Set the parking brake bef ore you put
the transmission in Park. This keeps
the car from moving and putting
pressure on the parking mechanism
in the transmission making it
easier to move the shif t lever out of
Park when you want to drive away. Lockthedoorswiththekeyorthe
remote transmitter. Check the
indicator on the driver’s door to
verify that the security system is
set.
Never park over dry leaves, tall
grass, or other f lammable
materials. The three way catalytic
converter gets very hot, and could
cause these materials to catch on

Any hitch used on your vehicle must
be properly bolted to the underbody. Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, and
how much load you are towing.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and that it meets
f ederal, state, province, and local
regulations.
The best way to conf irm that vehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, check the tongue
load the f irst time you set up a
towing combination (a f ully-loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.
Always use saf ety chains. Make sure
they are secured to both the trailer
and hitch, and that they cross under
the tongue so they can catch the
trailer if it becomes unhitched.
Leave enough slack to allow the
trailer to turn corners easily, but do
not let the chains drag on the ground.
