this case, immediately stop the vehicle in a safe place, and check the engine after
it has cooled completely. ( P. 5 0 1 )

CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on
when you start the engine, this could mean that these systems are not available to
help protect you in an accident, which could result in death or serious injury. Have
the vehicle inspected by your Lexus dealer immediately if this occurs.
*1: These lights turn on when the “ENGINE START STOP” switch is turned to IGNITION ON mode to indicate that a system check is
being performed. They will turn off after the engine is started, or after a
few seconds. There may be a malfunction in a system if a light does not
come on, or if the lights do not turn off. Have the vehicle inspected by
your Lexus dealer.
*2: The light flashes to indicate that the system is operating.
■ Warning lights
Warning lights inform the driver of malfunctions in any of the vehi-
cle’s systems. ( P. 4 6 1 )

■Driving range
■ Average fuel consumption
■ Average fuel consumption after refueling
■ Current fuel consumption
■ Average vehicle speed Displays the estimated maximum distance that can
be driven with the quantity of fuel remaining.
• This distance is computed based on your average fuel
consumption. As a result, the actual distance that can
be driven may differ from that displayed.
• When only a small amount of fuel is added to the tank, the display may not be updated.
Displays the average fuel consumption since the
function was reset.
The function can be reset by pushing the “DISP” switch
for longer than one second when the average fuel con-
sumption is displayed.
Displays the average fuel consumption since the
vehicle was last refueled.
Displays the current rate of fuel consumption.
Displays the average vehicle speed since the engine
was started or the function was reset.

When driving
■Gear position display
(vehicles with an automatic transmission only)
Indicates the current gear , and the range of gears
that is available when the shift lever is in the D or S
position. The gear range is shown by the number of
dots ( ) and the current gear is shown as a number.
The transmission automatically selects the gears
within the driver selected gear range.
In the illustration to the left , a range of 6 available gears
(1 through 6) has been selected by the driver. (The shift
lever is in the D or S position with 6 ranges enabled.) It is
possible for the transmission to automatically select
between all 6 of the gears. In this case, the transmission
has selected third gear.
■System check display
After switching the “ENGINE START ST OP” switch to IGNITION ON mode,
“CHECK” is displayed while system operation is checked. When the system check
is complete, “COMPLETED” is displayed before returning to the normal screen.
■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 12 mph [20 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)

CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver's shifting and the new gear number
appearing on the display. This lag could cause the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in personal
death or injury.
