•Avoid excessive idling.
•Check the engine oil level at every fuel fill.
NOTE:A new engine will consume some oil during the
first few thousand miles (kilometers) of operation. This
should be considered as a normal part of the break-in and
not interpreted as a sign of difficulty.
SAFETY TIPS
Exhaust System
WARNING!
Exhaust gases contain carbon monoxide, an ex-
tremely toxic gas that by itself is colorless and
odorless. To avoid inhaling these gases, the following
precautions should be observed:
(Continued)
WARNING! (Continued)
•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.
•It may be necessary to sit in a parked vehicle with
the engine running for more than a short period. If
so, adjust your climate control system to force
outside air into the vehicle. Set the blower at high
speed and the controls in any position except OFF
or RECIRC.
•The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Be aware of changes in the sound of the exhaust system,
exhaust fumes detected inside the vehicle, or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and side wall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check Turn Signal and High
Beam Indicator Lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, water, oil, or other fluid leaks. Also, if gasoline
fumes are present, the cause should be corrected
immediately.

Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
remains on through several of your typical driving
cycles. In most situations, the vehicle will drive normally
and will not require towing.
The MIL flashes to alert you to serious conditions that
could lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any state emissions
tests can be performed.
Turn Signal Indicators
The left or right arrow will flash in unison with the
corresponding front and rear turn signals when the
TURN SIGNAL switch is operated.
Hazard Indicators
Both turn signal arrows will flash in unison with the
front and rear turn signals when the HAZARD
WARNING button is operated.
NOTE:Leaving the hazard flashers on for extended
periods will wear down the battery.
Airbag Warning Light
This light will turn on for six to eight seconds
as a bulb check when the ignition switch is first
turned on. If the light does not turn on during
starting, remains on after starting, or turns on
while driving, have the system checked immediately by
an authorized dealer.

•If the light turns on steady while the engine is running,
safely bring the vehicle to a complete stop as soon as
possible, cycle the ignition key, and then restart the
engine. The light should turn off. However, if the light
remains on steady, see your authorized dealer for
service as soon as possible.
•If the light is flashing when the engine is running,
immediate service is required. If this occurs, you may
experience reduced vehicle performance, an elevated/
rough idle or engine stall, and your vehicle may
require towing.
Low Tire Pressure Telltale / TPMS Malfunction
Indicator
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has tires ofa different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

This gauge does not indicate the amount of oil in the
engine. The engine oil level must be checked under the
hood. Check the level often during severe usage.
Oil Pressure Warning Light
The red Oil Pressure Warning Light is located in
the Oil Pressure Gauge. It will turn on to indicate
low engine oil pressure. The light should turn on briefly
as a bulb check when the engine is first started. If the
light remains on or turns on while driving, safely bring
the vehicle to a complete stop and turn off the engine. DO
NOT operate the vehicle until the cause is corrected.
NOTE:This light does not indicate how much oil is in
the engine. The engine oil level must be checked using
the procedure shown in section 7.
Fuel Gauge
This gauge shows the amount of fuel in the gas
tank. The reaction time of the gauge has been
slowed to avoid needle fluctuation during pe-
riods of high G force cornering.
Voltage Gauge
This gauge shows the electrical system voltage.
The normal operating voltage is from 12 to
14 Volts with the engine running. If the pointer
remains at either the high or low ends of the
scale, the electrical system should be serviced.
Charge System Light
The red Charge System Light is located in the
Voltage Gauge. It will turn on when there is a
charging system malfunction or a possible accessory
drive belt failure.

NOTE:There is a varying temperature differential be-
tween the upper and lower outlets for added comfort.
The warmer air goes to the floor outlets. This feature
provides improved comfort during sunny but cool con-
ditions.
•Floor
Air is directed through the floor outlets with a
lesser amount through the defrost outlets.
•Defrost/Floor
Air is directed through the windshield defrost and
the floor outlets. This setting works best in cold or
snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield.
•Defrost
Air is directed through the windshield defrost
outlet. Use this mode with maximum fan and
temperature settings for best windshield defrosting.NOTE:The air conditioning compressor operates in this
mode. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, leave in the Defrost
mode only when necessary.
Air Conditioning Control
With the fan control in the ON position, push the
A/C button to turn on the air conditioning com-
pressor. An indicator light above the button shows
that the Air Conditioning compressor is on. Conditioned
air is now directed through the outlets selected. Pushing
the button a second time turns the compressor OFF.
Slight changes in engine speed or power may be noticed
when the compressor is on. This is a normal occurrence
since the compressor will cycle on and off to maintain
comfort and increase fuel economy.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects.
