Delayed Locking
This feature allows the driver to delay the actual locking
of the doors. When the driver power door lock switch is
pressed with the key removed from the ignition, and the
driver door open, a chime will sound three times to signal
that the delayed locking system is active. When all doors
have been closed, the doors will lock automatically after
several seconds. If any door is opened before this, the
timer will reset itself once all the doors have been
closed again.
Pressing the driver or passenger power door lock switch
again or the remote keyless entry transmitter button
will override this feature.
Personal Choice Programming
The delayed locking feature can be turned on or off,
using the Driver Information Center (DIC) to program
this feature. See “DELAY DOOR LOCK” underDIC
Vehicle Customization on page 3-66.
Programmable Automatic Door
Locks
Your vehicle is programmed so that, when the doors are
closed, the ignition is on, and the shift lever is moved
out of PARK (P), all the doors will lock. The doors
will unlock every time you stop the vehicle and move
the shift lever into PARK (P).
If someone needs to get out while your vehicle is not in
PARK (P), have the person use the manual lock knob or
power door lock switch. When the door is closed again, it
will not lock automatically. Use the manual lock knob or
power door lock switch to lock the door.
If your vehicle has a Driver Information Center (DIC),
you can choose various lock and unlock settings.

When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
will stay on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means there is a brake problem.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If the light comes on while driving, pull off the road and
stop carefully. The pedal can be harder to push, or the
pedal could go closer to the oor. It could take longer to
stop. Try turning off and restarting the vehicle one or two
times, if the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-23.
Antilock Brake System (ABS)
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally
the indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the
light comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-38.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-56for
all brake related DIC messages.
3-39

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located
below the speedometer in the instrument panel cluster.
The DIC buttons are located on the instrument panel,
to the left of the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was last
displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. The bottom line of the DIC shows the shift
lever position indicator. SeeAutomatic Transmission
Operation on page 2-25for more information.
If your vehicle’s DIC has these features, the compass
direction and the outside air temperature may also
display on the DIC when viewing the trip and fuel
information. The compass direction appears on the
top right corner of the DIC display. The outside air
temperature automatically appears in the bottom right
corner of the DIC display. If there is a problem with
the system that controls the temperature display,
the numbers will be replaced with dashes. If this occurs,
have the vehicle serviced by your dealer/retailer.
The DIC also allows some features to be customized.
SeeDIC Vehicle Customization on page 3-66for
more information.
DIC Operation and Displays

on the DIC.
Trip/Fuel Menu Items
3
(Trip/Fuel):Press this button to scroll through the
following menu items:
Odometer
Press the trip/fuel button until ODOMETER displays.
This display shows the distance the vehicle has
been driven in either miles (mi) or kilometers (km).
Trip A and Trip B
Press the trip/fuel button until TRIP A or TRIP B
displays. This display shows the current distance traveled
in either miles (mi) or kilometers (km) since the last reset
for each trip odometer. Both trip odometers can be used
at the same time.Each trip odometer can be reset to zero separately by
pressing the set/reset button while the desired trip
odometer is displayed.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles (kilometers) driven since the ignition was
last turned on. This can be used if the trip odometer is not
reset at the beginning of the trip.
To use the retro-active reset feature, press and
hold the set/reset button for at least four seconds.
The trip odometer will display the number of miles (mi)
or kilometers (km) driven since the ignition was last
turned on and the vehicle was moving. Once the vehicle
begins moving, the trip odometer will accumulate
mileage. For example, if the vehicle was driven 5 miles
(8 km) before it is started again, and then the retro-active
reset feature is activated, the display will show 5 miles
(8 km). As the vehicle begins moving, the display will then
increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the display
will show the number of miles (mi) or kilometers (km) that
were driven during the last ignition cycle.
3-50

Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of remaining
miles (mi) or kilometers (km) the vehicle can be driven
without refueling.
The fuel range estimate is based on an average of the
vehicle’s fuel economy over recent driving history and the
amount of fuel remaining in the fuel tank. This estimate
will change if driving conditions change. For example, if
driving in traffic and making frequent stops, this display
may read one number, but if the vehicle is driven on a
freeway, the number may change even though the same
amount of fuel is in the fuel tank. This is because different
driving conditions produce different fuel economies.
Generally, freeway driving produces better fuel economy
than city driving.
If your vehicle is low on fuel, the FUEL LEVEL LOW
message will be displayed. See “FUEL LEVEL LOW”
underDIC Warnings and Messages on page 3-56for
more information.
Average Economy
Press the trip/fuel button until AVG ECONOMY displays.
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number of mpg
(L/100 km) recorded since the last time this menu item
was reset. To reset AVG ECONOMY, press and hold the
set/reset button. The display will return to zero.
Instantaneous Economy
Press the trip/fuel button until INST ECONOMY
displays. This display shows the current fuel economy
at a particular moment and will change frequently as
driving conditions change. This display shows the
instantaneous fuel economy in miles per gallon (mpg)
or liters per 100 kilometers (L/100 km). Unlike average
economy, this screen cannot be reset.
Average Speed
Press the trip/fuel button until AVERAGE SPEED
displays. This display shows the average speed of the
vehicle in miles per hour (mph) or kilometers per hour
(km/h). This average is calculated based on the various
vehicle speeds recorded since the last reset of this value.
To reset the value, press and hold the set/reset button.
The display will return to zero.
Blank Display
This display shows no information.
