DIESEL MISFUELLING PROTECTION
DEVICE
Diesel engine vehicles in some markets are
equipped with a misfuelling protection device,
incorporated into the fuel filler neck, designed
to alert that the wrong fuel type has been
selected. If the narrow filler nozzle fitted to
pumps delivering unleaded petrol is correctly
inserted (i.e. fully inserted) into the filler neck,
the misfuel protection de vice will activate.
The protection device c ontinually interrupts the
fuel flow from the pump, until the protector
mechanism in the filler neck is reset.
When activated, the yellow protection device
will be visible in the f iller neck. The device will
need to be reset before the tank can be
correctly filled with dies el fuel. This is achieved
using the reset tool, lo cated in the luggage
compartment, clipped onto the battery
restraining bar.
Note: It is the driver’s responsibility to fill the
vehicle with the correct fuel. The diesel
misfuelling protection devi ce only reduces the
risk of filling the vehicle with the incorrect fuel.
Note: When refuelling the vehicle using a
disposable fuel canister, use a canister
designed for diesel fuel where possible. The
spout on petrol canist ers may activate the
protection device. The device may also be
activated by fuel pumps with a smaller nozzle
than those fitted to standard diesel pumps.
Resetting the protection device
To reset the misfuelling protection device:
1. Insert the reset tool (with the teeth
uppermost) into the fi ller neck opening, as
far as it will go. The triangular section on
the reset tool stop s on the protection
device at the requi red insertion depth.
2. Pivot the reset tool handle downwards to
engage the teeth into the protection device.
3. Keeping the reset tool handle held down,
slowly pull the reset tool out of the filler
neck to reset the misfuelling protection
device.
Note: To ensure that the pr otection device is
correctly reset, check that the yellow protector
is no longer visible in the filler neck.
After resetting the misfuelling protection
device, remove the tool fr om the filler neck and
secure it to the battery restraining bar. If
subsequent driveability difficulties are
encountered, seek assistance from your
Dealer/Authorised Repairer.
WARNINGS
When the misfuelling protection
device is activated, it could cause fuel
to be discharged from the filler neck.
CAUTIONS
Using the incorrect fuel can result in
major damage to your vehicle’s engine
and fuel system.

Vehicle battery

Your vehicle is fitted with a low maintenance
battery, which is located under the floor of the
luggage compartment.
In hot climates more frequent checks of the
battery electrolyte level and condition are
required. If necessary, the battery cells can be
topped up using di stilled water.
When the ignition is switched on, but without
the engine running, BATTERY NOT CHARGING
is displayed in the mess age centre. The battery
will only charge when the engine is running.
Note: Do not connect any 12 volt equipment
(e.g. a 12 volt inspection lamp), directly to the
battery terminals. Use the accessory socket
located in the cubby box, for connecting Jaguar
approved accessories.
Battery Monitoring System (BMS)
Your vehicle is equipped with a Battery
Monitoring System (BMS) which manages the
battery charging system and, if excessive
battery discharge is o ccurring when the engine
isn't running, shuts down non-essential
electrical systems to protect battery power.
In the event that too many electrical systems
are operational when the engine is not running,
and the battery charge is insufficient, the audio
and entertainment systems (if active) and
climate control system will be switched off.
This will be confirmed by a low battery warning
message displayed on the touch-screen. If this
occurs, switch on and run the engine for at
least five minutes, preferably with all auxiliary
electrical systems switched off (e.g. lights,
wipers, climate control, seat heaters etc.).
Note: The audio system can be operated
during this five minute period when the engine
is running.
If the engine is switched off before the five
minute period ends and the audio system is
switched on, the warning message will
re-appear on the touch-sc reen and the audio,
entertainment and climate control systems will
switch off again. For this reason, it is important
that the engine is left running for the full five
minute period.
Charging faults
If there is a fault in the battery charging system,
CHARGING FAULT is displayed with red
backlighting in the mess age centre. If this
occurs, switch off all non-essential electrical
systems and seek qualified assistance at the
earliest opportunity.
CAUTION
