Liftgate
{ 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.
• 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.
If your vehicle has a power liftgate, see Power Liftgate
on page 2-14.
To unlock the liftgate, use the power door lock switch or
press the door unlock button on the Remote Keyless
Entry (RKE) transmitter twice. See Remote Keyless
Entry (RKE) System Operation on page 2-5.
To open the liftgate, press the touchpad on the
underside of the liftgate handle. The vehicle must be in
PARK (P) to open the liftgate. To close the liftgate,
use the pull cup or pull strap as an aid.
The liftgate has an electric latch. If the battery is
disconnected or has low voltage, the liftgate will not
open. The liftgate will resume operation when the battery
is reconnected and charged.
If the battery is properly connected and has adequate
voltage, and the liftgate still will not function, your vehicle
should be taken to a dealership for service.
