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 your vehicle
6-86
NOTICE
To prevent engine and/or 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 “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.
• If you tow a trailer with the maximum
gross vehicle weight and maximum
trailer weight, it can cause the
engine or transmission to overheat.
When driving in such conditions,
allow the engine to idle until it cools
down. You may proceed once the
engine or transmission has cooled
sufficiently.
• When towing a trailer, your vehicle
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 vehicle speed according to the
maximum posted speed limit for
vehicles with trailers, the steepness
of the grade, and your trailer weight.
Parking on hills
Generally, if you have a trailer attached
to your vehicle, you should not park your
vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1.
Pull the

vehicle into the parking space.
Turn the steering wheel in the
direction of the curb (right if headed
down hill, left if headed up hill).
2.
Shift the gear to P (P

ark).
3.
Set the parking br

ake and shut off the
vehicle.
4.
Place wheel chocks under the tr

ailer
wheels on the down hill side of the
wheels.
5.
Start the v

ehicle, hold the brakes, shift
to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6.
Reapply the br

akes and parking
brakes.
7.
Shift the gear to P (P

ark) when the
vehicle is parked on a uphill grade and
in R (Reverse) on a downhill.
8.
Shut off the v

ehicle and release the
vehicle brakes but leave the parking
brake set.
WARNING
To prevent serious or fatal injury:
• Do not get out of the vehicle without
the parking brake firmly set. If you
have left the engine running, the
vehicle can move suddenly. You and
others could be seriously or fatally
injured.
• Do not apply the accelerator pedal to
hold the vehicle on an uphill.

08
8 -7
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1.
Pull off the r
oad and stop as soon as it
is safe to do so.
2.
Shift the gear to P (P

ark) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3.
If engine coolant is running out under
the v

ehicle or steam is coming 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.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury. 4.
Check for coolan

t leaking from the
radiator, hoses or under the vehicle. (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, s
top
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.
WARNING
Never remove the engine
coolant cap and/or water-
cooled intercooler coolant
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 removing the coolant 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
counterclockwise to remove it.
IF THE ENGINE OVERHEATS

Emergency situations
8-8
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost,
carefully add coolant to the reservoir
to bring the fluid level in the reservoir
up to the halfway mark.
7.
Proceed with caution, k

eeping alert
for further signs of overheating.
If overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance. CAUTION
• Serious loss of coolant indicates a
leak in the cooling system and we
recommend the system be checked
by an authorized HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities. It may require several
refilling cycles to properly fill the
engine cooling system. If necessary,
an authorized HYUNDAI dealer
should be consulted to perform this
task.

Turn the vehicle off and wait until the
engine cools down. Use extreme care
when removing the engine coolant
cap and/or water-cooled intercooler
coolant 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 counterclockwise to
remove it.
Information
The coolant level is influenced by the
engine temperature. Before checking or
refilling the coolant, turn the engine off.
WARNING
The electric motor for the cooling fan
may continue to operate or start up
when the engine is not running and
can cause serious injury. Keep hands,
clothing and tools away from the
rotating fan blades of the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.

Maintenance
9-20
Recommended coolant
• When adding coolant, use only
deionized water, distilled water or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.
• An incorrect coolant mixture can
result in severe malfunction or engine
damage.
• The engine in your vehicle has
aluminum engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.
• Do not use alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixing percentage, refer to the
following table:
Ambient
Temperature Mixture Percentage
(volume)
Antifreeze Water
5°F (-15°C) 35 65
-13°F (-25°C) 40 60
-31°F (-35°C) 50 50
-49°F (-45°C) 60 40
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of -31°F
(-35°C) and higher.
Changing coolant
We recommend that coolant be changed
by an authorized HYUNDAI dealer
according to the Maintenance Schedule
at the beginning of this chapter.
WARNING
Do not use engine coolant or antifreeze
in the washer fluid reservoir.
Engine coolant can severely obscure
visibility when sprayed on the
windshield and may cause loss of
vehicle control resulting in an accident.
Engine coolant may also cause damage
to paint and body trim.
NOTICE
To prevent damage to engine parts, put
a thick towel around the engine coolant
cap and/or inverter coolant cap before
refilling the coolant to prevent the
coolant from overflowing into engine
parts, such as the alternator.

The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations. There
are three emission control systems, as
follows.
(1)
Crank
case emission control system
(2)
Ev

aporative emission control system
(3)
Exhaust emission con

trol system
In order to ensure the proper function
of the emission control systems, it
is recommended that you have your
vehicle inspected and maintained
by an authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
NOTICE
For the Inspection and Maintenance
Test (with Electronic Stability Control
(ESC) system)
• To prevent the vehicle from misfiring
during dynamometer testing, turn
the Electronic Stability Control
(ESC) system off by pressing the ESC
switch (ESC OFF light illuminated).
• After dynamometer testing is
completed, turn the ESC system back
on by pressing the ESC switch again.
1. Crankcase emission control
sy
stem
The positive crankcase ventilation system
is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
2. Evaporative emission control
system
The Evaporative Emission Control System
is designed to prevent fuel vapors from
escaping into the atmosphere.
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve
is controlled by the Engine Control
Module (ECM); when the engine coolant
temperature is low during idling, the
PCSV closes so that evaporated fuel
is not taken into the engine. After the
engine warms-up during ordinary
driving, the PCSV opens to introduce
evaporated fuel to the engine.
