Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine
oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.
WARNING - Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out
tires should be replaced as
soon as possible. For further
information and tread limits,
refer to "Tires and wheels" in
chapter 7.
WARNING- Under/Over Inflated Tires
Always check the tires for prop-
er inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.

What to do in an emergency
Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the bat-
tery 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 vehicle with the discharged
battery.
If the cause of your battery discharg-ing is not apparent, you should haveyour vehicle checked by an author-ized Kia dealer.
Push-starting
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this chapter
for jump-starting.
WARNING - Tow starting
vehicle
Never tow a vehicle to start it
because the sudden surge for-
ward when the engine starts
could cause a collision with the
tow vehicle.
WARNING - Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative
terminal of the discharged bat-
tery. This can cause the dis-
charged battery to overheat and
crack, releasing battery acid.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1.Pull off the road and stop as soonas it is safe to do so.
2.Place the shift lever in P (automat- ic transaxle) and set the parking
brake. If the air conditioning is on,
turn it off.
3.If engine coolant is running out under the vehicle or steam is com-
ing out from underneath 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 cool-
ing 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 leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning had been in use, it is nor-
mal for cold water to be draining
from it when you stop).
5.If the water pump drive belt is bro- ken or engine coolant leaks, 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
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized Kia dealer for
assistance.
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized Kia
dealer.
WARNING - Under the hood
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts.
WARNING - Radiator cap
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.

It is possible that some tires, espe-
cially with larger punctures or dam-
age to the sidewall, cannot be sealed
completely.
Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle
is heavily loaded or if a trailer is in
use.
The Tire Mobility Kit is not designed
or intended as a permanent tire
repair method and is to be used for
one tire only.
This instruction shows you step by
step procedure to temporarily seal
the puncture.
Read the section "Notes on the safe
use of the Tire Mobility Kit".Notes on the safe use of the
Tire Mobility Kit
Park your car at the side of the
road so that you can work with the
Tire Mobility Kit away from moving
traffic.
To be sure your vehicle will not move, even when you're on fairly
level ground, always set your park-
ing brake.
Only use the Tire Mobility Kit for sealing/inflation passenger car
tires. Only punctured areas located
within the tread region of the tire
can be sealed using the tire mobil-
ity kit.
Do not use on motorcycles, bicy- cles or any other type of tires.
When the tire and wheel are dam- aged, do not use Tire Mobility Kit
for your safety.
Use of the Tire Mobility Kit may not be effective for tire damage larger
than approximately 6 mm (0.24 in).
Please contact the nearest Kia
dealership if the tire cannot be
made roadworthy with the Tire
Mobility Kit. Do not use the Tire Mobility Kit if a
tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit unattended while it is being used.
Do not leave the compressor run- ning for more than 10 min. at a time
or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below -
-30°C (22°F).
