2-5 Central Door Unlocking System
Your vehicle will have this feature if it is equipped with
the theft
-deterrent system. When unlocking either front
door, you can unlock the other doors by holding the key
in the turned position for a few seconds or by quickly
turning the door key twice in the lock cylinder.
Power Door Locks
Press the power door lock
button to lock or unlock all
the doors at once. The rear
power door locks provide a
lock only function as a
convenience feature. For
safety reasons, they will not
unlock the doors.
Automatic Door Locks
Close your doors and turn on the ignition. Every time
you move the shift lever out of PARK (P), all of the
doors will lock. The doors will unlock every time you
stop the vehicle and move the shift lever back into
PARK (P). If someone needs to get out while your
vehicle is not in PARK (P), have that person use the
manual or power lock. When the door is closed again, it
will not lock automatically. Use the manual or power
lock to lock the door again. If you need to lock the doors
before shifting out of PARK (P), use the manual or
power lock button to lock the doors.
Programmable Automatic Door Locks
(If Equipped)
With the ignition in RUN, the door locks can be
programmed through prompts displayed by the Driver
Information Center (DIC). These prompts allow the
driver to choose various lock settings. For programming
information, see ªMemory and Personalization
Featuresº in the Index.

PASS-Key
II
Your vehicle is equipped
with the PASS
-Key II
theft
-deterrent system.
PASS
-Key II is a passive
system. The system is
armed when the key is
removed from the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that is read by the system in your vehicle. If the key
resistor matches the code stored in the vehicle system,
the vehicle's fuel and starting systems will be enabled. If
an incorrect key is used, the vehicle's fuel and starting
systems are disabled for three minutes. Additional
attempts during this lockout period will not start the car,
even with the correct key.If the engine does not start and the STARTING
DISABLED REMOVE KEY message is displayed in
the Driver Information Center, your key should be
checked for damage. Starting may be attempted with an
undamaged key immediately. See your dealer or a
locksmith for key service.
If the STARTING DISABLED REMOVE KEY and
WAIT 3 MINUTES messages are displayed, the key
should be cleaned. After three minutes, try again. A
START CAR message will appear at this time. If the
engine still does not start, wait three minutes and try a
duplicate key. At this time, fuses should be checked (see
ªFuses and Circuit Breakersº in the Index). If the engine
does not start with the duplicate key, your vehicle needs
service. See your dealer for service.
If the THEFT SYSTEM PROBLEM, CAR MAY NOT
START message is displayed during vehicle operation, a
fault has been detected in the system. This means the
PASS
-Key II system is disabled and is not protecting
the vehicle. The vehicle usually restarts. See your dealer
for service.
If an ignition key is lost or damaged, see your dealer or
a locksmith to have a new key made.

Turn Signal/Multifunction Lever
Turn and Lane Change Signals
To signal a turn, move the lever all the way up or
down. The lever returns automatically when the turn
is complete.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it's released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers won't see the turn signal.Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs if the
arrow fails to work when signaling a turn.
Headlamp High/Low Beam
Pull the turn signal lever all the way toward you and
then release it to change the headlamps from low beam
to high or from high beam to low.
This light on the instrument
panel will be on, indicating
high
-beam usage.
Flash-To-Pass
This lets you use the high-beam headlamps to signal the
driver in front of you that you want to pass.
Pull the turn signal lever toward you to use. When you do:

If the headlamps are either off or in the DRL mode,
the high
-beam headlamps will turn on. They'll stay
on as long as you hold the lever there. Release the
lever to turn them off.

2-39 Windshield Washer
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
At the top of the turn signal/multifunction lever there is
a paddle with the word PUSH on it. To spray washer
fluid on the windshield, press and release this paddle.
The wipers will clear the windshield and either stop or
return to your preset speed. For more washer cycles,
press and hold the paddle.
LOW WASHER FLUID will be displayed on the Driver
Information Center (DIC) when the washer fluid reaches
a low level.
Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can help on long trips. Cruise
control does not work at speeds below 25 mph
(40 km/h).
Cruise control shuts off when you apply your brakes.

yellowblue
2-40
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. (See ªTraction
Control Systemº in the Index.) When road conditions
allow you to safely use it again, you may turn the cruise
control back on.Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use it.
1. Move the cruise control switch to ON.
2. Accelerate to the speed you want.
3. Press the SET CRUISE button at the end of the lever
and release it. The CRUISE ENGAGED message
will display on the Driver Information Center (DIC).
4. Remove your foot from the accelerator pedal.
Resuming a Set Speed
Setting the cruise control at a desired speed and then
applying the brake will end the cruise function.

2-41
Once you're going about 25 mph (40 km/h) or more,
you can move the cruise control switch from ON to
R/A (Resume/Accelerate) briefly to reset. This returns
you to your desired preset speed. Also note that the
Driver Information Center (DIC) will display the
CRUISE ENGAGED message again.
Remember, if you hold the switch at R/A longer than
half a second, the vehicle will accelerate until you
release the switch or apply the brake. So unless you
want to go faster, don't hold the switch at R/A.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed.
Push the button at the end of the lever and then
release the button and the accelerator pedal. You'll
now cruise at the higher speed.

Move the cruise switch from ON to R/A. Hold it there
until you reach a desired speed and then release the
switch. (To increase your speed in very small amounts,
move the switch to R/A. Each time you do this, your
vehicle will go about 1 mph (1.6 km/h) faster.)
The accelerate feature will only work after you have
set the cruise control speed by pushing the SET
CRUISE button.Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Push in the button at the end of the lever until you
reach a desired lower speed, then release it. A
CRUISE ENGAGED message will then display in
the Driver Information Center (DIC).

To slow down in very small amounts, push the
button briefly. Each time you do this, you'll go
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.

When the Twilight Sentinel switch is on and it's dark
enough outside, the low
-beam headlamps (at reduced
intensity) will turn off and normal low
-beam headlamp
operation will occur. When the Twilight Sentinel switch
is on and it's bright enough outside, the regular lamps
will go off, and the low
-beam headlamps at reduced
brightness will take over for the DRL.
If it's dark enough outside and the Twilight Sentinel
control is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended even though the DRL
are still illuminated (it's become dark enough outside to
require the headlamps and/or other exterior lamps).
Turning on the Twilight Sentinel, the headlamp switch
or the fog lamp switch will remove the HEADLAMPS
SUGGESTED message.
To idle your vehicle with the DRL off, turn off the
Twilight Sentinel and shift the transaxle into PARK (P).
Placing your vehicle in PARK (P) disables the DRL.
The DRL will stay off until you shift out of PARK (P).
To drive your vehicle with the DRL off, turn off the
Twilight Sentinel and manually turn on the parking lamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps (DeVille Concours Only)
Use the fog lamps for better
vision in foggy or misty
conditions. When you press
the fog lamp button, a small
indicator light will tell you
that the fog lamps and the
parking lamps are on. Press
the button again to turn
them off.
If you turn on the high
-beam headlamps, the fog lamps
will turn off. They'll turn back on again when you
switch to low
-beam headlamps.
When the Twilight Sentinel is on and the fog lamp
switch is activated, the fog lamps will remain on as well
as the headlamps and parking lamps.

2-45 Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn. They
provide more light for cornering.
Twilight Sentinel

This control is next to the
headlamp knob. It
automatically switches the
lamps on and off by sensing
how dark it is outside.
To operate the Twilight Sentinel, leave the lamp knob
off and move the TWILIGHT control to any position
but OFF.If you move the control all the way to the right, the
lamps will remain on for approximately three minutes
after the ignition has been turned to OFF or LOCK. If
you move the control so it is just on, the lamps will go
off quickly when you turn the ignition switch out of
RUN. You can adjust the delay time from only a few
seconds to three minutes.
If it's dark enough outside and the Twilight Sentinel
control is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended (it's become dark
enough outside to require the headlamps and/or other
exterior lamps). Turning on the Twilight Sentinel, the
headlamp switch or the fog lamp switch will remove the
HEADLAMPS SUGGESTED message.
