PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nut/bolt torque for tightness. Check the
tires (including spare) for proper cold inflation pressure.
Lights

Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn signal
and high beam indicator lights on the instrument panel.

Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel or brake fluid leaks are
suspected, the cause should be located and corrected
immediately.
EXHAUST GAS
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system. Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have an authorized dealer inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS

If the vehicle carpet has been removed and
re-installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
 It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
WARNING!
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
 If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
 If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide 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 mainte -
nance. 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.

IN CASE OF EMERGENCY195
6. Remove the wheel bolts and tire.
7. Remove the alignment pin from the jack assembly
and thread the pin into the wheel hub to assist in
mounting the spare tire.

Installing Alignment Pin

8. Mount the spare tire.

Mounting Spare Tire

NOTE:
For vehicles equipped, do not attempt to install a center
cap or wheel cover on the compact spare Úpage 245.
9. Install the wheel bolts with the threaded end of the wheel bolt toward the wheel. Lightly tighten the wheel
bolts.

Installing Wheel Bolts

10. Lower the vehicle to the ground by turning the jack handle counterclockwise.
11. Finish tightening the wheel bolts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern
until each wheel bolt has been tightened twice. If in
doubt about the correct tightness, have them
checked with a torque wrench by an authorized
dealer or at a service station
Úpage 253.
12. After 25 miles (40 km), check the wheel bolt torque with a torque wrench to ensure that all wheel bolts
are properly seated against the wheel.
CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered to the ground. Failure to follow this
warning may result in serious injury.

254TECHNICAL SPECIFICATIONS
Tighten the lug nuts/bolts in a star pattern until each nut/
bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it halfway).

Torque Patterns

After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly tightened.
FUEL REQUIREMENTS
While operating on gasoline with the required octane
number, 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 a dealer
immediately. Use of gasoline with a lower than recommended octane number 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
considering service for the vehicle.
2.0L ENGINE
This engine is designed to meet all emission
requirements, and provide satisfactory fuel
economy and performance, when using
unleaded regular gasoline having an octane
rating of 87, as specified by the (R+M)/2 method. The use
of 91 or higher octane premium gasoline will allow these
engines to operate to optimal performance. This increase
in performance is most noticeable in hot weather or under
heavy load conditions, such as while towing.
2.4L ENGINE
This engine is designed to meet all emission
regulations and provide optimum fuel economy
and performance when using unleaded regular
gasoline having a posted octane number of 87
as specified by the (R+M)/2 method. The use of higher
octane premium gasoline is not required, as it will not
provide any benefit over regular gasoline in these engines.
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 specifically blended to reduce vehicle emissions
and improve air quality.
The use of reformulated gasoline is recommended.
Properly 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
oxygenates such as ethanol.
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 the New Vehicle Limited Warranty.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.
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
illuminate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than
15% ethanol (E-15).
