What is the security indicator light on a Lexus?

Understanding the Lexus Security Indicator Light
The security indicator light in a Lexus serves as an important visual cue for the status of the vehicle’s security system. Here’s what it means:
1. Functionality of the Security System:
– The Security Indicator Light illuminates to indicate that the security system is either working properly or to let you know that there is a fault in the system.
– If the Security Indicator Light is flashing with the key out of the ignition lock and accessory position, this is a normal sign that the alarm and the immobilizer system is active.
– While starting the car or key in the “run” position, the security lamp should illuminate briefly then go out. This is a bulb check and is also normal.
2. Troubleshooting:
– If the Security Indicator Light is on steady with the key in the “run” position and the vehicle won’t start, there could be a fault with the system. In this case, trying a different key to see if it starts the vehicle is recommended. If it starts, the key is faulty or the system has a problem with that key.
– A lit security light indicates a problem in the car’s anti-theft immobilizer system. Trying a new key or seeking assistance from a mechanic is advised.
3. Deactivation and Troubleshooting:
– If the Security Indicator Light keeps blinking and prevents driving the car, following the instructions in the owner’s manual to deactivate or stop the alarm may be necessary.
– It’s important to note that the security light always includes a picture of a car and a key and usually lights up red or gold.
In summary, the security indicator light in a Lexus serves as a crucial indicator of the security system’s status, and its behavior can provide valuable insights into the system’s functionality or potential faults.
