Driving and Operating

9-9

.

Never try to turn the vehicle
around. If the hill is steep
enough to stall the vehicle,
it is steep enough to cause
it to roll over.

.

If you cannot make it up the
hill, back straight down
the hill.

.

Never back down a hill in
N (Neutral) using only the
brake.

.

The vehicle can roll
backward quickly and you
could lose control.

.

If driving downhill when the
vehicle stalls, shift to a
lower gear, release the
parking brake, and drive
straight down the hill.

3. If the vehicle cannot be restarted

after stalling, set the parking
brake, shift an automatic
transmission into P (Park) or
a manual transmission into
1 (First), and turn the vehicle off.

3.1. Leave the vehicle and

seek help.

3.2. Stay clear of the path the

vehicle would take if it
rolled downhill.

.

Avoid turns that take the vehicle
across the incline of the hill.
A hill that can be driven straight
up or down might be too steep to
drive across. 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 more
severe. If a rock is driven across
with the uphill wheels, or if the
downhill wheels drop into a rut
or depression, the vehicle can tilt
even more.

.

If an incline must be driven
across, and the vehicle starts to
slide, turn downhill. This should
help straighten out the vehicle
and prevent the side slipping.

{

WARNING

Getting out of the vehicle on the
downhill side when stopped
across an incline is dangerous.
If the vehicle rolls over, you could
be crushed or killed. Always get
out on the uphill side of the
vehicle and stay well clear of the
rollover path.
