Malfunction indicator
The VSM can be deactivated even if
you don’t cancel the VSM operation
by pressing the ESC OFF button. It
indicates that a malfunction has
been detected somewhere in the
Electric Power Steering system or
VSM system. If the ESC indicator
light ( ) or EPS warning light
remains on, take your vehicle to an
authorized Kia dealer and have the
system checked.
✽ ✽
NOTICE
• The VSM is designed to function
above approximately 13 mph (22
km/h) on curves.
• The VSM is designed to function above approximately 6 mph (10
km/h) when a vehicle is braking on
a split-mu surface. A split-mu sur-
face is made of two surfaces which
have different friction forces.
The Vehicle Stability Management
system is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility of the driver to always check
the speed and the distance to the
vehicle ahead. Always hold the
steering wheel firmly while driving.
Your vehicle is designed to activate according to the driver’s intention,
even with installed VSM. Always fol-
low all the normal precautions for
driving at safe speeds for the condi-
tions – including driving in inclement
weather and on a slippery road.Hill-start assist control (HAC)
A vehicle has the tendency to roll
back on a steep hill when it starts to
go after stopping. The Hill-start
Assist Control (HAC) prevents the
vehicle from rolling back by applying
the brakes automatically for about 2
seconds. The brakes are released
when the accelerator pedal is
depressed or after about 2 seconds.
The HAC is activated only for about 2
seconds, so when the vehicle is
starting off always depress the accel-
erator pedal.
WARNING
For maximum protection, always
wear your seat belt. No system,
no matter how advanced, can
compensate for all driver error
and/or driving conditions.
Always drive responsibly.

Driving your vehicle
- It will operate if the vehicle speed isgreater than 5 mph (8 km/h) and
less than or equal to 38 mph (60
km/h) on a forward vehicle.
(Depending on the condition of the
vehicle ahead and the environment
surrounding it, the possible maxi-
mum operating speed may be
reduced.)Brake operation
In an urgent situation, the FCAsystem applies the brakes.
The FCA 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 accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat- ically canceled, when risk factors
disappear.
CAUTION
The driver should always paygreat caution to vehicle opera-tion, even though there is nowarning message or warningalarm. The warning of the FCAsystem may not sound whileother system warning sounds.
WARNING
The FCA system logic assesses
the risk of a collision by moni-
toring several variables, such
as the distance from the vehicle
ahead, the speed of the vehicle
ahead, and the driver's vehicle
speed. Certain conditions, such
as inclement weather and road
conditions, may affect the oper-
ation of the FCA system.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING
The FCA cannot avoid all colli-
sions. The braking control can-
not completely stop the vehicle.
The driver is responsible to
safely drive and control the
vehicle.

Driving your vehicle
When ECO is activated:
The acceleration may slightly bereduced even though you depress
the accelerator fully.
The air conditioner performance may be limited
The shift pattern of the automatic transmission may change.
The engine noise may get louder.
The above situations are normal
conditions when the Eco System is
activated to help improve fuel effi-
ciency in certain situations.
Limitation of ECO operation:
If the following conditions occur while
ECO is operating, the system opera-
tion is limited even though there is no
change in the ECO indicator.
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 ondynamic driving by auto-
matically adjusting the
steering wheel, engine
and transmission 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.

Driving your vehicle
Remember, your vehicle does notrequire 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.
Opening 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,
turning off the engine start/stop
button 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 transmission shift lever in N (Neutral).
Release the parking brake.
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 transmission 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
transmission
To avoid serious damage to the automatic transmission,limit the vehicle speed to 10mph (15 km/h) and drive lessthan 1 mile (1.5 km) when tow-ing.
Before towing, check the auto- matic transmission for fluidleaks under your vehicle. If theautomatic transmission fluidis leaking, flatbed equipmentor a towing dolly must beused.
