If you do not have anti-lock, use a "squeeze" braking technique. This will give you maximum braking while maintaining steering control. You can do this by pushing on the brake pedal with steadily increasing pressure. In an emergency, you will probably want to squeeze the brakes hard without locking the wheels. If you hear or feel the wheels sliding, ease off the brake pedal. This will help you retain steering control. If you do have anti-lock, it is different. See "Anti-Lock Brake System" in this section. In many emergencies, steering can help you more than even the very best braking. This light will come on when your Enhanced Traction System is limiting wheel spin. See Enhanced Traction System Active Light on page 3-31. You may feel or hear the system working, but this is normal. If your vehicle is in cruise control when the enhanced traction system begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may re-engage the cruise control. See Cruise Control on page 3-10. The Enhanced Traction System operates in all transaxle shift lever positions. But the system can upshift the transaxle only as high as the shift lever position you've chosen, so you should use the lower gears only when necessary. See Automatic Transaxle Operation on page 2-22. Enhanced Traction System (ETS) Your vehicle may have 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. 4-9
