lead to higher fuel usage and/or
fewer auto stops.
The following are climate control
settings that use more fuel:
.Comfort 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.”
.Use eco air conditioning, instead
of the comfort air conditioning.

the vehicle or to dry the air as
needed to defog the windshield
faster. A/C (Comfort/Eco Air
Conditioning) (For Stop/Start
Vehicles):
Press to cycle between
the off, eco, and comfort air
conditioning modes. The indicator

conditioning setting. This setting
allows higher humidity inside the
vehicle and window fogging before
the engine restarts.
Pressing the
0button during 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.

cooler by more than 1°C (1°F)
during an auto stop, the engine will
restart to ensure that comfort is
reached.
L(Recirculation): Press to turn
on recirculation. An indicator light
comes on. Air is recirculated to

9-20 Driving and Operating
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
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
may be injured. Because the
vehicle has the auto engine stop/
start feature, the vehicle's engine
might seem to be shut off;
however, once the brake pedal is
released, the engine will start up
again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.If equipped with the 2.5L L4 Engine,
the vehicle has a fuel saving stop/
start system to shut off the engine to
help conserve fuel.
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
Tachometer on
page 5-12. 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 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 on
page 8-3.
.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).
