²Weigh your vehicle as you
customarily operate the vehicle
without cargo.
²Subtract the total weight of
passengers, driver and
aftermarket equipment and the
obtained weight (in the step
above) from the GCWR to
determine the trailer weight
your vehicloe can tow.
Trailer weight range
The trailer weight range is the
specified range by weight that the
trailer must fall within. The range
is between zero and the maximum
trailer weight rating found in this
chapter.
Using trailer brakes
Use electric brakes or manual,
automatic or surge type hydraulic
brakes that meet Federal and local
regulations. Install and adjust
brakes according to the
manufacturer's instructions.
Do not connect a trailer's
hydraulic brake system
directly to your vehicle's brake
system. Your vehicle may not
have enough braking power and
your chances of having a
collision greatly increase.
Using safety chains
Always connect the trailer's safety
chains to the vehicle. To connect
the chains, cross the chains under
the trailer tongue and attach to the

should the vehicle weight ratings
per axle or combination truck and
trailer exceed the weight ratings
listed on the Safety Compliance
Certification label located on the
driver's side door.
When connecting a trailer hitch:
1. Turn off the air suspension
switch.
2. Connect the trailer.
3. Turn the air suspension back on.
Adjusting an equalizing
hitch so the rear bumper
of the vehicle is lower or higher
than it was unloaded will defeat
the function of the load
equalizing hitch and may cause
unpredictable handling.
Driving while towing a trailer
Speed control (if equipped) may
not work properly while towing on
long, steep grades.
Driving with an automatic
transmission:
²use D, 1 or 2 rather than
Dwhile towing up or down
steep hills
²anticipate stops and brake
gradually.
Towing behind another vehicle
Your vehicle can not be flat towed
with all wheels on the ground.
No neutral tow kit is available for
your vehicle.

²Turn off the ignition.
²Set the parking brake.
²Activate the hazard flashers.

Removing flat tire and installing
spare
6. Use the tip of the lug wrench to
remove any wheel trim. Insert the
tapered end of the lug wrench
behind the wheel covers or
hubcaps and twist off.
7. Loosen the wheel nuts with the
lug wrench. Do not remove the lug
nuts until the tire has been raised
off the ground.
8. Insert the jack handle into the
jack and use the handle to slide
the jack under the vehicle.
9. Position the jack according to
the following guides and turn the
jack handle clockwise until the
wheel is completely off the ground.
²When one of the back wheels is
off the ground, the transmission
alone will not prevent the
vehicle from moving or slipping
off the jack, even if the vehicle
is in P (Park). To prevent the
vehicle from moving when you
change the tire, be sure that the
parking brake is set and the
diagonally opposite wheel is
blocked. If the vehicle slips off
the jack, someone could be
seriously injured.
