(engine running) mode.
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.

Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.

When trouble arises

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.

GS350/250_EE (OM30C36E)
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.
