Tires and Wheels
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.
• Tire inflation pressures may vary depending on changes in elevation. If driving in areas of higher or lower elevation, be sure to check and adjust for proper tire inflation.
• Do not exceed the maximum inflation pressure, as found on the sidewall of the tire(s).

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.

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.

Information • Turning ESC off does not affect ABS or standard brake system operation.
• Select 0 step of the regenerative braking system and depress the brake pedal around
10 times to efficiently apply brake disc
cleaning.
Brake disc cleaning may decrease the
driving distance by restraining the regenerative braking system. After brake
disc cleaning, the regenerative braking
system may be restored.
If the regenerative braking system is not
restored after the brake disc cleaning, have
the vehicle inspected by an authorized
HYUNDAI dealer.

Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) system. It helps the vehicle
stay 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 Vehicle Stability Management:
• ALWAYS check the speed and the distance to the vehicle ahead. VSM is
not a substitute for safe driving
practices.
• Never drive too fast for the road conditions. VSM will not prevent
accidents. Excessive speed in bad
weather, on slippery and uneven roads
can result in severe accidents.

VSM operation
When operating
When you apply your brakes under
conditions which may activate 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.

Control System (AWD)
Drive Mode
B6009701
Drive mode may be selected according to
the driver's preference or road condition.
B6009702
The mode changes whenever the driver
pushes the DRIVE mode button.
NORMAL mode
Normal mode is a driving that provides
comfortable driving with normal motor
response. The vehicle is driven mainly
with the rear wheels (2WD), and
automatically converts to AWD according
to the road and driving conditions.
ECO mode
ECO mode is a driving mode vehicles
could change the engagement status of the motor according to the situation
required. Auto changing the driving
mode(2WD/AWD)helps improve energy
efficiency.
Electric energy efficiency varies
according to the driver's driving habit and
road condition.
• When ECO mode is selected, the ECO
indicator illuminates on the instrument
cluster and the color of the mood lamp
is changed.
• When ECO mode is activated: - The acceleration response may be slightly reduced if the accelerator
pedal is depressed moderately.
- The air conditioner performance may be limited.
- The shift pattern of the gear may change.
The above situations are normal
conditions when ECO mode is
activated to help improve electric
energy efficiency.
Limitations of ECO mode
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though there is
no change in the ECO indicator.
• When coolant temperature is low: The system will be limited until motor
performance becomes normal.
• When driving up a hill: The system will be limited to gain
power when driving uphill because
motor torque is restricted.
SPORT mode
SPORT mode is a driving mode improving
driving performance by fixing AWD
system and controlling gear.
In SPORT mode, the electric energy
efficiency may decrease.
• When SPORT mode is selected, the SPORT indicator illuminates on the
)PME

Explanation of Scheduled
Maintenance Items
Cooling System
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Gear Fluid
The gear fluid should be inspected and
replaced according 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.
Brake Discs, Pads, Calipers
and Rotors
Check the pads, the discs, and the rotors
for any excessive wear-out. Inspect
calipers for any fluid leakage.
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 vehicle
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.

Maintenance
9-22
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 wheel lug nut
tightness (proper torque is 79-94
lbf·ft (11-13kgf·m).
B9005001
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information When installing an unsymmetrical tire,
install the side marked “outside” facing
out.
