STARTING AND DRIVING
463
Low tire pressure warning light
This light comes on when the ignition key is turned to the “ON”
position. It goes off after a few seconds. This indicates that the
tire pressure warning system is functioning properly.
If the low tire pressure warning light comes on or blinks
while driving, do the following.
 If the warning light comes on: The tire pressure is critically
low. Adjust the tire inflation pressure to the specified level
as soon as possible. (See “Tires and wheels” on page 566.)
Once the ignition switch is turned off, the warning light also
goes off. If the light comes on again when the vehicle is started
after adjusting tire inflation pressure to the specified level, have
the system checked at your Lexus dealer. If you have a flat tire, replace it with the spare tire. For details,
see “If you have a flat tire” on page 500.

If the warning light blinks once every second: The low
tire pressure warning system may be malfunctioning.
Contact your Lexus dealer.
 If the warning light blinks twice every second: The low
tire pressure warning system needs to be initialized. Reset
the system with the tire pressure warning system reset
switch. (To reset the system, see “Tire pressure warning
system reset switch”.)
The tire pressure warning system does not function
properly under certain circumstances. In the following
cases, the low tire pressure warning light may not come
on even if the tire inflation pressure is low, or it may come
on when the tire inflation pressure is actually normal.
 A compact spare tire, snow tires, or tire chains are used.
 The tire inflation pressure is excessively higher than
specified, or tire inflation pressure suddenly drops due to
bursting or other causes.
 The vehicle is driven on a slippery road surface such as
rough or frozen roads.
 The vehicle speed is less than 30 km/h (19 mph) or more
than 100 km/h (62 mph), and the driving duration is less than
5 minutes.
 The tires differ in tread pattern or manufacturer.
 The tires are not the specified size.

STARTING AND DRIVING
464
The tread wear is very different among the installed tires.
 Rapid acceleration/deceleration or sharp turns is continue.
 Towing a trailer.
 The loading is over the limit or imbalanced.
 Initialization was not performed correctly after replacing or
rotating tires or wheels.
 The outside temperature is below 0 C (32F) or above
40 C (104 F).
CAUTION
When the tire pressure warning light comes on, observe
the following instructions:
 Adjust the tire inflation pressure to the specified level
as soon as possible.
 Avoid abrupt steering wheel maneuvering and
braking when the tire pressure warning light comes
on. If the vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes, causing
death or serious injury.
Tire pressure warning system reset switch
The tire pressure warning system need to be initialized in
the following conditions:
When the low tire pressure warning light blinks twice
every second
 After replacing or rotating tires or wheels
When initializing the system, the present tire condition is
stored as a standard.
To initialize the system, perform the following:
1. Park the vehicle at a safe place and apply the parking brake.
Stop the engine.
2. Adjust the pressure of all the installed tires to the specified
level. (See “Tires and wheels” on page 566.)
3. Turn the ignition key to “ON”.

STARTING AND DRIVING
465
4. With the vehicle stopped, push the reset switch on the left
lower instrument panel and hold it until the low tire pressure
warning light blinks three times.
Initialization is
completed after driving at the speeds of 30 km/h
(19 mph) or over for about a few hours total, when the tire
pressure warning system detects the normal tire pressure. If
the following driving conditions are satisfied, initialization will
be completed in about one hour.
 Vehicle speed varies between 30 km/h (19 mph) and 80
km/h (50 mph)
 Normal road surface
When the warning light blinks twice every second while driving,
you may be unable to reset the system. In this case, set the
system again according to the above procedure.
Do not push the reset switch without adjusting the tire inflation
pressure to the specified level. Otherwise, the low tire
pressure warning light may not come on even if the tire
pressure is low, or it may come on when the tire inflation
pressure is actually normal.
If you push the reset switch while the vehicle is moving,
initialization is not performed.
If the low tire pressure warning light does not blink when you
push and hold the reset switch, have the low pressure warning
system checked at your Lexus dealer.
BRAKE PAD WEAR LIMIT INDICATORS
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have the
brake pads checked and replaced by your Lexus dealer as
soon as possible. Expensive rotor damage can result if the
pads are not replaced when needed.
