2-4. Using other driving systems CAUTION n Caution while driving l Never shift the front-wheel drive control lever from H2 to H4 if the wheels are slipping. Stop the slipping or spinning before shifting. l For normal driving on dry and hard surface roads, use H2 position. Driving on dry and hard surface roads in H4 or L4 position may cause drive component oil leakage, seizure, or other problems resulting in an accident. Further, it may cause tire wear and increased fuel consumption. l Avoid turning suddenly in H4 or L4 position. If you do turn suddenly, the difference in turning speeds between the front and rear wheels may have a similar effect to braking, thus making driving difficult. l Securely shift the front-wheel drive control lever to H4 or L4. Otherwise, the transfer may disengage both the front and rear driveshafts from the powertrain and allow the vehicle to move regardless of the shift position. If this happens, the vehicle may be free to roll even if the automatic transmission is in P. 166
