• Use a towing cable or chain less than
16 feet (5 m) long. Attach a white or
red cloth (about 12 inches (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 for fluid leaks under your
vehicle. If the automatic 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.
• Limit the vehicle speed to 10 mph
(15 km/h) and drive less than 1
mile (1.5 km) when towing to avoid
serious damage to the automatic
transmission.

Maintenance
8-4
You should exercise the utmost care
to prevent damage to your vehicle and
injury to yourself whenever performing
any maintenance or inspection
procedures.
We recommend you have your
vehicle maintained and repaired by
an authorized HYUNDAI dealer. An
authorized HYUNDAI dealer meets
HYUNDAI’s high service quality
standards and receives technical support
from HYUNDAI in order to provide you
with a high level of service satisfaction.
Owner’s Responsibility
Maintenance service and record
retention are the owner’s responsibility.
You should retain documents that show
proper maintenance has been performed
on your vehicle in accordance with
the scheduled maintenance service
charts shown on the following pages.
You need this information to establish
your compliance with the servicing
and maintenance requirements of your
vehicle warranties.
Detailed warranty information is
provided in your Owner’s Handbook &
Warranty Information booklet.
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 provides
instructions only for the maintenance
items that are easy to perform. Several
procedures can be done only by an
authorized 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.
Certain modifications may also be in
violation of regulations established by
the U.S. Department of Transportation
and other federal or state agencies.
NOTICE
Improper owner maintenance during
the warranty period may affect
warranty coverage. For details, read
the separate Owner’s Handbook &
Warranty Information booklet provided
with the vehicle. If you’re unsure about
any service or maintenance procedure,
have it done by an authorized HYUNDAI
dealer.

WARNING
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, have it done by an authorized
HYUNDAI dealer.
ALWAYS follow these precautions for
performing maintenance work:
• Park your vehicle on level ground,
shift the gear to P (Park), apply
the parking brake, and press the
Engine Start/Stop button to the OFF
position.
• Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled 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 smoking
materials away from the battery and
fuel-related parts. The following lists are vehicle checks and
inspections that should be performed
by the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable 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
labor, parts and lubricants used.
Owner Maintenance Schedule
When you stop for fuel:
•
Check the engine oil level.
• Check the coolant level in the engine
coolant reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated tires.
WARNING
Be careful when checking your engine
coolant/inverter 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.
