Driving and Operating
203
When driving on hills:
.
Use a low gear and keep a firm grip on
the steering wheel.
.
Maintain a slow speed.
.
When possible, drive straight up or down
the hill.
.
Slow down when approaching the top of
the hill.
.
Use headlamps even during the day to
make the vehicle more visible.
{
Warning
Driving to the top of a hill at high speed
can cause a crash. 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.
.
Never go downhill forward or backward
with the transmission in N (Neutral). The
brakes could overheat and you could lose
control.
.
When driving down a hill, keep the
vehicle headed straight down. Use a low
gear because the engine will work with
the brakes to slow the vehicle and help
keep the vehicle under control.
{
Warning
Heavy braking when going down a hill
can cause your brakes to overheat and
fade. This could cause loss of control and
you or others could be injured or killed.
Apply the brakes lightly when descending
a hill and use a low gear to keep vehicle
speed under control.
If the vehicle stalls on a hill:
1. Apply the brakes to stop the vehicle, and
then apply the parking brake.
2. Shift into P (Park) and then restart the
engine.
.
If driving uphill when the vehicle
stalls, shift to R (Reverse), release the
parking brake, and back
straight down.
.
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 the
transmission into P (Park), 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 and potentially and
roll over.
