Engine Oil and Filter
The engine oil and filter should be 
changed at the intervals specified in the 
maintenance schedule. If the vehicle 
is being driven in severe conditions, 
more frequent oil and filter changes are 
required.
Drive Belts
Inspect all drive belts for evidence 
of cuts, cracks, excessive wear or oil 
saturation and replace if necessary.
Drive belts should be checked 
periodically for proper tension and 
adjusted as necessary.
 Information
When you are inspecting the belt, turn the 
engine off.
Fuel Lines, Fuel Hoses and 
Connections
Check the fuel lines, fuel hoses and 
connections for leakage and damage. 
Have an authorized retailer of Genesis 
Branded products replace any damaged 
or leaking parts immediately.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should 
be inspected at those intervals specified 
in the maintenance schedule. Make sure 
a new vapor hose or fuel filler cap is 
correctly replaced.
Air Cleaner Filter
We recommend that the air cleaner filter 
be replaced by an authorized retailer of 
Genesis Branded products.
Spark Plugs
Make sure to install new spark plugs of 
the correct heat range.
Cooling System
Check cooling system components, such 
as radiator, coolant reservoir, hoses and 
connections for leakage and damage. 
Replace any damaged parts.
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.)
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

Maintenance
9-14
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.
Suspension Mounting Bolts
Check the suspension connections for 
looseness or damage. Retighten to the 
specified torque.
Steering Gear Box, Linkage & 
Boots/Lower Arm Ball Joint
With the vehicle stopped and the engine 
off, check for excessive free-play in the 
steering wheel. Check the linkage for 
bends or damage. Check the dust boots 
and ball joints for deterioration, cracks, 
or damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and clamps 
for cracks, deterioration, or damage. 
Replace any damaged parts and, if 
necessary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and 
connections for leakage and damage.

ENGINE OIL
Checking the Engine Oil Level
1. Follow all of the oil manufacturer’s 
precautions.
2. Be sure the vehicle is on the level 
ground in P (Park) with the parking 
brake set and the wheels blocked.
3. Turn the engine on and allow the 
engine to reach normal operating 
temperature.
4. Turn the engine off and wait about ten 
minutes for the oil to return to the oil 
pan.
5. Pull the dipstick out, wipe it clean, and 
re-insert it fully.

Checking the Engine Oil and 
Filter
Have the engine oil and filter changed by an authorized retailer of Genesis Branded 
products according to the Maintenance 
Schedule at the beginning of this 
chapter.
 WARNING
CALIFORNIA PROPOSITION 65 
WARNING
Engine oil contains chemicals known to 
the State of California to cause cancer, 
birth defects and reproductive harm.
Used engine oil may cause irritation or 
cancer of the skin if left in contact with 
the skin for prolonged periods of time.
Always protect your skin by washing 
your hands thoroughly with soap and 
warm water as soon as possible after 
handling used oil.

ENGINE COOLANT/LIQUID-COOLED INTERCOOLER COOLANT
The high-pressure cooling system has a 
reservoir filled with year-round antifreeze 
coolant. The reservoir is filled at the 
factory.
Check the antifreeze protection and 
coolant level at least once a year, at 
the beginning of the winter season and 
before traveling to a colder climate.
Checking the Coolant Level
		 
Page 559 of 632

Maintenance9-18
 Information
The coolant level is influenced by the 
engine temperature. Before checking or 
refilling the coolant, turn the engine off.
 WARNING
The electric motor for the cooling fan may continue to 
operate or start up when the 
engine is not running and can 
cause serious injury. Keep 
hands, clothing and tools away 
from the rotating fan blades of 
the cooling fan.
Always turn off the vehicle unless the 
vehicle has to be inspected with the 
engine on. Be cautious as the cooling 
fan may operate if the negative (-) 
battery terminal is not disconnected.
 WARNING
Make sure the coolant cap is properly 
closed after refilling coolant. Otherwise 
the engine could be overheated while 
driving.

Recommended coolant
• When adding coolant, use only 
deionized water, distilled water or soft 
water for your vehicle and never mix 
hard water in the coolant filled at the 
factory.
• An incorrect coolant mixture can 
result in severe malfunction or engine 
damage.
• The engine in your vehicle has 
aluminum engine parts and must be 
protected by an phosphate-based 
ethylene glycol coolant to prevent 
corrosion and freezing.
• Do not use alcohol or methanol 
coolant or mix them with the specified 
coolant.
• Do not use a solution that contains 
more than 60% antifreeze or less than 
35% antifreeze, which would reduce 
the effectiveness of the solution.
For mixing percentage, refer to the 
following table:
Ambient 
Temperature Mixture Percentage 
(volume)
Antifreeze Water
5°F (-15°C) 3565
-13°F (-25°C) 4060
-31°F (-35°C) 5050
-49°F (-45°C) 6040
 Information
If in doubt about the mix ratio, a 50% 
water and 50% antifreeze mix is the 
easiest to mix together as it will be the 
same quantity of each. It is suitable to 
use for most temperature ranges of -31°F 
(-35°C) and higher.
Changing Coolant
Have coolant changed by an authorized 
retailer of Genesis Branded products 
according to the Maintenance Schedule 
at the beginning of this chapter.
 WARNING
Do not use engine coolant or antifreeze 
in the washer fluid reservoir.
Engine coolant can severely obscure 
visibility when sprayed on the 
windshield and may cause loss of 
vehicle control resulting in an accident.
Engine coolant may also cause damage 
to paint and body trim.
NOTICE
To prevent damage to engine parts, put 
a thick towel around the engine coolant 
cap and/or inverter coolant cap before 
refilling the coolant to prevent the 
coolant from overflowing into engine 
parts, such as the alternator.
