lower than the gear in use during normal D position driving.
nAutomatic deactivated of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
lWhen the vehicle comes to a stop
lWhen range 6 is selected and the accelerator pedal is depressed
lIf the accelerator pedal is depressed for more than a certain period of time
nGear position display when driving
The current gear is displayed on the multi-information display. (→P. 1 5 4 )
nDownshifting restrictions warning buzzer
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or shift paddle switch is operated. (The warning buzzer will
sound twice.)
nWhen driving with the cruise control system or dynamic radar cruise control sys-
tem

NOTICE
nTo prevent damage to the engine and its components
lDo not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.

CAUTION
nIf 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.
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the engine is started, or after a few sec-
onds. 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.

nGear 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.
nSystem check display
After switching the “ENGINE START STOP” 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.
nOutside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
lWhen stopped, or driving at low speeds (less than 12 mph [20 km/h])
lWhen the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)

CAUTION
nThe 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 possibly an accident resulting in personal
death or injury.
