Roadside repairs0•9
When all else fails, you may find yourself
having to get a tow home – or of course you
may be helping somebody else. Long-distance
recovery should only be done by a garage or
breakdown service. For shorter distances, DIY
towing using another car is easy enough, but
observe the following points:
MUse a proper tow-rope – they are not
expensive. The vehicle being towed must
display an ‘ON TOW’ sign in its rear window.
MAlways turn the ignition key to the ‘on’
position when the vehicle is being towed, so
that the steering lock is released, and that the
direction indicator and brake lights will work.
MOnly attach the tow-rope to the towing
eyes provided. On some models with energy-
absorbing bumpers there are no front towing
eyes; on these vehicles the tow-rope shouldbe attached around the rear arm of the lower
control arm so that the rope passes on the
inside of the coil spring.
MBefore being towed, release the handbrake
and select neutral on the transmission.
MNote that greater-than-usual pedal
pressure will be required to operate the
brakes, since the vacuum servo unit is only
operational with the engine running.
MOn models with power steering, greater-
than-usual steering effort will also be required.
MThe driver of the car being towed must
keep the tow-rope taut at all times to avoid
snatching.
MMake sure that both drivers know the route
before setting off.
MOnly drive at moderate speeds and keep
the distance towed to a minimum. Drivesmoothly and allow plenty of time for slowing
down at junctions.
MOn models with automatic transmission,
special precautions apply. If in doubt, do not
tow, or transmission damage may result.
Caution: On models with automatic
transmission, if the vehicle is to be towed
with its rear wheels on the ground, and
extra 1.7 litres of fluid should be added to
the transmission, prior to towing (this extra
fluid must be drained before driving the
vehicle). Even with the extra fluid added to
the transmission, do not tow the vehicle at
speeds in excess of 30 mph (50 kmh) or for
a distance of greater than 15 miles (25 km).
If towing speed/distance are to exceed
these limits, then the vehicle must be
towed with its rear wheels off the ground.
Towing
Puddles on the garage floor or drive, or
obvious wetness under the bonnet or
underneath the car, suggest a leak that needs
investigating. It can sometimes be difficult to
decide where the leak is coming from,
especially if the engine bay is very dirty
already. Leaking oil or fluid can also be blown
rearwards by the passage of air under the car,
giving a false impression of where the
problem lies.Warning: Most automotive oils
and fluids are poisonous. Wash
them off skin, and change out of
contaminated clothing, without
delay.The smell of a fluid leaking
from the car may provide a
clue to what’s leaking. Some
fluids are distinctively
coloured. It may help to clean the car and
to park it over some clean paper as an
aid to locating the source of the leak.
Remember that some leaks may only
occur while the engine is running.
Sump oil Gearbox oil
Brake fluid
Power steering fluid
Oil from filter
Antifreeze
Engine oil may leak from the drain plug......or from the base of the oil filter.
Leaking antifreeze often leaves a crystalline
deposit like this.Gearbox oil can leak from the seals at the
inboard ends of the driveshafts.
A leak occurring at a wheel is almost
certainly brake fluid.Power steering fluid may leak from the pipe
connectors on the steering rack.
position, a worn or weak shock absorber is
probably the reason.
4Repeat the above check at each of the
three remaining corners of the vehicle.
Under the vehicle
5Raise the vehicle with a trolley jack and
support it securely on axle stands. See
“Jacking and towing”for proper jacking
points.
6Check the shock absorbers for evidence of
fluid leakage. Make sure that any fluid noted is
from the shocks and not from any other
source. Also check the rubber mounts at each
end for deterioration If the shock absorbers
fail any of the tests above replace the shocks
as a set.
7Check the tyres for irregular wear patterns
and proper inflation. See “Weekly checks”for
information regarding tyre wear.
8Inspect the universal joint between the
steering shaft and the steering gear housing.
Check the steering gear housing for grease
leakage. Make sure that the dust seals and
boots are not damaged and that the boot
clamps are not loose (see illustration). Check
the steering linkage for looseness or damage.
Look for loose bolts, broken or disconnected
parts and deteriorated rubber bushings on all
suspension and steering components (see
illustration). While an assistant turns the
steering wheel from side to side, check the
steering components for free movement,
chafing and binding. If the steering
components do not seem to be reacting with
the movement of the steering wheel, try to
determine where the slack is located.
9Check the balljoints moving each lower arm
up and down with a crowbar to ensure that its
balljoint has no play. If any balljoint does have
play, replace it. See Chapter 10 for the front
balljoint renewal procedure. Check the tie-rod
ends for excessive play.
10Inspect the balljoint and tie-rod end boots
for damage and leaking grease (see
illustration. Replace the balljoints and tie-rod
ends with new ones if they are damaged (see
Chapter 10).
13 Seat belt check
1
1Check the seat belts, buckles, latch plates
and guide loops for any obvious damage or
signs of wear.
2Make sure the seat belt reminder light
comes on when the key is turned on.
3The seat belts are designed to lock up
during a sudden stop or impact, yet allow free
movement during normal driving. The
retractors should hold the belt against your
chest while driving and rewind the belt when
the buckle is unlatched.
4If any of the above checks reveal problems
with the seat-belt system, replace parts as
necessary.Note:Check with your local dealer
service department; the seat belt system
should be covered under the factory warranty.
14 General lubrication
2
1Obtain a good quality, multi-purpose
lithium-base grease. You’ll also need a grease
gun and other materials to properly lubricate
the chassis (see illustration). Occasionallyplugs will be installed rather than grease
fittings. If so, grease fittings will have to be
purchased and installed.
2Look under the car and see if grease fittings
or plugs are installed. If there are plugs,
remove them and buy grease fittings, which
will thread into the component. A dealer or
motor factors will be able to supply the
correct fittings. Straight, as well as angled,
fittings are available.
3For easier access under the car, raise it with
a jack and place axle stands under the
chassis. Make sure it’s safely supported by
the stands. If the wheels are to be removed at
this interval for tyre rotation or brake
inspection, loosen the wheel nuts slightly
while the car is still on the ground.
4Before beginning, force a little grease out of
the nozzle to remove any dirt from the end of
the gun. Wipe the nozzle clean with a rag.
5With the grease gun and plenty of clean
rags, crawl under the car and begin
lubricating all the front suspension parts that
are equipped with a grease fitting.
6Lubricate the rear driveshafts (see
illustration). Wipe each fitting clean and push
the nozzle firmly over it. Pump the gun until
grease is expelled from the U-joint cap seal.
7Wipe away any excess grease from the
components and the grease fitting. Repeat
the procedure for the remaining fittings.

Radio/cassette unit anti-theft system - precaution
Some models are equipped with an audio
system which includes an anti-theft feature, to
deter thieves. If the power source to the unit is
cut, the anti-theft system will activate. Even if
the power source is immediately reconnected,
the radio/cassette unit will not function untilthe correct security code has been entered.
Therefore if you do not know the correct
security code for the unit, do notdisconnect
the battery negative lead, or remove the
radio/cassette unit from the vehicle.The procedure for reprogramming a unit
that has been disconnected from its power
supply varies from model to model - consult
the handbook supplied with the unit for
specific details or refer to your Jaguar dealer. The jack supplied with the vehicle tool kit
should only be used for changing the
roadwheels - see “Wheel changing”at the
front of this manual. When carrying out any
other kind of work, raise the vehicle using a
hydraulic (or “trolley”) jack, and always
supplement the jack with axle stands
positioned under the vehicle jacking points.
To raise the front of the vehicle, place a
block of wood on the jack head and positionthe jack underneath the centre of the front
crossmember. Lift the vehicle to the required
height and support it on axle stands
positioned underneath the vehicle jacking
points on the sills.
To raise the rear of the vehicle, place a
block of wood on the jack head and position
the jack underneath the centre of the rear
crossmember. Lift the vehicle to the required
height and support it on axle standspositioned underneath the vehicle jacking
points on the sills.
The jack supplied with the vehicle locates in
the jacking points on the sills. Ensure that the
jack head is correctly engaged before
attempting to raise the vehicle.
Neverwork under, around, or near a raised
vehicle, unless it is adequately supported in at
least two places.
