Engine Coolant/Liquid-Cooled
Intercooler Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic Transmission Fluid
Automatic transmission fluid should
not be checked under normal usage
conditions, the Automatic transmission
fluid should be changed by an authorized
retailer of Genesis Branded products
according to the maintenance schedule.
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction and
failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended Lubricants and
Capacities” section in chapter 2.)
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to DOT
4 specification.
Brake Discs, Pads, Calipers and
Rotors
Check the pads, the disc, and the rotor
for any excessive wear-out. Inspect
calipers for any fluid leakage
Exhaust Pipe and Muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks,
deterioration, or damage. Start
the engine and listen carefully for
any exhaust gas leakage. Tighten
connections or replace parts as
necessary.
Propeller Shaft
Check the propeller shaft, boots, clamps,
rubber couplings and center-bearing
rubber for cracks, deterioration, or
damage. Replace any damaged parts
and if necessary, repack the grease.

Maintenance

WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.
Excessive speed, under-inflation,
over-inflation, or excessive loading,
either separately or in combination,
can cause heat build-up and
possible sudden tire failure. This
may cause loss of vehicle control
resulting in an accident.
Tire Terminology and Definitions
Air pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory weight
This means the combined weight
of optional accessories. Some
examples of optional accessories
are automatic transmission, power
seats, and air conditioning.
Aspect ratio
The relationship of a tire’s height to
its width.
Belt
A rubber coated layer of cords that
is located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.Bias ply tire
A pneumatic tire in which the plies are
laid at alternate angles less than 90
degrees to the centerline of the tread.
Cold tire pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT markings
A code molded into the sidewall
of a tire signifying that the tire
is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric
designator which can also identify
the tire manufacturer, production
plant, brand and date of production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the
Front Axle.
GAWR RR
Gross Axle Weight Rating for the
Rear axle.
