In case of an emergency16
6If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed using a cable or chain
secured to the emergency towing hook
under the front or rear of the vehicle. Use
extreme caution when towing the vehicle.
A driver must be in the vehicle to steer it
and operate the brakes.
Towing in this manner may be done only
on hard-surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
 Do not use the tow hooks to pull a vehi-
cle out of mud, sand or other condi-
tions from which the vehicle cannot be
driven out under its own power.
 Avoid towing a vehicle heavier than the vehicle doing the towing.
 The drivers of both vehicles should com- municate with each other frequently.✽ ✽ NOTICE• Attach a towing strap to the tow hook.
• Using a portion of the vehicle other
than the tow hooks for towing may
damage the body of your vehicle.
• Use only a cable or chain specifically intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing hook provided.
 Before emergency towing, check that
the hook is not broken or damaged.
 Fasten the towing cable or chain securely to the hook.
 Do not jerk the hook. Apply steady and even force.
 To avoid damaging the hook, do not pull from the side or at a vertical angle.
Always pull straight ahead.
 Use a towing strap less than 5 m (16feet) 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.
CAUTION
Use extreme caution when towingthe vehicle.
 Avoid sudden starts or erratic driving maneuvers which wouldplace excessive stress on theemergency towing hook and tow- ing cable or chain. The hook andtowing cable or chain may break and cause serious injury or dam-age.
 If the towing vehicle does not move easily, do not forcibly continue thetowing. Contact an authorized Kiadealer or a commercial tow truckservice for assistance.
 Tow the vehicle as straight ahead as possible.
 Keep away from the vehicle dur- ing towing.

In case of an emergency
When your vehicle is being towed
by another vehicle other than a tow
truck (in case of an emergency) Turn the ignition switch to ACC so thesteering wheel isn’t locked.
 Place the transaxle shift lever in N (Neutral).
 Release the parking bake.
 Vehicles equipped with automatic transaxles should not exceed 45 km/h
(28 mph) and should not be towed
more than 80 km (50 miles).
 Vehicles equipped with manual transaxle should not be towed in
excess of 88 km/h (55 mph) and
should not be towed more than 645 km
(400 miles).
 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.
✽ ✽ NOTICETo prevent internal damage to the
transaxle, never tow your vehicle from
the rear (backwards) with all four tires
in contact with the surface. Tips for towing a stuck vehicleThe following methods are effective
when your vehicle is stuck in mud, sand
or similar substances that prevent the
vehicle from being driven out under its
own power.
 Remove the soil and sand, etc. from
the front and the back of the tires.
 Place a stone or wood under the tires.

621
In case of an emergency
Always be sure the tire is cold before
inflating to the recommended pres-
sure.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1,6 km (1 mile) in that 3
hour period.✽ ✽NOTICEDo not use any tire sealant if your
vehicle is equipped with a Tire
Pressure Monitoring System. The
liquid sealant can damage the tire
pressure sensors.

67. Place the jack at the front or rear
jacking position closest to the tire
you are changing. Place the jack
at the designated locations under
the frame. The jacking positions
are plates welded to the frame
with two tabs and a raised dot to
index with the jack. 8. Insert the jack handle into the jack
and turn it clockwise, raising the
vehicle until the tire just clears the
ground. This measurement is
approximately 30 mm (1.2 in).
Before removing the wheel lug
nuts, make sure the vehicle is sta-
ble and that there is no chance for
movement or slippage.
9. Remove the wheel lug nuts by turning them counterclockwise,
then remove the wheel.
10. Mount the spare tire into position and install the wheel lug nuts
with the beveled edge inward. 11. Once the wheel lug nuts have
been tightened, lower the vehicle
fully to the ground and continue to
tighten the lug nuts until they are
fully secured. Tighten the wheel
lug nuts firmly in a “star” pattern.
If you are unsure of the tightness
of the wheel lug nuts, have them
checked at the nearest service
station. The specified tightening
torque is 9~11 kgm (65-79 lbft,
88-107 Nm). Improperly tight-
ened wheel lug nuts could cause
brake pedal vibration while brak-
ing.
WARNING
- Jack location
To reduce the possibility of
injury, be sure to use only the
jack provided with the vehicle
and in the correct jack position;
never use any other part of the
vehicle for jack support.

OWNER MAINTENANCE Owner maintenance schedule The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized Kia dealer at
the frequencies indicated to help ensure
safe, dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.When you stop for fuel: Check the engine oil level.
 Check coolant level in coolant reser-voir.
 Check the windshield washer fluid level.
 Look for low or under-inflated tires.
While operating your vehicle: Note any changes in the sound of the exhaust or any smell of exhaust fumes
in the vehicle.
 Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
 Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling on smooth, level road.
 When stopping, listen and check for strange sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
 If any slipping or changes in the oper- ation of your transaxle occurs, check
the transaxle fluid level.
 Check automatic transaxle P (Park) function.
 Check parking brake.
 Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
At least monthly: Check coolant level in the coolantrecovery reservoir.
 Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
