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.
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 by
turning 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

Black plate (20,1)Buick Regal Owner Manual - 2013 - crc - 11/5/12
9-20 Driving and Operating
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start afterfive 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.
If the transmitter is not in the
vehicle or something is
interfering with the transmitter,
the Driver Information Center
(DIC) will display a message.
See Remote Keyless Entry
(RKE) System Operation on
page 2‑3 andKey and Lock
Messages on page 5‑31. If the battery in the keyless
access transmitter needs
replacing, a DIC message
displays. The vehicle can still be
driven. See
“Starting the Vehicle
with a Low Transmitter Battery”
in Remote Keyless Entry (RKE)
System Operation on page 2‑3.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the START
button is pressed, 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 button is pressed
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.
