The second belt drives the supercharger. Each belt has
its own tensioner and idler pulley. See “Maintenance

Maintenance Schedule
I Short Trip/City Definition
Follow the Short Trip/City Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
0 Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
0 Most. trips are through dusty areas.
You frequently tow a trailer or use a carrier on top
of your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down soonel:

Change (or
3 months, whichever occurs first).
Every 6,000 Miles (10 000 km): Chassis Lubrication
