General information
T he ope ra ti on of the Ele ctro nic Stabilization P rogr am ( ESP ) is
expanded for operation away from paved roads. In s ituations where
slip or a different ia l lock in g f unct io n is requ ired, t he ESP offroa d
mode can be activated~
page 256. Hill descent control is also avail­
able in the ESP offro ad mode, wh ich a utomatically bra kes the vehicle
and thereby keeps speed consta nt when d ifferent whee l speeds are
de te cted when descend ing a hill~
page 257. Your Audi also has
permanent all-wheel drive in add ition.
However , your Audi is not a pure offroad ve hicle.
It was not bui lt for
dr iv ing un der extreme cond it ions, e.g. for t rips that ar e in th e natur e
of an exped it io n.
Drive only on road s and offroad sections which match the design of
your vehicle and your abilities as a driver. Never take risks!
Before driving offroad
• Check the eng ine oi l level, tire pressure, coolant level, and the
fluid level in the w indshiel d wa sher rese rvoir.
• Stow luggage items and other objects in the luggage compart ­
me nt, and sec ure t hem agains t slid ing ar ound.
After driving offroad
• After tr ips offroad, remove a ny tw igs and other foreign objects
from the gr ill, the underbody an d the whee ls. Pay special attention to
fore ign obje cts (sto nes) wh ich have be come lodge d in the tire tr ead.
• Clean the body and the vehicle unde rside, and ins pect t he vehicle
for possib le dam age. •
Clean dirty w indows, headlamp lenses, rear lights, and lic ense
plates.
• Perform a bra ke check (pa rticul arly afte r travell ing t hrough
wate r).
& WARNING
• Drive especially attentively and plan ahead in difficult road
condit ions and when offroad. E xcessive speed or incorrect maneu­
vers can cau se injurie s and damage to the vehicle .
• Always adapt your speed and driving style to road, offroad,
traffic, and weather condition s. Drive especially slowl y offroad
when your view is restricted.
• Please be aware that in ESP offroad mode, particularly on a
smooth and slippery road, the wheels may have an increased
tendency to spin and the vehicle may break away - danger of skid­ ding!
• Stability i s limited in the ESP offroad mode.
Avoid dama ge to t he e nvir onment and respect nature .

Lights
T he headl ight settings shou ld be chec ked with the tr ailer attached
before driving off. Check to make sure both vehicle and trailer lights
are wo rking properly.
Safety chains
Be sure tra ile r safety cha ins are p roperly connected from the t rai ler
to the hitch on the vehicle. Leave enough slack in the chains to perm it
tu rning corners . When you install sa fe ty ch ains, ma ke sure they will
not drag on the road when you are driving.
T he chains should cross under the trai ler tongue to prevent it from
dropping in case of separation from the h itch .
0 Note
If you are goi ng to tow a trai ler , you must activate the trai ler opera­
tion mode =>
page 182, "Towing a trailer". •
Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip­
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart ­
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care­
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.
