WARNING
■When the Stop & Start system is operating
Make sure to disable the Stop & Start system while the vehicle is in a poorly ventilated area.
If not disabled, the engine may be automatically restarted unexpectedly, causing exhaust gases to collect and
enter the vehicle, possibly resulting in death or a serious health hazard.
●Do not leave the vehicle while the
engine is stopped by the Stop & Start system (while the Stop & Start indicator is on). An accident may
occur due to the automatic engine start function.

wet with standing water during bad
weather, such as heavy rain, snow, or
fog
• When multiple vehicles are approach-
ing with only a small gap between
each vehicle
• When the distance between your vehi-
cle and a following vehicle is short
• When there is a significant difference
in speed between your vehicle and
the vehicle that enters the detection
area
• When the difference in speed
between your vehicle and another
vehicle is changing
• When a vehicle enters a detection
area traveling at about the same
speed as your vehicle

■Operating conditions of hill-start
assist control
When the following four conditions are
met, the hill-start assist control will oper-
ate:
●The shift lever is in a position other
than R when starting off forward on an
upward incline, or the shift lever is in
R when starting off backward on an
upward incline.
●The vehicle is stopped
●The accelerator pedal is not
depressed
●The parking brake is not engaged
●Engine switch is turned to ON
■Automatic system cancelation of
hill-start assist control
The hill-start assist control will turn off in
any of the following situations:
●The shift lever is shifted to R when
starting off forward on an upward
incline, or the shift lever is shifted to
other than R when starting off back-
ward on an upward incline.
●The accelerator pedal is depressed
●The parking brake is engaged
●2 seconds at maximum elapsed after
the brake pedal is released
●Engine switch is turned to OFF
■Sounds and vibrations caused by
the ABS, brake assist, VSC, TRC
and hill-start assist control sys-
tems
●A sound may be heard from the
engine compartment when the brake
pedal is depressed repeatedly, when
the engine is started or just after the
vehicle begins to move. This sound
does not indicate that a malfunction
has occurred in any of these systems.
●Any of the following conditions may
occur when the above systems are
operating. None of these indicates
that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also
after the vehicle comes to a stop.
• The brake pedal may pulsate slightly
after the ABS is activated.
• The brake pedal may move down
slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunc-
tion.
■Automatic reactivation of TRC and
VSC systems
After turning the TRC and VSC systems
off, the systems will be automatically re-
enabled in the following situations:
●When the engine switch is turned off
●If only the TRC system is turned off,
the TRC will turn on when vehicle
speed increases.
If both the TRC and VSC systems are
turned off, automatic re-enabling will
not occur when vehicle speed
increases.
■Reduced effectiveness of the EPS
system
The effectiveness of the EPS system is
reduced to prevent the system from
overheating when there is frequent
steering input over an extended period
of time. The steering wheel may feel
heavy as a result. Should this occur,
refrain from excessive steering input or
stop the vehicle and turn the engine off.
The EPS system should return to nor-
mal within 10 minutes.
■Operating conditions of emergency
brake signal
When the following conditions are met,
the emergency brake signal will oper-
ates:
●The emergency flashers are off
●Actual vehicle speed is over 55 km/h

■The ABS does not operate effec- tively when
●The limits of tire gripping perfor-mance have been exceeded (such as excessively worn tires on a snow
covered road).
●The vehicle hydroplanes while driv-
ing at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a safe distance from
the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with pot-holes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not
be achievable while driving on slip- pery road surfaces, even if the TRC/VSC system is operating. Drive
the vehicle carefully in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may not operate effectively on steep

• It is recommended that the air condi-
tioning system be set to outside air mode prior to turning the vehicle off.• The start timing of the blower may be
delayed for a short period of time immediately after the air conditioning system is started in automatic mode.
●When parking, the system automati-cally switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce odors that occur when starting
the vehicle.

1Press the automatic mode
switch.
2 Adjust the temperature setting.
3 To stop the operation, press the
off switch.
If the fan speed setting or air flow
modes are operated, the automatic
mode indicator goes off. However,
automatic mode for functions other
than that operated is maintained.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately after the automatic mode
switch pressed.
To turn on the “DUAL” mode, per-
form any of the following proce-
dures:
z Press the “DUAL” switch.
z Adjust the front passenger’s side
temperature setting.
The indicator on the “DUAL” switch
comes on when the “DUAL” mode is
on.
Pressing the “DUAL” switch when in
“DUAL” mode will disable “DUAL”
mode, and the temperature setting for
the front passenger’s side will become
linked to the driver’s side.
WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger switch during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause the outer surface of the
windshield to fog up, blocking your vision.
■When the outside rear view mir-ror defoggers are operating
Do not touch the outside rear view
mirror surfaces, as they can become very hot and burn you.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning sys-
tem on longer than necessary when the engine is off.
