4 Place the gear selector lever in neutral/park (position N or P on cars with automatic
transmission).
5 Without touching the accelerator pedal turn the ignition key to starting position. Release the key
as soon as the engine starts.
Avoid repeated short attempts to start (fuel is injected every time the starter is engaged when engine is
cold). Allow the starter to operate for a longer time (but not more than 15 - 20 seconds).
Do not race a cold engine immediately after starting. Oil flow may not reach some lubricating
points fast enough to prevent engine damage.
CAUTION: (740 GLE 16 valve) The hydraulic valve lifters can cause a ticking noise directly after
start, especially if the car has not been driven for several weeks. While the valves are "ticking", keep
engine speed under 3000 r.p.m.
WARNING!
Always open the garage doors fully before starting the engine inside a garage to ensure adequate
ventilation. The exhaust gases contain carbon monoxide, which is invisible and odorless but very
poisonous.
Engine warm-up - initial driving procedure
Experience shows that engines in vehicles driven short distances are subject to abnormally-rapid wear
because the engine never reaches normal operating temperature, It is therefore beneficial to reach normal
operating temperature as soon as possible. This is best achieved by driving with a light foot on the
accelerator pedal for a few minutes after starting, rather than prolonged idling.
Turbo caution
Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast
enough to prevent engine damage. Before switching off the engine, let it operate at idle for a short time
to allow the spinning of the turbo-compressor's turbine vanes to slow. After hard driving, this idle time
should last a couple of minutes, during which the vanes will slow and the compressor will cool down
while still receiving lubrication. If the turbine vanes are spinning at high speeds when the engine is
switched off, there is a great risk of heat damage and/or turbine seizure due to lack of lubrication.
Do not race the engine just prior to switching off!
