{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.

For example, if someone puts in brake linings that are
wrong for your vehicle, the balance between your
front and rear brakes can change — for the worse.
The braking performance you have come to expect can
change in many other ways if someone puts in the
wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has the
replacement number shown on the original battery’s
label. We recommend an ACDelco
®replacement
battery. SeeEngine Compartment Overview on
page 5-12for battery location.
Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm. Wash hands
after handling.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. SeeJump Starting on page 5-46
for tips on working around a battery without
getting hurt.
After a power loss, such as disconnecting the battery or
removing the maxi fuses in the power distribution
fuse block, the following steps must be performed to
calibrate the electronic throttle control. If this is not done,
the engine will not run properly.
1. Turn the ignition key to ON. Do not start the engine.
2. Leave the ignition in ON for at least three minutes
so that the electronic throttle control will cycle and
re-learn its home position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least 30 seconds.
Also, for your audio system, seeTheft-Deterrent Feature
on page 3-124.

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to follow the steps below to do it safely.
{CAUTION:
Batteries can hurt you. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlets. Turn off
the radio and all lamps that aren’t needed. This will
avoid sparks and help save both batteries. And it
could save your radio!

4. Open the hoods and locate the batteries. Find the
positive (+) and negative (−) terminal locations on
each vehicle. SeeEngine Compartment Overview
on page 5-12for more information on location of
the battery.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from any
underhood electric fan.
{CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the ACDelco
®battery
installed in your new vehicle. But if a battery
has ller caps, be sure the right amount of
uid is there. If it is low, add water to take care
of that rst. If you do not, explosive gas could
be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place
with water and get medical help immediately.
5-47

{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.
5. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a
shock. The vehicles could also be damaged, too.
Before you connect the cables, here are some basic
things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if the
vehicle has one. Negative (−) will go to a heavy,
unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Notice:If you connect a negative cable to the ECM,
ECM mounting bracket or any cables that attach
to the ECM bracket, you may damage the ECM.
Attach the negative cable to a heavy, unpainted
metal engine part, other than the ECM, ECM bracket
or cables attached to the ECM bracket.Don’t connect positive (+) to the negative (−)oryou
will get a short that would damage the battery
and maybe other parts, too. And don’t connect the
negative (−) cable to negative (−) terminal on
the dead battery because this can cause sparks.
6. Connect the red positive (+) cable to the positive (+)
terminal of the dead battery. Use a remote
positive (+) terminal if the vehicle has one.
5-48

7. Don’t let the other end
touch metal. Connect it
to the positive (+)
terminal of the good
battery. Use a remote
positive (+) terminal
if the vehicle has one.
8. Now connect the black
negative (−) cable to
the negative terminal of
the good battery.
Use a remote
negative (−) terminal if
the vehicle has one.Don’t let the other end touch anything until the next
step. The other end of the negative (−) cable doesn’t
go to the dead battery. It goes to a heavy, unpainted
metal engine part or to a remote negative (−)
terminal on the vehicle with the dead battery.
9. Connect the other end
of the negative (−)
cable at least 18 inches
(45 cm) away from
the dead battery, but
not near engine
parts that move.
The electrical connection is just as good there, and
the chance of sparks getting back to the battery
is much less.
10. Now start the vehicle with the good battery and
run the engine for a while.
11. Try to start the vehicle that has the dead battery.
If it won’t start after a few tries, it probably
needs service.
