Jump Starting
If the vehicle is a hybrid, see
the hybrid supplement for more
information.
If the vehicle's battery (or batteries)
has run down, you may want to use
another vehicle and some jumper
cables to start your vehicle. Be sure
to use the following steps to do it
safely.
{WARNING
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
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the
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. If you have a vehicle with a
diesel engine with two batteries,
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, using the battery
that is closer to the starter will
reduce electrical resistance.
This is located on the passenger
side, in the rear of the engine
compartment.

3. Get the vehicles close enoughso the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they are,
it could cause an unwanted
ground connection. You would
not 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 the automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If you have a four-wheel-drive
vehicle, be sure the transfer
case is in a drive gear, not in
Neutral. Notice:
If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories
when jump starting the vehicle.
4. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all the lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio! 5. Open the hood on the
other vehicle and locate the
positive (+) and negative (−)
terminal locations on that
vehicle.
The positive (+) terminal, is
located under a red plastic
cover at the positive battery
post. To uncover the positive (+)
terminal, open the red plastic
cover.
If your vehicle has a gasoline
engine, the remote negative (−)
terminal is a stud located on the

Black plate (98,1)Chevrolet Silverado Owner Manual - 2011
10-98 Vehicle Care
right front of the engine, where
the negative battery cable
attaches.
If your vehicle has a diesel
engine, the remote negative (−)
terminal is the negative (−) post
on the auxiliary battery on
the driver side of the engine
compartment.
For more information on
the location of the remote
positive (+) and remote
negative (−) terminals, see
Engine Compartment Overview
on page 10‑6
{WARNING
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.
{WARNING
Using an open flame 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 do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right(Continued)
WARNING (Continued)
amount of fluid is there. If it is low,
add water to take care of that
first. If you do not, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not 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.
{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.

6. Check that the jumper cablesdo not 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.
Do not connect positive (+) to
negative (−) or you will get a
short that would damage the
battery and maybe other parts
too. And do not connect the
negative (−) cable to the
negative (−) terminal on the
dead battery because this
can cause sparks.

and 6.2L similar)
7. Connect the red positive (+) cable to the positive (+) terminal
of the vehicle with the dead
battery.
8. Do not 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. 9. Now connect the black
negative (−) cable to the
negative (−) terminal of the
good battery. Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step.
10. Connect the other end of the negative (−) cable to a heavy,
unpainted metal engine part
or to the remote negative (−)
terminal, on the vehicle with
the dead battery.
11. 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 will
not start after a few tries, it
probably needs service.

connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the
cables do not touch each other
or other metal.
