3) Cautions on parking aid system
Note that the display does not show everything in the rear area.
Always check nobody, especially animals and children, is behind the vehicle.
Normal precautions when reversing should be maintained. *
*
The parking aid system is just a supplemental device to help your parking operation.
Always keep the safety precautions.
Do not press or shock the sensors by hitting or high-pressure water gun while washing, o
r
the sensors will be damaged.
If the system is in normal operating conditions, a short beep sounds when the gear selecto
r
lever is moved into “R” position with the ignition key “ON”.
If the system is in abnormal operating conditions, a beep sounds for 3 seconds when the
gear selector lever is moved into “R” position with the ignition key “ON” or engine
running. However, it is also occurred when the obstacle is within 50 cm from the rea
r
bumper. 1.

(1) The parking aid system will not work or improperly work under
following cases:
▶Certain obstacles that sensors can not detect
- Wires, ropes, chains.
- Cotton, sponge, clothes, snow that absorb ultrasonic waves.
- Obstacles lower than the bumper.
▶Not defective but improperly working
- When the sensing portion is frozen.
- When the sensing portion is covered by rain, water drops, snow or mud.
- When receiving other ultrasonic signals
(metal sound or air braking noises from heavy commercial vehicles).
- When a high-power radio is turned on.
▶Narrowed sensing area
- When the sensing portion is partially covered by snow or mud.

▶Not defective but may occur improper working
- When driving on the rough road, gravel road, hill and grass.
- When the bumper height is changed due to the heavy load.
- When the sensing portion is frozen.
- When the sensing portion is covered by rain, water drops, snow or mud.
- When receiving other ultrasonic signals
(metal sound or air braking noises from heavy commercial vehicles).
- When a high-power radio is turned on.
- When some accessories are attached in detecting ranges

TRANSFER CASE
This function is only available when the speed signal from speed sensor is about to stop
(below 2 km/h).
This function is only available when clutch pedal is depressed (manual transmission) o
r
selector lever is selected to “N” position (automatic transmission).
(TCCU must recognize the clutch pedal signal or “N” signal.)
Change the 4WD switch in instrument panel from 4H to 4L.
“4WD LOW” warning lamp in meter cluster blinks during this process, then remains
when the shift is completed.
“4WD CHECK” warning lamp comes on when the system is defective. -

TORQUE ON DEMAND
RODIUS 2006.09

2. GENERAL DESCRIPTION
TOD system means the full time 4WD system and the registered trade mark of Borg Warner.
TOD is an abbreviation of Torque On Demand.
TOD (Torque On Demand) system, which is superior than existing Full Time 4WD, checks the
road surface and vehicle conditions via various sensors and, subsequently, according to the
situations and conditions, distributes the most optimal driving force to front wheels and rea
r
wheels by activating the electro-magnetic clutch located inside of TOD Transfer Case.
TOD receives the speed signals from speed sensors installed in front axle and rear axle, the
TPS signals from engine, and the operating signals from ABS control unit via CAN.
Based on these data, TOD control unit controls the electro-magnetic clutch to distribute the
3:97 ~ 44:56 of driving force to front wheels and rear wheels.
The conventional system uses “FR driving” (theoretically, the 100 % of driving force is
transferred to rear wheels) on normal paved road.
When the system detects a slip in the rear wheels, a proper percentage of driving force is
transferred to front wheels.
TOD control unit receives the wheel speed signals from the speed sensors in propeller shaft o
f
transfer case and engine output information from the engine control unit.
TOD control unit changes the pressure force of the electromagnetic clutch based on the
analyzed data.
1) Distribution of Driving Force According to Road Surface
On normal road surface ▶
In vehicle with existing part time transfer case, when a driver turns the steering wheel to park in
the 4WD mode, the vehicle may halt sensation of tight corner braking phenomena. However, in
vehicle with TOD system, this phenomena does not occur and the driving force is properly and
automatically distributed.
On paved road with high speed ▶
Driving at high speed on roads such as highway mainly uses rear wheels as driving wheel.
At this moment, some of torques is also distributed to front wheels so that the vehicle could
maintain safe ground grab capacity against side winds and rain.
Distribution ratio: 15 % for front wheels and 85% for rear wheels.

2) Transfer Case
(1) Planetary gear set
Planetary Gear set consists of sun gear, ring gear and carrier. It is engaged with the gear in
“HIGH-LOW” collar to increase the driving force by reducing vehicle speed.
Sun gear is connected to input shaft and ring gear is fixed into the transfer case.
Splined rear output shaft is able to slide on the “HIGH - LOW” collar.
The inside and outside ends of “HIGH - LOW” collar have machined gear. The input
shaft transmits the power to driving wheels by engaging with sun gear and carrier gear.
If the 4WD switch is at “4WD HIGH”, the TOD control unit operates the shift motor to
engage “HIGH - LOW” collar directly with input shaft for transmitting the driving force
to front and rear propeller shafts.
When a driver selects “4WD LOW”, the TOD control unit controls the electro-magnetic
clutch and operates the shift motor to engage “HIGH - LOW” collar with carrier.
The power from transmission is increased up to 2.48:1 by reduction ratio from planetary
gear, and then is sent to front and rear propeller shafts. null
(2) Ball type slant cam and clutch
disc pack
If the speed sensors installed on front and
rear propeller shafts detect the slips at front
and rear wheels, and these slips exceed
the specified range, TOD control unit
controls electromagnetic clutch to transmit
driving force to front wheels.
At this time, ball slant cam is moved to
compress multi-disc located in clutch disc to
transmit driving force to front wheels.
