Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your
brakes and hold the brake pedal down
while you:
• Start your engine;
• Shift into gear; and
• Release the parking brake.
2.
Slowly r

emove your foot from the
brake pedal.
3.
Drive slo

wly until the trailer is clear of
the chocks.
4.
St

op and have someone pick up and

Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.
• Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.

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 indicator 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, we
recommend that you have the system
checked by an authorized HYUNDAI
dealer.
1.
The Lo
w Tire Pressure Telltale/TPMS
Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or the vehicle is in
the ready (
) mode.
2.
The TPMS Malfunction Indica
tor
remains illuminated after blinking for
approximately 1 minute.
3.
The Lo

w Tire Pressure Position
Telltale remains illuminated.

WARNING
Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience or
the proper tools and equipment to do
the work, we recommend that having it
done by an authorized HYUNDAI dealer.
ALWAYS follow these precautions for
performing maintenance work:
• Park your vehicle on level ground,
move the shift button into the P
(Park) position, apply the parking
brake, and place the ignition switch
in the LOCK/OFF position.
• Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.
• If you must run the engine during
maintenance, do so out doors or in
an area with plenty of ventilation.
• Keep flames, sparks, or smoking
materials away from the battery and
fuel-related parts. The following lists are vehicle checks and
inspections that should be performed
by the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
