■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 authoriz ed 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 or clutch pedal,
pedal almost touches the floor, vehicle pulls to one side when braking
● Engine coolant temperature continually higher than normal
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.

Maintenance and care
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.
Remove the sand and dust from around the dipstick.
Holding a rag under the end,
pull the dipstick out.
Wipe the dipstick clean.
Make sure that the inlet of the oil level gauge guide and O-ring of the
dipstick are free from sand and dust.
If the O-ring is damaged, replace it with a new one.
