Dodge 2012 Charger - Owner Manual - Manual (Page 488)

If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than
15 miles (24 km) for 5-speed transmission, or 30 miles
(48 km) for 8-speed transmission, tow with the rear
wheels OFF the ground (on a flatbed, or with the rear
wheels raised using a wheel lift and the transmission in
NEUTRAL).
CAUTION!
Failure to follow these towing methods can cause
severe transmission damage. Such damage is not
covered by the New Vehicle Limited Warranty.
Vehicles equipped with AWD can be towed with the
transmission in NEUTRAL and the rear wheels OFF the
ground with no limitation on speed or distance.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the OFF position. The only approved
method of towing without the ignition key is with a
flatbed truck. Proper towing equipment is necessary to
prevent damage to the vehicle.
