Allow inspection and repairs to be performed by a Toyota dealer
● Toyota technicians are well-trained specialists and are kept up to date
with the latest service information. They are well informed about the
operations of all systems on your vehicle.
● Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty coverage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly
take care of it.
CAUTION
■Warning in handling of battery
●Engine exhaust, some of its constituents, and a wide variety of automobile
components contain or emit chemicals known to the State of California to
cause cancer and birth defects and other reproductive harm. Work in a
well ventilated area.
● Oils, fuels and fluids contained in vehicles as well as waste produced by
component wear contain or emit chemicals known to the State of
California to cause cancer and birth defects or other reproductive harm.
Avoid exposure and wash any affected area immediately.
● Battery posts, terminals and related accessories contain lead and lead
compounds which are known to cause brain damage. Wash your hands
after handling. ( P. 450)

CAUTION
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 fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after 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 or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or 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 experience discomfort, see a doctor.
● Do not touch the engine compartment when the electric cooling fan is
operating.
The electric cooling fan may keep rotating for about 3 minutes even after
the engine switch is turned to the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant
temperature is high. Be sure the engine switch is in the “LOCK” position
and that the electric cooling fan is completely stopped when working near
the electric cooling fan or radiator grille.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

Maintenance and care
CAUTION
■
When raising your vehicle
Make sure to observe the following to reduce the possibility of death or\
seri-
ous injury.
●Do not use the jack that was supplied with your vehicle.
● Do not put any part of your body or get underneath the vehicle supported
only by the floor jack.
Always use automotive jack stands on a solid, level surface.
● Do not start the engine while the vehicle is supported by the floor jack.
● Stop the vehicle on level firm ground, firmly set the parking brake and shift
the shift lever in P.
● Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
● Do not raise the vehicle while someone is in the vehicle.
● When raising the vehicle, do not place any objects on top of or underneath
the floor jack.
●Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
● More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
● A new engine consumes more oil.
● When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
● Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per
1000 km)
● If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600
miles (1000 km), contact your Toyota dealer.
■ Changing the engine oil (U.S.A. only)
To reset the oil change system, follow the procedure below:
Turn the engine switch to the “ACC” or “LOCK” position with the
odometer reading shown. ( P. 174)
While pressing the trip meter reset button, turn the engine switch to
the “ON” position.
Continue to press and hold the button until the trip meter displays
“000000”.
CAUTION
■ Used engine oil
●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
● Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call your Toyota dealer, service station or auto parts store for
information concerning recycling or disposal.
● Do not leave used engine oil within the reach of children.

between the “MAX” and “MIN”
lines on the tank.
“MAX”
“MIN”
CAUTION
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and may cause
burns.
■ When the electric cooling fan is operating
Do not touch the engine compartment.
The electric cooling fan may keep rotating for about 3 minutes after the
engine switch is turned to the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. Be sure the engine switch is in the “LOCK” position and that
the electric cooling fan is completely stopped when working near the ele\
ctric
cooling fan or radiator grille.

The fluid level should be within the appropriate range.
Full (when cold)
Add fluid (when cold)
Full (when hot)
Add fluid (when hot)
Hot: Vehicle has been driven around 50 mph (80 km/h) for 20 minutes, or slightly longer in cold temperatures. (Fluid tem-
perature, 140 F - 175F [60C - 80 C])
Cold: Engine has not been run for about 5 hours. (Room tempera- ture, 50 F - 85F [10C - 30C])
■ Checking the fluid level
Make sure to check the fluid type and prepare the necessary items.
Clean all dirt off the reservoir.
Remove the reservoir cap by turning it counterclockwise and
wipe the dipstick clean.
Reinstall the reservoir cap.
Remove the reservoir cap again and look at the fluid level.
