during maintenance, do so
out doors or in an area with
plenty of ventilation.
• Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.

Maintenance
Valve Clearance (3.3 T-GDI)
Inspect for excessive valve noise
and/or engine vibration and adjust if
necessary. Have an authorized retail-
er of Genesis Branded products per-
form the operation.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic Transmission Fluid
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized retailer of Genesis
Branded products in accordance to
the scheduled maintenance at the
beginning of this chapter.
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 and
you should not judge the need to
replace the fluid based upon the
changed color.
The use of a non-specified fluid
could result in transmission mal-
function and failure.
Use only the specified automatic
transmission fluid (refer to
"Recommended Lubricants and
Capacities" in chapter 8).

Maintenance
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. If possible, block the
wheels.
3. Turn the engine on and allow the
engine to reach normal operating
temperature.
4. Turn the engine off and wait about
five minutes for the oil to return to
the oil pan.
5. Pull the dipstick out, wipe it clean,
and re-insert it fully.
6. Pull the dipstick out again and
check the level. The level should
be between F and L.7. If it is near or at L, add enough oil
to bring the level to F.
Use only the specified engine oil
(refer to "Recommended
Lubricants and Capacities" in
chapter 8).
To prevent damage to your
engine:
• Do not overfill with engine oil.
Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
• Do not spill engine oil when
adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately.

Checking the Brake Fluid
Level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.
If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake system checked by an
authorized retailer of Genesis
Branded products.• Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result.
• Brake fluid, which has been
exposed to open air for an
extended time should NEVER be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
• Do not use the wrong kind of
brake fluid. A few drops of min-
eral based oil, such as engine
oil, in your brake system can
damage brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
i
NOTICE
BRAKE FLUID
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
retailer of Genesis Branded
products.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.
