6-1. Maintenance and care  
Cleaning and protecting the vehicle  
exterior  
Perform the following to protect the vehicle and maintain it in  
prime condition:  
Working from top to bottom, liberally apply water to the vehicle  
body, wheel wells and underside of the vehicle to remove any dirt  
and dust.  
Wash the vehicle body using a sponge or soft cloth, such as a  
chamois.  
For hard-to-remove marks, use car wash soap and rinse thoroughly  
with water.  
Wipe away any water.  
Wax the vehicle when the waterproof coating deteriorates.  
If water does not bead on a clean surface, apply wax when the vehicle  
body is cool.  
Automatic car washes  
Fold the mirrors before washing the vehicle. Start washing from the front of  
the vehicle. Make sure to extend the mirrors before driving.  
Brushes used in automatic car washes may scratch the vehicle surface,  
parts (wheel, etc.) and harm your vehicle’s paint.  
In certain automatic car washes, the roof antenna (if equipped) or rear  
spoiler may interfere with machine operation. This may prevent the vehicle  
from being cleaned properly or result in damage to the antenna or rear  
spoiler.  
High pressure car washes  
As water may enter the cabin, do not bring the nozzle tip near the gaps  
around the doors or perimeter of the windows, or spray these areas continu-  
ously.

6-1. Maintenance and care  
Wheels and wheel ornaments  
Remove any dirt immediately by using a neutral detergent.  
Wash detergent off with water immediately after use.  
To protect the paint from damage, make sure to observe the following pre-  
cautions.  
• Do not use acidic, alkaline or abrasive detergent  
• Do not use hard brushes  
• Do not use detergent on the wheels when they are hot, such as after driv-  
ing or parking in hot weather  
Brake pads and calipers  
Rust may form if the vehicle is parked with wet brake pads or disc rotors,  
causing them to stick. Before parking the vehicle after it is washed, drive  
slowly and apply the brakes several times to dry the parts.  
Bumpers and side moldings  
Do not scrub with abrasive cleaners.  
Plated portions  
If dirt cannot be remove, clean the parts as follows:  
Use a soft cloth dampened with an approximately 5% solution of neutral  
detergent and water to clean the dirt off.  
Wipe the surface with a dry, soft cloth to remove any remaining moisture.  
To remove oily deposits, use alcohol wet wipes or a similar product.  
Notes for a smart key system  
6
If the door handle becomes wet while the electronic key is within the effective  
range, the door may lock and unlock repeatedly. In this case, follow the fol-  
lowing correction procedures to wash the vehicle:  
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehi-  
cle. (Take care to ensure that the key is not stolen.)  
• Set the electronic key to battery-saving mode to disable the smart key sys-  
tem. (P. 116)  
WARNING  
When washing the vehicle  
Do not apply water to the inside of the engine compartment. Doing so may  
cause the electrical components etc. to catch fire.  
Precautions regarding the exhaust pipe

When to replace your vehicle’s tires  
Tires should be replaced if:  
The treadwear indicators are showing on a tire.  
You have tire damage such as cuts, splits, cracks deep enough to  
expose the fabric, and 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 reg-  
istered, the tire pressure warning system will not work properly. After driv-  
ing for about 20 minutes, the tire pressure warning light blinks for 1  
minute and stays on to indicate a system malfunction.  
Tire life  
Any tire over 6 years old must be checked by a qualified technician even  
if it has seldom or never been used or damage is not obvious.  
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.

Maximum load of tire  
Check that the number given by dividing the maximum load by 1.10 of the  
replacement tire is greater than 1/2 of the Gross Axle Weight Ratings

Tire types  
6-3. Do-it-yourself maintenance  
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 install-  
ing snow tires, be sure to replace all four tires.  
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 com-  
pared with summer tires in highway driving.  
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 restrictions. Snow tires  
should be installed on all wheels. (P. 331)  
If the tread on snow tires wears down below 0.16 in. (4 mm)  
The effectiveness of the tires as snow tires is lost.  
Warning performance of the tire pressure warning system  
The warning of the tire pressure warning system will change in accor-  
dance with the conditions under which it was initialized. For this reason,  
the system may give a warning even if the tire pressure does not reach a  
low enough level, or if the pressure is higher than the pressure that was  
adjusted to when the system was initialized.

• A tire has been replaced with a tire that is not an OE (Original Equip-  
ment) tire.  
• A tire has been replaced with a tire that is not of the specified size.  
• Tire chains etc. are equipped.  
• If a window tint that affects the radio wave signals is installed.  
• If there is a lot of snow or ice on the vehicle, particularly around the  
wheels or wheel housings.  
• If the tire inflation pressure is extremely higher than the specified  
level.  
• If the spare tire is in a location subject to poor radio wave signal  
reception.  
• If a large metallic object which can interfere with signal reception is  
put near the spare tire.  
• If tires not equipped with the tire pressure warning valves and trans-  
mitters are used.  
• If the ID code on the tire pressure warning valves and transmitters is  
not registered in the tire pressure warning computer.  
Performance may be affected in the following situations.  
• Near a TV tower, electric power plant, gas station, radio station, large  
display, airport or other facility that generates strong radio waves or

Also, make sure the tires are cold before carrying out initialization or tire  
inflation pressure adjustment.  
If you have accidentally turned the engine switch off during initialization,  
it is not necessary to press the reset switch again as initialization will  
restart automatically when the engine switch has been turned to IGNI-  
TION ON mode for the next time.  
If you accidentally press the reset switch when initialization is not neces-  
sary, adjust the tire inflation pressure to the specified level when the  
tires are cold, and conduct initialization again.  
While the position of each tire is being determined and the inflation pres-  
sures are not being displayed on the multi-information display, if the  
inflation pressure of a tire drops, the tire pressure warning light will come  
on.  
When initialization of the tire pressure warning system has failed  
Do not move the vehicle backward during initialization. Initialization is  
started again from the beginning and it may take longer than usual.  
Initialization may take longer to complete if the vehicle is driven on an  
unpaved road.  
When performing initialization, drive on a paved road if possible.  
Depending on the driving environment and condition of the tires, initial-  
ization will be completed in approximately 10 to 30 minutes.  
• If initialization is not complete after driving approximately 30 minutes,  
continue driving for a while.  
• If initialization is not complete after driving approximately 1 hour, park  
the vehicle in a safe place for approximately 20 minutes. Then drive  
straight (with occasional left and right turns) at approximately 25 mph  
(40 km/h) or more* for approximately 10 to 30 minutes.  
• If initialization is still not complete, have the vehicle inspected by your  
Toyota dealer.  
*: Except when making a left/right turn  
In the following situations, the tire inflation pressure will not be recorded  
and the system will not operate properly. Perform initialization again.  
• When operating the tire pressure warning reset switch, the tire pres-

When removing or fitting the wheels, tires or the tire pressure warning  
valves and transmitters, contact your Toyota dealer as the tire pres-  
sure warning valves and transmitters may be damaged if not handled  
correctly.  
Make sure to install the tire valve caps. If the tire valve caps are not  
installed, water could enter the tire pressure warning valves and the  
tire pressure warning valves could be bound.  
When replacing tire valve caps, do not use tire valve caps other than  
those specified. The cap may become stuck.  
To avoid damage to the tire pressure warning valves and transmit-  
ters  
When a tire is repaired with liquid sealants, the tire pressure warning  
valve and transmitter may not operate properly. If a liquid sealant is  
used, contact your Toyota dealer or other qualified service shop as soon

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 or 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.  
It is difficult to judge if a tire is properly inflated based only on its appear-  
ance.  
It is normal for the tire inflation pressure to be higher after driving as  
heat is generated in the tire. Do not reduce tire inflation pressure after  
driving.  
Never exceed the vehicle capacity weight.  
Passengers and luggage weight should be placed so that the vehicle is  
balanced.  
WARNING  
Proper inflation is critical to save tire performance  
Keep your tires properly inflated.  
If the tires are not properly inflated, the following conditions may occur  
which could lead to an accident resulting in death or serious injury:  
Excessive wear  
Uneven wear  
Poor handling  
Possibility of blowouts resulting from overheated tires  
Air leaking from between tire and wheel  
Wheel deformation and/or tire damage  
Greater possibility of tire damage while driving (due to road hazards,  
expansion joints, sharp edges in the road, etc.)  
NOTICE  
When inspecting and adjusting tire inflation pressure  
Be sure to put the tire valve caps back on.  
If a valve cap is not installed, dirt or moisture may get into the valve and  
cause an air leak, resulting in decreased tire inflation pressure.

Wheels  
If a wheel is bent, cracked or heavily corroded, it should be  
replaced. Otherwise, the tire may separate from the wheel or  
cause a 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 the following:  
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.  
6
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 plas-  
tic or rubber hammer when balancing your wheels.

When replacing wheels  
6-3. Do-it-yourself maintenance  
The wheels of your vehicle are equipped with tire pressure warning  
valves and transmitters that allow the tire pressure warning system to  
provide advance warning in the event of a loss in tire inflation pressure.  
Whenever wheels are replaced, tire pressure warning valves and trans-  
mitters must be installed. (P. 430)  
WARNING  
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 a 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.  
When installing the wheel nuts  
Never use oil or grease on the wheel bolts or wheel nuts.  
Oil and grease may cause the wheel nuts to be excessively tightened, lead-  
ing to bolt or disc wheel damage. In addition, the oil or grease can cause the  
wheel nuts to loosen and the wheel may fall off, causing an accident and  
resulting in death or serious injury. Remove any oil or grease from the wheel  
bolts or wheel nuts.  
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.
