Total Weight on Your Vehicle’s
Tires
Be sure your vehicle’s tires are
inated to the upper limit for cold
tires. You will nd these numbers on
the Tire-Loading Information label.
SeeLoading the Vehicle on
page 8-28. Then be sure you do not
go over the GVW limit for your
vehicle, including the weight of the
trailer tongue.
Hitches
It is important to have the correct
hitch equipment. Crosswinds,
large trucks going by and rough
roads are a few reasons why
you will need the right hitch. Here
are some rules to follow:
The rear bumper on your 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 you have to make any holes
in the body of your vehicle when
you install a trailer hitch? If you
do, then be sure to seal the holes
later when you remove the hitch.
If you do not seal them, deadly
carbon monoxide (CO) from your
exhaust can get into your vehicle.
SeeEngine Exhaust on
page 8-12. Dirt and water can
also enter the vehicle.
Safety Chains
You should always attach chains
between your vehicle and your
trailer. Cross the safety chains under
the tongue of the trailer so that the
tongue will not drop to the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailer
manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains and do not
attach them to the bumper. Alwaysleave just enough slack so you can
turn with your rig. And, never allow
safety chains to drag on the ground.
Trailer Brakes
Does your trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer
brakes so you will be able to install,
adjust and maintain them properly.
Because you have anti-lock brakes,
do not tap into your vehicle’s brake
system. If you do, both brake
systems will not work well, or at all.
Trailer Wiring Harness
All of the electrical circuits required
for your trailer lighting system
can be accessed at the driver’s side
rear lamp connector. This connector
is located under the carpet on
the rear corner of the trunk
compartment.

(e)Make sure the safety belt
reminder light and safety belt
assemblies are working properly.
Look for any other loose or
damaged safety belt system parts. If
you see anything that might keep
a safety belt system from doing
its job, have it repaired. Have any
torn or frayed safety belts replaced.
Also see Airbag System Check
on page 1-31.
(f)Lubricate all key lock cylinders,
door hinges and latches, hood
hinges and latches and trunk lid
hinges and latches. More frequent
lubrication may be required
when exposed to a corrosive
environment. Applying silicone
grease on weatherstrips with a clean
cloth will make them last longer,
seal better, and not stick or squeak.
(g)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.(h)Change automatic transmission
fluid and filter if the vehicle is
mainly driven under one or more of
these conditions:
In heavy city traffic where the
outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 9-13 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.(j)A fluid loss in any vehicle system
could indicate a problem. Have
the system inspected and repaired
and the fluid level checked. Add
fluid if needed.
(k)If you drive regularly under dusty
conditions, inspect the filter at
each engine oil change.
(l)If you drive regularly under dusty
conditions, the filter may require
replacement more often.
(m)Drain, flush, and refill brake
hydraulic system at a regular service
interval (IorII) every two years.
This service can be complex;
you should have your dealer/retailer
perform this service. See Brakes
on page 9-24.
