Driving In Cold Weather - Volvo 9700 US/CAN 2016 Driver's Handbook Manual

Driving in cold weather

Before driving in cold weather conditions
with ambient temperature of 41 °F (5 °C) or
below, pay attention to the following points:
1 The cooling system must be protected
against freezing.
2 The washer fluid reservoir must be filled
with winter liquid.
3 Batteries must be in good conditions. In
low temperatures, the batteries capacity to
deliver current drops, i. e. when starting
the engine. Make sure that the poles of
the batteries are thoroughly clean, with
the cable terminals properly tightened and
covered with grease, and that there is the
correct amount of electrolyte in every cell.
4 Engine oil, as well as transmission and rear
axle oil, must have the correct viscosity.
5 Fill up the tanks with winter fuel. This
reduces the risk of wax settling in the
fuel system. If this has already happened,
change the fuel filters and fill up the tanks
with winter fuel. Keep the tanks as full as
possible.
6 The compressed air system is particularly
sensitive to low temperatures. Excessive
condensation in the primary tank indicates
that the air drier is not working properly.
Drain the tank and change the desiccator
cartridge in the air drier. If none of these
measures help, use an external heating
source to defrost the system.
