Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter reduces dust, pollen, and other
airborne irritants from outside air
that is pulled into the vehicle. The
filter will need to be replaced
periodically. SeeMaintenance
Schedule 0326.
Using the climate control system
without an air filter installed is not
recommended. Water or other
debris could enter the system and
result in leaks or noises. Always
install a new filter when removing
the old filter.
For more information on filter
replacement, see your dealer.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0258.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle must be on level ground. The
engine oil dipstick handle is a loop.
See
Engine Compartment Overview
0 253 for the location of the engine
oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull out the dipstick and wipe it with a clean paper towel or
cloth, then push it back in all
the way. Remove it again,
keeping the tip down, and
check the level.

Engine Air Cleaner/Filter
The engine air cleaner/filter is in the
engine compartment on the
passenger side of the vehicle. See
Engine Compartment
Overview0253.
When to Inspect the Engine Air
Cleaner/Filter
For intervals on changing and
inspecting the engine air cleaner/
filter, see Maintenance
Schedule 0326.
How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have the
engine running with the engine air
cleaner/filter housing open. Before
removing the engine air cleaner/
filter, make sure that the engine air
cleaner/filter housing and nearby
components are free of dirt and
debris. Remove the engine air
cleaner/filter. Lightly tap and shake
the engine air cleaner/filter (away
from the vehicle), to release loose
dust and dirt. Inspect the engine air
cleaner/filter for damage, and replace if damaged. Do not clean
the engine air cleaner/filter or
components with water or
compressed air.
To inspect or replace the engine air
cleaner/filter:
2.5L L4 Engine
1. Screws
2. Electrical Connector
3. Air Duct Clamp
1. Open the hood. See
Hood 0252.
2. Remove the five screws (1) on top of the engine air cleaner/
filter housing. 3. Disconnect the electrical
connector (2).
4. Disconnect the outlet duct by loosening the air duct
clamp (3).
5. Lift the filter cover housing away from the engine air
cleaner/filter housing.
6. Pull out the filter.
7. Inspect or replace the engine air cleaner/filter.
8. Reverse Steps 2-5 to reinstall the filter cover housing.

2. Secondary Air Hose (IfEquipped)
3. Electrical Connector
4. Air Duct Clamp
To inspect or replace the engine air
cleaner/filter:
1. Open the hood. See Hood 0252.
2. Remove the seven screws (1) on top of the engine air
cleaner/filter housing.
3. Disconnect the secondary air hose (2) (if equipped).
4. Disconnect the electrical connector (3).
5. Disconnect the outlet duct by loosening the air duct
clamp (4).
6. Lift the filter cover housing away from the engine air
cleaner/filter housing.
7. Pull out the filter.
8. Inspect or replace the engine air cleaner/filter.
9. Reverse Steps 2-5 to reinstall the filter cover housing.
{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.
Caution
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.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.

under the best conditions, the
engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and
filter must be changed at least once
a year and the oil life system must
be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
