Driving your vehicle
Use wire chains less than 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 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 chapter 7. 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 7.The battery charging level
can be checked by an authorised
HYUNDAI dealer or in a service sta-
tion.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 chapter
8. When you are not sure about a
type of winter weight oil, consult an
authorised HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in 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.

What to do in an emergency
If you have a flat tyre whilst
driving
If a tyre goes flat whilst you are driv-
ing:
Take your foot off the accelerator
pedal and let the vehicle slow
down whilst driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes. When the vehicle is stopped, press
the hazard warning flasher button,
move the shift lever into P (Park,
for automatic transmission/dual
clutch transmission vehicle) or neu-
tral (for manual transmission vehi-
cle), apply the parking brake, and
place the ignition switch in the
LOCK/OFF position.
Have all passengers get out of the
vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tyre, follow
the instructions provided later in
this chapter.If the engine doesn't turn over
or turns over slowly
Be sure the shift lever is in N
(Neutral) or P (Park) if it is an auto-
matic transmission/dual clutch
transmission vehicle. The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
Check the battery connections to
be sure they are clean and tight.
Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to start
it. This could cause damage to your
vehicle.See instructions for "Jump
Starting" provided in this chapter.
