NOTICE
• The HAC does not operate when
the transaxle shift lever is in the P
(Park) or N (Neutral) position.
• The HAC activates even though
the ESC is off but it does not acti‐
vate when the ESC has malfunc‐
tioned.
Emergency Stop Signal (ESS) (if
equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking the
stop light when the vehicle is braked
rapidly and severely.
The system is activated when:
• The vehicle suddenly stops (vehicle
speed is over 55 km/h and the vehicle
deceleration at greater than 7 m/s
• The ABS is activating.
When the vehicle speed is under
40 km/h and the ABS deactivates or
the sudden stop situation is over, the
stop light blinking will stop. Instead, the
hazard warning flasher will turn on au‐
tomatically.
The hazard warning flasher will turn off
when vehicle speed is over 10 km/h af‐
ter the vehicle has stopped. Also, it will
turn off when the vehicle is driven at
low speed for some time. You can turn
it off manually by pushing the hazard
warning flasher switch.
CAUTION
The Emergency Stop Signal (ESS)
system will not work if the hazard
warning flasher is already on.

brake as far as possible and fully
engage the vehicle's transaxle into
the P (Park) position. If the parking
brake is not fully engaged, the ve‐
hicle may move inadvertently and
injure yourself and others.
(Continued)
(Continued)
• All vehicles should always have the
parking brake fully engaged when
parking to avoid inadvertent
movement of the vehicle which
can injure occupants or pedes‐
trians.
• Check to be sure the parking brake is
not engaged and that the parking
brake indicator light is out before
driving away.
• Driving through water may get the
brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your vehi‐
cle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the ve‐
hicle under control at all times. If the
braking action does not return to
normal, stop as soon as it is safe to
do so and we recommend that you
call an authorized Kia dealer.
