When the Hybrid Vehicle Shuts
Off
When the high voltage battery is dis-
charged, when the 12-volt battery is
discharged, or when the fuel tank is
empty, the hybrid system may not
operate while driving. When the
Hybrid system does not operate, do
the followings:
1. Gradually reduce the vehiclespeed. Pull over your vehicle off
the road in a safe area.
2. Locate the shift lever in P (Park).
3. Turn ON the hazard warning flash- ers.
4. Turn OFF the vehicle, and try to start the hybrid system again,
while depressing the brake pedal
and turning on the Engine
Start/Stop button. 5. When the hybrid system still does
not operate, refer to ''If the 12 Volt
Battery Is Discharged'' in chapter 6.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For fur-
ther details, refer to ''If the 12 Volt
Battery Is Discharged'' in the
chapter 6. When the fuel level is
low, do not attempt to drive the
vehicle only with the battery
power. The high voltage battery
may be discharged, and the hybrid
system will turn OFF.
