3. Immediately after completing Step 2, press and hold
/until
the turn signal lamps flash, or for

Vehicles with an automatic climate
control system will default to a
heating or cooling mode depending
on the outside temperature during a
remote start. When the key is turned
to ON/RUN (key access), or the
ON/RUN/START ignition position
is selected (keyless access), the
climate control system will turn on
at the setting the vehicle was set to
when the vehicle was last turned off.
Vehicles with heated or heated and
ventilated front seats can have this
feature turn on automatically during
a remote start. See

Heated Seats” and“Remote Start
Vented Seats” underVehicle
Personalization on page 5‑39
for more information. Extending Engine Run Time
For a 10-minute extension, repeat
Steps 1 and 2 while the engine is
still running. The remote start can
only be extended once.
When the remote start is extended,
the second 10 minutes will start
immediately.
For example, if the vehicle has
been running for five minutes, and
10 minutes are added, the engine
will run for a total of 15 minutes.
A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
The vehicle's ignition must be
turned on and then back off before
the remote start procedure can be
used again.

The headlamps, taillamps, license
plate lamps, back‐up lamps, dome
lamps, and most of the interior lights
turn on briefly, when the Remote
Keyless Entry (RKE)
Kbutton is
pressed, or when the door handle is
pulled on a keyless access vehicle.
See Ignition Positions (Key Access)
on page 9‑17 orIgnition Positions
(Keyless Access) on page 9‑19.
After about 30 seconds the exterior

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

time, then automatically turn off.
For a vehicle with keyless access,
the exterior lights and dome lamps

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.

Driving and Operating 9-19
Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with push‐button
start.
Pressing the button cycles it through
three modes, ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/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 neara strong radio antenna signal
causing interference to the keyless
access system. See
Remote
Keyless Entry (RKE) System
Operation on page 2‑4 for 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.
Stopping the Engine/OFF
(No LED Lights): When the
vehicle is stopped, press the
engine START/STOP button
once to turn the engine 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 9‑24 for
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
Transmission Messages on
page 5‑38 for more information.
When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
In an emergency, if the vehicle must
be shut off while driving:
1. Brake using a firm and 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.
