The Jaguar Sequential Shift mode also
has the following features:
Kick-down: Operation of kick-down in
Jaguar Sequential Shift mode will
over-ride the currently selected gear. The
lowest available gear will be selected for
maximum acceleration and will be
highlighted in the message centre display.
Subsequent manual shifts may then be
selected as usual.
Positive torque: Provides throttle blips
on down-shifts, improving shift feel and
response.
Shift assist: The transmission will
automatically up-shift at the engine speed
redline in Jaguar Sequential Shift mode
as if commanded manually.
The transmission will automatically
down-shift when the engine rpm drops
too low for the currently selected gear.
When the vehicle approaches, or comes
to rest, second gear is automatically
selected.
Subsequent pullaways will occur in
second gear, unless the accelerator pedal
demand is high or a down-shift is
manually selected, in which case, first
gear will be selected.
In all cases the message centre will
display the current gear.
Note: If a down-shift is requested which
would normally result in an engine speed
outside the normal operating range during
sustained braking the transmission will
indicate and hold the requested gear in
the message centre display. The
transmission will then commence the
down-shift when the engine speed is
within the normal operating speed.

WARNING:
The driver should be aware that the
vehicle’s performance will be reduced
and must take this into account when
driving. Also the use of the Jaguar
Sequential Shift paddles will be
disabled. In this event consult a Jaguar
Dealer immediately.
In the unlikely event of an electrical or
mechanical failure, transmission
operation will be limited. The vehicle gear
selector ranges P, R, N, D can still be
used to enable the vehicle to be driven to
a safe area.
Message centre display
The message centre may display the
following messages with associated
warning indicators:
ENGINE SYSTEMS FAULT (Red)
RESTRICTED PERFORMANCE (Red or
Amber)
TRANSMISSION FAULT (Amber)
If any of these messages are displayed it
is likely that loss of power or driveability
will be experienced. Seek qualified
assistance as soon as possible.
Final drive unit
Caution: Although the final drive unit is
a fill for life unit, if your vehicle is used
for a race event or test track day, then
following the event the final drive unit
lubricant should be changed. Contact
your Jaguar Dealer.
