WARNING
When towing a trailer, exhaust
gases may collect at the rear
of the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.

WARNING (Continued)
To maximize safety when towing
a trailer:
Have the exhaust system
inspected for leaks and make
necessary repairs before
starting a trip.
Never drive with the liftgate,
trunk/hatch, or rear-most
window open.
Fully open the air outlets
on or under the instrument
panel.
Adjust the Climate Control
system to a setting that
brings in only outside air
and set the fan speed to the
highest setting. See Climate
Control System in the Index.
For more information about
Carbon Monoxide, see Engine
Exhaust on page 9 36.
I n f o r ma t i o n P r o v i d e d b y :
Towing a trailer requires a certain
amount of experience. Get to know
the rig before setting out for the
open road. Get acquainted with the
feel of handling and braking with
the added weight of the trailer. And
always keep in mind that the vehicle
you are driving is now longer and
not as responsive as the vehicle is
by itself.
Before starting, check all trailer
hitch parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirror adjustments. If the
trailer has electric brakes, start the
vehicle and trailer moving and then
apply the trailer brake controller
by hand to be sure the brakes are
working. This checks the electrical
connection at the same time.
During the trip, check occasionally
to be sure that the load is secure,
and that the lamps and any trailer
brakes are still working.
