the fuel consumption (MPG, km/l,
L/100km) measurement units will
be changed.
■ “Temp” (temperature)
The units of measurement used fo r the outside temperature, engine
coolant temperature, engine oil temperature and air conditioning tem-
perature displays can be changed.

When driving
■Using the “Lap Timer”
●When the “Lap Timer” function is turned “OFF” or the engine is stopped while a
lap is being timed, the lap timer will stop and the lap time up to that point will be
recorded.
●If the lap time being recorded ends with the same time as the fastest lap, the
newer time will be saved as the fastest lap time.
●If the lap time exceeds “9:59:59.99”, the display will return to “0:00:00.00” but
the total time will be recorded.
●If a warning message is displayed when a lap time is being measured, the lap
time will still continue to be recorded.
Operating the control pad while the warning message is shown returns the dis-
play to the stopwatch but the warning message will continue to appear until the
warning is resolved.
●In the normal display, the current measurement time and the latest lap time will
be displayed.
■Changing the temperature measurement unit
When the “Temp” measurement unit is ch anged, the air conditioning system tem-
perature setting, air outlet s and fan speed characteristic s may be changed. This is
normal and does not indicate a malfunction.
■If the battery is disconnected or discharges
“Lap Timer” data and “Clock” settings will be reset.

2-5. Driving information
Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the pre-
vailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine coolant
• Washer fluid
● Have the vehicle fitted with four snow tires.
Ensure that all tires are the specified size and the same brand.
■Before driving the vehicle
Perform the following according to the driving conditions.
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in front
of the windshield.
● Remove any ice that has accumu lated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow that may
have accumulated in the wheel well or on the brakes.
■ When driving the vehicle
Accelerate the vehicle slowly and driv e at a reduced speed suitable to
road conditions.

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 (-25C). 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.
