Driving Information
Distracted Driving
Distraction comes in many forms and
can take your focus from the task of
driving. Exercise good judgment and
do not let other activities divert your
attention away from the road. Many
local governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep your
eyes on the road, keep your hands on
the steering wheel, and focus your
attention on driving.
. Do not use a phone in demanding
driving situations. Use a
hands-free method to place or
receive necessary phone calls.
. Watch the road. Do not read, take
notes, or look up information on
phones or other electronic devices.
. Designate a front seat passenger
to handle potential distractions.

220 DRIVING AND OPERATING
the vehicle is ready to be driven. This
could take up to 15 seconds at
extremely cold temperatures. See
Vehicle Ready Light (PLUG-IN Only)
0151.
PLUG-IN Operation
This vehicle combines gasoline and
electric propulsion. The gasoline
engine will automatically start to
provide power and then shut off to
save fuel.
The engine may remain
running when:
.
Accelerating aggressively or
climbing hills.
. Vehicle speed is greater than
125 km/h (75 mph).
. Charging the high voltage battery.
. The heater is being used.
The engine and transmission work
together to provide propulsion power
at the highest efficiency. This may
result in higher engine speeds.
Stop/Start System
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause the
vehicle to move. You or others may
be injured. Because the vehicle may
have an auto engine stop/start
feature, the vehicle's engine might
seem to be shut off; however, once
the brake pedal is released, the
engine will start up again.
Shift to P (Park) and turn the
ignition off before exiting the
vehicle.
The vehicle has a fuel saving stop/
start system to shut off the engine
and help conserve fuel.
Auto Engine Stop/Start
When the brakes are applied and the
vehicle is at a complete stop, the
engine may turn off. When stopped,
the tachometer may display Auto
Stop, or the Auto Stop light may come
on in the instrument cluster.
See Tachometer 0134 and Auto Stop Mode (Uplevel Cluster)
0150. When the
brake pedal is released or the
accelerator pedal is pressed, the
engine may restart.
Auto Stop may be deactivated if:
. A minimum vehicle speed is not
reached.
. The engine or transmission is not
at the required operating
temperature.
. The outside temperature is not in
the required operating range,
typically between -10 °C (14 °F)
and 50 °C (122 °F).
. The shift lever is in any gear other
than D (Drive).
. The battery has been recently
disconnected.
. The battery charge is low.
. The interior comfort level has not
reached the required level for the
climate control system or defog
settings.

DRIVING AND OPERATING 225
Warning (Continued)
on fairly level ground, always set
the parking brake and move the
shift lever to P (Park). SeeShifting
Into Park 0224. If you are towing a
trailer, see Driving Characteristics
and Towing Tips 0290.
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking brake
set. After shifting into P (Park), try to
move the shift lever out without first
pushing the button on the shift lever.
If you can, the shift lever was not
fully locked into P (Park).
Torque Lock
Torque lock is when the weight of the
vehicle puts too much force on the
parking pawl in the transmission. This
happens when parking on a hill and
shifting the transmission into P (Park)
is not done properly and then it is
difficult to shift out of P (Park). To
prevent torque lock, set the parking brake and then shift into P (Park). To
find out how, see "Shifting Into Park"
listed previously.
If torque lock does occur, the vehicle
may need to be pushed uphill by
another vehicle to relieve the parking
pawl pressure, so you can shift out of
P (Park).
Shifting out of Park
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to
prevent movement of the shift lever
out of P (Park), unless the ignition is
on and the brake pedal is applied.
The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See
Jump Starting - North
America 0374.
To shift out of P (Park): 1. Apply the brake pedal. 2. Release the parking brake. See
Electric Parking Brake 0235.
3. Press the shift lever button.
4. Move the shift lever.
If unable to shift out of P (Park): 1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift lever
button again.
3. Move the shift lever.
If the shift lever will not move from
P (Park), consult your dealer or a
professional towing service.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the vehicle
and ignite. Do not park over papers,
leaves, dry grass, or other things
that can burn.

276 DRIVING AND OPERATING
The vehicle has a Charging Status
Indicator (CSI) at the center of the
instrument panel near the windshield.
When the vehicle is plugged in and
the vehicle power is off, the CSI
indicates the following:
.Short Flashing Green –Vehicle is
plugged in. Battery is not fully
charged. Flash rate increases from
one to four flashes as battery
charges.
. Long Flashing Green –Vehicle is
plugged in. Battery is not fully
charged. Battery charging is
delayed.
. Solid Green –Vehicle is plugged
in. Battery is fully charged.
. Solid Yellow –Vehicle is plugged
in. It is normal for the CSI to turn
yellow for a few seconds after
plugging in a compatible charge
cord. The solid yellow may be
extended depending on the vehicle
and if there is a total utility
interruption via OnStar. See Utility
Interruption of Charging (PLUG-IN
Only) 0284. This may also indicate
that the charging system has
detected a fault and will not charge the battery. See
“Charge
Cord Status Indicators ”in Charge

If the vehicle is plugged in and vehicle
power is on, the CSI will flash or will
be solid green, depending on the
charge level. This also happens during
a remote start if the vehicle is
plugged in.
If the vehicle is plugged in and the
CSI is off, a total utility interruption
using OnStar or a charging fault has
been detected. See Utility Interruption
of Charging (PLUG-IN Only) 0284 or
“Charge Cord Status Indicators ”in
Charge Cord (PLUG-IN Only) 0279.
