vehicle transmission is in PARK, NEUTRAL, or
REVERSE. The trailer spotter lights will turn off
when the vehicle transmission is placed in
DRIVE.
NOTE:
For vehicles shipped to or sold in the states of
California or Mississippi, the cargo, bed, and
mirror spotter lights will not work while the
vehicle is in motion. In every other state, the
cargo and mirror spotter lights will turn off when
the vehicle is in motion, but the bed light will
remain on. In all states, including California and
Mississippi, if a bed camera is deactivated, the
bed lights will turn back on.

If the key fob is unavailable or the vehicle's
battery is discharged, refer to ”Manual Park
Release” in this section for instructions on
shifting the transmission out of PARK for
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground

The towing distance must not exceed
30 miles (48 km) for 8–speed transmission.

15 miles (24 km) for 6–speed transmission.
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph

OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed, or with the front wheels
raised and the rear wheels on a towing dolly, or
(when using a suitable steering wheel stabilizer
to hold the front wheels in the straight position)
with the rear wheels raised and the front wheels
on the ground.

transfer case is operable, the vehicle may be
towed (in the forward direction, with ALL wheels
on the ground), IF the transfer case is in
NEUTRAL (N) and the transmission is in PARK.
Refer to “Recreational Towing” in “Starting And
Operating” for further information and detailed
instructions.
