■Raindrop sensor
●If the wiper switch is turned to the position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wipers will operate once to show
that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the
wipers will operate once to indicate that the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 90°C (194°F) or higher, or -15°C
(5°F) or lower, automatic operation may not occur. In this case, operate the wip-
ers in any mode other than AUTO.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
CAUTION
■Caution regarding the use of windshield wipers in AUTO mode
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 fingers etc. do
not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The
fluid may freeze on the windshield and cause low visibility. This may lead to an acci-
dent, resulting in death or serious injury.
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

Selecting conventional constant speed control mode
Constant speed control mode differs from vehicle-to-vehicle distance
control mode. When constant speed control mode is selected, your vehi-
cle will maintain a set speed regardless of whether or not there are other
vehicles in the lane ahead.
Press the “ON-OFF” button to
activate the cruise control.
Press the button again to deacti-
vate the cruise control.
Switch to constant speed con-
trol mode.
(Push the lever forward and
hold for approximately one sec-
ond.)
Constant speed control mode indi-
cator will come on.
When in constant speed control
mode, to return to vehicle-to-vehi-
cle distance control mode, push
the lever forward again and hold
for approximately 1 second.
After the desired speed has been
set, it is not possible to return to
vehicle-to-vehicle distance control
mode.
If the “ENGINE START STOP”
switch is turned off and then turned
to IGNITION ON mode again, the
vehicle will automatically return to
vehicle-to-vehicle distance control
mode.

Detection range of the sensors
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 50 cm (1.6 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.

can only be lowered (only the “∨” side of the switch can be operated).
This switch can only be operated when the back door is open.
●Height control off switch
When the vehicle is stopped with the “ENGINE START STOP” switch in IGNI-
TION ON mode, vehicle height control can be disabled/re-enabled.
■When changing vehicle height modes
Before operating the height selector switch to raise/lower the vehicle height,
ensure that there are no objects in the surrounding area that could damage the
vehicle.
■When “N” mode is selected
During high speed driving, the vehicle height will automatically change to that of
“LO” mode.
■When “HI” mode is selected

km/h (31 mph) or when vehicle speed has exceeded 30 km/h (19 mph) for approx-
imately 10 seconds. Even if vehicle speed is reduced below 30 km/h (19 mph), the
vehicle height will not automatically return to “HI” mode.
■When “LO” mode is selected
The vehicle height will change to that of “N” mode when the engine is restarted.

Driving assist systems
To help enhance driving safety and performance, the following systems
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 prevent any of the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control
→P. 2 7 8
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■Active Torque Control 4WD system (AWD models)
Automatically switches from front-wheel drive to AWD (All-Wheel Drive)
according to driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the
road surface is slippery due to snow or rain etc.
■VSC+ (Vehicle Stability Control +) (if equipped)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance

When the VSC/TRC systems are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator flashes to
indicate that the VSC/TRC sys-
tems are operating.
■VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRC, VSC, hill-start
assist control and EPS systems
Helps to maintain vehicle stability when swerving on slippery road sur-
faces by controlling the brakes and engine output
■PCS (Pre-Crash Safety system) (if equipped)
→P. 2 8 0
■Emergency brake signal
In order to reduce the risk of a rear-end collision, when the brakes are
applied suddenly the stop lights will automatically flash to alert the vehicle
behind
