CAUTION
■P position switch
Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at extremely low speeds (for exam-
ple, directly before stopping the vehicle), the vehicle may stop suddenly when the
shift position switches to P, which could lead to an accident.
NOTICE
■Situations where P position control system malfunctions are possible
If any of the following situations occurs, P position control system malfunctions are
possible.
Immediately stop the vehicle in a safe place on level ground, apply the parking
brake, and then contact your Lexus dealer.
●When the “P Lock Malfunction” warning message appears on the multi-informa-
tion display. (→P. 5 1 3 )
●When the P position switch indicator flashes.
●When the shift position symbols (such as P and R) are flashing on the shift posi-
tion indicator.
●When the shift position indicator remains off.
■When in heavy traffic
If shift position N is selected, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N position
selected for an extended period of time.
■If the vehicle will not shift out of the P position
There is a possibility that the 12-volt battery is discharged. Check the 12-volt battery
in this situation.
■Notes regarding shift lever and P position switch operation

HS250h_U_75050UPress the “ENTER” switch to
change to OFF.
The “AFS OFF” indicator will come
on.
Each pressing of the switch turns
AFS on and off.
Press the menu switch to change to
the normal display.
■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (at a reduced intensity) whenever the hybrid system is started and the
parking brake is released. Daytime running lights are not designed for use at
night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
■Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
