Safet y Precaut ions
The fol lowing safety precauti ons mus t be fol lowed when worki ng on t he xenon headlamp sys tem:
DO NOT att empt any procedures on t he xenon headlamps when t he li ghts are s wit ched onHandl ing of t he D1S Xenon bulb mus t be performed usi ng s uit abl e prot ect ive equipment, e.g. gloves and gogglesThe glas s part of t he bulb mus t not be t ouchedXenon bul bs mus t be dis posed of as hazardous was teOnly operat e t he lamp in a mounted condit ion i n t he reflect or.
W ARNING: T he Xenon system generates up to 28000 volts and contact w ith this voltage could lead to fatality.Make sure that the headlamps are sw itched off before w orking on the system.
Headl amp Cons truct ion and Funct ionali ty
The xenon lamp or Hi gh Int ens i ty Di s charge (HID) lamp as they are s ometi mes cal led, compris es an el li ps oidal lens wi th as olenoi d control led s hutt er to change t he beam output from low to hi gh beam.
• NOTE: If the l ight cont rol module rot ary s wit ch is in t he OFF pos it ion, the xenon lamps do not operat e when t he highbeam 'flas h' functi on is operat ed. If t he rot ary s wi tch i s in the headlamps pos it ion or AUTO pos it ion wi th the low beamlamps act ive, the xenon low beam wi ll remai n on when t he high beam 'flas h' funct ion i s operated.
The xenon headlamp sys t em i s cont roll ed by t he CJB usi ng a control modul e for each headl amp and an i gni ter. The cont rolmodules and t he ignit ers provide t he regulat ed power s upply requi red t o i ll uminate the xenon bulbs t hrough t hei r st art -upphas es of operat ion.
The xenon headlamp is a sel f cont ai ned unit located wit hi n t he headl amp as sembl y. The uni t compris es a refl ect or, t helens , a s hutt er controll er and t he xenon bul b, which as an as s embly i s known as the projector module.
The reflector provides t he mounti ng for t he xenon bul b which i s an i ntegral part of t he ignit er. The i gni ter l ocat es in anapert ure at t he rear of the refl ect or and is s ecured wi th 2 Torx s crews t o ens ure correct al ignment in the refl ect or.
A s hutt er is us ed t o change t he beam projecti on from l ow beam t o hi gh beam and vis a vers a. The s hut t er controller i s as olenoi d whi ch operat es t he s hut ter mechani s m vi a a l ever. W hen t he shut ter i s in the l ow beam pos it ion, it mas ks s omeof the light emi tt ed from the refl ect or, providi ng a defi ned low beam cut -off.
A t ouri st l ever mechani s m i s located on the right hand s ide of t he project or modul e. Thi s mechanis m moves a flap t o blankoff a porti on of the beam s pread to enabl e the vehicl e to be dri ven in opposi te dri ve hand markets wit hout applyingblanking decal s t o t he headlamp lens . The beam is changed by removing the cover at the rear of t he lamp ass embly andmoving a small lever locat ed at t he s ide of t he project or modul e.
The xenon bul b il lumi nat es when an arc of el ect ri cal current is es tabli s hed bet ween t wo electrodes wit hi n t he bulb. Thexenon gas s ealed i n t he bulb react s t o t he elect rical excit at ion and the heat generated by t he current flow to produce theblue/whi te li ght .
To operat e at ful l effi ci ency, the xenon bulb goes t hrough t hree s t ages of operat ion before ful l out put for cont inuousoperati on is achieved. The three phas es are; s t art -up phas e, warm-up phas e and continuous phas e.
In the st art -up phas e, the bul b requires an ini ti al hi gh vol tage s t art ing puls e of up t o 30000 volt s to est ablis h the arc. Thisis produced by t he i gni ters. The warm-up phas e begins once t he arc i s est abli shed. The xenon control modul es regulat et he supply to the bulbs t o 2.6A which gi ves a lamp out put of 75W . During t his phas e, the xenon gas begi ns to il luminat ebri ght ly and the environment wi thi n t he bul b s t abi lis es ens uring a cont inual current fl ow bet ween the el ect rodes. W hen thewarm-up phas e is compl et e, the xenon control modul es change t o cont inuous phas e. The s uppl y vol tage t o t he bulb i sreduced and the operat ing power requi red for conti nual operat ion i s reduced to 35W . The proces s from s tart-up t ocont inuous phas e i s complet ed in a very s hort t ime.
The xenon sys tem is cont roll ed by t he CJB, t he two xenon control modul es and the two ignit ers . The xenon controlmodules (one per headlamp) receive an operati ng vol tage from the CJB when the headlamps are s wit ched on. The modulesregulat e t he power s upply requi red t hrough t he phas es of s tart-up.
The ignit ers (one per headl amp) generat e t he ini ti al hi gh vol tage requi red t o es t ablis h t he arc. The ignit ers have i ntegralcoi ls whi ch generate hi gh vol tage pul ses requi red for s tart -up. Once t he xenon bul bs are operat ing, the ignit ers provi de aclos ed ci rcuit for regulat ed power s upply from the control modul es.
ADAPTIVE FRONT LIGHTING SYSTEM (AFS)

The s ys t em operat es by t he AFS cont rol module recei vi ng inputs from t he engine cont rol module for engine runni ng s ignal ,t he ABS module for st eeri ng angl e and vehi cle s peed and a reverse gear i nput from the trans mi ss i on.
The AFS cont rol module proces s es thes e s ignals and provi des an output t o the headlamp leveling motors to adjus t theheadl amp hori zont al ai m according t o vehicle speed and s teering angle.
• NOTE: In market s wit h Dayt ime Running Lamps (DRL), t he AFS s yst em will not operate when the DRL are act ive.
The AFS cont rol module is connect ed on the hi gh s peed CAN bus to receive i nformat ion from other vehicle s ys tems . Thecont rol module is connect ed to the AFS power module on a dedi cat ed Local Interconnect Net work (LIN) bus . The AFScont rol module cal culat es, us ing input dat a from other s ys t ems , the requi red pos it ion of t he hori zont al adjus t ment of t heproject or modul es. The pos it ion i nformat ion is t hen output on t he LIN bus to t he AFS power module l ocat ed on eachheadl amp as sembl y. Thi s module t hen outputs the appropriate s ignal s t o power the AFS s t epper mot ors i n t he headl ampt o the appropriat e posi ti on.
The hori zont al pos it ion of t he project or modul es is dependant on a number of input vari abl es . The pos it ion i s determinedby vehi cle s peed and s teeri ng angl e. W hen reverse gear i s elected, the projector modules are moved t o t he st rai ght aheadposi ti on t o avoi d glare t o other road us ers .
The angl es of each projector module di ffer to gi ve the correct spread of light , for example, when turning l eft , the l eft handproject or modul e wi ll have a great er s wi vel ling angl e than t he right hand projector module.
In the event of a fai lure of the AFS sys tem, a warning indicator in the ins trument cl us t er flas hes t o warn the driver. TheAFS warni ng indicator i lluminates when t he i gni ti on s wit ch is i n power mode 6 and will flas h cont inuousl y unti l the faul t isrect ifi ed.

The faultmay be caus ed by a fai lure of anot her sys tem s uch as st eeri ng angl e s ens or or the vehicle s peed s i gnal mi ss i ng,preventi ng the AFS s ys tem operati ng correctl y.
HEADLAMP LEVELING
Headl amp l evel ing provides for the adjus t ment of the vert ical aim of the headlamps to minimi ze glare to other road us erswhen t he vehi cl e att it ude changes due t o vehi cle l oadi ng.
Two t ypes of headlamp l evel ing are avai lable dependant on the t ype of headlamps fit ted to the vehicle:
Manual headlamp l evel ing - Hal ogen headlamps only (ROW vehicles only)Automat ic headlamp level ing - Xenon headlamps only.
Manual Headlamp Leveling - ROW Halogen Headlamps Only
Manual headlamp l evel li ng is only avai lable on RO W vehicles wit h halogen headl amps .
• NOTE: Headlamp l evel ling is not avai lable on NAS vehicles wi th hal ogen headlamps .
The manual s ys tem compris es t he fol lowing components :
