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
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 the coolant temperature
gauge on the instrument cluster to
make sure the coolant tempera-
ture is sufficiently cooled down. 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 warning light illumination,
engine coolant leakage, or cooling
fan malfunction are found, stop the
vehicle the earliest. Then, call the
nearest authorized 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 pre-
vent injury.

6. If you cannot find the cause of theoverheating, 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
WARNING
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.

ENGINE MAINTENANCE MODE(FOR PLUG-IN HYBRID)
Starting Engine Maintenance
Mode
To prevent damage of the engine
lubrication system when the engine
has not been started for a long time:
- When the engine is started after 5
weeks of being turned off, the
engine maintenance mode will
operate.
- When the engine maintenance mode is operated, HEV mode will
be kept on after the engine is ON
and the above message will be dis-
played on the cluster. If you press the HEV switch to shift
EV mode during engine mainte-
nance mode, the above message will
appear due to priority of the engine
maintenance mode.
Stopping Engine Maintenance
Mode
The engine will automatically stop
after sufficient heating. If the engine
is turned OFF without sufficient heat-
ing, the engine maintenance mode
will be operated once more.
