WARNING
Performing maintenance work
on a vehicle can be dangerous.
In trying to do some jobs, you can
be seriously injured. Do your own
maintenance work only if you

the proper tools and equipment
for the job. If you have any doubt,
see your dealer to have a
qualified technician do the work.

the best conditions, the engine oil
life system might not indicate the
need for vehicle service for more

reset. Your dealer has trained
service technicians who will perform
this work and reset the system.
