STEERING 
COLUMN LOCKED Red warning triangle 
illuminated in LCD. Fault has occurred preventing the 
steering column lock from unlocking. This will also prevent the engine from 
starting. Press the stop/start button to return to 
accessory mode 4. If steering column  
is still locked, investigate cause of 
fault and interrogate the CJB (central junction box) for faults and diagnose 
using an approved Jaguar Diagnostic System. IGNITION ON 
Red warning triangle 
illuminated in LCD. Stop/start button has been pressed 
without the brake pedal depressed. Ignition is now in power mode 6. None ENGINE STOP 
BUTTON PRESSED Red warning triangle 
illuminated in LCD. Engine stop button has been pressed 
when the vehicle is moving. Engine will 
not be switched off until button is pressed quickly for a second time. Do not stop engine when vehicle is 
moving unless necessary. LIGHTS ON 
Amber warning triangle 
illuminated in LCD. Side lamps or headlamps are on and the 
driver's door has been opened. Switch off headlamps to avoid 
excessive drain on battery. AUTOLAMP 
DELAY OFF None 
Autolamp delay feature has been 
deactivated by moving light control 
switch from the auto position. None AUTOLAMP 
DELAY XX:XX None 
Lighting control switch has been moved 
to one of the 4 autolamp delay 
positions. Message displays delay timer period selected. None AUTOLAMP 
DELAY None 
Autolamp delay is selected on the light 
control switch and the driver has 
switched off ignition and opened driver's 
door initiating the autolamp delay. None. Message will extinguish once the 
selected delay timer has switched off 
the headlamps. TAIL LAMP 
FAILURE None The tail lamp LED (light emitting 
diode)'s are not functioning correctly. 
Location shown on vehicle image. Correct fault in rear lamp assembly, 
RJB (rear junction box) or wiring. BRAKE LAMP 
FAILURE None The brake lamp LED's are not functioning correctly. Location shown on displayed vehicle image. Correct fault in rear lamp assembly, 
RJB or wiring.   INDICATOR LAMP 
FAILURE None 
A turn signal indicator bulb  has failed. 
Location is shown on displayed vehicle image. Replace failed turn signal indicator 
bulb. E-DIFF NOT 
AVAILABLE Amber warning triangle 
illuminated in LCD accompanied with a single 
chime Differential temperature has reached the 
overheat threshold. System deactivated 
until temperature returns within limits. Allow differential to cool. E-DIFF FAULT 
Amber warning triangle 
illuminated in LCD accompanied with a single 
chime Fault has occurred with electronic 
differential. System deactivated until 
fault rectified. Investigate cause of fault and 
interrogate the system for faults and 
diagnose using an approved Jaguar Diagnostic System. ENGINE OIL LOW 
Amber warning triangle 
illuminated in LCD accompanied with a single 
chime The oil is at the minimum level for safe 
operation. Top-up with 1 liter (1.8 pints) of oil. ENGINE OIL 
HIGH Amber warning triangle 
illuminated in LCD accompanied with a single 
chime This warning is displayed when the 
engine is started, if the oil is above the 
maximum level for safe operation. Stop the vehicle as soon as safety 
permits and have the engine oil 
drained to correct level, before driving 
the vehicle. ENGINE OIL 
CRITICALLY LOW Red warning triangle 
illuminated LCD accompanied with a single 
chime The oil is below the minimum level for 
safe operation. Stop the vehicle as soon as safety 
permits and top-up with 1.5 liters (2.6 
pints) of oil. Wait for 10 minutes, 
re-check the oil level reading and top-up again if necessary. ENGINE OIL 
LEVEL MONITOR 
SYSTEM FAULT Amber warning triangle 
illuminated in LCD accompanied with a single 
chime A fault with the oil level monitoring 
system is indicated. Investigate cause of fault and 
interrogate the ECM for faults and diagnose using an approved Jaguar Diagnostic System. WATER IN FUEL 
Amber warning triangle 
illuminated in LCD accompanied with a single 
chime The water in fuel sensor in the fuel filter 
has detected water in the fuel system. Drain fuel filter to remove collected 
water. Odometer Display 
 
The odometer displays the total distance which the vehicle has traveled. This is calculated by the instrument cluster using 
wheel speed signals from the ABS module.  
The odometer can show 6 characters and distances up to 999,999 miles or kilometers. The total distance travelled is stored in a 
EEPROM (electrically erasable programmable read only memory) and the RAM (random access memory). This ensures that the 
total distance is not lost if the battery is disconnected. 
 
The odometer value is passed to other vehicle system modules on the medium speed and high speed CAN bus. This is used to record the total vehicle mileage for diagnostic purposes and when storing DTC (diagnostic trouble code)'s.
