Press remote transmitter "UNLOCK" button once OR turn the ignition switch to the "ON" position and press programming button for one second (see below).
The vehicle interior (courtesy) light and door open warning light (DOOR AJAR indicator) will then illuminate for 60 seconds when the ignition is turned off, or until the doors are locked with the remote transmitter. Yes, the dashboard instrument panel lights will flash when the parking lights flash.

Code Alarm Programming Button is under dashboard on the kick panel by the driver's left knee, left of the steering column. If you can't find it, it might still be tucked up in the wiring harness higher up in that same general area. The botton is recessed in a plastic ring (see diagram).
This button must be pressed while programming remotes or if the battery was disconnected and the lights are flashing.

Measure your oil at normal operating temp, without the engine running of course. This will give you a more accurate reading once the oil has circulated in the system.

The system works like this:

• With the ignition on, the oil pressure indicator light on the dash should come on and flash. Once the engine is started, the light should go out and stay out as long as the engine is running.
• If the oil pressure drops below approximately 0.3 bar or 5 psi when the engine is running below 2000 rpm, the light will flash.
• If the oil pressure drops below approximately 1.8 bar or 27 psi when the engine is running above 2000 rpm for more than 3 seconds, the indicator light will flash and the buzzer will sound.

If either this two warnings occur:

• The engine should be switched off immediately and the oil level should be checked.
  

Hi:
The only red warning light that is in the center of the dash is either the brake warning light or possibly the low tire pressure light?

Here is a link to the manual online, and you can look thru the warning light descriptions and actually search this electronic document:

hi ya it seems one of the door switches is broken or disengaged on each door frame you will find a push in switch witch operates the interior light, door warning light on dash and remote locking if one of them is not working it will show on dash as a door not closed it will prevent the interior light from working and also stop the auto locking system from working properly the locking system is connected to the interior lights
Hope yhis helps

Vehicle not all the way in Park or Neutral? Bad battery? Bad battery cable? Bad Transmission range selelector switch? Bad Starter? Bad starter relay? Onboard security system disabling start circuit? Locked-up engine?

What is working and what is not? Headlamps? Interior dome lamps? Radio? Warning lamps on dash? Is the "Security" light flashing?

Is it making any noises when you turn the key?

It stands for Vehicle Stability Control When the VSC system takes control it activiates stability correction. The slip indication light flashes while the buzzer activates. The VSC is able to operate at all times except when the centre differential is locked. When the centre differential locks, the VSC-OFF light in the combination meter illuminates to inform the driver that the VSC function has been turned OFF. The centre differential lock is designed for freeing the vehicle if it is stuck in mud for example, however it would be difficult for the vehicle to free itself if the engine output were reduced due to the operation of VSC. Therefore when the centre differential is locked, the VSC function is turned OFF.If a malfunction occurs in the VSC system, the VSC warning light illuminates to alert the driver. If the vehicle with VSC begins to oversteer or understeer because of an emergency avoidance measure, or by excessive speed in a corner, VSC will automatically activate. By adjusting the engine’s power output and braking each wheel independently, VSC helps to return the vehicle to a ‘zone of stable operation’..
