Are you sure, there should be a rubber plug you remove, then you insert anything that will fit and reset the button behind.

Hi Brett,
Is there a grommet on your dash/speedo face?
If there is, pull that out, then get a pen and pull the ink stick out of it, or a thin piece of wire and poke through the dash into a slot/button hole, this asuming it is the same as an 80 series.
If it;s not sorry I can't help. ;(

G'day agin Brett,
Give your local Toyota dealer a ring in the morning, I'm sure they'll be able to help you.
I had no idea how to reset mine after having the head off and belt changed, the warning light came on, one day while I was in town, dropped into the dealer and he told me how to do mine.
You'll get it sorted,

I replaced mine a few weeks back too. Its got 149,700 on the speedo - I'm just waiting for mine to tick over 150, 000 so I can see the light come on :-))

79series have the electronic speedo. Its the same technique as the 100series - I've lifted the following off LCOOL:

1. T-BELT MODE DISPLAY
a) With ignition turned ON, using the trip switch (select/reset button) change the display to ODO, and turn the ignition OFF
b) While pressing the trip switch, turn the ignition switch ON and hold it for 5 seconds.
c) Release the trip switch, then press the switch again within 5 seconds.
d) The digital display should change to T-belt mode. The initial display "15" (0,000km) is displayed (ie. 150,000km).

2. REWRITING REPLACEMENT VALUES
While in the T-Belt mode, each press of the trip switch will change the displayed value by 10,000km increments. Once " 20 " (200,000km) is reached the display reverts back to " 1 " (10,000km) again. Remember, this setting is the number of kilometres to be travelled before the light comes on next, and once reset this counter will start from zero.

I believe the timing belt interval for all the 100 series engine variants is 150,000km, but this should be checked against each different markets servicing recommendation. This being the case, you shouldn't need to change from the default setting of "15".

3. T-BELT WARNING RESET COMPLETION
a) After setting the replacement setting value, hold the trip switch ON for more than 5 seconds then release the switch.
b) Check that the display has now changed back to ODO and that the warning light has gone off when the engine is started.

NOTE: If the T-Belt mode is completed, even though the belt replacement has not been performed, the T-Belt warning IS reset.

I hope this proves to be of assistance guys, as usual all care no responsibility. ;-)

Happy to help Brett. I've posted this info a few times over the years - usually after others have said to remove the grommet or pull the speedo out and move the screw - because these were the methods used on the mechanical speedos on previous models. Enjoy your trip!

Just remember that the timing belt LIGHT is not important.
It is the bearing that is very important, while you got that far.
