Information
If the indicator (white) is activated
from the previous ignition cycle, the
system will turn ON without any addi-
tional control. If you press the LKA
switch again, the indicator on the clus-
ter goes off.
LKA system operation
• To see the LKA system screen on
the LCD display in the cluster,
select Assist mode ( ). For more
details, refer to "LCD Display
Modes" in chapter 3.
• If vehicle speed is over 40 mph (64
km/h) and the system detects lane
markers, the color changes from
gray to white.• If your vehicle departs from the
projected lane in front of you, the
LKA system operates as follows:
1. A visual warning appears on the
cluster LCD display. Either the left
lane marker or the right lane
marker in the cluster LCD display
will blink depending on which
direction the vehicle is veering.
Also, the steering wheel will
vibrate along with a warning
sound.
2. The LKA system will will help con-
trol the vehicle's steering to pre-
vent the vehicle from crossing the
lane maker in below conditions.
- Vehicle speed is over 40 mph (64
km/h)
- When driving, the vehicle is
located between both lanes nor-
mally.
- The steering wheel is not turned
suddenly.
When lane markers are detected and
all the conditions to activate the LKA
system are satisfied, a LKA system
indicator light ( ) will change
from white to green. This indicates
that the LKA system is in the
ENABLED state and the steering
wheel will be controlled.

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
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.
