Driving With A Trailer - GMC 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 3-21 or Dual Automatic Climate
Control System on page 3-23.
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.
