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.
Information
When the engine is automatically started
by ISG system, warning lights (i.e. ABS,
ESC, ESC OFF, EPS, and parking brake
warning light) may illuminate for a few
seconds due to low battery voltage.
However, it does not indicate a
malfunction with ISG system.
ISG System Operation
Prerequisite for activation
ISG system operates in the following
situations.
• The driver's seatbelt is fastened
• The driver's door and hood are closed
• The battery sensor is activated and
the battery is sufficiently charged
• Outside temperature is not too low or
too high
• The vehicle is driven over a constant
speed and stops
• The climate control system satisfies
the conditions
• The vehicle is sufficiently warmed up
• ISG related parts are working properly
• The incline is gradual
• The steering wheel is turned less than
180 degrees and then the vehicle
stops
Information
ISG system is not activated, when the
prerequisites to activate the ISG system
are unsatisfied. If this occurs, the ISG
OFF button indicator illuminates, and the
Auto Stop (
) indicator illuminates in
yellow on the instrument cluster.
When the Auto Stop (
) indicator stays
on the instrument cluster, have the system
inspected by an authorized retailer of

stopped automatically when both of the
following occurs:
1. Vehicle speed decreases to 0mph (0
km/h) full stop condition.
2. Brake pedal is depressed and gear is
in D (Drive) or N (Neutral).
The Auto Stop (
) indicator illuminates
in green on the instrument cluster, when
the engine stops.

Idle stop cannot reoccur again until the
vehicle speed goes above 3 mph (5 km/h)
and then returns again to the automatic
stop conditions as previously mentioned.

Chain Installation
When installing AutoSock® (fabric
snow chain), follow the manufacturer's
instructions and mount them as tightly
as possible. Drive slowly (less than 20
mph (30 km/h)) with AutoSock® installed.
If you hear the fabric snow chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the AutoSock® as soon as you begin
driving on cleared roads.
When mounting AutoSock®, 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 tire chains.
NOTICE
When using AutoSock® (fabric snow
chain):
• Wrong size fabric snow chains or
improperly installed fabric snow
chains can damage your vehicle's
brake lines, suspension, body and
wheels.
• If you hear noise caused by fabric
snow chains contacting the body,
retighten the fabric snow chains to
prevent contact with the vehicle
body.
• To prevent body damage, retighten
the fabric snow chains after driving
0.3~0.6 miles (0.5~1.0 km).
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.

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 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 WILL NOT
START
• 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.
See instructions for “Jump Starting”
provided in this chapter.
• Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, call an
authorized retailer of Genesis Branded
products for assistance.
NOTICE
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.
