2. Press gas pedal to floor(feel little button go click)
3. Hold for 5 seconds
4. Keep pedal to floor and turn key to off
5. Release gas pedal
6. Wait 2 minutes and then start car.

DONE!

You can do a throttle reset without disconnecting the battery. That's all the ecu is going to relearn unless you have a check engine light for a code.

Here's how to reset the FSS
The counter can also be reset by any individual after the indicated service has been performed.
Perform the following to reset the counter:
1. Turn the ignition key to the ON/RUN position.
2. Within one second press the ****/button to the left of the display twice.
3. The present status for days remaining or distance traveled is displayed. Within ten seconds turn the key to
OFF.
4. Press and hold the ****/button to the left of the display, while turning the key to ON/RUN again. The present
status for days remaining or distance traveled is displayed once more. Continue to hold the ****/button to the left
of the display.
5. Release the ****/button to the left of the display. After approximately ten seconds, a tone sounds and the
display shows 7,000 miles (11,000 km) for approximately ten seconds.
If the FSS counter was inadvertently reset, the counter must be reset.
The message is displayed for approximately ten seconds when turning the key to the ON/RUN position, or while
driving when reaching the service warning threshold. It can be cancelled manually by pressing the ****/button to
the left of the display.
Once the suggested term has passed, the message, plus either the symbol for Service A or the symbol for Service
B preceded by a “–” (minus symbol) blinks for approximately thirty seconds and a tone sounds every time when
turning the key to the ON/RUN position.
The FSS display can also be called up for approximately ten seconds with the display illuminated by pressing the
****/button to the left of the display twice within one second.
Note: When disconnecting the battery for one or more days at a time, such days will not be counted. Any
such days not counted by the FSS can be added.
The interval between services is determined by the type of vehicle operation. Driving at extreme speeds, and cold
starts combined with short distance driving in which the engine does not reach normal operating temperature,
reduce the interval between services.
