Doors/Mirrors
The doors on the X5 incorporate side bars which serve as side impact protection without
the use of the metal hooks found on the sedans. The mirrors are aero style that includes
cascade lighting at the bottom of the mirror for vehicle entry at night. The lights are
switched on when the vehicle is unlocked to light the ground around the door.
Running boards, integrated into the rocker panels, provide ease of entry on the left and right
sides.

The door handles are similar in design to the E46
and pull out and upward for opening. Removal of
the handles is also similar to the E46.
There are no serviceable components on the
lock/latch. The assembly must be replaced as a
unit.
The lock cylinder is removed by removing the
torx screw through the access hole in the door.
Once the screw is removed, the lock cylinder can
be pushed out of the handle assembly.
The handle is removed by loosening the hex nut
holding the handle to the latch mechanism.
The handle is then removed by pulling it out and
down to release it from the latch. The handle is
turned down to the left to release it from the door
latch assembly.

Each backrest can be adjusted individually
up to 20 degrees. the backrest adjustment
option consists of the following:
• Left/Right adjusting motors with gear
drive and seat back hooks - located
behind the seat backs on the shock
towers. The rear seat backs lock into
the “D” shaped hooks on the backrest
adjustment linkage.
• Left/Right adjusting switches - located
in the interior light housing in the head-
liner panel.
• Left/Right adjusting switches - located
in the rear on the left and right sides of

Cargo Area
The sliding load floor is available as an option on the
X5. It is mounted through two sliding bushing on two
steel rails
The load floor is held in position by the
locking bowden cable mechanism that
latches when closed to prevent the
floor for sliding while the vehicle is
moving. The load floor incorporates a
shear point that will cause the floor to
collapse upward in a rear collision.

Tailgate
The tailgate on the X5 is two sections that
open up and down. The upper section has a
fixed bonded rear glass that incorporates the
rear window wiper and motor assembly. Two
gas strut pistons are used on the upper sec-
tion for opening. An electric actuator is incor-
porated in the upper section with the micro
switch for operation located between the two
license plate lights. The actuator locks into
the lower tailgate section when closed.
A micro-switch positioned in the center console switch
panel is used to open the tail gate from inside the
vehicle.
Operation of the upper tail gate is con-
trolled from the GM which locks the
operation of the gate when the vehicle
speed is over 5 MPH. A dealer installed
class three trailer hitch is available as an
option with a towing capacity of 6000
pounds.

Air Supply System (LVA)
The air supply system is identified as the LVA in the diagnosis program and in the repair
manual. It is mounted in the spare tire well compartment. The components are housed in
a sound deadening carrier, through rubber bushings, to prevent operating noises from
being transmitted through the vehicle’s interior.
With the exception of the compressor relay, individual replacement parts for the air supply
system are not available. If diagnosis determines a defect in any of the other air system
components, complete replacement is necessary.
The air supply system consists of the following components:
• Compressor assembly with;
- Piston compressor
- Electric motor
- Air dryer (desiccator)
- Pressure relief solenoid valve
- Pressure maintenance valve
- Check valves
• Compressor Relay (Replaceable)
• Solenoid Valve Block (2 - two way valves)

Air Supply System (LVA) Operation
The single stage piston compressor produces a maximum pressure of 13.5 Bar. The com-
pressor is maintenance free - provided it is used in a dust free environment. This includes
the compressor’s intake air filter.
The compressor is driven by a DC motor that is controlled by the compressor relay through
the control module.
When the compressor is activated, the pressure builds up to a working pressure of 11.4
Bar (+0.8/-1.5 Bar). This is controlled through the pressure maintenance valve. The air
under pressure is fed through the dryer and check valve to the solenoid valve block for the
air springs.
There is one solenoid valve in the valve block for each air strut. This allows the system to
compensate for uneven loads in the vehicle and maintain the vehicles ride height at all
times.
Pressure is drained through the left or right solenoid valve (energized open) the pressure
relief solenoid valve, restricter, check valve and dryer back to the inlet side of the compres-
sor pump.
