Jaguar S-Type. Service manual - part 32






To select Sport mode, press the switch. A 
red light within the switch is illuminated to 
indicate that Sport mode has been 

To cancel Sport mode, press the switch 

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 the switched transmission 
modes (N and S), the transmission control 
module 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.

Dynamic Stability Control (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.

Under the conditions described above, 
the relevant transmission mode will 
override the N or S modes selected by the 
driver. When such conditions no longer 
exist, e.g. Cruise Control switched OFF, 
the transmission will revert to the shift 
pattern previously selected by the driver, 
i.e. N or S.

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.


Braking System


Braking System


This system helps to prevent the road 
wheels from locking and skidding during 
emergency braking, assisting the driver to 
maintain full steering and directional 

The factor controlling ultimate stopping 
distance and cornering ability is tire and 
road adhesion.



• It remains the driver’s responsibility 

to drive safely according to 
prevailing conditions.

• The fact that a vehicle is fitted with 

ABS must never allow the driver to 
be tempted into taking risks which 
could affect his or her safety, or 
that of other road users.

• The addition of ABS cannot 

overcome the consequences of 
trying to stop in too short a 
distance, cornering at too high a 
speed, or the risk of aquaplaning.

• The driver should always take road 

conditions into account. A slippery 
road surface always requires more 
braking distance for a given speed, 
even with ABS. A possible increase 
in stopping distance compared to 
locked wheels may occur during 
ABS operation on slushy snow, 
gravel, sand, or some heavily 
corrugated or ridged warning 
sections of road surfaces.

ABS optimises tire to road adhesion 
under maximum braking conditions, 
though it cannot provide increased 
cornering ability. 

There is no need for special braking 
techniques, such as pumping the brakes, 
to achieve optimum braking distances 
and control on poor or slippery road 
surfaces. Tires must be in good condition 
to achieve maximum adhesion.

During normal braking the ABS will not be 
activated. However, if the braking force 
applied begins to exceed tire and road 
adhesion, the ABS will automatically 
activate preventing the road wheels from 

In these circumstances, a pulsating effect 
will be felt from the brake pedal indicating 
that the system is functioning. The 
pulsating effect is due to small 
fluctuations in pressure, supplied to the 
brakes by the system to maintain full tire 
and road adhesion.

Under severe braking on some road 
surfaces, tire noise may be apparent , 
even though the wheels will at no time 
become locked.

ABS Monitoring

The ABS control module monitors the 
ABS electrical system from ignition switch 
ON to ignition switch OFF. Any 
malfunction will be indicated by the 
anti-lock warning indicator coming on.

Should a fault develop in the ABS system, 
the brake system will still operate 
conventionally and with the same 
standard of performance as vehicles not 
equipped with ABS.

Caution: Consult a Jaguar Dealer 
immediately if the warning indicator 
comes on while driving; a system 
failure is indicated.

Braking System



Emergency Brake Assist (EBA)

The EBA system measures the rate at 
which the brake pressure increases. If the 
system detects an emergency braking 
situation, EBA automatically initiates the 
full braking effect. This can reduce 
stopping distances in critical situations, 
which can help an inexperienced driver to 
stop in the same distance as an 
experienced driver.



The EBA system is an additional safety 
system; it is not intended to relieve the 
driver of his or her responsibility for 
exercising due care and attention when 

Advice on ABS braking techniques

For optimum ABS performance, these 
instructions on braking techniques during 
ABS operation should be followed:
• Do not release brake pressure when 

the pulsating effect is felt. Maintain a 
constant pressure until the 
manoeuvre is completed.

• To familiarise yourself with the feel of 

the brake pedal during ABS braking, 
practise an emergency stop 
procedure, always making sure it is 
safe to do so. With the seat belts fitted 
to all occupants, drive the vehicle at 
32 km/h (20 mph) and brake sharply.

• ABS enables the driver to steer 

around obstacles during emergency 
braking. However, the consequences 
of turning sharply at high speed 
cannot be overcome by the ABS.

• Do not attempt to pump the brakes to 

avoid skidding, as this can interfere 
with the ABS operation. The ABS will 
not allow the wheels to skid under 
normal road conditions.

• The ABS will tend to keep the vehicle 

straight during braking. Braking 
distances may increase under certain 
road conditions. It is, therefore, 
necessary to plan and make turning 
manoeuvres as early as possible.


Stability Control


Stability Control


Dynamic Stability Control is operational 
whenever the engine is running, unless it 
has been switched off. If the system is 
operating, the warning indicator in the 
instrument pack will flash.

The DSC system controls the Anti-lock 
Braking System (ABS), traction control 
and yaw control of the vehicle.

Yaw control determines the vehicle’s 
direction relative to the driver’s inputs 
(sideslip and under/oversteer). It applies 
braking pressure to individual wheels if 
excessive variation is detected. This 
makes sure that the vehicle follows the 
driver’s intended direction of travel.

Traction control will intervene to prevent 
wheel spin, by automatically reducing the 
power output from the engine and 
applying braking to individual wheels.

This improves acceleration, particularly 
on surfaces with uneven friction; for 
example, one wheel on ice and the other 
on tarmac.

ABS helps to prevent the road wheels 
from locking and skidding during 
emergency braking. When the system is 
operating, the warning indicator in the 
instrument pack will flash.

The Dynamic Stability Control system can 
be switched OFF by pressing the switch 
on the center console. The warning 
indicator in the instrument pack will 
remain on and a message DSC OFF will 
be shown to indicate that the system has 
been switched OFF. If the switch is 
pressed again the system will switch ON.

Note: If cruise control is engaged it will 
automatically disengage if stability control 

A system malfunction is indicated by an 
amber warning indicator and the message 
DSC NOT AVAILABLE displayed in the 
message center.

The instrument pack warning indicator 
will also be lit.

It is safe to drive the vehicle, but the 
system may not activate under wheel spin 
or slide conditions. Report the fault to a 
Jaguar Dealer as soon as possible.



• The fact that the vehicle is fitted 

with Dynamic Stability Control must 
never allow the driver to be 
tempted into taking risks which 
could affect his or her safety, or 
that of other road users. In all cases 
it remains the driver’s responsibility 
to drive safely according to the 
prevailing conditions.

• It is recommended that when using 

snow chains, DSC should be 
switched OFF.

When DSC is switched ON and the 
system is activated, the transmission 
selects a shift pattern to suit traction 
control conditions.
