2009 Cadillac XLR Owners Manual - Accessory Power Outlet



Accessory Power Outlet

This feature can turn the lamps on and off for you. A light sensor on top of the instrument panel makes the Twilight Sentinel® work, so be sure it is not covered.

With Twilight Sentinel® you will see the following happen:

  • When it is dark enough outside, the front turn signal lamps (DRL) will go off, and the headlamps and parking lamps will come on. The other lamps that come on with headlamps will also come on.
  • When it is bright enough outside, the headlamps will go off, and the front turn signal lamps (DRL) will come on, as long as the exterior lamp switch is in the AUTO position.

If the vehicle is started in a dark garage, the automatic headlamp system will come on immediately. Once the vehicle leaves the garage, it takes about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in full bright position

You can idle the vehicle with the lamps off, even when it is dark outside. After starting the vehicle, turn the exterior lamp control band to off, then release it. The lamps will remain off until you turn the control band to off again.

Twilight Sentinel® also provides exterior illumination as you leave the vehicle. If Twilight Sentinel® has turned on the lamps when you turn off the ignition, the lamps will remain on until:

  • The exterior lamp switch is moved from OFF to the parking lamp position, or
  • the delay time selected has elapsed.

If the ignition is turned off with the exterior lamp switch in the parking lamp or headlamp position, the Twilight Sentinel® delay will not occur. The lamps will turn off as soon as the switch is turned off.

The regular headlamp system should be turned on when needed.

Exterior Lighting Battery Saver

If the manual parking lamps or headlamps have been left on, the exterior lamps will turn off as soon as the ignition is turned off or Retained Accessory Power (RAP) is active. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps on. The battery saver does not work if the headlamps are turned on after the ignition switch is turned to off.

If you need to leave the lamps on, use the exterior lamp control to turn the lamps back on

Instrument Panel Brightness

The button for this feature is located on the instrument panel to the left of the steering column.

- (Brightness): Press to change the brightness of the instrument panel lights.

Press the DIMMER button until PANEL DIMMING appears on the Driver Information Center (DIC). Then use the brightness button to adjust the instrument panel brightness. Press the top or bottom of the button to brighten or dim the lights.

Be sure not to have the brightness turned all the way down with the lamps on during the day. The DIC may not be visible.

Courtesy Lamps

When any door or the trunk lid is opened, the interior lamps will go on unless it is bright outside. Press the interior lamp button on the right side of the instrument panel, to turn the courtesy lamps on or off.

Entry/Exit Lighting

With entry lighting, the interior lamps will come on when entering the vehicle. The interior lamps will come on for about 20 seconds when the engine is turned off. You can turn exit and entry lighting off by quickly turning the courtesy lamps on and off.

Reading Lamps

The inside rearview mirror includes two reading lamps. The lamps will go on when a door is opened. When the doors are closed, each lamp can be turned on individually by pressing the button for that lamp.

Battery Run-Down Protection

The vehicle has a feature to help prevent the battery from being drained, in case the underhood lamp, vanity mirror lamps, cargo lamps, reading lamps, console, or glove box lamps are accidentally left on, or something is left plugged into the accessory power outlet or cigarette lighter. If any of the accessory lamps are left on, they will automatically time-out after about 10 minutes. To reset the battery protection, all of the above lamps must be turned off or the ignition must be in the ACC/ACCESSORY position.

Head-Up Display (HUD)

CAUTION:

If the HUD image is too bright, or too high in your field of view, it may take you more time to see things you need to see when it is dark outside. Be sure to keep the HUD image dim and placed low in your field of view.

The Head-Up Display (HUD) allows you to see some of the driver information that appears on the instrument panel cluster.

The information may be displayed in English or metric units and appears as an image focused out toward the front of the vehicle.

The HUD consists of the following information:

  • Speedometer
  • Turn Signal Indicators
  • High-Beam Indicator Symbol
  • Tap-Up/Tap-Down Transmission Feature
  • Check Gages Message
  • Adaptive Cruise Control Features and Indicators
  • Radio Features

Continue to scan the displays, controls and driving environment just as you would in a vehicle without HUD. Check the instrument panel cluster, to be sure you do not miss something important, such as a warning light. Under important warning conditions, the CHECK GAGES message will display in the HUD. View the Driver Information Center (DIC) for more information.

The HUD controls are located to the left of the steering wheel.

- (Brightness): Use to adjust the brightness of the HUD and the instrument panel cluster.

DIMMER: Use to select the HUD or the instrument panel cluster to adjust the brightness.

HUD: Use to adjust the vertical position of the HUD display.

To adjust the HUD so you can see it properly, do the following

  1. Adjust the seat to a comfortable driving position. If you change the seat position later, you may have to re-adjust the HUD.
  2. Start the engine and press the top or bottom of the HUD button to center the HUD image in your view. The HUD image can only be adjusted up and down, not side-to-side.
  3. Press the DIMMER button until the DIC reads HUD DIMMING. Then use the brightness button to adjust the desired intensity.

The brightness of the HUD image is determined by the light conditions in the direction the vehicle is facing and where you have the HUD set. If you are facing a dark object or a heavily shaded area, the HUD may anticipate that you are entering a dark area and may begin to dim.

To turn off the HUD, press the brightness button down until the image disappears.

Polarized sunglasses could make the HUD image harder to see.

As light shines out from the HUD, it is possible for light to shine back in. In rare occurrences, when the sun is at a specific angle and position, the sun’s rays can shine back into the HUD. When this occurs, the display device within the HUD will be temporarily illuminated. The event will end when the vehicle’s angle to the sun changes.

Clean the inside of the windshield as needed to remove any dirt or film that reduces the sharpness or clarity of the HUD image.

To clean the HUD, spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit.

If the ignition is on and you cannot see the HUD image, check to see if:

  • Something is covering the HUD unit.
  • The brightness is adjusted properly.
  • The HUD image is adjusted to the proper height.
  • Ambient light in the direction the vehicle is facing is low.
  • A fuse is blown.

Keep in mind that the windshield is part of the HUD system.

The following Adaptive Cruise Control (ACC) messages may appear in the HUD:

CRUISE SPEED LIMITED: This message indicates that the vehicle speed has been reduced below the set speed due to ACC limitations. The set speed is too high and ACC cannot detect other vehicles at far enough distances for the system to operate properly.

TIGHT CURVE: This message indicates that ACC has reduced the vehicle speed due to a tight curve in the road. Once the road straightens, ACC will return to the selected set speed or follow distance setting.

You may also see an ACC active symbol, alert symbol or vehicle ahead symbol. See “Adaptive Cruise Control (ACC)” under Turn Signal/Multifunction Lever on page 3-7 for more information.
