yellowblue FIRST (1): This position gives you even more power but lower fuel economy than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won't shift into FIRST (1) until the vehicle is going slowly enough. If your vehicle is equipped with the tow/haul selector switch, you can use this feature to more efficiently tow or haul a heavy load. To select the tow/haul mode, press in on the switch. The Tow/Haul light on the instrument panel cluster will come on. To go back to normal operation, press the switch again. The indicator light on the instrument panel will go out. See "Tow/Haul Mode" in the Index for more information. NOTICE: If your rear wheels can't rotate, don't try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission. Also, if you stop when going uphill, don't hold your vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or shift into PARK (P) to hold your vehicle in position on a hill. Manual Transmission Operation 5-Speed This is your shift pattern. Tow/Haul Selector Switch (If Equipped) Your vehicle may be equipped with a tow/haul selector switch. This switch will be located on the floor console. 2-24
