Important Information about
Electric Vehicle Charging
.Charging an electric vehicle
can stress a building’s
electrical system more than
a typical household
appliance.
.Charge cord limits can vary
from vehicle to vehicle, and
increased charging rates can
stress a building’s electrical
system.
.Before plugging into any
electrical outlet, have a
qualified electrician inspect
and verify the electrical
system (electrical outlet,
wiring, junctions, andprotection devices) for
heavy-duty service at a
12 amp continuous load.
.Electrical outlets may wear
out with normal usage or
may be damaged over time,
making them unsuitable for
electric vehicle charging.
.Check the electrical outlet/
plug while charging and
discontinue use if the
electrical outlet/plug is hot,
then have the electrical
outlet serviced by a qualified
electrician.
.When outdoors, plug into an
electrical outlet that is
weatherproof while in use.
.Mount the charging cord to
reduce strain on the
electrical outlet/plug.
.Do not place the charge cord
in a position where it is
expected to be submerged
in water.
{Danger
Improper use of portable
electric vehicle charge cords
may cause a fire, electrical
shock, or burns, and may
result in damage to
property, serious injury,
or death.
.Do not use extension
cords, multi-outlet power
strips, splitters, grounding
adaptors, surge
protectors, or similar
devices.
.Do not use an electrical
outlet that is worn or
damaged, or will not hold
the plug firmly in place.
.Do not use an electrical
outlet that is not properly
grounded.
.Do not use an electrical
outlet that is on a circuit
with other electrical loads.

REDUCED
ACCELERATION DRIVE
WITH CARE
This message displays when
the vehicle's propulsion power
is reduced. A reduction in
propulsion power can affect
the vehicle's ability to
accelerate. If this message is
on, but there is no observed
reduction in performance,
proceed to your destination.
Under certain conditions, 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.
Anytime this message stayson, or displays repeatedly, the
vehicle should be taken to
your dealer for service as
soon as possible.
This message can be displayed
when the high voltage battery
charge level is low. The vehicle
is limiting power to maximize
range.
Under certain operating
conditions propulsion will be
disabled. Try restarting after
the vehicle has been off for
two minutes.
PROPULSION POWER
REDUCED DUE TO
TEMPERATURE
This message displays when
the vehicle is on, the battery
temperature is low, and when
the vehicle’s performance is
limited. The duration of the
limited vehicle performance
depends, in part, on the high
voltage battery charge level.
If the high voltage battery
charge level is relatively high,
as the vehicle is driven, the

Cadillac Lyriq Owner Manual (GMNA-Localizing-U.S./Canada-15644413) -

battery temperature will
increase, and the vehicle will
return to normal operation.
If the high voltage battery
charge level is relatively low
the vehicle will not return to
normal operation until
charged.
Keep the vehicle plugged in,
even when fully charged, to
keep the high voltage battery
temperature ready for the
next drive. This is important
when outside temperatures
are extremely hot or cold.

REDUCED ACCELERATION
DRIVE WITH CARE :The
accelerator pedal response is
reduced and the remaining
range value changes to LOW,
charge the vehicle
immediately. See Propulsion
Power Messages 0135.
OUT OF ENERGY, CHARGE
VEHICLE NOW : The battery
charge is fully depleted. The
vehicle will slow to a stop.
Brake and steering assist will
continue operating. Once
stopped, turn the vehicle off.
Plug-In Charging
Plug-in charge times vary
based on the battery
condition, charge level, and the
outside temperature. See
Charging 0123 for charge
mode selection.
Do not allow the vehicle to
remain in temperature
extremes for long periods
without being driven or
plugged in. When
temperatures are below 0 °C (32 °F) and above 32 °C (90 °F),
plug in the vehicle to maximize
high voltage battery life.
In extreme temperature
conditions, a full charge will
take additional time.
It is normal to hear fans,
pumps, and electrical devices
clicking while the vehicle is
turned off and charging.
The vehicle does not require
indoor charging area
ventilation before, during,
or after charging.
The vehicle cannot be driven
while the charge cord is
plugged into the vehicle.
Caution
To avoid damage to the
vehicle, make sure the
charging cord plug is in good
condition, is not worn or
damaged, and is connected
securely to the vehicle's
charging port. If vehicle
charging is intermittent,
(Continued)
Caution (Continued)
disconnect the cord and
inspect for damage. An
excessively worn or
damaged AC or DC charging
cord plug may result in an
intermittent connection and
potential damage to the
vehicle's charging port.
There are several infotainment
screens that will display
depending on the current
charging status. See Charging
0 123.
Charging Override
A CHARGING OVERRIDE/
INTERRUPTION OCCURRED

.Automatic Emergency
Braking (AEB)
.Front Pedestrian
Braking (FPB)
If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a
trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend
out from the back of the
vehicle do not move further
back when a trailer is towed.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive
as the vehicle itself. Become
familiar with handling and
braking of the combination by
driving on a level road surface
before driving on public roads. The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment
0303. If the trailer
has electric brakes, start the
combination moving and then
manually apply the trailer
brake controller to check the
trailer brakes work. During the
trip, occasionally check that
the cargo and trailer are
secure and that the lamps and
any trailer brakes are working.
Towing with a Stability
Control System
When towing, the stability
control system might be
heard. The system reacts to
vehicle movement caused by
the trailer, which mainly occurs during cornering. This is
normal when towing heavier
trailers.
Following Distance
Stay at least twice as far
behind the vehicle ahead as
you would when driving
without a trailer to help to
avoid heavy braking and
sudden turns.
Passing
More passing distance is
needed when towing a trailer.
The combination of the vehicle
and trailer will not accelerate
as quickly and is much longer
than the vehicle alone. It is
necessary to go much farther
beyond the passed vehicle
before returning to the lane.
Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the
steering wheel with one hand.
To move the trailer to the left,
move that hand to the left. To
