For best results, clear all snow and
ice from the windshield before
defrosting.
A/C (For Non-Stop/Start
Vehicles) :Press to turn the air
conditioning on or off. If the fan is
turned off, the air conditioner will not
run and the indicator light may
turn off.
Press AUTO to return to automatic
operation and the air conditioner
runs 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 as
needed to defog the windshield
faster.
A/C (For Stop/Start Vehicles) :
Press to cycle between the off, eco,
and comfort air conditioning modes.
The indicator will be lit in comfort
and eco modes and turns off when
there is no A/C function. If the fan is
turned off, the air conditioner will not
run and the indicator light may
turn off.
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 as needed to defog the
windshield faster.
For comfort a/c, press A/C. The
indicator will turn amber.
For eco a/c, press A/C again. The
indicator will turn green. This 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 setting. This setting
allows higher humidity inside the
vehicle and window fogging before
the engine restarts.
Pressing
0during an auto stop
may restart the engine to prevent
window fogging. To reach comfort
levels quickly during an auto stop,
the engine will restart if the air
conditioner is off and AUTO or A/C
is selected. If temperature controls are adjusted
cooler during an auto stop, the
engine may restart to ensure that
comfort is reached.
L:
Press to turn on
recirculation. An indicator light
comes on. Air is recirculated to
quickly cool the inside of the vehicle
or prevent outside air and odors
from entering.
Auto Defog : The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. To turn Auto Defog off or
on, see “Climate and Air Quality”
under Vehicle
Personalization 0139.

190 Climate Controls
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter reduces dust, pollen, and other
airborne irritants from outside air
that is pulled into the vehicle. The
filter will need to be replaced
periodically. SeeMaintenance
Schedule 0326.
Using the climate control system
without an air filter installed is not
recommended. Water or other
debris could enter the system and
result in leaks or noises. Always
install a new filter when removing
the old filter.
For more information on filter
replacement, see your dealer.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.

208 Driving and Operating
AUTO STOP. SeeTachometer
0 116. When the brake pedal is
released or the accelerator pedal
pushed, the engine will restart.
Auto stop may be deactivated if:
. A minimum vehicle speed is not
reached.
. The engine or transmission is
not at the required operating
temperature.
. The outside temperature is not
in the required operating range,
typically below -10 °C (14 °F) or
above 50 °C (122 °F).
. The shift lever is in any gear
other than D (Drive).
. The battery has been recently
disconnected.
. The battery charge is low.
. The interior comfort level has not
reached the required level for
the climate control system or
defog settings. Use the eco
(green indicator on) air
conditioning mode for better
efficiency. See Dual Automatic
Climate Control System 0185. .
The auto stop time is greater
than two minutes.
Engine Heater
The engine coolant heater,
if equipped, can help in cold
weather conditions at or below −18 °
C (0 °F) for easier starting and better
fuel economy during engine
warm-up. Plug in the coolant heater
at least four hours before starting
the vehicle. An internal thermostat
in the plug end of the cord will
prevent engine coolant heater
operation at temperatures above
−18 °C (0 °F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The electrical
cord is on the driver side of the
engine compartment, between
the fender and the engine
compartment fuse block. Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly
3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
. Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection
function. An ungrounded
outlet could cause an
electric shock.
. Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension
cord in good operating

266 Vehicle Care
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem might not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
. Stops after high-speed driving.
. Idles for long periods in traffic.
. Tows a trailer.
If the overheat warning displays with
no sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the
highest fan speed. Open the
windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral), and let the
engine idle.
If the coolant temperature gauge is
no longer in the overheat zone, the
vehicle can be driven. Continue to drive the vehicle slowly for about
10 minutes. Keep a safe vehicle
distance from the vehicle in front.
If the warning does not come back
on, continue to drive normally and
have the cooling system checked
for proper fill and function.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
Overheated
Engine Protection Operating
Mode 0266.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
allows the vehicle to be driven to a
safe place in an emergency
situation. If an overheated engine
condition exists, an overheat
protection mode which alternates
firing groups of cylinders helps prevent engine damage. In this
mode, there is significant loss in
power and engine performance.
The engine coolant temperature
gauge indicates if an overheat
condition exists. Driving extended
distances and/or towing a trailer in
the overheat protection mode
should be avoided.
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid
