SRS Care
The SRS is virtually maintenance-free
and there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate
when the ignition switch is in the ON
position, or continuously remains on,
we recommend that the system be
immediately inspected by a HYUNDAI
authorised repairer.
We recommend any work on the SRS
system, such as removing, installing,
repairing, or any work on the steering
wheel, the front passenger’s panel, front
seats and roof rails be performed by a
HYUNDAI authorised repairer. Improper
handling of the SRS system may result in
serious personal injury.
WARNING
To reduce the risk of serious injury or
death take the following precautions:

[Do not attempt to modify or
disconnect the SRS components or
wiring, including the addition of any
kind of badges to the pad covers or
modifications to the body structure.

[Do not place objects over or near
the air bag modules on the steering
wheel, instrument panel, and the
front passenger’s panel above the
glove box.

[Clean the air bag pad covers with
a soft cloth moistened with plain
water. Solvents or cleaners could
adversely affect the air bag covers
and proper deployment of the
system.

[We recommend that inflated air bags
be replaced by a HYUNDAI authorised
repairer.

[If components of the air bag system
must be discarded, or if the vehicle
must be scrapped, certain safety
precautions must be observed.
We recommend that you consult a
HYUNDAI authorised repairer for
the necessary information. Failure
to follow these precautions could
increase the risk of personal injury.

This gauge indicates the current outside
air temperatures either in Celsius (°C) or
Fahrenheit.
- Temperature range :
-40°C ~ 60°C (-40°F ~ 140°F)
Note that the temperature indicated
on the LCD display may not change
as quickly as the outside temperature(
there may be a slight delay before the
temperature changes.)
You can change the temperature unit
from the Settings menu in the Cluster.
Select:
- Setup J Unit J Temperature Unit
J °C/°F
For vehicles equipped with Automatic
Climate Control, you can also:
- Press the AUTO button whilst pressing
the OFF button on the climate control
unit for 3 seconds
Both the temperature unit on the cluster
LCD display and climate control screen
will change.
Odometer
„3.5-Inch
OPDE046141R/OBC3040030R
„10.25-Inch
The odometer indicates the total
distance that the vehicle has been
driven and should be used to determine
when periodic maintenance should be
performed.
Distance to empty
„3.5-Inch
OOS048469N/OBC3040031R

Climate control air filter
OIK047401L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the
heating and air conditioning system.
We recommend that the climate control
air filter be replaced by a HYUNDAI
authorised repairer according to the
maintenance schedule. If the vehicle is
being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at a HYUNDAI authorised repairer.

Climate control air filter
OIK047401L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system. If
dust or other pollutants accumulate in
the filter over a period of time, the air
flow from the air vents may decrease,
resulting in moisture accumulation
on the inside of the windscreen even
when the outside (fresh) air position is
selected.
If this happens, we recommend that the
climate control air filter be replaced by a
HYUNDAI authorised repairer.

When installing tyre 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 tyre 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 tyre 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 tyre chains on vehicles
equipped with aluminium wheels. If
unavoidable, use a wire type chain.

[Use wire chains less than 0.47 in (12
mm) wide 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. 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 the chapter
9. The battery charging level can be
checked by a HYUNDAI authorised
repairer 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. For
further information, refer to the chapter
2. When you are not sure about a type
of winter weight oil, consult a HYUNDAI
authorised repairer.

Driving your vehicle
Ready to leave after parking on a
hill
1. With the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle), apply
your brakes and hold the brake pedal
down whilst you:

V Start your engine;

V Shift into gear; and

V 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,
automatic transmission/dual clutch
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 towbar.
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 towbar nuts and
bolts should be tight.
NOTICE
To prevent vehicle damage:

V 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.

V When towing check Automatic
transmission/Dual clutch
transmission fluid more frequently.

V If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
