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 Catera 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 Cateraº in the Index.
Engine Coolant Heater (If Equipped)
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.

2-20 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord for the engine coolant heater is in
front of the air cleaner filter and under the headlamp
cover, on the passenger's side of the engine.
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 the shift lever.
PARK (P): This position locks the transmission drive
shaft. 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.
Ensure the shift lever is fully in PARK (P) before starting
the engine.

2-22
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the 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 this section.
REVERSE (R): Use this gear to back up.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging the transmission, see
ªStuck: In Sand, Mud, Ice or Snowº in the Index.
NEUTRAL (N): The engine doesn't connect with
the wheels when driving in NEUTRAL (N). Use
NEUTRAL (N) to restart your vehicle when you're
already moving or 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 the transmission caused by shifting
out of PARK (P) or NEUTRAL (N) with the
engine racing isn't covered by your warranty.

2-23
DRIVE (D): Use this 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 transmission will shift down to the next gear.
THIRD (3): This position is not used for normal
driving. It offers more power and lower fuel economy
than DRIVE (D).
Here are some times you might choose 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.
SECOND (2): Driving in this position gives you more
power than driving in THIRD (3). Use it on hills. It can
help control your speed as you go down steep mountain
roads, but then you would also want to use the brakes
off and on.FIRST (1): This position gives you more power (but
lower fuel economy) than SECOND (2). You can use it
on very steep hills. If the shift lever is put in FIRST (1),
the transmission won't shift into first gear until the
vehicle is going slowly enough.
NOTICE:
If the rear wheels can't rotate, don't try to drive.
This might happen if you were stuck in very
deep sand or mud or you were up against a
solid object. You could damage the 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 the brakes to hold your
vehicle in position on a hill.
When you start your vehicle and the engine temperature
is below 86F (30 C), upshifting of the transmission
will be delayed for about one minute. This is normal.
The engine's catalytic converter is warming up during
this time.

2-24
Upshifting and downshifting of the transmission is
automatically modified to prevent undesired shifting
when your vehicle is towing a trailer or when you
are driving in hilly or mountainous terrain. This is
also normal.
Sport Mode Button
For a firmer shift and
increased performance,
you may choose the sport
mode. This button lets
you change from a normal
driving mode to a sport
driving mode. It is located
on the shift lever handle.
Press the ªSº button once to select the sport feature.
Press it again to return to the normal driving mode.When you start the engine, your vehicle will be in
normal mode. For general driving conditions, use the
normal mode. It will remain in normal unless you select
the sport feature.
This light on the instrument
panel cluster will come
on when the sport mode
is selected.
If this light begins flashing while you are driving, there
may be a fault in the automatic transmission. Have your
vehicle serviced.

2-27
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.
Console Shift Lever
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) like this:

Pull the button on the shift lever handle up
and then push the shift lever all the way toward
the front of your vehicle into PARK (P).
Release the button.

With your right foot still holding the brake pedal
down, set the parking brake.

2-28
3. Turn the ignition key to LOCK.
4. Remove the ignition key and take it with you.
If you can leave your vehicle with the key in your
hand, your vehicle is in PARK (P).
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 the
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 pressing the
button on the shift lever handle. 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
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.
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).
