Driving your vehicle

Various driving situations, which you may

encounter in SMART mode

śꢀ The driving mode automatically

changes to ECO mode after a certain

period of time, when you gently

depress the accelerator pedal (Your

driving is categorized to be mild.).

śꢀ The driving mode automatically

changes from SMART ECO mode

to SMART COMFORT mode after a

certain period of time, when you

sharply or repetitively depress the

accelerator pedal.

SMART mode

SMART mode selects the

proper driving mode among

ECO, COMFORT and SPORT

by judging the driver's driving

habits (for example, mild or

dynamic) from the brake pedal

depression or the steering

wheel operation.

śꢀ Press the DRIVE MODE button to

activate SMART mode. When SMART

mode is activated, the indicator

illuminates on the instrument cluster.

śꢀ The driving mode automatically

changes to SMART COMFORT mode

with the same driving patterns, when

the vehicle starts to drive on an

upward slope of a certain angle. The

driving mode automatically returns to

SMART ECO mode, when the vehicle

enters a leveled road.

śꢀ The vehicle starts in SMART mode,

when the engine was turned OFF in

SMART mode.

śꢀ SMART mode automatically controls

gear shifting patterns, engine torque,

in accordance with the driver's driving

habits.

śꢀ The driving mode automatically

changes 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.

Information

śꢀ When you mildly drive the vehicle

in SMART mode, the driving mode

changes to ECO mode to improve fuel

efficiency. However, the actual fuel

efficiency may differ in accordance

with your driving situations (for

example, upward/downward slope,

vehicle deceleration/acceleration).

śꢀ You may still sense the engine brake

performance, even when you release

the accelerator pedal in SMART

SPORT mode. It is because your

vehicle remains to be in a lower gear

over a certain period of time for next

acceleration. Thus, it is a normal

driving situation, not indicating any

malfunction.

śꢀ When you dynamically drive the

vehicle in SMART mode by abruptly

decelerating or sharply curving, the

driving mode changes to SPORT mode.

However, it may adversely affect fuel

economy.

6-68

śꢀ The driving mode automatically

changes to SMART SPORT mode

only in harsh driving situations. In

most of the normal driving situations,

the driving mode sets to be either

in SMART ECO mode or in SMART

COMFORT mode.

Limitation of SMART mode

The SMART mode may be limited in

following situations. (The OFF indicator

illuminates in those situations.)

śꢀ The driver manually moves the shift

button : It deactivates SMART mode.

The vehicle drives, as the driver

manually moves the shift button.

śꢀ The cruise control is activated : The

cruise system may deactivate the

SMART mode. When a higher system

is set by the cruise system, it starts to

control vehicle speed and deactivates

SMART mode. (SMART mode is not

deactivated just by activing the cruise

system.)

śꢀ The transmission oil temperature is either

extremely low or extremely high : The

SMART mode can be active in most of

the normal driving situations. However,

an extremely high/ low transmission oil

temperature may temporarily deactivate

the SMART mode, because the

transmission condition is out of normal

operation condition.
