GAUGES, METERS AND SERVICE REMINDER INDICATORS w273 If you get out from the vehicle, having a smart key when the ignition switch is in the "ACC" or "ON" position and the selector lever is in a position other than "P", the master warning light flashes, a beep sounds inside the vehicle and the above message appears. When you shift the selector lever to the "P" position or start driving, the beeping stops sounding, the above message turns off. In addition to the above condition, if the smart key system does not detect a smart key in the vehicle, "Shift to P Range" and "Key is not Detected" appear alternately. w275 If the smart key system determines that the battery voltage is low (2V to 3V) when the ignition is turned off more than 20 minutes after turned on, the master warning light flashes, a warning tone sounds and the above message appears for 5 seconds. If the above message appears, the battery needs to be replaced. Although you can replace the battery referring to "Replacing the battery (Type A)" on page 42, we recommend you have it replaced by your Lexus dealer as it is easy to be scratched. w274 If the smart key system determines that the electronic code of the detected key does not correspond to the registered ID when you push the ignition switch or lock button on the outside door handle, the master warning light flashes, a warning tone sounds and the above message appears for 5 seconds. w276 The above message appears when the high mode in the electronically modulated air suspension is selected. However, if the system fails, the master warning light comes on, a warning tone also sounds and the above message appears. Although it is no problem to continue driving, have your vehicle checked by your Lexus dealer as soon as possible. 99
