2. CAUTIONS
Note that the display does not show everything in the rear area. Always check nobody,
especially animals and children, is behind the vehicle when parking or reversing.
If you can not properly check the vehicle behind, get out of the vehicle and then visually
check it.
The parking aid system is just a supplemental device to help your parking.
Always keep the safety precautions.
Do not press or shock the sensors by hitting or using a high-pressure water gun while
washing, since it may damage the sensors.
If the system is in normal operating condition, a short beep sounds when the shift lever is
moved into "R" position with the ignition key "ON". -
-
-
-
-
-
The parking aid system will not work or improperly work under following cases: ▶
1. Certain obstacles that sensors can not detect
Thin and narrow objects, such as wires, ropes, chains
Cotton, sponge, clothes, snow; that absorb ultrasonic waves
Obstacles lower than the bumper (ex. drain ditch or mud puddle) -
-
-
2. Not defective but improperly working
When the sensing portion is frozen (operates normally after thawed)
When the sensing portion is covered by rain, water drops, snow or mud (operates normally
after cleaned)
When receiving other ultrasonic signals (metal sound or air braking noises from heavy
commercial vehicles)
When a high-power radio is turned on -

1. OVERVIEW
The propeller shaft transfers the power through the transmission and transfer case to the front/rear
axle differential carrier (final reduction gear).
It is manufactured by a thin rounded steel pipe to have the strong resisting force against the torsion
and bending.
Both ends of propeller shaft are connected to the spider and the center of propeller shaft is
connected to the spline to accommodate the changes of the height and length.
The rubber bushing that covers the intermediate bearing keeps the balance of rear propeller shaft
and absorbs its vibration.
Function of propeller shaft ▶
Transmits driving torque.
Compensates the angle change (universal joint / CV joint).
Compensates the axial length change (splines for the slip joint). -

2. FRONT SUSPENSION (DOUBLE WISHBONE)
Advantage ▶
The advantage of a double wishbone suspension is that it is fairly easy to work out the effect
of moving each joint, so the kinematics of the suspension can be tuned easily and wheel
motion can be optimized.
It is also easy to work out the loads that different parts will be subjected to which allows more
optimized lightweight parts to be designed.
They also provide increasing negative camber gain all the way to full jounce travel unlike the
MacPherson strut which provides negative camber gain only at the beginning of jounce travel
and then reverses into positive camber gain at high jounce amounts. 1.
2.
3.
Disadvantage ▶
The disadvantage is that it is slightly more complex than other systems like a MacPherson strut.
Due to the increased number of components within the suspension setup it takes much longer to
service and is heavier than an equivalent MacPherson design. 1.
2. Double wishbone suspension is an independent suspension design using two (occasionally parallel)
wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the
chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to
control vertical movement. Double wishbone designs allow the engineer to carefully control the
motion of the wheel throughout suspension travel, controlling such parameters as camber angle,
caster angle, toe pattern, roll center height, scrub radius, scuff and more.

3) Caster
The angle between the vertical line and king pin, which fixes the steering knuckle and front axle,
(steering column which connects the top and bottom ball joints in the independent axle type)
when viewed the tires from the side.
Caster: With considering the height difference between the wheel centers of the front and rear
wheels. (Under standard condition that the vehicle is on a level ground) ▶
Positive caster: Top of the king pin is tilted backward from the vertical line of the wheel center
when viewed the tires from the side ▶
Advantages:Directional force to go straight (following control)
Restoring force of the wheel (restored to the straight ahead direction)
Prevention of wheel shimmy (wheels wobble left and right) -

Negative caster: Top of the king pin is tilted forward from the vertical line of the wheel center
when viewed the tires from the side ▶

Disadvantages:Impact from the road is transferred to the steering wheel (steering wheel
turns)

Check the pedal height with below
procedures: -
Start the engine and measure the length
(A) between floor mat and pedal.
If the measured value is out of the
specified value, adjust the length. 1.
2.
Adjust the pedal height with below
procedures: -
Disconnect the stop lamp switch connector.
Unscrew the lock nut and remove the stop
lamp switch assembly.
Loosen the lock nut on the pedal push rod.
Turn the pedal push rod to adjust the pedal
height.
Tighten the lock nut.
Install the stop lamp switch assembly.
Connect the stop lamp switch connector.
Check if the stop lamps come on when
pressing the brake pedal around 5 mm.
If the stop lamp dpes not come on, adjust
the stop lamp switch assembly again.
If the stop lamps come on, tighten the lock
nut and measure the pedal height again. 1.

Let the engine run for 1 to 2 minutes and
stop it. If the brake pedal stroke is
shortened as pumping the brake pedal,
the system is normal. If not, the system is
defective.
Depress the brake pedal several times
with engine off. If the brake goes down
when starting engine with pedal
depressed, the system is normal. If not,
the system is defective.
Depress the brake pedal when the engine
is running. If the pedal height is not
changed for 30 seconds after stopping
the engine, the system is normal. If not,
the system is defective. 1.

If the above three checks are OK, the system
is normal. If any condition is not met, check
the valve, vacuum hose and brake booster. Brake Booster ▶
