checked when pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
•
To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been in
a tightly closed container. Keep the master cylinder
reservoir cap secured at all times. Brake fluid in a open
container absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil unexpect-
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.

WARNING! (Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Power Steering Fluid
Check the fluid level with the vehicle on flat ground and
engine cold. Fluid should be between MIN and MAX
references on the reservoir body.
The level may go over the MAX line when oil is hot.
If topping off is required, make sure the oil you use is
approved. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
256 SERVICING AND MAINTENANCE

WARNING!
Because it is flammable, do not allow the power
steering fluid to come into contact with hot engine
parts
NOTE: Power steering fluid consumption is very low. If
you need to top off your fluid often and multiple times
have your system inspected by your authorized dealer.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE: No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
Avoid using transmission sealers as they may adversely
affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.

IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on the
left front corner of the instrument panel, visible through
the windshield. This number also appears on the vehicle
frame and underbody as well as the Automobile Informa-
tion Disclosure Label affixed to a window on your vehicle,
the vehicle registration and title.
NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the “Brake System Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.
Vehicle Identification Number
290 TECHNICAL SPECIFICATIONS

After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.
FUEL REQUIREMENTS
2.4L Engine
All available gasoline engines are de-
signed to meet all emissions regulations
and provide excellent fuel economy and
performance when using high quality
unleaded “regular” gasoline having a
octane rating of 87 using the (R+M)/2
method. The use of premium gasoline is
not recommended, as it will not provide any benefit over
regular gasoline in these engines.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a
cause for concern. However, if the engine is heard making
a heavy knocking sound, see your dealer immediately. Use
of gasoline with an octane number lower than 87 can cause
engine failure and may void or not be covered by the New
Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consider-
ing service for the vehicle.

292 TECHNICAL SPECIFICATIONS

Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and are specifi-
cally blended to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen-
ates such as ethanol.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the “Malfunction Indicator Light” to
(Continued)
CAUTION!(Continued)
illuminate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than 15%
ethanol (E-15).
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited War-
ranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Gasoline with higher
ethanol content may void the New Vehicle Limited War-
ranty.
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,
the engine will have some or all of these symptoms:
• Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.

TECHNICAL SPECIFICATIONS 293

CNG And LP Fuel System Modifications
Modifications that allow the engine to run on compressed
natural gas (CNG) or liquid propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are
not the responsibility of the manufacturer and may void or
not be covered under the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is
a manganese-containing metallic additive that is blended
into some gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage beyond
gasoline of the same octane number without MMT. Gaso-
line blended with MMT reduces spark plug life and
reduces emissions system performance in some vehicles.
The manufacturer recommends that gasoline without
MMT be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion, and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.Designated TOP TIER Detergent Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, the usage of Top Tier Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
294 TECHNICAL SPECIFICATIONS

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty. NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.
