Driving and Operating If the vehicle stalls on a hill: 1. Apply the brakes to stop the vehicle, and then apply the parking brake. 2. Shift into P (Park) for an automatic transmission or 1 (First) for a manual transmission and then restart the engine... 9-9 The vehicle can roll backward quickly and you could lose control. If driving downhill when the vehicle stalls, shift to a lower gear, release the parking brake, and drive straight down the hill. . . incline puts more weight on the downhill wheels which could cause a downhill slide or a rollover. Surface conditions can be a problem. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it - a rock, a rut, etc. - and roll over. Hidden obstacles can make the steepness of the incline more severe. If a rock is driven across with the uphill wheels, or if the downhill wheels drop into a rut or depression, the vehicle can tilt even more. If an incline must be driven across, and the vehicle starts to slide, turn downhill. This should help straighten out the vehicle and prevent the side slipping. If driving uphill when the vehicle stalls, shift to R (Reverse), release the parking brake, and back straight down. Never try to turn the vehicle around. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over. If you cannot make it up the hill, back straight down the hill. Never back down a hill in N (Neutral) using only the brake. 3. If the vehicle cannot be restarted after stalling, set the parking brake, shift an automatic transmission into P (Park) or a manual transmission into 1 (First), and turn the vehicle off. 3.1. Leave the vehicle and seek help. 3.2. Stay clear of the path the vehicle would take if it rolled downhill. . . . . . . Avoid turns that take the vehicle across the incline of the hill. A hill that can be driven straight up or down might be too steep to drive across. Driving across an
