JAGUAR XFR 2010 1.G Workshop Manual Winter Mode

To activate winter mode, press the winter mode button briefly (not less than 300 ms) to activate or de-activate the mode.

Winter Mode

To activate winter mode, press the winter mode button briefly (not less than 300 ms) to activate or de-activate the mode.

NOTE: Winter mode cannot be active at the same time as dynamic mode (Supercharged models only).

When active the winter mode icon and message appear in the instrument cluster message center to confirm the activation.
Dynamic Stability Control (DSC)

Press the DSC mode button briefly (not less than 300 ms) to switch between DSC and TracDSC. The instrument cluster
message center will display either 'DSC ON' or 'TRAC DSC' depending on which selection is made. When TracDSC is selected,
the DSC warning lamp in the instrument cluster is illuminated and the DSC button is illuminated.

DSC can be manually switched off by pressing the DSC mode button for more than 10 seconds. Confirmation is given by a
chime from the instrument cluster, 'DSC OFF' is displayed in the instrument cluster message center and the DSC warning lamp
in the instrument cluster is illuminated.

NOTE: DSC is operational at all times when the engine is running unless manually switched off.

Dynamic Mode (Supercharged models only)

To activate Dynamic mode, press the button briefly. The dynamic mode and DSC buttons are illuminated. 'Dynamic Mode
Confirmed' message is displayed in the instrument cluster message center and the DSC off warning lamp in the instrument
cluster is illuminated (due to automatic selection of TracDSC in Dynamic mode).

NOTE: Dynamic mode cannot be active at the same time as winter mode.

Once activated, TracDSC is automatically selected. In gearbox Sport mode, the driver has full control over the transmission
shift points and the TCM will not intervene to prevent engine overspeed (for example; upshifts are inhibited in gearbox sport mode when Dynamic mode is selected). In this setting, the gear indicator in the instrument cluster will turn amber at high
rev's to indicate an appropriate manual upshift point.

Inspection and Verification

CAUTION: Only serviceable items can be renewed or adjusted. Failure to follow this instruction may result in the warranty
of the component being rejected.

Certain driveline trouble symptoms are also common to the engine, transmission, wheel bearings, tires, and other parts of the
vehicle. For this reason, make sure that the cause of the trouble is in the driveline before adjusting, repairing, or installing any
new components. For additional information, refer to Workshop Manual section 100-04 Noise, Vibration and Harshness.
1. Verify the customer concern by carrying out a road test of the vehicle.

2. Visually inspect for obvious signs of mechanical damage and system integrity.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the concern is not visually evident, verify the symptom and refer to the Symptom Chart.

Identify the Condition

Gear Howl and Whine

Howling or whining of the ring gear and pinion is due to an incorrect gear pattern, gear damage or incorrect bearing preload.

Bearing Whine

Bearing whine is a high-pitched sound similar to a whistle. It is usually caused by worn/damaged pinion bearings, which are
operating at driveshaft speed. Bearing noise occurs at all driving speeds. This distinguishes it from gear whine which is speed
dependent.

As noted, pinion bearings make a high-pitched, whistling noise, usually at all speeds. If however there is only one pinion
bearing that is worn/damaged, the noise may vary in different driving phases.
A wheel bearing noise can be mistaken for a pinion bearing noise.

Chuckle

Chuckle that occurs on the coast driving phase is usually caused by excessive clearance between the differential gear hub and
the differential case bore. www.JagDocs.com

Clunk

Clunk is a metallic noise heard when the automatic transmission is engaged in REVERSE or DRIVE. The noise may also occur
when the throttle is applied or released. Clunk is caused by transmission calibration, backlash in the driveline or loose
suspension components and is felt or heard in the vicinity of the rear drive axle.

Bearing Rumble

Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a worn/damaged wheel bearing. The
lower pitch is because the wheel bearing turns at only about one-third of the driveshaft speed. Wheel bearing noise also may
be high-pitched, similar to gear noise, but will be evident in all four driving modes.
