    Unhappy Getting terrible Km/l with my Prius - Help.

    Higuys. I am new to the forum. I just bought a prius 3 days a ago. Its a 2007 NWS-20. The problem is i am getting 10 or 11 km/l. I have tried everything i could find on the net from less pressure on pedal and coasting to lot of regenerative braking and inflating the tires ti 34 Psi. I think its the 12 V battery issue. Can somebody help because this is a disaster as i cant afford the new hybrid batteries. Secondly is their any good machenic or workshop in rawalpindi or lahore (As i move to these cities frequently). Also if i take my car to Toyota motors for diagnostics, how much will they charge? Sorry guys alot of question but i am in a fix

    No it wasnt. This is something i checked thoroghly. i have gone from pindi to lahore once as it has only been 3 or 4 days. But I have checked the mileage a couple of times. I got the plugs changed today and nothing(if anything its running on battery even less). Please advice or give me contact number of a good mechanic. My number is 03135106547. My hesitation in going to toyota is one that will they be able to recalibrate it because i think it will solve the issue and second expenses. Can anyone give me idea of how much a checkup would cost(just a general idea)

    if the engine is fine then it can be batteries.
    better get it checked from Toyota

    Traffic is the problem!
    Wait for metro bus project in Islamabad to Finish ! My Insight dropped avg from 18-14 bcuz of metro bus!
    Secondly car wont perform good if you're doing short trips 2-5 km !
    Check air filter avg will get better , check for any check lamps! If its a non accidental car this issue should not exist

    Treat others the way you want to be treated

    what was the tool to check the batteries & where did he plugged that gauge ? If it was a common DVM with 2 probes only and test was performed in the engine bay HV box, without key in the ignition he is goof cheater. Prius Battery bank status can only be checked with a HV isolated probe by disconnecting the battery bank cable in rear of the vehicle. A circuit breaker disconnects the battery bank and a warning is mentioned wait 5 minutes before unplugging the HV cable assy. unless the vehicle is locally repaired without any standards and all warning decals & color coding is messed up.

    really? - people call a DVM a sort of scan tool?

    Well if anything didn't helped you then
    Your battery should've finished its lifetime and now the batteries are retaining charge and needs constant charging which is making engine to over work and results in less milage!
    Change your batteries , max cost 60k

    Treat others the way you want to be treated
    Always respect your parents

    actually changing Tyre profile change the geometery of the vehicle due to which its calculations are totally disturbed. Always Go for the recommended profile. Driving at least 10KM trip would give you best mileage and below 5KM will give you disappointing result.
