Speedometer
The speedometer indicates the
speed of the vehicle and is calibrated
in kilometers per hour (km/h) and/or
miles per hour (MPH).
Tachometer
The tachometer indicates the
approximate number of engine revo-
lutions per minute (rpm).
Use the tachometer to select the cor-
rect shift points and to prevent lug-
ging and/or over-revving the engine.
Do not operate the engine within
the tachometer's RED ZONE. This
may cause severe engine damage.
Engine Coolant Temperature
gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch is in the ON position.
If the gauge pointer moves beyond
the normal range area toward the
"130 or H (Hot)" position, it indi-
cates overheating that may dam-
age the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to "If the Engine
Overheats" in chapter 6.

Exhaust System (DPF)
Warning Light (for
diesel engine)
This warning light illuminates:
• When there is a malfunction with
Diesel Particulate Filter (DPF) sys-
tem.
• When this warning light illumi-
nates, it may turn off after driving
the vehicle:
- at more than 60 km/h (37 mph), or
- at more than 2nd gear with 1500
~ 2000 engine rpm for a certain
time (for about 25 minutes).
If this warning light blinks in spite of
the procedure (at this time LCD
warning message will be displayed),
we recommend that you have the
DPF system checked by an author-
ized HYUNDAI dealer.
If you continue to drive with the
DPF warning light blinking for a
long time, the DPF system can be
damaged and fuel consumption
can worsen.
Glow Indicator Light
(for diesel engine)
This indicator light illuminates:
• When the engine is being preheat-
ed with the ignition switch or
Engine Start/Stop Button in the ON
position.
- The engine can be started after
the glow indicator light goes off.
- The illumination time varies with
the engine coolant temperature,
air temperature, and battery con-
dition.
If the indicator light remains on or
blinks after the engine has warmed
up or while driving, there may a mal-
function with the engine preheating
system.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
Information
If the engine does not start within 10
seconds after the preheating is com-
pleted, set the ignition switch or
Engine Start/Stop Button to the
LOCK or OFF position for 10 seconds
and then to the ON position in order
to preheat the engine again.

When the ECO mode is activated:
• The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
• The air conditioner performance
may be limited.
• The shift pattern of the automatic
transmission may change.
• The engine noise may get louder.
The above situations are normal
conditions when the ECO mode is
activated to improve fuel efficiency.Limitation of the ECO mode oper-
ation:
If the following conditions occur while
the ECO mode is operating, the sys-
tem operation is limited even though
there is no change in the ECO indi-
cator.
• When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
engine torque is restricted.

Chain Installation
When installing tire chains, follow the
manufacturer's instructions and
mount them as tightly possible. Drive
slowly (less than 30 km/h (20 mph))
with chains installed. If you hear the
chains contacting the body or chas-
sis, 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.When using tire chains:
• Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, 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
0.5~1.0 km (0.3~0.6 miles).
• Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
• Use wire chains less than 15 mm
(0.59 in) 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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
NOTICE

Driving your vehicle
Check battery and cables
The winter temperature increases
the battery consumption.Inspect
the battery and cables, as speci-
fied in the chapter 7.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. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer.Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in the chapter 7.If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury.Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Do
not use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.

Driving your vehicle
To prevent engine and/or transmis-
sion (transmission) overheating:
• When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards “130 or H(Hot)” ,
pull over and stop as soon as it
is safe to do so, and allow the
engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.
• When towing a trailer, your vehi-
cle speed may be much slower
than the general flow of traffic,
especially when climbing an
uphill grade. Use the right hand
lane when towing a trailer on an
uphill grade. Choose your vehi-
cle speed according to the max-
imum posted speed limit for
vehicles with trailers, the steep-
ness of the grade, and your trail-
er weight.
(Continued)(Continued)
• For vehicles equipped with the
dual clutch transmission, some
extra precaution should be
taken when towing a trailer. Due
to the added load on the trans-
mission when towing a trailer,
the clutches may get hot if the
vehicle experiences excessive
upshifting and downshifting.
Under certain conditions, such
as repeated stop-and-go launch-
es on steep grades, the trans-
mission clutches may become
overheated. When the clutches
start to become overheated, the
transmission safe protection
mode logic is enabled. If the safe
protection mode logic is
enabled, the gear position indi-
cator on the cluster LCD display
blinks, a chime sounds, and a
warning message will appear.
(Continued)(Continued)
If the dual clutch transmission
starts to become overheated,
the gear shift characteristics
may change. Gear shifts may
become more abrupt. If contin-
ued operation while towing a
trailer includes frequent and
continuous upshifts and down-
shifts, the overheat warning
message on the cluster LCD dis-
play may illuminate. If this
occurs, stop the vehicle, apply
the brakes or shift the vehicle to
(P) Park, and allow the transmis-
sion to cool.
NOTICE

What to do in an emergency
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park, for
automatic transmission vehicle) or
neutral (for manual transmission
vehicle) and set the parking brake.
If the air conditioning is ON, turn it
OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had been
in use, it is normal for cold water to
be draining from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and we rec-
ommend that you call an authorized
HYUNDAI dealer for assistance.
IF THE ENGINE OVERHEATS
While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug while the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.
