remaining transmitters must also be
reprogrammed. Any lost or stolen
transmitters will no longer work
once the new transmitter is
programmed. Each vehicle can
have up to eight transmitters
matched to it. Programming with Recognized
Transmitters
A new transmitter can be
programmed to the vehicle when
there are two recognized
transmitters. To program, the vehicle
must be off and all of the
transmitters, both currently
recognized and new, must be in the
vehicle.
1. Place the two recognized transmitters in the cupholder.
2. Remove the key lock cylinder cap on the driver door handle.
See Door Locks 040. Insert
the vehicle key of the new
transmitter into the key lock

106 Instruments and Controls
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the propulsion system is
started to indicate they are working.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.
Instrument Cluster
The instrument cluster displays a
preview of information that includes
electric range, charging, odometer,and battery status. This happens
upon entry when the driver door is
opened before starting the vehicle.
The CHARGING OVERRIDE/
INTERRUPTION OCCURRED
message may display to indicate
that a charging override or
interruption has occurred due to one
or more of the following events:
.
Override of the charge settings
by the owner using OnStar.
. Unintended interruption of AC
power at the vehicle's
charge port.
. Interruption of charging by the
utility company using OnStar as
authorized by the vehicle owner.

Propulsion Power
Messages
PROPULSION POWER IS
REDUCED
This message displays when the
propulsion power is reduced and
can affect the ability to accelerate.
If this message is on, but there is no
reduction in performance, proceed
to your destination. The
performance may be reduced the next time the vehicle is driven. The
vehicle may be driven while this
message is on, but maximum
acceleration and speed may be
reduced. If this message stays on
when the malfunction indicator lamp
is on, the vehicle should be taken to
your dealer for service as soon as
possible.
This message can display when the
vehicle is parked during extreme
cold conditions without plugging in.
While driving the vehicle with this
message displayed, the vehicle
speed may be reduced until the high
voltage battery is conditioned.
This message can display when
driving in mountainous terrain
without using Mountain Mode or by
not entering Mountain Mode soon
enough to build a sufficient battery
charge reserve before climbing
steep grades. This is normal
operation to protect the high voltage
battery. Only if both the

Refer to the replacement number
shown on the original battery label
when a new 12-volt battery is
needed. The vehicle has an
Absorbed Glass Mat (AGM) 12-volt
battery. Installation of a standard
12-volt battery will result in reduced
12-volt battery life.
When using a 12-volt battery
charger on the 12-volt AGM battery,
some chargers have an AGM
battery setting on the charger.
If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts. Follow the charger
manufacturer's instructions.
