Economical Driving; Driving In Winter Weather - Saab 9001994 Owner's Manual

58 Starting and driving
To disengage the cruise control
The cruise control system disengages au-
tomatically:
• when either the brake pedal or clutch
pedal is depressed
• when the switch is moved to the OFF or
TI P position
• when the engine is switched off.
WARNING!
Do not use the cruise control system on
winding, wet or slippery roads or in
dense traffic.
2 Keep the system switched off when not
in use to prevent inadvertent engage-
ment, e.g. when signalling a turn.
3 If the gear lever is unintentionally
moved to neutral while driving with the
cruise control engaged, depress the
brake (or clutch) pedal momentarily or
move the cruise control switch to OFF.
Failure to do so will cause the engine to
overrev.
4 Always switch the cruise control switch
to the OFF position before turning the
engine off.
Failure to follow the warning points above
could lead to inadvertent activation of the
cruise control system with the potential for
a vehicle accident causing personal injury.
Economical driving
For maximum economy, the Saab 900, like
any other car, needs to be driven moder-
ately. Avoid unnecessary full throttle accel-
eration and high engine speeds wherever
possible.
Driving in congested areas and driving with
a roof rack or trailer, all contribute to high
fuel consumption . Excessive idling and
"warming up" the engine also wastes gas.
Use the air conditioner only when neces-
sary. Winter temperatures and use of win-
ter tires are other factors that may increase
fuel consumption.
Maintaining your car according to the rec-
ommended maintenance schedule will help
you get maximum fuel economy. Be sure
the engine is tuned to specification, the bat-
tery is fully charged and wheel alignment
and tire pressures are correct.
Selecting shift points to maintain engine
speeds within the economy range shown
on the tachometer face will also aid in ob-
taining maximum fuel economy. See also
shift light use on page 53.
Winter driving
Before driving off in cold weather, check
that the windshield and headlight wiper
blades have not become frozen to the
glass. Brush away any snow from the air
intake for the heating system and, in ex-
tremely cold weather, apply suitable lubri-
cant (molybdenum disulfide) to the door
lock to prevent its freezing. If the lock has
frozen, take care not to break the key when
trying to unlock it. Heat the key first or ap-
ply some deicing agent to it.
It is particularly important when the roads
are slippery that the brakes and tires are in
good condition. For driving in snow and ice,
we recommend that special winter tires,
available through your dealer, be fitted.
Winter tires provide the best grip on icy
roads, especially if fitted with studs (check
your state/provincial law).
If winter tires are to be used, the same type
of tire must be fitted to all four wheels. Your
local Saab dealer will be pleased to advise
you of suitable tires.
Ordinary snow chains (avoid clamp-on
types) can be used on both front and rear
wheels . Drive carefully since chains may
scrape against the body on large 'bumps or
sharp turns.
