Climate Control Status Display
The climate control status display

Climate Control Influence on
Fuel Economy
The climate control system depends
on other vehicle systems for heat and
power input. Certain climate control
settings can lead to higher fuel usage.
The following climate control settings
use more fuel:
.MAX air conditioning mode
.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.”
.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.

following four functions to heat or
cool the vehicle to the desired
temperature:
.Fan Speed
.Air Delivery Mode
.Air Conditioning
.Recirculation
When the AUTO indicator light is lit,
all four functions are operating
automatically. Each function can be
manually set and the selected setting
will be shown. This cancels full

To place the system in
automatic mode: 1. Press AUTO.
2. Set the driver and passenger temperature. To find your comfort setting, start
with 22 °C (72 °F) and allow the
system time to stabilize. Then
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 automatically controlled.
Press
@to manually select
recirculation; press it again to select
outside air.
Do not cover the solar sensor on the

during remote start based on cold
ambient conditions. The rear defog
indicator light does not come on
during a remote start.
If equipped, the heated seats will turn
on if it is cold outside or the
ventilated seats will turn on if it is hot
outside. The heated and ventilated
seat indicator lights may not come on
during a remote start. If equipped, the
heated steering wheel will come on in
a remote start if it is cold outside. The
heated steering wheel indicator light
may not come on.
Ionizer :If equipped with an ionizer,
this feature helps to clean the air
inside the vehicle and remove
contaminants such as pollen, odors,
and dust. If the climate control
system is on and the ionizer is
enabled, the ionizer status indicator
will be lit on the climate control
display. To turn the ionizer on or off,
see Climate and Air Quality under
Vehicle Personalization 0120.Sensors
The solar sensor, located in the
defrost grille in the middle of the
instrument panel, monitors the solar
heat. Do not cover the solar sensor or
the system will not work properly.
There is also an exterior temperature
sensor behind the front grille. This
sensor reads the outside air
temperature and helps maintain the
temperature inside the vehicle. Any
cover on the front of the vehicle,
could cause a false reading in the
displayed temperature. The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the outlet temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the sun.
The recirculation mode will also be
used as needed to maintain cool
outlet temperatures.
Afterblow Feature
If equipped, under certain conditions,
the fan may stay on or may turn on
and off several times after you turn
off and lock the vehicle. This is
normal.

210 DRIVING AND OPERATING
.Replace the vehicle's tires with the
same TPC Spec number molded into
the tire's sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and
can take your focus from the task of
driving. Exercise good judgment and
do not let other activities divert your
attention away from the road. Many
local governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep your
eyes on the road, keep your hands on
the steering wheel, and focus your
attention on driving.
.Do not use a phone in demanding
driving situations. Use a hands-free
method to place or receive
necessary phone calls.
.Watch the road. Do not read, take
notes, or look up information on
phones or other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle
features before driving, such as
programming favorite radio stations
and adjusting climate control and
seat settings. Program all trip
information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to
the floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier
or restraint.
.Avoid stressful conversations while
driving, whether with a passenger or
on a cell phone.
{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Refer to the infotainment section for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first step
in driving defensively is to wear the
seat belt. See Seat Belts040.
.Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless and
make mistakes. Anticipate what
they may do and be ready.
.Allow enough following distance
between you and the driver in front
of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated with
impaired driving is a global tragedy.
{Warning
Drinking alcohol or taking drugs
and then driving is very dangerous.
Your reflexes, perceptions,
attentiveness, and judgment can be
affected by even a small amount of
alcohol or drugs. You can have a
