Electric power steering (EPS)
The power steering uses a motor to
assist you in steering the vehicle. If
the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
The motor driven power steering is
controlled by a power steering con-
trol unit which senses the steering
wheel torque and vehicle speed to
command the motor.
The steering becomes heavier as the
vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for optimum steer-
ing control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering checked by an authorized
Kia dealer. If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steering
wheel may require increased
steering effort. Take your vehicle to
an authorized Kia dealer and have
the vehicle checked as soon as
possible.
When you operate the steering wheel in low temperature, noise
may occur. If temperature rises, the
noise will likely disappear. This is a
normal condition.
When the vehicle is stationary, and the steering wheel is turned all the
way to the left or right continuous-
ly, the steering wheel becomes
harder to turn. The power assist is
limited to protect the motor from
overheating.
As time passes, the steering wheel
will return to its normal condition.
✽ ✽ NOTICE
The following symptoms may occur
during normal vehicle operation:
• The EPS warning light does not
illuminate.
• The steering gets heavy immedi- ately after turning the Engine
Start/Stop button is ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering wheel will return
to its normal condition.
• A click noise may be heard from the EPS relay after turning the
Engine Start/Stop button is ON or
OFF position.
• A motor noise may be heard when the vehicle is at a stop or at a low
driving speed.
• If the Electric Power Steering System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steer-
ing wheel may become difficult to
control or operate abnormally.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible. (Continued)

Driving your 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.

IF YOU HAVE A FLAT TIRE (WITH TIRE MOBILITY KIT)
Please read the instructions before
using the Tire Mobility Kit.
(1) Compressor
(2) Sealant bottle The Tire Mobility Kit is a temporary
fix to the tire and the tire should be
inspected by an authorized Kia deal-
er as soon as possible.
When two or more tires are flat, do
not use the tire mobility kit because
the one supplied canister of sealant
in the Tire Mobility Kit is to only
enough sealant for one flat tire.
Have your tire repaired as soon as
possible. The tire may lose air pres-
sure at any time after inflating with
the Tire Mobility Kit.
✽ ✽
NOTICE
When repairing a flat tire with the
Tire Mobility Kit (TMK), quickly
remove the sealant on the tire pres-
sure sensor and wheel. When
installing the repaired tire and
wheel, tighten the wheel nut to a
torque value of 11 ~ 13kgf·m.
OJFH067043WARNING- Tire wall
Do not use the Tire Mobility Kit
to repair punctures in the tire
walls. This can result in an acci-
dent due to tire failure.

Maintenance
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.

CAUTION
When replacing tires, use the same size originally supplied with the vehicle. Using tires of a different size can damage the related parts or make them work irregularly.
✽
✽ NOTICE
• It is permissible to add 3psi to the standard tire pressure specification if colder temperatures are expected soon.
Tires typically loose 1psi for every 12°F temperature drop. If extreme temperature variations are expected, re-
check your tire pressure as necessary to keep them properly inflated.
• We recommend that when replacing tires, use the same originally supplied with the vehicles. If not, that aff\
ects driving performance.
• When driving in high altitude grades, it is natural for the atmospheric pressure to decrease. Therefore, please check the tire pressure and add more air when necessary.
Additionally required tire air pressure per km above sea level: 1.5psi/km
