If the air conditioning does not work well

Usually, use the air conditioning with the

mentfriendly cooling).  
In this mode the gasoline engine starts  
and stops automatically and good fuel  
economy driving is achieved.  
With the “MAX” button on, the gasoline  
engine is frequently used.  
The air conditioning may not turn on with  
the selector lever in “N” position because  
the gasoline engine cannot start.  
To use the air conditioning in economi-  
cal and environment−friendly way, we  
recommend the following setting:  
If the “A/C” button indicator flashes, there  
is a problem in the air conditioning system  
and the air conditioning automatically  
shuts off. If this happens, take your ve-  
hicle to your Toyota dealer for service.  
1. Lower the setting temperature if you  
feel a little hot with the “A/C” button  
on.  
2. If you feel still hot with the “A/C” but-  
ton on, push the “MAX” button also.  
After the compartment cools, turn off  
the “MAX” mode only.
