Brake System Indicator BRAKE SYSTEM INDICATOR DX models U.S. indicator shown If it comes on at any other time, it indicates a problem with the car's brake system. In most cases, the problem is a low fluid level in the brake fluid reservoir. 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 217 ). If the fluid level is low, take the car to your 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. Because of the brake system's dual-circuit design, a problem in one part of the system will still give you braking at two wheels. You will feel the brake pedal go down much farther before the car begins to slow down, and you will have to press harder on the pedal. The distance needed to stop will be much longer. Slow down by shifting to a lower gear, and pull to the side of the road when it is safe. Because of the longer distance needed to stop, it is hazardous to drive the car. You should have it towed, and repaired as soon as possible. (See Emergency Towing on page 283 .) If you must drive the car a short distance in this condition, drive slowly and cautiously. 276 Taking Care of the Unexpected
