Air filters

Elle is correct. Check your Owner's Manual. You'll find the "Severe"
schedule mentioned somewhere on the pages near the schedule chart.There is
no separate chart for "Severe".

 

Owner's manuals for U.S. Hondas have made this distinction for decades
now. From googling, it seems Toyotas also make this distinction.

I have owned three different generations of Civics over 20 years now.
Been working on them for ten+ years.

What make of car did you drive before?

 

Yes, for fluids and filters, but not for the timing belt. I just checked
my Owner's Manual again.

 

I see at the online U.S. 1994 Accord Coupe owners' manual linked below
that I am wrong and for timing belts, there is no distinction made in
the actual owners' manual. Same for 1991 Civics.

I do not know why Autozone's site, which pertains to U.S. cars, shows
two different maintenance schedules for the 94 Accord and other
Hondas, one for normal and one for severe, with a 60k interval for the
Accord under severe conditions. The American Honda site (under
"Owner's Link") does not list any change interval for the timing belt
for older Civics and Accords, though going to the owners' manual at
rjanisis above shows, again, no distinction for timing belts.

I checked too, and I'm also wrong, at least about the OP's 4-cylinder
Accord and other 4-cylinder Hondas.

It turns out that it's the newer V6 models that have a dual schedule: If
the vehicle is driven "regularly" at temperatures over 110F, or below -20F,
then the 60K interval is followed instead of the 90K interval.
