Oil Life :Displays an estimate of
the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See Engine Oil Messages 0134.
The oil should be changed as soon
as possible. See Engine Oil0228.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is

Fuel Range and Instantaneous
Fuel Economy : Displays the
approximate distance the vehicle
can be driven without refueling.
LOW will be displayed when the
vehicle is low on fuel. The fuel
range estimate is based on an
average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank. Displays the current fuel economy in
either liters per 100 kilometers
(L/100 km) or miles per
gallon (mpg). This number reflects
only the approximate fuel economy
that the vehicle has right now and
changes frequently as driving
conditions change.
Oil Life :
Displays an estimate of
the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.

best AFE, a several second press
and hold of
Vwill reset the best
value. The best value will show
“- - -“ until the selected distance has
been traveled. The display provides
feedback on how current driving
behavior in the bar graph affects the
running average in the left display
and how well recent driving
compares to the best that has been
achieved.
Fuel Used and Timer : Displays
the approximate liters (L) or
gallons (gal) of fuel that have been
used since last reset. The fuel used
can be reset by pressing the

Economy Trend : Displays history
of the Average Fuel Economy from
the last 50 km (30 miles). Each bar
represents about 5 km (3 miles) of
driving. The fuel economy will range
from 0 –15 L/100 km (0 –50 mpg).
During driving the bars will shift to
always reflect the most recent
distance on the right side. This
display cannot be reset. Eco Index :
The bar graph on the
left hand side provides feedback on
the efficiency of current driving
behavior. The graph shows
a percentage value that is based on
current fuel consumption compared
to what is expected from the vehicle
with good and bad driving habits.
Each box represents 10%, with all
boxes filled being 100%. More
economical driving will result in
being in the ECO box.
Instantaneous Fuel Economy is also
shown on right hand side. This
display cannot be reset.

Climate Control Influence on
eAssist Operation and Fuel
Economy (If Equipped)
The climate control system depends
on other vehicle systems for heat
and power input. Certain climate
control settings can lead to higher
fuel usage and/or fewer auto stops.
The following climate control
settings use more fuel:
. Comfort air conditioning mode.
. The defrost mode.
. Extreme temperature settings,
such as 15 °C (60 °F) or 32 °C
(90 °F).
. High fan speed settings. To help reduce fuel usage:
.
Use the full automatic control as
described under “Automatic
Operation.”
. Use eco air conditioning, instead
of the comfort air conditioning.
. Select a temperature setting that
is higher in hot weather and
lower in cold weather.
. Turn off the air conditioning
when it is not needed.
. Only use defrost to clear the
windows.
Automatic Operation
The system automatically controls
the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
When the AUTO indicator light is
on, the system is in full automatic
operation. If the air delivery mode,
fan speed, recirculation, or air
conditioning setting is adjusted, the
AUTO indicator turns off and the
selected settings will appear on the
display. To place the system in
automatic mode:
1. Press AUTO.
2. Set the temperature. Allow the system time to stabilize. Adjust
the temperature as needed for
best comfort.
To improve fuel efficiency and to
cool the vehicle faster, recirculation
may be automatically selected in
warm weather. The recirculation
light will not come on when
controlled automatically. Press
@
to manually select recirculation;
press it again to select outside air.
Q/R(Driver and Passenger
Temperature Controls) : The
temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the temperature.
SYNC (Synchronized
Temperature) : Press to link all
climate zone settings to the driver
settings. The SYNC indicator light
will turn on. When the passenger
settings are adjusted, the SYNC
indicator light is off.

Manual Operation
O(Power) :Press to turn the fan off
or on.
Q 9 R(Fan Control) : Press to
increase or decrease the fan speed.
The fan speed setting appears on
the main display. Pressing either
button cancels automatic fan control
and the fan is controlled manually.
Press AUTO to return to automatic
operation.
Air Delivery Mode Controls :
Press
X,Y, or[to change the
direction of the airflow. Air delivery
mode settings can be combined.
The current mode appears in the
display screen. Changing the air
delivery mode cancels automatic
operation and the system goes into
manual mode. Press AUTO to
return to automatic operation.
To change the current mode, press
one or more of the following:
X(Defog) : Air is directed to the
windshield and side window vents.
Y(Vent) : Air is directed to the
instrument panel outlets.
[(Floor) : Air is directed to the
floor outlets.
0MAX (Defrost) : Clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield.
For best results, clear all snow and
ice from the windshield before
defrosting.
For eAssist vehicles that have the
auto defog feature, auto stops can
occur in defrost mode. In this mode,
the auto stops are shorter and less
frequent than other air delivery
modes to prevent instant fogging.
A/C (Comfort Air Conditioning) :
Press to turn the air conditioning
system on or off. If the climate
control system is turned off or the
outside temperature falls below
freezing, the air conditioner will
not run.
Pressing this button cancels
automatic air conditioning and turns
off the air conditioner. Press AUTO
to return to automatic operation and
the air conditioner runs
automatically as needed. When the indicator light is on, the air
conditioner runs automatically to
cool the air inside the vehicle or to
dry the air needed to defog the
windshield faster.
For eAssist vehicles, an auto stop
may occur if the climate control
system determines the A/C
compressor can be shut off and still
maintain comfort levels with minimal
windshield fogging.
ECO A/C (For eAssist Vehicles) :
Press to cycle between the off, eco,
and comfort air conditioning modes.
The indicator will be lit green in eco,
amber in comfort, and turns off
when there is no A/C function. If the
fan is turned off the A/C will not run.
The eco A/C setting balances fuel
economy and air conditioning
comfort. In warm weather
conditions, auto stops may occur
more frequently and the vehicle
interior may be warmer as
compared to the comfort air
conditioning. This setting allows
higher humidity inside the vehicle
and window fogging before the
engine restarts.
