2-19 Passive Arming
If the ignition was just turned off and a door was
opened, the system will arm six seconds after both doors
are closed, whether or not you lock them. In all other
cases, the system will wait 30 seconds after both doors
are closed before arming, allowing you time to get into
the vehicle and put the key in the ignition. The parking
lamps will flash when the system arms.
The vehicle is shipped from the factory with this feature
turned off. To turn this feature on, see ªFeature
Customizationº in the Index.
Disarming the System
There are two ways to disarm the system:
Press the UNLOCK button on the remote keyless entry
transmitter. If the horn chirps two or three times when
you unlock the vehicle, the alarm sounded in your
absence. Two chirps means that the shock sensor was
set off and three chirps means that a door or the hatch
was opened.
Turn the ignition key to RUN.
For more information on customizing the features
mentioned here, see ªFeature Customizationº in 
the Index.
PASS-Key II
Your vehicle is equipped
with the PASS
-Key II
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key II is a passive
theft
-deterrent system. 
It works when you insert 
or remove the key from 
the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS
-Key II system senses that someone is
using the wrong key, it shuts down the vehicle's starter and
fuel systems. For about three minutes, the starter won't
work and fuel won't go to the engine. If someone tries to
start your vehicle again or uses another key during this
time, the vehicle will not start. This discourages someone
from randomly trying different keys with different resistor
pellets in an attempt to make a match.
The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start.

Engine Coolant Heater (Canada Only)
In very cold weather, 0F (-18C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is attached to the outside of the underhood
fuse box.3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine parts. If you don't, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

2-37
AUTOMATIC OVERDRIVE (): This position is 
for normal driving. If you need more power for passing,
and you're:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
DRIVE (D): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE ().
Here are some times you might choose DRIVE (D)
instead of AUTOMATIC OVERDRIVE ():
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
If you have a 5.7L V8 engine and manually 
select SECOND (2) when you start the vehicle, the
transmission will drive (and stay) in second gear. You
may use this feature for reducing torque to the rear
wheels when you are trying to start your vehicle from a
stop on slippery road surfaces, or for preventing the
transmission from downshifting into FIRST (1) in
situations where a downshift would be undesirable.
NOTICE:
Don't drive in SECOND (2) for more than 
25 miles (40 km), or at speeds over 55 mph 
(90 km/h), or you can damage your transmission.
Use AUTOMATIC OVERDRIVE () or 
DRIVE (D) as much as possible.
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine. 
     
        
        Page 96 of 363

2-38
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
gearshift lever is put in FIRST (1) gear, the transmission
won't shift into first gear until the vehicle is going 
slow enough.
NOTICE:
If your rear wheels can't turn, don't try to drive.
This might happen if you were stuck in very deep
sand or mud or were up against a solid object.
You could damage your transmission.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into 
PARK (P) to hold your vehicle in position 
on a hill.
Maximum engine speed is limited to protect driveline
components from improper operation.
Second-Gear Start (V6 Automatic) 
(If Equipped)
Your vehicle may 
be equipped with a
Second
-Gear Start feature.
Press the Second
-Gear Start
(SGS) button located on the
instrument panel to provide
more traction when you are
starting on ice or other
slippery surfaces.
The light on the button will illuminate when
Second
-Gear Start (SGS) is selected. The transmission
will be in SECOND (2) gear when the vehicle begins to
move. After starting in SECOND (2), the vehicle will
upshift normally.
This feature is only for improved traction when the road
surface is slippery and is not intended for continuous
use. Turn the Second
-Gear Start (SGS) button off for
normal road conditions by pressing the button again.
The light on the button will go out. Whenever you start
your vehicle, the transmission is in the normal mode.

2-41 Shift Speeds
CAUTION:
If you skip a gear when you downshift, you could
lose control of your vehicle. You could injure
yourself or others. Don't shift down more than
one gear at a time when you downshift.
This chart shows when to shift to the next higher gear
for best fuel economy.If your speed drops below 20 mph (32 km/h), or if the
engine is not running smoothly, you should downshift to
the next lower gear. You may have to downshift two or
more gears to keep the engine running smoothly or for
good performance.
NOTICE:
If you skip more than one gear when you
downshift, or if you race the engine when you
downshift, you can damage the clutch 
or transmission.
Skip Shift Light (5.7L V8 Engine)
When the SKIP SHIFT light
is on, the gearshift lever
will let you shift from
FIRST (1) to FOURTH (4)
instead of shifting from
FIRST (1) to SECOND (2).
Once you are in FOURTH (4), you can press the clutch
again and shift into another gear.
