Engine oil consumption  
The amount of engine oil consumed depends on the oil viscosity, the  
quality of the oil and the way the vehicle is driven.  
More oil is consumed under driving conditions such as high speeds, fre-  
quent acceleration and deceleration.  
A new engine consumes more oil.  
When judging the amount of oil consumption, keep in mind that the oil  
may have become diluted, making it difficult to judge the true level accu-  
rately.  
Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per  
1000 km). If the vehicle consumes more than this amount, contact your  
Toyota dealer.

Do not fail to initialize the tire  
pressure warning system  
after tire rotation.  
409  
4-3. Do-it-yourself maintenance  
The tire pressure warning system  
Your Toyota is equipped with a tire pressure warning system that  
uses tire pressure warning valves and transmitters to detect low  
tire inflation pressure before serious problems arise. (P. 468)  
Installing 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 tire pressure warning valve and transmitter ID codes  
must be registered in the tire pressure warning computer and tire  
pressure warning system must be initialized. Have tire pressure  
warning valve and transmitter ID codes registered by your Toyota  
dealer.  
Initializing the tire pressure warning system  
The tire pressure warning system must be initialized in the fol-  
lowing circumstances:  
When rotating the tires on vehicles differing with front and rear  
tire inflation pressures.  
When changing the tire inflation pressure by changing traveling  
speed or load weight, etc.  
When changing the tire size.  
When the tire pressure warning system is initialized, the current  
tire inflation pressure is set as the pressure benchmark.  
410  
4-3. Do-it-yourself maintenance  
How to initialize the tire pressure warning system  
STEP  
1
Park the vehicle in safe place and turn the “ENGINE START  
STOP” switch or the engine switch OFF.  
While the vehicle is moving, initialization is not performed.  
STEP  
2
Adjust the tire inflation pressure to the specified cold tire infla-  
tion pressure level. (P. 512)  
Make sure to adjust the tire pressure to the specified cold tire  
inflation pressure level. The tire pressure warning system will  
operate based on this pressure level.  
STEP  
STEP

STEP  
5
Vehicles with smart key system: Wait for a few minutes with  
the “ENGINE START STOP” switch in IGNITION ON mode,  
and then turn the “ENGINE START STOP” switch OFF.  
Vehicles without smart key system: Wait for a few minutes  
with the engine switch in the “ON” position, and then turn the  
engine switch to the “LOCK” position.  
411  
4-3. Do-it-yourself maintenance  
Registering ID codes  
The tire pressure warning valve and transmitter is equipped with a  
unique ID code.  
When replacing a tire pressure warning valve and transmitter, it is  
necessary to register the ID code of tire pressure warning valve and  
transmitter. Have the ID code registered by your Toyota dealer.  
When to replace your vehicle’s tires  
Tires should be replaced if:  
You have tire damage such as cuts, splits, cracks deep enough to  
expose the fabric or bulges indicating internal damage  
A tire goes flat repeatedly or cannot be properly repaired due to the  
size or location of a cut or other damage  
If you are not sure, consult with your Toyota dealer.  
Replacing tires and wheels  
If the ID code of the tire pressure warning valve and transmitter is not  
registered, the tire pressure warning system will not work properly. After  
about 20 minutes, the tire pressure warning light comes on after blinking  
for 1 minute to indicate a system malfunction.  
412  
4-3. Do-it-yourself maintenance  
Tire life  
Any tire over 6 years old must be checked by a qualified technician even  
if they have seldom or never been used or damage is not obvious.  
If the tread wears down below 0.16 in. (4 mm) on snow tires  
The effectiveness of snow tires is lost.  
Maximum load of tire  
Check that the maximum load of the replacement tire is greater than 1/2  
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the  
rear axle, whichever is greater.  
For the GAWR, see the Certification  
Label. For the maximum load of the  
tire, see the load limit at maximum cold  
tire inflation pressure mentioned on the  
sidewall of the tire. (P. 517)

413  
4-3. Do-it-yourself maintenance  
Tire types  
1 Summer tires  
Summer tires are high-speed performance tires best suited to highway  
driving under dry conditions. Since summer tires do not have the same  
traction performance as snow tires, summer tires are inadequate for  
driving on snow-covered or icy roads. For driving on snow-covered  
roads or icy roads, the use of snow tires is recommended. When  
installing snow tires, be sure to replace all four tires.  
2 All season tires  
All season tires are designed to provide better traction in snow and to  
be adequate for driving in most winter conditions, as well as for use  
year round. All season tires, however, do not have adequate traction  
performance compared with snow tires in heavy or loose snow. Also,  
all season tires fall short in acceleration and handling performance  
compared with summer tires in highway driving.  
3 Snow tires  
For driving on snow-covered roads or icy roads, we recommend using  
snow tires. If you need snow tires, select tires of the same size, con-  
struction and load capacity as the originally installed tires. Since your  
vehicle has radial tires as original equipment, make sure your snow  
tires also have radial construction. Do not install studded tires without  
first checking local regulations for possible restriction. Snow tires  
should be installed on all wheels. (P. 207)  
Initializing the tire pressure warning system  
Initialize the tire pressure warning system with the tire inflation pressure  
adjusted to the specified level.  
If you push the tire pressure warning reset switch accidentally  
If initialization is performed, adjust the tire inflation pressure to the speci-  
fied level and initialize the tire pressure warning system again.  
414  
4-3. Do-it-yourself maintenance  
When the initialization of the tire pressure warning system has  
failed  
Initialization can be completed in a few minutes. However, in the follow-  
ing cases, the settings have not been recorded and the system will not  
operate properly. If repeated attempts to record tire inflation pressure  
settings are unsuccessful, have the vehicle inspected by your Toyota  
dealer.  
When operating the tire pressure warning reset switch, the tire pres-  
sure warning light does not flash 3 times.  
After carrying out the initialization procedure, the tire pressure warn-  
ing light blinks for 1 minute then stays on after driving for about 20  
minutes.  
Routine tire inflation pressure checks  
The tire pressure warning system does not replace routine tire inflation  
pressure checks. Make sure to check tire inflation pressure as part of  
your routine of daily vehicle checks.

NOTICE  
Repairing or replacing tires, wheels, tire pressure warning valves  
and transmitters and tire valve caps  
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.  
When replacing tire valve caps, do not use tire valve caps other than  
those specified. The cap may become stuck.  
To avoid damaging the tire pressure warning valves and transmit-  
ters  
Do not use liquid sealants on flat tire.  
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.

.
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.  
Effects of incorrect tire inflation pressure  
Driving with incorrect tire inflation pressure may result in the following:  
Reduced fuel efficiency  
Reduced driving comfort and tire life  
Reduced safety  
Damage to the drive train  
If a tire needs frequent refilling, have it checked by your Toyota dealer.  
Instructions for checking tire inflation pressure  
When checking tire inflation pressure, observe the following:  
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.  
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.  
Do not bleed or reduce tire inflation pressure after driving. It is normal  
for the tire inflation pressure to be higher after driving.  
Never exceed the vehicle capacity weight.  
Passengers and luggage weight should be placed so that the vehicle  
is balanced.  
420  
4-3. Do-it-yourself maintenance  
CAUTION  
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.  
Excessive wear  
Uneven wear  
Poor handling  
Possibility of blowouts resulting from overheated tires  
Poor sealing of the tire bead  
Wheel deformation and/or tire separation  
A greater possibility of tire damage from road hazards  
NOTICE

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.  
421  
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.  
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 inset*.  
Replacement wheels are available at your Toyota dealer.  
*: Conventionally referred to as “offset”.  
Toyota does not recommend using:  
Wheels of different sizes or types  
Used wheels  
Bent wheels that have been straightened  
Aluminum wheel precautions  
Use only Toyota wheel nuts and wrenches designed for use  
with your aluminum wheels.  
When rotating, repairing or changing your tires, check that the  
wheel nuts are still tight after driving 1000 miles (1600 km).  
Be careful not to damage the aluminum wheels when using  
tire chains.  
Use only Toyota genuine balance weights or equivalent and a  
plastic or rubber hammer when balancing your wheels.  
422  
4-3. Do-it-yourself maintenance  
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. 410)  
CAUTION  
When replacing wheels  
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.  
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.  
4
NOTICE  
Replacing tire pressure warning valves and transmitters  
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 or other qualified service shop. In addition, make sure to  
purchase your tire pressure warning valves and transmitters at your  
Toyota dealer.  
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.
