my 80 has a hole in dash perspex to the left of trip meter reset button as you mentioned. Am pretty sure this question is in the archives somewhere if you're in a hurry. Failing that someone will get back to you I'm sure

this was asked on 70scool
and it if your 79series has the electronic speedo, then the following is the answer you require.

2002 HDJ79


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).


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 ".

Obviously for the US, the ODO is in miles, and I guess the T-Belt warning
would be set in 10,000 mile intervals.


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.
