engine GMC SIERRA DENALI 2003 Owners Manual

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
flashlight if you need more light.
Be sure the battery has enough water.
You don’t need to add water to the ACDelco@
battery installed in your new vehicle. But
if
a battery has filler caps, be sure the right
amount of fluid is there. If
it is low, add water
to take care of that first. If you don’t, explosive
gas could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
I
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 be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive
(+) will go to
positive
(+) or a remote positive (+) terminal if the
vehicle has one. Negative
(-) will go to a heavy,
unpainted metal engine part or a remote
negative
(-) terminal if the vehicle has one.
Don’t connect positive
(+) to negative (-) or you’ll
get a short that would damage the battery and
maybe other parts too. And don’t connect the
negative
(-) cable to the negative (-) terminal on
the dead battery because this can cause sparks.

I 10. Connect the other
end of the
negative
(-) cable
to the negative
(-)
terminal of the dead
battery or to a remote
negative
(-) terminal
if the vehicle has one.
11. Now start the vehicle with the good battery and run
the engine for a while.
12. Try to start the vehicle that had the dead battery.
If it won’t start after a few tries, it probably needs
service.
Notice: Damage to your vehicle may result from
electrical shorting if jumper cables are removed
incorrectly.
To prevent electrical shorting, take care
that the cables don’t touch each other or any
other metal. The repairs wouldn’t be covered by
your warranty.

to a stop - well off the road if possible.
If a tire goes flat, the next part shows how
to use your
jacking equipment to change a flat tire safely.
C..-nging a tire can cause
an injury. The
vehicle can slip
off the jack and roll over you
or other people. You and they could be badly
injured. Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
4. Put the wheel blocks at the front and rear
of the tire farthest away from the one
being changed. That
would be the tire on
the other side of the vehicle, at the
opposite end.
