Can't find the battery in my 2006 530xi

No cabin filters under the seats

The cabin filter is on the passenger side,
in the engine compartment, under the plastic
wiper cowl cover

Remove the wiper arms,the push pins & wiper cowl

Those round filters under the seats, are for the
heated & cooled seat motors

Leave them alone they will be fine,don't get dirty

Hi

my knowledge about W210 (Sedan) and S210 (wagon)

Not really sure if other modles got the same location.

Battery located under the Right Back Passenger seat.

for the seadan ... you may have to remove the back seat by pressing the corner bottoms in both sides then left it up and drag it to front to got it free... you will see the battery under it.
for the wagon... open the back right door and release the bottom seat by pressing the lock handle at the side of the seat up.... seat bottom will be cimi free to be lifted to front and then you will have free access to the battery.


if you just need to recharch the low battery... you can find the charging plugs under the hood to the left side ( +) will be covered with black plastic box... open it and connect the possitive cable (red)... ( - ) will be few inches front of that to be conected with nigative cable (black)

1. Make sure you have the anti-theft codes for the radio and the navigation system, then write
down the frequencies for the preset buttons.
2. Tilt the steering wheel all the way up and telescope it all the way in.
3. '04-07 models passenger's seat: Carefully insert the tip of a small screwdriver (A) through
the hole in the back of the front seat belt lower anchor cover (B) and into the hole in the
front seat belt lower anchor (C). Unlock the lower anchor by pushing in on the screwdriver.
Remove the screwdriver, and then detach the front seat belt anchor plate (D) and anchor
cover from the lower anchor.4. Slide the seat all the way forward, then remove the seat track end covers from the back of both seat tracks.5. Slide the seat about half way to the rear so you can access the seat mounting bolts. If equipped with the driver's 8-way power seat, fully raise the seat.
6. If equipped with a side airbag, disconnect the negative cable from the battery, and wait at
least 3 minutes before removing the seat. 7. Remove the bolts securing the front seat. 8. Lift up the front seat, then detach the harness clip and disconnect the connector.
If equipped, the seat heater connector on the 2-way power seat and passenger's
manual seat. '04-07 models, disconnect the seat position sensor subharness connector on the
driver's manual height adjustable seat and the driver's 8-way power seat.
9. With the help of an assistant, carefully remove the front seat through the front door opening. 10. Install the seat in the reverse order of removal, and note these items:
Apply medium strength type liquid thread lock to the front seat mounting bolts
before reinstallation.
Make sure each connector is plugged in properly.
Tighten the seat mounting bolts to the specified torque in the sequence shown.
Slide the seat all the way back and tighten then slide it forward and
tighten Before attaching the lower anchor bolts, make sure there are no twists or kinks in
the seat belts. 04-07 models passenger's seat: The triangle marks on the anchor plate and
the lower anchor must face the same side. Insert the anchor plate into the lower
anchor, and make sure that it is locked securely. If equipped with a side airbag, reconnect the negative cable to the battery. Enter the anti-theft codes for the radio and navigation system, then enter the radio station presets. Reset the clock. Your all done. Drink a cold beverage and enjoy the rest of your weekend! hope this helps. Dave

In the 2006, the battery is under the front passenger seat.

To get to it is complicated -- from manual:


Move seat as far back as possible. Seat rails have covers on them - slide them forward....the left one will only slide forward, cannot be removed. Between the two seat rails you will see two little battery cover mounting nuts. Use 6 mm T-handle hex key to remove the nuts. Move seat as far forward as possible and twist rear rail covers to left and right and then pull toward rear of car. Pull back/fold floor carpet under seat from front to back (carpet is perforated so you may have to really yank the first time). There are two more battery cover mounting nuts between rear seat rails. There is a battery cover with an air vent pull it slightly to right and then lift out. There is a vent hose attached to battery on left side -- pull it out. Unfasten & remove attachment nuts on left side (low). Remove the battery attachment once those nuts are off. Push battery to the left. Disconnect battery negative lead (right) (do not let it touch pos. lead on left). Remove cover from pos (red/left) terminal and disconnect lead.

under the car at rear near gas tank, round can shaped filter.

what does a crown victoria look like?? none here in spain ,focus yes ,but knowing ford it uses the same parts so try lifting the back seat up and look for a big round plastic cover.My jaguar has ford name on a lot of components behinfçd the dash

Its on passenger side under rear seat cushion. Get in back seat FACING rear seatback, grab under lip of bottom seat cushion, and pull straight up. Disconnect seat heater connector (if so equipped) on passenger side and remove seat bottom. Tada! There ya go! Oh... btw. Its a $150 battery due to the venting system designed into it to vent fumes through a tube to the outside world. Thanks Cadillac!!! :(

Here's a quick check list for most common cost of SRS / Air bag problem.

Dirty contacts on driver and passenger seat belt buckles

Dirty contacts on seat belt connectors (under seats)

Dirty contacts on driver and passenger sides weight sensors (under seat)

Seat covers

Weight on passenger seat
(Example: grocery package trigger SRS / Air Bag light on the way home.)

I recommend you to pass an vacuum over the contacts and use CRC electronic parts cleaner to rule out connectivity problem.

I DO NOT recommend disconnecting the negative battery connector to clean the code(s).

Without the code(s) the dealer will takes "BILLABLE" time to reproduce the problem.

Hi...
Don't worry this happen everyday with some cars.
Is there a few places to locate the battery on cars up to date.

But on your 02 Lesabre. The BATTERY is located on:
Under REAR PASSANGER SEAT.
If you open one of the Rear DOORs you will need to remove the
Rear Back seat, after that you will see the BATTERY .

Remamber Under the Rear SEAT..

I hope this help on your problem.
Thank you for use fixya....

The battery should be under the front passenger seat. Move the seat forward as far as it will go, and you'll see a metal plate (may be under the carpet), which comes off with four Phillips screws. To actually get the battery out, you will need to remove the seat.
