When towing your vehicle in an
emergency without wheel dollies :
1. Place the Engine Start/Stop but-ton in the ACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.Removable towing hook
1. Open the trunk, and take the tow- ing hooks out from the tool case. 2. Open the cover by pressing the
lower part on the front bumper.
3. Install the towing hook by rotating it in a clock-wise direction until it is
securely installed.
4. After use, remove the towing hook and close the cover.
Failure to place the transmis-
sion shift lever in N (Neutral)
may cause internal damage to
the transmission.

What to do in an emergency
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 should be done only on a
solid ground for a short distance and
at a low speed.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Always follow these emergency tow-
ing precautions:
Place the Engine Start/Stop button
in the ACC 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.

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 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.
WARNING

Maintenance
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
For more information on checking
the pads or lining wear limit, refer to
the HYUNDAI web site.
(http://ser
vice.hyundai-motor.com)
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and the
hybrid system off, check for exces-
sive free-play in the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Checking the engine oil level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on level ground in P (Park) with the park-
ing brake set and the wheels
blocked.
3. Turn the engine on and allow the engine to reach normal operating
temperature.
4. Turn the hybrid system off and wait about five minutes for the oil
to return to the oil pan.
5. Pull the dipstick out, wipe it clean, and re-insert it fully. 6. Pull the dipstick out again and
check the level. The level should
be between F and L.
7. If it is near or at L, add enough oil to bring the level to F. To prevent damage to your
engine:
Do not overfill with engine oil.
Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
Do not spill engine oil when adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately

Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
(Continued)Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause
loss of braking effectiveness,
steering) control, or traction.
ALWAYS replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire
pressure for your vehicle can
be found in this manual and on
the tire label located on the dri-
ver’s side center pillar. Always
use a tire pressure gauge to
measure tire pressure. Tires
with too much or too little
pressure wear unevenly caus-
ing poor handling.
Check the pressure of the
spare every time you check
the pressure of the other tires
on your vehicle.
