WARNING
■When working near the electric cooling fan 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 fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. ( →P. 346)
Vehicles with a smart key system: Be sure the engine switch is off. With the
engine switch in IGNITION ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. ( →P. 346)
■ 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.

NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure 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 transmit-
ters
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. 354)
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
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 e ach tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resu lting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire damage
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

Air conditioning filter
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,
and then slowly and fully open
the glove box while supporting
it.
The air conditioning filter must be changed regularly to maintain
air conditioning efficiency.

With the glove box fully open,
slightly lift up the glove box and
pull toward the seat to detach
the bottom of the glove box.
Do not use excessive force if the
glove box does not detach when
lightly pulled. Instead, pull toward
the seat while slightly adjusting the
height of the glove box.
Remove the filter cover.
Remove the air conditioning filter
and replace it with a new one.
The “ \bUP” marks shown on the fil-
ter should be pointing up.

■Checking 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
“Schedule maintenance guide” or “Owner’s Manual Supplement”.)
■ 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 removing the glove box
Always follow the specified procedure to remove the glove box ( →P. 370). If
the glove box is removed without following the specified procedure, the
hinge of the glove box may become damaged.

4147-2. Steps to take in an emergency
C-HR_OM_USA_OM10526U■
Warning light operations for unf astened rear passenger seat belts
● When opening and closing the rear door, the warning light comes on for
approximately 34 seconds.
● When any of the rear seat belts are unfastened, the warning light comes on.
When the rear doors are opened and closed while the warning light is on,
the warning light will turn off after approximately 34 seconds.
■
When the tire pressure warning light comes on
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: → P. 423
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered
sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes, check
that the tire inflation pressure is at the specified level and carry out ini-
tialization. ( →P. 355)
The warning light may come on again if the above operations are con-
ducted without first allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflat ion pressure changes caused by tem-
perature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (afte r a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire ha s been replaced with the spare tire.
Replace the spare tire with the repair ed tire and adjust the tire inflation
pressure. The tire pressu re warning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
