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,

Driving and Operating 175
ON/RUN/START (Green Indicator Light) :This
mode is for driving and starting. With the
ignition off, and the brake pedal applied,
pressing ENGINE START/STOP once will place
the ignition system in ON/RUN/START.
Once engine cranking begins, release ENGINE
START/STOP. Engine cranking will continue
until the engine starts. See Starting the
Engine 0175.
The engine will then remain in ON/RUN.
Service Mode
This power mode is available for service and
diagnostics, and to verify the proper
operation of the malfunction indicator lamp
as may be required for emission inspection
purposes.
With the vehicle off, and the brake pedal
not applied, pressing and holding ENGINE
START/STOP for more than five seconds will
place the vehicle in Service Mode.
The instruments and audio system will
operate as they do in ON/RUN, but the
vehicle will not be able to be driven. The
engine will not start in Service Mode.
Press ENGINE START/STOP again to turn the
vehicle off.Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). To restart the vehicle when it is
already moving, use N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped.
Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
See Add-On Electrical Equipment 0200.
Starting Procedure 1. With the Keyless Access system, the RKE transmitter must be in the vehicle. Press
ENGINE START/STOP with the brake pedal
applied. When the engine begins
cranking, let go of the button.
The idle speed will go down as the
engine gets warm. Do not race the
engine immediately after starting it. If the RKE transmitter is not in the
vehicle, if there is interference, or if the
RKE transmitter battery is low, the Driver
Information Center (DIC) will display a
message. See
Driver Information Center
(DIC) 086 and
Remote Keyless Entry (RKE) System
Operation 07.
Caution
Cranking the engine for long periods of
time, by pressing ENGINE START/STOP
immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at
least 15 seconds between each try, to let
the cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor and holding it there as you
hold ENGINE START/STOP, for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.
