9-16 Driving and Operating
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition to LOCK/OFF.
4. Set the parking brake. See Parking Brake on page 9‑34.{WARNING
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to ACC/

then the vehicle needs service.
B (ACC/ACCESSORY): This
position unlocks the steering wheel.
Some accessories can be used in
this position. C (ON/RUN):
The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, as well as to display
some warning and indicator lights.
This position can also be used for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes.
The battery could be drained if the
key is left in the ON/RUN position
with the engine off. The vehicle
might not start if the battery is
allowed to drain for an extended
period of time.

Center (DIC). See Transmission Messages on page 5‑34
for more
information. When the vehicle is
shifted into P (Park), the ignition
system will switch to OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
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, shift to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with

ignition will then remain in ON/RUN.
Service Only 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 Only Mode.
The instruments and audio systems
will operate as they do in ON/RUN,
but the vehicle will not be able to be
driven. The engine will not start in
Service Only Mode. Push the button
again to turn the vehicle off.
Starting the Engine
Place the transmission in the
proper gear.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
vehicle when it is already moving,
use N (Neutral) only.
Notice:
Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped. Notice:
The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the engine operates.
Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.
Manual Transmission
The shift lever should be in
N (Neutral) and the parking brake
engaged. Hold the clutch pedal
down to the floor and start the
engine. The vehicle will not start if
the clutch pedal is not all the
way down.
Starting Procedure (Key Access)
1. With your foot off the accelerator
pedal, turn the ignition key to
START. When the engine starts,
let go of the ignition.

Black plate (20,1)Buick Regal Owner Manual - 2012
9-20 Driving and Operating
The idle speed will go down as
your engine gets warm. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for
a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START for many seconds,
cranking will be stopped after
15 seconds to prevent cranking
motor damage. To prevent gear
damage, this system also
prevents cranking if the engine
is already running. Engine
cranking can be stopped byturning the ignition switch to
ACC/ACCESSORY or
LOCK/OFF.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor and holding it there
as you hold the key in START,
or press the START button, for
up to a maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, let go of
the key or button, and the
accelerator. If the vehicle starts briefly but then stops again, do
the same thing. This clears the
extra gasoline from the engine.
Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Starting Procedure (Keyless
Access)
1. If the vehicle has the keyless access system, the transmitter
must be in the vehicle. Put your
foot on the brake pedal and
push the START/STOP button.
When the engine begins
cranking, let go of the button.
The idle speed will go down as
your engine gets warm. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts.

9-22 Driving and Operating
eAssist Automatic Engine
Start/Stop
{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 has the automatic engine
start/stop 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 to LOCK/OFF, before
exiting the vehicle.
Vehicles with eAssist have an
automatic engine start/stop feature.
After the engine is started and has
reached operating temperature, the
auto stop feature may cause the
engine to turn off when the brakes are applied and the vehicle comes
to a complete stop. The vehicle
may remain in auto stop for up to
two minutes. When the brake is
released or the accelerator pedal is
applied, the engine will start. The
engine will continue to run until the
next auto stop.
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. See
Tachometer on
page 5‑11 for more information.
When the vehicle is turned off, the
tachometer will move to OFF. If the
driver door is opened while in auto
stop mode, a chime will sound.
To restart the engine during auto
stop, release the brake pedal or
press the accelerator pedal. The
engine starts immediately. The
vehicle continues to run until the
next stop.
There are several conditions which
may prevent an auto stop or cause
an auto start. The Engine Will Remain
Running When:
.The engine, transmission,
or high voltage battery is not
warmed up yet.
.The outside temperature is less
than
−20°C (−4°F).
.The air conditioning or defrost
system need the compressor to
maintain vehicle comfort. See
Dual Automatic Climate Control
System on page 8‑3 for more
information.
.The shift lever is in P (Park),
N (Neutral), R (Reverse),
or M (Manual Mode).
.The high voltage battery pack
charge is low.
.The 12‐volt vehicle battery
charge is low, or loads are high.
.The hood is not fully closed.
.Brake pedal pressure is high.
.If the MIL is on, auto stop may
be prevented.

Black plate (23,1)Buick Regal Owner Manual - 2012
Driving and Operating 9-23
The Engine Will Restart When:
.The brake pedal is released.
.The accelerator pedal is applied.
.Shifting out of D (Drive) to any
other gear.
.If eco air conditioning is
selected, the duration of the auto
stop will depend on the outside
temperature. This economy
mode improves fuel economy by
limiting the effects of the air
conditioning. The warmer it is
outside, the shorter the time
before the engine is restarted to
provide cabin cooling.
.The climate control system is
turned from off to normal air
conditioning or defrost. SeeDual
Automatic Climate Control
System on page 8‑3 for more
information.
.The engine is required to run for
either heater or climate control
performance. See Dual
Automatic Climate Control
System on page 8‑3 for more
information.
.The high voltage battery pack
charge is low and requires
recharging.
.Auto stop time is greater than
two minutes.
.The hood is opened.
Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below −18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).

Shifting Into Park
(Automatic Transmission)
{WARNING
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow.
Use this procedure to shift into
P (Park):
1. Hold the brake pedal down and set the parking brake.
See Parking Brake on page 9‑34
for more information.
2. Hold the button on the shift lever and push the lever toward the
front of the vehicle into P (Park). 3. Turn the ignition to LOCK/OFF.
4. Remove the key.
Leaving the Vehicle with the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
vehicle with the engine running, it
could overheat and even catch
fire. You or others could be
injured. Do not leave the vehicle
with the engine running.
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking
brake set.
Release the button and check that
the shift lever cannot be moved out
of 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; 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).

Black plate (26,1)Buick Regal Owner Manual - 2012
9-26 Driving and Operating
Shifting out of Park
(Automatic Transmission)
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is
designed to:
.Prevent ignition key removal
unless the shift lever is in
P (Park) with the shift lever
button fully released.
.Prevent movement of the shift
lever out of P (Park) unless the
ignition is in ON/RUN 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

It is better not to park with the
engine running. But if you ever have
to, here are some things to know.
{WARNING
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains carbon monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, seeEngine
Exhaust on page 9‑27.
{WARNING
It can be dangerous to get out of
the vehicle if the automatic
transmission shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll. Do
not leave the vehicle when the
engine is running unless you
have to. If you have left the
engine running, the vehicle can
move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
it is on fairly level ground, always
set the parking brake and move
the automatic transmission shift
lever to P (Park), or the manual
transmission shift lever to Neutral.
Follow the proper steps to be sure
the vehicle will not move. If the
vehicle has an automatic
transmission, see Shifting Into Park
