If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers on
page 5-105. If the fuse does not need to be replaced, you
may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
Theft-Deterrent system when leaving your vehicle.
