The Vehicle Security system is designed to
protect your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the Vehicle Security
system will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the Vehicle Security system.
If the Vehicle Security system is armed and the
battery becomes disconnected, the Vehicle
Security system will remain armed when the
battery is reconnected; the exterior lights will
flash, and the horn will sound. If this occurs,
disarm the Vehicle Security system.
REARMING OF THE SYSTEM

If something triggers the alarm, and no action is
taken to disarm it, the Vehicle Security system
will turn the horn off after 29 seconds,
five seconds between cycles, and up to eight
cycles if the trigger remains active. The Vehicle
Security system will then rearm itself.

SECURITY SYSTEM MANUAL OVERRIDE

The vehicle was parked for an extended
period of time (weeks, months).
The battery was recently replaced and was
not charged completely.
The battery was discharged by an electrical
load left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appli -
ances like vacuum cleaners, game consoles
and similar devices. What to do when an electrical load reduction
action message is present (“Battery Saver On”
or “Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if
possible:

Turn off redundant lights (interior or exterior).

Check what may be plugged in to power
outlets +12 Volts, 115 Volt AC, USB ports.

Check HVAC settings (blower, temperature).

Check the audio settings (volume).
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and
review specifications if any (load and Ignition
Off Draw currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).

The vehicle should have service performed if the
message is still present during consecutive trips
and the evaluation of the vehicle and driving
pattern did not help to identify the cause.
