Fig. 89 Roof: mount ing points for the roof rack
If luggage or cargo is to be ca rr ied on the roof,
you m ust observe the fo llow ing:
- On ly a specially designed roof rack may be used
on you r vehicle. These roof racks are the bas is
for a comple te roof rack system. Additional at­
t achments/ca rrier systems are necessary to
transpo rt luggage and spo rts equipment. We
recommend roof racks and attachments from
the Audi Genuine Accessories program.
- When installing the roo f rack, make sure that it
is mounted only at the designated points on
the roof
c::> fig. 88 or c::> fig. 89.
- The max imum permissib le roof load for your
vehicle is 200 lbs (90 kg). The roof load is the
total of the weight of the roof rack, the attach­
ments and the cargo you are carrying. However,
please note the permissib le load of the carrier
system being used, the permissible axle loads
and the permissible total vehicle weight
c::> page 3 79.
.&_ WARNING
- Follow the install ation instru ct ions prov ided
w ith the roof rack system.
If you do not se­
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and ca use an accident.
- The risk of an accident increases when using
a roof rack system, because it changes the
driving characterist ics by shifting the center
of grav ity and/or the increasing the surface
area exposed to wind. Adapt your driving
and speed to the current cond itions.

Driving
Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not drive at speeds
that will exceed 2/3 of the maximum perm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid full acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
h igher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine. This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (RPM) .
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
(D Note
When driving on poor roads, by curbs and on
steep ramps, make su re that low-hang ing
components such as the spoi ler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads:
-The water must not be any higher than the bot­
tom of the vehicle body .
80
-Do not drive faster than walking speed .
A WARNING
After driving through water or mud, the effec­
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes and restore the full braking ef­
fect .
{CT) Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys-
tem can be severely damaged by driving
through water .
-Always switch the Start/Stop system* off
when driving through water <=:>page
85.
@ Tips
-Determine the depth before driving through
water.
-Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water .
'
-Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safe ly .
-Avoid driving through salt water, because
this can cause corrosion .
Economical and environmentally -friendly
dr iving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­ proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time .
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a gear
