(Assuming 100k Miles and not 100km, which is about 62k Miles)
Someone correct me if I'm wrong, but I don't think there is a maint. interval for the timing belt on our cars (never heard of anyone with a problem in this area).
The plugs will need to be changed as part of the 105k miles service (check here
). When they are doing the plugs, have them check this TSB as well, which is a common problem on our cars:Check this before your powertrain warranty is up!
You may want to also figure out when the following services were done last: Transmission Drain and Refill, Brake Fuild Flush, Power Steering Flush, Coolant Drain and Refill, Rear Diff service.
I try to do all of the above at 30k intervals.
Other items to check on the suspension are common wear and tear things like front and rear endlinks, compression rod bushings and see if the struts/shocks are leaking (recommend replacing at 100k miles regardless as it makes a world of difference).
