Jump Starting 

The 12-Volt auxiliary battery may be jump started if the vehicle does not start 
and the instrument cluster gauges are dim or off after turning the ignition key 
to “START.”  
 
The 12-Volt auxiliary battery is located in the engine compartment. The jump 
starting procedure is the same as for other Lexus vehicles. 
 

 

Connect the positive jumper cable to the positive battery post. 

 

 

Connect the negative terminal to the ground nut. 

 

 

The high voltage HV battery pack cannot be jump started. 

 

Immobilizer & Anti-Theft Alarm 

The vehicle has an electronic key immobilizer system and anti-theft alarm as 
standard equipment.  The vehicle may only be started with a learned 
immobilizer coded key. 
 
To disarm the Anti-Theft Alarm: 

 

Unlock the door using an ignition key or wireless remote control. 

 

 

Turn the ignition switch on.
