Immobilizer
SeeRadio Frequency Statement 0290.
Immobilizer Operation
This vehicle has a passive theft-deterrent
system.
The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the transmitter leaves the vehicle.
The immobilization system is disarmed
when ENGINE START/STOP is pressed and a
valid transmitter is found in the vehicle.
The security light in the instrument cluster
comes on when there is a problem with
arming or disarming the theft-deterrent
system.
The system has one or more transmitters
matched to an immobilizer control unit in
your vehicle. Only a correctly matched transmitter will start the vehicle. If the
transmitter is ever damaged, you may not
be able to start your vehicle.
When trying to start the vehicle, the
security light comes on briefly when the
ignition is turned on.
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the vehicle off and try again.
If the vehicle will not change ignition modes
(ACC/ACCESSORY, on, off), and the RKE
transmitter appears to be undamaged, try
another transmitter. Or, you may try placing
the transmitter in the front cupholder. See
“Starting the Vehicle with a Low Transmitter
Battery”
underRemote Keyless Entry (RKE)
System Operation 07.
If the engine does not start with the other
transmitter or when the transmitter is in the
pocket in the front cupholder, the vehicle
needs service. See your dealer who can
service the theft-deterrent system and have
a new transmitter programmed to the
vehicle.
Do not leave the transmitter or device that
disarms or deactivates the theft-deterrent
system in the vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things, like
other vehicles, look farther away than
they really are. If you cut too sharply
into the right lane, you could hit a
vehicle on the right. Check the inside
mirror or glance over your shoulder
before changing lanes.
The passenger side mirror is convex shaped.
A convex mirror's surface is curved so more
can be seen from the driver seat.

Lighting Features
Entry Lighting
Some exterior lamps and interior lamps turn
on briefly at night, or in areas with limited
lighting, when
Kis pressed on the Remote
Keyless Entry (RKE) transmitter. When a
door is opened, the interior lamps come on.
They stay on for about 20 seconds. When all of the doors have been closed or the
ignition is turned on, they gradually
fade out.
This feature can be changed. See
“Vehicle
Locator Lights” underVehicle Personalization
(8 Inch Screen) 089 or
Vehicle Personalization (7 Inch Screen) 094.
Exit Lighting
Some exterior lamps and interior lights
come on at night, or in areas with limited
lighting, when the driver door is opened
after the ignition is turned off. The interior
lamps come on after the ignition is turned
off. The exterior lamps and interior lamps
remain on for a set amount of time, then
automatically turn off.
The exterior lamps turn off immediately by
turning the exterior lamp control off.
This feature can be changed. See Vehicle
Personalization (8 Inch Screen) 089 or
Vehicle Personalization (7 Inch Screen) 094.
Battery Load Management
The vehicle has Electric Power Management
(EPM) that estimates the battery's
temperature and state of charge. It then
adjusts the voltage for best performance
and extended life of the battery.
When the battery's state of charge is low,
the voltage is raised slightly to quickly bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. If the
vehicle has a voltmeter gauge or a voltage
display on the Driver Information Center
(DIC), you may see the voltage move up or
down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the power
needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, fog lamps, rear window
defogger, climate control fan at high speed,

emergency: 1. Brake using a firm steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location. 3. Come to a complete stop, shift to
P (Park), and turn the ignition off.
4. Set the parking brake. See Parking Brake
0 184.
