maintenance HYUNDAI I20 2017 User Guide

When using tire chains:
• Wrong size chains or improperlyinstalled chains can damage your
vehicle's brake lines\b suspension\b
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains contacting the body\b retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage\b retighten the chains after driving \f.5~1.\f km
(\f.3~\f.6 miles).
• Do not use tire chains on vehic
les
equipped with aluminum wheels. If
unavoidable\b use a wire type
chain.
• Use wire chains less than 15 mm (\f.59 in) wide to prevent damage
to the chain’s connection.
Winter precautions
Use high quality ethylene glycolcoolant
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\b 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\b
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
Change to "winter weight" oil if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use\b we recommend that you
consult with an authorized HYUNDAI
dealer.
Check spark plugs and ignition system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked\b worn or
damaged in any way.

changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.Drive beltsInspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.When you are inspecting the belt,
place the ignition switch in the
LOCK/OFF or ACC position.
Fuel filterA clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by an authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nectionsCheck the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorized HYUNDAI
dealer.
NOTICE
Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectors
and high pressure pipes are sub-
ject to high pressure even a fter
the engine stopped. The fuel jet
produced by fuel leaks may cause
serious injury, if it touch the b ody.
People using pacemakers should
not move than 30cm closer to the
ECU or wiring harness within the
eng ine room while engine is run-
ning, since the high currents in the
Common Rail system produce
considerab le magnetic fields.

should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
