Electric Power Steering (EPS)
The system assists you with steering the
vehicle. If the vehicle is turned off or
if the power steering system becomes
inoperative, you may still steer the
vehicle, but it will require increased
steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend that
you have the system checked by an
authorized HYUNDAI dealer.
CAUTION
If Electric Power Steering does not
operate normally, the warning light and the message ‘Check motor driven
power steering’ will illuminate on the
instrument cluster. You may steer the
vehicle, but it will require increased
steering efforts. We recommend that
you take your vehicle to an authorized
HYUNDAI dealer or to a service station
and have the system checked as soon as
possible.
Information
The following symptoms may occur during
normal vehicle operation:
• The steering effort may be high
immediately after pressing the Engine
Start/Stop button to the ON position.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics are completed, the steering
wheel effort will return to its normal
condition.
• When the battery voltage is low, you
might have to put more steering effort.
However, it is a temporary condition so
that it will return to normal condition
after charging the battery.
• A click noise may be heard from the
EPS relay after the Engine Start/Stop
button is in the ON or OFF position.
• Motor noise may be heard when the
vehicle is at a stop or at a low driving
speed.
• When you operate the steering wheel
in low temperatures, abnormal noise
may occur. If the temperature rises, the
noise will disappear. This is a normal
condition.
• When an error is detected from EPS,
the steering effort assist function will
not be activated in order to prevent
fatal accidents. Instrument cluster
warning lights may be on or the
steering effort may be high. If these
symptoms occur, drive the vehicle
to a safe area as soon as it is safe to
do so. We recommend that you have
the system checked by an authorized
HYUNDAI dealer as soon as possible.

days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• Use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
• If you operate the air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection knob to
the
position and set the fan speed control knob to the lowest speed
setting.

we recommend the system be checked
at an authorized HYUNDAI dealer.
Air Conditioning Performance and
Maintenance at Your HYUNDAI
Dealer
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning system.
Therefore, if abnormal operation is found, we
recommend that the system be inspected by
an authorized HYUNDAI dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable and
operated at high pressure,
the air conditioning system
should only be serviced
by trained and certified
technicians. It is important
that the correct type and
amount of oil and refrigerant
are used.
All refrigerants should be reclaimed
with proper equipment.

Chain Installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:
• Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 0.47 in.
(12mm) thick to prevent damage to
the chain’s connection.
Winter precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not
sure about a type of winter weight oil,
we recommend that you consult an
authorized HYUNDAI dealer.

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 remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and
store the chocks.
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.
