When towing your vehicle in an
emergency without wheel dollies :
1. Place the ignition switch in theACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.Emergency Towing
(if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service. If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Failure to place the transmis-
sion shift lever in N (Neutral)
may cause internal damage to
the transmission.

What to do in an emergency

Always follow these emergency tow-
ing precautions:
• Place the ignition switch in theACC position so the steering wheel
is not locked.
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force. 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 tow-
ing.
Before towing, check the automat- ic transmission for fluid leaks under
your vehicle. If the automatic trans-
mission fluid is leaking, flatbed
equipment or a towing dolly must
be used.
ODH063025
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 tow-
ing to avoid serious damage
to the automatic transmis-
sion.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe 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 posi-
tion.
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 automatic transmission /ecoshift 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).
At least monthly:
Check coolant level in the enginecoolant 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.
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.
