The tire pressure warning system may become inoperative in the following conditions:
(When the condition becomes normal, the system will work properly.)
l If tires not equipped with tire pressure warning valves and transmitters are used.
l If the ID code on the tire pressure warning valves and transmitters is not regis-
tered.
l If electronic devices or facilities using similar radio wave frequencies are nearby.
l If a large metallic object which can interfere with signal reception is put in the
trunk.
l If a radio set at similar frequencies is in use in the vehicle.
l If a window tint that affects the radio wave signals is installed.
l If there is a lot of snow or ice on the vehicle, in particular around the wheels or
wheel housings.
l If non-genuine Lexus wheels are used.
l If tire chains are used.

l If the spare tire is in a location subject to poor radio wave signal reception.
l If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or higher.
If the tire pressure warning light comes on after blinking for 1 minute frequently
when the engine switch is turned to IG-ON mode, have it checked by your Lexus
dealer.

5-2. Steps to take in an emergency
CAUTION
n Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [tire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS-tire pressure warning system) that illuminates a low tire
pressure telltale (tire pressure warning light) when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale (low tire
pressure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).
NOTICE
n Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pressure warning system may not operate properly.

removing tire chains.
l Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing tires
on this vehicle.
l Always check that the tire jack is securely set to the jack point.
l Do not put any part of your body under the vehicle supported by a jack.
l Do not start or run the engine while your vehicle is supported by the jack.
l Do not raise the vehicle while someone is in it.
l When raising the vehicle, do not put an object on or under the jack.
l Do not raise the vehicle to a height greater than that required to replace the tire.
l Use a jack stand if it is necessary to get under the vehicle.
l Vehicles with electronically modulated air suspension: Be sure to turn off the
height control and stop the engine.
Take particular care when lowering the vehicle to ensure that no one working on or
near the vehicle may be injured.
n Replacing a flat tire
Observe the following precautions to reduce the risk of death or serious injury.
l 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.
l Have the wheel nuts tightened with a torque wrench to 103.3 ft•lbf (140 N•m,
14.3 kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the wheels

CAUTION
n To prevent an accident or injury when inspecting under the hood of your vehicle
l Keep hands and clothing away from the fan and other belts while the engine is
running.
l Do not loosen the coolant reservoir cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam released
under pressure.
NOTICE
n When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too quickly
can cause damage to the engine.

stuck in mud, dirt, or snow.
STEP 1
STEP 2
STEP 3
STEP 4
STEP 5
Stop the engine. Set the parking brake and put the selector
lever in P.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the engine.
Shift the shift lever to the D or R position and carefully apply
the accelerator to free the vehicle.
Turn off TRAC/VSC if these functions are hampering your attempts
to free the vehicle. (→ P. 175)
CAUTION
n When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the surrounding area is clear, to avoid striking other vehicles, objects or persons. The vehicle
may also lunge forward or lunge back suddenly as it becomes free. Use extreme
caution.
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
NOTICE
n To avoid damaging the transmission and other components
l Avoid spinning the wheels and do not rev the engine.
l If the vehicle remains stuck after trying these procedures, the vehicle may require
towing to be freed.
