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.

NOTICE
Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
and wheel beyond repair.

1. Get the tool, jack, wrench, adapter socket (for
removing a spare tire) and spare tire.
To prepare yourself for an emergency, you should
familiarize yourself with the use of the jack and each
tool, and their storage locations.

IN CASE OF AN EMERGENCY
505
To remove the spare tire:
1Remove the inside spare tire cover by turning it
counterclockwise.
If it is difficult to remove the inside spare tire cover,
remove the cover after pulling out the spare tire and
stand it up against the bumper.
2In the luggage compartment, open the right side
auxiliary box by pushing the button. You will find
the spare tire clamp bolt on the right side of the
auxiliary box.
3Remove the cover using a flathead screwdriver
which is wrapped with a cloth.

IN CASE OF AN EMERGENCY
506
4Put the adapter socket (for removing a spare tire)
on the spare tire clamp bolt.
5Connect the jack handle and the adapter socket.
Turn the jack handle counterclockwise. The tire
will lower completely to the ground.
6Pull out the spare tire and stand it up against the
bumper.
7Remove the holding bracket.

IN CASE OF AN EMERGENCY
509
5. After making sure no one is in the vehicle, raise
it high enough so that the spare tire can be
installed.
Allow for the fact that you need more ground
clearance when putting on the spare tire than when
removing the flat tire.
To raise the vehicle, insert the jack handle into the
jack (it is a loose fit) and turn it clockwise. As the
jack touches the vehicle and begins to lift,
double−check that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle
is supported by the jack alone.

9. After changing the wheel, check the air pressure
of the replaced tire.
If the pressure of the replaced tire is low, drive slowly
to the nearest service station and fill to the correct
pressure.
Do not forget to reinstall the tire valve cap as dirt and
moisture could get into the valve core and possibly
cause air leakage. If the cap is missing, put a new
one on as soon as possible.10. Stow all the tools, jack and flat tire securely.
To stow the flat tire, install the inside spare tire cover
on the outer side of the spare tire cover. Put the flat
tire in the spare tire cover with the outer side facing
up and install the holding bracket. Turn the spare
tire clamp bolt clockwise with a jack handle and
adapter socket until you hear a click.
NOTICE
Ensure that there is no object caught between
the tire and the vehicle underbody.
Otherwise, the wheel may fly forward during
a collision or sudden braking.
 Tighten the spare tire clamp bolt to hold the
spare wheel carrier by the hook securely.
This is the same procedure for changing or rotating
your tires.

The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on pages 566 and 616. They are also described
on the tire and loading information label as
shown.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!
The following instructions for checking tire
inflation pressure should be observed:
The pressure should be checked only when the
tires are cold. If your vehicle has been parked
for at least 3 hours and has not been driven for
more than 1.5 km or 1 mile since, you will get an
accurate cold tire inflation pressure reading.
 Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.
 Do not bleed or reduce tire inflation pressure
after driving. It is normal for the tire inflation
pressure to be higher after driving. 
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located
so that the vehicle is balanced.
Inspection and adjustment procedure
1Tire valve
2Tire pressure gauge
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire
valve.
3. Read the pressure using the graduations of the
gauge.

This applies also to the spare tire and tires stored
for future use.
Tire selection
When replacing a tire, use a tire of the same size
and construction, and the same or greater
maximum load as the originally installed tires.
Also, on fourwheel drive models, all the tires
must be the same brand and have the same tread
patterns.
Using any other size or type of tire may seriously
affect handling, ride, speedometer/odometer
calibration, ground clearance, and clearance between
the body and tires or snow chains.
Check that the maximum load of the replaced tire is
greater than 1/2 of the Gross Axle Weight Ratings
(GAWR) of either the front axle or the rear axle,
whichever is greater. As for the maximum load of
the tire, see the load limit at maximum cold tire
inflation pressure mentioned on the sidewall of the tire,
and as for the Gross Axle Weight Ratings (GAWR),
see the Certification Label. For details about
Certification Label and sidewall of the tire, see pages
536 and 573.
CAUTION
Observe the following instructions. Otherwise,
an accident may occur resulting in death or
serious injuries.
Do not mix radial, bias belted, or biasply tires
on your vehicle, as this may cause dangerous
handling characteristics resulting in loss of
control.
 Do not use tires other than the manufacturer’s
recommended size, as this may cause
dangerous handling characteristics resulting
in loss of control.
 Fourwheel drive models:
Do not use tires of different brands, sizes,
construction or tread patterns, as this may
cause dangerous handling characteristics
resulting in loss of control.
