2010 GMC SAVANA check engine light

•The message could display if the stability system
takes longer than usual to complete its diagnostic
checks due to driving conditions.
•The message displays if an engine or vehicle
related problem has been detected and the vehicle
needs service. See your dealer/retailer.
The message turns off as soon as the conditions that
caused the message to be displayed are no longer
present.
STARTING DISABLED SERVICE
THROTTLE
This message displays if the starting of the engine is
disabled due to the electronic throttle control system.
Have your vehicle serviced by your dealer/retailer
immediately.
This message only appears while the ignition is in
ON/RUN, and will not disappear until the problem is
resolved.
This message cannot be acknowledged.
TIGHTEN GAS CAP
This message may display and a chime may be heard
along with the check engine light on the instrument
panel cluster if the vehicle’s fuel cap is not tightened
properly. SeeMalfunction Indicator Lamp on page 4-31.Reinstall the fuel cap fully. SeeFilling the Tank on
page 6-10. The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
A loose or missing fuel cap allows fuel to evaporate
into the atmosphere. A few driving trips with the
cap properly installed should turn this light and
message off.
TIRE LEARNING ACTIVE
If your vehicle has the Tire Pressure Monitor System
(TPMS), this message displays when the system
is re-learning the tire positions on your vehicle. SeeDIC
Operation and Displays on page 4-38for more
information. The tire positions must be re-learned after
rotating the tires or after replacing a tire or sensor.
SeeTire Inspection and Rotation on page 6-69,
Tire Pressure Monitor System on page 6-65, and
Ination - Tire Pressure on page 6-63for more
information.
TRACTION CONTROL OFF
If your vehicle has StabiliTrak, this message displays
when the Traction Control System (TCS) is turned
off. Adjust your driving accordingly. SeeStabiliTrak
®
System on page 5-5for more information.

The brakes might not have time to cool between hard
stops. The brakes will wear out much faster with
a lot of heavy braking. Keeping pace with the traffic and
allowing realistic following distances eliminates a lot
of unnecessary braking. That means better braking
and longer brake life.
If the engine ever stops while the vehicle is being
driven, brake normally but do not pump the brakes.
If the brakes are pumped, the pedal could get harder
to push down. If the engine stops, there will still be some
power brake assist but it will be used when the brake
is applied. Once the power assist is used up, it can
take longer to stop and the brake pedal will be harder
to push.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modications
on page 6-3.
Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps prevent a
braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on. This is normal.If there is a problem with
the ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light on
page 4-29.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.

WARNING: (Continued)
•
Check again from time to time to be sure
snow does not collect there.
•Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
•Fully open the air outlets on or under the
instrument panel.
•Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting. See
Climate Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 3-38.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.Run the engine for short periods only as needed to
keep warm, but be careful.
To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine off
and close the window most of the way to save heat.
Repeat this until help arrives but only when you
feel really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery charged to restart
the vehicle and to signal for help with the headlamps.
Do this as little as possible to save fuel.

If it is decided to check the fluid level, be sure to follow
all the instructions here, or a false reading on the
dipstick may occur.
Notice:Too much or too little uid can damage
your transmission. Too much can mean that some
of the uid could come out and fall on hot engine
parts or exhaust system parts, starting a re.
Too little uid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission uid.
Wait at least 30 minutes with the engine Off, before
checking the transmission fluid level if the vehicle has
been driven:
•In hot weather, when outside temperatures are
above 32°C (90°F).
•The vehicle is heavily loaded.
•At high speed for quite a while in hot weather.
•In heavy traffic and hot weather.
•While pulling a trailer.
After driving under these conditions, a hot check can be
performed. The fluid should be Hot, which is 71°C
to 93°C (160°F to 200°F).
A cold fluid level check can be performed after the
vehicle has been sitting for eight hours or more with the
engine Off, but this is used only as a reference. Letthe engine run at idle for five minutes if outside
temperatures is between 15°C to 32°C (60°F to 90°F).
Should the fluid level be low during this cold check,
the fluid must be checked Warm or Hot before adding
fluid. If the outside temperature is colder than 15°C
(60°F) or hotter than 32°C (90°F), a cold check cannot
be performed.
A warm fluid level check can be performed by driving
the vehicle under lightly loaded conditions and outside
temperatures between 10°C to 27°C (50°F to 80°F). The
vehicle should be driven for at least 15 miles before
performing a warm check. Checking the fluid Warm or
Hot will give a more accurate reading of the fluid
level than a cold check.
Because the vehicle is equipped with a high-efficiency
air-to-oil cooler, the transmission fluid temperature
may not reach the required Hot fluid level checking
temperature under normal lightly loaded driving vehicle
conditions.Checking the Fluid Level
Prepare the vehicle as follows:
1. Park the vehicle on a level place. Keep the engine
running.
2. With the parking brake applied, place the shift lever
in P (Park).
