What to do in an emergency
13. Use the wheel lug nut wrench to
tighten the lug nuts in the order
shown. Double-check each lug
nut until they are tight. After
changing tires, have an author-
ized HYUNDAI dealer tighten the
lug nuts to their proper torque as
soon as possible.The wheel lug
nut should be tightened to
79~94 lbf·ft (11~13 kgf·m).If you have a tire gauge, check the
tire pressure (see “Tires and Wheels”
in chapter 8 for tire pressure instruc-
tions.). If the pressure is lower or
higher than recommended, drive
slowly to the nearest service station
and adjust it to the recommended
pressure. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced,
air may leak from the tire. If you lose
a valve cap, buy another and install it
as soon as possible. After changing
tires, secure the flat tire and return
the jack and tools to their proper stor-
age locations.
Check the tire pressure as soon
as possible after installing a
spare tire. Adjust it to the rec-
ommended pressure.
For safety, check and re-tighten
the wheel lug nuts after driving
about 30 miles (50 km). Recheck
to make sure the lug nuts are
secure after about 600 miles
(1,000 km).If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.
NOTICE
OTL065007
■Rear
Your vehicle has metric threads
on the studs and lug nuts. Make
certain during tire changing
that the same nuts that were
removed are reinstalled. If you
have to replace your lug nuts
make sure they have metric
threads to avoid damaging the
studs and ensure the wheel is
properly secured to the hub.
Consult an authorized
HYUNDAI dealer for assistance.

Towing Service
If emergency towing is necessary,
we recommend having it done by an
authorized HYUNDAI dealer or a
commercial tow-truck service.
Proper lifting and towing procedures
are necessary to prevent damage to
the vehicle. The use of wheel dollies
or flatbed is recommended.On 2WD vehicle, it is acceptable to
tow the vehicle with the rear wheels
on the ground (without dollies) and
the front wheels off the ground. If any
of the loaded wheels or suspension
components are damaged or the
vehicle is being towed with the front
wheels on the ground, use a towing
dolly under the front wheels.
When being towed by a commercial
tow truck and wheel dollies are not
used, the front of the vehicle should
always be lifted, not the rear.
If your vehicle is an AWD vehicle, it
must be towed with a wheel lift and
dollies or flatbed equipment with all
the wheels off the ground.
An AWD vehicle should never be
towed with the wheels on the
ground. This can cause serious
damage to the transaxle or the
AWD system. Do not tow the vehicle with the
front wheels on the ground as
this may cause damage to the
vehicle.
Do not tow with sling-type
equipment. Use a wheel lift or
flatbed equipment.

What to do in an emergency
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 front (or 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. Always follow these emergency tow-
ing precautions:
• Place the ignition switch in the
ACC position so the steering
wheel is not locked. (if equipped)
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 inch
(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.
OTLE068029
The driver must be in the vehi-
cle for steering and braking
operations when the vehicle is
being towed. Passengers other
than the driver must not be in
the vehicle.
