Of course, traction is reduced when water, snow, ice, gravel, or other material is on the road. For safety, you will want to slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance will be longer and vehicle control more limited. While driving on a surface with reduced traction, try your best to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide. You may not realize the surface is slippery until your vehicle is skidding. Learn to recognize warning clues - such as enough water, ice, or packed snow on the road to make a mirrored surface - and slow down when you have any doubt. Remember: Any Antilock Brake System (ABS) helps avoid only the braking skid. Racing or Other Competitive Driving (XLR-V) See your warranty book before using your vehicle for racing or other competitive driving. Notice: If you use your vehicle for racing or other competitive driving, the engine may use more oil than it would with normal use. Low oil levels can damage the engine. Be sure to check the oil level often during racing or other competitive driving and keep the level at or near 2 quarts (2 L) above the upper mark that shows the proper operating range on the engine oil dipstick. For information on how to add oil, see Engine Oil on page 6-16. After the competitive driving, remove excess oil so that the level on the dipstick is not above the upper mark that shows the proper operating range. 5-13
