CAUTION
■When working near the electric cooling fans or radiator grille
Vehicles without a smart key 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 temperature is high. ( P. 544)
Vehicles with a smart key system
Be sure the engine switch is off. With the engine switch in IGNITION ON
mode, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 544)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your 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.

Maintenance and care
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with the tire pressure warn-
ing system)
●When removing or fitting the wheels, ti res or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pressure
warning valves and transmitters may be damaged if not handled correctly.
● Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the tire
pressure warning valves could be bound.
● When replacing tire valve caps, do not use tire valve caps other than those
specified. The cap may become stuck.
■ To avoid damage to the tire pressure warning valves and transmitters
(vehicles with the tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
your Toyota dealer or other qualified service shop as soon as possible.
Make sure to replace the tire pressure warning valve and transmitter when
replacing the tire. ( P. 553)
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressure that is even just a few p ounds off can affect ride quality and
handling.
●Do not reduce tire inflation pressure after driving. It is normal for tire
inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated . Otherwise, the following conditions
may occur and result in an accident causing death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts result ing from overheated tires
●Poor sealing of the tire bead
●Wheel deformation and/or tire separation
●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and
cause air leakage, which could result in an accident. If the caps are lost,
replace them as soon as possible.

Air conditioning filter
Vehicles without a smart key system: Turn the engine switch to the
“LOCK” position.
Vehicles with a smart key system: Turn the engine switch off.
Open the glove box. Slide off
the damper.
Push in each side of the glove
box to disconnect the claws.
Remove the filter cover.
The air conditioning filter must be changed regularly to maintain
air conditioning efficiency.

Maintenance and care
Remove the air conditioning fil-
ter and replace it with a new
one.
The “UP” marks shown on the fil-
ter should be pointing up.
■ Changing interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to the
“Owner’s Manual Supplement” or “Scheduled Maintenance”.)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.

NOTICE
■When using the ai r conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.

When trouble arises
7-2. Steps to take in an emergency
If your vehicle overheats
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled down sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant
leaks, immediately contact your
Toyota dealer.
The following may indicate that your vehicle is overheating.
● The high engine coolant temperature warning light ( P. 615) comes
on or a loss of engine power is experienced. (For example, the
vehicle speed does not increase.)
● Steam comes out from under the hood.
