What to do in an emergency
If you have a flat tire while
driving
If a tire goes flat while you are driving:
Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately 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 care-
fully 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,
move the shift lever into P (Park),
and apply the parking brake, and
place the Engine Start/Stop button
in 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 the shift lever is in N
(Neutral) or P (Park). The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
Check the battery connections to
be sure they are clean and tight.
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.
If the engine turns over nor-
mally 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.

Push or pull starting the vehicle
may cause the catalytic con-
verter to overload which can
lead to damage to the emission
control system.

7. Connect the jumper cables in the
exact sequence shown in the illus-
tration. First connect one jumper
cable to the red, positive (+)
jumper terminal of your vehicle (1).
8. Connect the other end of the
jumper cable to the red, positive
(+) battery/jumper terminal of the
assisting vehicle (2).
9. Connect the second jumper cable
to the black, negative (-) battery/
chassis ground of the assisting
vehicle (3).
10. Connect the other end of the sec-
ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals
or the correct ground. Do not lean
over the battery when making
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.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
(1).
Push-starting
Vehicles equipped with automatic
transmission cannot be push-start-
ed.
Follow the directions in this chapter
for jump-starting.

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. 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 retailer
of Genesis Branded products for
assistance.

6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, 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 retailer of
Genesis Branded products 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 retailer of Genesis Branded
products.
CAUTION
NEVER remove the
radiator cap, drain
plug and heater hose
connector cap while
the engine and radia-
tor are hot. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

✽
✽NOTICE
If any of the below happens, have
the system checked by an authorized
retailer of Genesis Branded prod-
ucts.
1. The Low Tire Pressure Telltale/
TPMS Malfunction Indicator
does not illuminate for 3 seconds
when the Engine Start/Stop but-
ton is turned to the ON position
or engine is running.
2. The TPMS Malfunction Indicator remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure Position Telltale remains illuminated.
Low tire pressure
telltale
Low tire pres-
sure position
and tire pres-
sure telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The Low Tire
Pressure Position Telltale will indi-
cate which tire is significantly under-
inflated by illuminating the corre-
sponding position light.
If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle's placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel. If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately
20 minutes at speed above 15.5 mph
(25 km/h)) until you have the low
pressure tire repaired and replaced
on the vehicle.
✽ ✽
NOTICE
The spare tire is not equipped with a
tire pressure sensor.

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. Use a towing cable or chain less
than 16 feet (5 m) long. Attach a
white or red cloth (about 12 inches
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable
or chain remains tight during tow-
ing.
Before towing, check the automat-
ic transmission for fluid leaks under
your vehicle. If the automatic trans-
mission fluid is leaking, flatbed
equipment or a towing dolly must
be used.
ODH067025N
To avoid damage to your vehicle
and vehicle components when
towing:
Always pull straight ahead
when using the towing hooks.
Do not pull from the side or at
a vertical angle.
Do not use the towing hooks
to pull a vehicle out of mud,
sand or other conditions from
which the vehicle cannot be
driven out under its own
power.
Limit the vehicle speed to 10
mph (15 km/h) and drive less
than 1 mile (1.5 km) when tow-
ing to avoid serious damage
to the automatic transmis-
sion.
