5-2. Steps to take in an emergency
RX350/270_EE
Emergency start function
When the engine does not start, the following steps can be used as an
interim measure to start the engine if the “ENGINE START STOP” switch
is functioning normally:
Set the parking brake.
Shift the shift lever to P.
Turn the “ENGINE START STOP” switch to ACCESSORY
mode.
Press and hold the “ENGINE START STOP” switch for about 15
seconds while depressing the brake pedal firmly.
Even if the engine can be started using the above steps, the system may
be malfunctioning. Have the vehicle checked by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
■The starter motor does not turn over, the interior lights and head-
lights 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 battery terminals may be disconnected.
●The battery may be discharged. (→P. 5 9 4 )
●There may be a malfunction in the steering lock system.
Contact any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional if the problem cannot be repaired, or if
repair procedures are unknown.
