Vehicle to vehicle distance
setting
To set vehicle to vehicle distance:
This function allows you to program
the vehicle to maintain relative dis-
tance to the vehicle ahead without
depressing the accelerator pedal or
brake pedal.
The vehicle to vehicle distance will
automatically activate when the
Smart Cruise Control system is on.
Select the appropriate distance
according to road conditions and
vehicle speed. Each time the button is pressed, the
vehicle to vehicle distance changes
as follows:
For example, if you drive at 56 mph
(90 km/h), the distance maintain as
follows;
Distance 4 - approximately 172 feet
(52.5 m)
Distance 3 - approximately 130 feet
(40 m)
Distance 2 - approximately 106 feet
(32.5 m)
Distance 1 - approximately 82 feet
(25 m)
✽ ✽
NOTICE
The distance is set to the last set dis-
tance when the system is used for the
first time after starting the engine.

If you push the Smart CruiseControl toggle switch (RES+ or
SET-) while Auto Hold and Smart
Cruise Control is operating, the
Auto Hold will be released regard-
less of accelerator pedal operation
and the vehicle will start to move.
The AUTO HOLD indicator
changes from green to white. (if
equipped with EPB (Electronic
Parking Brake))Radar to detect distance to the
vehicle ahead
The sensor detects the distance to
the vehicle ahead.
If the sensor is covered with dirt or
other foreign matter, the vehicle to
vehicle distance control may not
operate correctly.
Always keep the area in front of the
sensor clean.
Warning message
When the sensor lens cover is blocked
with dirt, snow, or debris, the Smart
Cruise Control System operation may
stop temporarily. If this occurs, a warn-
ing message will appear on the LCD
display. Remove any dirt, snow, or
debris and clean the radar sensor lens
cover before operating the Smart
Cruise Control System. The Smart
Cruise Control system may not prop-
erly activate, if the radar is totally con-
taminated, or if any substance is not
detected after turning ON the engine
(e.g. in an open terrain).OJFH056162N

To adjust the sensitivity of
Smart Cruise Control
The sensitivity of vehicle speed when
following the front vehicle to maintain
the set distance can be adjusted. Go
to the User Settings Mode (Driver
Assistance) and select (SCC
Reaction). You may select one of the
three stages you prefer.
Slow:Vehicle speed to the vehicle ahead
to maintain the set distance is
slower than normal speed.
Normal: Vehicle speed to the vehicle ahead
to maintain the set distance is nor-
mal.
Fast: Vehicle speed to the vehicle ahead
to maintain the set distance is
faster than normal speed.
✽ ✽ NOTICE
The last selected mode remains in
the system.
To convert to cruise control
mode:
The driver may choose to only use
the cruise control mode (speed con-
trol function) by doing as follows: 1. Turn the Smart Cruise Control
system on (the cruise indicator
light will be on but the system will
not be activated).
2. Push the distance to distance switch for more than 2 seconds.
3. Choose between "Smart Cruise Control" and "Cruise Control".
When the system is canceled using
the CRUISE button or the CRUISE
button is used after the engine is
turned on, the Smart Cruise Control
mode will turn on.

WARNING
When using the cruise control
mode, you must manually
adjust the distance to other
vehicles as the system will not
automatically brake to slow
down for other vehicles.

Hybrid vehicleThe drive mode may be selected
according to the driver’s preference
or road condition.
The system resets to the ECO mode
when the hybrid system is restarted.
If there is a problem with the instru-
ment cluster, the drive mode will be
in ECO mode and may not change to
NORMAL mode or SPORT mode.
The mode changes whenever the
DRIVE MODE button is pressed.
\b When normal mode is selected, it
is not displayed on the cluster.ECO mode (Active ECO)
Active ECO is designed to
help improve fuel efficien-
cy by controlling certain
engine and transaxle sys-
tem operating parame-
ters. Fuel efficiency
depends on the driver's
driving habit and road
condition.
When the DRIVE MODE button is pressed and the ECO mode is
selected, the ECO indicator
(green) will illuminate to show that
Active ECO is operating.
When Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn
off the system, press the DRIVE
MODE button again.

Driving your vehicle
When Active ECO is activated:
The acceleration may slightly bereduced even though you depress
the accelerator fully.
The air conditioner performance may be limited
The shift pattern of the automatic transaxle may change.
The engine noise may get louder.
The above situations are normal
conditions when the Active Eco
System is activated to help improve
fuel efficiency in certain situations.
Limitation of Active ECO oper-
ation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
When the coolant temperature is low:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
the engine torque is restricted.
When using manual mode: The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds:
The system will be limited, judging
that the driver wants to speed up.
SPORT mode
SPORT mode focuses ondynamic driving by auto-
matically adjusting the
steering wheel, engine
and transaxle system.
When the DRIVE MODE button is pressed and the SPORT mode is
selected, the SPORT indicator
(yellow) will illuminate.
Whenever the hybrid system is restarted, the Drive Mode will revert
back to ECO mode. If SPORT
mode is desired, re-select SPORT
mode from the DRIVE MODE but-
ton.
If the system is activated: - While holding vehicle speed, itmaintains the gear and RPM for
some time even though the accel-
erator pedal is not depressed.
- Up-shifting is delayed.

In Sport drive mode, the fuel effi-
ciency may decrease.

Your vehicle's fuel economy depends
mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos- sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 8. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 8 for details).
Keep your vehicle clean. For maxi- mum service, your vehicle should
be kept clean and free of corrosive
materials. It is especially important
that mud, dirt, ice, etc. not be
allowed to accumulate on the
underside of the vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.
