Various driving situations, which you may
encounter in SMART mode
• 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 in SMART
NORMAL mode. Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indicator
illuminates in those situations.)
•
The driver uses the paddle shifter
(manual shift mode) :
It deactivates SMART mode. The
vehicle drives, as the driver manually
changes gear with the paddle shifter.
• 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.

Forward Collision-Avoidance Assist
system is designed to detect the
vehicle, a pedestrian or cyclist ahead (if
equipped) in the roadway through front
radar signals and front view camera
recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
WARNING
Take the following precautions when
using Forward Collision-Avoidance
Assist system:
• This system is only a supplemental
system and it is not intended to,
nor does it replace the need for
extreme care and attention of
the driver. The sensing range and
objects detectable by the sensors
are limited. Pay attention to the road
conditions at all times.
• Drive at posted speed limits and
accordance to road conditions.
• Always drive cautiously to prevent
unexpected and sudden situations
from occurring. FCA does not always
stop the vehicle completely.

Brake operation
• In an urgent situation, the braking
system enters into the ready status for
prompt reaction against the driver’s
depressing the brake pedal.
• FCA provides additional braking
power for optimum braking
performance, when the driver
depresses the brake pedal.
• The braking control is automatically
deactivated, when the driver sharply
depresses the accelerator pedal, or
when the driver abruptly operates the
steering wheel.
• FCA brake control is automatically
canceled, when risk factors disappear.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not there is a
warning message or alarm from FCA
system.
• After the brake control is activated,
the driver must immediately depress
the brake pedal and check the
surroundings. The brake activation
by the system lasts for about 2
seconds.
