Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel rang e and driving tim e.
Fi g. 15 Trip computer display: Average fuel mileage
The fo llow ing informa tion is cont in uously
eva luate d by the trip compu ter and can be dis
p layed sequent ia lly in the instrument cl uster
d isp lay:
Fuel range
The estim ated cruising r ange in miles (k m)
appears in the display . This te lls you how far
your veh icle w ill be able to t ravel on the cur
rent tank of fue l and with the same dr iving
style. The display changes in increments of 6
m iles (10 km).
Average fuel mileage
The ave rage fue l economy in MPG (l/ 100 km)
since you last clea red the memory appears i n
this display. Yo u can use th is disp lay to adjust
your driving technique to achieve a desired
mileage.
Current fuel mileage
The instantaneo us fue l cons umption in miles
pe r gallo n (l/ 100 km) is shown in this d isp lay .
You can use this display to adj ust your dr iving
techniq ue to ach ieve a des ired mileage.
Fu el consumption is reca lcula ted at interva ls
of 33 yards (30 mete rs) . This display switches
to ga llons/ho ur (lite rs/hou r) when the vehicle
is not mov ing.

Memories
The trip comput er is equipped with two fully
automatic memories as well as an efficiency

208 Driving and environment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.,. Shut the engine off when you are not driving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop -System* . It is ef
fic ient to sw itch
off the eng ine in vehicles
without the Start-Stop-System* when stopped
at railroad crossings and long red lights. Turn
ing the eng ine
off for just 30-40 seconds
saves more fuel than is burned by sta rting the
engine again .
It takes a long time for the engine to wa rm up
fu lly when it is running at idle. However , wear
and nox ious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af
ter starting. If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could resu lt in over
heat ing or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
.,. Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
consumption. Check
your oil each time you fill your tank.
The amount of oi l used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven .
You must drive your veh icle about 3,000 mi les
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fuel consumption and en
gine output .
(0 Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec
ommendations in your Warranty
& Ma in
tenance booklet. Lack of proper ma inte
nance as well as improper use of the ve
hicle will impair the function of the
em iss ion control system and could lead
t o damage.
- Do not alter or remove any component of
the Emission Control System unless ap
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shie lds , switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo
nents.
' Fewer short trips
Fuel consumption will always be relatively
high on short trips.
... Try to avoid driving sho rt distances w it h a
cold engine .
T he eng ine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and nox ious emis
sions effectively.
Jus t after starting, a cold engine in a mid-s ize
car only achieves a fuel economy of 6-8 mi les
per gallon (30 -40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg .,..
