If you judge it to be safe, drive carefully to the nearest service station for repairs. Otherwise, have your vehicle towed because driving it could be dangerous. ● Pressing the brake pedal with the engine stopped and/or a low brake fluid level may increase your stopping distance and braking will require greater pedal effort as well as pedal travel.

Refer to "Variable voltage control system" in the "Maintenance and do-it-yourself" section later in this manual. ● Do not continue driving if the generator belt is loose, broken or missing. CAUTION Running the engine with the engine oil pressure warning light on could cause serious damage to the engine almost immediately. Such damage is not covered by warranty. Turn off the engine as soon as it is safe to do so. 2-14 Instruments and controls
