DRIVING AND ALCOHOL

Drunken driving is one of the most frequent causes of
accidents.

Your driving ability can be seriously impaired with blood
alcohol levels far below the legal minimum. If you are
drinking, don’t drive. Ride with a designated non­drinking driver, call a cab, a friend, or use public trans­portation.

WARNING!

Driving after drinking can lead to an accident.
Your perceptions are less sharp, your reflexes are
slower, and your judgment is impaired when you
have been drinking. Never drink and then drive.

2. Engine Coolant Temperature

This gauge shows the engine coolant temperature. The
gauge pointer will likely show higher temperatures when

engine. DO NOT operate the vehicle until the cause is
corrected.

A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, refer to “Dealer Service” in
“Servicing And Maintenance”. Follow the warnings
under the “Cooling System Pressure Cap” paragraph.
