2014 TOYOTA SEQUOIA air condition

490 4-3. Do-it-yourself maintenance
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.
■ When working near the cooling fans or radiator grille
Be sure the engine switch is in the LOCK position.
With the engine switch on, the cooling fans may automatically start to run if
the air conditioning is on and/or the coolant temperature is high.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

500 4-3. Do-it-yourself maintenance
Radiator and condenserCheck the radiator and condenser and clear any foreign objects.
If either of the above parts are ex tremely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the MAX and MIN lines
on the reservoir.
■ Adding fluid
Make sure to check the fluid type and prepare the necessary items.
CAUTION
■ When the engine is hot
Do not touch the radiator or condenser as they may be hot and may cause
serious injuries, such as burns.
Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.

514 4-3. Do-it-yourself maintenance
CAUTION
■When initializing the tire pressure warning system
Do not push the tire pressure warnin g reset switch without first adjusting
the tire inflation pressure to the spec ified level. Otherwise, the tire pres-
sure warning light may not come on ev en if the tire inflation pressure is
low, or it may come on when the tire inflation pressure is actually normal.
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
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled cor-
rectly.
●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 se alants, 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. 509)
■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 pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

518 4-3. Do-it-yourself maintenance
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 resu lting 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 reinstall the tire valve caps.
Without the valve caps, dirt or mo isture could get into the valve and
cause air leakage, which could result in an accident. If the caps have
been lost, replace them as soon as possible.

4-3. Do-it-yourself maintenance
Air conditioning filter
The air conditioning filter must be changed regularly to maintain air
conditioning efficiency.
■ Replacement method
Turn the engine switch off.
Open the glove box.
Remove the internal tray.
Remove the inside cover by
sliding up while pulling toward
you.

Maintenance and care
Remove the filter cover.
Pull the filter out of the filter
outlet.
Remove the air conditioning
filter and replace it with a new
one.
The
“  UP” marks shown on the
filter should be pointing up.

524 4-3. Do-it-yourself maintenance
■Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas wit h heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to
the “Scheduled 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 air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.
