As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly. 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 too close to the vehicle in front of you, you won't have time to apply your brakes if that vehiclesuddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. LOW TRAC This light will come on when your Enhanced Traction System is limiting wheel spin. See "Enhanced Traction System Active Light" in the Index. You may feel orhear the system working, but this is normal. Using Anti-Lock Don't pump the brakes. Just hold the brake pedal down and let anti-lock workfor you. You may feel the system working, or you may notice some noise, but thisis normal. The Enhanced Traction System operates in all transaxle shift leverpositions. But the system can upshift the transaxle only ashigh as the shift lever position you've chosen, so you should use the lower gears only when necessary. See "Automatic Transaxle" in the Index. Enhanced Traction System(If Equipped) 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. Thesystem operates only if it senses that one orboth of the front wheels are spinning or beginning to lose traction. When this happens, the system reduces enginepower and may also upshift the transaxle to limit wheel spin. 4-9
