CAUTION

n Tire pressure warning system operation

The tire pressure warning system may not provide warning immediately if a tire bursts or if sudden air leakage occurs.

n When inspecting or replacing tires

Observe the following precautions to prevent accidents. Failure to do so may cause damage to parts of the drive train, as well as dangerous han- dling characteristics, which may lead to fatal or injury accidents. l Do not mix tires of different makes, models, tread patterns or tread-

wear.

l Do not use tire sizes other than those recommended by Toyota. l Do not mix radial, bias-belted, or bias-ply tires. l Do not mix summer, all season and winter tires. l Do not use tires that have been used on another vehicle. l Do not use tires if you do not know how they were used previously.

n When initializing the tire pressure warning system

Do not push the tire pressure warning reset switch without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pres- sure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.

4-3. Do-it-yourself maintenance

NOTICE

n Repairing or replacing tires, wheels and tire pressure warning

valves and transmitters l When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact your Toyota dealer as the tire pressure warning valve and transmitter may be damaged if not handled cor- rectly.

l When replacing tires, make sure also to replace the tire pressure

warning valve and transmitter grommets.

n To avoid damaging the tire pressure warning valves and transmit-

ters Do not use liquid sealants on flat tires.

n Driving on rough roads

Take particular care when driving on roads with loose surfaces or pot- holes. These conditions may cause losses in tire inflation pressure, reducing the cushioning ability of the tires. In addition driving on rough roads may cause damage to the tires themselves, as well as the vehicle’s wheels and body.

n If tire inflation pressures become low while driving

Do not continue driving, or your tires and/or wheels may be ruined.

STEP 6

Remove the tire valve cap. Press the tip of the tire pressure gauge onto the tire valve. Read the pressure using the graduations of the gauge. If the tire inflation pressure is not within the recommended levels, adjust tire pressure. If you add too much air, press the center of the valve to lower. After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage. Reinstall the tire valve cap.

n Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least once a month. Do not forget to check the spare.

n Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following: l Reduced fuel efficiency l Reduced driving comfort and tire life l Reduced safety l Damage to the drive train If a tire needs frequent refilling, have it checked by your Toyota dealer.

n Instructions for checking tire inflation pressure

When checking tire inflation pressure, observe the following: l Check only when the tires are cold.

If your vehicle has been parked for at least 3 hours and has not been driven for more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading.

l Always use a tire pressure gauge.

The appearance of the tire can be misleading. In addition, tire infla- tion pressures that are even just a few pounds off can degrade ride and handling.

l Do not bleed or reduce tire inflation pressure after driving. It is normal

for the tire inflation pressure to be higher after driving.

l Never exceed the vehicle capacity weight.

Passengers and luggage weight should be placed so that the vehicle is balanced.

CAUTION

n Proper inflation is critical to save tire performance

Keep your tires properly inflated. Otherwise, the following conditions may occur and result in an accident causing death or serious injury. l Excessive wear l Uneven wear l Poor handling l Possibility of blowouts resulting from overheated tires l Poor sealing of the tire bead l Wheel deformation and/or tire separation l A greater possibility of tire damage from road hazards

NOTICE

n When inspecting and adjusting tire inflation pressure

Be sure to reinstall the tire valve caps. Without the valve caps, dirt or moisture could get into the valve and cause air leakage, which could result in an accident. If the caps have been lost, replace them as soon as possible.

4-3. Do-it-yourself maintenance Wheels

If a wheel is bent, cracked or heavily corroded, it should be replaced. Otherwise, the tire may separate from the wheel or cause loss of handling control. n Wheel selection

When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width, and offset. Replacement wheels are available at your Toyota dealer. Toyota does not recommend using: l Wheels of different sizes or types l Used wheels l Bent wheels that have been straightened

n Aluminum wheel precautions

l Use only Toyota wheel nuts and wrenches designed for use

with your aluminum wheels.

l When rotating, repairing or changing your tires, check that the

wheel nuts are still tight after driving 1000 miles (1600 km).

l Be careful not to damage the aluminum wheels when using

tire chains.

l Use only Toyota genuine balance weights or equivalent and a

plastic or rubber hammer when balancing your wheels.

4-3. Do-it-yourself maintenance

n When replacing wheels

The wheels of your Toyota are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advanced warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be installed. (→P. 376)

CAUTION

n When replacing wheels

l Do not use wheels that are a different size from those recommended in

the Owner’s Manual, as this may result in loss of handling control.

l Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing so may result in an accident, causing death or seri- ous injury.

NOTICE

n Replacing tire pressure warning valves and transmitters

l Because tire repair or replacement may affect the tire pressure warn- ing valves and transmitters, make sure to have tires serviced by your Toyota dealer. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Toyota dealer.

l Ensure that only genuine Toyota wheels are used on your vehicle.

Tire pressure warning valves and transmitters may not work properly with non-genuine wheels.

CAUTION

n Replacing light bulbs

l Turn off the headlights. Do not attempt to replace the bulb immediately

after turning off the headlights. The bulbs become very hot and may cause burns.

l Do not touch the glass portion of the light bulb with bare hands. Hold the

bulb by the plastic or metal portion. If the bulb is scratched or dropped it may blow out or crack.

l Fully install light bulbs and any parts used to secure them. Failing to do so may result in heat damage, fire, or water entering the headlight unit. This may damage the headlights or cause condensation to build up on the lens. l Do not take apart or repair the low beam discharge headlight bulbs, con-

nectors, power supply circuits, or related components. Doing so could result in electric shock and death or serious injury.

n High-intensity discharge (HID) headlights

l Contact your Toyota dealer before replacing high-intensity discharge

headlights (including light bulbs).

l Do not touch the high-intensity discharge headlight’s high voltage socket when the headlights are turned on. An extremely high voltage of 20000V will be discharged and could result in death or serious injury by electric shock.

If towing is necessary, we recommend having your vehicle towed by your Toyota dealer or a commercial towing service, using a lift-type truck or a flat bed truck. Use a safety chain system for all towing, and abide by all state/pro- vincial and local laws. If towing from the front, the vehicle’s rear wheel and axles must be in good condition. (→P. 417) If they are damaged, use a towing dolly or flat bed truck.

Before towing

The following may indicate a problem with your transmission. Contact your Toyota dealer before towing. l The hybrid system is operating, but the vehicle will not move. l The vehicle makes an abnormal sound.

Emergency towing

If a tow truck is not available, in an emergency your vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet. This should only attempted on hard, surfaced roads for short distances below 18 mph (30km/h). A driver must be in the vehicle to steer and operate the brakes. The vehicle’s wheels, drive train, axles, steering and brakes must be in good condition.

5-1. Essential information Event data recorder

Your vehicle has computers that monitor and control certain aspects of your vehicle. These computers assist in driving and maintaining optimal vehicle performance. Besides storing data useful for troubleshooting, there is a system to record data in a crash or a near car crash event. This is called an Event Data Recorder (EDR).

In a crash or a near car crash event

The SRS airbag sensor assembly contains the EDR. In a crash or a near car crash event, this device may record some or all of the follow- ing information: l Gasoline engine speed l Whether the brake pedal was applied or not l Vehicle speed l To what extent the accelerator pedal was depressed l Position of the transmission shift lever l Whether the driver and front passenger wore seat belts or not l Driver’s seat position l SRS airbag deployment data l SRS airbag system diagnostic data l Front passenger’s occupant classification The information above is intended to be used for the purpose of improving vehicle safety performance. Unlike general data recorders, the EDR does not record sound data such as conversation between passengers.
