Roadside Emergencies
If the engine still does not start after the first complete high voltage
jump start, a second jump start procedure can be attempted after a
two-minute period (indicated by the button light changing from a rapid
flash to no illumination). This jump start procedure can only be done
twice before the low voltage (underhood) battery becomes discharged
and must also be jump started.
If the jump start button is pressed, but the indicator on the button
flashes slowly, the low voltage (underhood) battery may not have enough
energy to charge the high voltage battery. If this occurs, refer to the
Jump starting your vehicle (Low voltage [underhood] battery only)
section in this chapter for information on jump starting the low voltage
(underhood) battery. You may perform another high voltage battery jump
start by pressing the jump start button after having connected the
jumper cables and starting the booster vehicle.
Once the engine is started, the jumper cables should be removed as
described in the Jump starting your vehicle (Low voltage
[underhood] battery only) section.
