watch bands and bracelets that could make
an inadvertent electrical contact. You could be

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 remote positive (+) post of the
discharged vehicle.
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 the remote negative (-) post
(exposed metallic/unpainted post of the
discharge vehicle) located directly in front of
the underhood fuse box.
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.
IN CASE OF EMERGENCY
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.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle
engine.
6. Once the engine is started, follow the discon-
necting procedure.
NOTE:
Once "READY" has been achieved, the vehicle
should remain in "READY" mode for a few minutes
to charge the depleted battery. On a PHEV, the
engine may not necessarily fire. However, once
"READY" is achieved, the IDCM will support the
12 Volt battery.
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the jumper
cable from the remote negative (-) post of the
discharged vehicle.
2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery.
