Driving your vehicle
Remove any dirt, snow, or debris and
clean the radar sensor lens cover
before operating the AEB system.
The AEB may not properly operate in
an area (e.g. open terrain), where
any substances are not detected
after turning ON the engine.
Do not apply foreign objects such as a bumper sticker or a
bumper guard near the radar
sensor. Doing so may adversely
affect the sensing performance
of the radar.
Always keep the radar sensor and lens cover clean and free of
dirt and debris.
Use only a soft cloth to wash the vehicle. Do not spray pressur-
ized water directly on the sensor
or sensor cover.
Be careful not to apply unneces- sary force on the radar sensor or
sensor cover. If the sensor is
forcibly moved out of proper
alignment, the AEB system may
not operate correctly. In this
case, a warning message may
not be displayed. Have the vehi-
cle inspected by an authorized
Dealer of Genesis Brand
Products.
If the front bumper becomes damaged in the area around the
radar sensor, the AEB system
may not operate properly. Have
the vehicle inspected by an
authorized Dealer of Genesis
Brand Products.
Use only genuine Genesis Brand parts to repair or replace
a damaged sensor or sensor
cover. Do not apply paint to the
sensor cover.

The severe weather conditions of winter quickly wear out tires and cause
other problems. To minimize winter driving problems, you should take the fol-
lowing suggestions:
Snow or Icy Conditions
You need to keep sufficient distance between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid acceleration, sudden brake applica-
tions, and sharp turns are potentially very hazardous practices. During decel-
eration, use engine braking to the fullest extent. Sudden brake applications on
snowy or icy roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it may be necessary to use snow tires or
to install tire chains on your tires.
Always carry emergency equipment. Some of the items you may want to carry
include tire chains, tow straps or chains, a flashlight, emergency flares, sand,
a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a
blanket, etc.
We recommend you use snow tires when road temperature is below 45°F
(7°C). Refer to the below chart, and mount the recommended snow tire for
your vehicle.
If you mount snow tires on your vehicle, make sure to use the same inflation
pressure as the original tires. However, if you mount 245/45R19 size tire on
the rear, the tire inflation pressure should maintain 35psi. Mount snow tires on
all four wheels to balance your vehicle's handling in all weather conditions.
The traction provided by snow tires on dry road may not be as high as your
vehicle's original equipment tires. Check with the tire dealer for maximum
speed recommendations.
Information
Do not install studded tires without first checking local, state and municipal reg-
ulations for possible restrictions against their use.

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).
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 authorized
Dealer of Genesis Brand Products.

What to do in an emergency
Information
If any of the below happens, have the
system checked by an authorized
Dealer of Genesis Brand Products.
1. The Low Tire Pressure Telltale/TPMS Malfunction Indicator does
not illuminate for 3 seconds when
the Engine Start/Stop button is
turned to the ON position or engine
is running.
2. The TPMS Malfunction Indicator remains illuminated after blinking
for approximately 1 minute.
3. The Low Tire Pressure Position Telltale remains illuminated.

Display with
Position
Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.
If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, 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 LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.

Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
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 transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

Battery Recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes dischargedin a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.
AGM battery
Absorbent Glass Matt (AGM) batteries are maintenance-free
and we recommend that the
AGM battery be serviced by an
authorized Dealer of Genesis
Brand Products. For charging
your AGM battery, use only fully
automatic battery chargers that
are specially developed for AGM
batteries.
When replacing the AGM bat- tery, we recommend that you
use parts for replacement from
an authorized Dealer of Genesis
Brand Products.
Do not open or remove the cap on top of the battery. This may
cause leaks of internal elec-
trolyte that could result in
severe injury.
NOTICE
Always follow these instruc-
tions when recharging your
vehicle's battery to avoid the
risk of SERIOUS INJURY or
DEATH from explosions or acid
burns:
Before performing mainte-nance or recharging the bat-
tery, turn off all accessories
and press the Engine Start/
Stop button to the OFF posi-
tion.
Keep all flames, sparks, or smoking materials away from
the battery.
Always work outdoors or in an area with plenty of ventilation.
Wear eye protection when checking the battery during
charging.
The battery must be removed from the vehicle and placed in
a well ventilated area.
Watch the battery during charging, and stop or reduce
the charging rate if the battery
cells begin boiling violently.
