vehicle can tow. If towing a trailer, the
tongue load must be added to the
GVW because the vehicle will be
carrying that weight, too. SeeVehicle
Load Limits 0188.
The trailer tongue (1) should weigh 10
to 15 percent of the total loaded
trailer weight (2).
After loading the trailer, weigh the
trailer and then the tongue,
separately, to see if the weights are
proper. If they are not, adjustments
might be made by moving some items
around in the trailer.
Total Weight on Your Vehicle's
Tires
Be sure the vehicle's tires are inflated
to the upper limit for cold tires. These
numbers can be found on the Tire and
Loading Information label. See Vehicle
Load Limits 0188. Make sure not to go
over the GVW limit for the vehicle,
including the weight of the trailer
tongue.
Trailer Towing (V6 Twin
Turbo)
The vehicle is neither designed nor
intended to tow a trailer.
Towing Equipment
(V6 Engine, Non Twin
Turbo)
Hitches
Use the correct hitch equipment. See
your dealer or a hitch dealer for
assistance.
. The rear bumper on the vehicle is
not intended for hitches. Do not
attach rental hitches or other bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
. Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If so, seal
the holes when the hitch is
removed. If the holes are not
sealed, dirt, water, and deadly
carbon monoxide (CO) from the
exhaust can get into the vehicle.
See Engine Exhaust 0199.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the safety
chains under the tongue of the trailer
to help prevent the tongue from
contacting the road if it becomes
separated from the hitch. Leave
enough slack so the rig can turn.
Never allow safety chains to drag on
the ground.
Trailer Brakes
Does the trailer have its own brakes?
State and local regulations may
require the trailer to have its own
braking system if loaded above a

certain threshold. Trailer brake
requirements vary from state to state.
Be sure to read and follow the
instructions for the trailer brakes so
they are installed, adjusted, and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If this is done, both
brake systems will not work well or
at all

Emission Inspection/Maintenance
testing. SeeMalfunction Indicator
Lamp (Check Engine Light) 0128.
A device connected to the DLC —
such as an aftermarket fleet or
driver-behavior tracking device —
may interfere with vehicle systems.
This could affect vehicle operation
and cause a crash. Such devices
may also access information stored
in the vehicle’s systems.
Caution
Some electrical equipment can
damage the vehicle or cause
components to not work and would
not be covered by the vehicle
warranty. Always check with your
dealer before adding electrical
equipment.
Add-on equipment can drain the
vehicle's 12-volt battery, even if the
vehicle is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see Servicing
the Airbag-Equipped Vehicle 086 and
Adding Equipment to the

Here are some important things to
consider before recreational vehicle
towing:
.What is the towing capacity of the
towing vehicle? Be sure to read the
tow vehicle manufacturer's
recommendations.
. What is the distance that will be
traveled? Some vehicles have
restrictions on how far and how
long they can tow.
. Is the proper towing equipment
going to be used? See your dealer
or trailering professional for
additional advice and equipment
recommendations.
. Is the vehicle ready to be towed?
Just as preparing the vehicle for a
long trip, make sure the vehicle is
prepared to be towed.Dinghy Towing
Caution
If the vehicle is towed with all four
wheels on the ground, the
drivetrain components could be
damaged. The repairs would not be
covered by the vehicle warranty. Do
not tow the vehicle with all four
wheels on the ground. The vehicle was not designed to be
towed with all four wheels on the
ground. If the vehicle must be towed,
a dolly should be used. See the
following information on dolly towing.
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.

338 SERVICE AND MAINTENANCE
additional maintenance items like
tires, brakes, batteries, and wiper
blades.
Caution
Damage caused by improper
maintenance can lead to costly
repairs and may not be covered by
the vehicle warranty. Maintenance
intervals, checks, inspections,
recommended fluids, and lubricants
are important to keep the vehicle in
good working condition.
Do not have chemical flushes that
are not approved by GM performed
on the vehicle. The use of flushes,
solvents, cleaners, or lubricants that
are not approved by GM could
damage the vehicle, requiring
expensive repairs that are not
covered by the vehicle warranty.
The Tire Rotation and Required
Services are the responsibility of the
vehicle owner. It is recommended to
have your dealer perform these
services every 12 000 km/7,500 mi. Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy, and
reduces vehicle emissions.
Because of the way people use
vehicles, maintenance needs vary.
There may need to be more frequent
checks and services. The Additional
Required Services - Normal are for
vehicles that:
.
Carry passengers and cargo within
recommended limits on the Tire
and Loading Information label. See
Vehicle Load Limits 0188.
. Are driven on reasonable road
surfaces within legal driving limits.
. Use the recommended fuel. See
Fuel 0242.
Refer to the information in the
Maintenance Schedule Additional
Required Services - Normal chart.
The Additional Required Services -
Severe are for vehicles that are:
. Mainly driven in heavy city traffic
in hot weather
. Mainly driven in hilly or
mountainous terrain .
Frequently towing a trailer
. Used for high speed or competitive
driving
. Used for taxi, police, or delivery
service
Refer to the information in the
Maintenance Schedule Additional
Required Services - Severe chart.
{Warning
Performing maintenance work can
be dangerous and can cause serious
injury. Perform maintenance work
only if the required information,
proper tools, and equipment are
available. If they are not, see your
dealer to have a trained technician
do the work. See Doing Your Own
Service Work 0254.
