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.

If you do decide to pull a trailer
Here are some important points if you
decide to pull a trailer:
Consider using a sway control. You can
ask a hitch dealer about sway control.
Do not do any towing with your car dur- ing its first 2,000 km (1,200 miles) in
order to allow the engine to properly
break in. Failure to heed this caution
may result in serious engine or
transaxle damage.
When towing a trailer, be sure to con- sult an authorized KIA dealer for fur-
ther information on additional require-
ments such as a towing kit, etc.
Always drive your vehicle at a moder- ate speed (less than 100 km/h / 60
mph).
On a long uphill grade, do not exceed 70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.

Weight of the trailer
How heavy can a trailer safely be? It
should never weigh more than the maxi-
mum trailer weight with trailer brakes. But
even that can be too heavy.
It depends on how you plan to use your
trailer. For example, speed, altitude, road
grades, outside temperature and how
often your vehicle is used to pull a trailer
are all important. The ideal trailer weight
can also depend on any special equip-
ment that you have on your vehicle.
E140602AEN
Weight of the trailer tongue
The tongue load of any trailer is an
important weight to measure because it
affects the total gross vehicle weight
(GVW) of your vehicle. This weight
includes the curb weight of the vehicle,
any cargo you may carry in it, and the
people who will be riding in the vehicle.
And if you will tow a trailer, you must add
the tongue load to the GVW because
your vehicle will also be carrying that
weight.The trailer tongue should weigh a maxi-
mum of 10% of the total loaded trailer
weight, within the limits of the maximum
trailer tongue load permissible. After
you've loaded your trailer, weigh the trail-
er and then the tongue, separately, to
see if the weights are proper. If they
aren’t, you may be able to correct them
simply by moving some items around in
the trailer.
C190E01JM
Tongue Load Total Trailer Weight
WARNING - Trailer
Never load a trailer with more
weight in the rear than in the
front. The front should be loaded
with approximately 60% of the
total trailer load; the rear should
be loaded with approximately 40%
of the total trailer load.
Never exceed the maximum weight limits of the trailer or trail-
er towing equipment. Improper
loading can result in damage to
your vehicle and/or personal
injury. Check weights and loading
at a commercial scale or highway
patrol office equipped with scales.
An improperly loaded trailer can cause loss of vehicle control.C190E02JM

Tire and loading information label
The label located on the driver's door
sill gives the original tire size, cold
tire pressures recommended for your
vehicle, the number of people that
can be in your vehicle and vehicle
capacity weight.
E150101AMG
Vehicle capacity weight:
385 kg (849 lbs.)
Vehicle capacity weight is the maxi-
mum combined weight of occupants
and cargo.
E150102ABH
Seating capacity:
Total : 5 persons (Front seat : 2 persons, Rear seat : 3 persons)
Seating capacity is the maximum
number of occupants including a
driver, your vehicle may carry.
However, the seating capacity may
be reduced based upon the weight of
all of the occupants, and the weight
of the cargo being carried.
Do not overload the vehicle as there
is a limit to the total weight, or load
limit including occupants and cargo,
the vehicle can carry.

Cargo capacity:
The cargo capacity of your vehicle
will increase or decrease depending
on the weight and the number of
occupants.
E150105AUN
Steps for determining correct loadlimit
1. Locate the statement "The com- bined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs.'' on your vehicle's
placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and lug-
gage load capacity. For example, if
the "XXX" amount equals 635 kg
(1400 lbs.), and there will be five
68 kg (150 lbs.) passengers in
your vehicle, the amount of avail-
able cargo and luggage load
capacity is 295 kg (650 lbs.).
(635-340 (5 x 68) = 295 kg or 1400-750 (5 x 150) = 650 lbs.) 5. Determine the combined weight of
luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trail- er, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your
vehicle.

Certification label
The certification label is located on
the driver's door sill at the center pil-
lar.
This label shows the maximum
allowable weight of the fully loaded
vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle, all occupants, fuel and
cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR).
To find out the actual loads on your
front and rear axles, you need to go
to a weigh station and weigh your
vehicle. Your dealer can help you with
this. Be sure to spread out your load
equally on both sides of the center-
line.The label will help you decide how
much cargo and installed equipment
your vehicle can carry.
If you carry items inside your vehicle
- like suitcases, tools, packages, or
anything else - they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash,
the items will keep going and can
cause an injury if they strike the driv-
er or a passenger.WARNING -Over loading
Never exceed the GVWR for your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
cause an accident or vehicle
damage. You can calculate the
weight of your load by weigh-
ing the items (or people)
before putting them in the
vehicle. Be careful not to over-
load your vehicle.
Do not load your vehicle any heavier than the GVWR, either
the maximum front or rear
GAWR and vehicle capacity
weight. If you do, parts,
including tires on your vehicle
can break, and it can change
the way your vehicle handles
and braking ability. This could
cause you to lose control and
crash. Also, overloading can
shorten the life of your vehi-
cle.

WARNING
Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible
tire failure that could lead to a
crash.
Overloading your vehicle can cause increased stopping dis-
tances that could lead to a
crash.
A crash resulting from poor handling, vehicle damage, tire
failure, or increased stopping
distances could result in seri-
ous injury or death.
WARNING - Loose cargo
Items you carry inside your
vehicle can strike and injure
occupants in a sudden stop or
turn, or in a crash.
Put items in the cargo area of your vehicle. Try to spread the
weight evenly.
Never stack items, like suit- cases, inside the vehicle
above the tops of the seats.
Do not leave an unsecured child restraint in your vehicle.
When you carry something inside the vehicle, secure it.CAUTION
Overloading your vehicle may
cause damage. Repairs wouldnot be covered by your warran-ty. Do not overload your vehicle.
Using heavier suspension com- ponents to get added durabilitymight not change your weightratings. Ask your dealer to helpyou load your vehicle the rightway.

CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy.Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If atire frequently needs refilling,have it checked by an author-ized KIA dealer.
Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
TIRES AND WHEELS
G200100AUN
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
G200200AUN-EU
Recommended cold tire inflation
pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, vehicle
handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section
8. All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.
