To remove the ignition key on models with a manual
transmission, depress and hold the key release button,
turn the ignition key to LOCK, and remove the key.Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition,
sounds a signal to remind you to remove the key.
CAUTION!
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
SENTRY KEY IMMOBILIZER SYSTEM — IF
EQUIPPED
The Sentry Key Immobilizer System (SKIS) prevents
unauthorized operation of the vehicle by disabling the
engine. The system will shut the engine down after 2
seconds of running if an invalid key is used to start the
vehicle. This system utilizes ignition keys which have an
electronic chip (transponder) embedded into them. Only

14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Ignoring the “Airbag Warning Light” in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and in the
instrument panel. When the ACM detects a collision
requiring the airbags, it signals the inflator units. A
large quantity of nontoxic gas is generated to inflate
the airbags. The airbag covers separate and fold out of
the way as the bags inflate to full size. The bags fully
inflate in about 50 milliseconds. This is about half of
the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver andfront passenger. The driver’s front airbag gas is vented
through the airbag material towards the instrument
panel. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•TheKnee Impact Bolstershelp protect the knees and
position the driver and front passenger’s for the best
interaction with the front airbag.
If A Deployment Occurs
The airbag system is designed to deploy when the impact
sensors detect a moderate-to-severe frontal collision, to
help restrain the driver and front passenger, and then to
immediately deflate.
NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Exhaust Gas
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 the safety tips below.
•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
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with 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 conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
•On hardtop models, keep the tailgate window closed
when driving your vehicle. On fabric top models, do
not drive with the rear window curtain up unless theside curtains are also open. This will prevent carbon
monoxide and other poisonous exhaust gases from
entering the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a indicator check when the ignition switch is
first turned on. If the indicator is not lit during starting,

Compass Calibration
Automatic Calibration
Once calibrated, the compass has the ability to self-
correct for changes in magnetic field to keep the compass
accurate. This is referred to as Automatic Calibration. If
magnetic field changes are too great, the compass will
enter CAL mode on it’s own and manual calibration will
be required. To recalibrate the compass, drive the vehicle
at less than 5 mph (8 km/h) through up to 1
12360° turns
in an area free from large metal objects or power lines.
When the compass has been calibrated, the CAL symbol
will turn off and the compass will function normally.
When the vehicle is new, the compass should initially be
verified for correct compass variance (refer to Compass
Variation Adjustment) and calibrated manually (refer to
Manual Calibration). This will ensure correct initial cali-
bration and eliminate initial erroneous compass head-
ings.
Manual Calibration
If the compass appears erratic and CAL does not appear,
you must manually put the compass into the calibration
mode. To ensure proper compass calibration, make sure
the compass variance is properly set before manually
calibrating the compass (refer to Compass Variation
Adjustment).
To put the compass into calibration mode: Turn the
ignition to the ON position. Press and hold the center
button for more than 6 seconds until CAL (calibration
mode) appears in the display. To change the display
between VAR (compass variance) and CAL (compass
calibration) modes. Release the button to invoke manual
calibration mode. To recalibrate the compass, drive the
vehicle at less than 5 mph (8 km/h) through up to CAL
should display for a complete 1
12360° turns in an area
free from large metal objects or power lines. When the
compass has been calibrated, the CAL symbol will turn
off and the compass will function normally.

Rear Window Wiper/Washer
To utilize the rear wiper, press the switch to the
first detent. To activate the rear washer, depress the
switch to the second detent. The washer will
continue to spray as long as the switch is held. The switch
will return to the wiper mode when released. To turn the
rear wiper off, lift the bottom of the switch.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
