Description 
A pp lies to  veh icles : w ith  night v isio n ass ist 
The night  vision assist  can detect,  highlight  and, 
if  necessary,  warn  about  pedestrians  and  large 
wild animals. 
Night  vision  assistant  with  pedestr ian and wild 
animal  detection  assists you  in darkness  by using 
an infrared  camera to  monitor  the  area in front  of 
your  vehicle,  within the limits  of  the  system. 
It 
can display  objects  up to  approximately 
1000  feet  (300  meters)  away. The  heat  image  de
tected  by the  camera  is shown  in  the  instrument 
cluster  display. Warm  areas appear  lighter  and 
cold  areas appear  darker.

that  are within  the  detect ion  range  between  ap
proximately  32  feet  (10  meters)  and 295  feet 
(90  meters)  in  front of the  vehicle.  When  it is

If there  are  pedestrians  or wild  animals  in an  area 
in front  of your  vehicle  that  is classified  as  criti
cal,  the system  will  direct  your  attention  to this: 
- Pedestrians  or wi ld  animals  are  highlighted  in 
red  and  the  corresponding  symbol. or. 
turns  on 
¢fig.  112. 
-There  is also  a tone. 
The  area  classified  as  cr itical  is based  on  the  vehi
cle  speed  and  the  steering  w heel  angle.  Pedes
tr ian  and  wild  animal  warning  encourages  you  to 
pay more  attention. 
I f the  nigh t vision  assist  image  is replaced  by an

Ma rking  light* 
To direct  the  driver's  attention  to  a  pedestr ian, 
the  headlights  can  flash  on  the  pedestr ian  th ree 
times  in a  row when  the re  is  a  pedes trian  warn

This happens  at  speeds  above  approximate ly 
35  mph  (60  km/h)  when  you  are  traveling  ou t
side  of we ll-lit  areas  and  when  flashing  the  head
lights  will  not  create  glare  for  a vehicle  detected

The following  situat ions  may  affect  the  function 
of  the  night  vision  assist  system: 
- Poor visibility  such  as  snow , rain,  fog  or  heavy 
spray 
- Dirty lens  on  the  night  vision  assist  camera 
Make sure  the  night  vision  ass ist  camera

any other  obstructions  because  that  can  affect 
the  camera  function . For information  on  clean

page  205. 
Pedestria n and  wild  anima l detect ion  depends  on 
the  difference  in temperature  between  the  per son/wild  animal  and  the  background  area.  Pedes 
trians/wild  anima ls  may  not  be  detected  if the 
difference  is too  small.  Pedestrian  and  wild  ani
mal  mark ing  and  the  marker  light*  are  deactivat
ed  at  temperatures  above  approximately  77  °F 
(25  °C) and  when  it  is light  outside . When  the

Automatic  transmission S  tronic,  tiptronic 
Introduction 
The automat ic transm iss ion  is  controlled  elec
tronically.  The  transmission  upshifts or down
shifts  automatically  depending  on  which  drive 
program  is selected. 
When  a 
moderate  driving  style is  used,  the 
transmission  selects  the  most  econom ical  driving 
mode.  The transmiss ion upshifts  at a lower  RPM 
and  downshifts  at a  higher  RPM  to improve  fuel 
efficiency. 
The  transmission  switches  to  a  sporty  mode  after  a  kick-down  or when  the  driver  uses  a 
sporty  driv
ing  style 
cha racterized  by quick  accelerator pedal 
movements,  heavy  acceleration,  frequent 
changes  in speed  and  traveling  at  the  maximum 
speed. 
If  desired,  the  driver  can also  select  the  gears 
manually (tiptronic  mode) ¢ page  111. 
Various  automat ic  tr ansm issions  may  be  instal
led,  depending  on  the  model: 
S tronic  transmission 
The S tronic  is a  dual -clutch  transmission . Power 
is  transferred  using  two  clutches  that  work  inde
pendently  from  one  another.  They replace  the 
torque  converter  used  in conventional  automat ic 
transmissions  and  a llow  the  vehicle  to  accelerate 
without  a  noticeable  interruption  in traction. 
tiptronic  transmission 
In  the  tiptronic  transmission,  power  is transfer
r ed  by a  torque converter.

A WARNING 
- The  vehicle  can  also  roll  when  the  engine  is 
stopped. 
- Unintended  vehicle  movement  can  cause  se
rious  injury . 
- Never  leave  your  vehicle  with  the  engine 
running  while  in gear.  If  you  must  leave  your 
vehicle  when  the  engine is running,  activate 
the  park ing brake  and move  the  selector  lev

- Power  is still  transmitted  to  the  wheels 
when  the  engine is running  at  idle.  To pre
vent  the vehicle  from "creep ing",  you  must 
keep  yo ur foot  on  the  brake when  the engine 
is running  and  the  se lector  lever  is  in  D/S or 
R  or  "tiptronic"  mode  is selected. 
- Do not  press  the accelerator  pedal  when 
changing  the  se lector  lever  position while 
the  vehicle  is stationary  and  the  engine  is 
running  . 
- Never  shift into  R  or P while  driving. 
- Before  driving  down  a steep  slope,  reduce 
your  speed  and shift  into  a  lower  gear with 
"ti  ptronic".

Automatic  transmission 
-Do not  ride  the  brakes  or  press  the  brake 
pedal  too  often  or  too  long when  driving 
down  a  hill.  Constant  braking  causes  the 
brakes  to  overheat  and  substantially  re
duces  braking  performance,  increases brak
ing  distance  or  causes  complete  failure  of 
the  brake  system . 
- To  prevent  the  vehicle  from  rolling  back 
when  stopping  on  inclines,  always  hold  it  in 
place  with  the  brake  pedal  or  parking  brake. 
- Never  hold  the  vehicle  on  an  incline with  a 
slipping  clutch.  The  clutch opens automati
cally  when  it becomes  too hot  from  the 
overload . An  indicator  lamp

@ Note 
- When  stopping  on  an  incline,  do  not  try  to 
hold  the  vehicle  in place  by pressing  the  ac
celerator  pedal  while  a  driving  gear  is se lected . This  can  cause  the  transmission  to 
overheat  and  can  damage  it . Activate  the

prevent  the  vehicle  from  rolling. 
- Allowing  the  vehicle  to roll  when  the engine 
is  stopped  and  the  selector  lever  is  in  N will 
damage  the transmission  because  it is not 
lubricated  under  those  circumstances. 
@ Tips 
For  safety  reasons,  the parking  brake is re
leased  automatically  only  when  the driver's 
safety  belt  is engaged  in the  buckle.
