Toyota Corolla (E210): Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular maintenance are essential. It is the owner's responsibility to perform regular checks.
Toyota recommends the maintenance below.
■Repair and replacement
It is recommended that genuine Toyota parts be used for repairs to ensure performance of each system.
If non-Toyota parts are used in replacement or if a repair shop other than a Toyota dealer performs repairs, confirm the warranty coverage.
■Allow inspection and repairs to be performed by a Toyota dealer
- Toyota technicians are well-trained specialists and are kept up to date with the latest service information. They are well informed about the operation of all systems on your vehicle.
- Keep a copy of the repair order. It proves that the maintenance that has been performed is under warranty coverage. If any problem should arise while your vehicle is under warranty, your Toyota dealer will promptly take care of it.
WARNING

Improper maintenance could result in serious damage to the vehicle and possible death or serious injury.
