CAUTION
When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system: Be sure the engine switch is
off. With the engine switch in the “ON” position, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 307)
Vehicles with a smart entry & start system: Be sure the “ENGINE START
STOP” switch is off. With the “ENGINE START STOP” switch in IGNITION
ON mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the coolant temperature is high. (P. 307)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

298 4-3. Do-it-yourself maintenance
CAUTION
Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
NOTICE
When opening the hood
Do not lift up or operate the wipers. Doing so may cause the hood and wip-
ers to contact, scratching the hood.
Use caution when opening the engine hood in windy weather as it may
close suddenly in strong wind.
Do not attach any accessories other than genuine Toyota products to the
engine hood. Such additional weight on the engine hood may cause it to
be too heavy to be supported by the supporting rod when opened.
When closing the hood
Do not apply excessive weight or force when closing the hood as doing so
may result in damage.

300 4-3. Do-it-yourself maintenance
CAUTION
When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
When using a floor jack, follow the instructions of the manual provided with
the jack.
Do not use the jack that was supplied with your vehicle.
Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
Always use floor jack and/or automotive jack stands on a solid, flat, 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 to P (vehicles with an automatic transmission) or R (vehicles
with a manual transmission).
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 object on top of or underneath
the floor jack.
When raising the vehicle, ensure that there is sufficient surrounding space.
The vehicle’s position may change slightly when lowered.
Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than five minutes for the oil to
drain back into the bottom of the engine.
Hold a rag under the end and
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check
the oil level.
When checking the oil, look at both sides of the dipstick and use the

Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.
When the engine is new, for example directly after purchasing the vehicle
or after replacing the engine
If low quality oil or oil of an inappropriate viscosity is used
When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
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 any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information
concerning recycling or disposal.
Do not leave used engine oil within the reach of children.

Maintenance and care
Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Reservoir cap
“FULL”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
NOTICE
To prevent serious engine damage
Check the oil level on a regular basis.
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 level on the dipstick every time you refill the vehicle.
Be sure the engine oil filler cap is properly tightened.
If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap,
drain cock and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional pressure test the cap and
check for leaks in the cooling system.
