IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in P 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 coming out
from 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 cooling fan is operat-
ing. 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 leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning 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 broken
or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If over-
heating happens again, call an author-
ized HYUNDAI 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 prevent injury.
WARNING
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.
CAUTION
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
HYUNDAI dealer.

Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly.
✽NOTICE
If the TPMS, Low Tire Pressure tell-
tale do not illuminate for 3 seconds
when the ignition switch is turned to
the ON position or engine is run-
ning, or if they remain illuminated
after coming on for approximately 3
seconds, take your car to your near-
est authorized HYUNDAI dealer
and have the system checked.
Low tire pressure tell-
tale
Low tire pressure posi-
tion telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated, one or more of your tires is
significantly under-inflated. The low
tire pressure position telltale (supple-
mental) will indicate which tire is sig-
nificantly under-inflated by illuminat-
ing the corresponding position on the
LCD screen (if equipped).
If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver’s side cen-
ter pillar outer panel. If you cannot
reach a service station or if the tire
cannot hold the newly added air,
replace the low pressure tire with the
spare tire.The Low Tire Pressure and Position
telltale will remain on until you have
the low pressure tire repaired and
replaced on the vehicle.
✽NOTICE
The spare tire is not equipped with a
tire pressure sensor.
CAUTION
In winter or cold weather, the
low tire pressure telltale may be
illuminated if the tire pressure
was adjusted to the recom-
mended tire inflation pressure
in warm weather. It does not
mean your TPMS is malfunction-
ing because the decreased tem-
perature leads to a proportional
lowering of tire pressure.
When you drive your vehicle
from a warm area to a cold area
or from a cold area to a warm
area, or the outside temperature
is greatly higher or lower, you
should check the tire inflation
pressure and adjust the tires to
the recommended tire inflation
pressure.

IF YOU HAVE A FLAT TIRE
Jack and tools
The jack, jack handle, and wheel lug
nut wrench are stored in the luggage
compartment. Pull up the luggage
box cover to reach this equipment.
(1) Jack handle
(2) Jack
(3) Wheel lug nut wrench
Jacking instructions
The jack is provided for emergency
tire changing only.
To prevent the jack from “rattling”
while the vehicle is in motion, store it
properly.
Follow jacking instructions to reduce
the possibility of personal injury.
OVI069004L
(Continued)
• Be sure to use the correct
front and rear jacking posi-
tions on the vehicle; never
use the bumpers or any other
part of the vehicle for jacking
support.
• The vehicle can easily roll off
the jack causing serious
injury or death.
• Do not get under a vehicle
that is supported by a jack.
• Do not start or run the engine
while the vehicle is on the
jack.
• Do not allow anyone to remain
in the vehicle while it is on the
jack.
• Make sure any children pres-
ent are in a secure place away
from the road and from the
vehicle to be raised with the
jack.
WARNING- Changing tires
• Never attempt vehicle repairs
in the traffic lanes of a public
road or highway.
• Always move the vehicle com-
pletely off the road and onto
the shoulder before trying to
change a tire. The jack should
be used on level firm ground.
If you cannot find a firm, level
place off the road, call a tow-
ing service company for
assistance.

What to do in an emergency
When towing your vehicle in an emer-
gency without wheel dollies :
1. Set the engine start/stop button in the
ACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.
OVI069014
OVI069013
CAUTION
• Do not tow the vehicle with the
rear wheels on the ground as this
may cause damage to the vehicle.
• Do not tow with sling-type equip-
ment. Use wheel lift or flatbed
equipment.
CAUTION
Failure to place the shift lever in N
(Neutral) may cause internal dam-
age to the transmission.
CAUTION
If the ECS malfunction indicator
illuminates when there is no air in
the suspension, the vehicle height
will be very lower, so do not drive to
protect the vehicle from the projec-
tions on the surface of the ground.
Take your vehicle to an authorized
HYUNDAI dealer by towing the vehi-
cle and have the system checked.
You should tow the vehicle as the
picture.

• Use a towing strap less than 5 m (16
feet) 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.
Emergency towing precautions
• Place the engine start/stop button in
ACC so the steering wheel isn’t locked.
• Place the transmission shift lever in N
(Neutral).
• Release the parking brake.
• 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.WARNING
Use extreme caution when towing
the vehicle.
• Avoid sudden starts or erratic
driving maneuvers which would
place excessive stress on the
emergency towing hook and tow-
ing cable or chain. The hook and
towing cable or chain may break
and cause serious injury or dam-
age.
• If the disabled vehicle is unable
to be moved, do not forcibly con-
tinue the towing. Contact an
authorized HYUNDAI dealer or a
commercial tow truck service for
assistance.
• Tow the vehicle as straight ahead
as possible.
• Keep away from the vehicle dur-
ing towing.
