towing JAGUAR XFR 2010 1.G Workshop Manual

Rear Suspended Tow


When the vehicle is being recovered by rear suspended tow:

The ignition key must be removed from the ignition switch to lock the steering.
The rear wheels must be correctly positioned in the lifting cradle and securely tied down.
Emergency Towing


WARNING: If the engine is not running, the steering will become heavy and the force necessary to effectively apply the
brakes will be greatly increased.


CAUTION: A vehicle with a defective transmission must be towed by rear suspended tow.
When the vehicle is being towed on its own wheels:

Local regulations for the towing of vehicles must be followed. In some countries the registration number of the towing
vehicle and an 'On Tow' sign or warning triangle must be displayed at the rear of the towed vehicle.
The gear selector lever must be in Neutral.
The ignition switch must be in position II to release the steering lock and make the direction indicators, horn and stop
lamps operate.
A distance of 0,8 km (0.5 mile) must not be exceeded.
A speed of 48 km/h (30 mph) must not be exceeded.
The tow rope must be attached to the front towing eye. www.JagDocs.com

engine oil).

Oil Consumption Test

The amount of oil an engine uses will vary with the way the vehicle is driven in addition to normal engine-to-engine variation.
This is especially true during the first 16,100 km (10,000 miles) when a new engine is being broken in or until certain internal
components become conditioned. Vehicles used in heavy-duty operation may use more oil. The following are examples of
heavy-duty operation:

Trailer towing applications
Severe loading applications
Sustained high speed operation
Engines need oil to lubricate the following internal components:
Cylinder block cylinder walls
Pistons and piston rings
Intake and exhaust valve stems
Intake and exhaust valve guides
All internal engine components

When the pistons move downward, a thin film of oil is left on the cylinder walls. As the vehicle is operated, some oil is also
drawn into the combustion chambers past the intake and exhaust valve stem seals and burned.
The following are examples of conditions that can affect oil consumption rates:
Engine size
Operator driving habits
Ambient temperatures
Quality and viscosity of oil
Engine is being run in an overfilled condition (check the oil level at least five minutes after a hot shutdown with the
vehicle parked on a level surface. The oil level should not be above the top of the cross-hatched area and the letter "F"
in FULL).

Operation under varying conditions can frequently be misleading. A vehicle that has been run for several thousand miles on
short trips or in below-freezing ambient temperatures may have consumed a "normal" amount of oil. However, when checking
the engine oil level, it may measure up to the full mark on the oil level indicator due to dilution (condensation and fuel) in the
engine crankcase. The vehicle then might be driven at high speeds on the highway where the condensation and fuel boil off.
The next time the engine oil is checked it may appear that a liter of oil was used in about 160 km (100 miles). Oil
consumption rate is about one liter per 2,400 km (1,500 miles).

Make sure the selected engine oil meets Jaguar specification and the recommended API performance category "SG" and SAE
viscosity grade as shown in the vehicle Owner's Guide. It is also important that the engine oil is changed at the intervals
specified for the typical operating conditions.
The following diagnostic procedure is used to determine the source of excessive oil consumption.


NOTE: Oil use is normally greater during the first 16,100 km (10,000 miles) of service. As mileage increases, oil use
decreases. High speed driving, towing, high ambient temperature and other factors may result in greater oil use.

1. Define excessive consumption, such as the number of miles driven per liter of oil used. Also determine customers
driving habits, such as sustained high speed operation, towing, extended idle and other considerations.
2. Verify that the engine has no external oil leaks as described under Engine Oil Leaks in this section.
3. Carry out an oil consumption test:
Run the engine to normal operating temperature. Switch engine OFF and allow oil to drain back for at least five
minutes .
With vehicle parked on level surface, check the engine oil level.
If required, add engine oil to set level exactly to the FULL mark.
Record the vehicle mileage.
Instruct the customer to return for a level check after driving the vehicle as usual for 1,610 km (1000 miles).
Check the oil level under the same conditions and at the same location as the initial check.

NOTE: If the oil consumption rate is unacceptable go to Step 4.

4. Check the Positive Crankcase Ventilation (PCV) system. Make sure the system is not plugged.

5. Check for plugged oil drain-back holes in the cylinder head and cylinder block.
6. If the condition still exists after carrying out the above tests go to step 9.

7. Carry out a cylinder compression test. Refer to the Compression Test procedure in this section. This can help determine
the source of oil consumption such as valves, piston rings or other areas.
8. Check valve guides for excessive guide clearance. Install new valve stem seals after verifying valve guide clearance.

9. Worn or damaged internal engine components can cause excessive oil consumption. Small deposits of oil on the tips of
the spark plugs can be a clue to internal oil consumption.

Anti-Theft - Active - Anti-Theft - Active - Overview
Description and Operation

Overview Published: 11-May-2011

The active anti-theft system is available with three different levels of vehicle protection depending on market specification:

Hinged panel sensing
Hinged panel and intrusion sensing
Hinged panel, intrusion and inclination sensing.

The CJB (central junction box) automatically arms and disarms the active anti-theft system when it functions the central
locking system.
Refer to: Handles, Locks, Latches and Entry Systems (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).
Depending on market specification two modes of protection are used: perimeter mode and volumetric mode.

Perimeter mode
Perimeter mode, monitors the security of the hinged panels, which include:
all doors,
luggage compartment lid, and
engine compartment lid.

When perimeter mode is active, the CJB monitors the panel ajar switches in the latch mechanisms of the hinged panels.
Volumetric mode

In volumetric mode the CJB monitors the interior of the vehicle for movement using an ultrasonic sound wave sensor.

If the battery backed sounder incorporates an inclination sensor the vehicle will also be monitored for unauthorised tilting; for
example towing or jacking.
