NOTICE
• It is permissible to add 3 psi (20 kPa) to the standard tire pressure specification if
colder temperatures are expected soon. Tires typically lose 1 psi (7 kPa) for every
12°F(7°C) temperature drop. If extreme temperature variations are expected,
recheck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high-altitude area above
sea level. Thus, if you plan to drive a high-altitude area, check the tire pressures
in advance. If necessary, inflate them to a proper level (Air inflation per altitude:
+2.4 psi/1 mile (+10 kPa/1 km)).
• Must do not exceed maximum inflation pressure shown on equipped tire
sidewall.
CAUTION
When replacing tires, ALWAYS use the same size, type, brand, construction and
tread pattern supplied with the vehicle. If not, it can damage the related parts or
make it work irregularly.

Indicator lights
■ ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)
If the ignition switch is placed in the
LOCK/OFF position when ESC is off, ESC
remains off. Upon restarting the vehicle,
ESC will automatically turn on again.
The ESC indicator light blinks whenever
the ESC is operating.
If the ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning light
illuminates we recommend that the
vehicle be checked by an authorized
HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on
when ESC is turned off.
WARNING
When ESC is blinking, this indicates ESC
is active:
Drive slowly and NEVER attempt to
accelerate. NEVER turn ESC off while
ESC indicator light is blinking or you
may lose control of the vehicle resulting
in an accident.
NOTICE
Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before replacing
tires, make sure all four tires and wheels
are the same size. Never drive the
vehicle with different sized wheels and
tires installed.
ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow or mud, by temporarily stopping
operation of ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the transmission:
• Do not allow wheel(s) of one axle to
spin excessively while the ESC, ABS,
and parking brake warning lights
are displayed. The repairs would not
be covered by the vehicle warranty.
Reduce engine power and do not
spin the wheel(s) excessively while
these lights are displayed.
• When operating the vehicle on
a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect ABS
or standard brake system operation.

SPORT mode
SPORT mode provides sporty
but firm riding.
In SPORT mode, the fuel
efficiency may decrease.
• When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster.
• Whenever the engine is restarted,
the drive mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode.
• When SPORT mode is activated:
- The engine rpm will tend t

o remain
raised over a certain length of time
even after releasing the accelerator
- Upshifts are dela

yed when
accelerating
SMART mode
SMART mode selects the proper
driving mode among ECO,
NORMAL and SPORT by judging
the driver's driving habits (i.e.
mild or dynamic) from the
brake pedal depression or the
steering wheel operation.
• Press the DRIVE MODE button to
activate SMART mode. When SMART
mode is activated, the indicator
illuminates on the instrument cluster.
• The vehicle starts in SMART mode,
when the engine was turned OFF in
SMART mode.
• SMART mode automatically controls
gear shifting patterns, engine torque,
in accordance with the driver's driving
habits.
Information
• When your vehicle drive mode
is selected to SMART mode, the
driving mode varies according to
your acceleration pedal input. When
your vehicle is in SMART mode and
your driving style is such that your
acceleration pedal input is gradual,
the drive mode will maximize fuel
efficiency. Note, however, the actual
fuel efficiency may vary according
to certain driving conditions (uphill/
downhill grade) and vehicle speed.
• When your vehicle is in SMART
mode and your driving style is more
aggressive such that your acceleration
pedal input is more abrupt, the drive
mode will change to reflect a more
SPORT driving characteristic. Note
that while you are driving this way, fuel
economy may be adversely affected.

Maintenance
9-14
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to DOT
4 specification.
Parking brake
Inspect the parking brake system.
Brake discs, pads, calipers and
rotors
Check the pads, the disc, and the rotor
for any excessive wear-out. Inspect
calipers for any fluid leakage
For more information on checking the
pads or lining wear limit, refer to the
HYUNDAI web site.
(http://service.hyundai-motor.com)
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks,
deterioration, or damage. Start
the engine and listen carefully for
any exhaust gas leakage. Tighten
connections or replace parts as
necessary.
Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and the hybrid
system off, check for excessive free-play
in the steering wheel. Check the linkage
for bends or damage. Check the dust
boots and ball joints for deterioration,
cracks, or damage.
Replace any damaged parts.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.
Drive Shaft and Related
Check the drive shaft, boots, clamps,
rubber couplings and center-bearing
rubber for cracks, deterioration, or
damage. Replace any damaged parts
and if necessary, repack the grease.

Tire rotation
To equalize tread wear, HYUNDAI
recommends that the tires
be rotated according to the
maintenance schedule or sooner if
irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tire pressure, improper wheel
alignment, out-of-balance wheels,
severe braking or severe cornering.
Look for bumps or bulges in the
tread or side of the tire. Replace
the tire if you find any of these
conditions. Replace the tire if fabric
or cord is visible. After rotation, be
sure to bring the front and rear tire
pressures to specification and check
lug nut tightness (proper torque is
79~94 lbf·ft [11~13 kgf·m]).
OHI078078
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The outside and inside of the
unsymmetrical tire is distinguishable.
When installing an unsymmetrical
tire, be sure to install the side marked
“outside” face the outside. If the side
marked “inside” is installed on the
outside, it will have a negative effect
on vehicle performance.
WARNING
• Do not use the compact spare
tire for tire rotation.
• Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause
loss of vehicle control resulting in
an accident.
