Immobiliser system
The immobiliser system protects your
vehicle from theft. If an improperly
coded key (or other device) is used, the
H Q J L Q HT V I X H O V \ V W H P L V G L V D E O H G
When the ignition switch is placed in
the ON position, the immobiliser system
indicator should come on briefly, then
go off. If the indicator starts to blink, the
system does not recognise the coding of
the key.
Place the ignition switch to the LOCK/
OFF position, then place the ignition
switch to the ON position again.
The system may not recognise your
N H \T V F R G L Q J L I D Q R W K H U L P P R E L O L V H U N H \
or other metal object (i.e., key chain) is
near the key. The engine may not start
because the metal may interrupt the
transponder signal from transmitting
normally.
If the system repeatedly does not
recognise the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobiliser password is a customer
unique password and should be kept
confidential.
NOTICE
The transponder in your key is an
important part of the immobiliser
system. It is designed to give years
of trouble-free service, however you
should avoid exposure to moisture,
static electricity and rough handling.
Immobiliser system malfunction could
occur.

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.
