What to do in an emergency
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, we recommend
that you have your vehicle checked
by an authorized HYUNDAI dealer.
Push-starting
Vehicles equipped with automatic
transmission cannot be push-start-
ed.
Follow the directions in this section
for jump-starting.CAUTION - Battery
cables
If you jump start the discharged
battery in the trunk compart-
ment, do not connect the
jumper cable from the negative
terminal of the booster battery
to the negative terminal of the
discharged battery. This can
cause the discharged battery to
overheat and crack, releasing
battery acid.
Connect the jumper cable from
the negative terminal of the
booster battery to a solid, sta-
tionary or metallic point away
from the discharged battery.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you 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 soon
as it is safe to do so.
2.Place the shift lever in P and set
the parking brake. If the air condi-
tioning is on, turn it off.
3.If engine coolant is running out
under the vehicle or steam is com-
ing 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 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 satis-
factory, check for coolant leaking
from the radiator, hoses or under
the vehicle. (If the air conditioning
had been in use, it is normal for
cold water to be draining from it
when you stop).
5.If the water pump drive belt is bro-
ken or engine coolant is leaking
out, we recommend that you 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
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,
we recommend that you call an
authorized 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 pre-
vent injury.
CAUTION
• Serious loss of coolant indi-
cates there is a leak in the
cooling system and we recom-
mend that the system be
checked as soon as possible
by an authorized HYUNDAI
dealer.
• When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
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.

TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alter-
nate tires or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMS
malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replace-
ment or alternate tires and wheels
allow the TPMS to continue to func-
tion properly.
✽NOTICE
If any of the below happens, we rec-
ommend that the system be checked
by an authorized HYUNDAI dealer.
1.The low tire pressure telltale/
TPMS malfunction indicator does
not illuminate for 3 seconds when
the ignition switch is turned to the
ON or engine is running.
2. The TPMS malfunction indicator
remains illuminated after blinking
for approximately 1 minute.
3. The Low tire pressure position
telltale remains illuminated.
Low tire pressure
telltale
Low tire pres-
sure position
telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The low tire
pressure position telltale light will
indicate which tire is significantly
under-inflated by illuminating the cor-
responding position light.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 a
spare tire.
If you drive the vehicle for about 10
minutes at speeds above 25 km/h
after replacing the low pressure tire
with the spare tire, the below will
happen:
• The TPMS malfunction indicator
may blink for approximately 1
minute and then remain continu-
ously illuminated because the
TPMS sensor is not mounted on
the spare wheel.

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
equipment. Use wheel lift or
flatbed equipment.
CAUTION
Failure to place the shift lever in
N (Neutral) may cause internal
damage 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 projections on the sur-
face of the ground.
We recommend that you take
your vehicle to an authorized
HYUNDAI dealer by towing the
vehicle and have the system
checked. You should tow the
vehicle as the picture.
