■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.

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

Measurement resultOnce measurement is complete,
the result will be displayed.
The oil amount between the maxi-
mum and minimum markings is
approximately 2.1 qt. (2.0 L, 1.8
Imp. qt.).
As the engine oil level in the oil
tank varies depending on the driv-
ing condition of the vehicle imme-
diately before measurement, the
results may vary even if the overall
oil amount is constant.
Perform the following actions as necessary according to the measure-
ment results:
● If the oil level is low, add engine oil as needed. ( P. 257)
Even if the measurement result shows th at the engine oil is below the maxi-
mum level, be careful not to add more oil than necessary. If unsure of how
much oil to add, contact your Lexus dealer.
● If “Engine oil level low Check oil le vel” is displayed on the meter, avoid
high load driving and add oil immediately.
Do not let the oil level reach or fall below the minimum marking, as doing so
may cause engine damage.
