TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are oper-
able, disabled vehicles may also be towed as described under “Recreational Towing” in the “Starting And Operating” section.

Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow bars
and other equipment designed for this purpose,
following equipment manufacturer’s instructions.
Use of safety chains is mandatory. Attach a tow
bar or other towing device to main structural
members of the vehicle, not to bumpers or associ -
ated brackets. State and local laws regarding vehi -
cles under tow must be observed.

If you must use the accessories (wipers,
defrosters, etc.) while being towed, the igni -
tion must be in the ON/RUN position, not the
ACC position. If the vehicle's battery is discharged, refer to
“Manual Park Release” in this chapter for
instructions on shifting the automatic trans
-
mission out of PARK in order to move the
vehicle.

ENHANCED ACCIDENT
RESPONSE SYSTEM (EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
Please refer to “Occupant Restraint
Systems” in “Safety” for further information
on the Enhanced Accident Response System
(EARS) function.
EVENT DATA RECORDER
(EDR)
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record data that will assist in
understanding how a vehicle’s systems
performed under certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle.
Please refer to “Occupant Restraint
Systems” in “Safety” for further information
on the Event Data Recorder (EDR).
The brake and steering power assist
systems will not function while the
vehicle is being towed. You will, there-
fore, need to apply more force on the
brake pedal and steering wheel. Do not
use flexible ropes when towing, and
avoid jerky movements. Do not start the
engine while towing the car. Before
tightening the ring, clean the threaded
housing thoroughly. Make sure that the
ring is fully screwed into the housing
before towing the car.
CAUTION!
The tow eye must only be used for road -
side emergencies. Use with an appro-
priate device in accordance with highway
code (a rigid bar) to maneuver the
vehicle in preparation for transport via a
tow truck.
The tow eye must not be used to move
the vehicle off the road or where there
are obstacles.
Do not use the tow eyes for tow truck
hookup or highway towing.
WARNING! (Continued)
Do not use the tow eye to free a stuck
vehicle. Refer to the “Freeing A Stuck
Vehicle” section for further information.
Please refer to the “Towing A Disabled
Vehicle” section for detailed
instructions. Damage to your vehicle
may occur if these guidelines are not
followed.
