Awning (Kemerton XL, 2018 Model Year)
AwningFrequently Asked Questions
Q: How do I set up the Thule Omnistor awning?
Fit the crank handle to the right length and slot it into the bayonet socket, then turn it anticlockwise - keeping the handle down - to unroll the awning; it won't move for the first couple of turns. Once you've unrolled about a metre, put the support legs out before continuing. Slide the legs from the front profile, adjust them to height, and fasten them (rolling the fabric up slightly helps tension it, but don't extend the legs so high the fabric jams against the arms).
Fit the tension rafter too on larger models. If it's raining, drop one side so water runs off, and use the hold-down kit in gusty conditions - the front profile locks automatically once it's rolled back up.

Reversing Camera / Camera SystemFrequently Asked Questions
Q: How does the reversing camera work?
The camera links up with the Garmin satnav unit on the dashboard over Bluetooth the moment you select reverse, with the rear view showing on the satnav screen itself. It doesn't have a separate always-on setting - reverse gear is the only thing that switches it on.

N/A | The power-operated rear step is still out when the ignition gets switched on. | — | A buzzer behind the dashboard sounds the moment the ignition's switched on, and keeps going until the step's been fully retracted. | DIY Safe |
N/A | Dirt and frost preventing the electric step from operating properly | Accumulation of dirt or frost in moving parts | Clean or defrost the moving parts. | DIY Safe |
Frequently Asked Questions
Q: How does the electric rear step work?
A button by the entry door controls it - press once to send it out, press again to bring it back in. Starting the engine retracts it automatically, with a short buzzer as warning; if something's blocking it or it fails to retract, that buzzer carries on sounding until the fault's cleared. It's usually tied to the remote locking too - unlock the doors and it comes out, lock them and it goes back in - though your dealer can disable that link if you prefer.

N/A | No 230V output from the PSU | The lead linking the site supply to the vehicle isn't plugged in | Check the lead is connected correctly at both ends. | DIY Safe |
N/A | No 230V output from the PSU | RCD switched off | Reset the RCD. | DIY Safe |
N/A | No 230V output from the PSU | RCD not operating | Check the supply polarity; if the RCD keeps failing, contact your dealer, as there's likely an equipment or wiring fault. | DIY Check / Tech Fallback |
N/A | No 230V output from the PSU | MCB switched off | Reset the MCB by switching it off (down) then back on (up); if it keeps tripping, contact your dealer, as there's likely an equipment or wiring fault. | DIY Check / Tech Fallback |
N/A | No 230V output from the PSU | No or deficient supply from the site | Contact the site warden for assistance. | Professional Intervention Required |
N/A | Reverse polarity warning light is illuminated on the PSU | — | This light is designed to catch a reversed/crossed live and neutral supply on UK-wired sites - if it comes on, suspect a fault with the site's own supply, or its connecting cable (outside the UK it can light up with no actual fault present, so check with the site warden). It can also light up quite normally when running from certain generators, since some centre-tap their earth connection rather than earthing the neutral directly, leaving both conductors roughly 110V above earth - usually still safe to keep using in that case, but check the generator's own handbook. | DIY Check / Tech Fallback |
N/A | Control Panel has no display | — | The screen's backlight might have simply turned itself off - tap select to wake it again. If that's not it, work through the batteries and fuses, confirm both the shutdown switch and the charger switch on the PSU are set to on, and that mains is plugged in. Also check the lead running between the PSU and the back of the panel. Still nothing? Get in touch with your dealer. | DIY Check / Tech Fallback |
N/A | 12V power turns off unexpectedly | — | Usually the battery-protect feature has stepped in to protect the vehicle and/or leisure battery, or the engine's been started, in which case equipment is disconnected automatically to meet EMC requirements while driving. | DIY Safe |
N/A | Control panel is locked or behaves erratically | — | Check you're following the control panel's own handling instructions. If the panel's software has crashed, reboot it by turning off the PSU's isolator switch, waiting 30 seconds, then switching it back on. | DIY Safe |
N/A | No 12 volt output from the PSU | No 230V supply | Check the 230V supply first: the hook-up lead is plugged in at both ends, the RCD and MCB are both switched on (reset either one if it has tripped), and the site's own supply is actually live. | DIY Safe |
N/A | No 12 volt output from the PSU | Charger not switched on | Turn the charger switch on - it will illuminate when active. | DIY Safe |

Q: Does the refrigerator need a winter cover?
If you're using it when the outside temperature drops below 10°C, yes - fit the winter cover (supplied) to stop the cold air affecting performance. Take it off again once temperatures climb back above 10°C, or the fridge won't cool as well.

Q: What do I do if my Auto-Sleeper is stolen?
A Teletrac Trackstar TM470 tracker, hidden somewhere on the vehicle, keeps watch using Thatcham category 6-approved GPS technology - move the vehicle without the ignition on, or tamper with the battery, and it fires an alert straight to your phone. From there it's the usual process: report it to the police for a crime reference number, then call 0345 561 9990 to reach Trackstar's own Control Centre in the UK, or +44 1234 759502 if you're reporting a theft from Europe.
It runs on an annual subscription - call 0345 604 5433 or go to www.teletracnavman.co.uk/trackstar to activate it - and Customer Support on that same number needs telling if you sell up or change your mobile number.

Frequently Asked Questions
Q: How do I winterise the water system before storing the vehicle for winter?
Open the drain valve next to the water heater, and leave the fresh and waste water tank drain taps open too. Open every internal tap, then run the pump until it stops delivering anything. Go for a short spin with those drain taps still open - it helps shift the last of the water out of the tanks and pipework. Pull the sink plugs so the system can breathe, give the waste tank a thorough flush to shift any debris, finish with a flush of mild disinfectant, and leave the drain tap open.

N/A | Concertina blind or flyscreen has become stiff and difficult to operate | The mechanism has dried out or picked up dust/grit over time - these units need only light, occasional lubrication. | Apply a light lubricant to the mechanism. Avoid cleaning solvents or aerosols on the blind material itself, as it's a paper-type fabric that these can damage. If the problem persists, contact your Auto-Sleepers dealer. | DIY Check / Tech Fallback |
