If you put things inside your vehicle -- like suitcases,
tools, packages or anything else
-- they will go as fast as
the vehicle goes. If you have to stop or turn quickly, or
if there is a crash, they'll keep going.
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 cargo area of your vehicle.
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.

Don't leave an unsecured child restraint in
your vehicle.

When you carry something inside the
vehicle, secure it whenever you can.

Don't leave a seat folded down unless you
need to.
Power Take-Off (PTO) Switch
(If Equipped)
If your vehicle is equipped
for the addition of a PTO,
this factory installed switch
will be located in the
instrument panel
switchbank.
Before using a PTO, refer to the manufacturer's or
installer's instructions.

Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know you have a problem. Your front and
rear turn signal lamps will flash on and off.
Your hazard warning
flashers button is located on
top of the steering column.
Your hazard warning flashers work no matter what
position your key is in, and even if the key isn't in.
Press the button to make the front and rear turn signal
lamps flash on and off. Press the button again to turn the
flashers off.
When the hazard warning flashers are on, your turn
signals won't work. The hazard warning flashers will
not flash if the brakes are applied.

Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road behind your vehicle in the
recommended manner per Federal Motor Carrier Safety
Regulation (FMCSR) Section 392.22, to warn others.
Jump Starting
If your battery (or batteries) 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 don't 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 wouldn't be covered by your
warranty.
The ACDelco battery in your vehicle has a
built
-in hydrometer. Do not charge, test or jump
start the battery if the hydrometer looks clear or
light yellow. Replace the battery when there is a
clear or light yellow hydrometer and a cranking
complaint.
Trying to start your vehicle by pushing or pulling
it won't work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery (or batteries) with a negative ground system.
NOTICE:
If the other system isn't a 12-volt system with a
negative ground, both vehicles can be damaged.

5-4
If you have a diesel engine vehicle with two batteries
(or more), you should know before you begin that,
especially in cold weather, you may not be able to
get enough power from a single battery in another
vehicle to start your diesel engine.
If your vehicle has more than one battery, use the
one closest to the starter
-- this will reduce electrical
resistance.
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 firmly 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 on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or 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!

5-5
4. Open the hood of the other vehicle and locate the
battery. Find the positive (+) and negative (
-)
terminals on that battery.
Open the hood of your
vehicle and find the
remote positive (+)
terminal, located under
a red plastic cover on
the passenger's side of
the vehicle.
Squeeze the tab and open the case to access the
remote positive (+) terminal.
You will not see the battery (or batteries) of your
vehicle under the hood. They are located in the
battery box on the passenger's side of the vehicle.You will not need to access your battery
(or batteries) for jump starting. The remote
positive (+) terminal is for that purpose.
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 flashlight if
you need more light.
Be sure the batteries have enough water. You
don't need to add water to the ACDelco
battery
(or batteries) 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.

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 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.
Don't connect the 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.
6. Connect the red
positive (+) cable
to the positive (+)
terminal of the
dead battery. Use a
remote positive (+)
terminal if the
vehicle has one.

5-7
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 the remote negative (
-)
terminal on the vehicle with the dead battery.
