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.

Warning (Continued)
overheat warning. The engine
could catch fire and you or others
could be burned. Use a 50/
50 mixture of clean, drinkable
water and DEX-COOL coolant.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Help keep the proper engine
temperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
for the cooling system. See
Recommended Fluids and
Lubricants 0335.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down.
If coolant is visible but the coolant
level is not at or above the mark
pointed to, add a 50/50 mixture of
clean drinkable water and
DEX-COOL coolant.
Be sure the cooling system is cool
before this is done.
If no coolant is visible in the coolant
surge tank, add coolant as follows:

3. Fill the coolant surge tank withthe proper DEX-COOL coolant
mixture to the indicated
level mark.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator
hose getting hot. Watch out for
the engine cooling fans.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
DEX-COOL coolant mixture to the coolant surge tank until the
level reaches the indicated
level mark.
5. Replace the pressure cap tightly.
Check the level in the coolant surge
tank when the cooling system has
cooled down. If the coolant is not at
the proper level, repeat Steps 1–
3 and reinstall the pressure cap.
If the coolant still is not at the proper
level when the system cools down
again, see your dealer.
Engine Overheating
There is a coolant temperature
gauge on the instrument cluster that
indicates an overheated engine
condition. See Engine Coolant
Temperature Gauge 0117.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Assistance
Program 0346.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface. Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If not, do not
continue to run the engine and have
the vehicle serviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
See
Overheated Engine
Protection Operating Mode 0266

safe place in an emergency.
If Steam Is Coming from the
Engine Compartment
See Overheated Engine Protection
Operating Mode 0266 for

266 Vehicle Care
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem might not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
. Stops after high-speed driving.
. Idles for long periods in traffic.
. Tows a trailer.
If the overheat warning displays with
no sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the
highest fan speed. Open the
windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral), and let the
engine idle.
If the coolant temperature gauge is
no longer in the overheat zone, the
vehicle can be driven. Continue to drive the vehicle slowly for about
10 minutes. Keep a safe vehicle
distance from the vehicle in front.
If the warning does not come back
on, continue to drive normally and
have the cooling system checked
for proper fill and function.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
Overheated
Engine Protection Operating
Mode 0266.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
allows the vehicle to be driven to a
safe place in an emergency
situation. If an overheated engine
condition exists, an overheat
protection mode which alternates
firing groups of cylinders helps prevent engine damage. In this
mode, there is significant loss in
power and engine performance.
The engine coolant temperature
gauge indicates if an overheat
condition exists. Driving extended
distances and/or towing a trailer in
the overheat protection mode
should be avoided.
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.
