Your Driving and the Road
If you decide you can go down a hill safely, then try to keep your vehicle
headed straight down, and use a low gear. This way, engine drag can help
your brakes and they won't have to do all the work. Descend slowly, keeping
your vehicle under control at all times.
A
Heavy braking when going down a hill can cause your brakes to
overheat and fade. This could cause loss of control and a serious
accident. Apply the brakes lightly when descending a hill and use a
low gear to keep vehicle speed und
1
control.
Q: Are there some things I should not do when driving down a hill?
A: Yes! These are important because if you ignore them you could lose
control and have a serious accident.
When driving downhill, avoid turns that take you across the incline of the
hill. A hill that's not too steep
to drive down may be too steep to drive
across. You could roll over i f you don't drive straight down.
Never go downhill with the transmission in N (Neutral), or with the clutch
pedal depressed in a manual shift. This is called "free-wheeling." Your
brakes will have to do all the work and could overheat and fade.
Avoid braking so hard that you lock the wheels when going downhill.
If
your front wheels are locked, you can't steer your vehicle. If your wheels
lock up during downhill braking, you may feel the vehicle starting to slide
sideways. To regain your direction, just ease
off the brakes and steer
to
keep the front of the vehicle pointing straight downhill.
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.
*
Stop your vehicle by applying the regular brakes. Apply the parking
brake.
Shift to P (Park) (or to N (Neutral) with the manual transmission) and,
while still braking, restart the engine.
Shift back to a low gear, release the parking brake, and drive straight
down.

If the engine won't start, get out and get help.
