Driving your vehicle
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized retailer of Genesis
Branded products and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear in P and block the
rear wheels so the car cannot roll.
Then release the parking brake.
Do not let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering compo-
nents is not obstructed.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

What to do in an emergency
The hazard warning flasher serves
as a warning to other drivers to exer-
cise extreme caution when approach-
ing, overtaking, or passing your vehi-
cle.
It should be used whenever emer-
gency repairs are being made or
when the vehicle is stopped near the
edge of a roadway.
To turn the hazard warning flasher
on or off, press the hazard warning
flasher button. The button is located
in the center fascia panel. Both the
left and right turn signal lights will
flash simultaneously.
• The hazard warning flasher oper-
ates whether your vehicle is run-
ning or not.
• The turn signals do not work when
the hazard flasher is on.
If the Engine Stalls While
Driving
• Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place.
• Turn on your hazard warning flash-
er.
• Try to start the engine again. If your
vehicle will not start, contact an
authorized retailer of Genesis
Branded products or seek other
qualified assistance.
If the Engine Stalls at a
Crossroad or Crossing
If the engine stalls at a crossroad or
crossing, if safe to do so, move the
shift lever to the N (Neutral) position
and then push the vehicle to a safe
location.

If you Have a Flat Tire While
Driving
If a tire goes flat while you are driv-
ing:
• Take your foot off the accelerator
pedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
• When the vehicle is stopped, press
the hazard warning flasher button,
shift the gear to P (Park), apply the
parking brake, and press the
Engine Start/Stop button to the
OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
• When changing a flat tire, follow
the instructions provided later in
this chapter.If the Engine Doesn't Turn
Over or Turns Over Slowly
• Be sure to shift the gear to N
(Neutral) or P (Park). The engine
starts only when the gear is in N
(Neutral) or P (Park).
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle.See instructions for
"Jump Starting" provided in this
chapter.
Push or pull starting the vehicle
may cause the catalytic converter
to overload which can lead to
damage to the emission control
system.
If the Engine Turns Over
Normally but Doesn't Start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized retailer of Genesis Branded
products.

What to do in an emergency
Jump starting can be dangerous if
done incorrectly. Follow the jump
starting procedure in this section to
avoid serious injury or damage to
your vehicle. If in doubt about how to
properly jump start your vehicle, we
strongly recommend that you have a
service technician or towing service
do it for you.
JUMP STARTING
To prevent SERIOUS INJURY or
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery:
Always read and follow
instructions carefully
when handling a battery.
Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks, or
smoking materials away
from the battery.
Hydrogen is always pres-
ent in battery cells, is
highly combustible, and
may explode if ignited.
Keep batteries out of
reach of children.
Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
• When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.
• Do not attempt to jump start
your vehicle if your battery is
frozen.
• NEVER attempt to recharge
the battery when the vehicle's
battery cables are connected
to the battery.
• The electrical ignition system
works with high voltage.
NEVER touch these compo-
nents with the engine running
or when the Engine Start/Stop
button is in the ON position.

your vehicle by push-starting.
Jump starting procedure
Information
Your vehicle has a battery in the trunk
compartment, but when you jump
start your vehicle, use the jumper ter-
minal in the engine compartment.
1. Position the vehicles close enough
that the jumper cables will reach,
but do not allow the vehicles to
touch.
2. Avoid fans or any moving parts in
the engine compartment at all
times, even when the vehicles are
turned off.
3. Turn off all electrical devices such
as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brakes. Turn
both vehicles OFF.

rect battery or jumper terminals
or the correct ground. Do not
lean over the battery when mak-
ing connections.
11. Start the engine of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
12. Keep your vehicle operating for at
least 30 minutes at idle or driving
to assure your battery receives
enough charge to be able to start
on its own after the vehicle is
shut off. A complete dead battery
may require as long as 60 min-
utes runtime to fully recharge it. If
vehicle is run for less, the battery
may not restart. If you continue to
have problem, have your author-
ized retailer of Genesis Branded
products test the battery.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized retailer of Genesis
Branded products.Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the
jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper
cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the
jumper cable from the red, positive
(+) jumper terminal of your vehicle

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 soon
as it is safe to do so.
2. Shift the gear to P (Park) and set
the parking brake. If the air condi-
tioning 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 retailer
of Genesis Branded products for
assistance.
IF THE ENGINE OVERHEATS
While the engine is
running, keep hands,
clothing and tools
away from the moving
parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
