required maintenance using
genuine replacement parts.
They have up-to-date tools
and equipment for fast and
accurate diagnostics. Many
dealers have extended
evening and Saturday hours,
courtesy transportation, and
online scheduling to assist

importance of providing
competitively priced
maintenance and repair
services. With trained
technicians, the dealer is the
place for routine maintenance
such as oil changes and tire
rotations and additional
maintenance items like tires,
brakes, batteries, and wiper
blades.
Caution
Damage caused by improper
maintenance can lead to
costly repairs and may not
be covered by the vehicle
warranty. Maintenance
intervals, checks,
inspections, recommended
fluids, and lubricants are
important to keep the
