Starting The Engine; Catalytic Converters; Hydraulic Tappets - Volvo 850 Manual

Starting the engine

Starting the engine:
Apply the parking brake
Move the gear lever to P (automatic
transmission)
Press the clutch pedal (manual gearbox)
Do not touch the accelerator pedal
Turn the ignition key to the starting
position. Let the starter motor operate
until the engine fires, but never for
more than 5 seconds at a time.
Note! Turbo for 10 seconds.
For better cold-starting performance, turn the
key to position II and wait for one second so
that fuel pressure can be built up. Then turn the
key to the start position.
For cold starts at altitudes in excess of approxi-
mately 1800 m, you can assist the engine by
pressing the accelerator pedal halfway to the
floor at the same time as the key is turned to
the start position. Release the accelerator pedal
slowly once the engine starts up.
Never race the engine immediately after
a cold start.
If the engine does not start or if it misfires,
contact your nearest Volvo dealer.
Cars with catalytic converters may never
be tow-started. Failure to observe this
instruction may result in impairment of
the catalytic converter.
CAUTION -

CATALYTIC CONVERTERS

The catalytic converter normally has an
operating temperature of several hundred
degrees Centigrade. Do not park the car
on inflammable material such as high grass
which may be ignited by the catalytic
converter.

Hydraulic tappets

This engine features hydraulic tappets which
means that valve clearance is adjusted automa-
tically. It is possible that the hydraulic valve
tappets produce a ticking sound for the first
few seconds after an engine is started, while
the oil pressure is being built up. If the car has
not been used for a long period of time, this
ticking sound may be heard for up to 15 min-
utes, but this is entirely normal.
NB ! Do not exceed 3000 rpm until the ticking
sound disappears.
WARNING FOR CARBON MONOXIDE
Always open garage doors completely before starting the engine inside a garage.
Exhaust gases contain carbon monoxide, which is invisible and odourless but lethal.
Warm up the engine as soon as
possible
After the engine has been started, it is important
to try and reach normal operating temperature as
soon as possible.
Drive off immediately under moderate accelera-
tion; do not allow the engine to operate unne-
cessarily at idling speed.
Experience shows that engines in cars which
have been driven for short distances with many
stops are worn out exceptionally quickly. The
reason for this is that these engines never have
the opportunity to reach normal operating tem-
perature.
