JUMP-STARTING
If the vehicle has a discharged battery, booster cables may
be used to obtain a start from a booster battery or the
battery in another vehicle. This type of start can be
dangerous if done improperly, so follow this procedure
carefully.
WARNING!
• Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Do not lean over a battery when attaching
clamps or allow the clamps to touch each other. If
acid splashes in your eyes or on skin, flush the
contaminated area immediately with large quanti-
ties of water.
• A battery generates hydrogen gas which is flam-
mable and explosive. Keep flames or sparks away
from the vent holes.
• Do not use a booster battery or any other booster
source that has a greater than 12-Volt system (i.e.,
do not use a 24-Volt power source).
