Emergency braking (3rdwarning)
The warning message appears onthe LCD display with the warning
alarms.
The AEB controls the brakes with- in certain limit to release shock
from the collision.
The AEB controls the maximum
brakes just before the collision.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.
The AEB provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the brake pedal,
or when the driver abruptly turns
the steering wheel.
The braking control is automatical- ly canceled, when risk factors dis-
appear.
The driver should always exercise
caution when operating the vehicle,
even though there is no warning
message or warning alarm.
✽ ✽ NOTICE
The AEB operates in accordance
with the risk levels, such as the dis-
tance from the vehicle/passer-by in
front, the speed of the vehicle/pass-
er-by in front, and the driver's vehi-
cle operation. OJF055078L
WARNING
The AEB cannot avoid all colli-
sions. The AEB might not com-
pletely stop the vehicle before
collision, due to ambient weath-
er and road conditions. The
driver has the responsibility to
drive safely and control the
vehicle.

When Active ECO is activated:
The acceleration may slightly be
reduced even though you depress
the accelerator fully.
The air conditioner performance may be limited
The shift pattern of the automatic transaxle may change.
The engine noise may get louder.
The above situations are normal
conditions when the Active Eco
System is activated to improve fuel
efficiency. Limitation of Active ECO opera-
tion:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
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
the engine torque is restricted.
When using manual mode: The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds:
The system will be limited, judging
that the driver wants to speed up.SPORT mode
SPORT mode focuses on
dynamic driving by auto-
matically adjusting the
steering wheel, engine
and transaxle system.
When the DRIVE MODE button is pressed and the SPORT mode is
selected, the SPORT indicator
(yellow) will illuminate.
Whenever the hybrid system is restarted, the Drive Mode will revert
back to ECO mode. If SPORT
mode is desired, re-select SPORT
mode from the DRIVE MODE but-
ton.
If the system is activated: - While holding vehicle speed, itmaintains the gear and RPM for
some time even though the accel-
erator pedal is not depressed.
- Up-shifting is delayed.
✽ ✽

NOTICE
In Sport drive mode, the fuel effi-
ciency may decrease.

Remember, your vehicle does not
require extended warm-up. After
the engine has started, allow the
engine to run for 10 to 20 seconds
prior to placing the vehicle in gear.
In very cold weather, however, give
your engine a slightly longer warm-
up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in a
very high gear resulting in engine
bucking. If this happens, shift to a
lower gear. Over-revving is racing
the engine beyond its safe limit.
This can be avoided by shifting at
the recommended speed. Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset
some of this loss, slow down when
driving in these conditions.
Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized Kia dealer perform
scheduled inspections and mainte-
nance.
WARNING - Engine off during motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without the
engine running. In addition, turn-
ing off the engine start/stop but-
ton while driving could engage
the steering wheel lock resulting
in loss of vehicle steering. Keep
the engine on and downshift to
an appropriate gear for an
engine braking effect.

3. Install the towing hook by turning it
clockwise into the hole until it is
fully secured.
4. Remove the towing hook and install the cover after use.Emergency towing
If towing is necessary, have it
done by an authorized Kia dealer
or a commercial tow truck service. If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook under the front (or rear) of
the vehicle. Use extreme caution
when towing the vehicle. A driver
must be in the vehicle to steer it and
operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speed.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Do not use the tow hooks to pull a
vehicle out of mud, sand or other
conditions from which the vehicle
cannot be driven out under its own
power.
Avoid towing a vehicle heavier than the vehicle doing the towing.
The drivers of both vehicles should communicate with each other fre-
quently.

Emergency towing precautions
Turn the ignition switch to ACC so
the steering wheel isn’t locked.
Place the transaxle shift lever in N (Neutral).
Release the parking bake.
Press the brake pedal with more force than normal since you will
have reduced brake performance.
More steering effort will be required because the power steer-
ing system will be disabled.
If you are driving down a long hill, the brakes may overheat and brake
performance will be reduced. Stop
often and let the brakes cool off. If the car is being towed with all
four wheels on the ground, it can
be towed only from the front. Be
sure that the transaxle is in neutral.
Be sure the steering is unlocked by
placing the ignition switch in the
ACC position. A driver must be in
the towed vehicle to operate the
steering and brakes.
CAUTION - Automatic
transaxle
To avoid serious damage to the automatic transaxle, limitthe vehicle speed to 10 mph(15 km/h) and drive less than 1mile (1.5 km) when towing.
Before towing, check the auto- matic transaxle for fluid leaksunder your vehicle. If the auto-matic transaxle fluid is leak-ing, flatbed equipment or atowing dolly must be used.
