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.

The TPMS Malfunction Indicator
may illuminate after blinking for
one minute if the vehicle is near
electric power supply cables or
radio transmitters such as police
stations, government and public
offices, broadcasting stations,
military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow
chains are used or electronic
devices such as computers, charg-
ers, remote starters, navigation,
etc. This may interfere with normal
operation of the TPMS.
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.
The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire or
the flat tire is replaced with the spare
tire, the Low Tire Pressure Telltale
will remain on. Also, the TPMS
Malfunction Indicator will illuminate
after blinking for one minute if the
vehicle is driven at speed above 15.5
mph (25 km/h) for approximately 20
minutes.Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure Telltale and
TPMS Malfunction Indicator will go
off within a few minutes of driving.
If the indicators do not extinguish
after a few minutes, please visit an
authorized HYUNDAI dealer.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem (except for
the spare tire). You must use TPMS
specific wheels. It is recommended
that you always have your tires serv-
iced by an authorized HYUNDAI
dealer.
You may not be able to identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gauge to measure. Please
note that a tire that is hot (from being
driven) will have a higher pressure
measurement than a tire that is cold.
NOTICE
Never use a puncture-repairing
agent not approved by
HYUNDAI dealer to repair and/
or inflate a low pressure tire.
Tire sealant not approved by
HYUNDAI dealer may damage
the tire pressure sensor.

Maintenance
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. "Cold tires" means the
vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Warm tires normally exceed recom-
mended cold tire pressures by 4 to 6
psi (28 to 41 kPa). Do not release air
from warm tires to adjust the pres-
sure or the tires will be under-inflat-
ed. For recommended inflation pres-
sure, refer to "Tire and Wheels" in
chapter 8.Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-
ods at high speeds.

Exterior Care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label.
High-pressure washing
When using high-pressure wash-
ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers)or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
Finish maintenance
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign
materials. Make sure the drain holes
in the lower edges of the doors and
rocker panels are kept clear and
clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain
water may not completely remove all
these deposits. A mild soap, safe for
use on painted surfaces, should be
used. After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
WARNING

7-80
Maintenance
Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end
of each winter. Pay special attention
to these areas because it is difficult
to see all the mud and dirt. It will do
more harm than good to wet down
the road grime without removing it.
The lower edges of doors, rocker
panels, and frame members have
drain holes that should not be
allowed to clog with dirt; trapped
water in these areas can cause rust-
ing.
Aluminum wheel maintenance
The aluminum wheels are coated with
a clear protective finish.
Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, HYUNDAI produces cars
of the highest quality. However, this is
only part of the job. To achieve the
long-term corrosion resistance your
vehicle can deliver, the owner’s
cooperation and assistance is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
Road salt, dirt and moisture that is allowed to accumulate underneath
the vehicle.
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
WARNING
Do not use abrasive cleaner,
polishing compound, solvent,
or wire brushes on aluminum
wheels.
Clean the wheel when it has
cooled.
Use only a mild soap or neu-
tral detergent, and rinse thor-
oughly with water. Also, clean
the wheels after driving on
salted roads.
Do not wash the wheels with
high-speed car wash brushes.
Do not use any cleaners con-
taining acid or alkaline deter-
gents.
CAUTION

7-88
Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device.
To prevent damage to the catalytic
converter and to your vehicle, take
the following precautions:
Use only UNLEADED FUEL
for gasoline engines.
Do not operate the vehicle
when there are signs of
engine malfunction, such as
misfire or a noticeable loss of
performance.
Do not misuse or abuse the
engine. Examples of misuse
are coasting with the engine
off and descending steep
grades in gear with the engine
off.
Do not operate the engine at
high idle speed for extended
periods (5 minutes or more). (Continued)
CAUTION
(Continued)
Do not modify or tamper with
any part of the engine or
emission control system. All
inspections and adjustments
must be made by an author-
ized HYUNDAI dealer.
Avoid driving with an
extremely low fuel level.
Running out of fuel could
cause the engine to misfire,
damaging the catalytic con-
verter.
