Auto power off function
If the vehicle is left in ACCESSORY mode
for more than 20 minutes or ON mode
(with hybrid system not operating) for more
than an hour with the shift position in P, the
power switch will automatically turn off.
However, this function cannot entirely pre-
vent the 12-volt battery discharge. Do not
leave the vehicle with the power switch in
ACCESSORY or ON mode for long peri-
ods of time when the hybrid system is not
operating.
■ When the shift control system malfunc-
tions
When attempting to turn the power switch
off while there is a malfunction in the shift
control system, the power switch mode may
change to ACCESSORY mode. In this
case, ACCESSORY mode may be turned
off by applying the parking brake and press-
ing the power switch again. If there is a mal-
function in the system, have the vehicle
inspected by your Lexus dealer immedi-
ately.
NOTICE
■ To prevent 12-volt battery discharge
● Do not leave the power switch in
ACCESSORY or ON mode for long
periods of time without the hybrid sys-
tem on.
● If “ACCESSORY” or “IGNITION
ON” is displayed on the meter, the
power switch is not off. Exit the vehicle
after turning the power switch off.
