The compact spare tire
The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
Make sure to check the tire inflation pressure of the compact spare tire.
(P. 850)
When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning valve
and transmitter, low inflation pressure of the spare tire will not be indicated
by the tire pressure warning system. Also, if you replace the compact spare
tire after the tire pressure warning light comes on, the light remains on.
When the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire com-
pared to when driving with standard tires.
If you have a flat rear tire on a road covered with snow or ice (vehicles with
front and rear tires of the same size and compact spare tire only)
Install the compact spare tire on one of the front wheels of the vehicle. Per-
form the following steps and fit tire chains to the rear tires:
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires.

CAUTION
Speed limit when using the compact spare tire
Do not drive at speeds in excess of 80 km/h (50 mph) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failure to
observe this precaution may lead to an accident causing death or serious
injury.
After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in
their storage location to reduce the possibility of personal injury during a
collision or sudden braking.
NOTICE
Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving per-
formance.
When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional as the tire pressure warn-
ing valve and transmitter may be damaged if not handled correctly.

CAUTION
When fixing the flat tire
Stop your vehicle in a safe and flat area.
Connect the valve and hose securely with the tire installed on the vehicle.
If the hose is not properly connected to the valve, air leakage may occur or
sealant may be sprayed out.
If the hose comes off the valve while inflating the tire, there is a risk that
the hose will move abruptly due to air pressure.
After inflation of the tire has completed, the sealant may splatter when the
hose is disconnected or some air is let out of the tire.
Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off the compressor switch and stop
the repair operation immediately.
The kit may overheat if operated for a long period of time. Do not operate
the compressor continuously for more than 10 minutes.
Parts of the kit become hot during operation. Be careful handling the kit
during and after operation.
Do not attach the vehicle speed warning sticker to an area other than the
one indicated. If the sticker is attached to an area where an SRS airbag is
located, such as the pad of the steering wheel, it may prevent the SRS air
bag from operating properly.
Driving to spread the liquid sealant evenly
Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
If the vehicle does not drive straight or you feel a pull through the steering
wheel, stop the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm
2
or bar, 19 psi) or below, this may indicate severe tire damage.
