2-1. Driving procedures
■If the engine does not start
●Repeat the procedure again. If the engine does not start after a few tries, the
“ENGINE START” switch may be malfunctioning. Have the vehicle inspected
by your Lexus dealer.
●Check to make sure that the brake pedal is firmly depressed and that “N” is dis-
played in the gear indicator. (If the brake pedal is not depressed or “N” is not
displayed, the engine will not start.)
●The engine immobilizer system may not have been deactivated. ( P. 5 3 )
●In order to protect the engine, the engine may not start when the engine coolant
temperature or the 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 )
■When the steering lock cannot be released
■Key reminder function
A buzzer sounds if the driver’s door is opened while the ignition switch is in the
“LOCK” or “ACC” position to remind you to remove the key.
■After reconnecting the battery
If the gear indicator is not displayed when an attempt is made to start the engine,
the engine is not yet ready to start. Depr ess the brake pedal for several seconds and
wait for the gear indicator to appear.
When starting the engine, the ignition switch
may seem stuck in the “LOCK” position. To
free it, turn the key while turning the steering
wheel slightly left and right.

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.
