Lifting and Jacking
Safety
•Recommended procedures for lifting, jacking and
towing must be strictly ob served to ensure personal
safety.
• Always use a vehicle hoist, ramp or pit for working
beneath the vehicle in preference to jacking.
• Never rely on a jack to supp ort a car independently, use
axle stands or blocks carefu lly placed at jacking points
to provide rigid support.
• When working beneath a vehicle, chock wheels as well
as applying handbrake.
• Ensure vehicle is standing on firm, level ground before
jacking or lifting.
• Check lifting equipment has adequate capacity for load
being lifted and is in full working order.
Jacking Points
This vehicle jacking points are at positions shown.
May also be jacked on the front subframe front crossmember
Always use a jack with a rubber contact pad. Avoid use of
jacks with sharp contact pads which would damage floor
pan Always chock the opposite road wheels as well as
applying the handbrake when using a hydraulic jack.
To prevent body distortion, av oid single point or one side
jacking with the tunnel shear panel removed.
Lifting
Workshop Hoist
Use of a workshop hoist is recommended for all operations
where vehicles must be raised. Follow manufacturers
instructions. If using an adjustable arm type, ensure lifting
pads are correctly positioned at the four jacking points
before lifting.
Workshop Jack
To avoid any danger of bodywork damage when using a
hydraulic jack, the vehicle must only be lifted at the jacking
points.
Stands
When carrying out work (other than a wheel change) which
requires a wheel to be raised, a stand must be used, located
at the jacking point, to provide a secure support for the
vehicle.

Road Wheels and Tyres (04.04)
Suspension (04.00)
May 2007 Workshop Manual 4-4-3
Maintenance
Factory installed tyres and road wheels are designed to
operate satisfactory when inflated to the recommended
inflation pressures (Refer to ’Inspection and Verification’,
page 4-4-4). The recommended pressures apply to vehicle
loads up to and including the full-rated load capacity.
Correct tyre pressures and driving technique have an
important influence on tyre life. Heavy cornering,
excessively rapid acceleration and unnecessary sharp
braking increase tyre wear.
Replacement tyres should follow the recommended:
The use of any other size or type may seriously affect:
Wheels need to be renewed when:
Safety
Tyre Replacement and Wheel
Interchanging
When replacement of tyres is required it is preferable to
install a complete vehicle set. S hould either the front or rear
tyres only show excessive wear, new tyres must be installed
to replace worn ones. Under no circumstances interchange
tyres from side to side, front to re ar or vice versa as individual
tyre wear produces unique characteristics depending upon
their position. If the position is changed after wear has
occurred, the performance of the tyre will be adversely
affected.
New tyres must be balanced before installing to the vehicle.

WA R N I N G
A TYRE AND WHEEL MUST ALWAYS BE CORRECTLY MATCHED. WIDER OR NARROWER TYRES THAN
RECOMMENDED COULD CAUSE DANGER THROUGH
SUDDEN DEFLATION.
WA R N I N G
WHEN CHANGING A WHEEL, MAKE SURE THAT THE VEHICLE CANNOT MOVE. ALWAYS APPLY THE
PARKING BRAKE AND SELE CT THE TRANSMISSION
PARK POSITION (AUTOMATIC TRANSMISSION ONLY).
WA R N I N G
NEVER RUN THE ENGINE WITH ONE WHEEL OFF THE GROUND, FOR EXAMPLE, WHEN CHANGING THE
WHEEL. THE WHEEL RESTING ON THE GROUND MAY CAUSE THE VEHICLE TO MOVE.
WA R N I N G
ALWAYS TIGHTEN THE WHEEL NUTS TO
SPECIFICATION. TOO TIGHT MAY CAUSE DAMAGE,
TOO LOOSE MAY ALLOW TH E WHEEL TO BECOME
DETACHED.
WAR NI NG
DO NOT MIX DIFFERENT TY PES OF TYRES ON THE
SAME VEHICLE. HANDLING MAY BE SERIOUSLY AFFECTED RESULTING IN LOSS OF CONTROL.
WAR NI NG
USE ONLY WHEELS AND WHEEL NUTS SUPPLIED BY
ASTON MARTIN. AFTER MARKET WHEELS OR WHEEL
NUTS MAY NOT INSTALL OR FUNCTION CORRECTLY

Road Test
A tyre vibration diagnostic proc edure always begins with a road test. The road test and customer interview (if available)
will provide much of the information neede d to find the source of a vibration.
During the road test, drive the vehicle on a road that is smoot h and free of undulations. If vibration is apparent, note and
record the following:
• The speed at which the vibration occurs
• What type of vibration occurs in each speed range
• How the vibration is affected by changes in the following types of vibration-sensitivity:
Torque Sensitive - This means that the condition may be improved or made worse by accelerating, decelerating, coasting,
maintaining a steady vehicle speed or applying engine torque.
Vehicle Speed Sensitive - This means that the vibration always occurs at the same vehicle speed and is not affected by
engine torque, engine speed or the transmission gear selected.
Engine Speed Sensitive - This means that the vibration occurs at varyin g vehicle speeds when a different transmission
gear is selected. It may sometimes be isolated by increasing or decreasing engine speed with the transmission in NEUTRAL
or by stall testing with the transmission in gear. If the condition is engine speed sensitive, the cause is probably not relate d
to the tyres.
If the road test indicates that there is tyre whine, but no sh ake or vibration, the noise originates with the contact between
the tyre and the road surface.
A thumping noise usually means that the tyre has a flat or soft spot making a noise as they slap the roadway. Tyre whine
may be distinguished from axle noise. Tyre whine remains the same over a range of speeds.

difference between the ideal and actual response within a
tolerance band. This directly influences the forces on the
tires to generate a corrective yaw moment to reduce the side
forces of the tires where appropriate
System Overview
The DSC system embraces capabilities far beyond that of
ABS, or ABS and traction control combined, while relying on
the components of these systems. It also incorporates these
additional sensors for measur ing the vehicle’s motion and
brake system pressure:
Ya w r a t e s e n s o r - located centrally on the transmission
tunnel.
Lateral acceleration sensor - integrated with the yaw rate
sensor.
Steering angle sensor - located on the upper steering
column.
Pressure transducer - located on master cylinder.
The ABS / DSC module supports data exchange with other
vehicle electronic systems via the CAN network; the module
also enables diagnostic interrogation using WDS.
The following components register driver demand and the
ABS / DSC module processes their signals as a basis for
defining an ideal response:
PCM - position of accelerator pedal.
Brake master cylinder pressure transducer - driver’s
braking effort.
Steering angle sensor - position of steering wheel.
There are many supplementary parameters also included in
the processing calculations these include the coefficient of
friction and vehicle speed. The ABS / DSC module monitors
these factors based on signals transmitted by the sensors for:
• Wheel speed
• Lateral acceleration
• Brake pressure
• Yaw rate
Using these parameters, the function of the ABS / DSC
module is to determine the current vehicle status based on
the yaw-rate signal and the slip as estimated by the ABS /
DSC module. It then maintains the vehicle response within
a tolerance of the ‘normal’ behaviour, which is easily
controlled by the driver.
In order to generate the desired yaw behaviour the ABS /
DSC module controls the selected wheels using the ABS
hydraulic system and engine control system. In the event of
engine intervention, the ABS / DSC module calculates the
torque which should be supplied by the engine to the
wheels, and relays this request signal to the PCM which
implements the torque request.
The PCM receives signals from the DSC system via the CAN
bus and reduces engine torque as follows:
• The throttle is positioned to provide the requested engine target torque. • During the transient phase of torque reduction caused by
mechanical and combustion delays, other alternative
torque reduction methods are used to provide a quicker
response.
• The ignition is retarded and / or the fuel is cut-off at the injectors at selected cylinders.
• Ignition and fuelling are reinstated when the engine torque reaches the requested value
Operation Summary
• DSC is switched ‘ON’ when the engine is started
• When the system is operating , the DSC light in the instrument cluster will flash, at the rate of twice a second
• DSC can be switched ‘OFF / ON’ by pressing the DSC switch
• The DSC light in the instru ment cluster will illuminate
continuously when the system is switched ‘Off’.
• ‘DSC OFF’ will be displayed in the message centre right to indicate the system has been switched ‘OFF’
• A malfunction in the traction control system will be indicated to the driver by the following:
• The DSC light in the instru ment cluster will illuminate
continuously
• The message ‘DSC NOT AVAILABLE’ will be displayed in the message centre right
• If vehicle speed control is engaged it will automatically disengage when traction control is operating .
Traction Control
Traction control is a function of DSC, and is operated in
association with DSC. Traction control prevents excessive
wheel-spin at standing starts, or during acceleration. Wheel-
spin is usually caused by ex cessive use of the accelerator
pedal, or slippery, loose or bumpy road surfaces. To prevent
excessive wheel-spin and mainta in vehicle stability such
situations are overcome by the intervention of the traction
control system by:
• Braking the driven-wheel when it starts to slip
• And / or adapting the engine torque to a level corresponding to the traction available on the road
surface.
Functional Description
Traction control uses the ABS electronic and mechanical /
hydraulic hardware with additional valves to control the
braking pressure at the calipe rs. An engine interface also
enables the engine to respond to torque reduction requests
from the traction control. As with ABS, the signals from the
wheel-speed sensors are supplied to the ABS module, where
they are used to calculate the wheel-slip of the individual
wheels. Traction control intervention is initiated if the slip at
one of the wheels is excessive.
