INSTRUMENTS AND CONTROLS 117
Here are four things that some owners
ask about. None of these show a
problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel to
fill up than the gauge indicated.
For example, the gauge may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank's capacity
to fill the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds to
stabilize after the ignition is
turned on, and goes back to empty
when the ignition is turned off.Engine Coolant
Temperature Gauge
Base Level
Uplevel Balanced Configuration
This gauge measures the engine
coolant temperature.
The warning area at the far end of the
gauge may appear shaded or may be
colored red.
If the pointer approaches the warning
area, or the shaded thermostat symbol
the engine may be too hot.
Under some driving conditions,
including those listed below, it is
normal for the temperature to rise
above the usual operating range and
approach the far end of the gauge:
. Stop and go driving in heavy
traffic.

Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:. Fuel with any amount of
methanol, methylal, and
aniline. These fuels can
corrode metal fuel system
parts or damage plastic and
rubber parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control system
and spark plugs.
. Fuel with a posted octane
rating of less than the
recommended fuel. Using this
fuel will lower fuel economy
and performance, and may
decrease the life of the
emissions catalyst.
Fuel Additives
Gasoline should contain detergent
additives that help prevent engine and
fuel system deposits from forming.
Clean fuel injectors and intake valves
will allow the emission control system
to work properly. Some gasoline does
not contain sufficient quantities of
additives to keep fuel injectors and
intake valves clean. To make up for
this lack of detergency, consult your
dealer for the GM approved additive
treatment. Add this additive to the
fuel tank at every engine oil change or
every 15 000 km (9,000 mi), whichever
occurs first.
Filling the Tank
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.

Warning (Continued)
.To help avoid injuries to you
and others, read and follow
all the instructions on the
fuel pump island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.
. Do not leave the fuel pump
unattended.
. Do not use a cell phone while
refueling.
. Do not reenter the vehicle
while pumping fuel.
. Keep children away from the
fuel pump and never let
children pump fuel.
. Fuel can spray out if the
refueling nozzle is inserted
too quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot

weather. Insert the refueling
nozzle slowly and wait for any
hiss noise to stop prior to
beginning to flow fuel.
If equipped, the fuel door is locked
when the vehicle doors are locked.
Press
Kon the RKE transmitter to
unlock. To open the fuel door, push
and release the rearward center edge
of the door. The vehicle has a capless refueling
system and does not have a fuel cap.
The filling nozzle must be fully
inserted and latched prior to starting
fuel flow.
{Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:
. Vehicle performance issues,
including engine stalling and
damage to the fuel system.
. Fuel spills.
. Potential fuel fires.
Be careful not to spill fuel. Wait a few
seconds before removing the nozzle.
After initial shutoff, do not partially
remove the nozzle to add more fuel as
this will result in fuel spillage. Clean
fuel from painted surfaces as soon as
possible. See Exterior Care0278.
{Warning
If a fire starts while you are
refueling, do not remove the nozzle.
Shut off the flow of fuel by shutting
off the pump or by notifying the
station attendant. Leave the area
immediately.
Filling the Tank with a Portable
Gas Can
If the vehicle runs out of fuel and
must be filled from a portable gas can:
1. Locate the capless funnel adapter from under the carpet in
the trunk.
2. Insert and latch the funnel into the capless fuel system.

spillage and damage the capless
fuel system. This could cause a fire
and you or others could be badly
burned and the vehicle could be
damaged.
3. Remove and clean the funnel adapter and return to the storage
location.
Filling a Portable Fuel
Container
{Warning
Filling a portable fuel container
while it is in the vehicle can cause
fuel vapors that can ignite either by
static electricity or other means.
You or others could be badly
burned and the vehicle could be
damaged. Always:
