Driving during cold weather

Check the 12V starter battery, including terminals and
cables. During extremely cold weather, the 12V starter
battery will not be as strong and its power level may drop.
Before driving the vehicle, check to see if the headlights
are as bright as normal. Charge or replace the 12V starter
battery if necessary. During extreme cold weather, it is
possible that a very low 12V starter battery could freeze.
Check the antifreeze.
If there is not enough coolant because of a leak, add high-
quality ethylene glycol antifreeze and water. Use Dia
Queen Super Long Life Coolant Premium or an equiva-
lent. The recommended blend is about 50 % water and 50
% anti-freeze. Use a higher concentration (not over 60 %)
when the outside temperature is -31 °F (-35 °C) or lower.
When the electric motor unit is working very hard (for
example, during mountain driving and/or when the out-
side temperature is high), use a 50 % concentration. This
blend will provide adequate protection from corrosion and
boiling.
WARNING
!
The 12V starter battery gives off explosive hydrogen
gas. Any spark or flame can cause the 12V starter
battery to explode, which could cause serious injury
or death.
Always wear protective clothes and a face mask
when working with your 12V starter battery, or let a
skilled mechanic do it.
WARNING
!
Never open the coolant reservoir cap while it is hot.
You could be seriously burned.
