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.
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 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.
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.
Starter Interlock Feature
For your convenience and to avoid damage to your
starter, your vehicle is equipped with a starter interlock
feature. This feature will not allow you to crank the
engine when the vehicle is already running.

2-26
Racing or Other Competitive Driving
See your Warranty Book before using your vehicle for
racing or other competitive driving.
NOTICE:
If you use your vehicle for racing or other
competitive driving, your engine may use more
oil than it would with normal use. Low oil levels
can damage the engine. Be sure to check the oil
level often during racing or other competitive
driving and keep the level at or near 1 quart (1 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
For information on how to add oil, see ªAdding
Oilº under ªEngineº in the Index. After the
competitive driving, remove excess oil so that the
level on the dipstick is not above the upper mark
that shows the proper operating range.
Engine Coolant Heater (Canada Only)
The engine coolant heater is located on the driver's side
of the engine under the manifold.
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. At temperatures above 32
F (0
C),
use of the coolant heater is not required.

2-27 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is attached to the generator
bracket assembly, between the generator and the
windshield washer fluid tank.With the headlamps
closed, route the cord in the opening between the
headlamp door and the fender panel on the driver's
side of the vehicle. Do not pinch the cord when
closing the hood.
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 position 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.
Be sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system.

2-29
You have to fully apply your regular brakes before you
can shift from PARK (P) when the ignition key is in ON.
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 release the shift lever button as you
maintain brake application. Then press the shift lever
button and move the shift lever into the gear you wish.
If you do not apply the brake after 15 seconds once the
ignition is turned on, you will receive a PRESS BRAKE
BEFORE SHIFT message in the Driver Information
Center (DIC). 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.
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.

2-30
AUTOMATIC OVERDRIVE (
): This position is
for normal driving.
THIRD (3): 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 THIRD (3)
instead of AUTOMATIC OVERDRIVE (
):

When driving on hilly, winding roads.

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 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.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), the transmission
won't shift into first gear 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.

2-31
Manual Transmission Operation
This is the shift pattern
for the 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 40 mph (64 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).
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.THIRD (3), FOURTH (4), FIFTH (5) and
SIXTH (6): Shift into THIRD (3), FOURTH (4),
FIFTH (5) and SIXTH (6) 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 the brake pedal, and shift to NEUTRAL.
NEUTRAL: Use this position when you start or idle
your engine. Your shift lever is in NEUTRAL when it is
centered in the shift pattern, not in any gear.
REVERSE (R): To back up, press down the clutch
pedal and shift into REVERSE (R). Just apply pressure
to get the lever past FIFTH (5) and SIXTH (6) into
REVERSE (R). Let up on the clutch pedal slowly while
pressing the accelerator pedal.
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 3 mph (5 km/h)).
You will be locked out if you try to shift into
REVERSE (R) while your vehicle is moving faster
than 3 mph (5 km/h). If you have turned your ignition
off and wish to park your vehicle in REVERSE (R),
you will have to move the shift lever quickly to the
right, and immediately forward into gear.

2-32
Shift Speeds (Manual Transmission)
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 the best fuel economy.
If your engine speed drops below 900 rpm, 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 engine performance.
NOTICE:
When you are shifting gears, don't move the
gearshift lever around needlessly. This can
damage parts of the transmission and may
require costly repair. Shift directly into the
next appropriate gear.

2-33 One to Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1)
to SECOND (2).
You must complete the shift into FOURTH (4) to turn
off this feature. This helps you get the best possible
fuel economy.
After shifting to FOURTH (4), you may downshift
to a lower gear if you prefer.
NOTICE:
Do not try to force the shift lever into SECOND (2)
or THIRD (3) when the 1 TO 4 SHIFT light
comes on. Do not try to re
-engage FIRST (1)
after starting to shift into FOURTH (4). You will
damage your transmission. Shift only from
FIRST (1) to FOURTH (4) when the light
comes on.
This light will come on when:

The engine coolant temperature is higher than
169F (76C),

you are going 15 to 19 mph (24 to 31 km/h) and

you are at 21 percent throttle or less.

2-34
Downshifting (Manual Transmission)
Do not downshift into the gear shown below at a speed
greater than shown in the table:
FIRST (1) 50 mph (80 km/h). . . . . . . . . . . . . . . . . . . .
SECOND (2) 74 mph (119 km/h). . . . . . . . . . . . . . . .
THIRD (3) 101 mph (163 km/h). . . . . . . . . . . . . . . . .
FOURTH (4) 130 mph (209 km/h). . . . . . . . . . . . . . .
NOTICE:
If you skip more than one gear when you
downshift, or if you race the engine when you
downshift, you can damage the engine, clutch,
driveshaft or transmission.
The six-speed transmission has a spring that centers
the gearshift lever near THIRD (3) and FOURTH (4).
This spring helps you know which gear you are in
when you are shifting. Be careful when shifting from
FIRST (1) to SECOND (2) or downshifting from
SIXTH (6) to FIFTH (5). The spring will try to pull
the gearshift lever toward FOURTH (4) and THIRD (3).
Make sure you move the lever into SECOND (2) or
FIFTH (5). If you let the gearshift lever move in the
direction of the pulling, you may end up shifting
from FIRST (1) to FOURTH (4) or from SIXTH (6)
to THIRD (3).
