Driving and Operating 199
The vehicle may have an electric steering
column lock. The lock is activated when the
ignition is turned off and either front 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.
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. Hold the brake pedal down and shift to P (Park). The
vehicle must be in P (Park) to turn the
ignition off.
4. Continue to hold the brake pedal down. 5. Set the parking brake. See
Electric
Parking Brake 0212.
6. Press ENGINE START/STOP once to turn the ignition off.
7. Release the brake pedal.

must be shut off while driving, press and
hold ENGINE START/STOP for longer than
two seconds, or press twice in five seconds.

to be used when the engine is off.
With the ignition off, pressing the button
one time without the brake pedal applied
will place the ignition system in
accessory mode.
The ignition will switch from accessory
mode to off after five minutes to prevent
battery rundown.

mode is for driving and starting. With the
ignition off, and the brake pedal applied,
pressing the button once will turn the
ignition on. Once engine cranking begins,
release the button. Engine cranking will
continue until the engine starts. See Starting
the Engine 0199. Service Mode
This power mode is available for service and
diagnostics, and to verify the proper
operation of the malfunction indicator lamp
as may be required for emission inspection
purposes. With the vehicle off, and the
brake pedal not applied, pressing and
holding the button for more than
five seconds will place the vehicle in Service
Mode. The instruments and audio systems
will operate as they do when the ignition is
on, but the vehicle will not be able to be
driven. The engine will not start in Service
Mode. Press the button again to turn the
ignition off.

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. SeeDefensive Driving
0 185. 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.
