Driving With A Trailer - GMC 2004 Envoy Owner's Manual

Driving with a Trailer

CAUTION:
{
If you have a rear-most window open and
you pull a trailer with your vehicle, carbon
monoxide (CO) could come into your vehicle.
You can not see or smell CO. It can cause
unconsciousness or death. See Engine
Exhaust on page 2-34. To maximize your
safety when towing a trailer:
•
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
•
Keep the rear-most windows closed.
CAUTION: (Continued)
CAUTION: (Continued)
•
If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
the climate control setting for maximum
air because it only recirculates the air
inside your vehicle. See Dual Climate
Control System on page 3-22.
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself 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 a good deal longer and not nearly as
responsive as your vehicle is by itself.
