Driving your vehicle
Always be cautious for vehicles
with higher height or vehicles car-
rying loads that sticks out from the
back of the vehicle.
OFE058042
When using the Smart Cruise
Control take the following pre-
cautions:
If an emergency stop is nec-
essary, you must apply the
brakes. The vehicle cannot be
stopped at every emergency
situation by using the Smart
Cruise Control system.
Keep a safe distance accord-
ing to road conditions and
vehicle speed. If the vehicle to
vehicle distance is too close
during a high-speed driving, a
serious collision may result.
Always maintain sufficient
braking distance and deceler-
ate your vehicle by applying
the brakes if necessary.
The Smart Cruise Control sys-
tem cannot recognize a
stopped vehicle, pedestrians or
an oncoming vehicle. Always
look ahead cautiously to pre-
vent unexpected and sudden
situations from occurring.
WARNING Vehicles moving in front of
you with a frequent lane
change may cause a delay in
the system's reaction or may
cause the system to react to a
vehicle actually in an adjacent
lane. Always drive cautiously
to prevent unexpected and
sudden situations from occur-
ring.
Always be aware of the select-
ed speed and vehicle to vehi-
cle distance. The driver
should not solely rely on the
system but always pay atten-
tion to driving conditions and
control your vehicle speed.
The Smart Cruise Control sys-
tem may not recognize com-
plex driving situations so
always pay attention to driv-
ing conditions and control
your vehicle speed.
For your safety, please read
the owner's manual before
using the Smart Cruise
Control system.

Information
The ESC system (if equipped) must be
turned OFF before rocking the vehi-
cle.
If you are still stuck after rocking
the vehicle a few times, have the
vehicle pulled out by a tow vehicle
to avoid vehicle overheating, pos-
sible damage to the reduction
gear and tire damage. See
"Towing" in chapter 6.
Smooth Cornering
Avoid braking, especially when roads
are wet. Ideally, corners should
always be taken under gentle accel-
eration.
Driving at Night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
Slow down and keep more dis-
tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
Adjust your mirrors to reduce the
glare from other driver's head-
lamps.
Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
Avoid staring directly at the head-
lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
Slow down and allow extra follow-
ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
Turn OFF your Cruise Control. (if
equipped)
Replace your windshield wiper
blades when they show signs of
streaking or missing areas on the
windshield.
Be sure your tires have enough
tread. If your tires do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See "Tire Tread" in chapter 7.
Turn on your headlamps to make it
easier for others to see you.
Driving too fast through large pud-
dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
NOTICE
i

5-120
Driving your vehicle
If you believe your brakes may be
wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tire tread
decreases, refer to "Tire Tread" in
chapter 7.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Coolant and high voltage bat-
tery
Be sure to check both the coolant
level and the high voltage battery
level before driving.

5-122
Driving your vehicle
The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use regenera-
tive braking to the fullest extent.
Sudden brake applications on snowy
or icy roads may cause the vehicle to
skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without
first checking local, state and munici-
pal regulations for possible restric-
tions against their use.
Air cleaner filter (FCEV)
The snow may block the air cleaner
filter after driving the vehicle in heavy
snow when the ambient temperature
is below 50°F (10°C).
If a warning message "Air filter
blocked. Check filter or see user
manual" appears on LCD display
after turning off the vehicle, remove
the snow from the inside of the air
cleaner filter and turn on and off the
vehicle. If the warning message is
displayed again, the exhaust pipe
may be blocked. Then, move your
vehicle indoors and leave it inside
more than one day to defrost the
exhaust pipe.
If the warning message is displayed
again, have the vehicle checked by
an authorized HYUNDAI dealer.

Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.
WARNING

5-124
Driving your vehicle
When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.47 in
(12 mm) thick to prevent damage
to the chain's connection.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
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 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
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Do not 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 temporarily while
you shift to P (Park) and block the
rear wheels so the car cannot roll.
Then release the parking brake.
NOTICE

If you have a flat tire while
driving
If a tire goes flat while you are driv-
ing:
1. Take your foot off the accelerator
pedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause a loss of con-
trol. When the vehicle 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 medi-
an area between the two traffic
lanes.
2. When the vehicle is stopped, turn
on your emergency hazard flash-
ers, set the parking brake and shift
gear to the P(Park) position.
3. 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.
If the vehicle stalls while driv-
ing
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 vehicle again. If
your vehicle will not start, contact
an authorized HYUNDAI dealer. Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu-
lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw
to prevent full discharge. If vehicle
will not start, first try pressing the
12V Battery Reset switch (left side
of the steering wheel near the fuel
door open switch) to reconnect the
12V battery, but you must start
vehicle within 15 seconds of press-
ing the 12V Battery Reset switch.
After starting vehicle, operate the
vehicle safely outdoors in ready
mode stopped and/or drive it for 30
minutes total to charge the 12V
battery fully.
Check the fuel level and add fuel if
necessary.
Do not push or pull the vehicle to
start it.
If the vehicle still does not start, call
an authorized HYUNDAI dealer for
assistance.

What to do in an emergency
You may not be able identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gage to measure the tire's
inflation pressure. Please note that a
tire that is hot (from being driven) will
have a higher pressure measure-
ment 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.

i
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 with light
force, and slowly move to a
safe position off the road.
WARNING
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS)
components may interfere with
the system's ability to warn the
driver of low tire pressure con-
ditions and/or TPMS malfunc-
tions. Tampering with, modify-
ing, or disabling the Tire
Pressure Monitoring System
(TPMS) components may void

the vehicle.
WARNING

6-26
Emergency Towing
If towing is necessary, we recom-
mend you have it done by an author-
ized HYUNDAI dealer or a commer-
cial tow truck service.If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the front (or rear) of the
vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Always follow these emergency tow-
ing precautions:
• While depressing the brake pedal
shift to the N (Neutral) position and
turn the vehicle off. The POWER
button will be in the ACC position.
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force.
