2016 Hyundai Equus spark plugs replace

5-74
Driving your vehicle
An AutoSock, which is in the wrong size or is improperly
installed, may damage brake
lines, suspension, body and
wheels of your vehicle.
Stop driving and retighten the AutoSock, whenever there are
snapping sounds between the
vehicle and the AutoSock.
Use high quality ethylene gly-
col coolant
The cooling system of your vehicle is
filled with the high-quality ethylene
glycol coolant when being delivered.
It is the only type of coolant that your
vehicle is filled with, because it pre-
vents corrosion of the cooling sys-
tem, lubricates the water pump and
prevents freezing. Refill the cooling
system in accordance with your
maintenance schedule in the chapter
7. Before winter, check your coolant
to assure that the freezing point is
sufficiently lower than the expected
winter temperature.
Check battery and cables
The winter temperature increases
the battery consumption. Inspect the
battery and cables, as described in
the chapter 7. The battery charging
level can be checked by an author-
ized EQUUS dealer or in a service
station.
Change to "winter weight" oil,
if necessary
In some regions during the cold win-
ter, it is recommended to use the
"winter weight" oil with lower viscosi-
ty. For further information about this,
refer to the chapter 8. When you can-
not be sure about a type of winter
weight oil, consult an authorized
EQUUS dealer.
Check spark plugs and ignition
system
Inspect your spark plugs and, if nec-
essary, replace them. Also check all
ignition wirings and components for
any cracks, wear-out, and damage.
NOTICE
- Chain installation
When installing the AutoSock,
park the vehicle on level ground
away from other vehicles. Press
ON the Hazard Warning flasher
and place a warning triangle
behind your vehicle, if available.
Place the shift lever in P(Park),
set the parking brake and turn
OFF the engine, before
installing the AutoSock.
WARNING
- Tire chains
The use of the AutoSock may
adversely affect vehicle han-
dling.
Do not drive faster than the lower of the two - 20 mph (30
km/h) and the AutoSock manu-
facturer’s recommended
speed limit.
Drive carefully and avoid bumps, holes, sharp turns, and
other road hazards, which may
bounce the vehicle.
Avoid turning sharply or lock- ing the wheel brake.

Engine oil and filter
The engine oil and filter should be
changed at the interval, as specified
in the maintenance schedule. After
driving in severe conditions, you
should more frequently change oil
and filters.
Drive belts
Inspect all belts for any cut, crack,
excessive wear-out, or oil saturation.
If necessary, replace it.
Fuel filter
A clogged filter may limit the acceler-
ating function, damage the emission
system and cause other problems,
such as hard starting. When an
excessive amount of foreign sub-
stances accumulate in the fuel tank,
you should more frequently replace
the filter. After installing a new filter,
run the engine for several minutes,
and check for any leakage from the
connections. Fuel filters should be
installed by an authorized EQUUS
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for any leakage and
damage. Immediately have an
authorized EQUUS dealer replace
any damaged or leaking parts.
Vapor hose and fuel filler cap
Check the fuel lines, fuel hoses and
connections for any leakage and
damage. Immediately have an
authorized EQUUS dealer replace
any damaged or leaking parts.
Air cleaner filter
An authorized HYUNDAI air cleaner
filter is recommended.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check the cooling system compo-
nents, such as radiator, coolant
reservoir, hoses and connections, for
any leakage and damage. If neces-
sary, replace any damaged parts.
Coolant
The coolant should be changed at
the interval, as specified in the main-
tenance schedule.
Automatic transmission fluid
You do not need to check the auto-
matic transmission fluid, when driv-
ing under normal conditions.
However, after driving in severe con-
ditions, the fluid should be changed
by an authorized EQUUS dealer in
accordance with the maintenance
schedule, as specified in the begin-
ning of this chapter.
Information
The original color of the automatic
transmission fluid is red. However, as
you drive the vehicle, the color will
become darker. This is normal, and
you do not need to change the fluid
due to the changed color.
