Before driving
CAUTION
SRS airbag precautions
If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
The SRS side airbag and SRS curtain shield airbag are designed only to
be a supplement to the primary protection provided by the seat belt. They
do not do away with the need to fasten seat belts. It is also important to
wear your seat belt to help avoid injuries that can result when an occupant
is not seated in a proper upright position.
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing
death or serious injury.
Installation, removal, disassembly and repair of the SRS airbags.
Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails.
Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment.
Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches.
Modifications to the vehicle's suspension system.
Installation of electronic devices such as mobile two-way radios and CD
players.
Installation of electronic devices such as an RF-transmitter and CD play-
ers.
Modifications to your vehicle for a person with a physical disability.

168 2-1. Driving procedures
NOTICE
Avoiding damage to vehicle parts
Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
On vehicles with an automatic transmission, do not race the engine for
more than 5 seconds in any position except the N or P position when the
brake is applied or when chocks are used in the wheels. This may cause
the transmission fluid to overheat.
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.
The vehicle will lean abnormally.
Information on what to do in case of a flat tire (P. 384, 393)
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
Engine stalling
Short in electrical components
Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional check the following:
Brake function
Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, differential, etc.
Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible) and the function of all joints, bearings, etc.

230 2-4. Using other driving systems
CAUTION
When the VSC and/or brake LSD function is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
Replacing tires
Make sure that all tires are of the specified size, brand, tread 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 different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

236 2-5. Driving information
CAUTION
Driving with tire chains
Vehicles with an emergency tire puncture repair kit: When any of the tires
are punctured, you can seal the tire temporarily. However, do not use the
tire chain on a sealed tire. If any of the rear tires are punctured although it
is required to use tire chains, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
• Do not drive in excess of the speed limit specified for the tire chains
being used, or 30 km/h (19 mph), whichever is lower.
• Avoid driving on bumpy road surfaces or over potholes.
• Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
• Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
Always use the utmost care when driving with tire chains - overconfidence
because you are driving with tire chains could easily lead to a serious acci-
dent.
NOTICE
Using the tire chains
Use only chains that are of the correct size for your tires so as not to damage
the vehicle body or suspension.
Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

292 4-2. Maintenance
Where to go for maintenance service?
In order to maintain your vehicle in the highest possible condition, Toyota
recommends that all repairs and service operations be carried out by autho-
rized Toyota dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an
authorized Toyota dealer or repairer, who will use genuine Toyota parts in
repairing any difficulties you may encounter. There can also be advantages
in utilizing authorized Toyota dealers 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 dealer or repairer, or another duly qualified and equipped pro-
fessional service department will perform all of the scheduled maintenance
on your vehicle - reliably and economically 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 mon-
oxide 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
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.
