For vehicles being dinghy towed, the vehicle should be
run at the beginning of each day and at each RV
fuel stop for about ve minutes. This will ensure proper
lubrication of transmission components. Re-install
the fuse to start the vehicle.
To tow your vehicle from the front with all four wheels
on the ground:
1. Position the vehicle to tow and then secure it to the
towing vehicle.
2. Shift the transmission to P (Park) and turn the
ignition to LOCK/OFF.
3. Set the parking brake.
4. Turn the ignition to ACC/ACCESSORY.
5. Shift the transmission to N (Neutral).
6. To prevent your battery from draining while the
vehicle is being towed, remove the 50 amp
BATT1 fuse from the underhood fuse block and
store in a safe location. SeeUnderhood Fuse Block
on page 5-115.
7. Release the parking brake.Notice:If you tow your vehicle without performing
each of the steps listed under “Dinghy Towing,”
you could damage the automatic transmission.
Be sure to follow all steps of the dinghy towing
procedure prior to and after towing your vehicle.
Notice:If you exceed 65 mph (105 km/h) while
towing your vehicle, it could be damaged. Never
exceed 65 mph (105 km/h) while towing your vehicle.
Once you have reached your destination:
1. Set the parking brake.
2. Reinstall the 50 amp BATT1 fuse to the underhood
fuse block.
3. Shift the transmission to P (Park), turn the ignition
to LOCK/OFF and remove the key from the ignition.
4. Release the parking brake.
Notice:Don’t 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.

You need new tires if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage that
cannot be repaired well because of the size or
location of the damage.
The rubber in tires degrades over time, even if they are
not being used. This is also true for the spare tire, if your
vehicle has one. Multiple conditions affect how fast this
aging takes place, including temperatures, loading
conditions, and in ation pressure maintenance. With
proper care and maintenance tires will typically wear out
before they degrade due to age. If you are unsure about
the need to replace your tires as they get older, consult
the tire manufacturer for more information.
Buying New Tires
GM has developed and matched speci c tires for
your vehicle. The original equipment tires installed
on your vehicle, when it was new, were designed
to meet General Motors Tire Performance Criteria
Speci cation (TPC Spec) system rating. If you need
replacement tires, GM strongly recommends that
you get tires with the same TPC Spec rating. This
way, your vehicle will continue to have tires that are
designed to give the same performance and vehicle
safety, during normal use, as the original tires.
GM’s exclusive TPC Spec system considers over
a dozen critical speci cations that impact the
overall performance of your vehicle, including
brake system performance, ride and handling,
traction control, and tire pressure monitoring
performance. GM’s TPC Spec number is molded
onto the tire’s sidewall near the tire size. If the
tires have an all-season tread design, the
TPC Spec number will be followed by an MS
for mud and snow. SeeTire Sidewall Labeling
on page 5-50for additional information.

4. To identify the appropriate jacking location, nd the
V–shaped locating notches in the molding.
Notice:If a jack is used to raise the vehicle
without positioning it correctly, your vehicle could
be damaged. When raising your vehicle on a jack,
avoid contact with the rear axle control arms.
5. Do not raise the vehicle yet. Put the compact spare
tire near you.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.
6. Attach the lug wrench to the jack, and turn
the wrench clockwise to raise the jack head
3 inches (7.6 cm).
