INFORMATION Propeller shaft Front
and RearNLGI - 2 Multi-purpose Lithium based GREASE
Lubrication nipples
(hubs, ball joints
etc.)
Seat slides
Door lock striker
Brake and clutch
reservoirsBrake fluids having a minimum boiling point of 260°C (500°F) and complying with
FMVSS 116 DOT4
Engine coolant Use an ethylene glycol based anti-freeze (containing no methanol)
V8i, Tdi, Mpi with non-phosphate corrosion inhibitors suitable for use in aluminium engines to ensure
the protection of the cooling system against frost and corrosion in all seasons. Use one
part anti-freeze to one part water for protection down to -36°C (-33°F).
IMPORTANT: Coolant solution must not fall below proportions one part
anti-freeze to three parts water, i.e. minimum 25% anti-freeze in coolant otherwise
damage to engine is liable to occur. Or a maximum of 60%.
Battery lugs, Petroleum jelly.

LUBRICATION PRACTICE
Use a high quality oil of the correct viscosity range and service classification in the engine during maintenance and
when topping up. The use of oil not to the correct specification can lead to high oil and fuel consumption and
ultimately to damaged components.
Oil to the correct specification contains additives which disperse the corrosive acids formed by combustion and
prevent the formation of sludge which can block the oilways. Additional oil additives should not be used. Always
adhere to the recommended servicing intervals.
WARNING: Many liquids and other substances used in motor vehicles are poisonous. They must
not be consumed and must be kept away from open wounds. These substances, among others,
include anti-freeze windscreen washer additives, lubricants and various adhesives.
