Starting/Stopping the
Vehicle
When the vehicle is stationary the
automatic gear selector may be left in ‘D’,
‘ 2 ’, ‘ 3’, ‘ 4’ or ‘ 5’, unless the vehicle is to
be parked. When stopping for traffic
lights, junctions etc., either select ‘ P’ or
apply the parkbrake and select ‘ N’.
Before Starting
Before starting the engine, new owners/
drivers should familiarize themselves with
the layout and operation of the controls
and instruments.
!WARNING:
Before attempting to start the engine,
check parkbrake is ON and gear
selector lever is in position ‘P’ or ‘N’.
To Start the Engine
The engine cannot be started until the
gear selector is in ‘ N’ or ‘ P’.
Insert the key into the ignition switch and
turn clockwise to position ‘II’ to switch
on the ignition.
When the key is turned to position ‘III’
the starter motor will turn the engine
until:
• The key is released and automatically returns to position ‘II’.
• The ignition switch is turned to ‘0’ or ‘I’.
• The gear selector is moved out of ‘P’ or ‘N’.
• The engine starts.
If the engine fails to start, the key must be
turned to position ‘0’ before attempting
to restart.
Do not use the starter continuously for
longer than six seconds. Continued use of
the starter will disc harge the battery and
may damage the starter mechanism.
Wait until the engine stops turning before
re-using the starter.
When the engine starts, release the key. The red charge light and the oil pressure
light in the instrument cluster should go
out when the engine is running.
If the engine fails to start
If an ignition key is placed in the ignition
switch and turned to position ‘II’ and the
alarm security light is flashing, it is
possible that the engine will not start.
In any event, please contact a Jaguar
Retailer to investigate the cause of the
light flashing.
It is possible that the fuel system inertia
switch may have tripped, see page 6 - 3
for the resetting procedure.
If the engine persistent
ly fails to start and
flooding is suspected, depress the
accelerator pedal fully, hold it in this
position and turn the key to position ‘III’
for six seconds. Release the key, remove
your foot from the accelerator pedal and
then attempt to restart the engine.
Note: The engine cannot start whilst the
pedal is fully depressed, it must be
released to enable the engine to start.
If the engine still fail s to start, switch the
ignition OFF and contact a Jaguar
Retailer.

4-44 On the Road
Note:
1. After selecting forward or reverse drive ranges from Neutral or Park,
wait briefly for th e transmission to
engage before accelerating.
2. When in Neutral or Park the engine can only be a ccelerated to
4500 rev/min.
R = Reverse – Do not select if the vehicle
is moving forward.
The reversing lights come ON
automatically when reverse gear is
selected and the ignition switch is in
position ‘II’.
D = Drive – All six gears are changed
automatically as required by the throttle
position and road speed.
2, 3, 4, 5 = If selected, the transmission
operates automatically in second, third,
fourth or fifth gear but will not engage
gears higher than the one selected. Drive to fifth
When driving in gear position ‘D’ with
sixth gear engaged, the gear selector can
be shifted sideways across the gate to ‘
5’.
Provided that the vehicle’s speed is not
too great, the transmission will shift
down to fifth. Sixth gear will be inhibited
until the gear selector is moved back to
‘D’.
Hill climbing and engine braking
When driving on roads with long
downhill gradients, selecting ‘3’ or ‘2’
(depending on road/traffic conditions)
will give engine braking.
When the gear selector is moved
from ‘D’, ‘5’, ‘4’ or ‘3’ down to ‘2’,
downshift to second ge ar will only take
place at appropriate road speeds.
Reverse inhibit
Reverse is inhibited when the vehicle is
moving forward at speeds above 5 mph
(8 km/h).
Note: Reverse inhibit will not function in
limp-home mode. Kickdown
Kickdown is operated when the pedal is
pressed fully down, beyond the normal
operating range and against a spring
pressure, to provide maximum engine
performance. Kickdown is used in
circumstances where rapid acceleration is
required, such as when overtaking.
Kickdown causes the transmission to
change down to the lowest gear possible
to achieve maximum acceleration.
The gear engaged depends on the road
speed at the time of kickdown.
As well as shifting
down, the gearshift
points are extended to give greater
performance. This mode is in effect for as
long as the pedal is pressed fully down.

On the Road 4 - 45
Limp-home mode
In the unlikely event of an electrical or
mechanical failure, transmission
operation will be impaired. The vehicle
gear selector ranges P, R, N, D can still be
used to enable the vehicle to be driven to
a safe area. In this event consult a Jaguar
Retailer immediately.
!WARNING:
The driver should be aware that the
vehicle’s performance will be
reduced and must take this into
account when driving.
Sport Mode
The switch marked ‘S ’ on the ‘J’-gate
surround enables the driver to select
either normal or sport (S) modes.
When sport mode is selected the
automatic transmission will operate
normally, but the ge arshift points are
extended to make full use of the engine’s
power reserves.
To select ‘Sport’, press the switch. A red
light within the switch is illuminated to
indicate that sport mode has been
selected.
To cancel ‘Sport’, press the switch again. Note:
Both sides of the ‘J’-gate can be
used irrespective of the transmission
mode, e.g. with ‘S’ selected the
transmission can be operated in full
automatic or by manual selection.
In addition to norm al and sport modes,
the transmission control computer will
select shift patterns to suit specific
conditions.
Cruise Control – When cruise control is
operating at set speed the transmission
selects a shift pattern to suit cruise
control operation.
DSC – When DSC is switched ON and the
system is activated, the transmission
selects a shift pattern to suit traction
control conditions.
Gradients – When the vehicle is being
driven on roads with uphill gradients,
the transmission adapts the shift pattern
to make better use of engine power and
aid engine cooling.
Note: Under the conditions described,
the relevant transmission mode will
override the normal or sport modes
selected by the driver.
When such conditions no longer exist,
the transmission will revert to the shift
pattern previously selected by the driver,
that is, normal or sport.
