Leave the M42 at junction 6 and take the A45 Coventry Road towards the city centre and the airport - it's the first exit if you're travelling northbound, and the third exit if you're travelling southbound.
Go through two sets of traffic lights, passing the Holiday Inn on your right. At the third set of traffic lights, get into the right hand lane. You'll see a signpost for off-site airport parking. Turn right onto Sheaf Lane towards Garretts Green and Marston Green.
Follow this road until you reach a roundabout; take the third exit, following the sign for off-site airport parking site A. After half a mile, turn left into Mackadown Lane. Airparks is on the left, just before the railway bridge.
