Driver Controls and Instruments Transmission Oil Temperature Gauge 1 2 With an Allison automatic transmission, the transmission oil temperature gauge reading should not exceed 250°F (121°C) during normal operation. A warning light will activate to alert the driver. CAUTION 3 A sudden increase in oil temperature that is not caused by a load increase may indicate mechanical failure. Bring the vehicle to a safe stop and investi- gate the cause to prevent further damage. Do not operate the engine until the cause has been deter- mined and corrected. f830809 1. Temperature Control Lever 2. Defrost Position 3.

Function Control Lever Heater and Ventilation System The Floor/Panel position directs air through the windshield, floor, side panel, and center panel (unheated) vents. Fig. 3.22, Climate Control Panel A dash-mounted climate control panel ( Fig. 3.22 ) allows you to control all of the heating, defrosting, and ventilat- ing functions. The Defrost position directs air through the wind- shield and side panel vents. The center panel vents, if left open, will provide unheated air. Air flow from the side panel vents, when directed to- ward the door windows, will help avoid window fogging. A temperature control lever is used to select the desired temperature.

Slide the lever to the left for cool air, or to the right for warm air. A function control lever controls the direction of warm or cool air. The Panel position directs unheated air through the center panel vents only. 3.17
