work properly.
Interior Air Quality
If equipped, the Interior Air Quality display
indicates the concentration of PM2.5
(2.5 micron and smaller) pollution present in the interior air of the vehicle. The source of
this pollution is the environment
surrounding the vehicle. Your vehicle is
equipped with a cabin filter which cleans the
air and reduces this pollution anytime the
HVAC is on.
The displayed value is updated every few
seconds by a sensor in the vehicle’s interior.
Higher numbers indicate a higher level of
pollution in the air while lower numbers
indicate cleaner air. A reading of zero
indicates the pollution level is too low to be
read by the sensor.
The interior air quality level is displayed in
the application which can be opened from
the home screen. The interior air quality
level may also be continually displayed in
the lower right corner of the screen. This
can be turned on or off by selecting the
Settings menu, then Applications, and then
Air Quality.
The number scaling, colors, and categories
are set according to regional standards.
More information is available by touching
the screen within the Interior Air Quality
application. For more information on the
pollution scale in your region visit:

Caution
Cranking the engine for long periods of
time, by pressing ENGINE START/STOP
immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at
least 15 seconds between each try, to let
the cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor and hold it there, then press
ENGINE START/STOP for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the button
and the accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra gasoline
from the engine. Do not race the engine
immediately after starting it. Operate the engine and transmission gently until
the oil warms up and lubricates all
moving parts.
Stop/Start System
The Stop/Start system will shut off the
engine to help conserve fuel. It has
components designed for the increased
number of starts.
{Warning
The automatic engine Stop/Start feature
causes the engine to shut off while the
vehicle is still on. Do not exit the vehicle
before shifting to P (Park). The vehicle
may restart and move unexpectedly.
Always shift to P (Park), and then turn
the ignition off before exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied and the vehicle
is at a complete stop, the engine may turn
off. When stopped, the tachometer displays
AUTO STOP. See Tachometer092. When the
brake pedal is released or the accelerator
pedal is pressed, the engine will restart. To maintain vehicle performance, other
conditions may cause the engine to
automatically restart before the brake pedal
is released.
Auto Stops may not occur and/or auto
restarts may occur because:
.The climate control settings require the
engine to be running to cool or heat the
vehicle interior.
.The vehicle battery needs to charge.
.The vehicle battery has recently been
disconnected.
.Minimum vehicle speed has not been
reached since the last Auto Stop.
.The accelerator pedal is pressed.
.The engine or transmission is not at the
required operating temperature.
.The outside temperature is not in the
required operating range.
.The vehicle transmission is shifted out of
D (Drive) to any gear other than P (Park).
.Certain driver modes have been selected.
See
Driver Mode Control 0212.
