Vehicle underbody check (Every 10 000 miles (15 000 km) or 12 months)
Note: Steam-cleaning is available at many garages for the purpose of removing any accumulation of oily grime from beneath a vehicle.
1 Raise the vehicle sufficiently enough to allow a complete uninterrupted view of its underside.
2 Wash the vehicle underbody down as thoroughly as possible.
3 Carefully check all underbody paintwork, looking closely for chips or scratches. Check with particular care vulnerable areas such as the front spoiler and around the wheel arches.
Any damage to the paintwork must be rectified to prevent further corrosion.
4 If a chip or light scratch is found that is recent and still free from rust, it can be touched-up using the appropriate paint. More serious damage or rusted stone chips can be repaired as described in Chapter 11. If damage or corrosion is so severe that a panel must be renewed, seek professional advice as soon as possible.
5 The wax-based underbody protective coating should now be inspected to ensure that it is unbroken and any damage to the coating repaired using undershield. If any body panels are disturbed for repair or renewed, do not forget to replace the coating and to inject wax into door panels, sills, box sections etc. so as to maintain the level of protection provided by the manufacturer.
6 Check carefully that all wheel arch liners and underwing shields are in place and securely fastened.
7 Finally, check that all door and ventilator opening drain holes and pipes are completely clear so that water is allowed to drain.
