Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■TRC (Traction Control)
Helps to maintain drive power and pr event the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads.
The TRC system is also equipped with the brake LSD function.
■ Hill-start assist control
→
P. 253
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■Emergency brake signal
When the brakes are applied suddenly, the emergency flashers auto-
matically flash quickly to alert the vehicle behind.

■ Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
systems
●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 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 malfunction.

Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
●Vehicles without a smart entry & start system: When the engine switch is
turned to “LOCK” position
● Vehicles with a smart entry & start system: When the “ENGINE START
STOP” switch is turned off
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed is more than approximately 50 km/h (31 mph).
If both the TRC and VSC systems are turned off, automatic reactivation
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 steer ing 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 normal after a little while.
■ Automatic deactivation of “TRACK” mode
Vehicles without a smart entry & start system
When the engine switch is turned to “LOCK” position after driving in
“TRACK” mode, the mode is automatically deactivated.
Vehicles with a smart entry & start system
When the “ENGINE START STOP” switch is turned off after driving in
“TRACK” mode, the mode is automatically deactivated.
■ Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal
will operate:
●The emergency flashers are off.
● Actual vehicle speed is over 60 km/h (38 mph).
● The brake pedal is depressed in a manner that cause the system to
judge from the vehicle deceleration that this is a sudden braking opera-
tion.

Hill-star t assist control
Hill-start assist control helps to maintain braking force to assist
starting off forward while facing uphill or starting off backward while
facing downhill. As hill-start assist control is initially disabled,
enable the system to make it oper able. The enabled/disabled setting
will be maintained the next time the engine is started.
The hill-start assist control ON
indicator will be illuminated
when system is enabled and
flash while the system is oper-
ating.
■ Enabling hill-start assist control
Park your vehicle in a flat, safe location.
Make sure that the parking brake is securely engaged.
Stop the engine by turning the engine switch to the “LOCK”
position (vehicles without a smart entry & start system) or
turning the “ENGINE START STOP” switch off (vehicles
with a smart entry & start system).
Start the engine and check that the ABS warning light and
slip indicator are off.
Press and hold for
approximately 30 seconds.
Check that both the VSC off
indicator and “TRC OFF” indi-
cator illuminate and then turn
off.

Ventilation and air conditioning odors
●To let fresh air in, set the air condi tioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditi oning 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.
■ Air conditioning filter
→ P. 357
WARNING
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
