Tachometer
The Tachometer indicates the engine
Revolutions Per Minute (Giri).
Adjusting Instrument Panel Lighting
(Brightness Sensor)
Inside the Tachometer there is a light
sensor capable of detecting light and
adjusting the brightness of the
instrument panel and the Information
and Entertainment System display.
Engine Oil Temperature Gauge
The digital indicator monitors the
temperature of the engine oil and starts
supplying indications when the oil
temperature reaches approximately
122° F (50°C).
Under normal usage, the temperature
should remain around the middle of the
digital scale according to the working
conditions.
The
warning light will turn on to signal
the excessive increase of the engine oil
temperature.
In the event of excessive engine oil
temperature, stop the engine
immediately and contact an authorized
dealer.
Fuel Level Gauge
The digital fuel gauge monitors the
amount of fuel in the tank.
When the
warning light turns on, a
message is displayed, and a chime is
sound when 2.38 Gallons (9.0 L) of fuel
are left in the tank.

Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or
tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low tire
pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or
signal low tire pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly. Always check the TPMS
malfunction telltale after replacing one
or more tires or wheels on your vehicle, to
ensure that the replacement or alternate
tires and wheels allow the TPMS to
continue to function properly.
Caution!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system operation
or sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealership to have your sensor function
checked.
