To prevent engine and/or trans-
mission overheating:
When towing a trailer on steepgrades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge toensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards "H" (HOT), pull
over and stop as soon as it is
safe to do so, and allow theengine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.
When towing a trailer, your vehi- cle speed may be much slower
than the general flow of traffic,
especially when climbing an
uphill grade. Use the right hand
lane when towing a trailer on an
uphill grade. Choose your vehi-
cle speed according to the max-
imum posted speed limit for
vehicles with trailers, the steep-
ness of the grade, and your trail-er weight.
(Continued)(Continued)
For vehicles equipped with the
Ecoshift dual clutch transmis-
sion, some extra precaution
should be taken when towing a
trailer. Due to the added load on
the transmission when towing a
trailer, the clutches may get hot
if the vehicle experiences exces-
sive upshifting and downshift-ing.
Under certain conditions, such
as repeated stop-and-go launch-
es on steep grades, the trans-
mission clutches may become
overheated. When the clutches
start to become overheated, the
transmission safe protection
mode logic is enabled. If the safe
protection mode logic is
enabled, the gear position indi-
cator on the cluster LCD display
blinks, a chime sounds, and a
warning message will appear.
(Continued)(Continued)
If the Ecoshift dual clutch trans-
mission starts to become over-
heated, the gear shift character-
istics may change. Gear shifts
may become more abrupt. If
continued operation while tow-
ing a trailer includes frequent
and continuous upshifts and
downshifts, the overheat warn-
ing message on the cluster LCD
display may illuminate. If this
occurs, stop the vehicle, apply
the brakes or shift the vehicle to
(P) Park, and allow the transmis-sion to cool.

Maintenance when trailer tow- ing
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particularattention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you’re trailering,
it’s a good idea to review these items
before you start your trip. Don't forget
to also maintain your trailer and
hitch. Follow the maintenance sched-
ule that accompanied your trailer and
check it periodically. Preferably,
inspect the vehicle and trailer at the
start of each day's driving. Inspect
the hitch mounting to make sure the
hitch is properly secured to the vehi-
cle. Inspect the trailer electrical
wiring to make sure brake lights, turn
signal lights, running lights, and haz-
ard lights are working properly.To prevent vehicle damage:
Due to higher load during
trailer usage, overheating
might occur on hot days or
during uphill driving. If the
coolant gauge indicates over-
heating, switch off the air con-
ditioner and stop the vehicle
in a safe area to cool down the
engine.
When towing check the auto- matic transmission fluid more
frequently.
(Note: This is not applicable
for vehicles equipped with the
Ecoshift dual clutch transmis-sion.)

What to do in an emergency

If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soonas it is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is com-ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off. 4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5. If engine coolant is leaking out, stop the engine immediately and
call the nearest authorized
HYUNDAI dealer for assistance.

While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as thecooling fan and drive
belt to prevent seri-
ous injury.

What to do in an emergency
6. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has beenlost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
Your vehicle is equipped with a pres-
surized coolant
reserve tank. NEVER
remove the coolant
reserve tank cap or the radiatordrain plug while the engine and
radiator are HOT. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while thepressure is released.
When you are sure all the pres-
sure has been released, contin-ue turning the cap counter-
clockwise to remove it.
