2-4. Using other driving systems
CAUTION
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level. ( P. 366)
The ABS, VSC and TRAC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further info rmation when replacing tires or wheels.

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.
