Poor fuel economy?

Hi,

That's a tough question to answer because there are so many variables that can change MPG. For example, if you drive in an area with a lot of hills, that can lower it. If you are running the AC, that can lower it, there are other things as well.

The one thing that can cause lower MPG is a dirty air filter. Have you checked to make sure it is clean?

Let me know.

Hi,

Do you mean the battery isn't being charged when you are at idle? If that is the case, here is a link that explains how to test the alternator. It is very easy. All you need is a voltmeter or a multimeter.

Let me know what you find. Interestingly, I love hot weather, but that is a little over the top for me. Ugh!!! 110F? You must feel like you are in an oven.

Let's see if the alternator is working properly. If it isn't, that can cause all kinds of different things to be off.

Let me know.

Hi,

You are correct. There isn't a traditional alternator. I'm still getting used to these vehicles. LOL

As far as the light is concerned, you are correct. It shouldn't stay on. Because of the hazards of working on a high voltage circuit, I would suggest having it checked by a certified shop. I can help with directions, but not being there, I don't want to misdirect you. I hope you understand.

Let me know.

Joe

You are very welcome. Said, electric vehicles produce enough voltage to seriously hurt or kill a person. Please be careful.

Take care,

Joe

Hello SAID84, I just wanted to join in the conversation. The MPG will vary depending on your driving habits as stated earlier on. I also noticed you're driving in sport mode. You will get less MPG when driving in sport since the lower gears are held much longer, The EV mode on your vehicle is only active on low speeds. Any sudden accelerations or highway speeds will make the gas engine run.

Depending on the driving conditions one or both sources are used to power the vehicle.
The following demonstrates how the ES300h operates in various driving
modes.
During light acceleration at low speeds, the vehicle is powered by the electric motor.
The gasoline engine is shut off.
During normal driving, the vehicle is powered mainly by the gasoline engine.
The gasoline engine also powers the generator to recharge the battery pack and to
drive the motor.
During full acceleration, such as climbing a hill, both the gasoline engine and the
electric motor power the vehicle.
During deceleration, such as when braking, the vehicle regenerates kinetic energy
from the front wheels to produce electricity that recharges the battery pack. While the vehicle is stopped, the gasoline engine and electric motor are off, however
the vehicle remains on and operational.

In conclusion your MPG's appear normal and if there was an issue your check engine light and hybrid malfunction lights would come on. Just make sure your tires are properly inflated with good tread. Alignment is straight. And keep up with your maintenance.
