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 Systems in the
Index.
If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
See Engine Exhaust on
page 9 28.
If you open the liftgate
without checking for overhead
obstructions such as a garage
door, you could damage the
liftgate or the liftgate glass.
Always check to make sure the
area above and behind the liftgate
is clear before opening it.
A. License Plate Applique
B. Liftgate Handle
The liftglass or liftgate cannot be
opened if the rear wiper is in motion.
Attempting to open the liftglass or
liftgate while the rear wiper is in
motion will cause the release of the
liftglass or liftgate to delay until the
wipers are parked off the liftglass.
Manual Liftgate Operation
To unlock the liftgate, press
the power door lock switch or press
on the Remote Keyless Entry
(RKE) transmitter twice. See
Remote Keyless Entry (RKE)
System Operation on page 2 3.
Press the touch pad on the
underside of the liftgate handle (B)
and lift up.
Use the pull cup to lower and close
the liftgate. Do not press the touch
pad while closing the liftgate. This
will cause the liftgate to be
unlatched.
Power Liftgate Operation
On vehicles with a power liftgate,
the switch is on the overhead
console.
The vehicle must be in P (Park) to
use the power feature. The taillamps
will flash and a chime will sound
when the power liftgate moves.
