WARNING
.The heater and air conditioner oper-
ate only when the engine is running.
. Never leave children or adults who
would normally require the support
of others alone in the vehicle. Pets
should not be left alone either. They
could unknowingly activate switches
or controls and inadvertently become
involved in a serious accident and
injure themselves. On hot, sunny
days, temperatures in a closed vehicle
could quickly become high enough to
cause severe or possibly fatal injuries
to people or animals.
. Do not use the recirculation mode for
long periods as it may cause the
interior air to become stale and the
windows to fog up.
. Do not adjust the heating and air
conditioning controls while driving so
that full attention may be given to
vehicle operation.
The heater and air conditioner operate when
the engine is running. The air blower will
operate even if the engine is turned off and
the ignition switch is placed in the ON
position. NOTE:
.
Odors from inside and outside the
vehicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the ventilators.
. When parking, set the heater and air
conditioner controls to turn off air
recirculation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.
. Vehicles with an automatic climate con-
trol system will automatically adjust the
passenger compartment to be the set
appropriate temperature when the re-
mote engine start feature (if so
equipped) is used.
HEATER AND AIR CONDITIONER

The Plasmacluster®icon on the climate
screen indicates the status of the Plas-
macluster
®ion emission from the system

on/off. (See “Heated steering wheel”
(P.2-44).)
. Auto Steering Wheel Heater
The automatic control mode for the
steering wheel heater can be turned
on/off. When this item is turned on, the steering wheel heater will turn on auto-
matically if the temperature inside the
vehicle compartment is low at the time
when the ignition switch is turned on.
Regardless of the temperature, the
steering wheel heating will turn off after
30 minutes.
If the steering wheel heater is manually
turned on/off by touching [Steering
Wheel Heater] on the climate settings
screen, the automatic steering wheel
heating control mode will be canceled
and the system will return to the manual
mode.
