Power Liftgate
Power Liftgate Operation
{ CAUTION:
It can be dangerous to drive with the liftgate
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 liftgate open, or if
electrical wiring or other cable connections
must pass through the seal between the body
and the liftgate:
• Make sure all other windows are shut.
• Turn the fan on your heating or cooling
system to its highest speed with the
recirculation mode off. That will force
outside air into your vehicle. See Climate
Control System in the index.
CAUTION: (Continued)
CAUTION: (Continued)
• If you have air outlets on or under the
instrument panel, open them all the way.
• If your vehicle has a power liftgate, disable
the power liftgate function.
See Power Liftgate on page 2-14.
Your vehicle may have a power liftgate. The vehicle
must be in PARK (P) to use the power feature.
The taillamps will flash and a chime will sound when the
power liftgate is used.
