Features of your vehicle
Auto defogging system (Only for automatic climate controlsystem, if equipped)
Auto defogging reduces the possibility of
fogging up the inside of the windshield by
automatically sensing the moisture of
inside the windshield.
The auto defogging system operates
when the AUTO mode is on. This indicator illuminates
when the auto defogging
system senses the moisture
of inside the windshield and
operates.
If more moisture is in the vehicle, higher
steps operate as follow.
Step 1 : Operating the air conditioning
Step 2 : Outside air position
Step 3 : Blowing air flow toward the wind- shield
Step 4 : Increasing air flow toward the windshield
If your vehicle is equipped with the auto
defogging system, it is automatically acti-
vated when the conditions are met.
However, if you would like to cancel the
auto defogging system, press the front
defroster button 4 times within 2 seconds
while pressing the AUTO button. The
indicator will blink 3 times to notify you
that the system is cancelled. To use the
auto defogging system again, follow the
procedures mentioned above.
If the battery has been disconnected or
discharged, it resets to the auto defog-
ging status.
✽ ✽ NOTICE
If the A/C off is manually selected while
the auto defogging system is on, the auto
defogging indicator will blink 3 times to
give notice that the A/C off can not be
selected.

Jump starting procedure 1. Make sure the booster battery is 12-voltand that its negative terminal is grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles to touch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration. First
connect one end of a jumper cable to the
positive terminal of the discharged bat-
tery (1), then connect the other end to the
positive terminal on the booster battery
(2). Proceed to connect one end of the
other jumper cable to the negative termi-
nal of the booster battery (3), then the
other end to a solid, stationary, metallic
point (for example, the engine lifting
bracket) away from the battery (4). Do not
connect it to or near any part that moves
when the engine is cranked.
Do not allow the jumper cables to contact
anything except the correct battery termi-
nals or the correct ground. Do not lean
over the battery when making connec-
tions.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 vehi-
cle with the discharged battery.
If the cause of your battery discharging isnot apparent, you should have your vehi-cle checked by an authorized HYUNDAIdealer.
Push-starting
Your manual transaxle-equipped vehicle
should not be push-started because it
might damage the emission control sys-
tem. Vehicles equipped with automatic
transaxle cannot be push-started. Follow
the directions in this section for jump-
starting.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.
CAUTION- Battery cables
Do not connect the jumper cable fromthe negative terminal of the booster battery to the negative terminal of thedischarged battery. This can cause the discharged battery to overheatand crack, releasing battery acid.
CAUTION-AGM battery
(if equipped)
Absorbent Glass Matt (AGM) bat- teries are maintenance-free andshould only be serviced by anauthorized HYUNDAI dealer. For charging your AGM battery, useonly fully automatic batterychargers that are specially devel-oped for AGM batteries.
When replacing the AGM battery, use only the HYUNDAI genuinebattery for the ISG system.
Do not open or remove the cap on top of the battery. This may causeleaks of internal electrolyte thatcould result in severe injury.
If the AGM battery is reconnected or replaced, ISG function will notoperate immediately.
If you want to use the ISG func-tion, the battery sensor needs tobe calibrated for approximately 4hours with the ignition off.

What to do in an emergency
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
replacement or alternate tires and
wheels allow the TPMS to continue
to function properly.
✽ ✽NOTICE
Take your vehicle to the nearest
authorized HYUNDAI dealer and
have the system checked if any of
the below happens:
1.The low tire pressure telltale/
TPMS malfunction indicator and
low tire pressure position telltale
do not illuminate.
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 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 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. After you replace the low pressure
tire with the spare tire, one of the fol-
lowing will happen:
The TPMS malfunction indicator
may blink for approximately 1
minute and then remain continuous-
ly illuminated because the TPMS
sensor is not mounted on the spare
wheel. (changed tire equipped with
a sensor not in the vehicle)
The TPMS malfunction indicator will remain continuously illuminated
while driving because the TPMS
sensor is not mounted on the spare
wheel. (changed tire equipped with
a sensor in the vehicle)

TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS malfunction indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tire Pressure
Monitoring System. If the system is
able to correctly detect an under infla-
tion warning at the same time as sys-
tem failure then the TPMS malfunc-
tion indicator remains illuminated
after blinking for approximately 1
minute and the low tire pressure posi-
tion telltale will illuminate e.g. if Front
Left sensor fails, the TPMS malfunc-
tion indicator remains illuminated
after blinking for approximately 1
minute, but if the Front Right, Rear
Left, or Rear Right tire is under-inflat-
ed, the low tire pressure position tell-
tales may illuminate together with the
TPMS malfunction indicator.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible to determine the cause
of the problem.
WARNING - Low pressure damage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tires can cause the tires to
overheat and fail.CAUTION
In winter or cold weather, the low tire pressure telltale mayilluminate if the tire pressurewas adjusted to the recom-mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction-ing because the decreased tem-perature leads to a proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, youshould check the tire inflationpressure and adjust the tires tothe recommended tire inflationpressure.

What to do in an emergency
Changing a tire with TPMS
If you have a flat tire, the low Tire
Pressure and Position telltales will
come on. Have the flat tire repaired
by an authorized HYUNDAI dealer
as soon as possible or replace the
flat tire with the spare tire.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended that you always have
your tires serviced by an authorized
HYUNDAI dealer.After you replace the low pressure
tire with the spare tire, one of the fol-
lowing will happen:
The TPMS malfunction indicator
may blink for approximately 1
minute and then remain continuous-
ly illuminated because the TPMS
sensor is not mounted on the spare
wheel. (changed tire equipped with
a sensor not in the vehicle)
The TPMS malfunction indicator will remain continuously illuminated
while driving because the TPMS
sensor is not mounted on the spare
wheel. (changed tire equipped with
a sensor in the vehicle)CAUTION
The TPMS malfunction indica- tor may blink for approximate-ly 1 minute and then remaincontinuously illuminated if thevehicle is moving around elec-tric power supply cables orradios transmitter such as atpolice stations, governmentand public offices, broadcast-ing stations, military installa-tions, airports, or transmittingtowers, etc. This can interferewith normal operation of theTire Pressure MonitoringSystem (TPMS).
The TPMS malfunction indica- tor may blink for approximate-ly 1 minute and then remaincontinuously illuminated ifsnow chains are used or someseparate electronic devicessuch as notebook computer,mobile charger, remote starteror navigation etc., are used inthe vehicle. This can interferewith normal operation of theTire Pressure MonitoringSystem (TPMS).
CAUTION
Never use a puncture-repairingagent not approved by HYUNDAIto repair and/or inflate a lowpressure tire. The tire sealant notapproved by HYUNDAI may dam-age the tire pressure sensor.
The sealant on the tire pressuresensor and wheel shall be elem-inated when you replace the tirewith a new one.
