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.

REMOTE KEYLESS ENTRY SYSTEM
Revision: August 20072004 QX56

keyless power window down (open)

auto door lock operation
OPERATING PROCEDURE

When the keyfob is operated, the signal from the keyfob is sent and the remote keyless entry receiver
receives the signal and sends it to the BCM. The BCM only locks/unlocks the doors if the ID number
matches (remote control entry functions).

Using the keyfob, the transmitter sends radio waves to the remote keyless entry receiver, which then
sends the received waves to the BCM. Only if the ID number matches does the BCM lock/unlock the
doors (remote control door function).

Unless the key is inserted into the ignition key cylinder or one of the doors is opened within 1 minute after
the UNLOCK switch on the keyfob is pressed, all the doors are automatically locked (auto lock function).

When a door is locked or unlocked, the vehicle turn signal lamps flash and the horn sounds to verify oper-
ation (active check function).

When the key is in the ignition key cylinder (when the key switch is ON) and one of the doors is open, the
door lock function does not work even when the door lock is operated with the keyfob.

Keyfob ID set up is available.

If a keyfob is lost, a new keyfob can be set up. A maximum of 5 IDs can be set up simultaneously.
Remote Control Entry Functions
Operation Description

When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote
keyless entry receiver.

The received signal is sent to the BCM and compared with the registered ID number.

If the ID number matches, the BCM sends the lock/unlock signal to each door lock actuator.

When the door lock actuators receive this signal, each operates to lock/unlock its door.

BCM locks all doors with input of LOCK signal from keyfob.

When an UNLOCK signal is sent from keyfob once, driver's door will be unlocked.

Then, if an UNLOCK signal is sent from keyfob again within 5 seconds, all other doors will be unlocked.
Remote control entry operation conditions
Auto Lock Function
Operation Description

Unless the key is inserted into the ignition key cylinder, one of the doors is opened, or the keyfob is oper-
ated within 1 minute after a door lock is unlocked by keyfob operation, all the doors are automatically
locked.
The 1 minute timer count is executed by the BCM and after 1 minute, the BCM sends the lock signal to all
doors.
Lock operations are the same as for the remote control entry function.
Remote Control Automatic Back Door Function
Switching from all closed to all open

When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote
keyless entry receiver.

The received signal is sent to the BCM and compared with the registered ID number.

If the ID number matches, the BCM uses power window serial link communication to send the back door
open signal to the back door control unit.

When the back door control unit receives the back door open signal for 0.5 seconds, if the remote control
automatic back door operation enable conditions are met, the warning chime is sounded and the back
door unlock signal is sent to the back door latch using communication.
