CLIMATE CONTROLS 201
Sensor
The solar sensor, on top of the
instrument panel near the windshield,
monitors the solar intensity.
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 Vents
Adjustable air vents are in the center
and on the sides of the instrument
panel, and on the rear of the center
console storage.
Move the slider knobs to change the
direction of or to close off the airf low.
Operation Tips
.Clear away any ice, snow, or leaves
from air inlets at the base of the
windshield that could block the
flow of air into the vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.Keep the path under the front seats
clear of objects to help circulate the
air inside of the vehicle more
effectively.
.Use of non-GM approved hood
deflectors can adversely affect the
performance of the system. Check
with your dealer before adding
equipment to the outside of the
vehicle.
.Do not attach any devices to the air
vent slats. This restricts airf low and
may cause damage to the air vents.
Maintenance
Passenger Compartment
Air Filter
The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle. The
filter should be replaced as part of
routine scheduled maintenance. See
Maintenance Schedule0358.
See your dealer regarding replacement
of the filter.

DRIVING AND OPERATING 237
Driver Mode Control Switch
To activate each mode, press the
MODE button on the center console.
Tour Mode : Use for normal city and
highway driving to provide a smooth
ride. This setting provides balance
between comfort and handling. This is
the standard/default mode. There is
no persistent indicator in the
instrument cluster for this mode.
AWD Mode : AWD Mode provides
torque to all four wheels. Select AWD
to improve traction and control on
slippery road surfaces, such as gravel, sand, wet pavement, snow, and ice.
For more information on AWD Mode,
see
All-Wheel Drive 0232.
Sport Mode : Use where road
conditions or personal preference
demand a more controlled response.
Sport Mode improves vehicle handling
and acceleration on dry pavement.
When active, Sport Mode modifies
steering efforts, transmission shifting,
and AWD torque, if equipped.
The Performance Algorithm Liftfoot
(PAL) feature is enabled in Sport
Mode. PAL allows the transmission to
hold the current gear after a quick
release of a heavily applied accelerator
pedal. This provides greater engine
braking and enhanced vehicle control.
When PAL is activated, there may be
an additional gear symbol that
appears in the instrument cluster
display. See Performance Shifting Light
0 109.
Off-Road Mode : Use this mode for
off-road recreational driving. When
active, Off–Road Mode should be used
to improve driving at moderate
speeds, on grass, gravel, dirt, unpaved
roads, or snow-covered roads. The accelerator pedal is tuned for off-road
use. This mode modifies pedal
mapping, AWD, ESC, and TCS
Performance.
Snow/Ice Mode :
Snow/Ice Mode
improves vehicle acceleration on snow
and ice covered roads. When active,
Snow/Ice Mode will adjust
acceleration to optimize traction on
slippery surfaces. This can
compromise the acceleration on dry
asphalt. This feature is not intended
for use when the vehicle is stuck in
sand, mud, ice, snow, or gravel. If the
vehicle becomes stuck, see If the
Vehicle Is Stuck 0214.
Cruise Control
{
Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic. (Continued)
