Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota rec-
ommends that all maintenance service operations as well as other inspec-
tions and repairs be carried out by authorized Toyota dealers or repairers or
other duly qualified and equipped professionals. For repairs and services
covered by your warranty, please visit an authorized Toyota dealer or
repairer, who will use genuine Toyota parts in repairing any difficulties you
may encounter. There can also be advantages in utilizing authorized Toyota
dealers or repairers for non-warranty repairs and services, as members of
the Toyota network will be able to expertly assist you with any difficulties you
may encounter.
Your Toyota dealer or repairer, or another duly qualified and equipped
professional will perform all of the scheduled maintenance on your vehicle
reliably and economically due to their experience with Toyota vehicles.
Does your vehicle need repair?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon mon-
oxide leak. Drive with the windows open and have the exhaust system
checked immediately.)
