Q:
Am I likely to stall when going downhill?
A:
It’s much more likely to happen going uphill. But if
it happens going downhill, here’s what to do.
D Stop your vehicle by applying the regular brakes.
Apply the parking brake.
D Shift to PARK (P) and, while still braking, restart
the engine.
D Shift back to a low gear, release the parking brake,
and drive straight down.
D If the engine won’t start, get out and get help.
Driving Across an Incline
Sooner or later, an off
-
road trail will probably go across
the incline of a hill. If this happens, you have to decide
whether to try to drive across the incline. Here are some
things to consider:
D A hill that can be driven straight up or down may
be too steep to drive across. When you go 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 you drive across
an incline, the much more narrow track width
(the distance between the left and right wheels) may
not prevent the vehicle from tilting and rolling over.
Also, driving across an incline puts more weight on
the downhill wheels. This could cause a downhill
slide or a rollover.
D Surface conditions can be a problem when you drive
across a hill. Loose gravel, muddy spots, or even wet
grass can cause your 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.
D 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, your vehicle can tilt even more.
For reasons like these, you need to decide carefully
whether to try to drive across an incline. Just because the
trail goes across the incline doesn’t mean you have to
drive it. The last vehicle to try it might have rolled over.
CAUTION:
Driving across an incline that’s 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, don’t drive
across it. Find another route instead.
