Jump Starting Procedure - RAM Commercial CHASSIS CAB 3500 2021 Owner's Manual

3. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cables reach, apply the parking brake, and
make sure the ignition is OFF.
WARNING!
Take care to avoid the radiator cooling fan

whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
Remove any metal jewelry such as rings,

watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
Batteries contain sulfuric acid that can

burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.

WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged vehicle.
NOTE:
Make sure at all times that unused ends of
jumper cables are not contacting each other or
either vehicle while making connections.
Connecting The Jumper Cables
1. Connect the positive (+) end of the jumper
cable to the positive (+) post of the
discharged vehicle.
NOTE:
Do not jump off fuses. Only jump directly off
positive post.
IN CASE OF EMERGENCY
2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.
3. Connect the negative (-) end of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to a good engine ground.
A "ground" is an exposed metallic/
unpainted part of the engine, frame or
chassis, such as an accessory bracket or
large bolt. The ground must be away from
the battery and fuel injection system.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause the
battery to explode and could result in
personal injury.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
