Warning
For safety and the protection of the
vehicle, do not push-start the vehicle.
Never tow the vehicle to start because a
surge forward when the engine starts
could cause a collision with the tow
vehicle.
Also, this vehicle has a 12-volt battery,
12-volt starting system and a negative
ground electrical system; be sure the
vehicle or equipment used to jump start
your engine is also 12-volt. Use of any
other system may damage the vehicle's
electrical components.
Under no circumstances should the
battery's positive and negative terminals
be put in contact with one another.
When connecting the cables, under no
circumstances should the clips be allowed
to touch each other.
Do not disconnect a battery terminal
with the engine running. It could cause a
breakdown in the electrical system.
You and others could be seriously injured.
Warning
WARNING: Battery posts, terminals and
related accessories can expose you to
chemicals including lead and lead
compounds, which are known to the
State of California to cause cancer and
birth defects or other reproductive harm.
Wash hands after handling. For more

See the warning on the back cover.
If you notice battery fluid leaking, have an

Diesel engine vehicles have more than one
battery because of the higher torque
required to start a diesel engine. This
procedure can be used to start a
single-battery vehicle from any of the diesel
vehicle's batteries. However, at low
temperatures, it may not be possible to
start a diesel engine from a single battery
from another vehicle.
1. Use a vehicle that has a charged battery
with the same voltage. Make sure that
the other vehicle also has a 12-volt
starting system, and that it is the

(attached to the engine block,
or frame rail).

the vehicles touch. Also, be sure the
booster cables to be used do not have
loose or missing insulation.

(engine control) switch and all lights and
accessories except the hazard flasher or
any lights needed for the work area. In
both vehicles, apply the parking brake
firmly and move the selector lever to the
