Check spark plugs and ignitionsystem
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
Use approved window washeranti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.
Do not let your parking brakefreeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear selector lever in P
and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not let ice and snow accu-mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects ormaterials in the engine com-partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

What to do in an emergency
If you Have a Flat Tire While
Driving
If a tire goes flat while you are driving:
Take your foot off the acceleratorpedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake care-
fully 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.
When the vehicle is stopped, press the hazard warning flasher button,
move the shift lever into P(Park),
and apply the parking brake, and
place the ignition switch in the
LOCK/OFF position.
Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tire, follow the instructions provided later in
this chapter.
If the Engine Doesn’t Turn
Over or Turns Over Slowly
Be sure the shift lever is in N
(Neutral) or P (Park). The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
Check the battery connections to be sure they are clean and tight.
Turn on the interior light. If the light dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
If the Engine Turns Over
Normally but Doesn’t Start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized HYUNDAI dealer.

Check Tire Pressure
You can check the tire pressure inthe Information Mode on the clus-
ter.
Refer to the "User Settings
Mode" section in chapter 3.
Tire pressure is displayed after a few minutes of driving after initial
engine start up.
If tire pressure is not displayed when the vehicle is stopped, "Drive
to display" message will appear.
After driving, check the tire pres-
sure. The displayed tire pressure values
may differ from those measured
with a tire pressure gauge.
You can change the tire pressure unit in the User Settings Mode on
the cluster.
- psi, kpa, bar (Refer to the "User
Settings Mode" section in
chapter 3).

13. Use the wheel lug nut wrench totighten the lug nuts in the order
shown. Double-check each lug
nut until they are tight. After
changing tires, have an author-
ized HYUNDAI dealer tighten the
lug nuts to their proper torque as
soon as possible. The wheel lug
nut should be tightened to
79~94 lbf
ft (11~13 kgfm). If you have a tire gauge, check the
tire pressure (see "Tires and
Wheels" in chapter 8 for tire pressure
instructions.). If the pressure is lower
or higher than recommended, drive
slowly to the nearest service station
and adjust it to the recommended
pressure. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced,
air may leak from the tire. If you lose
a valve cap, buy another and install it
as soon as possible. After changing
tires, secure the flat tire and return
the jack and tools to their proper stor-
age locations.
Check the tire pressure as soon
as possible after installing a spare
tire. Adjust it to the recommended
pressure.
If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.
NOTICE
OLF064013
■Rear
Your vehicle has metric threads
on the studs and lug nuts. Make
certain during tire changing
that the same nuts that were
removed are reinstalled. If you
have to replace your lug nuts
make sure they have metric
threads to avoid damaging the
studs and ensure the wheel is
properly secured to the hub.
Consult an authorized
HYUNDAI dealer for assistance.

What to do in an emergency
5. Insert the sealant bottle into thehousing (4) of the compressor so
that the bottle is upright.
6. Ensure that the compressor is switched off, position 0. 7. Plug the compressor power cord
(3) into the vehicle power outlet.
8. With the ignition switch in the ON position, switch on the compres-
sor and let it run for approximately
5~7 minutes to fill the sealant up
to proper pressure. (refer to the
Tire and Wheels, chapter 8). The
inflation pressure of the tire after
filling is unimportant and will be
checked/corrected later.
Be careful not to overinflate the
tire and stay away from the tire
when filling it.

Precautions
Inadequate, incomplete or insuffi-
cient servicing may result in opera-
tional problems with your vehicle that
could lead to vehicle damage, an
accident, or personal injury. This
chapter provides instructions only for
the maintenance items that are easy
to perform. Several procedures can
be done only by an authorized
HYUNDAI dealer with special tools.
Your vehicle should not be modified
in any way. Such modifications may
adversely affect the performance,

Maintenance
Valve Clearance (if equipped)
Inspect for excessive valve noise
and/or engine vibration and adjust if
necessary. Have an authorized
HYUNDAI dealer perform the opera-
tion.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic Transmission Fluid
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized HYUNDAI dealer in accor-
dance to the scheduled maintenance
at the beginning of this chapter.
Automatic transmission fluid
color is basically red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal
condition and you should not
judge the need to replace the fluid
based upon the changed color.
Ecoshift dual clutch transmis-
sion Fluid
Inspect the Ecoshift dual clutch
transmission fluid according to the
maintenance schedule.
NOTICE
The use of a non-specified fluid
could result in transmission
malfunction and failure. Use
only the specified automatic
transmission fluid (refer to
"Recommended Lubricants and
Capacities" in chapter 8).
