Additional Automatic Gearbox Functions
Kickdown (Automatic and Sport Modes Only)
If maximum power is demanded from the engine by opening the throttle to
more than about 95%, the kickdown function is automatically actuated.
With kickdown in operation, the gearbox may shift to the next lower gear
and further upshifts will occur at much higher engine speeds than when
using modest throttle openings. This mode is useful to achieve maximum
acceleration when, for example, overtaking another vehicle.
Torque Converter Lock-up
When driving in 3rd, 4th or 5th gears, a further change takes place within
the transmission. The torque convertor, transmitting power from engine to
transmission, will lock to improve the transmission efficiency. This is a
completely automatic function of the transmission system and will occur at
predetermined speeds.

5. Using the handwheel (A) on the jack screwshaft, raise the jack until the
jack top plate (B) fits to the jacking point stud under the sill at the affected
wheel. Ensure that the jack baseplate is squarely seated on solid ground.
Note: In the following step, the jack handle extension (D) must be used to prevent
damage to the vehicle paintwork as the jack handle (C) is rotated.
6. Ensure the safety of any persons in the vicinity and the security of the
wheel chock. Raise the vehicle as necessary using the jack ratchet handle
(C) and extension (D) to lift the deflated wheel clear of the ground.
Remove the wheel nuts and remove the deflated wheel.
7. Mount the spare wheel on the hub. Reverse the jack ratchet handle on
the extension and partially tighten the wheel nuts.
8. Lower the vehicle to the ground. Tighten the wheel nuts alternately.
Remove the wheel chock.
9. Repack the tools into their location in the boot. Place the defective wheel
into the bag provided and place on the rear seats.
10. When the spare wheel is correctly fitted and secured, drive conservatively
(80 km/h (50 mph) maximum) and have the wheel nuts torque tightened
to 88-102 Nm (65-75 lbs/ft) at the earliest opportunity.
WARNINGS:
Follow the wheel label warnings. Failure to comply can be dangerous. Drive
cautiously and refit a serviceable standard wheel and tyre as soon as possible.
Never fit more than one temporary spare wheel at a time.
Check that the temporary spare tyre is inflated to the specified pressure.
Never exceed 80 km/h (50 mph) when the spare wheel is fitted.

Storing the Car - Recommendations
Note: These recommendations apply to new and pre-owned cars either in
Dealer or customer ownership.
When ever the car is not in use always cover the car with it's fabric cover.
If the vehicle is not to be used for periods up to six months it should be stored
in a dry, well ventilated building.
Drive the car for a sufficient distance to warm the oil in the engine, torque
convertor, transmission and final drive unit; this ensures complete lubrication
of the internal components.
Check the engine coolant level. Top up if necessary with the correct
antifreeze/water solution.
In order to take the weight off the tyres, raise the car with a jack and place
supports under the front and rear suspension.
If the vehicle is not raised from the ground, increase the tyre pressures to 3.4
bar 340 kpa 50 psi. Cover the tyres to exclude any light. Rotate the wheels
1/4 turn every month to avoid tyre flat spots.
The battery should be removed and cleaned. Fully charge the battery on a
trickle charger and recharge once a month.
Once a month
Reconnect the battery and ventilate the storage area. Start and run the
engine until fully warmed up. Check that there are no fluid leaks. Check
and correct the tyre pressures if necessary.
Run the Air Conditioning system to keep the internal parts of the Air
Conditioning system lubricated.
