Driving your vehicle
Turn signals when towing a trailer
When you tow a trailer, your vehicle
has to have a different turn signal
flasher and extra wiring. The green
arrows on your instrument panel will
flash whenever you signal a turn or
lane change. Properly connected,
the trailer lights will also flash to alert
other drivers you're about to turn,
change lanes, or stop.
When towing a trailer, the green
arrows on your instrument panel will
flash for turns even if the bulbs on the
trailer are burned out. Thus, you may
think drivers behind you are seeing
your signals when, in fact, they are
not. It's important to check occasion-
ally to be sure the trailer bulbs are still
working. You must also check the
lights every time you disconnect and
then reconnect the wires.
Do not connect a trailer lighting sys-
tem directly to your vehicle's lighting
system. Use only an approved trailer
wiring harness.
An authorized HYUNDAI dealer can
assist you in installing the wiring har-
ness.
Driving on grades
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don’t shift
down, you might have to use your
brakes so much that they would get
hot and no longer operate efficiently.
On a long uphill grade, shift down
and reduce your speed to around 45
mph (70 km/h) to reduce the possi-
bility of engine and transaxle over-
heating.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat build up and extend the life of
your transaxle.WARNING
Failure to use an approved trail-
er wiring harness could result
in damage to the vehicle electri-
cal system and/or personal
injury.

What to do in an emergency
IN CASE OF AN EMERGENCY WHILE DRIVING
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
If you have a flat tire while
driving
If a tire goes flat while you are driving:
1. Take your foot off the acceleratorpedal and let the car slow down
while driving straight ahead. Do
not apply the brakes immediately
or attempt to pull off the road as
this may cause a loss of control.
When the car has slowed to such
a speed that it is safe to do so,
brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
2. When the vehicle is stopped, turn on your emergency hazard flashers,
set the parking brake and put the
transaxle in P.
3. Have all passengers get out of the car. Be sure they all get out on the
side of the car that is away from
traffic.
4. When repairing a flat tire, follow the instruction provided later in
this section.
If engine stalls while driving
1. Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, contact
an authorized HYUNDAI dealer or
seek other qualified assistance.
✽ ✽NOTICE
If there was a check engine light and
loss of power or stall, it is best if safe
to do so to wait at least 10 seconds to
restart a vehicle after it stalls. This
may reset the car so it will no longer
run at low power (limp home) condi-
tion.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransaxle, be sure the shift lever is
in N (Neutral) or P (Park) and the
emergency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you oper-
ate the starter, the battery is dis-
charged.
4. Do not push or pull the vehicle to start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1. Check fuel level.
2. With the ignition switch in the LOCKposition, check all connectors at
ignition coils and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. If the engine still does not start, call an authorized HYUNDAI dealer or
seek other qualified assistance.
WARNING
If the engine will not start, do
not push or pull the vehicle to
start it. This could result in a
collision or cause other dam-
age. In addition, push or pull
starting may cause the catalytic
converter to be overloaded and
create a fire hazard.

What to do in an emergency
✽
✽NOTICE
If any of the below happens, have
the system checked by an authorized
HYUNDAI dealer.
1.The low tire pressure telltale/
TPMS malfunction indicator does
not illuminate for 3 seconds when
Engine Start/Stop button 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 position tell-
tale and tire pressure telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and warning massage 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 20
minutes at speeds above 15.5 mph
(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.

exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.

FUSES
A vehicle's electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 fuse panels, one
located in the driver's side panel bol-
ster, the other in the engine compart-
ment near the battery.
If any of your vehicle's lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted.
If the electrical system does not
work, first check the driver's side
fuse panel.
Always replace a blown fuse with
one of the same rating.
Before replacing an open fuse, dis-
connect the negative battery cable.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.✽ ✽ NOTICE
The actual fuse/relay panel label
may differ from equipped items.
