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.

FUEL CONSUMPTION
The fuel consumption figures shown below have been calculated using a standard testing
procedure (the new EC test proc edure from Directive 99/100/EC), and produced in accordance with
The Passenger Car Fuel Cons umption (Amendment) Order 1996.
Under normal use, a vehicle's actu al fuel consumption figures may differ from those achieved
through the test procedure, de pending on driving technique, ro ad and traffic conditions,
environmental factors, ve hicle load and condition.
Urban cycle
The urban test cycle is carried out from a cold start and cons ists of a series of accelerations,
decelerations and periods of stea dy speed driving and engine idling. The maximum speed attained
during the test is 50 km/h (30 mph) with an average speed of 19 km/h (12 mph).
Extra-urban cycle
The extra-urban test cycle is carried out immediatel y after the urban test. Approximately half of the
test comprises steady-speed driving, while the re mainder consists of a series of accelerations,
decelerations and engine idling . The maximum test speed is 120 km/h (75 mph) and the average
speed 63 km/h (39 mph). The test is carried out over a distance of 7 km (4.3 miles).
Combined
The combined figure is an average of the urban an d extra-urban test cycle results, which has been
weighted to take account of the differ ent distances covered during the two tests.
For additional information on fuel consumption figures and exhaust emissions, visit the Vehicle
Certification Agency (VCA) website at http://www.vcacarfueldata.org.uk/.

Weekly checks
•Engine oil level (non- electronic dipstick
vehicles). See ENGINE OIL CHECK - V6
Petrol engines (page 197).
• Engine coolant check. See ENGINE
COOLANT CHECK (page 204).
• Brake fluid level. See BRAKE FLUID
CHECK (page 206).
• Power steering fluid level. See POWER
STEERING FLUID CHECK (page 208).
• Screen washer fluid level. See WASHER
FLUID CHECK (page 209).
• Tyre pressures and condition. See TYRE
CARE (page 217).
• Operate air conditioning. See AUTOMATIC
CLIMATE CONTROL (page 116).
Note: The engine oil level on V6 petrol engines,
should be checked more frequently if the
vehicle is driven for prolonged periods at high
speeds. The engine oil level on diesel and V8
petrol engines is checked automatically at all
times by the electronic dipstick.
Severe driving conditions
When a vehicle is operated in severe
conditions, more frequent attention must be
paid to servicing requirements.
Severe driving conditions include:
• Driving in dusty and/or sandy conditions.
• Driving on rough and/or muddy roads
and/or wading. •
Driving in extremely hot or cold
conditions.
• Driving in areas using road salt or other
corrosive materials.
• Towing a trailer or driving in mountainous
conditions.
Contact your Dealer/Authorised Repairer for
advice.
Emission control
Your vehicle is fitted with various items of
emission and evaporati ve control equipment,
designed to meet specific territorial
requirements. You should be aware that
unauthorised replacemen t, modification or
tampering with this equipment by an owner or
repair shop, may be unlawful and subject to
legal penalties.
In addition, engine se ttings must not be
tampered with. These have been established to
ensure that your vehicle complies with
stringent exhaust em ission regulations.
Incorrect engine settings may adversely affect
exhaust emissi ons, engine performance and
fuel consumption. The y may also cause high
temperatures, which will result in damage to
the catalytic converter and the vehicle.
Road testing dynamometers (rolling
roads)
Because your vehicle is equipped with anti-lock
brakes, it is essential that any dynamometer
testing is carried out only by a qualified person,
familiar with the dynamometer testing and
safety procedures practised by
Dealers/Authorised Repairers.
CAUTION
Ensure that you take notice of any
message centre information and
warnings relating to engi ne oil level (V8 petrol
and diesel engines only). Top-up the level
when advised to do so. See ENGINE OIL
CHECK - V8 Petrol engines (page 199).

Wheels and tyres
218

All of the vehicle's tyres (including the spare)
should be checked regularly for damage, wear
and distortion. If you are in any doubt about the
condition of a tyre, have it checked immediately
by a tyre repair centre or your
Dealer/Authorised repairer.
Checking the tyre pressures
The recommended tyre pressures are listed on
a placard label fixed to the end of the left-hand
side door. These pressures provide optimum
ride and handling charac teristics for all normal
operating conditions.
If winter tyres are fitted, please refer to the
winter tyre pressure information. SeeUSING
WINTER TYRES (page 223).
In the interest of safe ty, reliability and fuel
efficiency, check the tyres, including the spare,
for condition and pressu re on a weekly basis
and before long journeys.
Do not check tyre pressures immediately after
the vehicle has travelled in excess of 1.6 km
(1.0 mile). Tyre temperatures and pressures
increase when running. Deflating a warm tyre
to the recommended pressure will result in
under-inflation.
If tyre pressures are checked while the vehicle
is inside a protected covered area, e.g. a
garage, and subsequent ly driven in lower
outdoor temperatures, tyre under-inflation
could occur.
A slight pressure loss occurs naturally with
time. If this exceeds 0.14 bar (2 lbf/in², 14 kPa,)
per week, have the cause investigated and
rectified by qualified assistance.
Tyre pressures (including the spare) should be
checked at least once a week with normal
on-road use, but should be checked daily if the
vehicle is used off-road. Always check the tyre
pressures before setti ng off on a long journey.
If it is necessary to check tyre pressures when
the tyres are warm, you should expect the
pressures to have increased by up to
0.3-0.4 bar (4-6 lbf/in², 30-40 kpa). Do not
reduce the tyre pressures to the cold inflation
pressure under these circumstances. Allow the
tyres to cool fully before adjusting the
pressures.
If the vehicle has been parked in
strong sunlight, or used in high
ambient temperatures do not reduce
the tyre pressures. move the vehicle into the
shade and allow the tyres to cool before
re-checking the pressures.
WARNING
Tyre pressures should be checked
regularly using an accurate pressure
gauge, when the tyres are cold.
Failure to properly maintain your tyre
pressures could increase the risk of tyre failure
resulting in loss of vehicle control and
personal injury.
