3. Install the towing hook by turning it

clockwise into the hole until it is
fully secured.

4. Remove the towing hook and

install the cover after use.

Emergency towing

If towing is necessary, have it
done by an authorized Kia 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 under the front (or 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 distance and at low speed.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
• Do not use the tow hooks to pull a

vehicle out of mud, sand or other
conditions 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 fre-
quently.

What to do in an emergency

• Attach a towing strap to the tow

hook.

• Use only a cable or chain specifical-

ly intended for use in towing vehi-
cles. Securely fasten the cable or
chain to the towing hook provided.

• Before emergency towing, check if

the hook is not broken or damaged.

• Fasten the towing cable or chain

securely to the hook.

• Do not jerk the hook. Apply it

steadily and with even force.

• To avoid damaging the hook, do not

pull from the side or at a vertical
angle. Always pull straight ahead.

• Use a towing strap less than 16

feet (5 m) long. Attach a white or
red cloth (about 12 inches (30 cm)
wide) in the middle of the strap for
easy visibility.

• Drive carefully so that the towing

strap is not loosened during tow-
ing.

CAUTION

Using a portion of the vehicle
other than the tow hooks for
towing may damage the body of
your vehicle.

WARNING

- Emergency

Towing Precautions

Use extreme caution when tow-
ing the vehicle.
• Avoid sudden starts or erratic

driving maneuvers which
would place excessive stress
on the emergency towing hook
and towing cable or chain. The
hook and towing cable or
chain may break and cause
serious injury or damage.

• If the disabled vehicle is

unable to be moved, do not
forcibly continue the towing.
We recommend that you con-
tact an authorized Kia dealer
or a commercial tow truck
service for assistance.

• Tow the vehicle as straight

ahead as possible.

• Keep away from the vehicle

during towing.

OJFH065047L

What to do in an emergency

Emergency towing precautions

• Turn the ignition switch to ACC so

the steering 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 steer-
ing system will be disabled.

• If you are driving down a long hill,

the brakes may overheat and brake
performance will be reduced. Stop
often and let the brakes cool off.

• If the car is being towed with all

four wheels on the ground, it can
be towed only from the front. Be
sure that the transaxle is in neutral.
Be sure the steering is unlocked by
placing the ignition switch in the
ACC position. A driver must be in
the towed vehicle to operate the
steering and brakes.

CAUTION

Automatic
transaxle

• To avoid serious damage to

the automatic transaxle, limit
the vehicle speed to 10 mph
(15 km/h) and drive less than 1
mile (1.5 km) when towing.

• Before towing, check the auto-

matic transaxle for fluid leaks
under your vehicle. If the auto-
matic transaxle fluid is leak-
ing, flatbed equipment or a
towing dolly must be used.

What to do in an emergency

IF AN ACCIDENT OCCURS

✽

NOTICE

Any gas or electrolyte leakage from
your vehicle is not only poisonous
but also flammable. Upon witness-
ing one of those, open the windows,
and remain a safe distance from the
vehicle out of the road. Immediately
contact an authorized Kia dealer
and advise them that a hybrid vehi-
cle is involved.

• If you need towing, refer to

"Towing" in the previous pages.

• When the vehicle is severely dam-

aged, remain a safe distance of 50
feet (15 meter) or more between
your vehicle and other
vehicles/flammables.

• If a small scale fire occurs, use a

fire extinguisher (ABC, BC) that is
meant for electrical fires.
If it is impossible to extinguish the
fire in the early stage, remain a
safe distance from the vehicle and
immediately call 911. Also, advise
them that a hybrid vehicle is
involved.
If the fire spreads to the high volt-
age battery, large amount of water
is needed to put out the fire.
Using small amount of water or fire
extinguishers not meant for electri-
cal fires could cause serious injury
or death from electrical shocks.

WARNING

- High voltage

components

• For your safety, do not touch

high voltage cables, connec-
tors and package modules.
High voltage components are
orange in color.

• Exposed cables or wires may

be visible inside or outside of
the vehicle. Never touch the
wires or cables, because an
electrical shock, an injury, or a
death may occur.

WARNING

- Submersion

in water

Do not touch your vehicle if it
has been submerged in water.
The high-voltage battery may
cause shock or may catch fire.
Immediately contact the author-
ities and advise them of the
condition of your vehicle and
that a hybrid vehicle is involved.

• Check for vibrations in the steering

wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.

• 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 transaxle occurs,
check the transaxle fluid level.

• Check the automatic transaxle P
