Q Handling the suspension
Do not modify the suspension, as changes to the height or incli ne of the
vehicle may prevent the sensors from correctly detecting obstac les, may
cause the system not operate, or may cause the system to operat e unnec-

WARNING
QWhen the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stabilit y and driving
force, do not turn the TRC/VSC systems off unless necessary.
Q Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if dif ferent tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer for further information when replacing tires or wheels.
Q Handling of tires and the suspension

Maintenance and care
QWhere 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

that indicate service is needed. Some important clues are:
OEngine missing, stumbling or pinging
OAppreciable loss of power
OStrange engine noises
OA fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
OChange in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
OFlat-looking tires, excessive tire squeal when cornering, uneven tire wear
OVehicle pulls to one side when driven straight on a level road
OStrange noises related to suspension movement
OLoss of brake effectiveness, spongy feeling brake pedal, pedal almost

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 661)
XInstalling tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter ID
codes registered by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. (P. 603)
XInitializing the tire pressure warning system
QThe tire pressure warning system must be initialized in the fol-
lowing circumstances:
OWhen rotating front and rear tires which have different tire infla-
tion pressures
OWhen the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
