Engine Coolant - Cadillac 2004 XLR Owner's Manual

Notice: We recommend you use only fluid labeled
®
DEXRON -III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON
not covered by your new vehicle warranty.
Change both the fluid and filter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
•
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•
In hilly or mountainous terrain.
•
High performance operation.
If you do not use your vehicle under one of these
conditions, change the fluid and filter every
100,000 miles (166 000 km).
See Scheduled Maintenance on page 6-4 for the proper
service intervals for the transmission fluid and filter.
