2016 Hyundai Equus check engine

When emergently towing your vehi-
cle without a wheel dolly:
1.Set the Engine Start/Stop Button inthe ACC position.
2.Place the shift lever in N (Neutral).
3.Release the parking brake. When the ECS malfunction indica-
tor illuminates with no air in the
suspension, the vehicle height is
very low. Thus, do not drive the
vehicle to protect it from any pro-
jections on the ground. Tow your
vehicle to an authorized EQUUS
dealer and have the system
checked. You should tow the vehi-
cle as shown in the illustration.
When loading the vehicle onto the
tow truck, the loading slope angle (1)
should be less than 6°.

What to do in an emergency06
Do not tow the vehicle, drag-
ging the rear wheels on the
ground. This may damage the
vehicle.
Do not tow with a sling-type equipment. Use a wheel lift or
a flatbed.
CAUTION
Failure to set the shift lever in
N(Neutral) may cause internal
damage of the transmission.

Use a towing strap, which is 16 feet(5 m) or shorter. Tie a white or red
cloth (about 12 inches (30 cm)
wide) in the middle of the strap for
the better visibility.
Drive carefully not to loosen the towing strap, while towing.
Information
Emergency towing is illegal in some
states. Contact an authorized EQUUS
dealer and tow the vehicle.
Emergency towing precautions
Set the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with extraforce, because the brake perform-
ance may be reduced.
Put extra force into the steering wheel operation, because the
power steering system may be dis-
abled.
Driving down a long slope may overheat the brakes, reducing the
brake performance. Stop driving at
intervals and cool off the brake
system. - Automatic transmission
When the car is towed, dragging
all four wheels on the ground, it
should be done only in a forward
direction. Be sure to set the shift
lever in N(Neutral). Unlock the
steering wheel by pressing the
Engine Start/Stop button to the
ACC position. A driver must be
in the towed vehicle to operate
both the steering wheel and
brakes.
To avoid a serious damage to the automatic transmission
while towing, limit the vehicle
speed to 10 mph (15 km/h) and
drive shorter than 1 mile (1.5
km).
Before towing, check any fluid lick of the automatic transmis-
sion. When it leaks, flatbed
equipment or a towing dolly
must be used.

These Owner Maintenance Checklists
are mostly uncovered by your vehicle
warranties. Thus, you may charges
you for expenses of labor, parts or
lubricants.
Owner's maintenance sched-
ule
While refueling:
Check the engine oil level.
Check coolant level in coolantreservoir.
Check the windshield washer fluid level.
Check for any low or under-inflated tires.
While driving:
Check for any changes in theexhaust sounds or the smells.
Check for any steering wheel vibra- tion. Check whether you feel more
tightness or looseness of the steer-
ing wheel.
Check for any slight tilting, or “pulls” to one side, while driving on
a flat surface.
Check for any unusual sounds, tilt- ing, a braking distance, or “hard-to-
push” brake pedal while stopping.
Check the transmission fluid level upon experiencing a skid or a sud-
den transmission gear change.
Check the P(Park) function of the auto transmission.
Check the parking brake.
Check for any fluid leak (water dripping from the A/C while or after
the normal driving).
At least once a month:
Check the coolant level in theengine coolant reservoir.
Check the operation of all exterior lights, such as the stoplights, turn
signals and hazard warning flash-

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.

Maintenance
The use of an unauthorized fluid
may result in transmission mal-
function and failure. Use only the
authorized automatic transmis-
sion fluid. (Refer to “Recommended
lubricants and capacities” in the
chapter 8.)
Brake hoses and lines
Confirm the proper installation, and
check for any frictions, cracks, dete-
rioration and leakage. If necessary,
immediately replace any deteriorated
or damaged parts.
Brake fluid
Check the brake fluid level. The level
should be between “MIN” and “MAX”
marks on the reservoir. Use only the
hydraulic brake fluid, which meet the
requirements of the DOT3/DOT4
specifications.
Brake discs, pads, calipers
and rotors
Check the pads and the disc for any
excessive wear-out, and inspect
calipers for any fluid leakage.
Exhaust pipe and muffler
Inspect the exhaust pipes, muffler
and hangers for any cracks, deterio-
rations, or damages. Start the
engine, and listen carefully for any
gas leaking noise. If necessary, tight-
en connections or replace the dam-
aged parts.
Suspension mounting bolts
Check the suspension connections
for any looseness or damage. If nec-
essary, retighten the bolt to the spec-
ified torque.
Steering gear box, linkage &
boots/lower arm ball joint
After stopping the vehicle and turn-
ing off the engine, confirm the steer-
ing locking (tightening).
Check the bends for any linkage or
damage. Check the dust boots and
ball joints for any deterioration,
cracks, or damage. If necessary,
replace the damaged parts.
Power steering pump, belt and
hoses
Check the power steering pump and
hoses for any leakage or damage. If
necessary, immediately replace any
damaged or leaking parts. Inspect
the power steering belt (or drive belt)
for any cuts, cracks, excessive wear-
out, oil saturation or looseness. If
necessary, replace or adjust the
damaged part.
Drive shafts and boots
Check the drive shafts, boots and
clamps for any cracks, deterioration,
or damage. If necessary, replace or
grease the damaged part.
Air conditioning refrigerant
Check the air conditioning lines and
connections for any leakage or dam-
age.

Checking the engine oil level
1. Be sure the vehicle is on levelground.
2. Start the engine and allow it to reach a normal operating temper-
ature.
3. Turn the engine off and wait for the oil fluctuation to stabilize in the oil
pan (approximately 5 minutes).
4. Pull the dipstick out, wipe it clean, and re-insert it fully.
5. Pull the dipstick out again and check the level. The level should
be between F and L. Do not overfill the engine oil.
This may damage the engine.
while adding or changing it. If
you spill out the engine oil in the
engine compartment, immedi-
ately wipe it off.
When it is near to or at L, add the
engine oil to bring it up to F. Do not
overfill it.
Use a funnel to prevent oil spillage
over the engine components.
Use only the authorized engine oil. (Refer to “Recommended lubricantsand capacities” in the chapter 8.)
