●The temperature display shows temperatures within the range of -40F (-40C)
and 122 F (50C).
●In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
• When the vehicle is stopped, or moving at low speeds (less than 15 mph [25
km/h])
• When the outside temperature has chan ged suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●When “--” or “E” is displayed, the system may be malfunctioning. Take your vehi-
cle to your Lexus dealer.
NOTICE
■To prevent damage to the engine and its components

When driving
■Tire grip at low temperatures
The tires fitted to the LFA are designed for dry road conditions. As such, tire grip on
cold, snowy and/or icy roads will be reduced compared to standard tires.
Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed
appropriate for road and weather conditions.
■Engine starting restrictions
In order to protect the engine, the engine may not start when the engine coolant
temperature or engine oil temperature is below -13 F (-25C). In that case, a
buzzer will sound and “Temp low Engine cannot be started” will be shown on the
meter. ( P. 3 2 7 )
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or serious
injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires
being used.
●Use snow tires on all, not just some wheels.
NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may da mage the vehicle body and suspension, and
adversely affect driving performance.
■Repairing or replacing snow tires
Request repairs or replacement of snow ti res from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.

CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident, causing death or serious injury.
■Wheel bolts
Observe the following precautions to reduce the risk of death or serious injury:
●Do not over tighten.
●Never use oil or grease on the wheel bolts.
Oil and grease may cause the wheel bolts to be excessively tightened, leading to
bolt or disc wheel damage. In addition, the oil or grease can cause the wheel bolts
to loosen and the wheel may fall off, causing a serious accident. Remove any oil or
grease from the wheel bolts.
●If there are any cracks or deformations in the wheel bolts, or if the surface treat-
ment becomes worn, have the wheel bolts replaced at your Lexus dealer.
Failure to follow these precautions could cause the wheel bolts to loosen and the
tire to fall off, resulting in death or serious injury.
●If the wheels are frequently removed and installed due to circuit driving etc.,
Lexus recommends periodic changing of the wheel bolts.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Lexus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitters at your Lexus dealer.
●Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-
genuine wheels.

5-2. Steps to take in an emergency
NOTICE
■Vehicles with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel
beyond repair.
■When performing an emergency repair
Perform the emergency repair without removing the nail or screw that has punc-
tured the tread of the tire. If the object th at has punctured the tire is removed, the
repair using the sealant in the emergenc y tire puncture repair kit may fail.
■When fixing the flat tire
●Do not put the valve core on dirty ground or in the sand.
Store it in a clean place.
●Do not remove the inside cap of the sealant bottle.
●Turn the valve core tool with your hand when screwing it in. If you use another tool
in conjunction with the valve core tool, damage may occur.
●Do not operate the compressor continuously for more than 10 minutes. The
motor may overheat and be damaged. Le t the compressor cool before using it
again.
■Compressor precautions
●The compressor power source should be 12 V DC suitable for vehicle use.
Do not connect the compressor to 24 V DC or any other power source.
●The compressor is an oil-less type. Do not lubricate with oil.
●If the compressor does not operate properly or becomes hot, it may be over-
heated. Turn off the switch and leave the compressor to cool down for at least 30
minutes.
●The compressor is not waterproof. Make sure that the compressor is not exposed
to water, such as when it is being used in the rain.
●Do not put the compressor directly onto dusty ground such as sand at the side of
the road. If the compressor vacuums up dust etc., a malfunction may occur.
●Do not disassemble or modify the compre ssor. Do not subject parts such as the
air pressure indicator to impacts. This may cause a malfunction.
