Malfunction Indicator Lamp, Brake System Indicator To check if they are set, turn the ignition switch to the ON (II) position (set the power mode to ON, on models with keyless access system), without starting the engine. The malfunction indicator lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks five times, the readiness codes are not set. If possible, do not take your vehicle for an emissions test until the readiness codes are set. Refer to Emissions Testing for more information (see page 590 ). U.S. Canada Brake System Indicator The brake system indicator normally comes on when you turn the ignition switch to the ON (II) position, and as a reminder to check the parking brake. It will stay on if you do not fully release the parking brake. : Models equipped with the keyless access system have an engine start/stop button instead of an ignition switch. ON Mode is the equivalent of ON (II). For more information, see pages 178 and 181 . If the brake system indicator comes on while driving, the brake fluid level is probably low. Press lightly on the brake pedal to see if it feels normal. If it does, check the brake fluid level the next time you stop at a service station (see page 519 ). You will also see a ''LOW BRAKE FLUID'' message on the multiinformation display. If the fluid level is low, take your vehicle to a dealer, and have the brake system inspected for leaks or worn brake pads. However, if the brake pedal does not feel normal, you should take immediate action. A problem in one part of the system's dual circuit design will still give you braking at two wheels. You will feel the brake pedal go down much farther before the vehicle begins to slow down, and you will have to press harder on the pedal. You will also see a ''CHECK BRAKE SYSTEM'' message on the multiinformation display when this indicator comes on. CONTINUED Taking Care of the Unexpected 561 2010 TL
