Driving your vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
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
result in overheating of the engine.
WARNING- Under/overinflated tires
Always check the tires for proper
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.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
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 8.

What to do in an emergency
Jump starting procedure
1. Make sure the booster battery is12-volt and that its negative termi-
nal is grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles
to come in contact.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illus-
tration. First connect one end of a
jumper cable to the positive termi-
nal of the discharged battery (1),
then connect the other end to the
positive terminal of 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, sta-
tionary, 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.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, directly. This can cause the
discharged battery to overheat
and crack and/or cause degra-
dation.
Connect the jumper cable from
the negative terminal of the
booster battery to the chassis
ground in the engine room.WARNING- Electrolyte
Do not charge or discharge arbitrarily. It may lead to fault,
electric shock or burns.
Do not damage the battery in any way, including dropping it,
impacting it, or piercing it with
a sharp object. It may cause
electrolyte leakage or fire.
Breakdown of the unit may lead to electrolyte leakage or
flammable gas generation. If
this occurs, contact an author-
ized Kia dealer immediately.
If electrolyte leaks out, avoid contact with eyes, skin or
clothes. In event of accident,
flush with water and get med-
ical help immediately.
Do not place near open flame or incinerate. It may lead to
fire or explosion.
Keep battery out of reach of children or animals.
Keep the battery away from moisture and liquid. Do not
touch or use if liquids have
been spilled on the battery.
WARNING- Sulfuric acid
risk
Automobile batteries contain
sulfuric acid. When jump start-
ing your vehicle, be careful not
to get sulfuric acid on yourself,
your clothing, or on the vehicle.
This acid is poisonous and
highly corrosive.

What to do in an emergency
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. Turn on the emergency warningflasher and stop in a safe place.
Move the shift lever to P (Park)
and engage the parking brake.
2. If hot steam does not come out from the engine room, carefully
open the engine room and check
whether the water pump connec-
tor is properly engaged. If the con-
nector is not properly engaged,
stop the engine immediately and
properly engage the connector.
Then, turn the engine on.
3. Turn on the air conditioner. 4. If the “HEV Warning” light turns on
in the driver instrument cluster, or
engine coolant or hot steam emits
from the engine coolant filler, stop
the engine immediately. Then, call
the nearest authorized Kia dealer
for assistance. If the “Engine
Warning” light remains illuminated
or the engine coolant is not flowing
out, keep the engine running.
Open the engine hood for ventila-
tion to help cool down the engine. 5. Check whether the engine coolant
temperature is low enough by
checking its temperature. If the
engine coolant level is low, please
check the connecting parts
between the radiator hose, heater
hose, and water pump for any signs
of leakage. When there is no sign of
leakage, please refill the engine
coolant. If causes and signs of
engine overheating such as warn-
ing light illumination, engine coolant
leakage, or cooling fan malfunction
are found, stop the vehicle the ear-
liest. Then, call the nearest author-
ized Kia dealer for assistance.
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 to pre-
vent injury.
WARNING- Radiator Cap
Do not remove the
radiator cap when the
engine is hot. This
can allow coolant to
blow out of the open-
ing and cause seri-
ous burns.

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 over heating happens again,
call the nearest authorized Kia
dealer for assistance.✽ ✽NOTICE
Serious loss of coolant indicates
there is a leak in the cooling system
and should be checked as soon as
possible by an authorized Kia dealer.
CAUTION
When the engine overheats from
low engine coolant, suddenlyadding engine coolant maycause cracks in the engine. Toprevent damage, add enginecoolant slowly in small quantities

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
Mobility 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 0.16 in. (4
mm).
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 -
22°F (-30°C).
WARNING
Do not use the Tire sealant after
the sealant has expired (i.e.
past the expiration date on the
sealant container). This can
increase the risk of tire failure.
CAUTION
When repairing a flat tire withthe Tire Mobility Kit (TMK),quickly remove the sealant onthe tire pressure sensor andwheel. When installing therepaired tire and wheel, tightenthe wheel nut to a torque valueof 11 ~ 13 kgf·m.
WARNING - Sealant
Keep out of reach of children.
Avoid contact with eyes.
Do not swallow.
