2-29 Starting Your 5.7L V8 Engine
1. Without pushing 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 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, push the
accelerator pedal all the way to the floor, 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 to
help avoid draining your battery or damaging
your starter.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. When the
engine starts, let go of the key. Use the accelerator
pedal to maintain engine speed, if you have to, until
your engine has run for a while.
2. 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. When the engine
starts, let go of the key and accelerator. If the vehicle
starts briefly but then stops again, do the same thing,
but this time keep the pedal down for five or
six seconds. This clears the extra gasoline from
the engine.

2-30
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.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.
Engine Coolant Heater (Canada Only)
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
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.

2-31 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.

Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It's the best
position to use when you start your engine because your
vehicle can't move easily.
CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
See ªShifting Into PARK (P)º in the Index. If
you're pulling a trailer, see ªTowing a Trailerº in
the Index.

2-33
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You have to fully
apply your regular brakes before you can shift from
PARK (P) when the ignition key is in RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
lever
-- push the shift lever all the way into PARK (P)
and also release the shift lever button on floor shift
console models as you maintain brake application. Then
move the shift lever into the gear you wish. (Press the
shift lever button before moving the shift lever on floor
shift console models.) See ªShifting Out of PARK (P)º
in the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your
transmission. Shift to REVERSE (R) only
after your vehicle is stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission, see
ªStuck: In Sand, Mud, Ice or Snowº in the Index.
NEUTRAL (N): In this position, your engine doesn't
connect with the wheels. To restart when you're already
moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.

2-34
NOTICE:
Damage to your transmission caused by shifting
out of PARK (P) or NEUTRAL (N) with the
engine racing isn't covered by your warranty.
AUTOMATIC OVERDRIVE (D): 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.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

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.
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 (D) or
THIRD (3) 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.

2-35
FIRST (1): This position (if equipped) 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
gear, the transmission won't shift into FIRST (1) until
the vehicle is going slowly enough.
NOTICE:
If your rear wheels can't rotate, 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.
Manual Transmission Operation
5-Speed
This is your shift pattern
for your five
-speed
manual transmission.
Here's how to operate your transmission:
FIRST (1): Press the clutch and shift into FIRST (1).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
You can shift into FIRST (1) when you're going less
than 20 mph (32 km/h). If you've come to a complete
stop and it's hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch. Press the
clutch pedal back down. Then shift into FIRST (1).

2-36
SECOND (2): Press the clutch pedal to the floor as you
let up on the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
THIRD (3), FOURTH (4) and FIFTH (5): Shift into
THIRD (3), FOURTH (4) and FIFTH (5) the same way
you do for SECOND (2). Slowly let up on the clutch as
you press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and brake pedal, and shift into NEUTRAL.
NEUTRAL: Use this position when you start or idle
your engine.
REVERSE (R): To back up, press the clutch pedal and
shift into REVERSE (R). Let up on the clutch pedal
slowly while pressing the accelerator pedal.
NOTICE:
Shift to REVERSE (R) only after your vehicle is
stopped. Shifting to REVERSE (R) while your
vehicle is moving could damage your transmission.
Also use REVERSE (R), along with the parking brake,
for parking your vehicle.
6-Speed
This is your shift pattern
for you six
-speed
manual transmission.
Here's how to operate your transmission:
FIRST (1): Press the clutch pedal and shift into
FIRST (1). Then slowly let up on the clutch pedal as
you press the accelerator pedal.
You can shift into FIRST (1) when you're going less
than 20 mph (32 km/h). If you've come to a complete
stop and it's hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch. Press the
clutch pedal down. Then shift into FIRST (1).
SECOND (2): Press the clutch pedal as you let up on
the accelerator pedal and shift into SECOND (2). Then,
slowly let up on the clutch pedal as you press the
accelerator pedal.

2-37
THIRD (3), FOURTH (4), FIFTH (5) and
SIXTH (6): Shift into THIRD (3), FOURTH (4),
FIFTH (5) and SIXTH (6) gear the same way you do for
SECOND (2). Slowly let up on the clutch pedal as you
press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and brake pedal, and shift to NEUTRAL.
NEUTRAL: Use this position when you start or idle
your engine.
REVERSE (R): To back up, press the clutch pedal and
shift into REVERSE (R). Let up on the clutch pedal
slowly while pressing the accelerator pedal. If you shift
from SIXTH (6) into REVERSE (R), the shift lever
must be first placed in NEUTRAL position centered
between SECOND (2) and THIRD (3) prior to shifting
into REVERSE (R).
Your six
-speed manual transmission has a feature that
allows you to safely shift into REVERSE (R) while the
vehicle is rolling at less than 5 mph (8 km/h).
If you have turned your ignition off and want to park
your vehicle in REVERSE (R), you will have to move
the shift lever quickly to the right, then forward
into gear.
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.

2-38
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.This light helps you get the best possible fuel economy.
It will come on under these conditions:

The engine coolant temperature is greater than
170F (77C),

you are going 15 to 20 mph (24 to 32 km/h) and

you are at 35 percent throttle or less.
Follow the shift speeds listed below when the SKIP
SHIFT light is on.
Computer
-Aided Manual Transmission Shift Speeds

1st to 4th @ 15 mph (24 km/h)

4th to 5th @ 25 mph (40 km/h)*

5th to 6th @ 49 mph (64 km/h)**
Each time you come to a stop, the engine's Powertrain
Control Module (PCM) determines when to activate the
SKIP SHIFT upshift system. The SKIP SHIFT upshift
system is bypassed when you accelerate very quickly
from a stop.
*30 mph (48 km/h) when accelerating to highway speeds.
**45 mph (72 km/h) when accelerating to highway speeds.
