Things not to do when driving down
a hill:
• When driving downhill, avoid turns
that take you across the incline of
the hill. A hill that is not too steep
to drive down might be too steep
to drive across. The vehicle could
roll over.
• Never go downhill with the
transmission in N (Neutral), called
free-wheeling. The brakes will
have to do all the work and could
overheat and fade.
Vehicles are much more likely to
stall when going uphill, but if it
happens when going downhill:
1. Stop the vehicle by applying the
regular brakes and apply the
parking brake.
2. Shift to P (Park) and, while still
braking, restart the engine.
3. Shift back to a low gear, release
the parking brake, and drive
straight down.
4. If the engine will not start, get
out and get help.
Driving Across an Incline
An off-road trail will probably go
across the incline of a hill. To decide
whether to try to drive across the
incline, consider the following:
{ CAUTION
Driving across an incline that is
too steep will make your vehicle
roll over. You could be seriously
injured or killed. If you have any
doubt about the steepness of the
incline, do not drive across it. Find
another route instead.
• A hill that can be driven straight
up or down might be too steep to
drive across. When going straight
up or down a hill, the length of the
wheel base — the distance from
the front wheels to the rear
wheels — reduces the likelihood
the vehicle will tumble end over
end. But when driving across
an incline, the narrower track
width — the distance between the
left and right wheels — might not
prevent the vehicle from tilting
and rolling over. Driving across an
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 even
worse. If you drive across a rock
with the uphill wheels, or if the
downhill wheels drop into a rut or
depression, the vehicle can tilt
even more.
For these reasons, carefully consider
whether to try to drive across an
incline. Just because the trail goes
across the incline does not mean you
have to drive it. The last vehicle to try
it might have rolled over.
