Regular Checks
In the interests of safety and reliability,
it is advisable to carry out the following
checks at the recommended intervals,
and always before starting on a long
journey.
Daily
Check that there is sufficient fuel for the
journey intended, particularly at night
and before joining motorways.
Weekly
Tyres– Check the tyres, including the
spare, for condition and pressure.
Tyre pressures are explained on page 8 - 8
and shown on a label inside the fuel filler
flap.
Lights – Check that all exterior lights and
direction indicators function correctly
and that the lenses are clean.
Engine oil – With the vehicle standing
on level ground, check the oil level and
top up if necessary with oil of the correct
grade.
Engine coolant – With the engine cold,
check the level of the coolant in the
coolant reservoir header tank. Any loss of
fluid must be checked by a Jaguar
Retailer. Brake fluid
– Check the level of the fluid
in the brake fluid reservoir. Top up if
necessary with new, unused Jaguar
approved brake fluid.
The reservoir is initially nearly full,
but the level will drop as the brake pads
wear. If the level appears unusually low,
location of the fluid leakage must be
checked by a Jaguar Retailer.
Power steering fluid – With the engine
cold, check the level of the fluid in the
power steering fluid reservoir. Top up if
necessary with fluid of the correct
specification. Any loss of fluid should be
checked by a Jaguar Retailer.
Windscreen washer fluid – Top up
with windscreen washer fluid and clean
soft water. Check the operation of the
washers. It is recommended that you
use Jaguar Windscreen Washer Fluid to
keep the glass clean and also to prevent
the fluid from freezing during cold
weather.
Monthly
Wiper blades – Check the quality of the
wipe. If smearing or juddering is evident,
clean the windscreen and wiper blades.
Used Engine Oil
!WARNING:
Prolonged and repeated contact may
cause serious skin disorders,
including dermatitis and cancer.
Always use a hand cream to protect the
skin from oil contamination.
Avoid contact with the skin as far as
possible and wash thoroughly after any
contact. Keep oils out of reach of
children.
PROTECT THE ENVIRONMENT: It is
illegal to pollute drai ns, watercourses and
soil. Use authorised waste collection
facilities, including civic amenity sites and
garages providing fa cilities for the
disposal of used oi l, oil filters and
batteries. If in doubt, contact your Local
Authority for advice on disposal.

Hood Release
!WARNING:
Take care to keep away from rotating components if the
engine is running when you open the hood.
Release the hood lock by pullin g the lever below the fascia on
the left-hand side of the vehicle.
Lift the hood slightly and push the safety catch, located under
the centre of the front edge of th e hood. The gas filled struts will
assist raising the hood, and retain it in the fully open position.
!WARNING:
Before closing the hood ensure that no-one is obstructing
the closing area and that hands and clothes are clear.
Remove tools, cleaning cloths, etc., from the engine
compartment.
Close the hood to within a distance of 12 to 14 inches
(30 to 35 cm) of the fully closed position, then let go to allow
the hood to shut. Check by pulling the hood that both the right-
hand and left-hand latches are engaged.

Battery lead disconnection
Caution:
1. Under no circumstances should a battery be discon nected whilst
the ignition circuit is live,
as permanent damage to the
instrument cluster may occur.
2. Disconnect the negative lead (earth terminal) first.
Fold the luggage compartment floor panel
forwards (see page 6 - 4).
Slacken the negative lead pinch bolt and
disconnect the negative (–) battery lead.
Slacken the positive lead pinch bolt and
disconnect the positive (+) battery lead. Battery lead connection
Note:
Upon battery reconnection the
security system will be armed. Opening
any protected entry will sound the alarm.
Make sure that a key or key transmitter is
available.
Caution: Do not overtighten the
pinch bolts.
Clean the battery posts and coat the post
bases with petroleum jelly.
Connect the positive (+) lead, tighten the
pinch bolt and clip the positive terminal
cover on the battery. Connect the
negative (–) lead and tighten the pinch
bolt.
After the battery ha s been reconnected
and the ignition swit ch is turned to
position ‘II’, the message centre display,
if fitted, will initially show an erroneous
reading i.e.––––––. Thiswill remain
until after the bulb check sequence, when
the correct recorded mileage will be
displayed. This is a normal function of the
instrument cluster.
After battery reconnection
After reconnecting the battery:
• Reset the electric parkbrake; refer to Parkbrake on page 4 - 34. • Reset the electrically operated
windows anti-trap function; refer to
Window Anti-trap Protection on
page 4 - 30.
• The trip computer will lose all recorded trip data and all trip
functions will be reset to zero.
The vehicle total odometer reading is
retained.
• If the battery is disconnected for more than 72 hours the radio preset
channels will need to be reset.
• Where fitted, the TV preset channels may need to be reset. Refer to the
Jaguar Touch-screen Handbook.
• Reset the clock to the correct time.
The engine electronic control system
adapts to certain characteristics of the
vehicle. These adaptations are lost if the
battery is disconnected.
On reconnection, therefore, some slightly
abnormal drive symptoms may occur and
the vehicle may need to be driven
10 miles (16 kilometres) or more while
the control system re-adapts.
