Driving and Operating 287
After loading the trailer, separately weigh
the trailer and then the trailer tongue and
calculate the trailer load balance percentage
to see if the weights and distribution are
appropriate for your vehicle. If the trailer
weight is too high, it may be possible to
transfer some of the cargo into your vehicle.
If the trailer tongue weight is too high or
too low, it may be possible to rearrange
some of the cargo inside of the trailer.
Do not exceed the maximum allowable
tongue weight for your vehicle. Use the
shortest hitch extension available to position
the hitch ball closer to your vehicle. This will
help reduce the effect of the trailer tongue
weight on the trailer hitch and the rear axle.
If a cargo carrier is used in the trailer hitch
receiver, choose a carrier that positions the
load as close to the vehicle as possible.
Make sure the total weight, including the
carrier, is no more than half of the
maximum allowable tongue weight for the
vehicle or 227 kg (500 lb), whichever is less.Rear Gross Axle Weight Rating
(GAWR-RR)
The GAWR-RR is the total weight that can be
supported by the rear axle of the vehicle. Do
not exceed the GAWR-RR for the vehicle,
with the tow vehicle and trailer fully loaded
for the trip including the weight of the
trailer tongue. If using a weight-distributing
hitch, do not exceed the GAWR-RR after
applying the weight distribution spring bars.
The GAWR-RR for the vehicle is on the
Trailering Information Label.
Ask your dealer for trailering information or
assistance.
Towing Equipment
Hitches
{Warning
In order to avoid serious injury or
property damage, always follow the hitch
manufacturer's instructions when securing
your draw bar/coupling device to the
vehicle's hitch receiver.
Ensure that the draw bar/coupling device
is secured with a locking retainer pin or
other means such that rotation of the pin
or locking mechanism will not cause the
pin to back out or loosen during use.
Failure to correctly secure the draw bar/
coupling device to the receiver can result
in separation of the hitch/receiver while
towing.

Storing the Tools
To store the tools:1. Return the tools (wheel wrench, jack handle, and jack handle extensions) to
the tool bag. Use the velcro straps to
secure the tool bag under the load floor
in the cargo area.
2. Position the jack and wheel blocks in the driver side trim panel over the
wheelhouse.
3. Turn the jack knob clockwise until the jack is secured tight in the mounting
bracket. Be sure to position the holes in
the base of the jack onto the pin in the
mounting bracket.
4. Close the trim panel door.
Storing a Flat Tire Inside of the Vehicle
If the vehicle has 275/60R20 or 275/50R22
size tires, the flat tire must be stored inside
of the vehicle in the cargo area using the
flat tire secure strap inside the glove box. 1. Store the tools. See “Storing the Tools”
earlier in this section.
2. If the vehicle has a short wheel base, the third row seat must be folded down to
provide sufficient space to store the flat
tire. If the third row seat cannot be folded down, the flat tire cannot be
stored and must be left in a safe
location, to be picked up at a later time.
3. Once there is sufficient space in the rear of the vehicle, lift the flat tire and place
it on top of the load floor, with the
valve stem pointed up.4. Remove the flat tire secure strap from
the glove box and place the loop end of
the strap through the cargo tie-down.
Place the hook end of the strap through
the loop and pull it until the strap is
fastened securely to the tie-down.
5. Route the hook end of the strap throughthe wheel, as shown.
6. Attach the hook to the other cargo tie-down in the rear of the vehicle.
7. Tighten the strap.
Full-Size Spare Tire
If this vehicle came with a full-size spare
tire, it was fully inflated when new,
however, it can lose air over time. Check the
inflation pressure regularly. See Tire Pressure
0 346 and
Vehicle Load Limits 0222 for information
regarding proper tire inflation and loading
the vehicle. For instructions on how to
remove, install, or store a spare tire, see Tire
Changing 0358.

Vehicle Care 383
Cargo Cover and Convenience Net
If equipped, wash with warm water and
mild detergent. Do not use chlorine bleach.
Rinse with cold water, and then dry
completely.
Care of Seat Belts
Keep belts clean and dry.
{Warning
Do not bleach or dye seat belt webbing.
It may severely weaken the webbing. In
a crash, they might not be able to
provide adequate protection. Clean and
rinse seat belt webbing only with mild
soap and lukewarm water. Allow the
webbing to dry.
Floor Mats
{Warning
If a floor mat is the wrong size or is not
properly installed, it can interfere with
the pedals. Interference with the pedals
can cause unintended acceleration and/or
increased stopping distance which can(Continued)
Warning (Continued)
cause a crash and injury. Make sure the
floor mat does not interfere with the
pedals.
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
pedals. 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.
Removing and Replacing the Floor Mats
Pull up on the rear of the driver side floor
mat to unlock each retainer and remove.
Reinstall by lining up the floor mat retainer
openings over the carpet retainers and
snapping into position.
Make sure the floor mat is properly secured
in place.
Verify the floor mat does not interfere with
the pedals.
