(4WD) ● When cruising at highway speeds, it is more economical to use the air conditioner and leave the windows closed to reduce drag. ● Use 4H or 4L position only when necessary. Four-wheel drive operation lowers fuel economy. USING FOUR WHEEL DRIVE ● Do not leave the transfer control lever in the N (Neutral) position. Otherwise, the vehicle could roll unexpectedly even if the manual transmission is in any gear or the automatic transmission is in the P (Park) position. This could result in serious personal injury or property damage. ● Failure to engage the transfer control lever in 2H, 4H or 4L could result in the vehicle moving unexpectedly, which could cause serious personal injury or property damage. WSD0067 To move the transfer case lever: : Push down on the lever to shift : Shift without pushing down on the lever CAUTION Do not drive on dry hard surface roads in four-wheel drive. Driving on dry hard surfaces in 4H or 4L may cause unnecessary noise, tire wear, and increased fuel consumption. NISSAN recommends driving in the 2H position under these conditions. 2H - (2WD, high range) Only the rear wheels are driven. Use for driving under the same conditions as standard 2WD vehicles or state dynamometer I/M testing. 4H - (4WD, high range) Four wheels are driven. Use when driving on roads where it is difficult to TRANSFER CASE SHIFTING PROCEDURES WARNING ● When parking always make sure the transfer control lever is in the 2H, 4H or 4L position and the parking brake is applied. 5-22 Starting and driving
