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.

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.

7. Shut off the vehicle and release thevehicle brakes but leave the parking
brake set.
When you are ready to leave after park-
ing on a hill
1. With the automatic transaxle in P (Park), apply your brakes and hold the
brake pedal down while you:

and

2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.E140500AUN
Maintenance when trailer towing
Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to frequently check. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and hitch. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all hitch nuts
and bolts should be tight.
WARNING- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others could be seriously or
fatally injured.
CAUTION
Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicatesover-heating, switch off the A/Cand stop the vehicle in a safe area to cool down the engine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with the air conditioner, youshould install a condenser fan toimprove engine performancewhen towing a trailer.

Jump starting procedure
1. Make sure the booster battery is 12-volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2). Proceed to
connect one end of the other jumper
cable to the negative terminal of the
booster battery (3), then the other end
to a solid, stationary, metallic point (for
example, the engine lifting bracket)
away from the battery (4). Do not con-
nect it to or near any part that moves
when the engine is cranked.
Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections. 5. Start the engine of the vehicle with the
booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging isnot apparent, you should have your vehi-cle checked by an authorized KIA dealer.

Push-starting
Your manual transaxle-equipped vehicle
should not be push-started because it
might damage the emission control sys-
tem.
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this section for
jump-starting.
CAUTION- Battery cables
Do not connect the jumper cable from the negative terminal of thebooster battery to the negative ter-minal of the discharged battery.This can cause the discharged bat- tery to overheat and crack, releas-ing battery acid.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.

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.
