appears immediately after starting, it
is possible that the
generator can still recharge the battery. The battery should recharge while driving but may take a few hours
to do
so. Consider using an auxiliary charger (be sure to
follow the manufacturer’s instructions) to boost the
battery after returning home or to a final destination. If
this message appears while driving or after starting your
vehicle and stays on, have
it checked immediately to
determine the cause of this problem.

for more on this. Things that are especially important
in trailer operation are automatic transaxle fluid (don’t
overfill), engine oil, drive belt, cooling system and
brake adjustment.

severe operating conditions. See “Engine Overheating’’

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper Cadillac Service Manual. It tells
you much more about how to service your vehicle than
this manual can.
To order the proper service manual, see
“Service and Owner Publications” in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Vehicle” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record” in the Maintenance
Schedule Booklet.

Downloaded from www.Manualslib.com manuals search engine Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain. regularly reaches
90 OF (32 O C) or higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require change
until the message CHANGE
TRANS FLUID appears on
the Driver Information Center.
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done
at your Cadillac dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
1 NOTICE: - -1
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.

Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be rotated every 6,000 to S,O00 miles
(10 000 to 13 OOO km). Any time you notice unusual wear,
rotate
your tires as soon as possible and check wheel
alignment.
Also check for damaged tires or wheels. See
“When It’s Time for New Tires” and “Wheel
Replacement” later in
this section for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Maintenance Schedule
booklet
for scheduled rotation intervals.
When rotating
your tires, always use the correct rotation
pattern shown here. Don’t include the compact spare tire in
your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in
the Index.
I
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come
off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or
a paper towel to do this; but be
sure to use
a scraper or wire brush later, if you
need to, to get all the rust or dirt
off. (See
“Changing
a Flat Tire” in the Index.)

Downloaded from www.Manualslib.com manuals search engine Transportation Options*
Warranty work can frequently be handled in one day,
but there
is often no reason for you to wait at the
dealership. Cadillac helps minimize inconvenience
to you by providing several transportation options.
Depending on the circumstances, your dealership
can offer you one of the following options:
Shuttle Service*
Your dealership can provide you with shuttle service to
get you to your destination with minimal interruption of
your daily schedule when your Cadillac is unavailable
due to a warranty repair.
Courtesy Vehicle*
For repairs that require your vehicle to be unavailable to
you for an extended period of time, your dealer may
arrange to provide you with a courtesy vehicle from the
dealership, or one obtained from a local rental agency.
Miscellaneous Service*
Should the situation necessitate making your own
arrangements, Gold Key Courtesy Transportation
provides for reimbursement of personally arranged
transportation such as cab fare, reasonable fuel expenses
for a ride provided by another individual or a rental
vehicle obtained from an independent source.
*Some restrictions may apply. Please consult your
Cadillac dealer concerning specific Gold Key Courtesy
Transportation benefits oflered by the dealership.
Plan Ahead When Possible
Whenever possible, scheduling an appointment for your
vehicle’s warranty service and advising your service
consultant that you wish to take advantage of Gold Key
Courtesy Transportation can help minimize your
inconvenience by allowing your dealer to prepare arrangements
to fulfill your transportation needs in
advance of your visit.
