Towing
69
TowingTOWING A TRAILER
(V6 petrol and diesel vehicles only)
Never exceed the maximum weights
for the vehicle or the trailer. Damage
to the vehicle coul d occur and vehicle
stability and braking could be
adversely affected. This could lead to
loss of control and increased braking
distance, resulting in a rollover or
crash.
To preserve handling and stability,
only fit Jaguar approved towing
accessories.
Never use towing eyes or lashing
points to tow a trailer. They have not
been designed for this purpose and
doing so may cause them to fail,
resulting in injury or death.
When towing, do not exceed 100 km/h
(60 mph). If using a temporary spare
wheel, do not exceed 80 km/h (50
mph).
Note: It is the driver’s re sponsibility to ensure
that the towing vehicle, and the trailer, are
being used correctly and in accordance with
manufacturer’s reco mmendations and any
applicable legislation.
Information on towing, towing weight
capacities and regulati ons is available from
your Dealer and from the main motoring and
caravanning organisations.
The following are important points of safety,
stability and comfort. Seek further advice if
necessary.
• Maximum braked to wing weight is
permissible, provided that long periods of
uphill driving on gradients over 8% are not
undertaken. •
At altitudes above 1000 metres (3250 feet),
the stipulated maximum permitted Gross
Train Weight must be reduced by 10% for
every 1000 metres (3250 feet) in altitude,
because the thinner atmosphere can
reduce engine performance.
Diesel engines : When ambient temperature
exceeds 40°C (104°F), the engine coolant
temperature may increase above normal
operating level. If this occurs, the engine
management system will initiate a series of
actions to restore normal operating conditions,
which may include:
• A message centre message.
• Engine performance reduction.
• Air conditioning system cycling. The air
conditioning temper ature output will
fluctuate between hot and cold, in order to
dissipate engine heat. If engine overheat
persists, the air conditioning will move to
continuous heat output.
It is advisable to bring the vehicle and trailer to
a convenient stop and allo w the engine to idle
until normal temperature is restored. Do not
turn off the engine.
TRAILER ELECTRICAL CONNECTION
Only connect approved electrical
circuits, which are in good condition, to
the trailer socket. Connecting incorrect
or faulty circuits, may seriously damage
the vehicle’s electrical circuits.
The vehicle’s electrical system has been
designed to support all towing requirements
and comply with legal requirements for the
specific territory in which the vehicle is first
sold.
Note: The rear parking se nsors automatically
disable when the trailer electrical connection is
made using Jaguar approved towing
equipment.

Fuel and refuelling
152
Fuel and refuellingSAFETY PRECAUTIONS
Avoid exposing the f uel gasses to any
potential sources of ignition as the
resulting fire and explosion may
cause serious injuries and/or death.
Switch off the engine when refuelling,
as it is both a source of extreme
temperatures, and electrical sparks.
Switch off any personal electronic
devices such as mobile phones, or
music players.
PETROL ENGINED VEHICLES
Do not use leaded fuels, lead
substitutes or fuel additives.
Fuel system cleaning agents should not
be used, unless a pproved by Jaguar.
OCTANE RATING
The minimum octane rating for fuel used is 95
RON (Research Octane Number). The vehicle
will run on lower ratings, but it may cause
pronounced engine knock or pinking. If the
pinking is severe it ca n cause damage to the
engine, fuel and emis sion control systems.
Note: Occasional, light, engine knock
experienced while accele rating or climbing hills
is acceptable.
Super Green Plus 98 RON unleaded fuel (where
available) may be used as an alternative to the
standard 95 RON unleaded fuel.
Some countries have only 91 RON fuel
available. Vehicles sold in these countries are
specially calibrated to use this fuel.
ETHANOL
This vehicle is not suitable for use with
fuels containing more than 10%
ethanol.
Do not use E85 fuels (85% ethanol
content). Equipment necessary for the
use of fuels containing more than 10%
ethanol is not fitted to this vehicle. If
E85 fuels are used, serious engine and
fuel system damage will occur.
Fuels containing up to 10% ethanol (grain
alcohol) may be used. Ensure that the fuel has
octane ratings no lower than those
recommended for unleaded fuel. Most drivers
will not notice any opera ting difference with
fuel containing ethanol. If a difference is
detected, the use of co nventional unleaded fuel
should be resumed.
METHANOL
Wherever possible avoid using fuel
containing methanol.
Some fuels contain methanol (Methyl or wood
alcohol). If you use fuels containing methanol
the fuels must also contain co-solvents and
corrosion inhibitors fo r methanol. Also, do not
use fuels which contain more than 10%
methanol even if they contain co-solvents and
corrosion inhibitors. Fu el system damage or
vehicle performance pr oblems resulting from
the use of such fuels is not the responsibility of
Jaguar, and may not be covered under the
warranty.

Fuel and refuelling
155
To close the filler flap, push the flap until
latched closed.
Note: The filler flap will only be locked closed
when the vehicle is centrally locked.
FUEL FILLER
When refuelling ensure that all
windows, doors, and sunroof are fully
closed, particularly if young children
or animals are in the vehicle.
Do not attempt to fill the tank to its
maximum capacity. If the vehicle is to
be parked on a slope, in direct
sunlight or high am bient temperature,
expansion of the fuel could cause
spillage.
Check the fuel pump information
carefully, to ensure that you are putting
the correct fuel into the vehicle.
If the vehicle is filled with incorrect fuel,
it is essential that you seek qualified
assistance before you start the engine.
Fuel station pumps are equipped with
automatic cut-off sensing, to avoid fuel
spillage. Fill the tank until the filler nozzle
automatically cuts off the supply. Do not
attempt to fill the tank beyond this point.
Note: Filling station pumps used for diesel
commercial vehicles deliver fuel at a higher
rate than normal. The hi gher fill rate can cause
premature cut-off and ma y cause fuel spillage.
Therefore, it is recommended that only
standard light vehicle pumps are used.
DIESEL MISFUELLING PROTECTION
DEVICE
When the misfuelling device is
activated it may cause fuel to be
discharged from the filler neck.
If the narrow filler nozzl e fitted to pumps
delivering unleaded petrol is fully inserted into
the filler neck the misfue l protection device will
activate.
Note: The spout on some fuel cans and older
fuel pumps may trigger the misfuelling device.
When activated, the ye llow protection device
will be visible inside the filler neck. It will
prevent fuel flow into the tank. Before fuelling
can continue with the correct fuel the device
will need to be reset.
The reset tool is stored in the luggage
compartment clipped onto the battery retaining
bar.

DIESEL PARTICULATE FILTER (DPF)
Diesel vehicles equipped with a particle filter
have more efficient emission control. The
particles in the exhaust gases are collected in
the filter during normal driving.
When a DPF message is displayed, the filter
requires a regeneration cy cle to clean itself.
This requires the engine to have reached
normal operating temp erature. Regeneration
takes place automatically at an interval of
approximately 300-900 km (190-560 miles)
depending on driving c onditions. Regeneration
normally takes 10-20 minutes and is
automatically requested by the engine control
module if the vehicle is driven steadily at
vehicle speeds between 40mph to 70mph. It is
possible that the rege neration process will
occur at lower vehicle speeds, but the events
may take a little longer at a 50 km/h (30mph)
average speed.
DRIVING SHORT DISTANCES OR IN
COLD WEATHER
If the vehicle is fre quently driven short
distances or in cold weather conditions then
the engine may not re ach normal operating
temperature. This means that regeneration of
the diesel particle filter does not take place and
the filter is not efficiently cleaned. When the
filter reaches a condition when a filter
regeneration is approp riate and the current
drive style is not appropriate, a warning
triangle on the instrument panel illuminates,
and the message DPF Full. See manual is
displayed on the instrument panel. This is not
indicating a fault conditi on with the vehicle and
no dealership support should be required. Start
regeneration of the filter by driving the vehicle,
preferably on a main road or motorway. The
vehicle should then be driven for approximately
20 minutes or more. When regeneration is complete the warning
text is cleared automatically.
Note:
A small increase in fuel consumption
may be noticed temporarily during
regeneration.
ARDUOUS DRIVING CONDITIONS
When a vehicle is operated in severe or
arduous conditions, more frequent attention
must be paid to servic ing requirements. Refer
to your Service Portfolio for details or contact
your Dealer/Authorised Repairer for advice.
SAFETY IN THE GARAGE
If the vehicle has been driven
recently, do not touch exhaust and
cooling system co mponents until the
engine has cooled.
Never leave the engine running in an
unventilated area.
Do not work beneath the vehicle with a
jack as the only means of support.
Keep your hands and clothing away
from drive belts, pulleys and fans.
Some fans may continue to operate
after the engine has stopped.
Remove metal wrist bands and
jewellery, before working in the
engine compartment.
Do not touch electrical leads or
components while the engine is
running, or with the starter switch
turned on.
Do not allow tools or metal parts of the
vehicle to make contact with the
battery leads or terminals.
