It can be that the brake sensor is sticky/faulty and it is conflicting with the cruise control. (CC says go, brake says no). When these conditions occur, the car goes into safe mode and disables the cc.
It means that the computer has detected a fault code that needs attention. Unfortunately, it isn't possible to guess what the computer is trying to tell you until you connect a code reader.
what does it mean when the hi transmission tempture light come on in a 1999 jaguar xj8
It could possibly be your mass air flow sensor is dirty. Go to autozone and buy mass airflow sensor cleaner, take the sensor off the car right next to the air filter on the passenger side under the hood on the intake with a screw driver. Read the directions on the cleaner carefully, apply the cleaner to the sensor. The car may run rough for a few days then clear up and the restricted performance light should go off. If the restricted performance light doesn't go off and the car still runs rough take it to auto zone and have them put it on their computer free of charge and it will more than likely still say it is the mass air flow sensor, which means the sensor is bad and needs to be replaced. The cleaner is around ten dollars and the new sensor is about $160.00, but let the cleaner work it may feel like the car is falling apart after the sensor is cleaned but dont take any action unless the car still runs rough after a week to a week and a half.
There is a microswitch hidden in the latch mechanism. See my more detailed answer to similar question giving fix-it help! Good Luck! Cwd450

From Jaguar. The problem with all Jaguars is the lighting pack so if you get one from a breaker, get the light pack and wiring too.
Remove rear light unit cover in trunk. Turn bulb holder fastener 90 degrees counter clockwise and remove. Replace faulty bulb.
