Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery, in case you accidentally leave the
interior lamps on. If you leave any interior lamps on while
the ignition is in LOCK or OFF, they will automatically turn
off after 10 minutes. The lamps will not come back on
again until you do one of the following:
Turn the ignition to RUN or ACCESSORY.
Turn the interior lamps thumbwheel all the way to the
right, then slightly back to the left.
Open a closed door, or close and reopen a door.
If your vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.
Switchbanks
There are two sets of switchbanks located in the front of
the vehicle. The switches will vary with the options
that are on your vehicle.
Instrument Panel Switchbank
The instrument panel switchbank is located in the
instrument panel below the comfort controls. This
switchbank may include the following:
Rear Fan Knob. SeeRear Climate Control System
(Without Entertainment System) on page 3-29or
Rear Climate Control System (With Entertainment
System) on page 3-32.
Rear Window Wiper/Washer. See “Rear Window
Wiper/Washer” underTurn Signal/Multifunction
Lever on page 3-8.
Traction Control Switches. SeeTraction Control
System (TCS) on page 4-10.
If your vehicle does not have some of these options,
there will be a blank.
If your vehicle is not equipped with the rear climate
control system, there will be a storage space in
this switchbank. The rubber mat can be removed for
cleaning. Snap the mat into place after cleaning.

Retro-Active Reset
Each of the two trip odometers has a feature called
retro-active reset. This feature can be used to set either
or both trip odometer(s) to the number of miles
(kilometers) driven since the ignition was last turned on.
This can be used if you forget to reset your trip odometer
at the beginning of a trip. To use the retro-active reset
feature, press and hold the trip/reset button for at least
three seconds. The trip odometer will then display the
number of miles (kilometers) driven since the ignition was
last turned on and you began driving. If you use the
retro-active reset feature after you have started the
vehicle, but before you begin moving, the display will
show the number of miles (kilometers) you drove during
the last ignition cycle. Once you begin driving, the trip
odometer will accumulate mileage. For example, if you
have driven 5.0 miles (8.0 km) since you started your
vehicle, and then activate the retro-active reset feature,
the display will show 5.0 miles (8.0 km). As you drive, the
display will then increase to 5.1 miles (8.2 km), 5.2 miles
(8.4 km), etc. Only the trip odometer that is displayed will
be affected by the retro-active reset so that both trip
odometers can be used separately.
Tachometer
Your vehicle may have a tachometer that displays the
engine speed in revolutions per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.

This gage shows the
engine coolant
temperature. If the gage
pointer moves into the red
area, your engine is
too hot!
It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.

Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems. Cluster with Tachometer

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 SERVICE ENGINE SOON or 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.
Notice:If you keep driving your vehicle with this
light on, after a while, 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,
transaxle, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire PerformanceCriteria (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, as a check to show you it is
working, when the ignition is on and the engine is
not running. 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.

Your fuel gage tells you about how much fuel you have
left when the ignition is on.
Here are four things that some owners ask about. All
these things are normal and do not indicate that
anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off before
the gage reads full.
It takes a little more or a little less fuel to ll up than
the gage reads. For example, the gage reads half
full, but it took more or less than half of the
tank’s capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate empty when the ignition
is turned off.
