The  hazard warning

if the  key isn’t  in. 
Press the  button to  make your front  and rear turn signal 
lamps flash on and 
off. Press the button again to turn

3. Press the  top  of  the UP/DN switch until the HUD 
image  stops moving.  Then  press the  bottom  of the 
switch until  the  image is  as low as possible  but 
in  full  view. 
4. Move the DIM thumbwheel down ur;til the HUD 
image  is no  brighter  than  necessary.  To turn the 
HUD off, move  the DIM thumbwheel  all  the 
way  down. 
If the  sun  comes  out,  it becomes  cloudy, or if you turn 
on  your  headlamps,  you  may  need 
to adjust the 
HUD brightness  again.  The HUD will automatically  dim 
when  the  headlamps  change  from the 
DRL mode to 
full  intensity.  Polarized sunglasses could  make the 
HUD 
image  harder to  see. 
Push the 
ENG/MET button 
on  the trip calculator, 
located  above the audio 
controls  on the trip 
computer  (if  equipped) on 
the instrument panel, 
to switch the 
HUD display 
between  English to 
metric. 
Care of the HUD 
Clean  the inside  of the windshield  as needed  to remove 
any  dirt or film that  reduces the sharpness  or clarity 
of  the 
HUD image. 
To clean  the HUD, spray  household  glass cleaner  on a 
soft, clean cloth.  Wipe the 
HUD lens gently,  then dry 
it. Do not spray cleaner directly  on the  lens  because  the 
cleaner  could leak into the  unit. 
If your vehicle is not  equipped with the trip calculator, 
you  cannot  change  the  display.

Anti-Lock  Brake  System  Warning Light 
if your vehicle  has the 
optional anti-lock brake 
system,  this  light will  come 
on  when  your engine  is 
started  and  may  stay on 
for  several seconds. 
That’s normal. 
If the  anti-lock brake  system warning light stays  on 
longer  than normal  after you’ve started your engine, turn 
the  ignition 
off. If the light  comes  on  and  stays on 
while  you’re driving,  stop as soon  as possible  and  turn 
the  ignition 
off. Then  start  the engine again  to reset 
the  system. 
If the  light still stays  on, or comes  on  again 
while  you’re  driving,  your  vehicle needs service. 
If 
the light is  on  and  the regular brake  system  warning 
light  isn’t on, you  still have  brakes, but  you don’t  have 
anti-lock  brakes. 
The  anti-lock brake  system warning light should  come 
on  briefly  when  you  turn  the  ignition key to 
RUN. This  is 
normal. 
If the  light  doesn’t  come  on  then, have it 
fixed 
so it will  be  ready  to warn  you if there  is a problem. 
Traction  Control System (TCS) 
Warning  Light 
TCS 
OFF 
If  your  vehicle is 
equipped  with the 3800 
supercharged V6 engine, 
the  traction control 
system  warning light 
may  come  on  for  the 
following reasons: 
If  you  turn the system off by pressing  the  TCS 
button located  on the  far right side  of the  trip 
computer,  the warning light will  come on and  stay 
on.  To  turn  the  system  back  on, press the  button 
again. The  warning light should  go 
off. See Traction 
Control  System  (TCS) on page 
4-10 for  more 
information. 
@ If there’s  a brake  system  problem  that is specifically 
related  to traction control, the traction control 
system  will turn 
off and the warning light will  come 
on.  If  your  brakes begin to overheat,  the traction 
control  system  will turn 
off and  the warning  light will 
come  on until your brakes cool  down. 
If the traction control  system warning light  comes on 
and  stays  on for  an  extended  period of time  when  the 
system 
is turned  on, your vehicle  needs service.

Enhanced Traction System Warning 
Light 
TRAC 
OFF 
If  your  vehicle  is equipped 
with  a 
31 00 V6 or 3800 V6 
engine and  the optional 
ABS  brake  system,  the 
Enhanced  Traction System 
warning  light may  come  on 
for the following reasons: 
e 
e 
e 
If you  turn the  system off  by pressing the  TRAC 
button  on the far right side  of the  Driver Information 
Center  or  trip computer  (if  equipped), the warning 
light will  come on and  stay on.  To turn the  system 
back  on, press  the button again. The warning light 
should  go 
off. See Enhanced Traction System (ETS) 
on page 4-1 1 for more  information. 
If the Enhanced  Traction System warning light 
comes  on  and stays on  for  an  extended  period of 
time while the  system is turned  on,  your vehicle 
needs  service. Adjust your driving accordingly. 
If the traction control  system is affected  by an 
engine-related problem, the  system will turn  off and 
the warning light will  come on. 
When  this warning light  is on,  the  system  will not limit 
wheel  spin.  Adjust your driving accordingly. 
Low Traction Light 
LOW 
TRAC 
If  your  vehicle  has  the 
Enhanced  Traction 
System  or  the  Traction 
Control  System,  this  light 
will  also  come  on  while 
the  system  is limiting 
wheel  spin. 
You may  feel or hear  the  system  working,  but this  is 
normal. Slippery road conditions  may  exist 
if the 
low  traction  light  comes on, 
so adjust your  driving 
accordingly.  The light  will stay  on  for  a  few  seconds  after 
the  Enhanced  Traction System  or  the  Traction Control 
System  stops limiting  wheel  spin.  See  Enhanced 
Traction System 
(ETS) on  page 4-1 1 or  Traction  Control 
System (TCS) on  page 
4- 10. 
The  low traction light  also  comes  on briefly when you 
turn the ignition key  to RUN. If the  light  doesn’t  come on 
then,  have  it fixed so it will  be there  to tell  you  when 
the  Traction Control  System  or  Enhanced  Traction 
System  is active.
