WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
car into D (Drive) or R (Reverse).
WARNING
When you intend to park or stop
the vehicle with the engine on, be
careful not to depress the acceler-
ator pedal for a long period of
time. It may overheat the engine or
exhaust system and cause a fire.
When you make a sudden stop or turn the steering wheel rapidly,
loose objects may drop on the
floor and it could interfere with
the operation of the foot pedals,
possibly causing an accident.
Keep all things in the vehicle
safely stored.
If you do not focus on driving, it may cause an accident. Be care-
ful when operating controls while
driving such as the audio or
heater. It is the responsibility of
the driver to always drive safely.

Driving your vehicle
If the parking brake does not release or
does not release all the way, have the
system checked by an authorized
HYUNDAI dealer.Check the brake warning light by pressing
the engine start/stop button ON (do not
start the engine). This light will be illumi-
nated when the parking brake is applied
with the engine start/stop button in the
START or ON position.
Also, the brake warning light may illumi-
nate for a second even though the park-
ing brake is released at the moment the
engine start/stop button is pressed to the
ON position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on after
the parking brake is released while the
hybrid system is in READY state, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.If at all possible, cease driving the vehicle
immediately. If that is not possible, use
extreme caution while operating the vehi-
cle and only continue to drive the vehicle
until you can reach a safe location or
repair shop.
WARNING
To prevent unintentional move-
ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in P (Park) for automatic
transaxle equipped vehicles.
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.
W-75
WARNING
It is normal for the brake warninglight to illuminate temporarily
when the brake is depressed
repeatedly and go out after a few
seconds when the brake is no
longer depressed. However, if the
brake warning light turns on, this
may be a sign of a malfunctioning
brake system and could cause
the braking distance to increase.
Have your system checked if the brake warning light remains on. A
malfunctioning brake system
could result in a vehicle accident
and serious injury or death.

Driving your vehicle
✽
✽NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic stability control (ESC)
The Electronic Stability control (ESC)
system is designed to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies the
brakes at individual wheels and
intervenes in the engine management
system to stabilize the vehicle.
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev-er, your regular brakes will worknormally.
The ABS warning light will stay on for approximately 3 seconds afterthe engine start/stop button is ON.During that time, the ABS will gothrough self-diagnosis and thelight will go off if everything is nor-mal. If the light stays on, you mayhave a problem with your ABS.Contact an authorized HYUNDAIdealer as soon as possible.
CAUTION
When you drive on a road having poor traction, such as an icy road,and operate your brakes continu-ously, the ABS will be active con-tinuously and the ABS warning light may illuminate. Pull your carover to a safe place and stop theengine.
Restart the engine. If the ABS warning light is off, then yourABS system is normal.Otherwise, you may have a prob-lem with the ABS. Contact anauthorized HYUNDAI dealer assoon as possible.

The Electronic Stability Control (ESC)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESC will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESC is active.
✽ ✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Control System is functioning properly.

for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).
you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem.WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability control
(ESC) will not prevent accidents.
Excessive speed in turns, abrupt
maneuvers and hydroplaning on
wet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding maneuvers that
cause the vehicle to lose traction.
Even with ESC installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.

Good braking practices
Check to be sure the parking brake isnot engaged and that the parking brake
indicator light is out before driving away. Driving through water may get the
brakes wet. They can also get wet when
the car is washed. Wet brakes can be
dangerous! Your car will not stop as
quickly if the brakes are wet. Wet brakes
may cause the car to pull to one side.
To dry the brakes, apply the brakes light-
ly until the braking action returns to nor-
mal, taking care to keep the car under
control at all times. If the braking action
does not return to normal, stop as soon
as it is safe to do so and call an author-
ized HYUNDAI dealer for assistance.
Don't coast down hills with the car out of gear. This is extremely hazardous. Keep
the car in gear at all times, use the
brakes to slow down, then shift to a
lower gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake pedal while driv-
ing can be dangerous because it can
result in the brakes overheating and los-
ing their effectiveness. It also increases
the wear of the brake components.
If a tire goes flat while you are driving, apply the brakes gently and keep the car
pointed straight ahead while you slow
down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe place. If your vehicle is equipped with an auto-
matic transaxle, don't let your vehicle
creep forward. To avoid creeping for-
ward, keep your foot firmly on the brake
pedal when the vehicle is stopped.
Use caution when parking on a hill. Firmly engage the parking brake and
place the shift lever in P position. If your
vehicle is facing downhill, turn the front
wheels into the curb to help keep the
vehicle from rolling. If your vehicle is fac-
ing uphill, turn the front wheels away
from the curb to help keep the vehicle
from rolling. If there is no curb or if it is
required by other conditions to keep the
vehicle from rolling, block the wheels.
Under some conditions your parking brake can freeze in the engaged posi-
tion. 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 that the
parking brake may freeze, apply it only
temporarily while you put the gear
selector lever in P positionand block
the rear wheels so the vehicle cannot
roll. Then release the parking brake.
Do not hold the vehicle on an hill with the accelerator pedal. This can cause
the transaxle to overheat. Always use
the brake pedal or parking brake.
WARNING
Whenever you leave or park yourvehicle, always firmly set the
parking brake as far as possible
and fully engage the vehicle's
transaxle into the P (Park) posi-
tion. If the parking brake is not
fully engaged, the vehicle may
move inadvertently and injure
yourself and others.
Always have the parking brake fully engaged when parking to
avoid inadvertent movement of
the vehicle which can injure
occupants or pedestrians.
CAUTION
Do not depress the brake pedal con-tinuously without READY status. Thebattery may be discharged.

Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
miles (kilometers) you can get from a gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-
tion. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption. Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequent
maintenance is required (see section 7
for details).
Keep your car clean. For maximum service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-
sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
ECONOMICAL OPERATION

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.
Don't place foreign objects or
materials in the engine compart-
ment
Placement of foreign objects or
materials which prevent cooling of
the engine, in the engine compart-
ment, may cause a failure or com-
bustion. The manufacturer is not
responsible for the damage caused
by such placement.

What to do in an emergency
1. If your vehicle has an automatictransaxle, be sure the shift lever is in N
(Neutral) or P (Park) and the emer-
gency brake is set.
2. Check the 12 volt 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 operate the
starter, the battery is discharged.
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 engine start/stop button inthe LOCK position, check all connec-
tors 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.
IF THE VEHICLE WILL NOT START
WARNING
If the vehicle will not start, do not
push or pull the vehicle to start it.
This could result in a collision or
cause other damage. In addition,
push or pull starting may cause the
catalytic converter to be over-
loaded and create a fire hazard.
