Remote Hatch Release
Press the switch under the
main lamp control below
the instrument panel to
unlock the hatch
from
inside your vehicle.
The switch only works when the ignition switch
is in
RUN, ACC or when RAP is present. (See "Retained
Accessory Power" in the Index.)
NOTICE:
If you put things in the hatchback area, be sure
they won't break the glass when you close it.
Never slam the hatch down. You could break the
glass or damage the defogger grid (if equipped).
If you have an automatic transmission, your shift lever
must be in PARK (P) or NEUTRAL (N) to use the
switch. If you have a manual transmission and the
ignition is in RUN, you must set the parking brake
before you can use the switch.
On vehicles with the Content Theft-Deterrent System,
the hatch switch will not work while the system is
armed. See Tontent Theft-Deterrent System" in
