Power steering
Power steering uses energy from the
engine to assist you in steering the vehi-
cle. If the engine is off or if the power
steering system becomes inoperative,
the vehicle may still be steered, but it will
require increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized KIA dealer.
✽ ✽
NOTICE
If the power steering drive belt breaks
or if the power steering pump malfunc-
tions, the steering effort will greatly
increase.
✽ ✽NOTICE
If the vehicle is parked for extended
periods outside in cold weather (below -
10°C/14°F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-
function.
When this happens, increase the engine
RPM by depressing accelerator until the
RPM reaches 1,500 rpm then release or
let the engine idle for two or three min-
utes to warm up the fluid.

Tilt steering
Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise it to give your legs more room
when you exit and enter the vehicle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.
STEERING WHEEL
CAUTION
Never hold the steering wheel
against a stop (extreme right or leftturn) for more than 5 seconds withthe engine running. Holding the steering wheel for more than 5 sec-onds in either position may causedamage to the power steeringpump.
WARNING
Never adjust the angle of the steering wheel while driving. You
may lose steering control and
cause severe personal injury,
death or accidents.
After adjusting, push the steering wheel both up and down to be
certain it is locked in position.

WARNING
Never press the engine start/stop
button for more than 3 seconds
or 3 times successively when the
vehicle is moving. This would
result in the engine turning off
and loss of power assist for the
steering and brakes, which may
lead to loss of directional control
and braking function, which
could cause an accident.
Before leaving the driver’s seat, always make sure the shift lever
is engaged in P
(Park),set the
parking brake fully and shut the
engine off. Unexpected and sud-
den vehicle movement may occur
if these precautions are not
taken.
(Continued)
(Continued)
Never reach for the enginestart/stop button, or any other
controls through the steering
wheel while the vehicle is in
motion. The presence of your
hand or arm in this area could
cause a loss of vehicle control,
an accident and serious bodily
injury or death.
Do not place any movable objects around the driver’s seat as they
may move while driving, interfere
with the driver and lead to an
accident.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
E070101AUN
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
WARNING- Brakes
Do not drive with your foot rest-
ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to safely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45
mph) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transaxle.
E140407BUN-EU
Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down hill. However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the direction
of the curb (right if headed down hill,
left if headed up hill).
2. If the vehicle has a manual transaxle, place the car in neutral. If the vehicle
has an automatic transaxle, place the
car in P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place chocks under the trailer wheels on the down hill side of the wheels.
5. Start the vehicle, hold the brakes, shift to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes, reapply the park- ing brake and shift the vehicle to R
(Reverse) for manual transaxle or P
(Park) automatic transaxle.
CAUTION
When towing a trailer on steep grades (in excess of 6%) payclose attention to the enginecoolant temperature gauge toensure the engine does not over- heat. If the needle of the coolanttemperature gauge moves acrossthe dial towards “H” (HOT), pullover and stop as soon as it is safeto do so, and allow the engine toidle until it cools down. You mayproceed once the engine hascooled sufficiently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-bility of engine and transaxleoverheating.
WARNING
Failure to use an approved trailer
wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.
WARNING- Parking on a hill.
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break loose.

Jump starting
Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.
CAUTION
Use only a 12-volt jumper system.You can damage a 12-volt startingmotor, ignition system, and otherelectrical parts beyond repair byuse of a 24-volt power supply (either two 12-volt batteries in series or a24-volt motor generator set).WARNING- Battery
• Keep all flames or sparks away from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
If these instructions are not fol-
lowed exactly, serious personal
injury and damage to the vehicle
may occur! If you are not sure
how to follow this procedure,
seek qualified assistance.
Automobile batteries contain sul-
furic acid. This is poisonous and
highly corrosive. When jump
starting, wear protective glasses
and be careful not to get acid on
yourself, your clothing or on the
car.
Do not attempt to jump start the vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.1VQA4001

IF THE ENGINE OVERHEATS
F050000AMG
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as itis safe to do so.
2. Place the shift lever in P (Park) and set the parking brake. If the air conditioning
is on, turn it off.
3. If engine coolant is running out under the car or steam is coming out from
the hood, stop the engine. Do not open
the hood until the coolant has stopped
running or the steaming has stopped.
If there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be sure
the engine cooling fan is operating. If
the fan is not running, turn the engine
off. 4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop).
5. If the water pump drive belt is broken or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized KIA dealer for
assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, call an author-
ized KIA dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling systemand this should be checked as soonas possible by an authorized KIAdealer.

Use a towing strap less than 5 m (16
feet) long. Attach a white or red cloth
(about 30 cm (12 inches) wide) in the
middle of the strap for easy visibility.
Drive carefully so that the towing strap is not loosened during towing.
F080301AUN
Emergency towing precautions
Turn the ignition switch to ACC so thesteering wheel isn’t locked.
Place the transaxle 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 steering system
will be disabled.
If you are driving down a long hill, the brakes may overheat and brake per-
formance will be reduced. Stop often
and let the brakes cool off.
WARNING
Use extreme caution when towing
the vehicle.
driving maneuvers which would
place excessive stress on the
emergency towing hook and tow-
ing cable or chain. The hook and
towing cable or chain may break
and cause serious injury or dam-
age.
If the disabled vehicle is cannot be moved, do not forcibly contin-
ue the towing. Contact an author-
ized KIA dealer or a commercial
tow truck service for assistance.
Tow the vehicle as straight ahead as possible.
Keep away from the vehicle dur- ing towing.
OUN046024CAUTION -Automatic
transaxle
If the car is being towed with all four wheels on the ground, it canbe towed only from the front. Be sure that the transaxle is in neu-tral. Be sure the steering is unlocked by placing the ignitionswitch in the ACC position. A driver must be in the towed vehi-cle to operate the steering and brakes.
To avoid serious damage to the automatic transaxle, limit thevehicle speed to 15 km/h (10 mph) and drive less than 1.5 km (1mile) when towing.
