Features of your vehicle
Immobilizer system
Your vehicle is equipped with an
electronic engine immobilizer system
to reduce the risk of unauthorized
vehicle use.
Your immobilizer system is com-
prised of a small transponder in the
ignition key and electronic devices
inside the vehicle.
With the immobilizer system, when-
ever you insert your ignition key into
the ignition switch and turn it to ON
or whenever the engine start/stop
button is changed to the ON position,
it checks and verifies if the ignition
key is valid.
If the key is determined to be valid,
the engine will start.
If the key is determined to be invalid,
the engine will not start.
To activate the immobilizer sys-tem:
Turn the ignition key or change the
engine start/stop button from the ON
position to the OFF position. The
immobilizer system activates auto-
matically. Without a valid ignition key
for your vehicle, the engine will not
start.
To deactivate the immobilizersystem:
Insert the ignition key into the key
cylinder and turn it to the ON position
or change the engine start/stop but-
ton to the ON position.
In order to prevent theft of your vehi-
cle, do not leave spare keys anywhere
in your vehicle. Your Immobilizer pass-
word is a customer unique password
and should be kept confidential. Do
not leave this number anywhere in
your vehicle.
CAUTION - Transmitter
damage
Do not drop, wet or expose thekeyless entry system transmit-ter to heat or sunlight.

Features of your vehicle
Make sure to refuel your vehicle
according to the “Fuel requirements”
suggested in chapter 1.
If the fuel filler cap requires replace-
ment, use only a genuine Kia cap or
the equivalent specified for your vehi-
cle. An incorrect fuel filler cap can
result in a serious malfunction of the
fuel system or emission control sys-
tem.
WARNING- Cell phonefires
Do not use cellular phones
while refueling. Electric current
and/or electronic interference
from cellular phones can poten-
tially ignite fuel vapors causing
WARNING- Smoking
DO NOT use matches or a lighter
and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
WARNING- Refueling & Vehicle fires
When refueling, always shut the
engine off. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire. Once
refueling is complete, check to
make sure the filler cap and
filler door are securely closed,
before starting the engine.CAUTION- Exterior paint
Do not spill fuel on the exterior surfaces of the vehicle. Anytype of fuel spilled on paintedsurfaces may damage the paint.
WARNING- Portable fuel
container
When using an approved portable
fuel container, be sure to place
the container on the ground prior
to refueling. Static electricity dis-
charge from the container can
ignite fuel vapors causing a fire.
Once refueling has begun, con-
tact with the vehicle should be
maintained until the filling is com-
plete. Use only approved portable
plastic fuel containers designed
to carry and store gasoline.

Features of your vehicle
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 ignition
switch on. This happens as the sys-
tem performs the EPS system
diagnostics. When the diagnostics
are completed, the steering wheel
will return to its normal condition.
• A click noise may be heard from the EPS relay after the ignition
switch is turned to the ON or
LOCK (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)

Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds
- It remains on if the parking brake is applied.
When the parking brake is applied.
When the brake fluid level in the reservoir is low.
- If the warning light illuminateswith the parking brake released, it
indicates the brake fluid level in
reservoir is low. If the brake fluid level in the reservoir
is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required (For more details,
refer to “Brake Fluid” in chapter 8).
Then check all brake components
for fluid leaks. If any leaks in the
brake system are still found, the
warning light remains on, or the
brakes do not operate properly, do
not drive the vehicle.
In this case, have your vehicle
towed to an authorized Kia dealer
and inspected. Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure are
required to stop the vehicle.
Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.
Driving the vehicle with a warning
light ON is dangerous. If the Parking
Brake & Brake Fluid Warning Light
illuminate with the parking brake
released, it indicates that the brake
fluid level is low.
In this case, have your vehicle inspect-
ed by an authorized Kia dealer.
