■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 in formation 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 moni-
toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure
telltale (tire pressure warning light) when on e or more of your tires is significantly
under-inflated. Accordingly, when the low ti re pressure telltale (tire pressure warning
light) illuminates, you should stop and check yo ur tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated 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).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS
(tire pressure warning system) malfunction indicator is combined with the low tire pres-
sure telltale (tire pressure warning light). When the system detects a malfunction, the
telltale will flash for approximately one minu te and then remain continuously illumi-
nated. This sequence will continue upon su bsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning system) from functioning properly. Always
check the TPMS (tire pressure warning syst em) malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS (tire pressure warning system) to continue to function
properly.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specifications or makers, as the tire pressure warning
system may not operate properly.

When replacing tires on a vehicle with wheel lock nuts, use the following proce-
dures to remove and install the wheel lock nuts. The wheel lock key is stored in
the tray inside the luggage compartment. Always return the wheel lock key to its
original position after use, so that it does not get lost.
■Removal
For ease of removal, the wheel lock nut should always be the first one loos-
ened.
Place the wheel lock key on top of the wheel lock nut, turning until the wheel
lock key and wheel lock nut patterns engage.
Place the wheel nut wrench on the wheel lock key, and while applying pres-
sure on the wheel lock key, loosen the wheel lock nut.
■Installation
For ease of installation, the wheel lock nut should always be the last one tight-
ened.
By hand, install a wheel lock nut on each wheel.
Place the wheel lock key on top of the wheel lock nut, turning until the wheel
lock key and wheel lock nut patterns engage.
Place the wheel nut wrench on the wheel lock key, and while applying pres-
sure on the wheel lock key, tighten the wheel lock nut to the recommended
torque.
Wheel lock nut (if equipped)
NOTICE
Do not use an impact wrench. Using an impact wrench may cause permanent damage
to wheel lock nut and wheel lock key. If in doubt about wheel lock application, contact
your Lexus dealer.
