The turn signal indicator, side and stop lamps and reverse lamps are located in each outer rear lamp assembly. The side lamps
and stop lamps use 24 LED's. The 24 LED's are illuminated at a higher intensity than the side lamp when the stop lamp switch is operated by pressing the brake pedal. A side marker lamp is fitted to the outer rear lamp assembly and is fitted in all
markets. The side marker lamp also uses 4 LED's and are active at all times when the side lamps are selected on.
The stop lamps can also be activated by the adaptive speed control system. A signal from the adaptive speed control module
is sent via the high speed CAN bus to the RJB which activates the stop lamps until an off message is received. Turn Signal Indicator

The turn signal indicator lamp uses a Phillips Hypervision glass filament bulb. The bulb is located in a holder which has
contacts which mate with contacts on lamp body. The holder locates in the lamp body and is rotated to lock.

If a bulb fails, the remaining turn signal indicator lamps continue to flash at the normal speed. The applicable turn signal
indicator in the instrument cluster will flash at double speed to indicate the bulb failure to the driver. www.JagDocs.com

Rear Fog Lamp

The rear fog lamps are located in separate units attached to the luggage compartment lid. The rear fog lamps each use 3 high
intensity LED's. The fog lamp locates in a recess in the luggage compartment lid has a seal to prevent the ingress of water into the luggage compartment. The lamp is secured in the recess with a metal securing clip. The rear fog lamp is activated
using a button located on the auxiliary lighting switch in the instrument panel.

LICENCE PLATE LAMPS

Two licence plate lamps are located in the luggage compartment lid trim finisher. One is located adjacent to the emergency
luggage compartment lid release key barrel cover and the other is adjacent to the rear view camera (if fitted). The licence plate
lamps are active at all times when the side lamps are operating. Each lamp can be removed from the finisher by inserting a
wide, flat screwdriver blade or similar tool in a slot between the lamp lens and the finisher and gently levering the lamp from
the surround. The bulb is a push fit in a holder which in turn is a press fit in the lamp housing.

HIGH MOUNTED STOP LAMP

The high mounted stop lamp is located at the bottom of the rear windshield. The lamp is secured to a bezel in the parcel shelf
with 2 screws.

The high mounted stop lamp uses 12, red colored LED's which illuminate through a clear lens. The high mounted stop lamp functionality is the same as that described for the stop lamps.

TURN SIGNAL INDICATOR SIDE REPEATER LAMPS

The turn signal indicator side repeaters are located in each door mirror. On vehicles from 10MY the lamp is an LED unit which illuminates in an orange color. The LED unit is secured to the mirror bezel with 2 screws and is connected to the mirror wiring harness with a 2 pin connector.

The side repeaters have the same functionality and operate in conjunction with the front and rear turn signal indicators and
the hazard warning flashers.

HAZARD FLASHERS

The hazard flashers are activated by a non-latching switch located in the switch pack located in the center of the instrument
panel. The hazard flashers operate at all times when selected and operate independent of the ignition mode.

When the hazard flashers are selected on by the driver, a ground path is momentarily completed to the CJB which activates the front and rear and side repeater turn signal indicators. A second press of the switch is sensed by the CJB and the hazard flasher are deactivated. When the hazard flashers are active, they override any request for turn signal indicator operation.
The hazard flashers can also be activated by a crash signal from the RCM. Refer to: Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) (501-20B Supplemental Restraint System, Description and Operation).
