Off-Road Recovery
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have
to act fast, steer quickly, and
just
as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving at
all times and wear safety belts properly. You may
find sometime that your right wheels have
dropped off
the edge of a road onto the shoulder while
you’re driving.

edge of paved surface
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the accelerator and then,
if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
You can
turn the steering wheel up to one-quarter turn
until the right front tire contacts the pavement edge. Then
turn your steering wheel to go straight down the roadway.

0 As you are backing down the hill, put your left hand
on the steering wheel at the 12 o’clock position. This
way, you’ll be able to
tell if your wheels are straight
and maneuver as you back down. It’s best that you
back down the
hill with your wheels straight rather
than
in the left or right direction. Turning the wheel
too far to the left or right will increase the possibility
of a rollover.
Here are some things you
must not do if you stall, or are
about to stall, when going up a hill.
0 Never attempt to prevent a stall by shifting into
NEUTRAL
(N) (or depressing the clutch, if you
have a manual transmission) to “rev-up” the engine
and regain forward momentum. This won’t work.
Your vehicle will roll backwards very quickly and
you could
go out of control.
Instead, apply the regular brake to stop the
vehicle. Then apply
the parking brake. Shift to
REVERSE (R), release the parking brake, and
slowly back straight down.
0 Never attempt to turn around if you are about to stall
when going up a hill. If the hill is steep enough
to
stall your vehicle, it’s steep enough to cause you to
roll over if you turn around.
If you can’t make it up
the hill, you must back straight down the hill.
@ Suppose, after stalling, I try to back down the hill
and decide
I just can’t do it. What should I do?
A: Set the parking brake, put your transmission in
PARK (P) (or the manual transmission in FIRST (1))
and turn off the engine. Leave the vehicle and go get
some help. Exit on the uphill side and stay clear
of
the path the vehicle would take if it rolled downhill.
Do not shift the transfer case to NEUTRAL (N)
when you leave the vehicle. Leave it in I ne gel
Shifting the transfer case to NEUTR
I (N) can
cause your vehicle to roll even if the transmission
is in PARK (P) (or, if you have the manual
transmission, even if you’re in gear). This is
because the
NEUTRAL (N) position on the
transfer case overrides the transmission.
If you
are going to leave your vehicle, set the parking
brake and shift the transmission to
PARK (P)
(or, put your manual transmission in FIRST (1)).
But do not shift the transfer case to the
NEUTRAL
(N) position. Leave the transfer case
in the
2 Wheel, 4 High or 4 Low position.

Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
NOTICE:
Raising your vehicle with the jack improperly
positioned will damage the vehicle or may allow
the vehicle to
fall off the jack. Be sure to fit the
jack lift head into the proper location before
raising your vehicle.
