following grade and
viscosity.
Oil grade: ILSAC GF-5 multi-
grade engine oil
Recommended viscosity: SAE
0W-20
SAE 0W-20 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change. Outside temperature
Oil viscosity (0W-20 is explained
here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil
which allows cold startability.
Oils with a lower value before
the W allow for easier starting
of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the
oil when the oil is at high tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if
the vehicle is operated at high
speeds, or under extreme
load conditions.
