Driving your vehicle
Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can
reduce fuel economy.
Fuel economy is less in crosswinds
and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - HEV system
off during motion
Never turn the HEV system off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will not
function properly without the HEV
system running. Instead, keep the
HEV system on and downshift to an
appropriate gear for engine braking
effect. In addition, turning off the
ignition while driving could engage
the steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

Driving your vehicle

Adjust your mirrors to reduce the glare
from other driver's headlights.
Keep your headlights clean and prop-
erly aimed on vehicles not equipped
with the automatic headlight aiming
feature. Dirty or improperly aimed
headlights will make it much more diffi-
cult to see at night.
Avoid staring directly at the headlights
of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.Driving in the rain
Rain and wet roads can make driving dan-
gerous, especially if you’re not prepared
for the slick pavement. Here are a few
things to consider when driving in the rain:
A heavy rainfall will make it harder to
see and will increase the distance need-
ed to stop your vehicle, so slow down.
Keep your windshield wiping equip-
ment in good shape. Replace your
windshield wiper blades when they
show signs of streaking or missing
areas on the windshield.
If your tires are not in good condition,
making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. Be sure your tires are in
good shape.
Turn on your headlights to make it eas-
ier for others to see you.
Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
If you believe you may have gotten
your brakes wet, apply them lightly
while driving until normal braking oper-
ation returns.
Keep the interior surface of the wind-
shield clean by wiping it with a clean
cloth and glass cleaner. This will help
reduce the tendency of the glass fog-
ging and also improve visibility.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be affected.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.

Driving your vehicle
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
heated key with care to avoid injury.
Use approved window washer
anti-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 instructions on the con-
tainer. Window washer 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.
Don't let your parking brake
freeze
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 temporar-
ily while you put the shift lever in P (auto-
matic transaxle) or in first and block the
rear wheels so the vehicle cannot roll.
Then release the parking brake.
Don't let ice and snow accumu-
late underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.
Carry emergency equipment
Depending on the severity of the weath-
er where you drive your car, you should
carry appropriate emergency equipment.
Some of the items you may want to carry
include tire chains, tow straps or chains,
flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,
etc.

ROAD WARNING
Hazard warning flasher
The hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle.It should be used whenever emergency
repairs are being made or when the vehi-
cle is stopped near the edge of a road-
way.
Depress the flasher switch with the
engine start/stop button in any position.
The flasher switch is located in the cen-
ter console switch panel. All turn signal
lights will flash simultaneously.
• The hazard warning flasher operates
whether your vehicle is running or not.
The turn signals do not work when the
hazard flasher is on.
Care must be taken when using the
hazard warning flasher while the vehi-
cle is being towed.
If the vehicle stalls at a crossroad
or crossing
If the vehicle stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the vehi-
cle 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 accelerator pedal
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 con-
trol. 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 divid-
ed highway, do not park in the median
area between the two traffic lanes.

You may not be able identify a low
tire by simply looking at it. Always
use a good quality tire pressure
gauge to measure the tire's inflation
pressure. Please note that a tire that
is hot (from being driven) will have a
higher pressure measurement than a
tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.This device complies with Part 15
of the FCC rules.
Operation is subject to the following
two conditions:
1.This device may not cause harmful
interference, and
2.This device must accept any inter-
ference received, including inter-
ference that may cause undesired
operation.
CAUTION
Do not use any tire sealant
except the Tire Mobility Kit
approved by HYUNDAI if your
vehicle is equipped with a Tire
Pressure Monitoring System.
The liquid sealant can damage
the tire pressure sensors.
WARNING - Protecting
TPMS
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may interfere with the
system's ability to warn the driv-
er of low tire pressure condi-
tions and/or TPMS malfunctions.
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may void the warranty
for that portion of the vehicle.
WARNING- TPMS
The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually and with
light force, and slowly move to
a safe position off the road.
WARNING
Changes or modifications not
expressly approved by the party
responsible for compliance
could void the user’s authority
to operate the equipment.

Maintenance
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
Use only a mild soap or neutral deter-
gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high-
speed car wash brushes.
Do not use any cleaners containing
acid or acid detergents. It may damage
and corrode the aluminum wheels
coated with a clear protective finish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we produce 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 corrosion
on your car are:

allowed to accumulate underneath the
car.
Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.WARNING
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 for-
ward speed.
CAUTION
If the under cover is opened while
driving, water or materials rusting
the engine room may enter the
engine room. It may result in the
damage of Hybrid system.
