A8110BE.book 15 ページ Starting and operating 7-15 Rear viscous limited slip differential (LSD) (if equipped) Power steering Braking Braking tips Never start the engine while a tire on one side is jacked up, as the vehicle may move. If one rear tire is spinning in mud, avoid continued spinning at high speed as this could adversely affect the LSD. If a different size rear tire is temporarily used (as in an emergency), it will adversely affect the LSD. Always replace it with a regular size tire as soon as possible. The LSD provides optimum distribution of power according to the difference in revolutions between the right and left rear wheels that may be caused by certain driving conditions, thereby improving driving stability on snow-covered, muddy or other slippery roads. Do not hold the steering wheel at the fully locked position left or right for more than five seconds. This may damage the power steering pump. The power steering system operates only when the engine is running. If you lose power steering assist because the engine stops or the system fails to function, you can steer but it will take much more effort. Never rest your foot on the brake pedal while driving. This can cause dangerous overheating of the brakes and needless wear on the brake pads and linings. When the brakes get wet When driving in rain or after washing the vehicle, the brakes may get wet. As a result, brake stopping distance will be longer. To dry the brakes, drive the vehicle at a safe speed while lightly depressing the brake pedal to heat up the brakes. Use of engine braking Remember to make use of engine braking in addition to foot braking. When descending a grade, if only the foot brake is used, the brakes may start working improperly because of brake fluid overheating, caused by overheated brake pads. To help prevent this, shift into a lower gear to get stronger engine braking. Braking when a tire is punctured Do not depress the brake pedal suddenly - CONTINUED - NOTE Right after the engine has been started and before it has warmed up, you may hear a noise coming from areas adjacent to the power steering pump which is located at the right-front area of the engine compartment. This noise is normal. It does not indicate power steering system trouble. 7
