the RCM and illuminated by the instrument cluster on receipt of high speed CAN bus messages. The safety belt warning indicator is not subject to the 3 second indicator check when the ignition is switched on.
The operation of the passenger seat buckle switch is as described below with the exception that the instrument cluster must
receive a hardwired signal from the belt minder control module to indicate that a passenger is occupying the seat.
The safety belt warning indicator is subject to a timer. The warning indicator is activated when the following conditions exist:
Ignition is switched on
One of the front seat belts is unbuckled
USA market only - 75 seconds has elapsed after ignition on mode is selected
Vehicle is not in reverse gear
Vehicle speed is more than 8 km/h (5 mph).
Once the above parameters are met, the instrument cluster flashes the warning indicator at 2 Hz for 10 seconds accompanied
by a simultaneous chime. After 10 seconds the chime ceases and the warning indicator is permanently illuminated for 20
seconds. This sequence is repeated every 30 seconds until one of the following events occurs:
300 seconds has elapsed
The safety belt of the occupied front seats is fastened
The ignition is switched to off mode
The vehicle speed decreases to below 5 km/h (3 mph).
NOTE: On USA market vehicles, the warning indicator in not permanently illuminated.
The safety belt minder function cannot be disabled. The seat belt minder function can be disabled.
Refer to: Safety Belt System (501-20A Safety Belt System, Description and Operation). 14. Side Lamp Indicator
The instrument cluster controls the green colored side lamp indicator on receipt of a side lamp status message on the medium
speed CAN bus from the CJB and the auxiliary junction box. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. Selections using this switch are detected by the cluster which requests the side or
headlamp operation via a message to the CJB and the RJB. The CJB and the RJB responds with a side lamp active message and the cluster illuminates the side lamp indicator. The side lamp indicator is not subject to the 3 second indicator check when
the ignition is switched on.
15. High Beam Indicator
The instrument cluster controls the blue colored high beam indicator on receipt of a high beam status message on the medium
speed CAN bus from the CJB. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. High beam or flash selections using this switch are detected by the cluster which requests the light
operation via a CAN message to the CJB. The CJB responds with a high beam active message and the cluster illuminates the high beam indicator. The high beam indicator is not subject to the 3 second indicator check when the ignition is switched on.
16. Rear Fog Lamp Indicator
The amber colored rear fog lamp indicator is controlled by the auxiliary junction box and illuminated by the instrument cluster
on receipt of a rear fog lamp on message on the medium speed CAN bus from the RJB. The indicator is illuminated for as long as the rear fog lamps are active. The rear fog lamp indicator is not subject to the 3 second indicator check when the ignition is
switched on.
SPEEDOMETER
The speedometer is driven by high speed CAN signals transmitted by the ABS module. The wheel speeds are measured by sensors reading the rotational speed of the rear wheels from toothed targets on the hubs. An average of the two wheel speeds
are passed from the sensors to the ABS module in the form of pulsed signals. The ABS module converts these signals into a speed output on the high speed CAN to the instrument cluster. The same speed outputs from the wheel speed sensors are also used to calculate the distance the vehicle has travelled.
TACHOMETER
The tachometer is driven by an engine speed signal transmitted on the high speed CAN from the ECM. The signal is derived from the CKP (crankshaft position) sensor. The signal is received by the instrument cluster microprocessor and the output from
the microprocessor drives the tachometer.
FUEL GAGE
The fuel gage is controlled by CAN messages from the RJB. The RJB reads the values output by the fuel level sensors every 131 ms and transmits a fuel tank contents value, corrected for battery voltage, in a CAN message to the instrument cluster. A fuel pump symbol is displayed to the left of the linear gage. An arrow above the symbol shows the driver on which side of the
vehicle the fuel filler cap is located. Above the linear fuel gage, is a LCD (liquid crystal display) area which displays odometer
and trip readouts. When a trip computer function is selected, these are replaced by a trip computer display for the trip function
selected.
LIQUID CRYSTAL DISPLAY
In the area above and below the message center is a LCD display. The area below the message center displays a linear fuel www.JagDocs.com

Battery and Charging System - General Information - Battery Care
Requirements
Description and Operation
1. INTRODUCTION
This document defines the requirements for care and maintenance of batteries, and the standard of battery care at dealers and
retailers for new vehicles.
This applies to all types of 12 Volt Lead Acid Batteries used in Jaguar and Land Rover vehicles whether they are conventional
flooded technology or Absorbed Glass Mat (AGM – also known as Valve Regulated Lead Acid (VRLA)) technology and also
applies to both Primary, Secondary and Auxiliary Batteries. AGM batteries offer improved resistance to cycling as seen in stop
start applications.
In order to prevent damage to the battery and ensure a satisfactory service life, all processes detailed within this document
must be rigorously adhered to.
It is equally important therefore to note the following key points:
All new vehicles leave the factory with either a transit relay installed and/or have a transit mode programmed into the
vehicle control modules. The transit relay must be removed and the transit mode disabled (where applicable) using an
approved diagnostic system, NOT MORE THAN 72 HOURS before the customer takes delivery.
The battery can be discharged by the following mechanisms:
- Self Discharge: - A lead acid battery will very slowly discharge itself due to its own internal chemical processes
whether it is connected to a vehicle or not.
- Quiescent Discharge: - The vehicle electrical systems when connected to the battery will draw charge from the
battery.
12 Volt Lead Acid Batteries rely on internal chemical processes to create a voltage and deliver current. These processes and
the internal chemical structure of the battery can be damaged if the battery is allowed to discharge over a number of weeks /
months, or is left in a discharged state for a lengthy time period.
On vehicles with conventional ignition keys, these must not be left in the ignition lock barrel when the transit relay
has been removed, otherwise quiescent current will increase and the battery will discharge more rapidly.
For keyless vehicles, the Smart Key must be stored at least 5m (16 ft) away from the vehicle when the vehicle is
parked or stored.
AGM Batteries are fully sealed and cannot have the electrolyte level topped up.
NOTE: Dealers and retailers involved in the storage / handling of vehicles and replacement batteries have a responsibility
to ensure that only a fully charged battery may be processed through the distribution selling chain.
2. GENERAL RULES FOR BATTERY CARE
2.1 Dealer Demonstration Vehicles
Vehicles used as dealer demonstrator(s), in a showroom, must be connected to a JLR approved showroom conditioner capable
of delivering 50 Amps. This will prevent the battery from being damaged.
2.2 Software Reflash, SDD work or Ignition On related workshop activities
Due to the high electrical current demand and high depth of discharge that can occur during vehicle software re-flash activities,
SDD work or ignition on (power mode 6) related work in the workshop, vehicles that are undergoing such activities MUST have a
JLR approved power supply capable of delivering 50 Amps or more.
2.3 Extended Vehicle Rework
For any extended vehicle rework that results in consuming vehicle power, either the battery should be disconnected or a JLR
approved power supply connected.
2.4 Jump Starting New vehicles before they have been delivered to the customer
It is the dealer / retailers responsibility to make sure the battery is not allowed to discharge by following the
instructions and processes defined in this manual.
However, if circumstances dictate that a new vehicle must be jump started due to a discharged battery whilst the
vehicle is in the dealer / retailers care, the battery on this vehicle must be replaced with a new one prior to delivery
to the customer at the dealer / retailers liability.
The vehicle should also undergo investigation as to why the battery became discharged.
Do not connect the jump starting cable to the negative (-) terminal of the battery. Always connect to the recommended
earth point. As defined in the owners handbook or service documentation for that vehicle. 2.5 AGM Batteries
AGM batteries must not be charged above 14.8 Volts. Doing so will damage them.
AGM Batteries must be tested with a capable battery tester as detailed in the Equipment section (Section 5) of this
