MAINTENANCE REQUIREMENTS255
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 an authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional. Any authorized
Toyota dealer 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
service or maintain your vehicle, we
recommend that you request that a record
of maintenance be kept.
The service interval for scheduled main-
tenance is determined by the odometer
reading or time interval, whichever
comes first, shown in the schedule.
Rubber hoses (for cooling and heater
system, brake system and fuel system)
should be inspected by a qualified tech-
nician in accordance with the Toyota
maintenance schedule.
They are particularly important mainte-
nance items. Have any deteriorated or
damaged hoses replaced immediately.
Note that rubber hoses will deteriorate
with age, resulting in swelling, chafing or
cracks.Be on the alert for changes in perfor-
mance, sounds, and visual tip−offs that
indicate service is needed. Some impor-
tant clues are as follows:
DEngine missing, stumbling, or pinging
DAppreciable loss of power
DStrange engine noises
DA leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
DChange in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaustsystem checked im-
mediately.)
DFlat−looking tire; excessive tire squeal
when cornering; uneven tire wear
DVehicle pulls to one side when driving
straight on a level road
DStrange noises related to suspension
movement
DLoss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
DEngine coolant temperature continually
higher than normal
If you notice any of these cues, take your
vehicle to any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, as soon as pos-
sible. It probably needs adjustment or re-
pair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.
