Maintenance and care
Wipe the vehicle body from top to bot-
tom.
If dirt persists ( P.257)
3Using another soft chamois
cloth, dry the vehicle while tak-
ing care to not rub the vehicle
body.
Make sure to remove any standing water before it evaporates.
Do not use the same chamois cloth that
was used to wash the vehicle (step 2).
■If dirt cannot be washed off with water alone
●Water stains
If liquid, such as rain water or tap water,
evaporates on a painted surface, dirt or
minerals in the liquid may be left behind.
If not cleaned off, the contaminants may
settle into the textured surface of the
matte clear coat, making it difficult to
clean off with water alone.
Contaminant
Citric acid
●In this case, to remove the contami- nants, use dilute citric acid.
Dissolve citric acid powder in distilled
water at the following ratio:
Citric acid powder: 5 to 10 g (0.01 to
0.02 lb.) (1 to 2 teaspoons)
Distilled water: 0.2L (0.2 qt., 0.2 Imp. qt.)
Thoroughly soak a soft chamois cloth in
the citric acid and place the chamois
cloth over the dirty area. Wait for the
contaminants to be dissolved by the
acid. Then, gently wipe the area several
times with the chamois cloth, taking care
to not rub the vehicle body. After that,
apply plenty of water to the area to wash
off the contaminants and acid.
●Dead insects, bird droppings, and oil stains
If these materials are not cleaned off,
contaminants, such as proteins and oil,
may settle into the textured surface of
the matte clear coat, making it difficult to
clean off with water alone.

■Where to go for maintenance ser-
vice?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service opera- tions 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 per- form all of the scheduled maintenance on your vehicle reliably and economi-
cally due to their experience with Toyota vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance
schedule.
For full details of your maintenance
schedule, read the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the 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 experi-
enced do-it-yourself mechanic, we rec-
ommend 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 War-
ranty Service. Should you choose to
select a qualified and equipped profes-
sional other than an authorized Toyota
repairer to service or maintain your
vehicle, we recommend that you
