Winter Driving
Here are some tips for winter driving:
Have your Buick in good shape for winter. Be sure
your engine coolant mix is co-rrect.
Snow tires. can help in loose snow, but they may give
you less traction
on
ice than regular tires. If you do
not expect to be driving
in
deep snow, but may have
to travel over ice, you may not want to switch to
snow tires at all.
You may want to put winter emergency supplies in
your vehicle.
