2005 CHEVROLET EPICA fuel pump

Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The immobilizer system prevents your vehicle from
being started by unauthorized persons.
If your vehicle has an immobilizer system, your vehicle
has a special key that works with the theft-deterrent
system. There is a transponder in the key head that is
electronically coded. The correct key will start the
vehicle. An invalid key immobilizes the engine. The
immobilizer system isolates the power supply to
the ignition system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the ignition
is turned to LOCK and the key is removed from
the ignition. The security light located on the top center
of the instrument panel, near the windshield, will
flash when the immobilizer is active. If the light does not
flash after removing the key, have the system checked
by your dealer.
The immobilizer system works when you turn the key to
START. If the immobilizer system does not recognize the
electronic code, the engine will not start and the security
indicator will continue blinking. If your key is ever
damaged, you may not be able to start your vehicle.When trying to start the vehicle, if the engine does not
start and the security light continues flashing, the
key may have a damaged transponder. Turn the ignition
off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another key. At this time, you
may also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-77. If the engine still does not
start with the other key, your vehicle needs service. If
your vehicle does start, the first key may be faulty. See
your dealer who can service the theft-deterrent
system to have a new key made.
Up to four keys may be programmed for the vehicle.
If you lose or damage your keys, only a GM dealer can
service the theft-deterrent system to have new
keys made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program
on page 7-5.

Trunk Ajar Light (Sedan)
This light will come on
when the trunk is not
completely closed.
Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
ignition is on.When the tank nears empty, the low fuel warning light
will come on. You still have a little fuel left, but you
should get more soon. SeeLow Fuel Warning Light on
page 3-47for more information.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage:
•At the service station, the gas pump shuts off
before the gage reads full.
•It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
fill the tank.
•The indicator moves a little when you turn a corner
or speed up.
For your fuel tank’s capacity, seeCapacities and
Specifications on page 5-83.

Filling Your Tank
{CAUTION:
Fuel vapor burns violently and a fuel re can
cause bad injuries. To help avoid injuries to
you and others, read and follow all the
instructions on the pump island. Turn off your
engine when you are refueling. Do not smoke
if you are near fuel or refueling your vehicle.
Keep sparks, ames and smoking materials
away from fuel. Do not leave the fuel pump
unattended when refueling your vehicle — this
is against the law in some places. Keep
children away from the fuel pump; never let
children pump fuel.To open the fuel filler door,
pull up on the release
lever located on the floor
on the outboard side of the
driver’s seat.

The tethered fuel cap is located behind a hinged fuel
door on the passenger’s side of the vehicle. To remove
the fuel cap, turn it slowly to the left (counterclockwise).
While refueling, hang the tethered cap inside the
fuel door.
{CAUTION:
If you spill fuel and then something ignites it,
you could be badly burned. Fuel can spray out
on you if you open the fuel cap too quickly.
This spray can happen if your tank is nearly
full, and is more likely in hot weather. Open
the fuel cap slowly and wait for any hiss noise
to stop. Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overfill the
tank, and wait a few seconds after you have finished
pumping before removing the nozzle. Clean fuel
from painted surfaces as soon as possible. See
Washing Your Vehicle on page 5-71.
5-9

When replacing the fuel cap, turn it to the right
(clockwise) until it clicks. Make sure the cap is fully
installed. The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This
would allow fuel to evaporate into the atmosphere. See
Malfunction Indicator Lamp on page 3-41.
{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not t properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp on
page 3-41.
Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if this occurs. To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
Bring the ll nozzle in contact with the
inside of the ll opening before operating
the nozzle. Contact should be maintained
until the lling is complete.
Do not smoke while pumping gasoline.
