What to do in an emergency

If towing is necessary, we recommend
you to have it done by an authorised
HYUNDAI dealer or a commercial tow
truck service.
If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed using a cable or chain
secured to the emergency towing hook
under the front/rear of the vehicle. Use
extreme caution when towing the vehicle.
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 dis-
tance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
Do not use the tow hooks to pull a vehi-
cle out of mud, sand or other condi-
tions from which the vehicle cannot be
driven out under its own power.
Avoid towing a vehicle heavier than the vehicle doing the towing.
The drivers of both vehicles should communicate with each other frequent-
ly. Before emergency towing, check that
the hook is not broken or damaged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force.
To avoid damaging the hook, do not pull from the side or at a vertical angle.
Always pull straight ahead.
WARNING
Use extreme caution when towing
the vehicle.
driving manoeuvres which would
place excessive stress on the
emergency towing hook and tow-
ing cable or chain. The hook and
towing cable or chain may break
and cause serious injury or dam-
age.
If the disabled vehicle is unable to be moved, do not forcibly con-
tinue the towing. Contact an
authorised HYUNDAI dealer or a
commercial tow truck service for
assistance.
Tow the vehicle as straight ahead as possible.
Keep away from the vehicle dur- ing towing.CAUTION
Attach a towing strap to the tow
hook.
Using a portion of the vehicle other than the tow hooks for tow-ing may damage the body of yourvehicle.
Use only a cable or chain specifi- cally intended for use in towingvehicles. Securely fasten thecable or chain to the towing hook provided.

What to do in an emergency
Use a towing strap less than 5 m (16feet) long. Attach a white or red cloth (about 30 cm (12 inches) wide) in the
middle of the strap for easy visibility.
Drive carefully so that the towing strap is not loosened during towing.
Emergency towing precautions
Place the ignition switch in ACC so thesteering wheel isn’t locked.
Place the transaxle shift lever in N (Neutral).
Release the parking bake.
Press the brake pedal with more force than normal since you will have
reduced brake performance.
More steering effort will be required because the power steering system
will be disabled.
If you are driving down a long hill, the brakes may overheat and brake per-
formance will be reduced. Stop often
and let the brakes cool off.

CAUTION - Automatic
transaxle
If the car is being towed with all four wheels on the ground, it can
be towed only from the front. Besure that the transaxle is in neu-tral. Be sure the steering isunlocked by placing the ignition
switch in the ACC position. Adriver must be in the towed vehi- cle to operate the steering and
brakes.
To avoid serious damage to the automatic transaxle, limit thevehicle speed to 15 km/h (10 mph)and drive less than 1.5 km (1
mile) when towing.
Before towing, check for automat- ic transaxle fluid leak under yourvehicle. If the automatic transaxle fluid is leaking, a flatbed equip-
ment or towing dolly must beused.

Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning andcaution statements that appear on thelabel.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughlyand frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are keptclear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
APPEARANCE CARECAUTION
Do not use strong soap, chemical
detergents or hot water, and do
not wash the vehicle in direct sunlight or when the body of thevehicle is warm.
Be careful when washing the side windows of your vehicle.Especially, with high-pressurewater, water may leak through the windows and wet the interior.
To prevent damage to the plastic parts, do not clean with chemicalsolvents or strong detergents.
WARNING - Wet brakes
After washing the vehicle, test the
brakes whilst driving slowly to see
if they have been affected by water.
If braking performance is impaired,
dry the brakes by applying them
lightly whilst maintaining a slow
forward speed.

Bright-metal maintenance
To remove road tar and insects, use a
tar remover, not a scraper or other
sharp object.
To protect the surfaces of bright-metal parts from corrosion, apply a coating of
wax or chrome preservative and rub to
a high luster.
During winter weather or in coastal areas, cover the bright metal parts with
a heavier coating of wax or preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated rusting can
occur on underbody parts such as the
fuel lines, frame, floor pan and exhaust
system, even though they have been
treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Payspecial attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. The
lower edges of doors, rocker panels, and
frame members have drain holes that
should not be allowed to clog with dirt;
trapped water in these areas can cause
rusting.WARNING
After washing the vehicle, test the
brakes whilst driving slowly to see
if they have been affected by water.
If braking performance is impaired,
dry the brakes by applying them
lightly whilst maintaining a slow
forward speed.
