Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat.
If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to
indicate that you have used your tape player for
50 hours without resetting the tape clean timer. If this
message appears on the display, your cassette
tape player needs to be cleaned. It will still play tapes,
but you should clean it as soon as possible to
prevent damage to your tapes and player. If you notice
a reduction in sound quality, try a known good
cassette to see
if the tape or the tape player is at fault.
If this other cassette has no improvement in sound
quality, clean the tape player.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealership. The
cut tape detection feature of your cassette tape
player may identify the cleaning cassette tape as
a damaged tape,
in error. To prevent the cleaning
cassette from being ejected, use the following steps:
1.
2.
3.
4.
5.
Turn the ignition on.
Turn the radio
off.
Press and hold the TAPE/PLAY button for five
seconds. The tape symbol on the display will
flash for two seconds.
Insert the scrubbing action cleaning cassette.
Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
After the cleaning cassette is ejected, the cut tape
detection feature will be active again.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to
clean the tape head. This type of cleaning cassette will
not eject on its own. A non-scrubbing action cleaner
may not clean as thoroughly as the scrubbing type
cleaner. The use of a non-scrubbing action, dry-type
cleaning cassette is not recommended.
After you clean the player, press and hold EJECT for
five seconds to reset the CLN indicator. The radio
will display
--- to show the indicator was reset.

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads. Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have
to
do all the work of slowing down. They could

thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.

so hot that they wouldn’t work well. You would
then have poor braking or even none going
down a
hill. You could crash. Shift down to let
your engine assist your brakes on
a steep
downhill slope.
Know how to go uphill. You may want to shift down to
a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area or
winding roads. Be alert to these and take appropriate
action.

When to Change Engine Oil (GM Oil
Life SystemTM)
Your vehicle has a computer system that lets you know
when to change the engine
oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated
can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary.
A CHANGE OIL SOON light will come on.
Change your
oil as soon as possible within the next two
times you stop for fuel.
It is possible that, if you are
driving under the best conditions, the oil life system may
not indicate that an oil change is necessary for over a
year. However, your engine oil and filter must be
changed at least once a year and at this time the system
must be reset. It is also important to check your oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember
to reset the oil life system
whenever the oil is changed.
How to Reset the GM Oil Life System
The GM Oil Life SystemTM calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system
so it can calculate
when the next oil change is required.
If a situation occurs
where you change your oil prior to a CHANGE
OIL SOON
light being turned on, reset the system.
To reset the GM Oil Life SystemTM after the oil has
been changed, use one of the following two procedures:
Using the Driver Information Center (DIC)
1.
2.
3.
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 after the light stops flashing,
then start the vehicle.
If the CHANGE OIL SOON light comes back on, the
engine oil life monitor has not reset. Repeat the
procedure.
Using the Trip Computer (If Equipped)
1. Press the MODE button until the light appears lit
2. Press and hold the RESET button for three seconds.
next to
OIL LIFE.
The
oil life percentage should change to 100%.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together
if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality
GM
brake parts. When you replace parts of your braking
system
- for example, when your brake linings
wear down and you need new ones put in
- be sure
you get new approved
GM replacement parts. If
you don’t, your brakes may no longer work properly.
For example,
if someone puts in brake linings that are
wrong for your vehicle, the balance between your
front and rear brakes can change
- for the worse.
The braking performance you’ve come to expect can
change in many other ways
if someone puts in the
wrong replacement brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelco@ battery. When it’s time for a new battery, get
one that has the replacement number shown on the
original battery’s label. We recommend an ACDelco@
battery. See Engine Compartment Overview on
page
5- 12 for battery location.
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
If your battery has a very low charge or is dead, you
may not be able to remove the ignition key from
the ignition switch or shift out of Park (P). Refer to
Shifting Out of Park
(P) on page 2-30.
