Jacking and Wheel Changing
WARNINGS:
The front road wheels must be in the straight ahead position before removal. The
front tyre will catch on the wheel arch during removal if not in the "straight
ahead" position.
Check that the temporarily repaired tyre is inflated to the specified pressure.
Never exceed 50 km/h (30 mph) when a temporarily repaired wheel is fitted.
Ensure that no persons are in the vehicle before jacking commences.
Ensure that the handbrake (parking brake) is set and that the car is in 'Park' (Auto)
or 1st Gear (Manual).
Ensure that the vehicle is parked on firm and level ground to ensure a secure base
for the jack.
Do not run the engine while the car is on the jack and never let anyone work
under the car whilst it is on the jack.
Spare Wheel Access (where fitted)
On vehicles with the space saver spare
wheel, the spare wheel is stored in a
well in the boot floor.

Suspended Towing
Do NOT tow with sling-type equipment since damage to the bodywork may
result.
Take care when using 'spectacle frame' type towing equipment that the
towing device is well clear of the front or rear apron. Body damage may
occur if the vehicles pass over uneven road surfaces.
Adhere to Towing Regulations
In certain countries the registration number of the towing vehicle and an ON
TOW sign or warning triangle must be displayed in a prominent position at
the rear of the vehicle being towed.
Front Suspended Tow
Caution: To prevent body damage ensure an adequate clearance is
maintained between the car body and (1) the ground and (2) the 'spectacle
frame' of the towing vehicle while your car is being towed.
1. Remove the ignition key from the ignition.
2. Vehicles with manual transmission: Place the gear lever in neutral.
Vehicles with automatic transmission:
Disconnect the propeller shaft at the final drive input flange.
Ensure that the propeller shaft is firmly secured away from the final drive
input flange.

positioned under each front wheel as shown below.
Rear Suspended Tow
Caution: To prevent body damage ensure an adequate clearance is
maintained between the car body and (1) the ground and (2) the 'spectacle
frame' of the towing vehicle while your car is being towed.
1. Remove the ignition key from the ignition/steering lock.
2. Raise the vehicle using a 'spectacle frame' style lifting device where a
cradle is positioned under each rear wheel as indicated below.
Towing by Another Vehicle
WARNING: When the engine is stationary, there will be no power assistance to
the steering or brakes. Therefore be prepared for relatively heavy steering and
the need for greatly increased brake pedal pressure.
The vehicle may be towed short distances by another provided that a speed
of 48 km/h (30 mph) is not exceeded. Do not tow for more than 24km (15
miles). When being towed, the vehicles gear lever, or gear selector lever
(automatic transmission), must be in Neutral or position N with the ignition
key turned to position II to release the steering lock and to render the horn,
indicators and brake lights operational.

Electrics
Battery
The battery is located in the right-hand side of the boot. The battery is
maintenance free and should only require checking by your dealer during
regular vehicle services.
Battery charge level must be maintained by use of the battery conditioner
if the vehicle is not in frequent use.
Caution: The engine must never be run with the battery disconnected.
WARNING: The battery emits combustible gas (hydrogen) when charging. Avoid
sparks and short circuits by switching off the charger before connecting or
disconnecting the charger at the battery.
Battery posts, terminals and related accessories contain lead and lead compounds.
Wash hands after handling.

WARNINGS:
To help avoid personal injury, do not use open flame, smoke, or cause an electric
spark when checking the battery, as gas generated by the battery is flammable
and can explode. Always shield your eyes and avoid leaning over the battery.
Do not ingest battery acid or fumes. If battery acid is ingested, drink large
quantities of water or milk followed by milk of magnesia, beaten egg or vegetable
oil. Call for medical assistance immediately.
Do not let battery acid come into contact with skin, eyes, hair, fabric or painted
surfaces. A solution of warm soapy water and baking soda may help neutralise
acid.
Used batteries contain sulphuric acid, lead and other potentially hazardous
materials. Dispose of unwanted batteries in authorised waste disposal facilities.
DO NOT discard unwanted batteries in household waste.
Quiescent Battery Drain
Any power drain from a battery after the ignition is switched off is referred
to as 'quiescent battery drain'. Your DB AR1, in common with many modern,
high technology motor cars, contains electronic circuits and sub-systems
which must be left activated at all times. For example, the clock, security
systems and in-car entertainment system continue to drain battery power
even with the ignition switched off. This quiescent drain will discharge a fully
charged new battery in approximately 30 days unless recharged by normal
engine running or an independent battery charger.
It is therefore vital that, when leaving your car unused for extended
periods, you use the battery disconnect switch to minimise quiescent
drain and that you use the battery conditioner to maintain battery
charge level.

Battery Conditioner
The automatic battery conditioner supplied with DB AR1 is suitable for use
on all types of 12 volt lead acid batteries. The conditioner also allows
charging of maintenance free and 12V gel type batteries.
The conditioner has an inbuilt mains connector appropriate for the market
in which the vehicle is sold.
The conditioner output is 13.8V - 14.7V, up to 4.0A. It is designed for
conditioning of partially or fully charged batteries. It will not effectively
charge a completely discharged battery and is not a substitute for a
dedicated battery charger.
WARNINGS:
For indoor use only.
Disconnect the mains supply before making or breaking battery conditioner
connections.
Explosive gasses are given off by batteries during charging. Prevent flames and
sparks - No smoking.
Do not attempt to start the vehicle with the charger connected to the mains
supply.
The unit has an electronic controller which senses when the battery charge level
becomes low and commences charging.
When the battery charge level rises to 80%, a 2 hour timer starts. The unit
continues charging for a further 2 hours until the battery is 100% charged and
then reduces the charge voltage to 13.8 volts to maintain a small trickle charge
to keep the battery in a fully charged state. The conditioner may be left in this state
indefinitely.

Electrical Start from Another Vehicle
If your DB AR1 will not start due to a discharged battery, it may be started
by connecting the battery from another vehicle to the discharged battery.
Before the vehicle is started in this way, ensure that the donor vehicle has
a 12 volt battery and negative (-), black earth terminal to ensure that the
correct battery polarity is maintained.
WARNING: If the voltage or earth of the donor vehicle is different or not known,
do not attempt starting in the way described.
1. Position the vehicles so that the connecting cable will reach between
the batteries. Ensure that the vehicles do not touch each other.
2. To lessen the risk of an electrical short circuit, remove rings, metal
watch bands and any other jewellery. Wear eye protection when
working near the battery. Turn off all electrical motors and ancillaries
in both vehicles. Switch off all lights except those needed to protect the
vehicles or illuminate the work area. Switch off the ignition and apply
the handbrake.
3. Lift out the boot floor panels to gain access to the battery.
4. Connect the red (+) cable between the red (+) positive terminal of the
two batteries.
5. Connect the black (-) cable between the black (-) negative terminals of
the two batteries.
6. Start the donor vehicle engine and run at about 1500 - 2000 rpm.
7. Start the engine. Allow the engine to run for some minutes until the flat
battery is partially charged. Switch off both vehicles.
