When refueling, turn the “ENGINE START STOP”
switch off. If the vehicle is refueled without turning

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 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.
■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])

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 downshifting and the new gear
number appearing on the display. In this case, wait until the display changes and
take care not to downshift again, causing rapid and excessive engine braking and
possibly an accident resulting in death or serious injury.

Turning on the high beam headlightsWith the headlights on, push the
lever forward to turn on the high
beams.
Pull the lever back to the center
position to turn the high beams off.

■Daytime running light system
●Vehicles with halogen headlights: to make your vehicle more visible to other
drivers, the headlights turn on automatically (at a reduced intensity) whenever
the engine is started and the parking brake is released. Daytime running lights
are not designed for use at night.
Vehicles with discharge headlights: to make your vehicle more visible to other
drivers, the parking lights turn on automatically (at a increased intensity) when-
ever the engine is started and the parking brake is released. Daytime running
lights are not designed for use at night.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
■Headlight control sensorThe sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

off once and then back to or

■Automatic headlight leveling system (vehicles with discharge headlights)
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere with other road users.

Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features →P. 553)
