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.
✽ ✽NOTICEThe 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)
STEERING WHEEL
CAUTION
 If the Electric Power Steering
System does not operate nor-mally, the warning light willilluminate on the instrumentcluster. The steering wheelmay require increased steer-ing effort. Take your vehicle toan authorized Kia dealer andhave the vehicle checked assoon as possible.
 When you operate the steering wheel in low temperature,noise may occur. If temperaturerises, the noise will likely disap-pear. This is a normal condition.
 When the vehicle is stationary, when the steering wheel isturned all the way to the left orright continuously, the steer-ing wheel becomes harder toturn. The power assist is limit-ed to protect the motor fromoverheating.
As time passes, the steeringwheel return to its normalcondition.

Driving your vehicle
✽
✽NOTICE• Do not drive in water if the level is
higher than the bottom of the vehi-
cle.
• Check your brake condition once you are out of mud or water. Press
the brake pedal several times as
you move slowly until you feel nor-
mal braking forces return.
• Shorten your scheduled mainte- nance interval if you drive in off-
road conditions such as sand, mud
or water (see “Maintenance under
severe usage conditions” in chap-
ter 7). Always wash your vehicle
thoroughly after off-road use,
especially cleaning the bottom of
the vehicle.
• Since the driving torque is always applied to the 4 wheels the per-
formance of the AWD vehicle is
greatly affected by the condition of
the tires. Be sure to equip the vehi-
cle with four tires of the same size
and type.
• A full time four wheel drive vehi- cle cannot be towed by an ordi-
nary tow truck. Make sure that
the vehicle is placed on a flat bed
truck for moving.
WARNING
- Drivingthrough
water
Drive slowly. If you are driving
too fast in water, the water can
get into the engine compart-
ment and wet the ignition sys-
tem, causing your vehicle to
suddenly stop. If this happens
and your vehicle is in a tilted
position, your vehicle may roll
over.
WARNING
- AWD driving
 Avoid high cornering speed.
 Do not make quick steering
wheel movements, such as
sharp lane changes or fast,
sharp turns.
 The risk of rollover is greatly increased if you lose control
of your vehicle at high speed.
 In a collision, an unbelted per- son is significantly more like-
ly to die compared to a person
wearing a seat belt.
 Loss of control often occurs if two or more wheels drop off
the roadway and the driver
oversteers to re-enter the
roadway. In the event your
vehicle leaves the roadway, do
not steer sharply. Instead,
slow down before pulling
back into the travel lanes.

What to do in an emergency14
6Then position the wrench as shown
in the drawing and tighten the wheel
nuts. Be sure the socket is seated
completely over the nut. Do not stand
on the wrench handle or use an
extension pipe over the wrench han-
dle. Go around the wheel tightening
every nut following the numerical
sequence shown in the image until
they are all tight. Then double-check
each nut for tightness. After changing
wheels, have an authorized Kia deal-
er tighten the wheel nuts to their
proper torque as soon as possible.
Wheel nut tightening torque:
9~11 kg·m (65~79 lb·ft) If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting the tire pressure. If the cap
is not replaced, dust and dirt may get
into the tire valve and air may leak
from the tire. If you lose a valve cap,
buy another and install it as soon as
possible.
After you have changed the wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.
CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Installation of a non-metricthread nut on a metric stud orvice-versa will not secure thewheel to the hub properly andwill damage the stud so that itmust be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installingaftermarket lug nuts or wheels.If in doubt, consult an author-ized Kia dealer.

Maintenance30
7Parking brakeInspect the parking brake system
including the parking brake lever (or
pedal) and cables.Brake discs, pads, calipers
and rotorsCheck the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.Exhaust pipe and mufflerVisually 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 boltsCheck the suspension connections
for looseness or damage. Retighten
to the specified torque.Steering gear box, linkage &
boots/lower arm ball jointWith 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.Power steering pump, belt and
hoses (if equipped)Check the power steering pump and
hoses for leakage and damage.
Replace any damaged or leaking
parts immediately. Inspect the power
steering belt (or drive belt) for evi-
dence of cuts, cracks, excessive
wear, oiliness and proper tension.
Replace or adjust it if necessary.
Drive shafts and bootsCheck 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.
