2015 AUDI Q3 differential

154 Intellig ent technolog y
Anti-slip r egulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive power to the o ther d rive
wheel or whee ls if the vehicle is equipped with
all-wheel drive* . This function is available up
to about 60 mph (100 km/h).
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to normal.
El ectron ic inte ra xle diff ere ntial lock */
se lec tive wheel t orque contr ol*
The electronic interaxle differential lock (front
wheel drive) or the select ive wheel torque
control (all-wheel drive) operates when driv­
ing through curves. The front wheel on the in·
side of the curve or both wheels on the inside
of the curve are braked select ively as needed .
This minimizes s lid ing in the front wheels a nd
allows for more p rec ise driving through
curves. The app licab le system may not acti­
vate when driving in wet or snowy conditions .
A WARNING
-ESC, ABS, ASR, EDL, the electronic inter­
axle differentia l lock* /selective whee l
torque control* and the hill descent as­
sist cannot overcome the laws of physics.
Th is is especially important on slippery
o r wet roads . If the systems begin acting to stabilize your vehicle, you should im­
mediately change your speed to match
the road and traffic conditions. Do not let the increased safety provided by
these systems tempt you to take r isks .
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and ser ious per­
sonal injur ies.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast , espec ially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL and the electronic inter­
axle d ifferential lock*/selective wheel
torque control* cannot prevent colli­
sions .
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow .
The drive wheels can spin even w ith
these assistance systems t hat cannot al­
ways he lp to reduce the risk of loss of ve­
hicle control.
(D Tips
- ABS and ASR only wo rk correct ly when
all four wheels are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working .
-If the ind icator light DJ or Ell (USA
mode ls)/ lCO)J there may be a malfunction~

164 Driving and en vironm ent
The amount of oil used is related to eng ine
load and speed.
I t is normal for the oil consumption of a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You must drive your vehicle about 3 ,000 miles
(5,000 kilometers) before you can properly
assess o il cons umption .
This a lso applies to fuel consumption and en­
g ine output .
0 Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your War ranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as imp roper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not a lter or remove any component of
the Emi ssion Contro l System unless ap­
proved
by the manufacturer.
- Do not a lter or remove any device, such
as heat shields, switches, ignition wires,
va lves, which are designed to protect
your vehicle's Emiss ion Control System
and other important veh icle compo­
nents .
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
• Try to avo id driving sho rt distances with a
cold eng ine.
The engine and catalytic converter have to reach their optimal
ope rating tempe ratu re to
reduce fuel con sumption and noxious emis­
sions effect ively.
Just after starting, a cold engine in a mid-size car on ly achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km) . After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2. 5 miles (4 km), the engine is at its proper operating tempera
­
ture and fuel economy has reached a normal
l evel. So you can see that you should avo id
short trips whenever possible.
T he
out sid e tempe rature is also critical in this
regard . Your car consumes more fue l in the
winter than in the s ummer.
Driving offroad
General information
When driving off road, the functions fo r the
electron ic stabiliza tion control ( ESC) are ex­
panded . The ESC-Offroad-Mode can be activat­
ed in driving situations in which a wheel lock
or a differential lock function is needed

Aft er d riving offroad
-After driving offroad, remove branches and
other debris from the radiator gri lle, under ­
body, and wheels. Look especially for objects
(stones) that have been caught in the tire
tread.
- Clean the body and the vehicle underbody
and inspect the vehicle for possible damag­
es.
- Clean off the dirty windows, headlights, tail
lights and the license plate .
- Pe rform a brake test (especially after driving
through water).
A WARNING
- Be especially aware and attent ive when
driving under difficult condit ions . Dam­
ages to the vehicle and injur ies may oc­
cur when driv ing at an excessively high
speed or with incor rect driving maneu­
vers.
- Always adjust you r speed and hand ling
to the roads, terrain, t raff ic and weather
