9-70 Driving and Operating
However, some gasolines contain
only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean
and avoid problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed
by the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found
at www.toptiergas.com.
For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change,
can help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.
Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive
called methylcyclopentadienyl
manganese tricarbonyl (MMT);
ask the attendant where you buy gasoline whether the fuel contains
MMT. We recommend against
the use of such gasolines. Fuels
containing MMT can reduce spark
plug life and affect emission
control system performance. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.
Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
For all other vehicles, use only the
unleaded gasoline described under
Recommended Fuel on page 9‑68.
We encourage the use of E85 in
vehicles that are designed to use it.
The ethanol in E85 is a
“renewable”
fuel, meaning it is made from
renewable sources such as corn
and other crops.

2. Get the vehicles close enoughso the jumper cables can reach,
but be sure the vehicles are
not touching each other. If they
are, it could cause a ground
connection you do not want. You
would not be able to start your
vehicle, and the bad grounding
could damage the electrical
systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put the automatic
transmission in P (Park) or a
manual transmission in
N (Neutral) before setting the
parking brake. If the vehicle has
a four-wheel-drive transfer case
with a N (Neutral) position, be
sure the transfer case is in a
drive gear, not in N (Neutral). Notice:
If the radio or other
accessories are left on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all the lamps that are not
needed. This avoids sparks and
helps save both batteries. And it
could save the radio! 4. Open the hood on the
other vehicle and locate the
positive (+) and negative (−)
terminal locations on that
vehicle.
Your vehicle has a remote
positive (+) jump starting
terminal and a remote
negative (−) jump starting
terminal. You should always use
these remote terminals instead
of the terminals on the battery.
If the vehicle has a remote
positive (+) terminal, it is located
under a red plastic cover at the
positive battery post. To uncover
the remote positive (+) terminal,
open the red plastic cover.

11-6 Service and Maintenance
First Engine Oil Change After
Every 160 000 km/100,000 Miles
.Automatic transmission fluid
change (normal service). See
Automatic Transmission Fluid on
page 10‑12.
.Four‐wheel drive only: Transfer
case fluid change (normal
service). Check vent hose at
transfer case for kinks and
proper installation. Check
to be sure vent hose is
unobstructed, clear, and free of
debris. During any maintenance,if a power washer is used to
clean mud and dirt from the
underbody, care should be
taken to not directly spray the
transfer case output seals.
High pressure water can
overcome the seals and
contaminate the transfer case
fluid. Contaminated fluid will
decrease the life of the transfer
case and should be replaced.
.Spark plug replacement and
spark plug wires inspection.
An Emission Control Service.
First Engine Oil Change After
Every 240 000 km/150,000 Miles
.Engine cooling system drain,
flush, and refill (or every
five years, whichever occurs
first). See
Engine Coolant on
page 10‑17. An Emission
Control Service.
.Engine drive belts inspection
for fraying, excessive cracks,
or obvious damage (or every
10 years, whichever occurs
first). Replace, if needed.
