The different ial pres s ure s ensor i s located i n t he engi ne compart ment , on t he lower RH si de of the bul khead. The sens or islocated on two st uds and s ecured wit h nuts .
The different ial pres s ure s ensor i s us ed by the DPF software t o monit or the condit ion of t he DPF. Two pi pe connecti ons ont he sens or are connect ed by pipes t o t he inlet and out let ends of t he DPF. The pipes all ow t he s ens or to measure t he inletand outl et press ures of t he DPF.

WARNINGS
Your vehicle has a higher ground
clearance and hence, a higher centre of
gravity than ordina ry passenger cars,
to enable the vehicle to perform in a wide
variety of off-road app lications. An advantage
of the higher ground clea rance is a better view
of the road allowing you to anticipate
problems.
The vehicle is not designed for
cornering at the same speed as
conventional passenge r cars any more
than a low-slung sports car is designed to
perform satisfactori ly under off-road
conditions. If at all possible, avoid sharp turns
or abrupt manoeuvres. As with other vehicles
of this type, failure to operate the vehicle
correctly may result in loss of control or
vehicle roll-over.
The vehicle should no t be parked over
long dry grass or other combustible
material, particul arly during dry
weather. As the heat ge nerated by the exhaust
and emission control systems may be
sufficient to start a fire.
Before exiting the vehicle ensure that P
park is selected and the park brake
applied. When exiting the vehicle
ensure that the remote control is removed
from the vehicle.

Driving hintsGENERAL DRIVING POINTS
Battery charging - red
Illuminates as a bulb check when
the ignition is turned on and
extinguishes once the engine is
running. If it remains on, or illuminates whilst
driving, a fault with the battery charging
system is indicated. Seek qualified assistance
urgently.
Low oil pressure - red
Illuminates as a bulb check when
the ignition is turned on and
extinguishes when the engine is
started. If the indicator remains on, flashes on
and off, or illuminates whilst driving, stop the
vehicle as soon as safety permits and switch
off the engine immediat ely. Seek qualified
assistance before driving. Always check the oil
level when this indicator illuminates.
REDUCED ENGINE PERFORMANCE
Engine management syst em (EMS) fault
Illuminates amber in the
instrument pack when the engine
management system detects a
serious fault - reduce d performance may be
experienced. Avoid high speeds and consult
your Land Rover Dealer/A uthorised Repairer as
soon as possible.
Check engine - petrol models only
Illuminates amber in the
instrument pack as a bulb and
system check when the starter
switch is turned on and extinguishes as soon
as the engine is starte d. Illumination at any
other time indicates that the emission
performance of the engine management
system is impaired - seek qualified assistance.
If the indicator flashes while driving,
immediately reduce e ngine power to avoid
catalytic converter damage.
RUNNING-IN
The engine, gearbox, tyre s, and brakes need
time to bed-in. During the first 800 km (500
miles) it is essential th at the vehicle is driven
with consideration for the running-in process.
During the running in period the following
advice should be followed.
• Limit the engine speed to a maximum of
3000 rpm, and the road speed to a
maximum of 110 km/h (68 mph).
• Do not use full accelerator pedal travel, and
use the gears to avoid over-revving or
labouring the engine.
• Do not use sport mode during the running
in period.
• Avoid rapid accelerati on or heavy braking
wherever possible.
• Ensure that servicing is carried out on
time, and follow any advice regarding use
in arduous conditions.
Note: The advice given for running in will aid
fuel economy, and s hould be adopted as
general driving practice even after the running
in period.
