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.

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.
LANE KEEPING ASSIST (LKA)

Emergency situations
7-18
WARNING
To prevent compact spare tire failure
and loss of control possibly resulting in
an accident:
• Use the compact spare tire only in an
emergency.
• NEVER operate your vehicle over
50 mph (80 km/h).
• Do not exceed the vehicle’s
maximum load rating or the load
carrying capacity shown on the
sidewall of the compact spare tire.
• Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.
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.
• Do not tow a trailer while the compact
spare tire is installed.
Information
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).
NOTICE
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.

Maintenance
8-14
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker. This is a normal condition and you
should not judge the need to replace the
fluid based upon the changed color.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction
and failure. Use only the specified
automatic transmission fluid (refer
to “Recommended Lubricants and
Capacities” in chapter 2).
Engine Clutch Actuator Fluid
The engine clutch actuator fluid level
should be inspected or replaced to the
intervals specified in the maintenance
schedule.
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
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.
Drive Shafts and Boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if
necessary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Check Tire Inflation Pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly
inflated when they are under-
inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge
firmly onto the valve to get a
pressure measurement. If the cold
tire inflation pressure matches the
recommended pressure on the tire
and loading information label, no
further adjustment is necessary. If
the pressure is low, add air until you
reach the recommended pressure.
Make sure to put the valve caps
back on the valve stems. Without
the valve cap, dirt or moisture could
get into the valve core and cause
air leakage. If a valve cap is missing,
install a new one as soon as possible.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
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].
