iQ_WE_74014E
Vehicles without smart entry & start system:
If the wiper switch is turned to AUTO position while the engine switch is in
the ON position, the wiper will operate once to show that AUTO mode is
activated.
Vehicles with smart entry & start system:
If the wiper switch is turned to AUTO position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wiper will operate once to
show that AUTO mode is activated.
If the temperature of the raindrop sensor is 90°C (194°F) or higher, or
-10°C (14°F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked and that there is washer fluid
in the windshield washer fluid reservoir.
CAUTION
Caution regarding the use of windshield wipers in AUTO mode
(vehicles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers or anything else does not become caught in the windshield wipers.
NOTICE
When the windshield is dry
Do not use the wipers, as they may damage the windshield.
When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
When a nozzle becomes blocked
Do not try to clear it with a pin or other object. The nozzle will be damaged.

2-4. Using other driving systems
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.
VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
TRC (Traction Control)
Maintains drive power and prevents the front wheels from spinning
when starting the vehicle or accelerating on slippery roads.
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

226 2-4. Using other driving systems
iQ_WE_74014E
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 smart entry & start system
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 reactivation
will not occur when vehicle speed increases.
Vehicles with 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 increases
If both the TRC and VSC systems are turned off, automatic reactivation
will not occur when vehicle speed increases.
Sounds and vibrations caused by the ABS, VSC, TRC and brake assist
systems
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate 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.

Interior features
iQ_WE_74014E
When outside air temperature approaches 0C (32F)
The air conditioning system may not operate even when is pressed.
When
is selected for the air outlets used
For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the position of the temperature adjust-
ment dial.
Air conditioning odors
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 conditioning 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 AUTO mode.
CAUTION
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.
