NOTICE
• It is permissible to add 3 psi to the standard tire pressure specification if colder
temperatures are expected soon.
Tires typically lose 1psi (7kPa) for every 12°F temperature drop. If extreme
temperature variations are expected, recheck your tire pressure as necessary to
keep them properly inflated.
• Tire inflation pressures will vary with changes in elevation. If driving in areas of
higher or lower elevation, be sure to check and adjust for proper tire inflation.
CAUTION
• When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or not work properly.
• When replacing tires, ALWAYS use the same size, type, construction and tread
pattern supplied with the vehicle for all tires.

ESC OFF usage
When Driving
The ESC OFF mode should only be used
brie
fly to help free the vehicle if stuck in
snow by temporarily stopping operation
of the 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.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management (VSM)
is a function of the Electronic Stability
Control (ESC) system. It helps ensure the
vehicle stays stable when accelerating
or braking suddenly on wet, slippery and
rough roads where traction over the four
tires can suddenly become uneven.
WARNING
Take the following precautions when
using the Vehicle Stability Management
(VSM):
• ALWAYS check the speed and the
distance to the vehicle ahead. The
VSM is not a substitute for safe
driving practices.
• Never drive too fast for the road
conditions. The VSM system will not
prevent accidents. Excessive speed
in bad weather, slippery and uneven
roads can result in severe accidents.
VSM operation
VSM ON condition
The VSM operates when:
•
The Electronic Stability Control (ESC)
is on.
• Vehicle speed is approximately above 9 mph (15 km/h) on curve roads.
• Vehicle speed is approximately above 12 mph (20 km/h) when the vehicle is
braking on rough roads.
When operating
When you apply your brakes under
conditions which ma
y activate the ESC,
you may hear sounds from the brakes,
or feel a corresponding sensation in the
brake pedal. This is normal and it means
your VSM is active.
NOTICE
The VSM does not operate when:
• Driving on a banked road such as
gradient or incline.
• Driving rearward.
• ESC OFF indicator light is on.
• EPS (Electric Power Steering)
warning light (
) is on or blinks.

SPORT mode
SPORT mode manages the
driving dynamics by
automatically adjusting the
steering effort, the engine
and transmission control
logic for enhanced driver
performance.
• When SPORT mode is selected by using the DRIVE MODE button, the
SPORT indicator will illuminate.
• Whenever the engine is restarted, the Drive Mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode from
the DRIVE MODE button.
• When SPORT mode is activated: - The engine rpm will tend to remain raised over a certain length of time
even after releasing the accelerator
- Upshifts are delayed when accelerating
Information
In SPORT mode, the fuel efficiency may
decrease.
SMART mode
6 0 $ 5 7
SMART mode selects the
proper driving mode among
NORMAL and SPORT by
judging the driver’s driving
habits (i.e. Economic or
Aggressive (Sportive)) from
the brake pedal depression
or the steering wheel
operation.
• Toggle the DRIVE MODE button to select SMART mode. When SMART
mode is selected, the indicator
illuminates on the instrument cluster.
• SMART mode automatically controls the vehicle driving, such as gear
shifting patterns and engine torque,
in accordance with the driver’s driving
habits.
Information
When you dynamically drive the vehicle
in SMART mode by abruptly decelerating
or sharply turning the driving mode
changes to SPORT mode. However, it may
adversely affect fuel economy.

Lane Keeping Assist system detect lane
markers on the road with a camera at
the front windshield, and assists the
driver’s steering to help keep the vehicle
between lanes.
When the system detects the vehicle
straying from its lane, it alerts the driver
with a visual and audible warning, while
applying a counter-steering torque,
trying to help prevent the vehicle from
moving out of its lane.
WARNING
Lane Keeping Assist system is not a
substitute for safe driving practices, but
a convenience function only. It is the
responsibility of the driver to always be
aware of the surroundings and steer the
vehicle.
WARNING
Take the following precautions when
using Lane Keeping Assist system:
• Do not turn the steering wheel
suddenly when the steering wheel is
being assisted by the system.
• LKA system helps to prevent the
driver from moving out of the lane
(or road) unintentionally by assisting
the driver’s steering. However, the
driver should not solely rely on the
system but always pay attention on
the steering wheel to stay in the lane.
• The operation of LKA system can
be cancelled or not work properly
according to road condition and
surroundings. Always be cautious
when driving.
• Do not disassemble LKA system
camera temporarily to tint the
window or attach any types of
coatings and accessories. If you
disassemble the camera and
assemble it again, have the vehicle
inspected by an authorized HYUNDAI
dealer and have the system checked
for calibration.

Emergency Situations7-16
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact spare tire at a time.
NOTICE
When the original tire and wheel are
repaired and reinstalled on the vehicle,
the lug nut torque must be set correctly.
The correct lug nut tightening torque is
79~94 lbf·ft (11~13 kgf·m).
CAUTION
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately 1
inch (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.

Maintenance8-36
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]).
Without a spare tireWithout a spare tire
ODH073802ODH073802
Disc brake pads should be inspected for
wear whenever tires are rotated.
Information
Tires that are asymmetrical or directional
can only be installed on the wheel in
one direction. The outside and inside
of an asymmetrical tire is not easily
distinguishable. Pay careful attention to
the markings on the sidewalls of the tires,
noting the “outside” marking and also the
rotating direction before installing them
on the vehicle.
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.
Wheel Alignment and Tire
Balance
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
vehicle 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.
NOTICE
Improper wheel weights can damage
your vehicle’s aluminum wheels. Use
only approved wheel weights.
