With the introduction of the Audi Q5, Audi is extending its model range to include a compact SUV thatstandards in its class. In addition to the Audi Q7 and the Audi A6 allroad quattro, Audi is now introducinfor the off-road segment.

The Audi Q5 will be manufactured at the Ingolstadt facility, this being a logical choice of location becauis based on components used in the Audi A4 08.

The new Audi Q5 combines the dynamism of a sports saloon with highly variable interior and versatile leisure-time and family use. Strong and efcient engines, Quattro permanent all-wheel drive and agile ruhave been brought together to create a superior technology package for both on and off road driving. Hias the innovative S tronic seven-speed dual-clutch gearbox and the Audi drive select driving dynamics sevidence that substantiates the Q5's claim to Vorsprung durch Technik. The sportiest SUV in its class, it multifunctional and comfortable.

Body

The body of the Audi Q5

The steel body of the Audi Q5 with its function andweight optimised design is yet another exampleof advanced body design by Audi. To meet thedemands on the Audi Q5, the various bodycomponents have been made using steel materialsdesigned to optimally absorb the structural anddynamic forces to which the vehicle can besubjected both in day-to-day use and in the event

of a collision.

For this reason, only 30.8 % of the components inthe Audi Q5 are manufactured from regular deep-drawn steel. High and advanced high strengthsteels account for nearly 60 % of all materials used -a signicant proportion.Parts manufactured from ultra-high-strength, die-quenched steels account for over 9 %, which islikewise a relatively large proportion.However, when manufacturing parts from thismaterial, the zinc coating otherwise normallyapplied to Audi body panels would evaporateduring the heat shaping process, because zinc has aboiling point of 907 C and the pr ocess temperatureis higher than that.

For this reason, the sheemaking die-quenched bowith aluminium, which protecting the steel surfWhereas steel was also tthe doors, the engine hoof aluminium.

Repair concepts

The increased use of ultra-high-strength steelsnecessitates the use of body repair methodsadapted specially to suit the properties of thematerials. High heat input welding will ir reversiblycompromise the strength and structure of thecomponent due to microstructural changes in thematerial.A body structure thus welded cannot, therefore,

reliably meet the requirements.It is important to apply a very high contact pressureand a precision controlled electrical current duringspot welding work on ultra-high-strength die-quenched steels.

Occupant protection

Occupant protection system in the Audi Q5

On the following pages you will be provided with an overview of the occupant protection systemAudi Q5. For further information about the restraint systems in the Audi Q5, please refer to SelfProgrammes 392 Audi A5 and 409 Audi A4 08. The diagrams and illustrations shown in the cha"Occupant protection" are intended to aid understanding.

The occupant protection system in the Audi Q5 consists of the following components and system

Airbag control unit Driver airbag, adaptive Front passenger airbag, adaptive Front side airbags Head airbags Front airbag crash sensors (upfront sensors) Crash sensors for side impact detection in the doors Crash sensors for side impact detection on the C posts Front belt tensioners with adjustable belt force limiters

Battery disconnect safety device Seat belt reminder for driver and front passenger Seat belt switch, driver and front passenger side Seat occupancy sensor in the front passenger seat Driver and front passenger seat position sensors

The vehicle can also be equipped with rear side airbags and/or a key switch for deactivating the fpassenger airbag, complete with a warning lamp.

On account of the different requirements and statutory regulations of the various markets on vehmanufacturers, equipment specications - par ticularly for the US market - can vary.

As long as igniter 2 is not activated, the supplemen-tary vent holes in the distributor housing are keptsealed by the control ring.

The gas from the gas generator ows out throughthe upper ports in the distributor housing anddirectly into the airbag. A retaining clip holds thecontrol ring in the rest position. This preventsunwanted rotation of the control ring.

The airbag control unit J234 decides when toactivate igniter 2 N250 according to the force of

the impact and the driver's seating position.

When igniter 2 is ignited, the developing gaspressure displaces a pin, which in turn rotates thecontrol ring. The supplementary vent holes in thedistributor housing are opened.The residual gas from the gas generator can now

ESP

A new ESP generation by Bosch with the designa-tion ESP Plus is used in the Audi Q5. Comparedto the ESP 8.1, the ESP Plus system has beenoptimised in design and functioning.The electric pump drive motor has been uprated,thus optimising its dynamic control behaviour.

The basic functions of EEBC etc. are identical toIn addition, there are neexplained below.

ESP Offroad Mode

The ESP Offroad Mode has been developed specically for use in rough terrain. When ESP Offractive, the ESP control processes are adapted to the offroad conditions. ESP control processes armuch later, thereby allowing drift movements about the vehicle's vertical axis and partial wheel This ensures that optimum traction is achieved on soft or loose sur faces.

ESP control

Automatic offroad detection

In 2009, for the rst time, the existing ESP functionswill be extended to include an automatic offroadrecognition feature. This feature will be imple-mented by evaluating the wheel oscillation as

indicated by the wheel speed signals.

When offroad conditions are detected, the controlcharacteristics of the ABS, TCS and EDL systems aremodied accordingly. Higher slip values are allowedat the wheels.When braking, for example, partial locking of thewheels causes wedges to form in front of thewheels due to the displacement of loose sur face

material. These wedges increase motion resistance,i.e. they provide additional braking. If the driver hasactivated the ESP Offroad Mode using the ESP OFFbutton, offroad conditions are detected even morequickly than by automatic detection.

Switchover of the rear lights

Symmetrical switchover on opening the tailgate

When the tailgate is opened, the brake/tail lightsand the turn signals are switched over from themain rear lights to the auxiliary rear lights. Thelamps in the main rear lights are then deactivated.When the tailgate is closed again, the systemswitches back to the main rear lights.The auxiliary rear lights are then deactivated again.

Asymmetric switchover in the event of lamp failure

In the event of failure of a turn signal/brake light ortail light function, the system switches over asym-metrically to the lamp in the auxiliary rear light,i.e. only the faulty side is switched over. If thisoccurs, a fault message is indicated via the dashpanel insert.

If the system switches over to the auxiliary rearlights because the main rear lights have failed, noattempt is made to switch on the main rear lightsagain until the next terminal 15 cycle begins.

Aerial diagnostics

All radio aerials in the Audi Q5 have full self-diagnostic capability. Now open circuits in the aerinot only be detected between the tuner and the amplier. In fact, the new method enables the aerto be tested through the amplier up to the aerial. This has the advantage that a fault is stored in tmemory if, for example, the connection to the rear window is broken.This means that there is no need for a laborious analysis of reception strength in order to trace a complaint.

Heated cupholder Z105

The cupholder Z105 is heatable and coolable.It is installed in the centre console between the MMIcontrol panel and the armrest.The Peltier effect is used to control the temperatureof the cupholder. Peltier elements consist of amultiple identical, square-shaped p-n type semi-conductor junctions connected in series.This plate-shaped Peltier conguration is sand-wiched on both sides, electrically and mechanically,

by ceramic plates. When a direct current is applied,one side of the plate heats up while the other sidecools down. The heating and cooling sides areinverted by reversing the direction of the electricalcurrent.
