■Tire inflation pressure (if equipped)
Outside temperature, average fuel
consumption after re fueling or driv-
ing range can be selected and dis-
played.
If displayed on the drive monitor,
other trip information or warning
messages can be di splayed simulta-
neously.
For display and selection proce-
dures, follow the “Setting up the dis-
plays”.
The information displayed on the drive

■Tire inflation pressure (if equipped)
●It may take a few minutes to display the tire inflation pressure after the engine
switch is turned to IGNITION ON mode. It may also take a few minutes to display
the tire inflation pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavor-
able radio wave conditions.
●Tire inflation pressure changes with temperature. The displayed values may also be
different from the values measured using a tire pressure gauge.
■Liquid crystal display
Small spots or light spots may appear on th e display. This phenomenon is character-
istic of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
Setting of available languages can be changed. (Custo mizable features P. 777)
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 dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
■Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that the
vehicle is parked in a place with adequate ventilation. In a closed area such as a
garage, exhaust gases including harmful carbon monoxide (CO) may collect and
enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
■During setting up the display
To prevent battery discharge, ensure that the engine is running while setting up the
display features.

Driving
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving,
as this may restrain driving torque.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at
the same time to hold the vehicle on a hill.
■When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to move or
the vehicle may accelerate suddenly if the accelerator pedal is accidentally
depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage th e power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.

4-5. Using the driving support systems
■If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure warning
will not operate for the side on which lane markers could not be recognized.
■Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it may not
be possible to ensure adequate performance. Also, the camera sensor may be
unable to recognize lane lines causing the lane departure warning function to oper-
ate incorrectly, or the lane keeping assist function may not operate properly. How-
ever, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing
or before a ticket checkpoint
●When driving on a sharp curve
●When lanes are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is
extremely short
●When the lane markers are yellow (These may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Botts’ dots”, “Raised pavement marker” or
stones
●When lane markers are obscured or pa rtially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
●When driving on a particularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
●When sunlight or the headlights of oncoming vehicles are shining directly into the
camera lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet due to rain, previous rainfall, standing
water, etc.
●When the vehicle experiences strong up-a nd-down motion such as when driving
on an extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or
when the headlights are misaligned
●When driving with a strong crosswind
