INSTALLATION OF MOBILE TWO-WAY RADIO SYSTEM
If a mobile two-way radio system is installed improperly or if a high-powered type is used, the EGI system
and other systems may be affected.
When the vehicle is to be equipped with a mobile two-way radio, observe the following precautions:
1. Install the antenna at the farthest point from control units.
2. Install the antenna feeder as far as possible from the control unit harnesses (at least 30 cm [11.8 in]).
3. Ensure that the antenna and feeder are properly adjusted.
4. Do not install a high-powered mobile two-way radio system.

REMOVAL OF IGNITION KEY ON AUTOMATIC
TRANSAXLE MODEL
The selector lever must be in P (PARK) to turn the ignition key
to the OFF position. If the switch seems to be off but the key
cannot be removed, the switch may still be in the ACC posi-
tion, or the selector lever may not be in P (PARK). Shift the
selector lever to P (PARK), and turn the ignition key to the
LOCK position. The key should now be free for removal.
