Delayed Locking
If your vehicle is a crew cab, it may be equipped with
this feature. When locking the doors with the power lock
switch or the keyless entry transmitter and a door is
open, the doors will not lock until ve seconds after the
last door is closed. You will hear three chimes to
signal that the delayed locking feature is in use.
Pressing the power lock switch or the lock button on the
keyless entry transmitter twice will override the delayed
locking feature and immediately lock all the doors.
You can turn the delayed locking feature off or back on
again by doing the following:
1. Press and hold the power door lock switch in the
lock position.
2. Press unlock twice on the remote keyless entry
transmitter.
This feature will not operate if the key is in the ignition.
You can also program this feature using the DIC.
SeeDIC Vehicle Customization on page 3-63.
Programmable Automatic Door
Locks
Your vehicle may be equipped with an automatic
lock/unlock feature which enables you to program your
vehicle’s power door locks. You can program this
feature through the Driver Information Center (DIC), or
by the following method. SeeDIC Vehicle Customization
on page 3-63.
Programmable Locking Feature
Following are the two available programming options:
Mode 1:All doors lock when the transmission is shifted
into gear. This is the mode that is pre-programmed in
the factory for your vehicle for automatic transmission
vehicles.
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h). This is the mode that is
pre-programmed in the factory for manual transmission
vehicles.
2-10

The following instructions tell you how to change the
automatic door lock mode (automatic transmission only).
Choose one of the two programming options listed
above before entering the program mode. To enter the
program mode, do the following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.
2. Turn the key to RUN then back to LOCK twice.
Then, with the key in LOCK, release the turn
signal/multifunction lever. Once you do this, the
doors will lock and unlock, the horn will chirp twice,
and a 30-second timer will begin. You are now
ready to program the automatic door lock feature.
3. Press the door lock switch once. You will hear either
one or two chimes. The number of chimes tells you
which lock mode is currently selected. Continue
to press the door lock switch until the number
of chimes that you hear matches the number of the
mode that you want. If you take longer than
30 seconds, the locks will automatically lock and
unlock and the horn will chirp twice to indicate that
you have left the program mode. If this occurs,
you can repeat the procedure beginning with Step 1
to re-enter the programming mode.You can exit the program mode any time by turning the
ignition to RUN (the doors will automatically lock and
unlock and the horn will chirp twice to indicate that you
are leaving the program mode). If the lock/unlock
switches are not pressed while in the programming
mode, the current automatic settings will not be
modied.
See your dealer for more information.
Programmable Unlocking Feature
The following is the list of available programming
options:
Mode 1:Driver’s door unlocks when the transmission is
shifted into PARK (P), for automatic transmission
vehicles only.
Mode 2:All doors unlock when the transmission is
shifted into PARK (P), for automatic transmission
vehicles only. This is the mode that is pre-programmed
in the factory for your vehicle.
Mode 3:All doors unlock when the key is removed
from the ignition. This is the mode that is
pre-programmed in the factory for manual transmission
vehicles.
Mode 4:No automatic door unlock.
2-11

Ignition Positions
With the key in the ignition switch, you can turn it to
four different positions.
Notice:If your key seems stuck in LOCK and you
cannot turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with your
hand. Using a tool to force it could break the key or
the ignition switch. If none of these works, then your
vehicle needs service.A (Lock):This position locks your ignition when the key
is removed. The steering locks when equipped with a
manual transmission. It is a theft-deterrent feature. You
will only be able to remove your key when the ignition is
turned to LOCK.
B (Accessory):This position allows you to use things
like the radio, power windows and the windshield
wipers when the engine is off.
{CAUTION:
On manual transmission vehicles, turning the
key to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to ACCESSORY. Do not
press the key release button while the vehicle
is moving.
C (Run):This is the position for driving.
D (Start):This position starts your engine.
2-22

Key Release Button
(Manual Transmission)
The ignition key cannot be
removed from the ignition
of manual transmission
vehicles unless the key
release button is used.
To remove the key on manual transmission vehicles, turn
the key to ACCESSORY, then press the button and turn
the key to LOCK. Do not hold the button in while turning
the key to ACCESSORY. Pull the key straight out.
Retained Accessory Power (RAP)
If the vehicle has Retained Accessory Power (RAP),
certain features will continue to operate for up to
10 minutes after the ignition key is turned to LOCK
unless a door is opened.
Starting Your Engine
Your vehicle is equipped with Starter Motor Control.
This feature assists in starting the engine and protects
the electrical system. This feature may cause the
engine to crank even after the ignition key is not in
START.
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only. If you have a diesel
engine refer to the diesel supplement for the starting
procedure.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
2-23

Manual Transmission
The gear selector should be in neutral and the parking
brake engaged. Hold the clutch pedal to the oor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a safety
feature.
Starting Your V8 Engine
1. With your foot off the accelerator pedal, turn the
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 disengage the starter
motor, cause your battery to be drained much
sooner, and add excessive heat that can damage
your starter motor. Try not to hold the key in START
for longer than 15 seconds and wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it does not start within 10 seconds, push the
accelerator pedal all the way to the oor, while
you hold the ignition key in START. When
the engine starts, let go of the key and let up on the
accelerator pedal. Wait about 15 seconds between
each try.When starting your engine in very cold weather
(below 0°F or−18°C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of
the key.
2. If your engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briey but then stops again, do the
same thing, but this time keep the pedal down
for ve or six seconds. This clears the extra
gasoline from the engine.
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 do not, your engine
might not perform properly.
2-24

If you manually select SECOND (2) in a light duty
automatic transmission, the transmission will drive in
second gear. You may use this feature for reducing the
speed of the rear wheels when you are trying to start
your vehicle from a stop on slippery road surfaces.
FIRST (1):This position gives you even more power
(but lower fuel economy) than SECOND (2). You
can use it on very steep hills, or in deep snow or mud.
If the selector lever is put in FIRST (1) while the
vehicle is moving forward, the transmission will not shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
On cold days, approximately 32°F (0°C) or colder, your
transmission is designed to shift differently. The
transmission uses a warm-up mode shift schedule until
the engine reaches normal operating temperature.
While the transmission is in warm-up mode it is normal
for transmission upshifts to be delayed or held longer.
This feature improves heater performance by giving
quicker vehicle warm-ups.Tow/Haul Mode
If your vehicle has an automatic transmission, it may be
equipped with a Tow/Haul mode. The selector button
is located on the end of the column shift lever. You can
use this feature to assist when towing or hauling a
heavy load. Turn Tow/Haul on and off by pressing the
button until the Tow/Haul indicator light illuminates
on the instrument panel.
