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.

Engine coolantThe coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
“FULL”

■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life
hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized
water. (Minimum temperature: -31 F [-35C])
For more details about coolant, contact your Lexus dealer.
■If the coolant level drops within a short time of replenishing
Visually check the hoses and engine coolant reservoir cap.
If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in
the cooling system.

Maintenance and care
CondenserCheck the condenser and clear any foreign objects.
If it is extremely dirty or you are not sure of its condition, have your vehicle
checked by your Lexus dealer.
CAUTION
■When the engine is hot
Do not remove the engine coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing burns or other injuries.
NOTICE
■When adding engine coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of water
and antifreeze must be used to provide proper lubrication, corrosion protection
and cooling. Be sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
CAUTION
■When the engine is hot
Do not touch the condenser, as it may be hot and cause burns.
