Engine Coolant - GMC Hummer H3 2008 Owner's Handbook Manual

After the CHANGE OIL message
comes on, change the engine
oil as soon as possible within
1000 kilometres (600 miles).
Even if the oil life system does not
indicate that an oil change is
necessary, the engine oil and filter
must be changed at least once a
year.
It is normal for an engine to use
some oil, and some engines use
more oil when they are new. It is
the owner's responsibility to check
the engine oil level regularly.
After you change the oil, you need
to reset the engine oil life monitor.
See "Driver Information Centre" in
Section 1 for information on the
engine oil life monitor.
Engine damage resulting from
improper maintenance is not
covered by the New Vehicle
Warranty.
Section 4

Engine Coolant

CAUTION
If your engine overheats, see
"Engine Overheating" in
Section 5. Continued operation
of the overheated engine, even
for a short time, may result in
a fire and the possibility of
personal injury and/or severe
vehicle damage.
The cooling system in your vehicle
is designed to use a coolant (a
mixture of ethylene glycol, corro-
sion inhibitors and water) rather
than plain water. Use a 50/50
mixture of clean water and DEX-
®
COOL coolant. If you use this
mixture, you don't need to add
anything else.
