3. Operating Instructions
The Thule Step Single Step V10 is a manual step designed for ease of use.
To Extend the Step:
- Locate the release mechanism, typically a handle or lever, on the side or underside of the step unit.
- Gently pull or push the release mechanism to disengage the lock.
- Manually pull the step outwards until it is fully extended and locks into place. You should hear an audible click, indicating it is secure.
- Before stepping on it, verify that the step is stable and fully locked.
To Retract the Step:
- Ensure no one is standing on the step.
- Locate the release mechanism.
- Gently pull or push the release mechanism to disengage the lock.
- Manually push the step inwards until it is fully retracted and secured against the vehicle. Ensure it is flush and locked to prevent accidental deployment during travel.
4. Maintenance
Regular maintenance ensures the safe and reliable operation of your Thule Step.
- Cleaning: Clean the step regularly with mild soap and water. Avoid abrasive cleaners or solvents that could damage the aluminium finish. Rinse thoroughly and dry.
- Lubrication: Periodically apply a silicone-based lubricant to the pivot points and moving parts to ensure smooth operation. Avoid petroleum-based lubricants as they can attract dirt.
- Inspection: Before each use, visually inspect the step for any signs of damage, corrosion, loose fasteners, or excessive wear on the moving parts. Pay close attention to the mounting brackets and the step surface.
- Fasteners: Check all mounting bolts and screws periodically and tighten if necessary. Do not overtighten.
5. Troubleshooting
If you encounter issues with your Thule Step, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Step is difficult to extend or retract. | Lack of lubrication, dirt/debris in mechanism, minor misalignment. | Clean the mechanism and apply silicone lubricant to moving parts. Check for obstructions. |
| Step does not lock securely. | Locking mechanism obstructed or worn, bent components. | Inspect the locking mechanism for debris or damage. Clean or replace if necessary. Do not use if not securely locked. |
| Unusual noises during operation. | Dry pivot points, loose fasteners, foreign object. | Lubricate all moving parts. Check and tighten all fasteners. Inspect for any foreign objects. |
| Step feels unstable. | Loose mounting bolts, damaged frame, incorrect installation. | Immediately cease use. Inspect all mounting bolts and tighten. Check for structural damage. Consult a professional for inspection and repair. |
If problems persist after attempting these solutions, contact Thule customer support or a qualified service technician.
