ECU CHEVROLET CLASSIC 2004 Owner's Manual

Rear Door Security Locks
Your vehicle has rear door security locks that help
prevent passengers from opening the rear doors of your
vehicle from the inside.
The lever for this feature is
located on the inside of
the rear door.
To use the security locks, do the following:
1. Slide the lever up.
2. Close the door.
3. Do the same thing to the other rear door.The rear doors on your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open a rear door while the security lock is on, do
the following:
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you do not cancel the security lock feature, adults or
older children who ride in the rear won’t be able to
open the rear door from the inside. You should let adults
and older children know how these security locks
work, and how to cancel the locks.
To cancel a rear door lock, do the following:
1. Unlock the door from the inside and open it from
the outside.
2. Slide the lever down.
3. Do the same to the other rear door.
The rear doors will now work normally.

Lockout Protection
Lockout protection is intended to provide additional
security and convenience. While any door is open and
the key is in the ignition, the doors cannot be locked
by using the power door locks.
To override this feature, while the key is in the ignition
and any door is open, press and hold down the
power door lock switch for three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle. If the key is not in the ignition,
or if you use the manual door lock or the remote
keyless entry transmitter, you could still lock your key
inside your vehicle. Always remember to take your
key with you.
Leaving Your Vehicle
If you are leaving your vehicle, open your door and set
the locks from the inside, then get out and close the door.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder. When closing the trunk
lid, push the truck lid in the center to ensure that the lock
fully latches.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can’t see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the trunk lid open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See “Climate Control
System” in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
See “Engine Exhaust” in the Index.

Notice:Using the emergency trunk release handle
as a tie-down or anchor point when securing
items in the trunk may damage it. Use the
emergency trunk release handle only to help you
open the trunk lid.
There is a glow-in-the-dark emergency trunk release
handle located inside the trunk on the trunk latch. This
handle will glow following exposure to light. Pull the
release handle up to open the trunk from the inside.Trap-Resistant Trunk Kit
To help prevent a child from becoming trapped in your
trunk, you can order a trap-resistant trunk kit from
your dealer. This kit includes:
•a modified trunk latch,
•a lighted release handle, and
•seatback tethers (for vehicles with folding rear
seatbacks).
See your dealer for additional information.

Include an ice scraper, a small brush or broom, a
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight, a red
cloth and a couple of reflective warning triangles. And, if
you will be driving under severe conditions, include a
small bag of sand, a piece of old carpet or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet
the road probably have good traction.
However, if there is snow or ice between your tires and
the road, you can have a very slippery situation. You
will have a lot less traction or “grip” and will need to be
very careful.
What is the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on.

Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle — such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your vehicle
with all four wheels on the ground) and “dolly towing”
(towing your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).
With the proper preparation and equipment, many
vehicle can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing”, following.
Here are some important things to consider before you
do recreational vehicle towing:
•What’s the towing capacity of the towing vehicle?
Be sure you read the tow vehicle manufacturer’s
recommendations.
•How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.
•Do you have the proper towing equipment?
See your dealer or trailering professional for
additional advice and equipment recommendations.
•Is your vehicle ready to be towed? Just as you would
prepare your vehicle for a long trip, you’ll want to
make sure your vehicle is prepared to be towed. See
Before Leaving on a Long Trip on page 4-20.
Dinghy Towing
To tow your vehicle with all four wheels on the ground,
follow these steps:
1. Position the vehicle to tow and then secure it.
2. Turn the ignition switch to OFF.
3. Set the parking brake.
4-30

{CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, and it can change the way your vehicle
handles. These could cause you to lose
control and crash. Also, overloading can
shorten the life of your vehicle.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.

Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you will need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you are turning with a trailer, make wider turns than
normal. Do this so your trailer will not strike soft
shoulders, curbs, road signs, trees or other objects. Avoid
jerky or sudden maneuvers. Signal well in advance.

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixtureat the surge tank,but only when the
engine is cool. If the surge tank is empty, a special fill
procedure is necessary. SeeEngine Overheating
on page 5-22andCooling System on page 5-25.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
You will find a coolant temperature gage and a low
coolant level warning light on your vehicle’s instrument
panel. SeeEngine Coolant Temperature Gage on
page 3-29andLow Coolant Warning Light on page 3-29.
