The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. Remember: Anti-lock doesn't change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get close to the vehicle in too front of you, you won't have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Using Anti-Lock Don't pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may feel a slight brake pedal pulsation or notice some noise, but this is normal, Enhanced Traction System If your vehicle has the optional four-speed automatic transaxle, it also has an Enhanced Traction System (ETS) that limits wheel spin.This is especially useful in slippery road conditions.The system operates only if it senses that one or both of the front wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power and may also upshift the transaxle to limit wheel spin. You can steer aroundthe obstacle while braking hard. As you brake, your computer keeps receiving updates on wheel speed and controlsbraking pressure accordingly. 4-8
