Locking Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow, mud,
ice, sand, or gravel. When traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. The limited-slip rear axle
also gives the driver enhanced control
when cornering hard or completing a
maneuver, such as a lane change. For
vehicles with limited-slip rear axle, the
rear axle fluid should be changed. See
Maintenance Schedule
0359.

[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD. The gap setting will
be maintained until it is changed. Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See

wheel light bar is flashing red.
If the steering wheel light bar
flashes red, immediately resume
manual steering to prevent serious
injury or death. If you do not
resume manual steering, the vehicle
will begin to slow in the same lane
and eventually come to a complete
stop on the freeway. Any time the steering wheel light bar
flashes red, resume manual steering
immediately. The instrument cluster
light

.A Super Cruise system fault
occurs.
Attention to the Road
{Warning
Super Cruise is a driver assistance
system and cannot accurately
detect or predict all situations.
Super Cruise is not a crash
avoidance system. To prevent
serious injury or death, 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 0173. Super Cruise also
cannot determine whether you are
awake, asleep, impaired, or properly
focused on safe driving. The vehicle
could crash into other vehicles,
drive out of the lane, or drive off
the road. Complete attention is
always required while driving, even
while using Super Cruise. Be
prepared to take over steering or
apply the brakes at any time.
{Warning
To prevent serious injury or death,
be alert and pay special attention
when passing highway exits,
entrances, and crossings with Super
Cruise, and be ready to take control
of the vehicle when necessary.
Changes in lane markings around
exits and entrances can
momentarily cause Super Cruise to
not detect the correct lane. If this
occurs, Super Cruise may attempt
steering inputs to bring the vehicle
back into the correct lane and, in
rare circumstances, could
over-correct and cause the vehicle
to momentarily cross into a lane
next to your vehicle unless you
manually steer to maintain your
lane position. The Driver Attention System (DAS) on
the steering column continually
monitors driver head and eye position
to estimate driver attention to the
road. The camera does not record or
share pictures, audio, or video.
Sunglasses, hats, or other types of
clothing that change the shape of the
head may interfere with camera
performance. To improve camera
performance, raise or lower the
steering wheel, or change the seat
position.
