Driving Uphill
Once you decide it is safe to drive up the hill:
• 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
speed. Not using more power than needed can
avoid spinning the wheels 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.
• 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 the vehicle
warranty.
{ 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.
• Try to drive straight up the hill if at all possible.
If the path twists and turns, you might want to
find another route.
• Ease up on the speed as you approach the top of
the hill.
• Attach a flag to the vehicle to be more visible to
approaching traffic on trails or hills.
• Sound the horn as you approach the top of the hill
to let opposing traffic know you are there.
• Use headlamps even during the day to make the
vehicle more visible to oncoming traffic.
