button to turn on both systems.
See Traction Control/Electronic
Stability Control on page 9-33.
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-12.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10-47.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter. The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
1. Select OIL LIFE on the
DIC menu.
2. Press SELECT to start the OIL LIFE reset procedure.
3. The DIC menu will display “Are
you sure that you want to reset?”
Use SELECT to choose YES to
reset oil life or NO to exit and
return to the previous menu.
4. If YES is selected, the DIC menu will display RESET OIL LIFE for
a short time and then 100% OIL
LIFE will be displayed when the
oil life system is successfully
reset.
See Engine Oil Life System on
page 10-12.

1-26 In Brief
Optimal energy efficiency is
achieved with the heat, air
conditioning, and fan turned off.
Less energy is used at low fan
speeds. When using the fan:
.Fan Only is the most energy
efficient climate setting as long
as
0is not selected.
.ECO is for moderate air
conditioning and heater
operation and is the next most
energy efficient setting as long
as
0is not selected.
.Comfort provides the most
comfort but is the least energy
efficient.
Use the auto heated seat feature
instead of climate settings. Heating
the seat uses less energy than
heating the vehicle interior.
Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize the electric range by
utilizing electricity from the electrical
outlet. Engine Assisted Heating operation,
if equipped, can be personalized.
In hot weather, avoid parking in
direct sunlight or use sunshades
inside the vehicle.
Turn off the front and rear window
defog/defrost when they are no
longer needed.
Avoid driving with the windows open
at highway speeds.
See
Vehicle Personalization on
page 5-50.Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold.
Maintenance
Always keep the tires properly
inflated and the vehicle properly
aligned. The weight of excess cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
If fuel is not regularly used, consider
keeping the fuel tank only one-third
full. Excess fuel weight impacts
efficiency and range.
For fuel recommendations, see
Fuel
on page 9-53
Avoid unnecessary use of electrical
accessories. Power used for
functions other than propelling the
vehicle will reduce EV range.
Using a rooftop carrier will reduce
efficiency due to additional weight
and drag.

interfere with the operation of the
passenger sensing system. This
could either prevent proper
deployment of the passenger
airbag(s) or prevent the passenger
sensing system from properly
turning off the passenger airbag(s).

airbags, see Different Size Tires
and Wheels on page 10-55 for
additional important information.
If you have to modify your vehicle
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.
See Customer Assistance Offices
on page 13-3.Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See
Airbag Readiness Light on
page 5-14.
