Section 3
Here are some other things to
consider as you approach a hill.
• Is there a constant incline, or
does the hill get sharply steeper
in places?
• Is there good traction on the
hillside, or will the surface
cause tyre slipping?
• Is there a straight path up or
down the hill so you won’t
have to make turning
manoeuvres?
• Are there obstructions on the
hill that can block your path
(boulders, trees, logs or ruts)?
• What’s beyond the hill? Is there
a cliff, an embankment, a drop-
off, a fence? Get out and walk
the hill if you don’t know. It’s
the smart way to find out.
• Is the hill simply too rough?
Steep hills often have ruts, gul-
lies, troughs and exposed rocks
because they are more suscep-
tible to the effects of erosion.
DRIVING UP-HILL
Once you decide you can safely
drive up the hill, you need to take
some special steps.
• Use low transmission and trans-
fer case gears and get a firm
grip on the steering wheel.
• Get a smooth start up the hill
and try to maintain your speed.
Don’t use more power than
you need, because you don’t
want your wheels to start spin-
ning or sliding.
• Let the traction control system
work to control wheel slippage.
The traction control system is
designed to allow moderate
wheel spin while maintaining
some capability of digging in
and powering up the hill.
