3) General Instructions
Before lifting up the vehicle with a lift, correctly support the lifting points.
When using a jack, park the vehicle on a level ground and place the wheel chocks under the tires.
Position the jack under the frame and lift up the vehicle and then support with chassis stand before
service work.
Make sure to disconnect the negative (-) cable from the battery to prevent any damage to electric
systems.
If you have to work on vehicle, cover the seats and floor with protection covers to avoid any
damage and contamination.
Brake fluid and anti-freeze can damage the painted surface of body. So carefully handle them
during service work.
To improve the efficiency of service work, use only recommended and specified tools.
Use only Ssangyong genuine spare parts.
Never reuse the cotter pin, gasket, O-ring, oil seal, lock washer and self-locking nut. Replace them
with new ones. If reused, normal functions cannot be maintained.
Store the disassembled parts as a set based on disassembly order and unit.
Pay particular attention not to miss or mix the fasteners.
If necessary, especially for inspection, clean the removed parts completely.
Apply the oil or grease on the running and sliding surfeces before installation. Use the specified
sealant and gasket to prevent leakage if necessary.
Tighten the fasteners to the specified tightening torque.
As a final stage of service work, check if the serviced system is working properly and the problem
has been eliminated clearly. (1)

3) Cruise Control Switch
Cruise control switch
The cruise control is an automatic speed control system that maintains a desired driving speed without
using the accelerator pedal. The cruise control switch is fitted to the bottom right section of the steering
wheel. When this switch is operated, the AUTO CRUISE or ECO lamp on the instrument cluster comes
on.
The cruise control switch has a fivefold switch in it. The engine ECU can determine the current driving
condition since the resistance varies depending on the operation of the switch.
The cruise control system is operated at vehicle speed of between 38 km/h and 150 km/h. The manual
transmission is operated in the range of 3rd gear or higher.
This function can be used at the following traffic condition. (It is important to be careful for using this
function)
Cruise control (ON)
Cruise control (OFF)
Cruise control (Acceleration)Cruise control (Deceleration)
Cruise control (Reset)

1. OVERVIEW
Engine power reaches the transaxle via a torque converter with integral converter lock-up clutch. The six
forward gears and one reverse gear are obtained from a single planetary set, followed by a double
planetary set. This type of gear-set arrangement is commonly known as Lepelletier type gear-set.
The Model M11 6 speed automatic transaxle is electronically controlled. The control system is
comprised of the following components:
External transaxle control unit (TCU)
Internal embedded memory module (EMM)
Input and output speed sensors
Valve body unit comprised of four ON/OFF solenoid valves and six variable bleed solenoids (VBS)
Torque converter -
-
-
-
-
TCU controls the oil pressure for various internal clutches and bands to select the gear. It also controls
the electronic elements, shift pressure and torque converter slip. If the system is defective, TCU provides
FMEC (Failure Mode Effect Control) to maintain the functionality of transaxle. This keeps the basic
function of transaxle (gear selection) even when there are failure in controls and power supply.
There are selector shaft position sensor (inhibitor switch) and oil temperature sensor in transaxle. In
manual mode, TCU receives the information from TGS (Transmission Gear Selector) through PCB
(Printed Circuit Board) when driver selects the manual shift mode. TCU communicates with other
electric control modules through CAN. In order to ensure a safe driving state and to prevent damage to
the automatic transmission, TCU switches to Limp-Home mode in the event of critical faults.

3) Shift Map Selection
The driver can manually select between normal (S) and winter modes (W) via the mode switch.
Depending on the transaxle temperature, uphill and downhill grades and altitude, shift maps will be
selected by the TCU to suit the driving conditions. The following maps are available.
Standard (Normal) Mode ▶
Normal Mode is selected when the lever is in the D position with the mode switch in the normal (S)
position and the transaxle is within normal temperature ranges. Shift schedule points are optimised for
fuel efficiency and general driving conditions.
Uphill and Downhill Mode ▶
In this mode, depending on the load of the vehicle, adaptive shift maps are selected to progressively
adjust the shift points and torque converter lock points.
Altitude Mode ▶
Shift points are automatically adjusted at higher altitudes to compensate for changes in engine torque
where the torque produced by the engine is greatly reduced by the effects of reduced barometric
pressure and temperature.
Winter (W) Mode ▶
When winter mode is selected, starting in second gear is facilitated and the WINTER mode indicator
light is switched ON. To prevent wheel spin on slippery surfaces, the transmission will not allow first gear
unless manually overridden.
Warm up Schedule ▶

The torque converter will not lock-up below 20°C to assist in transaxle warm-up.
Hot Mode ▶

converter lock-up is increased to prevent heat generation by the torque converter.
Activation of the hot mode inhibits other transmission performance features including uphill and downhill
compensation and altitude compensation. Some degradation in shift feel may be experienced as the
torque converter is not unlocked during shifting.
Cruise Control Mode ▶
When cruise control is activated the engine ECU may request the transaxle to downshift under trailing
throttle conditions to increase engine braking.
Above 110℃the electrical radiator fans are switch ON
Above 130℃the engine torque will be reduced and the W light on the instrument cluster will flash
Above 200℃the transaxle will neutralise until the fluid tem
perature falls below 200°C as a final
protection.
