7 - 6 Maintenance
Checking and Top Up
Check Engine Oil Level
Check the oil level regularly with the vehicle on flat, level
ground.
Refer to page 7 - 5 for dipstick and oil filler locations.
It is preferable to check the oil level after the vehicle has been
standing, that is, with th e engine completely cold.
If the engine has been started do not check the oil level until the
engine has reached normal operating temperature. Stop the
engine and wait for a minimum of 5 minutes to allow the oil to
drain back into the sump.
Remove the dipstick ( A) and wipe clean with a non-fluffy cloth.
Replace fully, then wi thdraw the dipstick. If the oil level is above
the lower of the two dots on the dipstick then no additional oil
is required.
If the oil level reaches the lower of the two dots, remove the oil
filler cap ( B) and add oil, to the quantity and specification
shown on the next page.
Refit the filler cap and hand tighten securely.
Caution: Do not use oil additives of any type. Use only
specified lubricants.

Maintenance 7 - 7
Recommended Engine Oil
When the oil level is at the lower dipstick mark, add 1 US quart
(1.0 litre) of oil.Oil specification
– API SJ/EC and ILSAC GF–3
When topping up between oil chan ges, make sure that you use
oil that has the correct quality le vel (API service) and viscosity
grade. Your vehicle’s warranty ma y be invalidated if damage is
caused by use of improper engine oil.
For maximum fuel economy, 5W–30 oil is recommended.
SAE viscosity rating
For climates ranging from –22°F (–30°C) and +122°F (+50°C),
the following oil viscosities may be used:
0W–30
5W–30 (preferred)
0W–40
5W–40
Note: It is recommended that the oil level is topped up using oil
of the same viscosity. If you are unsure which oil viscosity is used
in your car, your Jaguar Retailer will be able to advise.
If you are operating this vehicle in climates outside the above
temperature range, contact your Jaguar Retailer for advice.

7 - 8 Maintenance
Check Power Steering Fluid
Level
Caution: It is imperative that the
power steering system does not
become contaminated in any way.
Always dispense fluid from a fresh
sealed container and clean the area
around the reservoir neck both
before and after topping up.
Never return drained fluid to the
system.Refer to page 7 - 5 for power steering fluid
reservoir location.
Check the fluid level when the engine is
‘COLD’ and the vehicle is on a flat, level
surface.
The fluid is visible through the
translucent casing of the reservoir.
Check that the fluid level is between the
MIN and MAX marks on the side of the
reservoir.
If necessary, top up with power steering
fluid as specified by your Jaguar Retailer.
Wipe clean and remove the filler cap
from the reservoir;
take great care to
prevent any foreign matter from entering.
DO NOT OVERFILL.
Refit the filler cap.
Should the level be ve ry low, report the
loss of fluid to the nearest Jaguar Retailer.
!WARNING:
1. Do not allow power steering fluid to make contact with skin or eyes.
If this happens, rinse the affected
area immediately with plenty of
water.
2. Power steering fluid is toxic and flammable. Be sure to observe all
warnings indicated on the power
steering fluid container.

Maintenance 7 - 11
Check Coolant Level
Refer to page 7 - 5 for coolant header tank
location.
The coolant level MAX and MIN
indicators are located inside the reservoir
and are only visible when looking into the
filler neck with the cap removed. Check
the level only when the engine is cold.
The coolant level shou ld be between the
MAX and MIN indicators. If persistent
coolant loss is noticed, have a Jaguar
Retailer investigate the cause
immediately.
!WARNING:
Do not remove the coolant header
tank filler/pressure cap while the
engine is hot. If the cap must be
removed, protect the hands against
escaping steam and slowly turn the
cap anti-clockwise until the steam
starts to escape. Leave the cap in this
position until the pressure is
released, and then remove the cap.
Topping up
!WARNING:
Do not allow anti-freeze to make
contact with skin or eyes. If this
happens, rinse the affected area
immediately with plenty of water.
Caution: Anti-freeze will damage
paintwork. Avoid spillage.
Top up with a mixture of 50% water and
50% anti-freeze until the coolant is
between the MAX and MIN indicators
inside the header tank. Use anti-freeze to
specification WSS M97B44, coloured
orange, Extended Life Coolant.
Refit the filler cap and hand-tighten
securely until the ratchet operates. Engine anti-freeze
When used at the correct concentration,
anti-freeze not only protects the engine
from frost damage in winter, it also
provides all year round protection against
internal corrosion.
The cooling system should always be
topped up or refilled with the specified
anti-freeze at the correct concentration.
This 50/50% mixture gives frost
protection for temperatures down to
–40°F (–40°C).
Do not mix any other anti-freeze with
that specified; inferior quality anti-freeze
may be ineffective in maintaining
adequate frost and corrosion protection
to the cooling system.
The coolant solution
may remain in the
cooling system for five years or
156,000 miles (250,000 km) after which
the system should be drained, flushed
and refilled.
Engine block heater
For further information consult your
Jaguar Retailer.
Caution: The fitting of an engine
block heater does not eliminate the
need for anti-freeze under freezing
conditions.

Maintenance 7 - 13
Battery
A low maintenance battery specifically
designed for use with this vehicle is fitted
below the luggage compartment floor.
!WARNING:
California Proposition 65:
Battery posts, terminals and related
accessories, contain lead and lead
compounds. Wash hands after
handling.
!WARNING:
1. The cell plugs and vent pipe must
be in place at all times when the
battery is in the vehicle. Failure to
fit, or incorrect fitting of these
items is potentially hazardous.
2. To avoid injury do not use an open flame or cause an electric spark
when checking the battery.
Hydrogen gas generated by the
battery is flammable and may
explode. 3. Do not connect any 12 volt
equipment (for example a 12 volt
lead lamp) directly to the battery
terminals. Use the accessory
sockets to temporarily connect
Jaguar approved accessories.
4. Do not let battery acid electrolyte come into contact with skin or
eyes. If you get any in your eyes or
on your skin, immediately rinse
with cold water and consult a
doctor.
Caution:
1. Switch off the ignition before disconnecting battery terminals.
Always disconnect the earth
terminal first and reconnect last.
2. Do not let battery acid come into contact with painted surfaces or
fabric.
The exterior of the battery should be
occasionally wiped clean to remove any
dirt or grease.
If a new battery is to be fitted, it must be
the same type as the original.
The use of unapproved batteries is not
recommended and coul d invalidate the
vehicle warranty. Note:
The service life of the battery is
dependent on its condition of charge.
It must always be sufficiently charged for
the battery to last an optimum length of
time.
We recommend that the battery charge is
checked frequently if the vehicle is used
mostly for short distance trips, or if it is
not used for long periods of time.
Battery/ignition isolator switches
Non-approved battery isolator switches,
which disconnect the power supply to all
electrical circuits, are not recommended.
Generator
To prevent damage to the generator,
do not run the engine while the battery
or any of the charging circuit cables are
disconnected.
The generator has polarity-sensitive
components that may be irreparably
damaged if subjected to incorrect
polarity. Ensure that the battery earth
lead is always connected to the battery
negative terminal.

7-16 Maintenance
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.
