How to trun off the beep when in reverse?

[whiteprius]

Is there a simple to turn off that annoying beeping when the car is in reverse?

[eak354]

to turn off reverse beep:

Power on (not necessarily ready, IG-ON will do).
Set Trip/ODO to ODO
Power off.
Power on to ready (brake on).
Within 6 seconds, press and hold ODO for 10 seconds or more.
WHILE STILL HOLDING ODO *after* 10 seconds, Shift from P to R, then back to P. Now release ODO.
You'll see in the trip display "b on" or "b off".
Press ODO to toggle.
Now power off.

enjoy the silence! :wink:

Wow! How did you ever figure this out? Is there some sort of StarTrek Manual for the Prius for this????

Thanks,

Problem. Tried to turn off the Backup Beep today. It did not work. This Prius is a 2005 and the gear shift does not go to P, only R N and D

Is there a similar set of directions for the Prius 2005 or is there something different I need to do since I cannot "shipt" into P, but need to press the P button.

Please advise.

Thanks,

The 2004 and 2005 Prius both have the same shift lever and P button. So just use the P button when it says Shift into P, and use the Shift lever to R when it says Shift into R.

The point is to perform the activity for which you wish to turn beeping on or off. If you try the seatbelt beeper procedure, you will see it is similar but you are fastening and unfastening the seat belt instead of shifting.

The only problem with the seatbelt reminder is that it can't be turned off in the newer cars. The display toggles between b-off and b-on, but it doesn't change anything, the seatbelt beeper still beeps. Thankfully the reverse beeper can be disabled (and has been).

Speaking of the secret Federation Prius Manual, there was an article in this months Car and Driver about the Prius running at Bonneville. It was pretty interesting, but what really intrigued me was how the driver was able to turn off the traction control. Apparently there are methods to turn on and off features in discrete ways. For the traction control, it was a combination of pressing on the brake once, and the accelerator three times. The article didn't go into details, but I would assume that it would be in IG-ON mode and might require something like the ODO button being pressed.

Anyone else heard of these codes, and better yet, anyone know any of them?

OK, here's some informationn from the repair manual. However, it does state that spinning the front wheels can damage the vehicle (see part I bolded). Do this at your own risk.
This will disable the TRAC and keep the engine running.

5. INSPECTION MODE
HINT:

The PRIUS’ engine automatically stops if the vehicle is stopped, the engine is warmed up, the battery
is well charged, and A/C compressor operation is not being used. Activate inspection mode when continuous
operation of the engine is required.

The PRIUS has a motor TRAC function. When the wheel speed of the front wheels exceeds that of
rear wheels, the wheel speed of the front wheels is restrained. It is necessary to activate inspection
mode and deactivate the motor TRAC function when turning only the front wheels using a speedometer
tester.
(a) Vehicle conditions
(1) Before activating inspection mode, turn the air conditioning off, start the engine with the selector
lever in the P position, and check that the engine stops within several seconds after starting (engine
warm up check).
(2) Activate inspection mode and inspect the vehicle. The shift position for each test is as follows:
Test item Shift position Inspection mode
1. Vehicle straight travelling test
(side slip inspection)
D ON or OFF
2. Breaking force test N ON or OFF
3. Speed meter test D ON
4. Exhaust gas test (idling) P ON
5. Headlight test P ON or OFF
(3) Reset inspection mode immediately after completion of inspection.
NOTICE:
Driving the vehicle without resetting inspection mode may damage the transaxle.
( Special notes for speedometer test
NOTICE:
Do not use the speedmeter tester to perform rapid starting or quick accleration/deceleration without
first setting the proper load on the vehicle. Failing to set the load may damage the transaxle.
(1) Depress the accelerator pedal slowly and gradually accelerate the vehicle. Make a measurement.
(2) After the measurement, use the brake to gradually decelerate the vehicle.
© Special note for using the chassis dynamometer
Always set an appropriate load before starting the test.
(d) Activating of inspection mode (NOT Using the hand–held tester)
Perform the following steps from (1) through (4) in 60 seconds.
(1) Turn the power switch ON (IG).
(2) Fully depress the accelerator pedal twice with the
transmission in the P position.
(3) Fully depress the accelerator pedal twice with the
transmission in the N position.
(4) Fully depress the accelerator pedal twice with the
transmission in the P position.
(5) Check that the HV system warning lamp flashes on
the multi–information display.
(6) Start the engine by pushing the power switch, depressing
the brake pedal.

NOTICE:

The idling speed in inspection mode is approximately
1,000 rpm. The engine speed increases to 1,500 rpm
if the accelerator pedal is depressed by less than
60%. If the accelerator pedal is depressed by more
than 60%, the engine speed increases to 2,500 rpm.

If a DTC is set during inspection mode, the master
warning lamp and the error warning lamp illuminate
on the multi–information display.

When the master warning lamp illuminates during inspection
mode, deactivate inspection mode, and
check a DTC(s).

Driving the vehicle without deactivating inspection
mode may damage the transaxle.
