WARNING
■If a safety system warning light
does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the engine, this could mean that these systems are not available to help protect you in
an accident, which could result in death or serious injury. Have the vehi-cle inspected by any authorized Toy-
ota retailer or Toyota authorized repairer, or any reliable repairer immediately if this occurs.
NOTICE
■To prevent damage to the engine and its components
The engine may be overheating if the high engine coolant temperature warning light flashes or turns on. In
this case, immediately stop the vehi- cle in a safe place, and check the
engine after it has cooled completely. ( P.339)

4-6. Driving tips
4-6.Driving tips
Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
 Have a service technician
inspect the condition of the bat-
tery.
 Have the vehicle fitted with four
snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size
and brand, and that chains match the
size of the tires*.
*: Tire chains cannot be mounted on
18-inch tires.
Winter driving tips
Carry out the necessary prepa-
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents. Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the size specified.
( P.350)
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (except
18-inch tires)
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehi- cle 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 50 km/h (30 mph), whichever is lower.
●Avoid driving on bumpy road sur-faces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
●Slow down sufficiently before enter-ing a curve to ensure that vehicle control is maintained.
●Do not use LTA (Lane Tracing Assist) system.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

6-2. Maintenance
request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
●Engine misses (misfire), stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox- ide 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 (vehicles with manual transmission),
pedal almost touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continu-ally higher than normal ( P.304)
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 possi-
ble. Your vehicle may need adjustment
or repair.

WARNING
The engine compartment contains many mechanisms and fluids that
may move suddenly, become hot, or become electrically energized. To avoid death or serious injury, observe
the following precautions.
■When working on the engine
compartment
●Keep hands, clothing and tools away from the moving fan and
engine drive belt.
●Be careful not to touch the engine,
radiator, exhaust manifold, etc. right after driving as they may be hot. Oil and other fluids may also be hot.

6-3. Do-it-yourself maintenance
WARNING
●Do not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel or the battery. Fuel and battery fumes are flammable.
●Be extremely cautious when work-ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
●Take care because brake fluid can
harm your hands or eyes and dam- age painted surfaces. If fluid gets on your hands or in your eyes, flush
the affected area with clean water immediately.If you still experience discomfort,
consult a doctor.
■When working near the electric
cooling fan or radiator grille
Be sure the engine switch is OFF. With the engine switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.261)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.If the reservoir needs frequent refill-
ing, it may indicate a serious problem.

WARNING
■Used engine oil
●Used engine oil contains poten-
tially harmful contaminants which may cause skin disorders such as inflammation and skin cancer, so
care should be taken to avoid pro- longed and repeated contact. To remove used engine oil from your
skin, wash thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of used oil and fil-
ters in household trash, in sewers or onto the ground.Call any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer, service station or auto parts store for information
concerning recycling or disposal.
●Do not leave used engine oil within
the reach of children.
NOTICE
■To prevent serious engine dam- age
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on
the vehicle components.
●Avoid overfilling, or the engine
could be damaged.
●Check the oil level on the dipstick

If the level is on or below the (LOW)
line, add coolant up to the (FULL)
line. ( P.339)
■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: - 35°C [-31°F])
For more details about coolant, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses,
engine coolant reservoir caps and water pump.If you cannot find a leak, have any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer, test the cap and check for leaks
in the cooling system.
Check the radiator, condenser clear
away any foreign objects. If either
of the above parts is extremely dirty
or you are not sure of their condi-
tion, have your vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap.
The cooling system may be under pressure and may spray hot coolant if
the cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or
paint.
Checking the radiator, con-
denser
WARNING
■When the engine is hot
Do not touch the radiator or con- denser as they may be hot and cause serious injuries, such as burns.
