B740D01A-AAT Operation Tips
o If the interior of the car is hot when you first
get in, open the windows for a few minutes to expel the hot air.
o When you are using the air conditioning sys- tem, keep all windows closed to keep hot airout.
o When moving slowly, as in heavy traffic, shift to a lower gear. This increases engine speed,which in turn increases the speed of the airconditioning compressor.
o On steep grades, turn the air conditioner off to avoid the possibility of the engine over-heating.
o During winter months or in periods when the air conditioner is not used regularly, run theair conditioner once every month for a fewminutes. This will help circulate the lubricantsand keep your system in peak operatingcondition.
