NOTICE
• In sports mode, the driver must exe-
cute upshifts in accordance with road
conditions.
• In sports mode, only the 6 forward
gears can be selected. To reverse or
park the vehicle, move the shift lever
to the R (Reverse) or P (Park) position
as required.
• In sports mode, downshifts are made
automatically when the vehicle slows
down. When the vehicle stops, 1st gear
is automatically selected.
• In sports mode, when the engine rpm
approaches the red zone, the transaxle
will upshift automatically.
• To maintain the required levels of vehi-
cle performance and safety, the system
may not execute certain gearshifts
when the shift lever is operated.
• When driving on a slippery road, push
the shift lever forward into the +(up)
position. This causes the transaxle to
shift into the 2nd gear which is better
for smooth driving on a slippery road.
Push the shift lever to the -(down) side
to shift back to the 1st gear.
• When using sports mode, slow down
before shifting to a lower gear.
Otherwise, the lower gear may not be
engaged.
Shift lock system
For your safety, the automatic transaxle
has a shift lock system which prevents
shifting the transaxle from P (Park) into R
(Reverse) unless the brake pedal is
depressed.
To shift the transaxle from P (Park) into R
(Reverse):
1. Depress and hold the brake pedal.
2. Start the engine or turn the engine
start/stop button to the ON position.
3. Move the shift lever.
If the brake pedal is repeatedly
depressed and released with the shift
lever in the P (Park) position, a chattering
noise near the shift lever may be heard.
This is a normal condition.Shift-lock override
If the shift lever cannot be moved from
the P (Park) position into R (Reverse)
position with the brake pedal depressed,
continue depressing the brake, then do
the following:
1. Carefully remove the cap (1) covering
the shift-lock access hole.
2. Insert a key (or screwdriver) into the
access hole and press down on the
key (or screwdriver).
3. Move the shift lever.
4. Have your vehicle inspected by an
authorized HYUNDAI dealer immedi-
ately.
WARNING
Always fully depress the brake
pedal before and while shifting out
of the P (Park) position into anoth-
er position to avoid inadvertent
motion of the vehicle which could
injure persons in or around the car.

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 warning
light 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.

WARNING
Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible
tire failure that could lead to a
crash.
Overloading your vehicle can
cause increased stopping dis-
tances that could lead to a
crash.
A crash resulting from poor
handling, vehicle damage, tire
failure, or increased stopping
distances could result in seri-
ous injury or death.
WARNING - Loose cargo
Items you carry inside your
vehicle can strike and injure
occupants in a sudden stop or
turn, or in a crash.
Put items in the cargo area of
your vehicle. Try to spread the
weight evenly.
Never stack items, like suit-
cases, inside the vehicle
above the tops of the seats.
Do not leave an unsecured
child restraint in your vehicle.
When you carry something
inside the vehicle, secure it.
Do not drive with a seat folded
down unless necessary.CAUTION
Overloading your vehicle may
cause damage. Repairs would
not be covered by your warran-
ty. Do not overload your vehicle.
Using heavier suspension com-
ponents to get added durability
might not change your weight
ratings. Ask your dealer to help
you load your vehicle the right
way.

What to do in an emergency
If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. 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 pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.
Make certain during wheel
removal that the same nuts that
were removed are reinstalled -
or, if replaced, that nuts with
metric threads and the same
chamfer configuration are used.
Installation of a non-metric
thread nut on a metric stud or
vice-versa will not secure the
wheel to the hub properly and
will damage the stud so that it
must be replaced.
Note that most lug nuts do not
have metric threads. Be sure to
use extreme care in checking
for thread style before installing
aftermarket lug nuts or wheels.
If in doubt, consult an author-
ized HYUNDAI dealer.
WARNING- Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to the
loss of the wheel and a collision
resulting in serious injuries.
WARNING - Inadequate
spare tire pressure
Check the inflation pressures as
soon as possible after installing
the spare tire. Adjust it to the
specified pressure, if necessary.
Refer to “Tires and wheels” sec-
tion 8.

Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-
quent oil and filter changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. Fuel filters should be
installed by an authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum hoses and crankcase
ventilation hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.

WASHER FLUID
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 44 lb (20 kg, 196 N) of
force. Also, the parking brake alone should
securely hold the vehicle on a fairly steep
grade. If the stroke is more or less than
specified, have the parking brake adjusted
by an authorized HYUNDAI dealer.
Stroke : 4~5 notch
WARNING -Coolant
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.
Windshield washer fluid agents
contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi-
sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.
