Turn Signal  and  Lane  Change  Indicator 
The turn  signal  has two upward (for right) and two 
downward  (for left)  positions.  These  positions  allow you 
to signal  a turn  or  a  lane  change. 
To signal  a  turn,  move the  lever all the  way up or down. 
When  the turn is  finished,  the  lever  will return 
automatically. 
An arrow on 
the instrument 
panel will flash  in the 
direction 
of the turn or 
lane  change. 
To signal  a  lane  change,  just  raise  or  lower the lever 
until the arrow starts  to  flash. Hold it there until you 
complete your lane  change.  The lever will return 
by 
itself when  you  release it. 
If the arrow flashes  faster  than normal as you  signal a 
turn  or a lane  change,  a  signal  bulb  may be burned  out 
and  other  drivers  won’t see your turn  signal. 
If  a  bulb  is  burned out,  replace  it  to  help  avoid  an 
accident.  If the arrows don’t  go on at all when 
you 
signal  a  turn,  check for burned-out  bulbs and then check 
the  fuse  (see  “Fuses and  Circuit Breakers”  in the  Index). 
A chime will sound  if 
you leave your turn signal on  for 
more than 
314 mile (1.2  km). 
Headlamp  High/Low  Beam  Changer 
To change your headlamps 
from low beams  to high 
beams, 
or high to low,  pull 
the multifunction lever  all 
the  way  toward you. Then 
release  it. 
When  the high beams  are on, this  light 
on the instrument 
panel  also will be 
on.

Making Thns 
I NOTICE: 
Making  very  sharp  turns  while  trailering  could 
cause  the  trailer 
to come  in  contact  with  the 
vehicle.  Your vehicle  could  be  damaged.  Avoid 
making  very 
sharp turns  while  trailering. 
When  you’re  turning  with a trailer, make wider 
turns than  normal. 
Do this so your trailer  won’t strike 
soft  shoulders,  curbs,  road signs,  trees  or  other  objects. 
Avoid  jerky  or  sudden maneuvers.  Signal well 
in advance. 
Turn Signals  When  Towing a Trailer 
When  you  tow a trailer, your vehicle  may need  a 
different  turn signal  flasher  and/or  extra  wiring. Check 
with  your Buick dealer.  The green arrows on your 
instrument panel  will flash  whenever  you signal  a turn 
or  lane  change.  Properly hooked  up, the trailer lamps 
will also  flash, telling  other  drivers  you’re about to turn, 
change lanes 
or stop. 
When towing 
a trailer, the green arrows on your 
instrument  panel will flash  for  turns even 
if the bulbs  on 
the trailer are burned out.  Thus, you  may  think drivers 
behind  you are seeing  your signal  when they are not.  It’s 
important  to  check occasionally to  be sure  the trailer 
bulbs  are still  working. 
Driving On Grades 
Reduce speed  and shift to  a lower gear before you  start 
down 
a long  or  steep  downgrade. If you don‘t  shift 
down,  you might have to  use your brakes 
so much that 
they would  get hot and  no  longer  work well. 
On 
a long  uphill  grade,  shift down  and reduce your 
speed to around 
45 mph (70 km/h)  to reduce the 
possibility 
of engine  and transaxle  overheating.
