Starting Your Northstar V8 Engine
1. Without pushing the accelerator pedal, turn your
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 right away, hold your key in
START for about three seconds at a time until your
engine starts. Wait about 15 seconds between each
try to help avoid draining your battery or damaging
your starter.3. 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. If the vehicle starts
briefly but then stops again, do the same thing.
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 (If Equipped)
A. Engine Oil Dipstick Location
B. Engine Coolant Heater Cord
C. Transaxle Dipstick/Fluid Fill LocationIn 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver's side of
the engine, behind the transaxle dipstick/fluid fill
location (C) and next to the engine.
3. Plug it into a normal, grounded 110
-volt AC outlet.

2-25
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 Transaxle Operation
The automatic transaxle may have either a shift lever
located on the steering column or on the console
between the seats.
There are several different positions for the shift lever.
Console Shifter

2-26
Column Shifter (Digital and Analog Cluster similar)
PARK (P): This position locks the front wheels. It's the
best position to use when you start the 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.

2-27
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transaxle 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 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) as
you maintain brake application. Then move the shift
lever into the gear you wish. 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 transaxle.
Shift to REVERSE (R) only after your vehicle
has stopped.
Also use this gear to rock your vehicle back and forth to
get out of snow, ice or sand without damaging your
transaxle. See ªStuck in Sand, Mud, Ice or Snowº in
the Index for additional information.
NEUTRAL (N): In this position, the 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.

2-28
NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn't covered by your warranty.
DRIVE (D): This position is for normal driving. If you
need more power for passing, and you're:

Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it doesn't seem to shift gears as you accelerate,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and DRIVE (D) for
higher speeds.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than DRIVE (D).
Here are examples for using THIRD (3) instead of
DRIVE (D).

When driving on hilly, winding roads.

When towing a trailer, so there is less shifting
between gears.

When going down a steep hill.

2-29
SECOND (2): This position gives you more power. 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 shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine.
FIRST (1): This position gives you even more power
than SECOND (2). You can use it on very steep hills,
or in deep snow or mud. (If the shift lever is put in
FIRST (1), the transaxle won't shift into gear until the
vehicle is going slowly enough.)
NOTICE:
If your front 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 transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could cause overheating and damage
the transaxle. Use your brakes to hold your
vehicle in position on a hill.
Performance Shifting (DTS Only)
When your vehicle detects a change in driving
conditions, it will automatically initiate the appropriate
performance shift mode. When this occurs the gear
display on the instrument panel cluster will change to
indicate that the transmission has shifted to a different
gear. For example, the gear display on the cluster may
indicate D, 3, 2, or 1 even though the gearshift is still in
DRIVE (D). Once the performance shift mode ends, the
gear display on the cluster will return to normal.

2-30
Parking Brake
Hold the regular brake
pedal down with your right
foot and push the parking
brake pedal down with
your left foot to set the
parking brake.
If the ignition is on, the BRAKE indicator light
should come on. If it doesn't, you need to have your
vehicle serviced.
When you move out of PARK (P) or NEUTRAL (N)
and the engine is running, the parking brake should
release. If the parking brake has not been fully released
and you try to drive off with the parking brake on, the
BRAKE indicator light will come on and stay on.If the brake doesn't fully release, you can manually
release the lever. Before attempting to release the
lever however, be sure to carefully read the
following paragraphs.
CAUTION:
Always shift to PARK (P) before pulling the
manual release lever. If your hand or arm is in
the way of the pedal you could be hurt. The pedal
springs back quickly. Keep your hand and arm
away when you use the manual release lever.
Before releasing the manual parking brake, be sure to
put the vehicle in PARK (P) and turn the ignition
to OFF.

2-32
Shifting Into PARK (P)
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.
Steering Column Shift Lever (If Equipped)
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) like this:

Pull the lever toward you.

2-34
Leaving Your Vehicle With the
Engine Running
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.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move the
shift lever away from PARK (P) without first pulling it
toward you. If you can, it means that the shift lever
wasn't fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. 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.
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 transaxle, so you
can pull the shift lever out of PARK (P).
