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. Braking in Emergencies With anti-lock, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking. Traction Control System (TCS) Your vehicle may have a traction control system 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 works the front brakes and reduces engine power to limit wheel spin. You may feel or hear the system working, but this is normal. If your vehicle is in cruise control when the traction control system begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may reengage the crake contro!. See 'Cruise Control" under Turn Signal/Muitifunction Lever on page 3-7. 4-9 As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordincjy. 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 vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes.
