When driving
NOTICE
Pre-driving check
Trapping small animals in the cooling fan and belts of the engine may result
in a malfunction. Check that no small animal enters the engine compartment
and under the vehicle before starting the engine.
When driving the vehicle
Vehicles with an automatic transmission
Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
Vehicles with a manual transmission
Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
Do not shift gears unless the clutch pedal is fully depressed. After shifting,
do not release the clutch pedal abruptly. Doing so may damage the clutch,
transmission and gears.
Observe the following to prevent the clutch from being damaged.
• Do not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
• Do not use any gear other than the 1st gear when starting off and mov-
ing forward.
Doing so may damage the clutch.
• Do not use the clutch to hold the vehicle when stopping on an uphill
grade.
Doing so may damage the clutch.
Do not shift the shift lever to R when the vehicle is still moving. Doing so
may damage the clutch, transmission and gears.
Do not release the clutch pedal too quickly. Doing so may damage the
transmission.
When parking the vehicle (vehicles with an automatic transmission)
Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is acci-
dentally depressed.

246 3-1. Using the air conditioning system and defogger
Fogging up of the windows
Vehicles with the button: The windows will easily fog up when the
humidity in the vehicle is high. Turning
on will dehumidify the air
from the outlets and defog the windshield effectively.
Vehicles with the button: If you turn
off, the windows may
fog up more easily.
The windows may fog up if the recirculated air mode is used.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the
outside/recirculated air mode button to the recirculated air mode. This is
recommended to prevent outside air from entering the vehicle interior.
Vehicles with the button: During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
When the outside temperature falls to nearly 0°C (32°F) (vehicles with
the button)
The dehumidification function may not operate even when is
pressed.

254 3-1. Using the air conditioning system and defogger
Using automatic mode
Fan speed is adjusted automatically according to the temperature setting
and the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
If you turn
off, the windows may fog up more easily.
The windows may fog up if the recirculated air mode is used.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the
outside/recirculated air mode button to the recirculated air mode. This is
effective in preventing outside air from entering the vehicle interior.
During cooling operation, setting the recirculated air mode will also cool
the vehicle interior effectively.
Outside/recirculated air mode may automatically switch depending on
the temperature setting or the inside temperature.
When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when
is
pressed.

296 4-3. Do-it-yourself maintenance
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.

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.

306 4-3. Do-it-yourself maintenance
Coolant selection
Only use “TOYOTA Genuine 50/50 Pre-mixed Super Long Life Coolant
BLUE” or similar high-quality ethylene glycol-based non-silicate, non-amine,
non-nitrite, and non-borate coolant with long-life hybrid organic acid technol-
ogy.
“TOYOTA Genuine 50/50 Pre-mixed Super Long Life Coolant BLUE” is a
mixture of 50% coolant and 50% deionized water. (Enabled: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
CAUTION
When the engine is hot
Do not remove the radiator cap.
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 engine coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture 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.

422 5-2. Steps to take in an emergency
CAUTION
To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
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
not operate, the window may interfere with the vehicle body, possibly
scratching both the vehicle body and window, or even shattering the window.

5-2. Steps to take in an emergency
When trouble arises
If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine and call any authorized Toyota dealer or
repairer, or another duly qualified and equipped profes-
sional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.STEP 1
