Midgate
{CAUTION:
It can be dangerous to drive with the cargo
area covered and the tailgate and the midgate
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the tailgate
and midgate open or if electrical wiring or
other cable connections must pass through
the seal between the body and the midgate:
Make sure all windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the
setting on outside air. That will force
outside air into your vehicle. SeeDual
Climate Control System on page 3-20.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-40.
Midgate
Your vehicle is equipped with a midgate and power
midgate glass. The midgate allows you to extend the
length of your vehicle’s cargo area.

your vehicle to extend into the cab. The midgate
cannot be lowered when the glass is up.
To lower the midgate, do the following:

unsecured safety belts can be damaged and
may not restrain you in a crash. To help avoid
personal injury, always secure belts in the
retainers before operating the midgate.
2-13
