To inspect or replace the filter:
1. Remove the two screws on the top of the engineair cleaner/filter cover.
2. Lift up the outboard side of the cover at an angle while pulling toward you. This is necessary due to
the two hinges located on the inboard side of the
cover.
3. Remove the engine air cleaner/filter and any loose debris that may be found in the air cleaner base.
4. Inspect or replace the air filter element. To reinstall the cover:
1. Align the two hinges located on the inboard side of the cover.
2. Push the cover slightly down and towards the engine to engage the tabs in the hinges and align
the two screws.
3. Tighten the two screws on the top of the engine air cleaner/filter cover.
{WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. Use caution when
working on the engine and do not drive with the
air cleaner/filter off.
Notice: If the air cleaner/filter is off, dirt can easily
get into the engine, which could damage it. Always
have the air cleaner/filter in place when you are
driving.

Notice:Using abrasive cleaners when cleaning
glass surfaces on the vehicle, could scratch the
glass and/or cause damage to the rear window
defogger. When cleaning the glass on the vehicle,
use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in the vehicle's breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning the vehicle's
interior, maintain adequate ventilation by opening the
vehicle's doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Products that remove odors from the vehicle's
upholstery and clean the vehicle's glass can be
obtained from your dealer.
Do not clean the vehicle using:
.A knife or any other sharp object to remove a soil
from any interior surface.
.A stiff brush. It can cause damage to the vehicle's
interior surfaces.
.Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
.Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide. Use only
mild, neutral-pH soaps.
.Too much cleaner that saturates the upholstery.
.Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle's interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be
used on floor carpet and carpeted floor mats. For any
soil, always try to remove it first with plain water or club
soda. Before cleaning, gently remove as much of the
soil as possible using one of the following techniques:
.For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the paper
towel until no more can be removed.
.For solid dry soils: remove as much as possible
and then vacuum.
To clean: 1. Saturate a lint-free, clean white cloth with water or club soda.
2. Wring the cloth to remove excess moisture.
