Messages
PARK ASSIST OFF
This message displays when the
park assist system has been turned
off or when there is a temporary
condition causing the system to be
disabled. SeeUltrasonic Parking
Assist on page 9‑42.
SERVICE PARKING ASSIST
This message displays if there is a

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 at a reduced
speed 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
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
PROPULSION POWER IS
REDUCED message and the
malfunction indicator lamp are on
should the vehicle be taken to the
dealer for service.
While climbing the grade with this
message displayed, the vehicle
speed may be reduced until the
engine can recover the battery state
of charge to a normal level. See
“Mountain Mode”
underDriver
Selected Operating Modes on
page 9‑25.

will display a screen with inactive
fuel and battery gauges. See
Starting and Stopping the Vehicle

A. Charge Level Button
B. Charge Level Indicators
C. Charge Cord Status Indicators
D. Vehicle Plug
E. Wall Plug A portable charge cord used to
charge the vehicle high voltage
battery is stored under the rear
luggage compartment.
{WARNING
There is a risk of electric shock
that may cause personal injury or
death. Do not use the charge
cord if any part of the charge cord
is damaged. Do not open or
remove the charge cord cover.
Service by qualified personnel
only. Connect the charge cord to
a properly grounded outlet with
cords that are not damaged.
The charge cord used to charge the
vehicle is a high‐powered electrical
device. During normal operation, the
AC wall plug of the charge cord may
feel warm. The AC wall plug must fit
tightly into an AC outlet that is in
good condition.
{WARNING
Using the charge cord with a
worn or damaged AC outlet may
cause burns or start a fire.
Periodically, check the AC wall
plug and charge cord while the
vehicle is charging. If the AC wall
plug feels hot, unplug the charge
cord and have the AC outlet
replaced by a qualified electrician.
Replace the charge cord if the AC
wall plug or cord are damaged.
Do not use an AC outlet that is
worn or damaged.

{WARNING
An extension cord should not be
used to charge the vehicle. Use
of an extension cord may
increase the risk of electric shock
or other hazards.
If an extension cord is used
because of limited access to
120V AC power, use the following
safeguards:
The 120V AC outlet should be
GFCI protected.
The extension cord should be:
.GFCI protected.
.12 or 14 gage, 3 conductor.
.Rated for outdoor.
{WARNING
Multi‐outlet power strips, surge
protectors, or similar devices
could increase the risk of
electrical shock or other hazards.
Do not use these types of devices
with the charge cord.
Charge Cord Status Indicators
The charge cord status indicators
illuminate green or flashing red to
identify the charge cord status.
When both indicators are green, the
vehicle can be charged. If any
indicators are flashing red, the
charge cord will not permit vehicle
charging.
A flashing red AC PRESENT (A)
indicates the AC voltage is out of
range.
Flashing red AC PRESENT (A) and
FAULT (B) indicate the AC outlet
does not have a proper safety
ground. Charging is not permitted
for safety reasons. The AC outlet
must be repaired or another outlet
source should be used.
A flashing red FAULT (B) indicates a
charge cord fault. The charge cord
will attempt to reset automatically.
If the flashing red FAULT (B)
continues for more than
30 seconds, unplug the charge cord
from the wall to reset. If the fault
remains, see your dealer for
service.

Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean
and avoid problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed by
the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change, can
help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must not be used in
vehicles that were not designed for
those fuels.
Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty. Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
spark plug life and affect emission
control system performance. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.

Vehicle Care 10-21
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Assistance Program on
page 13‑6.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the vehicle
and have the vehicle serviced.
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, be sure to read
the manufacturer's instructions
before use. If operating the vehicle
in an area where the temperature
may fall below freezing, use a fluid
that has sufficient protection against
freezing.
Adding Washer Fluid
The WASHER FLUID LOW ADD
FLUID message will appear on the
Driver Information Center (DIC)
when the fluid level is low. See
Driver Information Center (DIC) on
page 5‑45 for more information.
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview on
page 10‑8 for reservoir location.
