to choose between short or long horn chirp sounds when
the remote keyless entry transmitter is used.
Programmable Modes
Mode 1: SHORT
-- Short Chirp
Mode 2: LONG
-- Long Chirp
Before your vehicle was shipped from the factory, it was
programmed to Mode 1. The mode to which your
vehicle was programmed may have been changed since
it left the factory. To determine the mode to which your
vehicle is programmed or to program your vehicle to a
different mode, do the following:1. Scroll, using the SEEK up or down arrows, until
CHIRP appears on the display.
2. Press the PREV or NEXT button to enter the submenu.
The current selection will have an asterisk (*) next to
it. If you do not wish to change the current mode, you
can either exit the programming mode by following the
directions later in this section or program the next
feature available on your vehicle.
3. Scroll, using the PREV or NEXT buttons, through
the modes to change the current mode.
4. With your preference displayed, press the DISP
button to select. A chime will be heard to verify the
new setting. The new selection will be displayed
with an asterisk (*) for one second.
The mode you selected is now set. You can either exit
the programming mode by following the instructions
later in this section or program the next feature available
on your vehicle.

2. If the engine doesn't start in 10 seconds, push the
accelerator pedal about one
-quarter of the way down
while you turn the key to START. Do this until the
engine starts. As soon as it does, let go of the key.
3. If your engine still won't start (or starts but then stops),
it could be flooded with too much gasoline. Try
pushing your accelerator pedal all the way to the floor
and holding it there as you hold the key in START for
a maximum of 15 seconds. This clears the extra
gasoline from the engine. If the engine still won't start
or starts briefly but then stops again, repeat Step 1 or 2,
depending on temperature. When the engine starts,
release the key and the accelerator pedal.
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.
Starting Your 3800 Series II V6 Engine
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start within 10 seconds, hold your key
in START for about 10 seconds at a time until
your engine starts. Wait about 15 seconds between
each try.

3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing.
This time keep the pedal down for five or
six seconds to clear the extra gasoline from the
engine. After waiting about 15 seconds, repeat the
normal starting procedure.
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.
Engine Coolant Heater (Option)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm

the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle. At temperatures
above 32
F (0
C), use of the coolant heater is
not required.

2-56 Delayed Headlamp Illumination
Delayed headlamp illumination provides a period of
exterior lighting as you leave the area. The feature is

will glow in the button to let you know that the fog
lamps are on. Press the Fog button again to turn the fog
lamps off.
Your parking lamps must be on or your fog lamps won't
