Preparation For Test

Special Tools:

Hydraulic Test Line P/N 129 806 34 83:

Conventional Tools:
Graduated beaker (0.5 liter, 10 ml graduations).

WARNING:
Risk of personal injury (pinching/crushing) while working (loosening or removal) of pre-tensioned components. Use only approved special tools, tensioning devices, stops etc. in order to prevent serious injury. Visually inspect special tools for proper condition/function and possible damage prior to use. When using spring compressor tools, it is important that the spindle is not used in a damaged condition, that the threads are clean and proper. The spring plates are to be straight and not bent in any fashion. Note the assembly location of each spring plate and that the tightening nut threads are compatible and clean to the spindle. Do not use an impact tool to loosen or tighten the spring compressor tool nut. Wear safety gloves.

Risk of personal injury (pinching/crushing) while working on partially opened retractable hardtop. The rest mode is the interruption of the opening or closing sequence of the retractable hardtop, if the switch (S84) is released while being used to open or close the hardtop.

The rest mode holds the partially opened or closed retractable hardtop in this position for 7 seconds, thereafter the system is de-pressurized and depending on the position, the hardtop will come to rest upon itself. The danger of personal injury (pinching/crushing) exists if the work that is being carried out without first using the special tools to safely support the hardtop. Please review and use the special tools as mentioned in [ ] 33

Risk of personal injury (pinching/crushing) and in extreme cases loss of limbs or fingers, while working with components that are actuated either by hand, electrically via motors, hydraulically or pneumatically via connecting mechanical components, by reaching into moving components or mechanical units.

It is important that limbs, fingers and body parts be kept away from the operating areas of the moving components, especially if the components are actuated via the HHT or directly via circuit 30. Ensure that the test cables are of proper length, to prevent entanglement.

Keep clear of the retractable hardtop frame and linkage, upper part of the windshield and trunk lid during any retractable hardtop operation.

Lastly, it is important to wear safety gloves when performing the tests.

CAUTION:
Before begining the test, check the oil level in the hydraulic unit reservoir and top up if needed.

NOTE:
In order to make accurate visual inspection for oil loss from the hydraulic system, the trim panels covering the hydraulic components must be removed.

The front latch can be locked or unlocked using the special tool provided with the vehicle for manual hardtop operation. The trunk can be unlocked using pull cables (refer to Owners Manual).

The hydraulic circuits and components for each operation of the hardtop can be tested separately.
