Engine lubricating system
During the winter multigrade oil SAE 10 W-30 or engine oil with a vis-
cosity of SAE 10 W should be used for the engine lubricating system.
These oils reach the lubricating points in the engine more easily at low
temperatures and also facilitate cold starting. If you drive mainly short
distances during the winter, the engine oil should be changed more often
than usual, for example after every 2 500 km (1 500 miles). See page 36.
Electrical system
The electrical system in the vehicle is subjected to greater stresses during
the
winter than during the warm summer months. The lighting and the
starter
motor are used more and since the capacity of the battery is also
considerably lower with low air temperatures, the state of charge must
be checked more often. If the specific gravity of the electrolyte is ex-
cessively low there is risk of frost damage to the battery.
Brake system
During the winter the brakes are subjected to splash and condensation
water to a greater extent than during the summer and the result of this
can be that the handbrake cable may freeze up if the handbrake is left
on.
When you park the car, do not apply the handbrake but engage
bottom gear or reverse.
Windscreen washer
In the same way as anti-freeze is added to the cooling system during the
winter to prevent frost damage, anti-freeze should also be added to the
windscreen washer water container. This is particularly important during
the
wintertime when the car is often exposed to dirt and water which
can rapidly freeze on the windscreen and necessitate the frequent use
of the windscreen washers and wipers. Your Volvo dealer can supply
you with a suitable anti-freeze for this purpose.
Anti-freeze for door locks
A frozen door lock is one of the most irritating things that can happen
to a car-owner. Many valuable minutes early in the morning can be
wasted warming up keys and melting ice in locks. Remember this in good
time and lubricate the lock with some anti-freeze preparation.
