ESC OFF usage
When driving
• ESC should be turned on for daily
driving whenever possible.
• To turn ESC off while driving, press
the ESC OFF button while driving
on a flat road surface.
✽NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated and the buzzer beeps)
by pressing the button for 3 sec-
onds. If the ESC is left on, it may
prevent the vehicle speed from
increasing, and result in false diag-
nosis.
• Turning the ESC off does not
affect ABS or brake system opera-
tion. CAUTION
Driving with varying tire or
wheel sizes may cause the ESC
system to malfunction. When
replacing tires, make sure they
are the same size as your origi-
nal tires.
WARNING
The Electronic Stability Control
is only a driving aid; use pre-
cautions for safe driving by
slowing down on curved,
snowy, or icy roads. Drive slow-
ly and don’t attempt to acceler-
ate whenever the ESC indicator
light is blinking, or when the
road surface is slippery.
WARNING
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.
CAUTION
Even if you cancel the ESC
function by pressing the button,
the ESC function may be operat-
ed. It is normal condition for
safety driving.

Driving your vehicle
More severe weather conditions of
winter result in greater wear and
other problems. To minimize winter
driving problem, you should follow
these suggestions:
Snowy or icy conditions
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
If snow tires are needed, it is neces-
sary to select tires equivalent in size
and type of the original equipment
tires. Failure to do so may adversely
affect the safety and handling of your
car. Furthermore, speeding, rapid
acceleration, sudden brake applica-
tions, and sharp turns are potentially
very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur. You
need to keep sufficient distance
between the vehicle in operation in
front and your vehicle. Also, apply
the brake gently. It should be noted
that installing tire chains on the tire
will provide a greater driving force,
but will not prevent side skids.
✽NOTICE
Tire chains are not legal in all coun-
tries. Check the country laws before
fitting tire chains.
Snow tires
If you mount snow tires on your vehi-
cle, make sure they are 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.
Keep in mind that the traction provid-
ed by snow tires on dry roads may
not be as high as your vehicle's orig-
inal equipment tires. You should drive
cautiously even when the roads are
clear. Check with the tire dealer for
maximum speed recommendations.
Do not install studded tires without
first checking local, state and munic-
ipal regulations for possible restric-
tions against their use.
WINTER DRIVING
WARNING- Snow tire
size
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.

245/50R18 Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by
mounting some types of snow chains
on them. Therefore, the use of snow
tires is recommended instead of
snow chains. Do not mount tire
chains on vehicles equipped with
aluminum wheels; snow chains may
cause damage to the wheels. If snow
chains must be used, use wire-type
chains with a thickness of less than
12 mm (0.47 in). Damage to your
vehicle caused by improper snow
chain use is not covered by your
vehicle manufacturers warranty.
Install tire chains only on the rear
tires.Chain installation
When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear the chains contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
chains as soon as you begin driving
on cleared roads.
CAUTION
• Make sure the snow chains
are the correct size and type
for your tires. Incorrect snow
chains can cause damage to
the vehicle body and suspen-
sion and may not be covered
by your vehicle manufacturer
warranty. Also, the snow chain
connecting hooks may be
damaged from contacting
vehicle components causing
the snow chains to come
loose from the tire. Make sure
the snow chains are SAE
class “S” certified.
• Always check chain installa-
tion for proper mounting after
driving approximately 0.5 to 1
km (0.3 to 0.6 miles) to ensure
safe mounting. Retighten or
remount the chains if they are
loose.
WARNING
- Mounting chains
When mounting snow chains,
park the vehicle on level ground
away from traffic. Turn on the
vehicle Hazard Warning flashers
and place a triangular emer-
gency warning device behind
the vehicle if available. Always
place the vehicle in P (Park),
apply the parking brake and
turn off the engine before
installing snow chains.

Chain installation
When installing the AutoSock (fabric
snow chain), follow the manufactur-
er's instructions and mount them as
tightly as you can. Drive slowly with
the AutoSock (fabric snow chain)
installed. If you hear the AutoSock
(fabric snow chain) contacting the

them. If they still make contact, slow
down until it stops. Remove the
AutoSock (fabric snow chain) as
soon as you begin driving on cleared
roads.Use high quality ethylene gly-
col 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 section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in section 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.CAUTION
• The AutoSock (fabric snow
chain) that are the wrong size
or improperly installed can
damage your vehicle's brake
lines, suspension, body and
wheels.
• Stop driving and retighten the
AutoSock (fabric snow chain)
any time you hear them hitting
the vehicle.
WARNING - Tire chains
• The use of the AutoSock (fab-
ric snow chain) may adversely
affect vehicle handling.
• Do not exceed 30 km/h (20
mph) or the AutoSock (fabric
snow chain) manufacturer’s
recommended speed limit,
whichever is lower.
• Drive carefully and avoid
bumps, holes, sharp turns, and
other road hazards, which may
cause the vehicle to bounce.
• Avoid sharp turns or locked-
wheel braking.

What to do in an emergency
TIRE PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED)
(1) Low tire pressure telltale /
TPMS malfunction indicator
(2) Low tire pressure position telltale
(Shown on the LCD display)Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label.
(If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly 1 minute and then remain continu-
ously illuminated. This sequence will
continue upon subsequent vehicle
start-ups as long as the malfunction
exists. When the TPMS malfunction
indicator remains illuminated after
blinking for approximately 1 minute,
the system may not be able to detect
or signal low tire pressure as intend-
ed.

Maintenance
TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla-
tion 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
1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire under-
inflation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.
OBH088004N
CAUTION
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
• Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread, and
a greater possibility of dam-
age from road hazards.

Maintenance
42 7
Disc brake pads should be inspected
for wear whenever tires are rotated.
✽NOTICE
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
Wheel alignment and tire bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance. In most
cases, you will not need to have your
wheels aligned again. However, if you
notice unusual tire wear or your vehi-
cle pulling one way or the other, the
alignment may need to be reset. If
you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
Tire replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1.6 mm (1/16 inch) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
WARNING
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
could result in death, severe
injury, or property damage.
CAUTION
Improper wheel weights can
damage your vehicle's aluminum
wheels. Use only approved wheel
weights.
