Cabin air filter
[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system...
Before Entering the Vehicle
Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.
Remove frost, snow, or ice.
Visually check the tires for uneven
wear and damage.
Check under the vehicle for any sign
of leaks...
