Courtesy Lamps/Illuminated Entry
The GEM/CTM illuminates the interior courtesy lamps when any door is ajar. The GEM also receives a signal from the Remote Anti-theft Personality
(RAP) module for keyless entry illumination. All interior courtesy lamps are turned off when any of the following occur:
^
Twenty-five seconds have elapsed since the illuminated entry feature was activated.
^
The ignition switch is turned to RUN.
^
Vehicle speed is over 25 km/h (15 mph) (a new ajar signal will turn on courtesy lamps only if the vehicle speed is less than 16 km/h (10 mph) -
GEM only).
Delayed Accessory (GEM only)
The delayed accessory feature provides power to the power windows for ten minutes after the ignition switch is moved from the RUN to the OFF
position. If during this ten-minute period either door is opened, the delayed accessory relay will be de-energized.
One-Touch Down Window (GEM only)
The power switch for the driver window control has two detents for the down window control. With the ignition switch in RUN or ACC, pressing the
first detent (normal mode) allows manual down window control; pressing the switch farther to the second detent (auto) will cause the driver window to
automatically move to the full down position. Pressing either the up or down window switch will cancel an auto mode operation in progress.
Transfer Case (4-Wheel Drive - GEM Only)
Two types of 4-wheel drive systems are offered: the Mechanical Shift-On-the-Fly (MSOF) and the Electronic Shift-On-the-Fly (ESOF).
