Nissan Sentra Owners Manual: Maintenance requirements
Your NISSAN has been designed to have minimum maintenance requirements with long service intervals to save you both time and money; however, some day-to-day and regular maintenance is essential to maintain your NISSAN’s good mechanical condition as well as its emissions and engine performance.
It is the owner’s responsibility to make sure that the scheduled maintenance, as well as general maintenance, is performed.
As the vehicle owner, you are the only one who can ensure that your vehicle receives proper maintenance. You are a vital link in the maintenance chain.
Scheduled maintenance
For your convenience, both required and optional scheduled maintenance items are described and listed in your “NISSAN Service and Maintenance Guide”. You must refer to that guide to ensure that necessary maintenance is performed on your NISSAN at regular intervals.
General maintenance
General maintenance includes those items which should be checked during normal day-to-day operation.
They are essential for proper vehicle operation.
It is your responsibility to perform these maintenance procedures regularly as prescribed.
Performing general maintenance checks requires minimal mechanical skill and only a few general automotive tools.
These checks or inspections can be done by you, a qualified technician or, if you prefer, a NISSAN dealer.
Where to go for service
If maintenance service is required or your vehicle appears to malfunction, have the systems checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists who are kept up-to-date with the latest service information through technical bulletins, service tips and in-dealership training programs. They are completely qualified to work on NISSAN vehicles before they work on your vehicle rather than after they have worked on it.
You can be confident that a NISSAN dealer’s service department performs the best job to meet the maintenance requirements on your vehicle — in a reliable and economical way.
