Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console
or glove box lamps are accidentally left on. If you leave
any of these lamps on, they will automatically time-out
after about 20 minutes. To reset it, all of the above
lamps must be turned off or the ignition key on.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If your vehicle is equipped with the Head-Up
Display (HUD), you can see some of the driver
information that appears on your instrument panel
cluster.The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. The HUD consists of the
following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Tachometer
Oil and Temperature Gages
Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle’s best performance level has
been reached to shift the transmission into the next
higher gear. The SHIFT light will display at an
engine speed of about 6,250 rpm, just prior
to reaching the engine fuel cut-off mode.

If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate control
system is in recirculation mode an indicator light
will come on. This mode prevents outside air from
entering your vehicle. It can be used to prevent outside
air and odors from entering your vehicle and to help
cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.
^(Air Conditioning Off):Press this button to turn
the air conditioning compressor off. Press AUTO
to return to automatic operation. When in AUTO, the air
conditioning compressor will come on automatically,
as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.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 press the AUTO
button and adjust the temperature to a cool, comfortable
setting. To achieve maximum cool down, do the
following:
1. Select the vent mode.
2. Select recirculation mode.
3. Select the A/C on.
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.

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the
vehicle is running. You will know how fast you are going, about how much fuel you have left and many other
things you will need to know to drive safely and economically. The instrument panel cluster indicator warning lights,
gages and DIC messages are explained on the following pages.

Speedometer and Odometer
Your speedometer lets you see your speed in either
miles per hour (mph) or kilometers per hour (km/h). For
more information see “Personal Options” underDIC
Vehicle Personalization on page 3-69.
To read the odometer with the ignition off, turn on the
parking lamps.
You may wonder what happens if your vehicle needs a
new odometer installed. The mileage total of the
new odometer will be set to the original miles
(kilometers) of the old odometer. See your dealer if the
odometer must be replaced in your vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Notice:Fuel will shut off at about 6600 rpm. If you
continue to drive your vehicle at the fuel shut off
rpm, you could damage your engine. Be sure
to operate your vehicle below the fuel shut off
rpm or reduce your rpm quickly when the fuel
shuts off.
Safety Belt Reminder Light
When the ignition is turned on, a chime will be provided
for several seconds to remind people to buckle their
safety belts. The driver safety belt light will also be
provided and stay on for several seconds, then it will ash
for several more. You should buckle your seat belt.
This chime and light will be
repeated if the driver
remains unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor the
light will be provided.

One-to-Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to turn off
this feature. This helps you get the best possible fuel
economy.
After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
Notice:Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
The engine coolant temperature is higher than
169°F (76°C),
you are going 15 to 19 mph (24 to 31 km/h) and
you are 21 percent throttle or less.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine. If
it does not come on then, have it xed so it will be
ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-30
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.

Tire Pressure Light
This light should come on
briey as you start the
engine. It will then come on
only when a at or low
tire pressure condition
exists.
SeeTire Pressure Monitor System on page 5-60for
more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The Check Engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
3-42

Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on briey, as a check to show
you it is working, as you start the engine. If the light
does not come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission control
system on your vehicle. Diagnosis and service may
be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If the light stops ashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the engine off, wait at least 10 seconds and
restart the engine. If the light remains on steady, see “If
the Light Is On Steady” following. If the light is still
ashing, follow the previous steps, and see your dealer
for service as soon as possible.
3-43

If the Light Is On Steady
You also may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling the Tank on page 5-7. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misring, hesitation
on acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to x any
mechanical or electrical problems that may have
developed.
