Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps: {CAUTION: Turning or driving across steep hills can be dangerous. You could lose traction, slide sideways, and possibly roll over. You could be seriously injured or killed. When driving up hills, always try to go straight up. • Use transmission and transfer case low gear and get a firm grip on the steering wheel. • Get a smooth start up the hill and try to maintain your speed. Do not use more power than you need, because you do not want the wheels to start spinning or sliding. • Let the traction system work to control any wheel slippage. The traction control system allows for moderate wheel spin with some capability to dig in and power up the hill. • Try to drive straight up the hill if at all possible. If the path twists and turns, you might want to find another route. • Do not continue if the vehicle shudders or exhibits suspension hopping. This can cause damage to the driveline or suspension components. Improper driving technique is not covered by your vehicle warranty. • Ease up on your speed as you approach the top of the hill. • Attach a flag to the vehicle to make you more visible to approaching traffic on trails or hills. 4-24
