-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.

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.
