Lighting Features
Entry Lighting
The headlamps, taillamps, license
plate lamps, reverse lamps, dome
lamps, and most of the interior lights
turn on briefly, when the Remote
Keyless Entry (RKE)
Kis pressed,
or when the door handle is pulled on
a Keyless Access Vehicle. See
Ignition Positions (Key Access)
on
page 8‑18or Ignition Positions
(Keyless Access)on page 8‑19.
After about 30 seconds the exterior
lamps turn off, and then the dome
and remaining interior lights will dim
to off. Entry lighting can be disabled
manually by changing the ignition
out of the OFF position, or by
pressing the Remote Keyless
Entry (RKE)
Qbutton. This feature can be activated or
deactivated in the menu SETTINGS
in the Info Display. Press CONFIG
on the infotainment system to call
up the menu. See
Vehicle
Personalization on page 4‑38.
Exit Lighting
The headlamps, taillamps, parking
lamps, reverse lamps, and license
plate lamps come on at night, or in
areas with limited lighting, when the
key is removed from the ignition.
The dome lamps also come on
when the key is removed from the
ignition. The exterior lights and
dome lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
For a vehicle with Keyless Access,
the exterior lights and dome lamps
automatically turn on when a door is
opened after the ignition is turned
off. See Ignition Positions (Key
Access)
on page 8‑18or Ignition
Positions (Keyless Access)on
page 8‑19. The exterior lights turn off
immediately by turning the exterior
lamps control to OFF.
The exit lighting feature can be
activated, deactivated, or the
timeframe for the lighting can be
changed in the menu Settings in the
Info. Display. Press CONFIG on the
Infotainment system to access the
menu. See
Vehicle Personalization
on page 4‑38.
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

Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with push-button
start.
Pressing the button cycles it through
three positions, ACC/ACCESSORY,
ON/RUN/START and OFF.
The transmitter must be in the
vehicle for the system to operate.
If the push-button start is not
working, the vehicle may be near a
strong radio antenna signal causing
interference to the keyless accesssystem. See
Remote Keyless Entry
(RKE) System Operation (Key
Access)
on page 1‑3or Remote
Keyless Entry (RKE) System
Operation (Keyless Access)
on
page 1‑5for more information.
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN and the brake pedal must
be applied.
OFF: When this button is pressed
with the engine running, the engine
will be turned off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP)
on page 8‑20for
more information.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See Driver Information Center (DIC)
on page 4‑25for more information. When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
ACC/ACCESSORY:
This position
allows you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied, will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
run down.
ON/RUN/START: This position is
for driving and starting. With the
ignition off, and the brake pedal
applied, pressing the button once
will place the ignition system in ON/
RUN/START. Once engine cranking
begins, release the button. Engine
cranking will continue until the
engine starts. See Starting the
Engine
on page 8‑20for more
information. The ignition will then
remain in ON/RUN.

8-22 Driving and Operating
If the battery in the keyless
access transmitter needs
replacing, the DIC displays
REPLACE BATTERY IN
REMOTE KEY. The vehicle can
still be driven. See Starting the
Vehicle with a Low Transmitter
Battery inRemote Keyless Entry
(RKE) System Operation (Key

The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the START
button is pressed, and then
released when the engine
begins cranking, the engine will
continue cranking for a few
seconds or until the vehicle
starts. If the engine does not
start and the button is pressed
for many seconds, cranking will
be stopped after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by pressing the START button a
second time.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
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
5-10 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 the key in START,
or press the START button, for
up to a maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the cranking motor to cool down.
When the engine starts, let go of
the key or button, and the
accelerator. If the vehicle starts
briefly but then stops again, do
the same thing. This clears the
extra gasoline from the engine.
Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below
−18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).
