suspension hopping. This can cause damage to
the driveline or suspension components. Improper
driving technique is not covered by your vehicle

• Try to drive straight up the hill if at all possible. If
the path twists and turns, you might want to find
another route.
{ 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.
• 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.
• Sound the horn as you approach the top of the hill
to let opposing traffic know you are there.
• Use your headlamps even during the day. They
make you more visible to oncoming traffic.
{ CAUTION:
Driving to the top (crest) of a hill at full speed
can cause an accident. There could be a
drop-off, embankment, cliff, or even another
vehicle. You could be seriously injured or
killed. As you near the top of a hill, slow down
and stay alert.
