2011 Hyundai Equus brake sensor

Safety features of your vehicle
60 3
• Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it to
“ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this "under-ride" situation
because deceleration forces that are
detected by sensors may be signifi-
cantly reduced by such “under-ride”
collisions.• Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide protection to the
occupants.
However, side impact and curtain air
bags may inflate when the vehicle is
rolled over by a side impact collision, if
the vehicle is equipped with side
impact air bags and curtain air bags.• Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated to one area and
the full force of the impact is not deliv-
ered to the sensors.

Features of your vehicle
• If you move the shift lever to the R
position with the engine start/stop but-
ton in the ON position and the parking
assist system in OFF, the parking
assist system will operate automatical-
ly. But it will turn off automatically,
when the vehicle speed exceeds than
20km/h.
✽NOTICE
It may not operate if it’s distance from
the object is already less than approxi-
mately 25 cm when the system is ON.
Types of warning sound
• When an object is 100 cm to 61 cm
from the rear bumper : Buzzer beeps
intermittently
• When an object is 60 cm to 31 cm from
the front or rear bumper : Buzzer
sounds two beeps intermittently
• When an object is within 30 cm of the
front or rear bumper : Buzzer sounds
continuously.
Non-operational conditions of
parking assist system
Parking assist system may not oper-
ate normally when:
1. Moisture is frozen to the sensor. (It will
operate normally when moisture
melts.)
2. Sensor is covered with foreign matter,
such as snow or water, or the sensor
cover is blocked. (It will operate nor-
mally when the material is removed or
the sensor is no longer blocked.)
3. Sensor is stained with foreign matter
such as snow or water. (Sensing range
will return to normal when removed.)
There is a possibility of parking
assist system malfunction when:
1. Driving on uneven road surfaces such
as unpaved roads, gravel, bumps, or
gradient.
2. Objects generating excessive noise
such as vehicle horns, loud motorcycle
engines, or truck air brakes can inter-
fere with the sensor.
3. Heavy rain or water spray.
4. Wireless transmitters or mobile
phones present near the sensor.
5. Sensor is covered with snow.
Detecting range may decrease when:
1. Outside air temperature is extremely
hot or cold.
2. Undetectable objects smaller than 1 m
and narrower than 14 cm in diameter.
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes,
chains or small poles.
2. Objects, which tend to absorb sensor
frequency such as clothes, spongy
material or snow.

Limitations of the system
The smart cruise control system may
have limits to its ability to detect distance
to the vehicle ahead due to road and traf-
fic conditions.
On curves
• On curves, the smart cruise control
system may not detect a moving vehi-
cle in your lane, and then your vehicle
could accelerate to the set speed. Also,
the vehicle speed will slow down when
the vehicle ahead is recognized sud-
denly.
• Select the appropriate set speed on
curves and apply the brakes or accel-
erator pedal if necessary.• Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and select
the appropriate set speed. Check to be
sure that the road conditions permit
safe operation of the smart cruise con-
trol.
OBH058030OBH058029
CAUTION
• Do not install accessories around
the sensor and do not replace the
bumper by yourself. It may inter-
fere with the sensor performance.
• Always keep the sensor and
bumper clean.
• To prevent sensor cover damage
from occurring, wash the car with
a soft cloth.
• Do not damage the sensor or sen-
sor area by a strong impact. If the
sensor moves slightly off posi-
tion, the smart cruise control sys-
tem will not operate correctly.
If this occurs, have your vehicle
checked by an authorized
HYUNDAI dealer as soon as pos-
sible.
• Use only a genuine HYUNDAI
sensor cover for your vehicle.

On inclines
• During uphill or downhill driving, the
smart cruise control system may not
detect a moving vehicle in your lane,
and cause your vehicle to accelerate to
the set speed. Also, the vehicle speed
will slow down when the vehicle ahead
is recognized suddenly.
• Select the appropriate set speed on
inclines and apply the brakes or accel-
erator pedal if necessary.
Lane changing
• A vehicle which moves into your lane
from an adjacent lane cannot be rec-
ognized by the sensor until it is in the
sensor's detection range.
• The sensor may not detect immediate-
ly when a vehicle cuts in suddenly.
Always pay attention to the traffic, road
and driving conditions.
• If a vehicle which moves into your lane
is slower than your vehicle, your speed
may decrease to maintain the distance
to the vehicle ahead.
• If a vehicle which moves into your lane
is faster than your vehicle, your vehicle
will accelerate to the selected speed.
Vehicle recognition
Some vehicles ahead in your lane cannot
be recognized by the sensor as follows:
- Narrow vehicles such as motorcycles or
bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-decel-
erating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as
trailers with no loads

Driving your vehicle
A vehicle ahead cannot be recognized
correctly by the sensor if any of following
occurs:
- When the vehicle is pointing upwards
due to overloading in the trunk
- While the steering wheel is operating
- When driving to one side of the lane
- When driving on narrow lanes or on
curves
Apply the brakes or accelerator pedal if
necessary.(Continued)
• The smart cruise control system
is not a substitute for safe driving
practices but a convenience
function only. It is the responsi-
bility of the driver to always
check the speed and the distance
to the vehicle ahead.
• Always be aware of the selected
speed and vehicle to vehicle dis-
tance.
• Always maintain sufficient brak-
ing distance and decelerate your
vehicle by applying the brakes if
necessary.
• As the smart cruise control sys-
tem may not recognize complex
driving situations, always pay
attention to driving conditions
and control your vehicle speed.
• For safe operation, carefully read
and follow the instructions in this
manual before use.WARNING
• The vehicle cannot be stopped by
using the smart cruise control
system.
If an emergency stop is neces-
sary, you must apply the brakes.
• Keep a safe distance according
to road conditions and vehicle
speed. If the vehicle to vehicle
distance is too close during a
high-speed driving, it may cause
a serious collision.
• The smart cruise control system
can not recognize a stopped
vehicle, pedestrians or an
oncoming vehicle. Always look
ahead cautiously to prevent
unexpected and sudden situa-
tions from occurring.
• In front of you, vehicles moving
with a frequent lane change may
cause a delay in the system's
reaction or may cause the system
to react to a vehicle actually in an
adjacent lane. Always look ahead
cautiously to prevent unexpected
and sudden situations from
occurring.
(Continued)
CAUTION
The smart cruise control system
may not operate temporarily due to
electrical interference.

VSM detects the distance from the vehi-
cle ahead with the sensor, to warn you
before collision and protect you in certain
hazardous situations.• If the VSM senses the object ahead too
near the vehicle and if driver's operat-
ing of the brake pedal or the steering
wheel should be needed, the warning
light illuminates.
Immediately reduce your speed.
• If the VSM senses more dangerous,
the warning sound also operates and
the accelerator pedal/seat belt
vibrates. Immediately reduce your
speed.
VEHICLE STABILITY MANAGEMENT (VSM) (IF EQUIPPED)
CAUTION
Always check the road conditions
to prevent danger even if the warn-
ing light does not illuminate, the
warning sound does not operate or
the accelerator pedal/seat belt does
not vibrate.

Malfunction indicator
• The VSM OFF indicator will illuminate
when the engine start/stop button is
turned ON, but should go off after
approximately 3 seconds. If the indica-
tor does not come on, or continuously
remains on after coming on for about 3
seconds when you turn the engine
start/stop button to the ON position, or
if the indicator comes on while driving,
the VSM is not working properly. Take
your vehicle to an authorized
HYUNDAI dealer and have the system
checked.
• The VSM OFF indicator may illuminate
when the ESP indicator or SCC indica-
tor comes on, but it does not indicate
malfunction of the VSM.
OVI059067
WARNING
The VSM is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility of the driver to always check
the speed and the distance to the
vehicle ahead.
WARNING
• Even if there is a malfunction to
the brake operating of the VSM,
when you depress the brake
pedal, the brake is operating nor-
mally. But, the VSM brake operat-
ing does not operate even in cer-
tain hazardous situations.
• The VSM is designed to function
above approximately 15 km/h (9.3
mph) and below approximately
180 km/h (111.8 mph).
• The VSM does not react to
- Persons or animals.
- Oncoming vehicles in the oppo-
site lane or the vehicle in the
intersection.
- Stopped objects.
• The VSM can not detect the
objects certainly, when:
- The sensors are stained with
dirt or covered.
- There is heavy rain or heavy
snow.
- There is interference by electro-
magnetic waves.
