3. Immediately after completingStep 2, press and hold
/for at
least two seconds or until the
turn signal lamps flash. The turn
signal lamps flashing confirms
the request to remote start the
vehicle has been received.
When the engine starts, the parking
lamps will turn on and remain on as
long as the engine is running. The
doors will be locked and the climate
control system may come on.
The engine will continue to run for
10 minutes. Repeat the steps for a
10-minute time extension. Remote
start can be extended only once.
Start the vehicle before driving.
Extending Engine Run Time
For a 10-minute extension, repeat
Steps 1–3 while the engine is still
running. The remote start can be
extended once.
When the remote start is extended,
the second 10 minutes will start
immediately. For example, if the engine has been
running for five minutes, and
10 minutes are added, the engine
will run for a total of 15 minutes.
A maximum of two remote starts,
or a single start with an extension,
is allowed between ignition cycles.
The vehicle's ignition must be
turned on and then back off before
the remote start procedure can be
used again.
Canceling a Remote Start
To cancel a remote start, do one of
the following:
.Aim the RKE transmitter at the
vehicle and press and hold
/
until the parking lamps turn off.
.Turn on the hazard warning
flashers.
.Turn the vehicle on and then off.
Conditions in Which Remote Start
Will Not Work
The remote vehicle start feature will
not operate if:
.The key is in the ignition (key
access) or if the key is in the
vehicle (keyless access).
.The hood is not closed.
.The hazard warning flashers
are on.
.The malfunction indicator lamp
is on.
.The engine coolant temperature
is too high.
.The oil pressure is low.
.Two remote vehicle starts, or a
single remote start with an
extension, have already
been used.
.The vehicle is not in P (Park).

SeeFuel System Messages on
page 5‑31 for more information.
Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge moves a little while
turning a corner or speeding up.
.The gauge takes a few seconds
to stabilize after the ignition is
turned on, and will go back to
empty when the ignition is
turned off.
Driver Efficiency Gauge
For eAssist vehicles, this gauge
assists in driving efficiently and may
vary based on driver input.
To maximize efficiency, keep the
gauge pointed in the solid green
zone in the center of the gauge.
The gauge moves to the left when
braking and to the right when
accelerating. When either is done
aggressively, the vehicle is being
driven less efficiently and the gauge
will move further from the center.
Engine Coolant
Temperature Gauge

English
This gauge shows the engine
coolant temperature.
If the indicator needle moves to the
hot side of the gauge toward the
shaded area, the engine is too hot.
In eAssist vehicles, the engine
coolant warning light will come on
when the engine is too hot. See
Engine Coolant Temperature
Warning Light on page 5‑21 for
more information. If the vehicle has been operated
under normal driving conditions, pull
off the road, stop the vehicle, and
turn off the engine as soon as
possible.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their safety belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue severaltimes if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver safety belt is buckled,
neither the chime nor the light
comes on.
Passenger Safety Belt
Reminder Light
There is a passenger safety belt
reminder light near the passenger
airbag status indicator. See
Passenger Sensing System on
page 3‑23.
When the vehicle is started, this
light flashes and a chime may come
on to remind passengers to fasten
their safety belt. Then the light stays
on solid until the belt is buckled.
This cycle continues several times if

Black plate (21,1)Buick Regal Owner Manual - 2013 - crc - 11/5/12
Instruments and Controls 5-21
If the light does not come on, have
the vehicle serviced by the dealer.
If the system is working normally,
the indicator light turns off.
If the light is on while certain DIC
messages display, this indicates
that the TCS and StabiliTrak
systems are not working or are
disabled.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak
system have been disabled. Check
the DIC messages to determine
which feature(s) is no longer
functioning and whether it is
because of the driver turning off the
feature(s), or because the system is
not working properly and the vehicle
requires service.
If the TCS is disabled, wheel spin is
not limited. If the StabiliTrak system
is disabled, the system does not aid
in maintaining directional control of
the vehicle.If the indicator/warning light is on
and flashing, the TCS or the
StabiliTrak system is actively
working.
See
StabiliTrak
®System on
page 9‑36 andTraction Control
System (TCS) on page 9‑35 for
more information.
See Ride Control System Messages
on page 5‑32 for more information
on the messages associated with
this light.
Engine Coolant
Temperature Warning
Light
For eAssist vehicles, this light
comes on briefly while starting the
vehicle. If it does not, have the vehicle
serviced by the dealer. If the system
is working normally, the indicator
light goes off.
Notice:
Driving with the engine
coolant temperature warning light
on could cause the vehicle to
overheat. See Engine Overheating
on page 10‑20. The vehicle's
engine could be damaged, and it
might not be covered by the
vehicle warranty. Never drive with
the engine coolant temperature
warning light on.
The engine coolant temperature
warning light comes on when the
engine has overheated.
If this happens, pull over and turn
off the engine as soon as possible.
See Engine Overheating on
page 10‑20.
