Maintenance and care
CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammation or skin cancer, so care should be taken to avoid
prolonged 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 dis-
pose of used oil and filters in househol d trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.
●Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on 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 every time you refill the vehicle.
●Be sure the engine oil filler cap is properly retightened.

CAUTION
■Chemicals in the battery
A battery contains poisonous and corrosive sulfuric acid and may produce hydro-
gen gas which is flammable and explosive. To reduce the risk of death or serious
injury, take the following precautions while working on or near battery:
●Do not cause sparks by touching the battery terminals with tools.
●Do not smoke or light a match near the battery.
●Avoid contact with eyes, skin and clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses when working near the battery.
●Keep children away from the battery.
■Where to safety charge the battery
Always charge the battery in an open area. Do not charge the battery in a garage or
closed room where there is not sufficient ventilation.
■How to recharge the battery
Only perform a slow charge (5A or less). The battery may explode if charged at a
quicker rate.
■Emergency measures regarding electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immediate medi-
cal attention. If possible, continue to apply water with a sponge or cloth while
traveling to the nearest medical facility.
●If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or a burning sensation, seek
medical attention immediately.
●If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the clothing and
follow the procedure above if necessary.
●If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Fo llow with milk of magnesia, beaten raw
egg or vegetable oil. Get emerge ncy medical attention immediately.

● Voltmeter continually points higher or lower than normal
■ Audible symptoms
●Changes in exhaust sound
● Excessive tire squeal when cornering
● Strange noises related to the suspension system
● Pinging or other noises related to the engine
■ Operational symptoms
●Engine missing, stumbling or running rough

5-2. Steps to take in an emergency
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch does not turn off the tire pressure warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks or tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light.
■If the tire pressure warning system is inoperative
The tire pressure warning system may become inoperative in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmitters are used.
●If the ID code on the tire pressure warning valves and transmitters is not regis-
tered.
●If electronic devices or facilities using similar radio wave frequencies are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If the tire pressure warning select switch is set to a different tire setting.
●If there is a lot of snow or ice on the vehicle, in particular around the wheels or
wheel housings.
●If non-genuine Lexus wheels are used.
●If tire chains are used.
●If the spare tire is in a location subject to poor radio wave signal reception.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or higher.
■If the tire pressure warning light blinks
If the tire pressure warning light blinks when the ignition key is turned to the “ON”
position, have it checked by your Lexus dealer.
■Changing the engine oil (U.S.A. only)
Make sure to reset oil change system

5-2. Steps to take in an emergency
CAUTION
■Replacing a flat tire
Observe the following precautions to reduce the risk of injury.
●Lower the spare tire completely to the ground before removing it from under the
vehicle.
●Do not try to remove the wheel ornament by hand. Take due care in handling the
ornament to avoid unexpected personal injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
The oil or grease can cause the wheel nuts to loosen, causing a serious accident.
Remove any oil or grease on the wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 97 ft•lbf (131 N•m, 13.4
kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the wheels
may fall off, which could lead to an accident causing death or serious injury.
●Do not attach a heavily damaged wheel orna ment, as it may fly off the wheel while
the vehicle is moving.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity:
● The 5W portion of the oil viscosity rating indicates the characteristic of
the oil which allows cold startability . Oils with a lower value before the W
allow for easier starting of the engine in cold weather.
● The 30 in 5W-30 indicates the oil viscosity when the oil is as its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load condition.
