Durango 2WD V8-5.7L Hybrid (2009)
Jump Starting: Service and Repair
JUMP STARTING - HYBRID ELECTRIC VEHICLES (HEV) VEHICLES ONLY
WARNING: On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In
addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High
Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury See: Hybrid Drive
Systems/Battery System, Hybrid Drive/Service Precautions
WARNING: Review all safety precautions and warnings in the battery system section. See: Starting and Charging/Battery/Service and
Repair/Procedures/Battery Charging
-
Do not jump start a frozen battery.
-
Do not jump start a maintenance-free battery (if equipped) when indicator dot is yellow or a bright color.
-
Do not jump start a vehicle when the battery fluid is below the top of lead plates.
-
Do not allow jumper cable clamps to touch each other when connected to a booster source.
-
Do not expose battery to or near open flame.
-
Remove metallic jewelry worn on hands or wrists to avoid injury by accidental arcing of battery current.
-
When using a high-output boosting device, do not allow battery voltage to exceed 16 volts. Refer to instructions provided with
device being used.
Failure to follow these instructions may result in personal injury.
CAUTION: When using another vehicle as a booster, do not allow vehicles to touch. Electrical systems can be damaged on either vehicle.
TO JUMP START A DISABLED VEHICLE:
This Hybrid vehicle is equipped with both a 12 Volt battery and a high voltage battery. Either battery may become discharged and cause a no crank
condition as a result of low voltage.
If the 12 Volt battery state of charge is to low and the engine will not crank, the 12 Volt battery light located in the cluster, may illuminate. If this occurs
refer to "Jump-Starting - 12 Volt Battery".
If the high voltage battery state of charge is too low and the engine will not crank, the navigation radio displays a "Charge Insufficient" message. If this
occurs refer to "Jump Assist Procedure - High Voltage Battery".
Jump Assist Procedure - High Voltage Battery
NOTE: When running the Jump Assist mode with the scan tool, ensure the High Voltage Battery contactors are in the close positions. Using
the scan tool view the High Voltage Battery contactors status in the BPCM. If the High Voltage Battery contactors are opened, the
jump assist will not operate. If this happens, cycle the ignition key from off and on without an attempted crank.
The "Jump Assist" procedure allows you to charge the high voltage battery using the 12 Volt battery system. The navigation radio guides you through the
"Jump Assist" procedure.
This message indicates that the vehicle is in "Jump Assist" mode, and can be charged by following the "Jump Assist" procedure. You have
approximately 15 minutes to connect a 12 Volt battery charger and begin charging the system. If you are unable to connect a 12 Volt battery charger
within 15 minutes, turn the ignition key to the START position to re-initiate "Jump Assist" mode.
