ECO mode
When the Drive Mode isset to ECO mode, the
engine and transmission
control logic are changed
to maximize fuel efficiency.
When the ECO mode is selected by pressing the DRIVE MODE but-
ton, the ECO indicator will illumi-
nate.
If the vehicle is set to ECO mode, when the engine is turned OFF
and restarted the Drive Mode set-
ting will remain in ECO mode.
Information
Fuel efficiency depends on the driver's
driving habit and road condition. When ECO mode is activated:
The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The shift pattern of the automatic transmission may change.
The engine noise may get louder.
The above situations are normal
conditions when ECO mode is acti-
vated to improve fuel efficiency. Limitation of ECO mode opera-
tion:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though
there is no change in ECO indicator.
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
engine torque is restricted.
When driving the vehicle with the automatic transmission gear shift
lever in manual shift mode:
The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply depressed for a few seconds:
The system will be limited, judging
that the driver wants to speed up.

SPORT mode
SPORT mode managesthe driving dynamics by
automatically adjusting the
steering effort, the engine
and transmission control
logic for enhanced driver
performance.
When SPORT mode is selected by pressing the DRIVE MODE button,
the SPORT indicator will illuminate.
Whenever the engine is restarted, the Drive Mode will revert back to
COMFORT mode. If SPORT mode
is desired, re-select SPORT mode
from the DRIVE MODE button.
When SPORT mode is activated: - The engine rpm will tend to remainraised over a certain length of time
even after releasing the accelerator
- Upshifts are delayed when accel- erating
Information
In SPORT mode, the fuel efficiency
may decrease.
SMART mode
SMART mode selects the
proper driving mode
among ECO, NORMAL,
and SPORT by judging the
driver's driving habits (i.e. mild or
dynamic) from the brake pedal
depression or the steering wheel
operation.
Press the DRIVE MODE button to activate SMART mode. When
SMART mode is activated, the
indicator illuminates on the instru-
ment cluster.
The indicator illuminates in green, when the driver's driving is catego-
rized to be mild. It illuminates in
white, when the driver's driving is
categorized to be normal. It illumi-
nates in yellow, when the driver's
driving is categorized to be dynam-
ic during abrupt braking or sharp
curving.
The vehicle starts in SMART mode again, when the engine was turned
OFF in SMART mode. SMART mode automatically con-
trols the vehicle driving, such as
gear shifting patterns, engine
torque, and riding quality in accor-
dance with the driver's driving
habits.
Information
• When you mildly drive the vehiclein SMART mode, the driving mode
changes to ECO mode to improve
fuel efficiency. However, the actual
fuel efficiency may differ in accor-
dance with your driving situations
(i.e. upward/downward slope, vehi-
cle deceleration/acceleration).
• When you dynamically drive the vehicle in SMART mode by abrupt-
ly decelerating or sharply turning
the driving mode changes to SPORT
mode. However, it may adversely
affect fuel economy.

Driving your vehicle
The driving mode automaticallychanges to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
You may still sense the engine braking performance, even when
you release the accelerator pedal
in SMART SPORT mode. It is
because your vehicle remains in
lower gear over a certain period of
time for next acceleration. Thus, it
is a normal driving situation, not
indicating any malfunction.
The driving mode automatically changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situa-
tions, the driving mode sets to be
either in SMART ECO mode or in
SMART NORMAL mode.Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indica-
tor illuminates in those situations.)
The driver manually moves theshift lever :
It deactivates SMART mode. The
vehicle drives, as the driver manu-
ally moves the shift lever.
The cruise control is activated : The cruise control system may
deactivate the SMART mode when
the vehicle is controlled by the set
speed of the smart cruise control
system. (SMART mode is not deac-
tivated just by activating the cruise
control system.)
The transmission oil temperature is either extremely low or extremely
high :
The SMART mode can be active in
most of the normal driving situa-
tions. However, an extremely high/
low transmission oil temperature
may temporarily deactivate the
SMART mode, because the trans-
mission condition is out of normal
operation condition.
