SPORT mode
SPORT mode manages the
driving dynamics by
automatically adjusting the
steering effort, the engine
and transmission control
logic for enhanced driver
performance.

[ When SPORT mode is selected by
using the DRIVE MODE button, the
SPORT indicator will illuminate.

[ Whenever the engine is restarted,
the Drive Mode will revert back to
NORMAL 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 remain raised over a certain length of time
even after releasing the accelerator
- Upshifts are delayed when accelerating
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 (for example, Economic
or Aggressive (Sportive) from
the brake pedal depression or
the steering wheel operation.

[ Toggle the DRIVE MODE button to
select SMART mode. When SMART
mode is selected, the indicator
illuminates on the instrument cluster.

[ SMART mode automatically controls
the vehicle driving, such as gear
shifting patterns and engine torque,
in accordance with the driver’s driving
habits.

[ Whenever the engine is restarted, the
drive mode remains in SMART mode.
Information

[When you mildly drive the vehicle
in SMART mode, the driving mode
changes to SMART 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).

[ When you dynamically drive the
vehicle in SMART mode by abruptly
decelerating or sharply turning the
driving mode changes to SMART
SPORT mode. However, it may
adversely affect fuel economy.

Driving Your Vehicle6-56
Various driving situations, which you may
encounter in SMART mode

[ The driving mode aut
omatically
changes to SMART ECO mode after
a certain period of time, when you
gently depress the accelerator pedal
(Your driving is categorized to be
economic.).

[ The driving mode automatically
changes from SMART ECO mode to
SMART NORMAL mode after a certain
period of time, when you sharply or
repetitively depress the accelerator
pedal.

[ The driving mode automatically
changes to SMART NORMAL 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.

[ 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.

[ 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 situations,
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
f
ollowing situations. (The OFF indicator
illuminates in those situations.)

[ The cruise control is activated :
The cruise control system may
deactivate the SMART mode when
the vehicle is controlled by the set
speed of Smart Cruise Control system.
(SMART mode is not deactivated
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 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.

Driving Your Vehicle6-58
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the below
suggestions:

[ Drive cautiously and keep a longer
braking distance.

[ Avoid abrupt braking or steering.

[ When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.

[ Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an intelligent
variable transmission while driving on
slippery surfaces can cause an accident.
The sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the Vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
of the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire
or other damage. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tires
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).
Information
The ESC system must be turned OFF
before rocking the vehicle.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage to
the transmission, and tire damage. See
"Towing" in chapter 7.

Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or adversely
affect vehicle handling. This could lead
to sudden tire failure that may cause
loss of vehicle control resulting in an
accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
