Quick start
L
Sand Suitable for soft, predominantly dry,
yielding sandy ground, e.g. sand
dunes and deserts. If the sand is
damp or wet the Mud-Ruts program may be
more beneficial.
Parking aid
With the ignition on, the front and rear parking
sensors are activated whenever reverse gear is
selected. A short confirmation tone will sound
after one second.
If an obstruction is detected by the sensors, an
intermittent tone will sound (higher pitch for
objects detected by the front sensors). As the
vehicle moves closer to the obstruction the
intermittent tone in creases in frequency.
When the distance between the sensor and the
obstruction is less than approximately 30 cm
(1 foot) the tone becomes continuous.
The parking aid is automatically switched off
when the vehicle's forward speed exceeds 16
km/h (10 mph). Front parking aid - manual operation
When driving into a limited space, the front
parking aid can be ma nually activated by
pressing the switch on the facia. The switch
will illuminate and a short confirmation tone
will sound.
Wading
When wading through water, select the
program suitable for the surface beneath the
water.
The maximum depth of water should not
exceed 500 mm (19.7 inches).

Parking aidPRINCIPLE OF OPERATION
Park Distance Control (PDC) provides the
driver with informatio n on most obstructions,
and their distance from the vehicle, when
manoeuvring. PDC does this by using four
ultrasonic sensors on each bumper.
1. When objects are detected at this range the
PDC will emit a pulse tone which increases
in frequency as the vehicle gets closer to
the object.
2. When objects are sensed within this range,
approximately 30 cent imetres (12 inches)
the tone becomes continuous.

USING THE PARKING AID
PDC activation
Front PDC is activate d by pressing the PDC
button a short confirmation tone will be heard,
and the tell-tale will illuminate. The front
sensors will remain active as long as the
vehicle's speed does not exceed 16 km/h (10
mph).
If reverse gear is selected, front and rear
sensors are activated. In vehicles fitted with automatic transmission,
selecting neutral from re verse will keep front
and rear sensors active.
Front PDC deactivation
The PDC system can be deactivated by
pressing the PDC switch.
Towing
The rear sensors are au tomatically disabled
when a trailer is connected.
Sensor care
The sensors should be ke pt clean to maintain
accuracy and performance.
System fault
If a system fault is detected, a long
high-pitched tone will sound, and the switch
indicator lamp will fl ash. Contact your Land
Rover Dealer/Authorised Repairer as soon as
possible.
WARNING
Parking aids may not detect moving
objects such as children and animals
until they are dangerously close.
Always use extreme caution when
manoeuvring.
CAUTIONS
Parking aids are for guidance only, and
are not intended to replace the driver's
visual checks for obstructions when
manoeuvring.
PDC sensors may not detect some
obstructions. Obstru ctions such as
narrow posts, small objects close to the
ground, and some objects with dark
non-reflective surfaces for example.
Systems which use the same frequency
band as the front PDC sensors may
cause irregular tones to be emitted.

CAUTION
When washing the vehicle do not aim
high pressure water je ts directly at the
sensors. Do not use abrasive materials
or hard/sharp objects to clean the sensors.
Only use approved vehicle shampoo.

that the towing vehicle, and the trailer are being
used correctly, and in accordance with
manufacturers recomm endations and any
applicable legislation.
Trailer electrical connection
Note: The rear parking sensors are
automatically disabled when the trailer
electrical conne ction is made.
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.

WARNINGS
Never exceed the maximum weights for
either the vehicle, or the trailer. Doing
so can cause accelerate d wear and damage to
the vehicle. It can also adversely affect vehicle
stability and braking, which in turn can lead to
loss of control and incr eased braking distance
resulting in a rollover or crash.
To preserve handling and stability, only
fit Land Rover 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.
CAUTION
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.
