2004 CHEVROLET EPICA Owners Manual

Ignition Positions
With the key in the
ignition switch, you
can turn the key to
four different positions.
Notice:If your key seems stuck in LOCK and you
can not turn it, be sure you are using the correct
key; if so, is it all the way in? If it is, then turn
the steering wheel left and right while you turn
the key hard. Turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of these works, then
your vehicle needs service.LOCK:This position locks your steering wheel, ignition,
shift lever and transaxle. This is the only position in
which you can insert or remove the key. For easier key
operation when unlocking the steering wheel, move the
steering wheel from right to left and turn the key to ACC.
ACC (ACCESSORY):This position operates some of
your electrical accessories, such as the radio, but
not the ventilation fan.
ON:This is the position to which the switch returns
after you start your engine and release the key.
The switch stays in ON when the engine is running.
But even when the engine is not running, you can use
ON to operate your electrical accessories, and to display
some instrument panel warning lights.
START:This position starts the engine. When the
engine starts, release the key. The switch will return to
ON for normal driving. Do not turn the key to START
if the engine is running.
Even if the engine is not running, ACC and ON allow
you to operate electrical accessories, such as the radio.

Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
1. With your foot off 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 does not start, wait about 15 seconds and try
again to start the engine by turning the ignition key to
START. Wait about 15 seconds between each try.When your engine has run about 10 seconds to
warm up, your vehicle is ready to be driven.
Do not race your engine when it is cold.
If the weather is below freezing (32°F or 0°C),
let the engine run for a few minutes to warm up.
3. If your engine still will not 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,
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 do not, your engine
might not perform properly.
2-20

Engine Coolant Heater
Your vehicle has an engine coolant heater. In very cold
weather 0°F (−18°C) or colder, the engine coolant heater
can help. You will 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.
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 near the battery.
3. Plug the cord 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 re. You could be seriously
injured.Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not 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 do not, 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 will be
parking your vehicle. The dealer can give you the
best advice for that particular area.
2-21

Automatic Transaxle Operation
The automatic transaxle
has a shift lever located
on the console between
the seats.
There are seven different positions for the automatic
transaxle.
The instrument cluster has a shift lever position indicator
that shows which position the shift lever is in. This
indicator is located on the top right side of the instrument
cluster.
Movement between certain positions requires pushing
the shift lever toward the passenger side while shifting.
This prevents you from changing positions unexpectedly
by blocking the straight movement of the shift lever
while the vehicle is moving. It is also necessary to push
down on the shift lever to shift from NEUTRAL (N) to
REVERSE (R).PARK (P):This position locks your front wheels.
It is the best position to use when you start your engine
because your vehicle cannot 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 rmly set. Your vehicle can roll.
Do not 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 will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
SeeShifting Into Park (P) on page 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 apply your regular
brake before you can shift from PARK (P) when the
ignition key is in ON. If you cannot shift out of PARK (P)
while holding the brake pedal down, seeShifting Out
of Park (P) on page 2-28.
2-22

REVERSE (R):Use this gear to back up.
When shifting from NEUTRAL (N) to REVERSE (R), you
must press down on the shift lever and push it toward
the passenger side of the vehicle while shifting.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle. The
repairs would not be covered by your warranty. 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 transaxle, seeIf You
Are Stuck: In Sand, Mud, Ice or Snow on page 4-28.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart while you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine racing may damage the transaxle.
The repairs would not be covered by your warranty.
Be sure the engine is not racing when shifting
your vehicle.
AUTOMATIC OVERDRIVE (D):This position is for
normal driving.
THIRD (3):This position gives you 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 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:Do not drive in SECOND (2) at speeds over
65 mph (105 km/h), or you can damage the transaxle.
Use THIRD (3) or AUTOMATIC OVERDRIVE (D) as
much as possible. Do not shift into SECOND (2)
unless you are going slower than 65 mph (105 km/h)
or you can damage your engine.
2-23

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
shift lever is put in FIRST (1), the transaxle will not shift
into first gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Adaptive Shift Logic
Your automatic transaxle will automatically select from
three adaptive shift patterns based upon driver behavior:
•Economy mode provides a softer shift feel and
optimizes fuel economy.
•Normal mode provides a solid shift feel and is used
for normal driving conditions.
•Sport mode provides a firm shift feel and optimizes
performance.The driver cannot manually select the shift pattern. The
adaptive shift logic tries to operate in economy mode
as much as possible. Normal and sport modes are used
as little as possible in order to maximize fuel economy.
The first few shifts of every drive cycle may be
somewhat rough until the adaptive shift logic has
learned the driver’s behavior. This is normal.
The transaxle also has the ability to adapt to changing
road grade conditions. It will shift between three
different load settings:
•Load 1 is designed for driving on moderate road
grades.
•Load 2 is designed for driving on steep road
grades.
•Load 3 is designed for driving downhill and allows
for better engine braking.
If there is a malfunction with the automatic transaxle, the
malfunction indicator lamp (MIL) or the HOLD indicator
light will turn on or flash. SeeMalfunction Indicator Lamp
on page 3-39orHold Mode Light on page 3-38.
Have your vehicle fixed as soon as possible.
2-24

Hold Mode
Your vehicle’s transaxle has a hold mode.
Press the HOLD button
on the console below
the shift lever to turn
on hold mode.
Press the button again to turn off hold mode, and return
to normal automatic transaxle operation.
While on, the HOLD indicator light on the instrument
panel will light up. SeeHold Mode Light on page 3-38.
When hold mode is activated, the transaxle operates
in the following ways:
•When the transaxle is in AUTOMATIC
OVERDRIVE (D), the transaxle operates in a gear
range of SECOND (2) to THIRD (3) to AUTOMATIC
OVERDRIVE (D) and tries to maintain AUTOMATIC
OVERDRIVE (D) for as long as possible.
•When the transaxle is in THIRD (3), the transaxle
operates in a gear range of SECOND (2) to
THIRD (3) and tries to maintain THIRD (3) for as
long as possible.
•When the transaxle is in SECOND (2), the transaxle
is fixed in that gear.
•When the transaxle is in FIRST (1), the transaxle is
fixed in that gear.
Hold Mode Functions
Winter Function
Select hold mode while in AUTOMATIC OVERDRIVE (D),
THIRD (3) or SECOND (2) to help the vehicle maintain
traction on slippery road surfaces, such as snow, mud,
or ice.
Avoid Excessive Shifting
Select hold mode while in THIRD (3) to avoid excessive
shifting when the adaptive shift logic is not enough to
prevent excessive shifting when driving in hilly areas.
Manually Controlling Shift
Select hold mode to use your automatic transaxle like
a four-speed manual transaxle.
2-25

Parking Brake
The parking brake lever is located between the bucket
seats.To set the parking brake, hold the brake pedal down
and pull up on the parking brake lever. If the ignition is
on, the brake system warning light will come on.
SeeBrake System Warning Light on page 3-35.
To release the parking brake, hold the brake pedal
down. Pull the parking brake lever up until you can press
the release button. Hold the release button in as you
move the brake lever all the way down.
If you forget to release the parking brake prior to driving
away, a chime will sound to remind you to release
the parking brake.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
