2016 Hyundai Equus water pump

Power brakes
Your vehicle is equipped with the
power-assisted brakes that automat-
ically adjust themselves in a normal
driving condition.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other rea-
sons, you can still stop your vehicle
by depressing the brake pedal hard-
er than you do in normal driving. A
braking distance, however, will be
longer.
When the engine is OFF, the reserve
brake power becomes partially
depleted each time the brake pedal
is depressed. Do not repeatedly
depress the brake pedal when the
power brake is automatically set.
Pump the brake pedal only when
necessary to maintain the steering
control on slippery surfaces.

- Brakes
Do not put your foot on the
brake pedal while driving. This
may abnormally increase the
brake temperatures, wear
down the brake lining/pad,
and increase the braking dis-
tances.
When driving down on a long or steep slope, shift to a lower
gear and avoid depressing the
brakes in a continuous man-
ner. Depressing brakes in a
continuous manner may over-
heat the brakes, resulting in a
temporary loss of braking per-
formance.
(Continued)
(Continued)
Wet brakes may impair thevehicle’s ability to safely slow
down. The vehicle may also be
swerved to one side when the
wet brakes are depressed.
Lightly depress the brakes to
verify whether the brakes are
wet and show the above
symptom. Always test your
brakes in this fashion after
driving through deep water.
To dry the wet brakes, lightly
depress the brakes, while
maintaining a safe driving
speed until the brake perform-
ance returns to normal.
Always confirm the positions of the brake and accelerator,
before driving. If you do not
so, you may be confused and
depress the accelerator
instead of the brake pedal. It
may cause a serious accident.

Hazardous driving conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take these
suggestions:
Drive cautiously and keep a longerbraking distance.
Avoid abrupt braking or steering. When your vehicle is stuck in snow,
mud, or sand, use the second
gear. Accelerate slowly to avoid
unnecessary spinning of the drive
wheels.
Put sand, rock salt, tire chains or other non-slip materials under the
drive wheels to provide additional
traction when being stuck in ice,
snow, or mud.

- ABS
Do not pump the brake pedal,
when your vehicle is equipped
with the ABS.
WARNING
- Downshifting
Downshifting with an automatic
transmission, while driving on
slippery surfaces, may cause an
accident. A sudden speed
change in driving may cause
the tires to skid. Be careful
when downshifting on a slip-
pery surface.
WARNING

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.
WARNING

When the temperature gauge indi-
cates engine overheating, you may
experience a loss of power, loud
pinging, or knocking. The engine is
probably too hot. If this happens, you
should:
1.Pull off the road and stop the vehi-cle as soon as it is safe to do so.
2.Place the shift lever in P(Park), and set the parking brake. When the
A/C is turned ON, turn it OFF.
3.When the engine coolant gushes out, or when steam comes out
from the hood, stop the engine. Do
not open the hood until the coolant
outrushing or steaming stops.
Even when there is no more
coolant outrushing, leave the
engine running and operate the
engine cooling fan. When the fan
does not operate, turn the engine
OFF.
4.Check whether the water pump drive belt is missing. When it is not,
check its tightening. When it seems
to be loose, check for any coolant
leaking from the radiator or hoses
underneath the vehicle. (When the
A/C is turned ON, cold-water drain-
ing is normal upon stopping the
vehicle.) 5.When the water pump drive belt is
broken, or when engine coolant
leaks out, immediately stop the
engine and contact the nearest
authorized EQUUS dealer for
assistance.
6.When you cannot find a cause, wait until the engine temperature
cools down. When there is serious
loss of engine coolant, carefully
add coolant into the reservoir to
bring the fluid level above the
halfway mark.
7.Be cautious and keep alert for fur- ther signs of overheating. When
finding further overheating signs,
contact an authorized EQUUS
dealer for assistance.

What to do in an emergency
While the engine is running,
keep hair, hands, and clothing
away from moving parts, such
as the fan and drive belts, in
order to prevent an injury.
WARNING
Do not remove theradiator cap, when the
engine is hot. This may
blow out the engine
coolant out of the
opening and cause a
serious burn.
WARNING
Serious loss of coolant indi-
cates a leakage in the cooling
system. This should be immedi-
ately checked by an authorized
EQUUS dealer.
