Seats and Restraints

If the child restraint has been installed and the on indicator is lit, see “If the On Indicator is Lit for a Child Restraint” under Passenger Sensing System on page 3‑35 for more information. To remove the child restraint, unbuckle the vehicle safety belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it.

Securing Child Restraints (Front Seat-Airbag On/Off Switch) This vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 3‑49. On vehicles with an airbag on/off switch, you can use this feature to turn off the right front passenger frontal airbag. The switch is located on the instrument panel. See Airbag

On-Off Switch on page 3‑32 for more information, including important safety information. A label on the sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys.

{ WARNING

A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the right front passenger airbag inflates and the passenger seat is in a forward position.

(Continued)

WARNING (Continued)

Even if the airbag switch has turned off the right front passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. Secure rear-facing child restraints in a rear seat, even if the airbag is off. If you secure a forward-facing child restraint in the right front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat.

GMC Savana Owner Manual - 2011

Black plate (63,1)

{ WARNING If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. For example, the right front passenger airbag could inflate even though the airbag on-off switch is turned off. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 5‑17 for more information, including important safety information.

If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off. If the child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH

System) on page 3‑50 for how and where to install the child restraint using LATCH. If a child restraint is secured using a safety belt and it uses a top tether, see Lower Anchors and Tethers for Children (LATCH System) on page 3‑50 for top tether anchor locations. Do not secure a child seat in a position without a top tether anchor if a national or local law requires that the top tether be anchored, or if the instructions that come with the child restraint say that the top strap must be anchored. In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. You will be using the lap-shoulder belt to secure the child restraint in this position. Follow the instructions that came with the child restraint. 1. Move the seat as far back as it

will go before securing the forward-facing child restraint.

Seats and Restraints

If you have no other choice but to install a rear-facing child restraint in this seat, make sure the airbag is off once the child restraint has been installed. When the airbag off switch has turned off the right front passenger frontal airbag, the off indicator in the airbag off light should light and stay lit when the vehicle is started. See Airbag On-Off Light on page 5‑18.

7.

If the vehicle does not have a rear seat and the child restraint has a top tether, follow the child restraint manufacturer's instructions regarding the use of the top tether. See Lower Anchors and Tethers for Children (LATCH System) on page 3‑50 for more information.

8. Before placing a child in the

child restraint, make sure it is securely held in place. To check, grasp the child restraint at the safety belt path and attempt to move it side to side and back and forth. When the child restraint is properly installed, there should be no more than 2.5 cm (1 in) of movement.

To remove the child restraint, unbuckle the vehicle safety belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it. If you turned the airbag off with the switch, turn on the right front passenger airbag when you remove the child restraint from the vehicle unless the person who will be sitting there is a member of a passenger airbag risk group. See Airbag On-Off Switch on page 3‑32 for more information, including important safety information.

Compass This vehicle may have a compass in the Driver Information Center (DIC).

Compass Zone Your dealer will set the correct zone for your location. Under certain circumstances, such as during a long distance cross-country trip or moving to a new state or province, it will be necessary to compensate for compass variance by resetting the zone through the DIC if the zone is not set correctly.

GMC Savana Owner Manual - 2011

Black plate (5,1)

Compass variance is the difference between the earth's magnetic north and true geographic north. If the compass is not set to the zone where you live, the compass may give false readings. The compass must be set to the variance zone in which the vehicle is traveling. To adjust for compass variance, use the following procedure:

Compass Variance (Zone) Procedure 1. Do not set the compass zone

when the vehicle is moving. Only set it when the vehicle is in P (Park).

Press T until PRESS V TO CHANGE COMPASS ZONE displays.

2. Find the vehicle's current

location and variance zone number on the map. Zones 1 through 15 are available.

3. Press V to scroll through and select the appropriate variance zone.

The fuel gauge, when the ignition is on, indicates how much fuel is left in the vehicle fuel tank. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on. The gauge first indicates empty before the vehicle is out of fuel, and the fuel tank should be refueled soon. Listed are four situations customers might experience with the fuel gauge. None of these indicate a problem with the fuel gauge: . At the gas station, the fuel pump

shuts off before the gauge reads full.

It takes a little more or less fuel to fill up than the fuel 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 does not go back to empty when the ignition is turned off.

The oil pressure gauge shows the engine oil pressure in psi (pounds per square inch) or kPa (kilopascals) when the engine is running. Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range.

A reading in the low pressure zone may be caused by a dangerously low oil level or other problem causing low oil pressure. Check the oil as soon as possible.

{ WARNING

Do not keep driving if the oil pressure is low. The engine can become so hot that it catches fire. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced.

Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule for changing engine oil.

When the engine is running, the gauge shows the condition of the charging system. Readings between the low and high warning zones indicate the normal operating range. Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. The vehicle can be only driven for a short time with the reading in either warning zone. If it must be driven, turn off all unnecessary accessories. Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible.

Charging System Light

This light comes on briefly when the ignition key is turned to START, but the engine is not running, as a check to show it is working. If it does not, have the vehicle serviced by your dealer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system message in the Driver Information Center (DIC) can also appear.

See Battery Voltage and Charging Messages on page 5‑32 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner.

Malfunction Indicator Lamp A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It ensures that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment.

GMC Savana Owner Manual - 2011

Notice: If the vehicle is continually driven with this light on, after a while, the emission controls might not work as well, the vehicle fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by the vehicle warranty. Notice: Modifications made to the engine, transmission, exhaust, intake, or fuel system of the vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect the vehicle's emission controls and can cause this light to come on. Modifications to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to

pass a required Emission Inspection/Maintenance test. See Accessories and Modifications on page 10‑4. This light comes on during a malfunction in one of two ways: Light Flashing: A misfire condition has been detected. A misfire increases vehicle emissions and could damage the emission control system on the vehicle. Diagnosis and service might be required. To prevent more serious damage to the vehicle: . Reduce vehicle speed. . Avoid hard accelerations. . Avoid steep uphill grades.

If towing a trailer, reduce the amount of cargo being hauled as soon as it is possible.

This light should come on when the ignition is on, but the engine is not running, as a check to show it is working. If it does not, have the vehicle serviced by your dealer. If the Malfunction Indicator Lamp comes on and stays on while the engine is running, this indicates that there is an OBD II problem and service is required. Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction.

If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park the vehicle. Turn the vehicle off, wait at least 10 seconds, and restart the engine. If the light is still flashing, follow the previous steps and see your dealer for service as soon as possible. Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required. The following may correct an emissions system malfunction: . Make sure the fuel cap is

fully installed. See Filling the Tank on page 9‑44. 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 the light off.

. Make sure the electrical

system is not wet. The system could be wet if the vehicle was driven through a deep puddle of water. The condition is usually corrected when the electrical system dries out. A few driving trips should turn the light off. . Make sure to fuel the vehicle

with quality fuel. Poor fuel quality causes the engine not to run as efficiently as designed and can cause: stalling after start-up, stalling when the vehicle is changed into gear, misfiring, hesitation on acceleration, or stumbling on acceleration. These conditions might go away once the engine is warmed up.

If one or more of these conditions occurs, change the fuel brand used. It will require at least one full tank of the proper fuel to turn the light off. See Recommended Fuel on page 9‑40.

If none of the above have made the light turn off, your dealer can check the vehicle. The dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that might have developed. Emissions Inspection and Maintenance Programs Some state/provincial and local governments may have programs to inspect the on-vehicle emission control equipment. For the inspection, the emission system test equipment is connected to the vehicle’s Data Link Connector (DLC).

down. The diagnostic system evaluates critical emission control systems during normal driving. This can take several days of routine driving. If this has been done and the vehicle still does not pass the inspection, your dealer can prepare the vehicle for inspection.

Brake System Warning Light The vehicle brake system consists of two hydraulic circuits. If one circuit is not working, the remaining circuit can still work to stop the vehicle. For normal braking performance, both circuits need to be working. If the warning light comes on, there could be a brake problem. Have the brake system inspected right away.

The DLC is under the instrument panel to the left of the steering wheel. See your dealer if assistance is needed. The vehicle may not pass inspection if:

The malfunction indicator lamp is on with the engine running, or if the light does not come on when the ignition is turned to ON/RUN while the engine is off. The critical emission control systems have not been completely diagnosed by the system. This can happen if the battery has recently been replaced or if the battery has run

The trip odometer has a feature called the retro-active reset. This can be used to set the trip odometer to the number of kilometers (miles) driven since the ignition was last turned on. This can be used if the trip odometer is not reset at the beginning of the trip. To use the retro-active reset feature, press and hold V for at least four seconds. The trip odometer will display the number of kilometers (km) or miles (mi) driven since the ignition was last turned on and the vehicle was moving. Once the vehicle begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 8 km (5 miles) before it is started again, and then the retro-active reset feature is activated, the display will show 8 km (5 miles). As the vehicle begins moving, the display will then increase to 8.1 km (5.1 miles), 8.2 km (5.2 miles), etc.

If the retro-active reset feature is activated after the vehicle is started, but before it begins moving, the display will show the number of kilometers (km) or miles (mi) that were driven during the last ignition cycle.

Fuel Range Press 3 until FUEL RANGE displays. This display shows the approximate number of remaining kilometers (km) or miles (mi) the vehicle can be driven without refueling. The display will show LOW if the fuel level is low. The fuel range estimate is based on an average of the fuel economy over recent driving history and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this display may read one number, but if the vehicle is driven on a freeway, the number may change even though the same amount of fuel is in the

fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. If the vehicle is low on fuel, the FUEL LEVEL LOW message will be displayed. See “FUEL LEVEL LOW” under Fuel System Messages on page 5‑36 for more information.
