The  exit speed is usually posted. 
Reduce your speed according  to your speedometer, not 
to  your sense  of motion. After driving  for any  distance 
at higher speeds,  you  may tend to think  you are going 
slower  than you actually 
are. 
Before Leaving on a Long  Trip 
Make  sure  you’re  ready.  Try to  be well rested.  If you 
must start when you’re not  fresh -- such as  after  a day’s 
work 
-- don’t plan to make  too many miles that  first part 
of  the journey.  Wear comfortable  clothing  and shoes  you 
can easily  drive in. 
Is your vehicle ready  for a long  trip? If  you keep it 
serviced and maintained,  it’s ready 
to go. If it needs 
service, have  it done  before  starting 
out. Of course, 
you’ll  find experienced and  able  service  experts  in 
Buick dealerships all across North America.  They’ll be 
ready and willing to help 
if you need it.  Here 
are some things  you can check before 
a trip:

Is the tread good enough for 
long-distance  driving? Are the tires  all inflated to the 
recommended pressure?

along your route? Should  you delay  your trip a  short 
time  to avoid a major storm system? 
Maps: Do you have up-to-date  maps?

How to Add Coolant to  the Coolant 
Recovery  Tank 
If you haven’t  found  a  problem yet,  but  the  coolant  level 
isn’t  at  the  COLD  mark,  add  a 
50/50 mixture  of clean 
water (preferably  distilled)  and DEX-COOL@  engine 
coolant  at the  coolant  recovery tank.  (See  “Engine 
Coolant”  in  the  Index  for  more  information.) 
A CAUTION: 
Adding  only  plain water to your  cooling  system 
can be  dangerous.  Plain water,  or some  other 
liquid  like  alcohol,  can boil  before  the proper 
coolant  mixture  will.  Your  vehicle’s  coolant 
warning  system  is  set for  the  proper  coolant 
mixture.  With  plain water or the  wrong  mixture, 
your  engine  could  get  too 
hot but you  wouldn’t 
get  the  overheat  warning.  Your  engine  could 
catch  fire  and  you or others  could  be  burned. 
Use 
a 50/50 mixture of clean  water  and 
DEX-COOL@ coolant. 
I NOTICE: 
In cold  weather,  water can freeze and crack  the 
engine,  radiator, heater  core and  other  parts. 
Use  the recommended  coolant  and  the  proper 
coolant  mixture.

To provide  cleaner air, all gasolines  in the United  States 
are  now  required  to  contain  additives  that will help 
prevent  deposits  from forming in your  engine  and fuel 
system,  allowing  your emission control system to 
function  properly.  Therefore,  you should  not have to add 
anything  to  the  fuel. In addition,  gasolines  containing 
oxygenates,  such as ethers and ethanol,  and 
reformulated  gasolines  may be  available  in your  area  to 
help  clean  the air. General Motors recommends  that  you 
use  these  gasolines  if they comply with the 
specifications  described  earlier. 
1 NOTICE: 
Your  vehicle  was  not  designed  for  fuel  that 
contains  methanol.  Don’t  use 
it. It  can  corrode 
metal  parts  in  your  fuel  system  and  also  damage 
plastic  and  rubber  parts.  That  damage  wouldn’t  be  covered  under  your  warranty. 
Fuels  in  Foreign  Countries 
If  you  plan on driving  in another country  outside the 
United  States  or  Canada, the proper  fuel may  be hard  to 
find.  Never  use leaded  gasoline  or  any other  fuel  not 
recommended  in the previous text on  fuel.  Costly  repairs 
caused  by use  of improper  fuel wouldn’t be covered  by 
your warranty. 
To check on fuel availability, ask  an auto  club,  or 
contact  a  major oil company that does  business  in the 
country where  you’ll be driving. 
You  can also  write  us at the following  address  for 
advice.  Just  tell us where you’re going and give your

What Kind of Engine  Oil to Use 
Oils recommended  for your  vehicle  can  be identified  by 
looking  for  the “Starburst” symbol.  This symbol 
indicates  that the oil has  been  certified  by the American 
Petroleum  Institute  (API). 
Do not use  any oil which 
does  not carry  this  Starburst  symbol. 
If  you change your own oil, 
be  sure 
you use  oil that has 
the  Starburst  symbol on the 
front  of the  oil container. 
I RECOMMENDED  SAE  VISCOSITY  GRADE  ENGINE OILS 
If you have your oil changed for you,  be  sure  the oil put 
into  your  engine  is American Petroleum  Institute 
certified  for  gasoline  engines.  You should  also  use  the 
proper  viscosity  oil  for your vehicle,  as shown  in the 
following  chart:

ProCarManuals.com 

As shown in the  chart, SAE 1OW-30 is best  for your 
vehicle. However,  you can 
use SAE 5W-30 if  it’s going 
to  be  colder  than 
60°F (1 6 O C) before your next oil 
change. When  it’s  very cold, 
you should use SAE 
5W-30.  These numbers  on an oil  container show  its 
viscosity,  or thickness. 
Do not  use other  viscosity oils, 
such 
as SAE 20W-50. 
NOTICE: 
Use  only  engine  oil  with  the  American  Petroleum 
Institute  Certified  For  Gasoline  Engines 
“Starburst”  symbol.  Failure  to  use  the 
recommended  oil  can  result  in  engine  damage  not 
covered  by  your  warranty. 
GM Goodwrench@  oil meets all the requirements for 
your vehicle. 
If you are in an  area where  the temperature falls below 
-20°F 
(-29”C), consider  using either  an SAE 5W-30 
synthetic  oil or an SAE OW-30 oil.  Both will  provide 
easier  cold  starting  and better protection  for your  engine 
at extremely low temperatures. 
Engine  Oil  Additives 
Don’t add anything  to your oil.  Your dealer  is ready to 
advise  if  you think something should  be added. 
When to Change  Engine Oil 
Your  vehicle has an  Oil  Life Monitor.  This  feature 
will  let you  know when to change your oil  and 
filter 
-- usually between 3,000 miles (5 000 km) and 
7,500 miles (12 500 km)  since  your last oil change. 
Under  severe  conditions, the indicator  may come on 
before 
3,000 miles (5 000 km). Never  drive your vehicle 
more than 
7,500 miles (12 500 km) or 12 months 
(whichever occurs first) without an  oil  change. 
The  system  won’t detect  dust 
in the oil. So, if you 
drive in a dusty area,  be sure  to change your oil every 
3,000 miles (5 000 km) or sooner. Remember to reset 
the CHANGE  OIL 
SOON light when the oil has been 
changed.  For more information,  see “Change Oil Soon 
Light”  in the Index. 
How to  Reset  the CHANGE OIL SOON Light 
After changing the  engine oil, the system must be reset. 
With the ignition  key in RUN  but the  engine off, fully 
push and release the accelerator pedal slowly three times 
within  five seconds.  If 
the CHANGE OIL SOON light 
flashes, the system  is resetting. 
Turn the  key to OFF,

Supercharger Oil 
Unless you  are technically qualified and have the proper 
tools, 
you should let your  dealer  or  a qualified  service 
center  perform this  maintenance. 
When  to  Check 
Check oil level  every  30,000 miles (50 000 km) or every 
36 months, whichever  occurs first. 
What Kind of Oil to Use 
See  “Recommended  Fluids and Lubricants”  in the Index 
and  use only  the recommended  oil.

How to Add Fluid 
Refer to the Maintenance  Schedule to determine  what 
kind  of transaxle  fluid  to  use.  See “Recommended 
Fluids  and Lubricants”  in the Index. 
If  the  fluid  level  is low,  add only enough 
of the  proper 
fluid  to  bring  the 
level into  the  cross-hatched  area on 
the  dipstick. 
1. Pull  out the dipstick. 
2.  Using  a long-neck  funnel, add enough  fluid at 
the 
dipstick  hole  to  bring it to the proper  level. 
It  doesn’t  take much  fluid, generally  less than  one 
pint 
(0.5 L). Don’t overfill. 
NOTICE: 
We  recommend  you  use  only  fluid  labeled 
DEXRON@-111, because  fluid  with  that  label  is 
made  especially  for  your  automatic  transaxle. 
Damage  caused  by  fluid  other  than 
DEXRON-I11 
is  not  covered  by  your  new  vehicle  warranty. 
3. After  adding  fluid, recheck  the  fluid  level  as 
described  under  “How  to Check.”  4. 
When  the correct  fluid  level is  obtained,  push the 
dipstick  back in all the  way. 
Engine Coolant 
The  cooling s stem in your vehicle is filled  with 
DEX-COOL  engine  coolant.  This  coolant  is designed 
to remain  in your  vehicle  for 5 years or 150,000 miles 
(240 
000 km)  whichever  occurs  first, if you  add only 
DEX-COOL6  extended  life  coolant. 
J 
The  following  explains your cooling  system and  how to 
add  coolant  when it is low.  If 
you have a problem  with 
engine  overheating  or  if you  need 
to add coolant  to your 
radiator,  see “Engine Overheating” 
in the  Index. 
A 50/50 mixture  of water and DEX-COOL@ 
coolant will: 
Give  freezing  protection down  to -34°F (-37°C). 
Give boiling protection  up to 265 “F (1 29°C). 
Protect  against rust and corrosion.
