Recreational Vehicle Towing
Recreational vehicle towing means towing
the vehicle behind another vehicle–such as
behind a motor home. The two most
common types of recreational vehicle
towing are known as dinghy towing and
dolly towing. Dinghy towing is towing the
vehicle with all four wheels on the ground.
Dolly towing is towing the vehicle with two
wheels on the ground and two wheels up
on a device known as a dolly.
Before recreational vehicle towing, consider:
.Before towing the vehicle, become
familiar with the local laws that apply to
recreational vehicle towing. These laws
may vary by region.
.The towing capacity of the towing
vehicle. Be sure to read the tow vehicle
manufacturer's recommendations.
.How far the vehicle will be towed. Some
vehicles have restrictions on how far and
how long they can be towed.
.The proper towing equipment. See your
dealer or trailering professional for
additional advice and equipment
recommendations.
.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
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 that will be towed and secure it to the towing vehicle.
2. Put the vehicle in N (Neutral).
3. Shut engine off (vehicle will remain in accessory mode). 4. Disconnect the negative (-) terminal
connector from the 12-volt battery.
5. Close the hood of the vehicle.
Caution
If the vehicle is towed without
performing each of the steps listed under
“Dinghy Towing,” the automatic
transmission could be damaged. Be sure
to follow all steps of the dinghy towing
procedure prior to and after towing the
vehicle.
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. Shift the vehicle to P (Park).
2. Reconnect the negative (-) terminal connector to the 12-volt battery.
3. Start the engine and let it idle for more than three minutes before driving the
vehicle.

Vehicle Care 313
Caution
Too much or too little fluid can damage
the transmission. Be sure that the
transmission fluid is at the proper level
before towing with all four wheels on the
ground.
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 a vehicle from the front with the
rear wheels on the ground:1. Put the front wheels on a dolly.
2. Move the shift lever to P (Park). See Shifting Into Park 0206.
3. Set the parking brake.
4. Secure the vehicle to the dolly.
5. Follow the dolly manufacturer's instructions for preparing the vehicle and
dolly for towing.
6. Release the parking brake.
7. Turn off the vehicle.
8. Disconnect the negative (-) terminal connector from the 12-volt battery. 9. Close the hood of the vehicle.

Vehicle Care 321
Use the following guidelines for proper floor
mat usage.
.The original equipment floor mats were
designed for your vehicle. If the floor
mats need replacing, it is recommended
that GM certified floor mats be
purchased. Non-GM floor mats may not
fit properly and may interfere with the
accelerator or brake pedal. Always check
that the floor mats do not interfere with
the pedals.
.Do not use a floor mat if the vehicle is
not equipped with a floor mat retainer on
the driver side floor.
.Use the floor mat with the correct side
up. Do not turn it over.
.Do not place anything on top of the
driver side floor mat.
.Use only a single floor mat on the
driver side.
.Do not place one floor mat on top of
another.
Button Retainer
Some vehicles have floor mats with a
button-type retainer.
Removing and Replacing the Floor Mat1. Pull up on the rear of the mat to unlock and remove.
2. Reinstall the floor mat by lining up the floor mat opening over the carpet
retainer and snapping into position.
3. Make sure the floor mat is properly secured. Verify the floor mat does not
interfere with the pedals.
Cleaning Rubber Floor Mats (All-Weather
Mats and Floor Liners)
{Warning
Do not use cleaners that contain silicone,
wax-based products, or cleaners that
increase gloss on rubber floor mats/liners.
These cleaners can permanently change
the appearance and feel of the rubber
and can make the floor mats/liners
slippery. Your foot could slip while
operating the vehicle, and you could lose
control, resulting in a crash. You or
others could be injured.
Use a soft cloth and/or a brush dampened
with water to remove dust and loose dirt.
For more thorough cleaning, use a mild soap
solution.

Customer Satisfaction Procedure
Your satisfaction and goodwill are important
to your dealer and to Chevrolet. Normally,
any concerns with the sales transaction or
the operation of the vehicle will be resolved
by your dealer's sales or service
departments. Sometimes, however, despite
the best intentions of all concerned,
misunderstandings can occur. If your concern
has not been resolved to your satisfaction,
the following steps should be taken:
STEP ONE : Discuss your concern with a
member of dealership management.
Normally, concerns can be quickly resolved
at that level. If the matter has already been
reviewed with the sales, service, or parts
manager, contact the owner of your
dealership or the general manager.
STEP TWO : If after contacting a member of
dealership management, it appears your
concern cannot be resolved by your
dealership without further help, in the U.S.,
call the Chevrolet Customer Assistance
Center at 1-800-222-1020. In Canada, call
General Motors of Canada Customer Care
Centre at 1-800-263-3777 (English),
or 1-800-263-7854 (French).

Vehicle Data Recording and
Privacy
The vehicle has a number of computers that
record information about the vehicle’s
performance and how it is driven or used.
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 or to help GM improve
safety or features. 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.
Cybersecurity
GM collects information about the use of
your vehicle including operational and safety
related information. We collect this
information to provide, evaluate, improve,
and troubleshoot our products and services
and to develop new products and services.
The protection of vehicle electronics systems
and customer data from unauthorized
outside electronic access or control is
important to GM. GM maintains appropriate
security standards, practices, guidelines and
controls aimed at defending the vehicle and
the vehicle service ecosystem against
unauthorized electronic access, detecting
possible malicious activity in related
networks, and responding to suspected
cybersecurity incidents in a timely,
coordinated and effective manner. Security
incidents could impact your safety or
compromise your private data. To minimize
security risks, please do not connect your
vehicle electronic systems to unauthorized
devices or connect your vehicle to any
unknown or untrusted networks (such as
Bluetooth, WIFI or similar technology). In

348 Customer Information
the event you suspect any security incident
impacting your data or the safe operation of
your vehicle, please stop operating your
vehicle and contact your dealer.
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.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur. Note
EDR data are recorded by your vehicle only
if a non-trivial crash situation occurs; no
data are recorded by the EDR under normal
driving conditions and no personal data
(e.g., name, gender, age, and crash location)
are recorded. However, other parties, such
as law enforcement, could combine the EDR
data with the type of personally identifying
data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer, other parties, such
as law enforcement, that have the special
equipment, can read the information if they
have access to the vehicle or the EDR.
GM will not access these data or share it
with others except: with the consent of the
vehicle owner or, if the vehicle is leased,
with the consent of the lessee; in response
to an official request by police or similar
government office; as part of GM's defense
of litigation through the discovery process;
or, as required by law. Data that GM collects
or receives may also be used for GM
research needs or may be made available to
others for research purposes, where a need
is shown and the data is not tied to a
specific vehicle or vehicle owner.
OnStar
If the vehicle is equipped with OnStar and
has an active service plan, additional data
may be collected and transmitted through
the OnStar system. This includes information
about the vehicle’s operation; collisions
involving the vehicle; the use of the vehicle
and its features, including infotainment; and
the location and approximate GPS speed of
the vehicle. Refer to the OnStar Terms and
Conditions and Privacy Statement on the
OnStar website.
See
OnStar Additional Information 0350.
Infotainment System
If the vehicle is equipped with a navigation
system as part of the infotainment system,
use of the system may result in the storage
of destinations, addresses, telephone
numbers, and other trip information. See the
infotainment section for information on
stored data and for deletion instructions.
