228 Operation
Driving instructions
Read this chapter carefully before you be-
gin off-road travel.
Familiarize yourself with the vehicle char-
acteristics and gear changing before you
attempt any difficult terrain off-road driv-
ing. We recommend that you start out with
easy off-road travel.Special driving features for off-road
driving
The following driving features are available
for specific kind of operation:
ABS (page 80)
ESP (page 84)
4-ETS (page 83)
Differential lock (page 159)
Transfer case (page 157)
Off-road driving rules
Engage the transfer case in position
LOW before driving under off-road con-
ditions (
page 157).
If necessary activate differential locks
(
page 161).
The ABS, BAS and ESP are switched off
automatically when the differential
locks are activated.
Fasten items being carried as securely
as possible (
page 192).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you
use only the brake.
Sand, dirt, mud and other material having
friction property can cause exceptional wear
and tear as well as brake failure.
Have the brakes checked for dirt build-up
and cleaned. There is otherwise a risk that
full braking power may not be available in an
emergency.i
Whenever driving in off-road mode, we
recommend:
Keeping doors, tailgate, windows
and tilt/sliding sunroof closed.
Switching cruise control off.
!
Observe the following during off-road
driving:
Adjust vehicle speed to condition of
terrain. The more uneven, rutty, and
steeper the terrain, the lower the
speed should be. Drive through wa-
ter slowly at an even speed, avoid-
ing a bow wave.
Be especially careful when driving
in unknown territory. It may be nec-
essary to get out of the vehicle and
scout the path you intend to take.
Watch out for obstacles, such as
rocks, holes, tree stumps, and ruts.
