Vehicle Information, Consumer Information and Reporting Safety Defects
Recommended SAE Viscosity Number
CAUTION
Always be sure to clean the area around any filler cap, drain plug, or dipstick before
checking or draining any lubricant. This is especially important in dusty or sandy
areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick
areas will prevent dirt and grit from entering the engine and other mechanisms that
could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory lubrication in hot weather. Using oils of any
viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated
in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.

Cabin air filter
OHI048581L
A : Outside air,
B : Recirculated air,
C : Climate control air filter,
D : Blower,
E : Evaporator core,
F : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
We recommend that the cabin air filter
be replaced by an authorized retailer of
Genesis Branded products according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected at an
authorized retailer of Genesis Branded
products.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized retailer of Genesis Branded
products.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
NOTICE

[The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.

[The refrigerant system should be
serviced in a well-ventilated place.

[The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.

Automatic gear shift to P (Park)
The gear is shifted to P (Park)
automatically for safety reasons under
the following conditions:
-When the engine is turned off with
the gear in R (Reverse), D (Drive) or N
(Neutral).
-When the driver’s door is opened
with the engine running, the gear in R
(Reverse), D (Drive) or N (Neutral), the
seat belt unfastened and the vehicle
at a standstill.
-When the driver’s or front passenger’s
door is opened with the gear in N
(Neutral) and the vehicle is turned off.
In situations the gear must be in P (Park),
always check if the gear is shifted to P
(Park) by checking the cluster.R (Reverse)
Use this position to drive the vehicle
rearward.
ORS061005
To shift the gear to R (Reverse), rotate
the shift dial counterclockwise while
depressing the brake pedal.
The dial will vibrate each time it is
shiftedto R (Reverse). It is to prevent
incorrect dial shift or to notify the
driver the dialshift is in the R (Reverse)
position.
When the vehicle is stopped in the
R (Reverse) position, if you open
the driver's door with the seat belt
unfastened, the gear will automatically
shift to P (Park).
However, if the vehicle is in motion, the
gear may not automatically shift to P
(Park) to prevent automatic transmission
damage.
NOTICE
Always come to a complete stop before
shifting into or out of R (Reverse); you
may damage the transmission if you
shift into R (Reverse) while the vehicle is
in motion.

Limitations of the System
The predictive shift may have limited
operation in the following situations

[If you do not take the route guided in
the navigation, predictive shift may
not operate properly since the system
operates according to the navigated
route. Predictive shift will operate
properly again once the navigation
sets a new route.

[The navigation may reflect the real
time traffic condition and change the
route. If so, the predictive shift may
not correspond temporarily to the
current driving condition.

[If the destination is not set on the
navigation, predictive shift operates
according to the route which is most
likely to be taken. When driving
through roads such as a branch road,
predictive shift may not correspond to
the current driving condition until the
navigation sets a new route.

[While using the navigation app
through smart phone linked functions
such as Android Auto or Apple
CarPlay, predictive shift operates as
when the destination is not set in the
vehicle’s navigation.

[Predictive shift may not operate
properly in the following situations.
-Navigation system is not completely
booted.
-Real time GPS or map data has
errors, or the map data is not up to
date.
Checking Operation on the
Instrument Cluster
The operating condition of predictive
shift can be checked from the icons and
messages displayed on the instrument
cluster. If there are multiple conditions
detected, every related icon illuminates
but only the most important message
is displayed. The images and colors
of the messages may differ from the
description depending on the cluster
type.
CAUTION
Always be aware of the traffic and
road condition ahead. Checking the
instrument cluster while driving
may cause an accident.
When predictive shift is ready
ORS062039N
Refer to the following for icons displayed
when predictive shift is stand-by for use.

Rear Wheel Steering system in the
infotainment system after installing
snow chains, the snow chains can
damage your vehicle’s body or chassis
parts. When you hear the snow chain
hitting the vehicle, stop the vehicle and
check whether the snow chains are
installed properly and whether the Rear
Wheel Steering system is disabled.
Information

[Install AutoSock® (fabric snow chain)
only in pairs and on the rear tires.
It should be noted that installing
AutoSock (fabric snow chain) on the
tires will provide a greater driving
force, but will not prevent side skids.

[Do not install studded tires without
first checking local, state and municipal
regulations for possible restrictions
against their use.
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).

the wheel bolts in the order shown.
Double-check each wheel bolts until
they are tight. After changing tires,
have an authorized retailer of Genesis
Branded products tighten the wheel
bolts to their proper torque as soon
as possible. The wheel bolt should
be tightened to 101~116 lbf·ft (14~16
kgf·m).
If you have a tire gauge, check the
tire pressure (see “Tires and Wheels”
section in chapter 2 for tire pressure
instructions.). If the pressure is lower or
higher than recommended, drive slowly
to the nearest service station and adjust
it to the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations.
