ECU CHEVROLET S10 2004 Owner's Manual

Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should but the
vehicle’s headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace
the fuse, seeFuses and Circuit Breakers on page 5-105.
If the alarm does not sound or the vehicle’s headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
Passlock®
Your vehicle is equipped with the
Passlock®theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will
go off approximately five seconds after the key is turned
to RUN.
If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before
trying to restart the engine. Remember to release the
key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if
you turn the engine off. However, your
Passlock
®system is not working properly and must be
serviced by your dealer. Your vehicle is not protected
by Passlock
®at this time. You may also want to check
the fuse. SeeFuses and Circuit Breakers on
page 5-105. See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.

Front Storage Area
If your vehicle has a console compartment, squeeze the
front lever while lifting the top to open it. You can
store cassettes and compact discs in the slots in front of
the compartment. It is located on the floor in the front
of your vehicle.
Assist Handles
Use the assist handle above each passenger door
when getting out of your vehicle.
Garment Hooks
Your vehicle is equipped with garment hooks. They are
located on the headliner in front of the assist handles.
Luggage Carrier
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier — like paneling, plywood, a mattress
and so forth — the wind can catch it as you
drive along. This can cause you to lose
control. What you are carrying could be
violently torn off, and this could cause you or
other drivers to have a collision, and of course
damage your vehicle. You may be able to carry
something like this inside. But, never carry
something longer or wider than the luggage
carrier on top of your vehicle.
If your vehicle is equipped with a luggage carrier, it may
have side rails and crossrails attached to the roof to
secure cargo. The adjustable tie downs, at both ends of
the crossrails, should be used to secure loads to the
luggage carrier. Use GM accessory racks that are
compatible with your luggage carrier for transporting
sports equipment. These are available through
your dealer.
2-40

You can adjust the crossrails to handle loads of various
sizes. Just loosen the slider knobs at each end of
the crossrail and move them to where you want them.
Make sure both sides of the crossrails are even,
then tighten the slider knobs.
Be sure the cargo is properly loaded. Follow these
guidelines:
•Carrying small, heavy loads on the roof is not
recommended.
•Secure the load using the tie downs at both ends of
the crossrails. When loading cargo directly on the
roof panel, use the crossrails to keep the load from
shifting.
•If you need to carry long items, move the crossrails
as far apart as possible. Tie the load to the tie
downs provided. Also tie the load to the bumpers.
Do not tie the load so tightly that the crossrails
or side rails are damaged.
Notice:Loading cargo on the luggage carrier that
weighs more than 100 lbs. (45 kg) or hangs over the
rear or sides of the vehicle may damage your
vehicle. Load cargo so that it rests on the slats as
far forward as possible and against the side
rails, making sure to fasten it securely.Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading seeLoading Your Vehicle on
page 4-42.
To prevent damage or loss of cargo as you’re driving,
check now and then to make sure the luggage
carrier and cargo are still securely fastened.
Bed Rails
{CAUTION:
If your vehicle has bed rails, they are there for
appearance only. If you try to tie down a load
with them, or to secure things in your truck,
not only can it damage the bed rails, but the
load can loosen. This could cause injury to
you or others. Secure loads by using the cargo
tie-down loops, inside the truck bed area.

Off-Road Driving with Your
Four-Wheel-Drive Vehicle
This off-road guide is for vehicles that have four-wheel
drive.
Also, seeAnti-Lock BrakesunderBraking on page 4-6.
Off-road driving can be great fun. But it does have
some definite hazards. The greatest of these is
the terrain itself.
“Off-roading” means you have left the great North
American road system behind. Traffic lanes are not
marked. Curves are not banked. There are no
road signs. Surfaces can be slippery, rough, uphill or
downhill. In short, you have gone right back to nature.
Off-road driving involves some new skills. And that
is why it is very important that you read this guide. You
will find many driving tips and suggestions. These
will help make your off-road driving safer and more
enjoyable.
Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields (if so equipped) are properly
attached. Be sure you read all the information about
your four-wheel-drive vehicle in this manual. Is
there enough fuel? Is the spare tire fully inflated? Are
the fluid levels up where they should be? What are the
local laws that apply to off-roading where you will be
driving? If you do not know, you should check with law
enforcement people in the area. Will you be on
someone’s private land? If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road
Driving
There are some important things to remember about
how to load your vehicle.
•The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.
•Be sure the load is secured properly, so driving on
the off-road terrain does not toss things around.
4-14

{CAUTION:
Cargo on the load oor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by ying objects. Secure the cargo
properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the
roof. Keep cargo in the cargo area as far
forward and low as possible.
You will find other important information in this manual.
SeeLoading Your Vehicle on page 4-42,Luggage
Carrier on page 2-40andTires on page 5-61.
Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However, it also raises environmental
concerns. GM recognize these concerns and urge every
off-roader to follow these basic rules for protecting
the environment:
•Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving; obey all posted regulations.
•Avoid any driving practice that could damage the
environment — shrubs, flowers, trees, grasses — or
disturb wildlife (this includes wheel-spinning,
breaking down trees or unnecessary driving through
streams or over soft ground).
•Always carry a litter bag — make sure all refuse is
removed from any campsite before leaving.
•Take extreme care with open fires (where permitted),
camp stoves and lanterns.
•Never park your vehicle over dry grass or other
combustible materials that could catch fire from the
heat of the vehicle’s exhaust system.
4-15

Winter DrivingHere are some tips for winter driving:
•Have your vehicle in good shape for winter.
•You may want to put winter emergency supplies in
your vehicle.
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.
