What to do in an emergency
6
Use a towing cable or chain less
than 5 m long. Attach a white or red
cloth (about 30 cm 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 automatic
transmission/dual clutch transmis-
sion for fluid leaks under your vehi-
cle. If the automatic transmission
fluid is leaking, flatbed equipment
or a towing dolly must be used.Accelerate or decelerate the vehi-
cle 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.
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.
Limit the vehicle speed to
15 km/h and drive less than 1.5
km when towing to avoid seri-
ous damage to the automatic
transmission/dual clutch trans-
mission.

You should exercise the utmost care
to prevent damage to your vehicle
and injury to yourself whenever per-
forming any maintenance or inspec-
tion procedures.
We recommend you have your vehi-
cle maintained and repaired by an
authorised HYUNDAI dealer. An
authorised HYUNDAI dealer meets
HYUNDAI’s high service quality stan-
dards and receives technical support
from HYUNDAI in order to provide
you with a high level of service satis-
faction.
Owner’s responsibility
Maintenance service and record reten-
tion are the owner’s responsibility.
You should retain documents that show
proper maintenance has been per-
formed on your vehicle in accordance
with the scheduled maintenance serv-
ice charts shown on the following
pages. You need this information to
establish your compliance with the
servicing and maintenance require-
ments of your vehicle warranties.Detailed warranty information is pro-
vided in your Service Passport.
Repairs and adjustments required as
a result of improper maintenance or
a lack of required maintenance are
not covered.
Owner maintenance precautions
Inadequate, incomplete or insufficient
servicing may result in operational
problems with your vehicle that could
lead to vehicle damage, an accident,
or personal injury. This chapter pro-
vides instructions only for the mainte-
nance items that are easy to perform.
Several procedures can be done only
by an authorised HYUNDAI dealer
with special tools.
Your vehicle should not be modified in
any way. Such modifications may
adversely affect the performance,
safety or durability of your vehicle and
may, in addition, violate conditions of
the limited warranties covering the
vehicle.Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details, read
the separate Service Passport pro-
vided with the vehicle. If you're
unsure about any servicing or main-
tenance procedure, we recommend
that the system be serviced by an
authorised HYUNDAI dealer.

The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an authorised
HYUNDAI dealer at the frequencies
indicated to help ensure safe, depend-
able operation of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer
as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labour, parts and lubricants used. Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, we recommend that the
system be serviced by an autho-
rised HYUNDAI dealer. ALWAYS
follow these precautions for
performing maintenance work:
Park your vehicle on level
ground, move the shift lever
into the P (Park, for automatic
transmission/dual clutch trans-
mission vehicle) position, apply
the parking brake, and place
the ignition switch in the
LOCK/OFF position.
(Continued)
WARNING (Continued)
Block the tyres (front and
back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
ellery that can become entan-
gled in moving parts.
If you must run the engine
during maintenance, do so
out doors or in an area with
plenty of ventilation.
Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst 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 if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when
travelling 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 transmissiom
occurs, check the transmissiom fluid
level.
Check the automatic transmission/
dual clutch transmission P (Park)
function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal). Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm, whilst running the
diesel engine. The high currents
of the electronic engine control
system produce a considerable
amount of magnetic fields.
WARNING

7-8
Maintenance
At least monthly:
Check 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
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
Check for loose wheel nuts.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
Check headlamp alignment.
Check muffler, exhaust pipes,
shields and clamps.
Check the seat belts for wear and
function.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and bonnet
hinges.
Lubricate door and bonnet locks
and latches.
Lubricate door rubber weather
strips.
Check the air conditioning system.
Inspect and lubricate automatic
transmission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.
