How to Use This Manual
Many people read their owner's manual from beginning
to end when they ®rst receive their new vehicle. If
you do this, it will help you learn about the features and
controls for your vehicle. In this manual, you'll ®nd
that pictures and words work together to explain things.
Index
A good place to look for what you need is the Index in
back of the manual. It's an alphabetical list of what's

CAUTION: (Continued)
this way, in a crash the child might slide under
the belt. The belt's force would then be applied
right on the child's abdomen. That could cause
serious or fatal injuries.
The lap portion of the belt should be worn low and snug
on the hips, just touching the child's thighs. This
applies belt force to the child's pelvic bones in a crash.
Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle's
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it's probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
1. Insert a coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter, positive (+)
side up. Use a battery, type CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water won't get in.
5. Test the transmitter.

When starting your engine in very cold weather (below
0ÉF or-18ÉC), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of
the key.
2. If your engine still won't start (or starts but then
stops), it could be ¯ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
¯oor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the
vehicle starts brie¯y but then stops again, do the
same thing, but this time keep the pedal down
for ®ve or six seconds. This clears the extra
gasoline from the engine.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you don't, your engine
might not perform properly.
Starter Interlock Feature
For your convenience and to avoid damage to your
starter, your vehicle is equipped with a starter interlock
feature. This feature will not allow you to crank the
engine while the vehicle is already running.
Racing or Other Competitive Driving
See your warranty book before using your vehicle
for racing or other competitive driving.
Notice:If you use your vehicle for racing or other
competitive driving, your engine may use more
oil than it would with normal use. Low oil levels can
damage the engine. Be sure to check the oil level
often during racing or other competitive driving and
keep the level at or near 1 quart (1 L) above the
upper mark that shows the proper operating range
on the engine oil dipstick. For information on
how to add oil, see ªEngine Oilº in the Index. After
the competitive driving, remove excess oil so
that the level on the dipstick is not above the upper
mark that shows the proper operating range.

Mirrors
Manual Rearview Mirror
An inside rearview mirror is attached above the
windshield. The mirror pivots so that you can adjust it.
You can adjust the mirror for day or night driving.
Pull the tab for night driving to reduce glare. Push the
tab forward for daytime driving.
Automatic Dimming Rearview Mirror
Your vehicle may have an automatic dimming rearview
mirror with map lamps.
This mirror automatically changes to reduce glare from
headlamps behind you. A time delay feature prevents
rapid changing from the day to night positions while
driving under lights and through traffic.The mirror includes two map lamps and an automatic
dimming function. There is also an interior console ¯ood
lamp located underneath the rearview mirror which
remains on at all times.
IO (On/Off):The automatic dimming feature is turned
on or off by pressing this button located on the
lower part of the mirror. Press and hold the button for
up to three seconds to turn this feature on or off.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror housing.

After a ®ve-second display of the current settings, only
the word AUTO and the outside temperature will be
shown on the digital display unless the system is set to
full cold 60ÉF (16ÉC) or full hot 90ÉF (32ÉC), then the
word AUTO will not display. The system will operate to
achieve your comfort set temperature as quickly as
possible. The AUTO control system works best with the
windows up and the removable roof installed or the
convertible top up.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 60ÉF (16ÉC) or full hot 90ÉF (32ÉC).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the coldest or
warmest temperature setting, the system will remain
in manual mode at that temperature and it will not
go into automatic mode.
In cold weather, the system will start at reduced fan
speeds at avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the ¯oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see ªSolar Sensorº later
in this section.
Manual Operation
OFF:Press this button to turn off the climate control
system. This is the only setting that fully shuts off
the fan. The digital display will show only the outside
temperature. You can still adjust the driver's set
temperature, the passenger temperature offset and the
air intake mode while in OFF.
MODE:Press this button to manually lock in the current
air delivery setting and to stop the automatic mode
control. Pressing the MODE button will delete AUTO
from the digital display and the mode graphics will
be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed
to return to the automatic mode selection.

You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select recirculate mode.
3. Select the A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.Sensors
The solar sensor on your vehicle monitors the solar
radiation and uses the information to maintain the
selected temperature when operating in AUTO mode by
initiating needed adjustments to the temperature, the
fan speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing
the sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on
the top right side of the instrument panel near the
windshield or the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
·The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.
·The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
