Messages  
The following messages may appear, depending  
on the vehicle equipment:  
 / Parking brake: malfunction! Safely  
stop vehicle. See owner's manual  
Tips  
 / Parking brake: malfunction! Please  
release parking brake  
On steep inclines, especially when in trailer  
mode, the vehicle may roll backwards unin-  
tentionally when starting to drive. To reduce  
the risk of this happening, pull and hold the  
switch while pressing the accelerator  
pedal. If enough drive power has built up at  
the wheels and the vehicle does not roll  
backwards, then release the switch to start  
to drive.  
If one of these messages appears, there is a mal-  
function in the parking brake. If the message ap-  
pears while stationary, check if the parking brake  
is released and can be reset. If this is the case,  
turn the ignition off and back on.  
If the message stays on, if the parking brake can-  
not be released, or if the message appears while  
driving, do not continue driving. Secure the vehi-  
cle against rolling before exiting the vehicle  
ðpage 99. See an authorized Audi dealer or au-  
thorized Audi Service Facility for assistance.  
If you leave the vehicle when the “D” or “R”  
position is engaged, the parking brake will  
be set automatically.  
Noises when the parking brake is set and re-  
leased are normal and are not a cause for  
concern.  
Parking brake: malfunction! Please contact  
Service  
The parking brake goes through a self-test  
cycle at regular intervals when the vehicle is  
stopped. Any noises associated with this are  
normal.  
There is a malfunction in the parking brake. Drive  
to an authorized Audi dealer or authorized Audi  
Service Facility immediately to have the malfunc-  
tion corrected. Do not park the vehicle on inclines  
and secure it against rolling before exiting the  
vehicle ðpage 99.  
Emergency braking function  
Emergency braking should only be used in an  
emergency, if the standard brake pedal is mal-  
functioning or obstructed. When the emergency  
braking function is activated, the braking effect is  
similar to a heavy braking maneuver.  
/ Parking brake: warning! Vehicle posi-  
tion too steep  
The braking force may not be enough to secure  
the vehicle from rolling away. Park the vehicle in  
a place with less of an incline.  
Pull and hold the switch while driving.  
An audio warning signal will sound and emer-  
gency braking will begin.  
/ Parking brake: applied  
The parking brake is set. Press and hold the brake  
pedal to release the parking brake.  
If you press the accelerator pedal, emergency  
braking will be canceled.  
Take over!  
WARNING  
The vehicle cannot be held in place automatically.  
Press the brake pedal to secure the vehicle from  
rolling unintentionally.  
Heavy braking while driving through curves or  
in poor road or weather conditions can cause  
the vehicle to slide or the rear of the vehicle  
110  
Driving  
To reduce the risk of underbody damage, pay  
attention to the vehicle's ground clearance and  
drive across raised areas of the ground using  
the wheels on only one side of the vehicle, in-  
stead of allowing the center of the vehicle to  
pass over the raised areas.  
Special driving situations  
Driving uphill and downhill  
When driving uphill, downhill, or at high alti-  
tudes, note the following information:  
Drive slowly and carefully.  
To reduce the risk of becoming stuck, drive  
through sandy or swampy areas at a steady  
speed and without stopping, if possible.  
Do not try to turn around if you cannot safely  
drive on an incline or hill. Instead, drive in re-  
verse.  
If necessary, use the following functions:  
When driving down hills, you can activate the  
hill descent control if you press the brake pedal  
while driving in the “D” position. The automatic  
transmission will select a gear suitable for driv-  
ing down the hill and will attempt to maintain  
the speed at which the vehicle was traveling at  
the time the brake pedal was pressed. Press the  
brake pedal if necessary. The hill descent con-  
trol will turn off once the hill levels out or you  
press the accelerator pedal.

Limit ESC ðpage 117  
WARNING  
Only drive in terrain that is suitable for the ve-  
hicle and your driving ability.  
For the sake of the environment  
Utilize the engine braking effect when driving  
downhill by selecting the “S” driving program  
ðpage 101. This especially applies when tow-  
ing a trailer. This reduces the load on the  
brakes.  
Avoid actions that are damaging to the envi-  
ronment. Show respect for the natural envi-  
ronment and remain on marked routes.  
Tips  
Apply the brakes in intervals and do not press  
the brake pedal continuously.  
Clean your vehicle after driving offroad. Dirt  
and stones falling off your vehicle can affect  
other road users.  
Use the hill descent assist ðpage 112.  
WARNING  
Driving through water  
Only drive on inclines that your vehicle is de-  
signed to handle. Do not exceed the hill  
climbing ability of your vehicle. Your vehicle  
could tip or slide.  
If you must drive through water, follow these in-  
structions:  
Check the stability of the ground, the current,  
and the water depth. If the ground is unstable,  
there is a strong current, or there are waves,  
the water must only reach up to the lower edge  
of the body at the most.  
Do not drive at an angle on steep inclines  
and hills. If your vehicle is about to tip, you  
must immediately start steering in the di-  
rection of the downward slope to reduce the  
risk of an accident.  
Deactivate the Start/Stop system*.  
Drive carefully and no faster than at a walking  
pace to prevent the front of the vehicle from  
creating waves, because they could splash  
above the lower edge of the body. Oncoming  
vehicles could also create waves.  
Always be ready to brake when using the hill  
descent control function.  
Offroad driving  
Applies to: allroad  
Your vehicle is not an offroad vehicle. Note the  
following points when driving offroad:  
Do not stop the vehicle while in the water.  
Do not drive in reverse.  
Do not turn the engine off.  
Drive slowly and carefully.

WARNING  
WARNING  
After driving through water, press the brake  
pedal carefully to dry the brakes so that the  
full braking effect will be restored.  
Be ready to apply the brakes at all times  
when using the hill descent assist.  
Always adjust the speed to the visibility,  
weather, road, and traffic conditions. The  
system cannot replace the driver’s atten-  
tion.  
Note  
Vehicle components such as the engine, drive  
system, suspension, or electrical system can  
be severely damaged by driving through wa-  
ter.  
The system cannot maintain a constant vehi-  
cle speed in all situations, for example when  
on smooth or slippery ground. This can in-  
crease the risk of an accident.  
Tips  
Tips  
If possible, avoid driving through salt water  
because it increases the risk of corrosion. Use  
fresh water to clean any vehicle components  
that come into contact with salt water.  
If you select the Audi drive select* offroad  
mode, hill descent assist will turn on.  
Hill descent assist  
Applies to: vehicles with hill descent assist  
The button is located in the center console  
above the transmission selector. It lights up  
when the system is turned on.  
Hill descent assist can assist you when driving  
down hills by maintaining a constant vehicle  
speed by automatically braking all four wheels.  
You can adjust the speed using the accelerator  
and brake pedals. The regulation depends on the  
hill and the vehicle speed.  
Turning on: press .  
Turning off: press again.  
Active regulation  
Regulation begins shortly after you start driving  
and is possible at speeds up to approximately 19  
mph (30 km/h) and on hills that have an approxi-  
mately 6-60% grade. If these conditions are met,  
regulation will be activated and the  
light will turn on.  
indicator  
Ready mode  
If one of the requirements for active regulation is  
not met, the system will be in ready mode. The
