Gear Changing
When operating either the DB AR1 manual or Touchtronic transmission
systems, the following warnings are of particular importance:
WARNING: Do not skip one or more gears when downshifting, you could lose
control of the vehicle and injury could result.
WARNING: Shifting without correct operation of the clutch and throttle can
result in severe damage to the transmission and engine.
Gear Changing - Manual Transmission
The gear lever for the six speed manual transmission is spring biased to the
centre of the gate. Push to the left before selecting first or second gears and
to the right before selecting fifth or sixth gear.
Press fully to the right and forwards to overcome additional spring pressure
when selecting reverse gear. The reverse gear position has a solenoid lock
to prevent accidental engagement when driving forward.

Gear Changing - Touchtronic Transmission Control
The 'Touchtronic' transmission system can operate in Automatic, Sport and
Touchtronic modes. It is controlled using the special selector lever shown
below.

Gearshift Modes
Automatic Mode
When the gear selector lever is operated in the right half of
the selector gate ('A' showing in the instrument panel
display), the transmission is in Automatic mode.
The gearbox functions as a standard automatic five speed transmission. The
selector lever may be placed into the P, R, N or D positions. When D is
selected, gearshifts will be made automatically at points dependant on
vehicle speed, throttle position and engine load.
Sport Mode
The Sport mode can be selected by moving the gear selector
lever to the left from the 'D' position. The Sport warning lamp
on the instrument panel will illuminate on entering Sport
mode.
Sport mode may be cancelled by moving the selector lever back to the right
half of the selector gate to return to Auto mode. Sport mode is also cancelled
by selecting a gear in Touchtronic mode.
Touchtronic Mode
From the Sport position, Touchtronic mode is selected by any forward or
rearward movement of the selector lever or by pressing one of the steering
wheel gearshift buttons.
Any forward movement of the selector lever will engage the next higher
gear. Any rearward movement of the selector lever will engage the next
lower gear. The lever will return to the centre position after each movement.
In Touchtronic mode, all gearshifts are under driver control. The number of
the current gear appears in the digital selector display.

C - Driving
1-C-15 When at a standstill, Touchtronic mode is engaged by pushing the lever
forward or by pressing the '+' button on the steering wheel. The gearbox
controller will always initially select 2nd gear. If first gear is required, it may
be selected by pulling the lever rearwards or by pressing the - button on the
steering wheel.
When Touchtronic mode is engaged whilst driving, the transmission will
remain in the current gear. Gearshift control will revert from automatic to
manual control.
Touchtronic mode may be deselected whilst driving by moving the selector
lever to the right. The transmission will revert to Automatic mode and may
shift to a more appropriate gear.
Minimum Upshift Speeds
The transmission controller will only allow upshifts when vehicle speed is
above the following minimum limits:
Upshifts enabled 2nd to 3rd gear above 15 km/h (10 mph)
3rd to 4th gear above 35 km/h (22 mph)
4th to 5th gear above 52 km/h (32 mph)
During deceleration, if road speed falls below the minimum limit for each
gear, the transmission will automatically downshift to eliminate the possibility
of the engine stalling.
Gearshift Inhibit
In Touchtronic mode, any attempted gearshift which would cause the
engine speed to rise over 6,500 rpm, or fall below 1,300 rpm will be
prevented by the transmission controller.

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.

Clutch Fluid Reservoir
The clutch fluid reservoir (7) is fitted to the drivers side of the engine
bulkhead on manual transmission cars only.
Before removing the filler cap, clean it and the surrounding area to prevent
any ingress of dirt or foreign matter into the system. Top up the reservoir
using only the recommended fluid until the fluid level is at the maximum
mark. (see 'Specifications').
Caution: Take care that hydraulic fluid does not contact the paint work during the
topping up operation. Serious paint work damage can result. If a spillage does occur,
immediately flush the hydraulic fluid from the paint work with clean, fresh water and
then wipe with a clean damp cloth.

F - Owner Maintenance
1-F-27 The DB AR1 may then be winched onto a transporter or towed to a safe
location using a rope, provided that the following precautions are observed:
Transporting
If the vehicle is to be transported on a trailer or flat bed transporter, the
handbrake must be applied and the wheels chocked. Vehicles fitted with
Touchtronic transmission must have the gear selector lever moved to N or
D but NEVER in P. The parking lock may be damaged if the vehicle is
transported with the gear selector lever in P.
Four tie-down brackets are provided, two on each axle. These are NOT
suitable for solid bar towing.
Front Axle Tie-Down Rear Axle Tie Down
Vehicles with Defective Touchtronic Transmission
The vehicle must be carried on a transporter or towed with the rear wheels
clear of the ground (see suspended towing) or towed with the propeller shaft
disconnected at the final drive input flange. If the propeller shaft is
disconnected, it must be firmly secured away from the final drive flange.

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.
