Cold Weather Tips; General Information - Saab 1992 900 Owner's Manual

Starting and driving 51
Apply the handbrake and put the gear
lever in neutral (manual transmission)
or select P or N (automatic transmis ­
sion). Cars with automatic transmission
can only be started when the gear se­
lector lever is in P or N.
2 Depress the clutch pedal (manual trans ­
mission).
3 Turn the key to the start position and let
it spring back as soon as the engine is
started. Allow the engine to idle for
about 10 seconds before touching the
accelerator. Avoid full throttle accelera ­
tion until the engine has run for 2-3 min­
utes.
NOTE!
16 valve engines have hydraulic valve lift ­
ers which require no maintenance. The
clearances are pre-set when the engine
is assembled and no adjustments are
necessary. Some valve lifter noh3,e may
be heard for a few seconds after the en ­
gine has been started, and this should be
considered normal. The valve noise will
disappear once the engine oil has
reached normal working pressure.
Cold weather tips
On cars with the manual transmission, re­
lease the clutch pedal slowly after starting
to avoid stalling. For cars with the automatic
transmission, allow the engine idle to sta­
bilize for a few seconds before selecting a
forward or reverse gear.
If the engine should stall after a cold
weather start and fail to restart, depress the
accelerator fully while running the starter
motor to ventilate the engine and prevent it
from flooding. Avoid repeated short crank­
ing cycles in quick succession as this can
have a negative eHect on starting ability.
Opening the throttle slightly as the engine
begins to run may help ventilate the engine
and keep it running. A winter grade of en ­
gine oil (5W-30) will improve starting in ex ­
treme cold weather.
CAUTION!
Turbocharged
engin~s:
STARTING-Do not rev the engine imme;
diately after starting or permanent dam ­
age to the turbocharger will result.
STOPPING-Let the engine idle 20-30
seconds before switching it oft after driv­
ing to
allo~
time for the turbocharger to
coast down from high rpm before oil pres­
sure at the bearing is depleted. For the
same reason, do not rev the engine im ­
mediately before switching if
oH.
Perma­
nent turbocharger damage will result.
General information, turbochargers
1 Starting and driving
• Never accelerate at full throttle before the
reading on the temperature gauge is nor ­
mat (N).
• If the needle on the pressure gauge re­
peatedly enters the red zone, a loss of
engine power may be experienced owing
to the safety cut-out system limiting the
charging pressure. Take the car to an
authorized Saab dealer without delay.
Under certain atmospheric conditions,
the needle may briefly enter the broken
red zone, but this is normal and does not
indicate a malfunction.
• The engine is also equipped with a safety
cut-out to prevent the engine exceeding
approx 6000 rpm.
2 Stopping the engine
• Do not rev the engine immediately
be~ore
switching it oH but always switch it oH
when it is idling. This is to ensure that the
turbo compressor is not run unnecessar­
ily without adequate oil pressure.
3 Automatic Performance Control (APC)
The APC system is designed to give opti ­
mum engine performance when 93 octane
fuel (AON) is being used. When fuel of this
octane rating is used, the engine will deliver
maximum power. However, one of the ad ­
vantages of the APC system is that the en ­
gine can be run on cheaper grades of low­
