WARNING
Shifting a full‐time four‐wheel‐
drive vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the automatic
transmission is in P (Park) or the
manual transmission is in any
gear. You or others could be
injured. Make sure the parking
brake is firmly set before the
transfer case is shifted to
N (Neutral).
5. Shift the transfer case to
N (Neutral). See Four-Wheel
Drive on page 9‑46 for the
proper procedure to select the
N (Neutral) position for the
vehicle.
6. Release the parking brake only
after the vehicle being towed
is firmly attached to the tow
vehicle.
7. Make sure the ignition is in
ACC/ACCESSORY.
When towing the vehicle for
extended periods of time, start the
vehicle as often as possible to
prevent battery drain. This should
only be done when the tow vehicle
is parked.
After towing, see “Shifting Out of
NEUTRAL” under Four-Wheel Drive
on page 9‑46.

Notice: Dolly towing the
vehicle will damage drivetrain
components. Do not dolly tow the
