• Use a towing cable or chain less than 5
m (16 feet) long. Attach a white or red
cloth (about 30 cm (12 inches) wide)
in the middle of the cable or chain for
easy visibility.
• Drive carefully so the towing cable or
chain remains tight during towing.
• Before towing, check the Automated
manual transmission for fluid leaks
under your vehicle. If the Automated
manual transmission fluid is leaking,
flatbed equipment or a towing dolly
must be used.
NOTICE
Accelerate or decelerate the vehicle
in a slow and gradual manner while
maintaining tension on the tow rope
or chain to start or drive the vehicle,
otherwise tow hooks and the vehicle
may be damaged.
NOTICE
To avoid damage to your vehicle and
vehicle components when towing:
• Always pull straight ahead when
using the towing hooks. Do not pull
from the side or at a vertical angle.
• Do not use the towing hooks to pull
a vehicle out of mud, sand or other
conditions from which the vehicle
cannot be driven out under its own
power.
• The vehicle should be towed at a
speed of 25 km/h (15 mph) or less
within the distance of 20 km (12
miles). (for Manual transmission/
Automated manual transmission
vehicle)
• The vehicle should be towed at a
speed of 15 km/h (10 mph) or less
within the distance of 1.5 km (1
mile). (for Dual clutch transmission/
Intelligent variable transmission
vehicle)

While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check the coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year
(i.e., every Spring and Fall):
• Check the radiator, heater and air
conditioning hoses for leaks or
damage.
• Check the windshield washer spray
and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
• Check the headlight alignment.
• Check the muffler, exhaust pipes,
shields and clamps.
• Check the lap/shoulder belts for wear
and function.
At least once a year:
• Clean the body and door drain holes.
• Lubricate the door hinges and checks,
and hood hinges.
• Lubricate the door and hood locks and
latches.
• Lubricate the door rubber
weatherstrips.
• Check the air conditioning system.
• Inspect and lubricate Automated
manual transmission linkage and
controls.
• Clean the battery and terminals.
• Check the brake/clutch fluid level.

Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for
evidence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration.
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 contact 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 present.
Hoses should be replaced immediately if
there is any evidence of deterioration or
damage.
Air cleaner filter
We recommend that the air cleaner filter
be replaced by an authorized HYUNDAI
dealer.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
WARNING
Do not disconnect and inspect spark
plugs when the engine is hot. You may
burn yourself.
Valve clearance (For 1.0 T-GDi)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
We recommend that the system be
serviced by an authorized HYUNDAI
dealer.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transmission fluid
(if equipped)
Inspect the manual transmission fluid
according to the maintenance schedule.
Automated manual transmission
fluid (if equipped)
Inspect the Automated manual
transmission fluid according to the
maintenance schedule.

Maintenance
NOTICE
The use of non-specified fluid
(even marked as compatible with
genuine) could result in shift quality
deterioration and vibrations,
eventually, the transmission failure.
Use only specified Automated
manual transmission fluid. (Refer
to “Recommended lubricants and
capacities” in chapter 2.)
Intelligent VariableTransmission
(IVT) Fluid (if equipped)
Intelligent Variable Transmission (IVT)
Fluid should not be checked under
normal usage conditions. But, the
Intel-ligent Variable Transmission (IVT)
Fluid should be changed under severe
usage conditions. We recommend that
the Intelligent Variable Transmission
(IVT) Fluid changed by an authorized
HYUNDAI dealer according to the
maintenance schedule. (Refer to
“Maintenance Under Severe Usage
Conditions” in this chapter.)
i Information
Intelligent variable transmission (IVT)
fluid color is basically light amber. As the
vehicle is driven, the intelligent variable
transmission (IVT) fluid will begin to
look darker. This is a normal condition
and you should not judge the need to
replace the fluid based upon the changed
color.
NOTICE
The use of non-specified fluid (even
marked as compatible with genuine)
could result in shift quality deteriora-
tion and vibrations, and eventual
transmission failure. Use only specified
Intelligent Variable Transmission
(IVT) fluid. (Refer to “Recommended
lubricants and capacities” in chapter 8.)
