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.
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 (N) and let up on the clutch. Press
the clutch pedal back down. Then shift into FIRST (1).
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 (N).
NEUTRAL (N): 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.
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 (N) 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.

2-34
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 (N).
NEUTRAL (N): 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 (N) 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 more than one 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.

2-35
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 this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
This helps you get the best possible fuel economy.The light 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% throttle or less.
When the skip shift light is on, the gearshift lever will
let you shift from FIRST (1) to FOURTH (4) only. Once
you are in FOURTH (4), you can press the clutch again
and shift into another gear.
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.

NOTICE:
Driving with the parking brake on can cause
your parking brakes to overheat. You may have
to replace them, and you could also damage other
parts of your vehicle.
If you are towing a trailer and are parking on any hill,
see ªTowing a Trailerº in the Index. That section shows
what to do first to keep the trailer from moving.
Shifting Into PARK (P)
(Automatic Transmission Only)
CAUTION:
It can be 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.
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, use the steps
that follow. If you're pulling a trailer, see
ªTowing a Trailerº in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake.

2. Move the shift lever into PARK (P) by holding in the
button on the lever and pushing the lever all the way
toward the front of your vehicle.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave the vehicle with the ignition key in your hand,
your vehicle is in PARK (P).
Leaving Your Vehicle With the Engine
Running (Automatic Transmission Only)
CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.

2-39 Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver's seat. To find out how, see ªShifting Into
PARK (P)º in the Index.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
(Automatic Transmission Only)
CAUTION:
Before shifting out of PARK (P) you must fully
apply your regular brakes. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. If you're pulling a trailer, see ªTowing a
Trailerº in the Index.
Your vehicle has a Brake-Transmission Shift Interlock
(BTSI). You have to fully apply your regular brake
before you can shift from PARK (P) when the ignition is
in RUN. See ªAutomatic Transmissionº in the Index.

Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While You're
Parked (Automatic Transmission)
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control system
off could allow dangerous exhaust into your
vehicle (see the earlier Caution under
ªEngine Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
(See ªBlizzardº in the Index.)
