On i-25 going north the instrument panel beeped then showed all red indicator lights on. beeping was continual every 10 seconds. all gages went to zero: speedometer rpm, gas, temp etc... also r/left turn indicators did not function; nor the wiper blades [front or rear]. vehicle could be driven [cautiously] as head & rear lights and brake lights functioned. i do not know if the air bag release mechanism was affected. we had 250 miles to go, half in daylight. very difficult to merge from i25 to i40 during rush hour traffic without turn indicators. *js
