■Gear position display
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 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.

Intuitive parking assist
The distance to obstacles measured by the sensors is communicated via
the multi-information display and a buzzer when parallel parking or
maneuvering into a garage. Always check the surrounding area when
using this system.

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
In addition to the examples above, there are instances in which, because of their
shapes, signs and other object s may be judged by the sensor to be closer than they
are.
●The shape of the obstacle may prevent th e sensor from detecting it. Pay particu-
lar attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle

speed increases.
■Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on even when
vehicle speed increases.
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and hill-start
assist control systems
●A sound may be heard from the engine compartment if the brake pedal is
depressed repeatedly when the engine is started or just after the vehicle begins
to move. This sound does not indicate th at a malfunction has occurred in any of
these systems.
●Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
