Noise InspectionEKS007KK
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.

TIRE PRESSURE

Pressure indication in psi on the screen indicates that the
pressure is being measured. After a few trips, the pressures for
all four tires will be displayed.

The order of tire pressure figures displayed on the screen does
not correspond with the actual order of tire position.

Tire pressure rises and falls depending on the heat caused by
the vehicle's traveling condition and the temperature.

In case of low tire pressure, the low tire pressure warning light
will come on and/or a warning is displayed on the screen.

FLAT TIRE – very low tire pressure.
NOTE:

In a case of FLAT TIRE pressure, interrupt screen is not shown on the display.

On the screen of TIRE PRESSURE, "FLAT TIRE Check All tires" is displayed.
WARNING INDICATIONS
Warning signal (Door switch signal) is received from BCM through
CAN communication line.
