The traction off light comes on when the
Traction Control System (TCS) has been
turned off by pressing and releasing the
TCS/StabiliTrak button.
This light and the StabiliTrak OFF light come
on when StabiliTrak is turned off.
If the TCS is off, wheel spin is not limited.
Adjust driving accordingly.
StabiliTrak OFF Light
This light comes on briefly while starting
the vehicle. If it does not, have the vehicle
serviced by your dealer.
This light comes on when the StabiliTrak
system is turned off. If StabiliTrak is off, the
Traction Control System (TCS) is also off.
If StabiliTrak and TCS are off, the system
does not assist in controlling the vehicle.
Turn on the TCS and the StabiliTrak systems,
and the warning light turns off.See
Traction Control/Electronic Stability
Control 0166.
Traction Control System (TCS)/
StabiliTrak Light
This light comes on briefly when the vehicle
is started.
If the light does not come on, have the
vehicle serviced by your dealer. If the
system is working normally, the indicator
light turns off.
If the light is on and not flashing, the TCS,
and potentially the StabiliTrak/Electronic
Stability Control system have been disabled.
If the indicator/warning light is on and
flashing, the TCS and/or the StabiliTrak/ESC
system is actively working.
Tire Pressure Light
For vehicles with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the vehicle is started. It provides
information about tire pressures and
the TPMS.
When the Light is On Steady
This indicates that one or more of the tires
are significantly underinflated.
A message in the Driver Information Center
(DIC) may also display. Stop as soon as
possible, and inflate the tires to the pressure
value shown on the Tire and Loading
Information label.
When the Light Flashes First and Then Is On
Steady
This indicates that there may be a problem
with the TPMS. The light flashes for about
one minute and stays on steady until the
vehicle is off. This sequence repeats each
time the vehicle is started.

If the Programmable Charging system is
consistently disabled, see your dealer.
Energy Information
To view Energy Detail, Range Impacts, and
Efficiency History, touch Energy on the
infotainment display, and then touch
Information. Touch
horkto go to the next
screen.
Energy Detail
This screen displays how energy is being
used since the last time the high voltage
battery was fully charged. It includes Driving and Accessories, Climate Settings, and
Battery Conditioning. The circle graph
displays these percentages. Energy Used and
Distance Traveled are also displayed.
Range Impacts
This screen provides an estimate of the
factors that influence energy usage since the
last full charge of the high voltage battery.
Each factor is evaluated for energy gains or
losses, and the total equivalent distance is
indicated by the value on the right side of
the screen. All values are reset after a
complete charge.
.Technique
includes speed, acceleration,
and braking. Lower speeds will increase
electric vehicle technique miles, while
higher speeds will reduce them.
.Terrain includes road conditions, such as
hills, rain, and snow. External factors like
wind will also positively or negatively
impact Terrain. Low tire pressure will
worsen Terrain performance.
.Climate Settings includes how the heating
and air conditioning are used. Using Fan
Only settings will help reduce climate
setting losses. See “Climate Controls”.
.Outside Temperature includes the effect
that hot or cold ambient temperature has
on the battery performance and
propulsion system efficiency.
The individual factors provide an
understanding of how energy usage is
different from day to day, even when
traveling the same route.

available for your particular vehicle. Some
items may not be turned on by default but
can be turned on through the Options app.
See “DIC Info Page Options” earlier in this
section. Trip and Average Electrical Energy
Economy :
The Trip display shows the
current distance traveled, in either
kilometers (km) or miles (mi), since the trip
odometer was last reset. The trip odometer
can be reset by pressing and holding
V
while this display is active.
The Average Electrical Energy Economy
display shows the approximate average kWh
per 100 kilometers (kWh/100 km) or miles
per kWh. This number is calculated based on
the number of kWh/100 km recorded since
the last time this menu item was reset. This
number reflects only the approximate
average electrical energy economy that the
vehicle has right now, and will change as
driving conditions change. The Average
Electrical Energy Economy can be reset
along with the trip odometer by pressing
and holding
Vwhile this display is active.
Tire Pressure : Shows the approximate
pressures of all four tires. Tire pressure is
displayed in either kilopascal (kPa) or in
pounds per square inch (psi). If the pressure
is low, the value for that tire is shown in
amber.
Average Speed : Shows the average speed
of the vehicle in kilometers per hour (km/h)
or miles per hour (mph). This average is

Vehicle Messages
Messages displayed on the DIC indicate the
status of the vehicle or some action that
may be needed to correct a condition.
Multiple messages may appear one after
another. The messages that do not require
immediate action can be acknowledged and
cleared by pressing
V. The messages that
require immediate action cannot be cleared
until that action is performed.
All messages should be taken seriously;
clearing the message does not correct the
problem.
If a SERVICE message appears, see your

Propulsion Power Messages
PROPULSION POWER IS REDUCED
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 stays on, or displays repeatedly,
the vehicle should be taken to your dealer
for service as soon as possible.
This message is commonly displayed when
the high voltage battery charge level is low.
The vehicle is limiting power to maximize
range.
This message can display when the vehicle
is parked during extreme cold conditions
without being plugged in. While driving the

positions (1), and the maximum vehicle
capacity weight (2) in kilograms and
pounds.
The Tire and Loading Information label
also shows the tire size of the original
equipment tires (3) and the
recommended cold tire inflation
pressures (4). For more information on
tires and inflation seeTires0216 and
Tire Pressure 0221.
There is also important loading
information on the Certification label.
It may show the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle
Weight Rating (GAWR) for the front and
rear axle. See “Certification Label” later
in this section.
“Steps for Determining Correct Load
Limit–
1.Locate the statement "The combined
weight of occupants and cargo
should never exceed XXX kg or
XXX lbs." on your vehicle’s placard.
2.Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3.Subtract the combined weight of the
driver and passengers from XXX kg
or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For example,
if the "XXX" amount equals 1400 lbs.
and there will be five 150 lb
passengers in your vehicle, the
amount of available cargo and
luggage load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lbs.)
5.Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
6.If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this reduces the available cargo and
luggage load capacity of your
vehicle.”
This vehicle is neither designed nor
intended to tow a trailer.
Example 1
1.Vehicle Capacity Weight for
Example 1 = 453 kg (1,000 lbs).
2.Subtract Occupant Weight @
68 kg (150 lbs) × 2 = 136 kg
(300 lbs).
3.Available Occupant and Cargo
Weight = 317 kg (700 lbs).
