Driving Through Deep Standing
Water
If you drive too quickly through deep puddles

standing water, water can come in through
engine's air intake and badly damage your
engine. If you can't avoid deep puddles or
standing water, drive through them very slowly.
Engine Block Heater (Option)
In very cold weather, O°F (-18 "C) or colder, the engine
block heater can help. You'll get easier starting and
better fuel economy during engine warm-up.
To use the block heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt outlet.

CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a
fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt outlet. If the cord won't reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.

How long should you keep the block heater plugged in?
The answer depends on the weather, the kind of oil you
have, and some other things. Instead of trying to list
everything here, we ask that you contact a Buick dealer in
the area where you'll be parking your vehicle. The dealer
can give you the best advice for that particular area.
