5-2. Steps to take in an emergency
HS250h_U_75033U(Canada)
Emergency start functionWhen the hybrid system does not start, the following steps can be used as
an interim measure to start the hybrid system if the “POWER” switch is
functioning normally: Set the parking brake.
Turn the “POWER” switch to ACCESSORY mode.
Press and hold the “POWER” switch for about 15 seconds while
depressing the brake pedal firmly.
Even if the hybrid system can be star ted using the above steps, the system
may be malfunctioning. Have the vehicle inspected by your Lexus dealer.
■ The interior lights and headlights do not turn on, or the horn does
not sound.
One of the following may be the cause of the problem:
● One or both of the 12-volt battery terminals may be discon-
nected.
● The 12-volt battery may be discharged. ( →P. 5 3 6 )
Contact your Lexus dealer if the problem cannot be repaired, or if
repair procedures are unknown.

5-2. Steps to take in an emergency
HS250h_U_75033U(Canada)
■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is off.
●Turn off any unnecessary electrical components when the vehicle is running at a
low speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is discharged
●The hybrid system may not start. (→P. 434)
●If the 12-volt battery is depleted with the shift position in P, it will not be possible
to shift out of P. In this case, the vehicle cannot be towed without lifting both
front wheels because the front wheels are locked by the parking lock.
(→ P. 4 8 3 )
●When the 12-volt battery is reconnected, start the hybrid system, depress the
brake pedal, and confirm that it is possible to shift into each shift position.
Close the exclusive jump starting terminal cover and reinstall
the fuse box cover.
Once the hybrid system starts, ha ve the vehicle inspected at your
Lexus dealer as soon as possible.
