The security system helps to protect
your vehicle and valuables from
theft. The horn sounds and a
combination of headlights, position
lights, side marker lights and
taillights flashes if someone attempts
to break into your vehicle or remove
the audio unit. This alarm continues
for 2 minutes, then the system
resets. To reset an activated system
before the 2 minutes have elapsed,
unlock the driver's door with the key
or the remote transmitter/keyless
access remote.
The security system automatically
sets 15 seconds after you lock the
doors, hood, and the tailgate. For the
system to activate, you must lock the
doors and the tailgate from the
outside with the key, driver's lock
tab, door lock master switch, or
remote transmitter/keyless access
remote. The security system
indicator on the instrument panel
starts blinking immediately to show
you the system is setting itself.
Once the security system is set,
opening any door, the tailgate, or the
hood without using the key or the
remote transmitter/keyless access
remote, will cause it to alarm. It also
alarms if the audio unit is removed
from the dashboard or the wiring is
cut.The security system will not set if the
hood, tailgate, or any door is not fully
closed. If the system will not set,
check that the doors, the tailgate and
the hood are fully closed.
Do not attempt to alter this system or
add other devices to it.

Your vehicle's starting system has an
auto control mode. When you have
your keyless access remote and push
the engine start/stop button while
depressing the brake pedal, this
feature keeps the engine's starter
motor running until the engine
starts.
Follow these instructions to start the
engine:1. Apply the parking brake.
2. In cold weather, turn off all electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal.
In either of the following cases, you
should insert the keyless access
remote into the keyless remote slot.
For more information, see pages 202
and 203.●The keyless access remote system
main switch is off.
●The keyless access remote battery
becomes weak or dead.
4. Without touching the accelerator pedal, push and release the engine
start/stop button. You do not need
to hold the engine start/stop
button to start the engine. The
starter motor can run for up to 9
seconds to guarantee starting
when the outside temperature is
very low.
If you hold the engine start/stop
button for more than 7 seconds,
the starter motor, depending on
the outside temperature, runs for
up to 25 seconds until the engine
starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly
coded keyless access remote (or other
device) is used, the engine's fuel system
is disabled. For more information, see
page 149.The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem.
