Bluetooth
®Audio (if

device is plugged into the system,
you can also select AUX.
If you are listening to the radio, use
the CH button to change stations.
Each time you press the top (＋ )of
the button, the system goes to the
next preset station on the band you
are listening to. Press the bottom
(－ ) to go back to the previous preset
station. If you press and hold the CH
button (＋ )or(－), the system goes

skips to the beginning of the next
track/file (file in MP3, WMA, or AAC
format) each time you press the top
(＋ ) of the CH button. Press the

Your vehicle's audio system may
disable itself if it is disconnected
from electrical power for any reason.
To make it work again, you must
enter a specific five-digit code with
the preset buttons. Because there are
hundreds of number combinations
possible from the five digits, making
the system work without knowing
the exact code is nearly impossible.
You should have received a card that
lists your audio system code number
and serial number. It is best to store
this card in a safe place at home. In
addition, you should write the audio
system's serial number in this
owner's manual.
If you lose the card, you must obtain
the code number from your dealer.
To do this, you will need the audio
system's serial number.If your vehicle's battery is
disconnected or goes dead, the audio
system will disable itself. If this
happens, you will see
‘‘
’’in
the audio display the next time you
turn on the system. Use the preset
buttons to enter the five-digit code.
The code is located on the radio code
card included in your owner's
manual kit. When it is entered
correctly, the radio will start playing.
If you make a mistake entering the
code, do not start over; complete the
five-digit sequence, then enter the
correct code. You have 10 tries to
enter the correct code. If you are
unsuccessful in 10 attempts, you
must then leave the system on for 1
hour before trying again. The system will retain your AM and
FM presets even if power is
disconnected.

Minimize the use of the air
conditioning system－The A/C
puts an extra load on the engine
which makes it use more fuel. Use
the fresh-air ventilation when
possible.
●
Plan and combine trips －
Combine several short trips into
one. A warmed-up engine is more
fuel efficient than a cold one.
Calculating Fuel Economy
Measuring TechniquesDirect calculation is the
recommended source of information
about your actual fuel economy.
Using frequency of fill-ups or taking
fuel gauge readings are NOT
accurate measures of fuel economy.
Fuel economy may improve over the
first several thousand miles
(kilometers).
Checking Your Fuel Economy1)Fill the fuel tank until the nozzle automatically clicks off.
2)Reset trip counter to zero.
3)Record the total gallons (liters) needed to refill.
4)Follow one of the simple calculations above.

To see the inflation pressures of all
four tires, press the SEL/RESET
button. The display changes as
shown above.
Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the sensor
in that tire immediately sends a
signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
U.S. model

This shows that front left tire
is losing pressure.

‘‘SYSTEM FUNCTION ERROR ’’
message and the tire pressure
readings are not displayed. If this
happens, you will first see a system
warning message ‘‘CHECK TPMS

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surfaces. It does this by
regulating the engine's output and by
selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise from the VSA
hydraulic system. You will also see
the VSA system indicator blink.
The VSA system cannot enhance the
vehicle's driving stability in all
situations and does not control your
vehicle's entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
VSA Off Indicator
When VSA is off, the VSA off
indicator comes on as reminder.Vehicle Stability Assist
(VSA) System Indicator
When VSA activates, you will see the
VSA system indicator blink.
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
NOTE: The main function of the VSA
system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control function. If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
