Climate Control Function with Stop/
Start (If Equipped)
The climate control system depends
on other vehicle systems for heat and
power input. The climate control
system will balance stop/start
efficiency with air conditioning
comfort and defog operation. Certain
climate control settings can result in
fewer Auto Stops.
The following climate control settings
result in fewer Auto Stops:
.
Defrost mode
. High fan speed settings
. Extreme temperature settings
For maximum air conditioning
comfort, use the stop/start disable
switch. See “Auto Stop/Start ”under
Starting the Engine 0194.

needed to help quickly cool the inside
of the vehicle.
The climate control system may have
a sensor to detect air pollution. When
using automatic air recirculation, the
air quality control system may
operate. To adjust the sensitivity of
the air quality sensor, see “Climate
and Air Quality” underVehicle
Personalization 0144.@:Touch or press@on the
display or center stack to alternate
between recirculating air inside the
vehicle or pulling in outside air. The
indicator light is lit when recirculation
mode is active. This helps to quickly cool the air inside the vehicle or
reduce outside air and odors that
might enter.
Touching or pressing

automatic recirculation. Touch or
press AUTO on the display or center
stack to return to automatic
operation; recirculation runs
automatically as needed.
Manual recirculation mode is not
available when in Defrost or Defog
modes.
Auto Defog : The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to outside
air supply and turn on the air
conditioner. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. To turn Auto Defog off or
on, see “Climate and Air Quality”
under Vehicle Personalization 0144.

Sensor
The solar sensor, on top of the
instrument panel near the windshield,
monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed, recirculation,
and air delivery mode for best
comfort.
If the sensor is covered, the automatic
climate control system may not work
properly.Air Quality Sensor
If equipped with an air quality sensor,
the climate control system adjusts to
limit some exhaust fumes from being
pulled inside the vehicle.
Touch or press AUTO on the display
or center stack to activate the air
quality sensor. Recirculation is
automatically selected when poor
quality air is detected. The air quality
sensor will not maintain recirculation
for an extended period to prevent the
air inside the vehicle from becoming
too dry or stuffy.
Under certain conditions, the air
quality sensor will not activate, such
as during cold weather or with
extreme odors. Touch or press
@to
activate recirculation.
The air quality sensor system does not
protect against carbon monoxide (CO),
which you cannot see or smell. See
Engine Exhaust 0199. The air quality
sensor operation can be adjusted. See
“Climate and Air Quality” under
Vehicle Personalization 0144.

DRIVING AND OPERATING 193
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
Indicator Lights) :When the vehicle
is stopped, press ENGINE START/
STOP 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) 0197.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is switched
to OFF and the driver door is opened.
A sound may be heard as the lock
actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service.
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.
If the vehicle must be shut off in an
emergency:
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.
3. Come to a complete stop, shift to P (Park), and turn the ignition to
OFF. On vehicles with an
automatic transmission, the shift lever must be in P (Park) to turn
the ignition switch to the OFF
position.
4. Set the parking brake. See Electric Parking Brake 0204.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold the ENGINE START/
STOP button for longer than
two seconds, or press twice in
five seconds.
ACC/ACCESSORY (Amber Indicator
Light) : This mode allows you to use
some electrical accessories when the
engine is off.
