Interior
Located above the windshield in the center is the overhead console that contains the uni-
versal remote switch panel, interior lighting/map panel, sunroof switch and grille for the tele-
phone hands-free microphone. The light panel contains a single bulb which is controlled by
the ZKE, as well as two map reading lamps. The switch provides a ground signal which the
GM recognizes as a request to either turn the interior lights on or off. If the switch is held >
3 seconds, the lights are switched off in the work shop mode as on other models.
Incorporated into the overhead con-
sole, behind the universal remote
switch, is a sunglass storage com-
partment

System Operation
The seat backs are adjusted from the two different locations as follows:
• The switches in the interior light housing receive operating power through the seat back
relay when the ignition is switched on KL 15. The GM controls the operation of the relay
and the switches provide the ground.
• The switches in the “D” pillar receive KL 30 and allow seat back adjustment whenever
the rear tailgate is opened to gain access to the switches.
• The adjustment motors receive power and ground directly from the switches.

Climate Control Systems (IHKR/IHKA)
Two climate control systems are offered on the X5, the manual IHKR system is standard
equipment on the 3 liter X5 and the IHKA system is available as an option. The IHKR is a
new system for US production and the IHKA is taken from the E39 vehicles.
Condenser/Receiver Dryer
The X5 incorporates a new design air conditioning condenser/receiver dryer for both the
manual (IHKR) and the automatic (IHKA) systems. The dryer cartridge and condenser are
one component with the dryer integrated on the left side. The dryer cartridge contains a
replaceable filter screen and dryer unit.
The condenser is partitioned which divides the condenser into cooling sections. The hot
refrigerant flows across the condenser and into the dryer through inlet holes at the lower
1/3 section of the cooling fins. After the refrigerant passes through the dryer it returns to
the evaporator through the outlet hole and bottom 1/3 section of the condenser.

Climate Control System (IHKR)
The manual system is controlled through the use of bowden cables for air distribution and
electronic control for temperature regulation and blower speed. One stepper motor is used
for the fresh/recirculated air intake.
The IHKR incorporates the following features:
• Fresh air intake grilles integrated into the hood - the fresh air passes through the single
micro filter installed in the center of front bulkhead.
The air then passes through the air duct, which is bolted to the bulkhead, and enters the
heater - A/C unit through the non-return flaps.
