.Whether the vehicle is ready to
be towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Caution
Use of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle.
Dinghy Towing
These vehicles may be dinghy
towed from the front. These vehicles
can also be towed by placing them
on a platform trailer with all four
wheels off the ground. Also see the
information on dolly towing later in
this section.
For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be towed and secure it to the
towing vehicle.
2. Start the vehicle.
3. Shift the transmission to N (Neutral).
4. Put the vehicle into ACCESSORY Mode by
pressing ENGINE START/
STOP one time without the brake pedal applied. An amber
light will appear in the button
when in ACCESSORY Mode.
See
Ignition Positions 0192.
The chime will ring
continuously for 30 minutes.
Leave the transmission in
N (Neutral).
5. Turn off all accessories that are not needed.
It is required to charge the battery of
the towed vehicle during
recreational vehicle towing.
Caution
If the vehicle is towed without
performing each of the steps
listed under “Dinghy Towing,” the
automatic transmission and AWD
system could be damaged. Be
sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.

Vehicle Care 337
Caution
If 105 km/h (65 mph) is exceeded
while towing the vehicle, it could
be damaged. Never exceed
105 km/h (65 mph) while towing
the vehicle.
Once the destination is reached: 1. Set the parking brake.
2. Shift the transmission to P (Park).
3. Turn the vehicle off.
4. Start the engine and let it idle for more than three minutes
before driving the vehicle.
Caution
Do not tow a vehicle with the front
drive wheels on the ground if one
of the front tires is a compact
spare tire. Towing with two
different tire sizes on the front of
the vehicle can cause severe
damage to the transmission.
Dolly Towing
To tow the vehicle from the front
with two wheels on the ground:
1. Put the front wheels on a dolly.
2. Shift the transmission to P (Park).
3. Set the parking brake.
4. Clamp the steering wheel in a straight-ahead position with a
clamping device designed for
towing.
5. Turn the vehicle off.
6. Secure the vehicle to the dolly. 7. Release the parking brake.

Managing the Vehicle Damage
Repair Process
In the event that the vehicle requires
damage repairs, GM recommends
that you take an active role in its
repair. If you have a pre-determined
repair facility of choice, take the
vehicle there, or have it towed there.
Specify to the facility that any
required replacement collision parts
be original equipment parts, either
new Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be covered by
the GM vehicle warranty.
Insurance pays the bill for the repair,
but you must live with the repair.
Depending on your policy limits,
your insurance company may
initially value the repair using
aftermarket parts. Discuss this with the repair professional, and insist on
Genuine GM parts. Remember,
if the vehicle is leased, you may be
obligated to have the vehicle
repaired with Genuine GM parts,
even if your insurance coverage
does not pay the full cost.
If another party's insurance
company is paying for the repairs,
you are not obligated to accept a
repair valuation based on that
insurance company's collision policy
repair limits, as you have no
contractual limits with that company.
In such cases, you can have control
of the repair and parts choices as
long as the cost stays within
reasonable limits.

Recording and
Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven. For example, the
vehicle uses computer modules to
monitor and control engine and
transmission performance, to
monitor the conditions for airbag
deployment and deploy them in a
crash, and, if equipped, to provide
antilock braking to help the driver
control the vehicle. These modules
may store data to help the dealer
technician service the vehicle.
Some modules may also store data
about how the vehicle is operated,
such as rate of fuel consumption or
average speed. These modules may
retain personal preferences, such as
radio presets, seat positions, and
temperature settings.
Event Data Recorders
This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an air
bag deployment or hitting a road
obstacle, data that will assist in
understanding how a vehicle’s
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:
.How various systems in your
vehicle were operating;
. Whether or not the driver and
passenger safety belts were
buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/
or brake pedal; and,
. How fast the vehicle was
traveling.
