During that time, ABS will go through
self-diagnosis and the light will go off if
everything is normal. If the light stays on,
you may have a problem with your ABS.
Contact an authorized retailer of Genesis
Branded products as soon as possible.
WARNING
If the ABS () warning light is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, contact your authorized
retailer of Genesis Branded products as
soon as possible.
NOTICE
When you drive on a road having poor
traction, such as an icy road, and apply
your brakes continuously, ABS will be
active continuously and the ABS (
)
warning light may illuminate. Pull your
vehicle over to a safe place and turn the
vehicle off.
Restart the vehicle. If the ABS warning
light is off, then your ABS system is
normal.
Otherwise, you may have a problem
with your ABS system. Contact an
authorized retailer of Genesis Branded
products as soon as possible.
Information
When you jump start your vehicle because
of a drained battery, the ABS ()
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning. Have the battery
recharged before driving the vehicle.
Electronic Stability Control (ESC)
OJX1069037OJX1069037
Electronic Stability Control helps to
stabilize the vehicle during cornering
maneuvers.
ESC checks where you are steering and
where the vehicle is actually going. ESC
applies braking pressure to any one of
the vehicle's brakes and intervenes in the
engine management system to assist the
driver with keeping the vehicle on the
intended path. It is not a substitute for
safe driving practices. Always adjust your
speed and driving to the road conditions.

NOTICE
• NEVER install any accessories or
stickers on the front windshield, or
tint the front windshield.
• NEVER place any reflective objects
(i.e. white paper, mirror) over the
dashboard. Any light reflection may
prevent the system from functioning
properly.
• Pay extreme caution to keep the
camera dry.
• Never disassemble the camera
assembly, or apply any impact on the
camera assembly.
Information
We recommend that the system be
inspected by an authorized retailer of
Genesis Branded products when:
• The windshield glass is replaced.
• The front view camera or cover gets
damaged or replaced.

Check Electronic Suspension
When Electronically Controlled
Suspension with Road Preview is not
working properly, this warning message
will appear on the cluster LCD display. If
this occurs, have the system inspected
by an authorized retailer of Genesis
Branded products.
NOTICE
If the battery level is high or low,
Electronically Controlled Suspension
with Road Preview may not work
temporarily to protect the system. If this
occurs, ‘Check Electronic Suspension’
warning message will appear.
Limitations of the System
Electronically Controlled Suspension
with Road Preview always operates
while driving according to the vehicle’s
movement, and the preview function
starts to work when the front view
camera detects road conditions such as
speed bumps. Therefore, the preview
function is limited when there is an
extreme condition that the front view
camera may not work normally. In this
case, the electronic control suspension
function operates without the preview
function in accordance with vehicle
movement.

Idle Stop and Go helps reduce fuel
consumption by automatically shutting
down the engine, when the vehicle is
at a standstill (i.e. red stop light, stop
sign, and traffic jam) subject to certain
prerequisite conditions being satisfied as
listed below.
The engine is automatically started upon
satisfying the starting conditions.
ISG system is always active, when the
engine is running.

Chain Installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:
• Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 0.47 in. (12 mm) thick to prevent damage to the chain’s connection.
Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked by
an authorized retailer of Genesis Branded
products or in a service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity. In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, consult
an authorized retailer of Genesis Branded
products.
