OVERVIEW
The Terrai n Res pons e™ sys tem all ows the driver t o s el ect a program which aims t o provide t he opti mum set ti ngs fort racti on and performance for t he prevai li ng terrai n condit ions . The s ys t em cannot be swi tched off. 'Speci al Programs off' ist he default program and covers all general drivi ng condit ions . Three s peci fi c terrain programs are s electable to cover allt errai n s urfaces .
The s ys t em i s cont rol led by a rot ary control l ocat ed on t he cent er cons ol e, forward of t he transmis s ion s elector lever. Therot ary control al lows t he s electi on of one of the followi ng 4 programs :
Speci al programs offGras s /Gravel /SnowMud/Rut sSand.
The rot ary control can be rot at ed t hrough 360 degrees or more in ei ther direct ion and s elects each program i n t urn. W henTerrai n Res pons e i s fi tt ed t o a vehicle, a hi -l ine i nst rument clus t er wi ll als o be fi tt ed which wi ll dis play t he s electedprogram in the mess age cent er.
The Terrai n Res pons e s ys tem uses a combi nat ion of a number of vehicle s ub-s ys tems to achieve t he required vehi cl echaract eri st ics for the t errain s elected. The fol lowi ng s ub-s ys t ems are us ed i n t he Terrai n Res pons e s yst em:

The rot ary control swi tch pack als o contai ns the Terrain Res ponse cont rol module. The cont rol module det ect s t he s el ect ionmade on t he rot ary cont rol and transmit s a s ignal on the hi gh s peed Cont rol ler Area Net work (CAN) bus which i s receivedby each of the s ub-s ys tem cont rol modules . Each of t he affect ed cont rol modules contai n s oft ware whi ch appl ies t hecorrect operati ng paramet ers t o t hei r cont rol led s yst em for the Terrai n Respons e program s electi on made. They als oprovide feedback for t he s elected program s o that the Terrai n Respons e cont rol module can check that all s yst ems havechanged t o t he correct operati ng paramet ers .

TERRAIN RESPONSE ROTARY CONTROL AND MODULE
ItemPart NumberDescription1-Hil l Des cent Cont rol (HDC) s wi tch
2-Special programs off
3-Gras s /Gravel/Snow program4-Rot ary cont rol
5-Mud/rut s program
6-Sand program7-Dynami c Stabil it y Control (DSC) s wit ch
Each program is denoted by a s ymbol whi ch repres ent s t he t errai n encountered. The rotary cont rol wi ll only s elect the las tprogram in it s direct ion of rotat ion. Further rot ati on of the control in ei ther direct ion, once the l ast program has beens elect ed, wil l have no effect, for exampl e; once 'Sand' has been s elect ed, furt her rotat ion i n a clockwis e direct ion wil lret ain 'Sand'.
The cont rol module and rot ary cont rol i s connected vi a a harnes s connector which al so cont ains t he wiring for the HDC andDSC s wit ches and the i ll uminati on circuit s . The cont rol module and rotary cont rol uses 4 of t hes e wi res for 12V bat t erys uppl y (i gnit ion - only when the i gni ti on is on) a ground and high s peed CAN bus (pos i ti ve and negat ive).
PRINCIPLES OF OPERATION
The fol lowing vehicl e s ub-s ys t em control modul es are us ed for t he Terrain Res pons e sys tem:
Engi ne management - Engine Cont rol Module (ECM)Trans mis s ion control - Transmis s ion Control Modul e (TCM) (automat ic t rans mi ss ion only)Acti ve on-demand coupli ng cont rol moduleBrake s ys tem - Anti -l ock Brake Sys t em (ABS)/Dynami c Stabil it y Control (DSC)/Electroni c Tracti on Control (ETC)/ Hi llDes cent Control (HDC) - ABS module

Each sub-sys tem operates in di fferent ways in relati on t o t he sel ect ed Terrai n Res pons e program t o achieve t he opt imumt racti on, s t abi lit y and eas e of cont rol for t he t errai n encount ered.
Engine Management System (EMS)
The EMS can change t he accel erator pedal maps to change the amount of t orque per percent age of pedal travel .
Each terrain program uses a combi nat ion of operat ing paramet ers for each sub-sys tem. Changing bet ween terrain programsini ti at es a di fferent s et of operat ing characteris ti cs which wil l be noti ceable to the driver, for example; i f the accel erat orpedal i s held i n a const ant pos i ti on and the terrain program is changed from Gras s /Gravel /Snow t o Sand, the driver wil lnoti ce the t orque and engine s peed increas e. If t he t errai n program is changed from Sand t o Grass /Gravel/Snow, t he dri verwil l not ice a reduct ion in t orque and engine s peed.
• NOTE: The change i n t orque and engine s peed can take approximat ely 30 s econds and care mus t be taken not to confus et he Terrai n Respons e s yst em operat ion wit h an EMS faul t.
Transmission Control (Automatic transmission only)
The t ransmis s ion control modul e changes t he shi ft maps for the Terrain Respons e program s elect ed. Thi s changes t he s hi ftpoints providing early or l at e ups hift s and downs hi ft s .
For example, i n t he Gras s /Gravel /Snow program, the trans mi ss i on wil l perform early ups hi ft s and very late downs hifts toensure t he transmis si on is in t he highes t gear pos si ble. The hil l det ect ion funct ion of t he Trans mis s ion Cont rol module(TCM) will l ock t he t orque converter and hold whi chever gear i s s el ect ed t o t he engine s peed (RPM) li mit i f neces s ary whendescending a s t eep incli ne. This provi des maximum engi ne braking before t he dri ver needs t o appl y t he brakes.
Sport mode i s only avail abl e when t he general program i s s elected. Sport mode i s disabled i n all Terrain Res pons e s peci alprograms. 'CommandShift ™' is avail abl e in any program.
Active On-Demand Coup ling Control
The act ive on-demand coupli ng cont rol module has 2 operati ng s trat egies ; pre-empt ive and react ive.
The pre-empti ve st rat egy anti ci pat es and predict s the locki ng torque val ue required t o mi ni mi ze sl ip and maxi mizes tabil it y. Each Terrain Res pons e program has a different t hres hol d and i nput cri teria for the pre-empt ive s t rategy. Forexampl e, a higher locki ng t orque would be appl ied on s li ppery s urfaces .
The reacti ve s trategy vari es the amount of locking t orque in res pons e t o t he actual s lip level and t he dynamic behavi or oft he vehi cl e. Each Terrain Res pons e program has a different t hres hol d and input for the react ive s trategy. The reacti ves trategy i mproves vehi cl e t racti on and compos ure by eliminati ng any wheel s pin which has occurred aft er the pre-empt ives trategy was appli ed. The l ocking res pons e appli ed is appli cable to the t errain program sel ect ed. For exampl e, verys ens i ti ve on s lippery surfaces to provide maximum t racti on and mi nimi ze surface damage.
The locking t orque calculati ons use various s ignals from other s ub-s yst ems , for example, engi ne torque, accel erator pedalposi ti on, s elect ed gear, st eeri ng angl e, vehicle s peed, lat eral accelerat ion, yaw behavi or.
The DSC funct ion of t he ABS s ys t em can override t he act ive on-demand coupli ng cont rol and reduce any appl ied l ocki ngt orque during DSC act ion.
ABS System Control
The ABS module cont rols several functi ons and adjust s t he operati ng paramet ers of t hes e funct ions t o opti mize thes elect ed Terrain Res pons e program.
Tracti on Control
Tracti on cont rol us es different s li p/accel erati on thresholds to i mprove t ract ion and vehicle compos ure. For example, t hes ys t em s ens it ivit y is increased on s lippery surfaces s uch as wet grass or s now t o reduce wheel s pi n. If wheel s pi n wasall owed in t hese ci rcums tances, l oss of t ract ion may res ul t from surface damage (wet grass ) or t he car being unable tomove (snow) due t o wheel spi n.
Dynamic St abi li ty Cont rol
If DSC is s wi tched off (wit h t he DSC s wi tch adjacent to t he Terrain Res pons e rotary cont rol ) when usi ng a TerrainRespons e s peci al program, if t he s peci al program i s s ubs equent ly changed for a di fferent program, DSC is aut omat icall ys wit ched back on.
The DSC us es different t hres hol d values for t he s elected program t o aut omati call y reduce DSC i ntervent ion, removing t herequirement for t he dri ver t o dis able t he DSC s ys tem in order to reduce engine intervent ion whi ch is s omet imes i nduced i nextreme off-road condi ti ons . In ext reme s and condit ions , there may be an addit ional benefit of dis abling the DSC funct ionus ing t he DSC s wit ch in addi ti on to sel ect ing t he s and program.
In the Mud/Ruts program the DSC sys tem is cal ibrat ed t o tol erate a higher 'yaw' thres hold. This al lows a greaterdifferent ial between t he actual and des i red wheel turni ng behavi or before DSC i ntervenes . Thi s all ows the DSC s ys t em t oignore the effect of rut s 'jarring' t he car or adjust ing t he front wheel s t eering angle.
The Terrai n Res pons e s ys tem can al ter t he balance bet ween engine and brake i ntervention. For example, when t he s andprogram is sel ect ed, t he DSC s ys tem reduces it s rel iance on engi ne int erventi on and increas es the us e of brakeint erventi on to maint ai n t he vehi cl es momentum and prevent it from becomi ng bogged down i f wheel s li p i s detected.
Hil l Descent Cont rol
HDC i s automat icall y s wit ched on or off and target s peeds are adjus t ed in res pons e to t he Terrai n Res pons e programs elect ed. The res pons iveness of the HDC functi on is al so increas ed where requi red.
