Routine servicing of your vehicle should be carried out in accordance with the original manufacturer’s service manual. You will find any radio/key/security codes which are needed in the manufacturer’s handbook.
If your vehicle is fitted with a lift, steps, rear heater or rear air conditioning these also need routine servicing. This should not be ignored as it could lead to failure and potential injury to the user, and could also invalidate your warranty (see our Owner’s Manual for further details). Please refer to the separate documentation from the relevant supplier(s) to find out the recommended inspection schedule and how to find your nearest service engineer
