After towing the vehicle, you will
have to shift out of N (Neutral) in
order to drive. To shift out of
N (Neutral), do the following:
1. Set the parking brake and apply
the regular brake pedal.
2. Start a vehicle with an automatic
transmission in P (Park). Use
1 (First) for vehicles with a
manual transmission.
3. Shift the transmission to
N (Neutral), or press the clutch
pedal for vehicles with a manual
transmission.
4. Press the button for the desired
transfer case shift position
(Two-Wheel High, Four-Wheel
High, or Four-Wheel Low).
5. After the transfer case has
shifted out of N (Neutral), the
indicator light will go out.
6. Release the parking brake.
7. Shift the transmission to the
desired position.
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that
helps prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See
.
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
