Manual Liftgate Operation
{WARNING
Exhaust gases can enter the
vehicle if it is driven with the
liftgate, trunk/hatch open, or
with any objects that pass
through the seal between the
body and the trunk/hatch or
liftgate. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled.
It can cause unconsciousness
and even death.
If the vehicle must be driven with
the liftgate, or trunk/hatch open:
.Close all of the windows.
.Fully open the air outlets
on or under the instrument
panel.(Continued)
WARNING (Continued)
.Adjust the Climate Control
system to a setting that
brings in only outside air
and set the fan speed to the
highest setting. See Climate
Control System in the Index.
.If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
To unlock the liftgate, use the
power door lock switch or press
the door unlock button on the
RKE transmitter twice. See Remote
Keyless Entry (RKE) System
Operation on page 2‑3. To open the liftgate, press the
touchpad under the liftgate handle.
The vehicle must be in P (Park)
to open the liftgate. To close the
liftgate, use the pull cup or pull
strap as an aid.
The liftgate will not open if the
battery is disconnected or has low
voltage. 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, the
vehicle should be taken to a dealer
for service.
