Driving and Operating 231
Terrain Mode is only available on vehicles
equipped with the single speed
transfer case.
Terrain Mode can only be active when:
.Vehicle speed is less than 80 km/h
(50 mph).
.The transfer case is in 4m.
Frequent use of this mode may cause brake
wear due to the light braking.
The vehicle automatically exits the mode if
the brakes get too hot. Terrain Mode can be
turned back on after the brakes have cooled.
When Terrain Mode is selected:
.Auto Engine Start/Stop is disabled.
.The Terrain Mode indicator displays on
the instrument cluster.
Magnetic Ride Control
This vehicle may have a semi-active damping
system called Magnetic Ride Control. With
this feature, improved vehicle ride and
handling is provided under a variety of
passenger and loading conditions.
Locking Rear Axle
Vehicles with a locking rear axle can give
more traction on snow, mud, ice, sand,
or gravel. It works like a standard axle most
of the time, but when traction is low, this
feature will allow the rear wheel with the
most traction to move the vehicle.
Four Corner Air Suspension
System
The Four Corner Air Suspension feature
provides full time load leveling capability
along with the benefit of adjusting ride
height for increased convenience and
capability.
{Warning
To help avoid personal injury or death,
make sure the area underneath the
vehicle and inside the wheel wells is clear
when lowering the vehicle.
{Warning
To help avoid personal injury or death,
always select the lowest ride height for
the current driving conditions. Higher ride
heights raise the vehicle's center of
gravity, increasing the chance of a
rollover during extreme maneuvers.
{Warning
Heavy loads on the roof rack will make
the vehicle's center of gravity higher,
increasing the possibility of a rollover. To
avoid losing control of the vehicle, always
select the normal height setting and
avoid high speeds, sudden starts, sharp
turns, sudden braking, or abrupt
maneuvers when carrying cargo on the
roof rack.

246 Driving and Operating
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. SeeRoof Rack System 092.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield behind
the rearview mirror, and the sensors on the
front of the vehicle can become blocked by
snow, ice, dirt, mud, or debris. This area
needs to be cleaned for ACC to operate
properly.
If ACC will not operate, regular cruise control
may be available. See “Switching Between
ACC and Regular Cruise Control” previously
in this section. Always consider driving
conditions before using either cruise control
system.
For cleaning instructions, see “Washing the
Vehicle” underExterior Care 0390.Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled roads
that are separated from opposing traffic.
Super Cruise can also steer to perform a
lane change under certain conditions on
Super Cruise-enabled roads.
A lane change can be initiated by the driver
using the turn signal lever.
The Super Cruise System may initiate a lane
change maneuver in following scenarios:
.to pass slower traffic
.when the current lane is ending ahead
.to return to the initial lane
See “Super Cruise Lane Change” later in this
section and Turn and Lane-Change Signals
0 139.
{Warning
Super Cruise can only assist to maintain
lane position, or steer to change lanes,
when driving on compatible roads. You
must supervise the driving task and
monitor the road conditions. You may

need to respond to traffic events by
steering, braking, or accelerating. See
Defensive Driving.
Super Cruise is:
.Not a self-driving system
.Not a crash avoidance or warning
system
.Not a substitute for proper supervision
of the driving task.
Super Cruise uses the following to detect
the current lane position and lane markings
ahead on compatible roads under certain
conditions:
.Cameras
.Global Positioning System (GPS) sensing
.A high-precision map
.GPS-enhancement data downloaded
through OnStar
Super Cruise works with Adaptive Cruise
Control (ACC), which controls acceleration
and braking while Super Cruise is enabled
and operating. Review and understand both
