SONAR SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the sonar function. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system, including
reduced performance or a false acti-
vation.
. The system is not designed to pre-
vent contact with small or moving
objects.
. The system will not detect small
objects below the bumper, and may
not detect objects close to the bum-
per or on the ground.
. The system may not detect the
following objects:
— Fluffy objects such as snow, cloth, cotton, grass or wool.
— Thin objects such as rope, wire or chain. — Wedge-shaped objects.
. If your vehicle sustains damage to the
bumper fascia, leaving it misaligned
or bent, the sensing zone may be
altered causing inaccurate measure-
ment of objects or false alarms.
CAUTION
Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
System temporarily unavailable
When the amber markers are displayed at
the corners of the vehicle icon and the
function cannot be activated from the
Parking sonar settings menu (the setting
items are grayed out), the sonar system may
be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar (located on
the front and rear bumper fascia) free
from accumulations of snow, ice and dirt.
Do not scratch the surface of the sonar
when cleaning. If the sensors are cov-
ered, the accuracy of the sonar function

Upper vent system
When the “Upper Vent” key on the Climate
screen is touched, the air flow against the
driver’s or passenger’s upper body becomes
gentle. The indicator light on the key will
illuminate.
In this mode, air from the upper ventilator
flows in order to control the cabin tempera-
ture without blowing air directly on the
occupants. The upper vent system is useful when you
want the air conditioner to work quickly.
To turn the system off, touch the “Upper
Vent” key to turn the indicator light off.
Advanced Climate Control System
(if so equipped)
The Advanced Climate Control System
keeps the air inside of the vehicle clean,
using the automatic air circulation control
with the exhaust gas/outside odor detection
sensor and with ion control.

Automatic air recirculation control with the
exhaust gas/outside odor detection sensor:
The Advanced Climate Control system
comes with an exhaust gas detection/out-
side odor sensor. When the automatic air
circulation control is activated, the sensor

detects odors outside the vehicle such as
pulp or chemicals, and exhaust gas such as
gasoline or diesel. When such odors or gases
are detected, the display and the system
automatically change from the fresh air
mode to the recirculation mode.
When the automatic air circulation control
mode is on, for the first 5 minutes, the air
recirculation mode is selected to prevent
dust, dirt and pollen from entering the
vehicle and to clean the air inside of the
vehicle.
After 5 minutes, the sensor detects exhaust
gas and automatically alternates between
the air recirculation mode and the fresh air
mode.
NOTE:
The automatic air recirculation mode can be
activated under the following conditions.
.The air flow control is not in the wind-
shield defrosting mode (the indicator
light on the “
” front defroster but-
ton is turned off).
. The outside temperature is approxi-
mately 32 °F (0 °C) or above.
Ion control:
The Advanced Climate Control system unit
generates highly concentrated Plasmaclus-
ter
®ions into the air blown from the
ventilators to reduce odor absorbed into the interior trim and to suppress airborne
bacteria. The high-density Plasmacluster
®
ions also have a proven skin moisture
preserving effect.
The Plasmacluster
®icon on the Climate
screen indicates the status of the Plas-
macluster
®ion emission from the system
and changes with the amount of the air flow.
