NOTICE
• It is permissible to add 20 kPa (3 psi) to the standard tire pressure specification if
colder temperatures are expected soon. Tires typically lose 7 kPa (1 psi) for every
7°C (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.

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle from
a stop on a hill. The system operates the
brakes automatically for approximately
2 seconds and releases the brake after 2
seconds or when the accelerator pedal is
depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off on
a incline. The HAC activates only for
approximately 2 seconds.
NOTICE
• The HAC does not operate when
the shift button is in P (Park) or N
(Neutral)
• The HAC activates even though the
ESC (Electronic Stability Control) is
off but does not activate when the ESC has malfunctioned.
Good Braking Practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift button into P
(Park) position, then apply the parking
brake, and place the ignition switch in
the LOCK/OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop as
quickly if the brakes are wet. Wet brakes
may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the vehicle
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorized HYUNDAI dealer for
assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.

The severe weather conditions of winter
quickly wear out tires and cause other
problems. To minimize winter driving
problems, you should take the following
suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
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 the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tow straps or chains, a flashlight,
emergency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
WARNING
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 affected.
If you mount snow tires on your vehicle,
make sure to use 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. The traction
provided by snow tires on dry roads
may not be as high as your vehicle's
original equipment tires. Check with
the tire dealer for maximum speed
recommendations.
Information
Do not install studded tires without first checking local, country and municipal
regulations for possible restrictions against
their use.

Tire Pressure Monitoring System
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
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 pressure 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 pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly 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 maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination 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 malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, have
the system checked by an authorized
HYUNDAI dealer.
1. The Low Tire Pressure TPMS Malfunction Indicator does not
illuminate for 3 seconds when the
ignition switch is placed to the ON position or engine is running.
2. The TPMS Malfunction Indicator remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure LCD display remains illuminated

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 420
kPa (60 psi).
• 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
11~13 kgf·m (79~94 lbf·ft).
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 25
mm (1 inch).
• 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.
