tail lights are on and surrounding brightness levels, as shown in the table
below.
*: 22 levels of the brightness are displayed on the setting screen. However,
the brightness setting will be the brightest when other than 1st level (the

ness), even if the taillights are illuminated, the instrument cluster light will
not dim.

5787-2. Maintenance

Maintenance requirements
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, refer to the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself maintenance?
Many maintenance items are easy to do yourself if you have a little
mechanical ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools and
skills. These are best performed by qualified technicians. Even if you’re an
experienced do-it-yourself mechanic, we recommend that repairs and
maintenance be conducted by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. Any authorized Toyota retailer
or repairer will keep a record of maintenance, which could be useful should
you ever require Warranty Service. Should you choose to select a qualified
and equipped professional other than an authorized Toyota repairer to ser-
vice or maintain your vehicle, we recommend that you request that a
record of maintenance be kept.
To ensure safe and economical driving, day-to-day care and reg-
ular maintenance are essential. Toyota recommends the follow-
ing maintenance:

Maintenance and care
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota retailers or Toyota authorized
repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized Toyota retailer or repairer, who will use
genuine Toyota parts in repairing any difficulties you may encounter. There
can also be advantages in utilizing authorized Toyota retailers 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 retailer or Toyota authorized repairer, or any reliable repairer will
perform all of the scheduled maintenance on your vehicle reliably and eco-
nomically due to their experience with Toyota vehicles.
■Does your vehicle need repairs?
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 monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal (P. 661, 705)
If you notice any of these clues, take your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
sible. Your vehicle may need adjustment or repair.
