    I had this same problem after I replaced the alternator.

    Car wouldn't start initially, didn't seem to click over. It then seemed to run fine for approx. 1 week. Dash lights are now coming on, being the hand break light and battery light. I have stopped driving atm.

Hatterasnc,

You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.

Brake Light. Make sure you are not driving with hand brake on. Check brake-fluid level. Top off brake fluid if low and make appointment to check brakes. Driving with brake light can be dangerous; deal with this soon. Call tow truck or drive carefully and slowly to shop.
ABS (antilock brake system) Light. Indicates either low brake-fluid level, stuck brake caliper or faulty ABS. Check brake fluid and make appointment to get brakes checked. Call tow truck or drive carefully and slowly to shop.
Oil Light. Either engine is very low on oil or there is no oil pressure. Pull over and turn off engine immediately. Check oil level and add oil if low. Turn engine back on to see if light has gone off. If oil light is still on, bad oil pump (no oil pressure) is likely. Call tow truck.
Check Engine Light. Car's computer senses engine problem. Difference in performance may not be noticeable, but make appointment to have car diagnosed. This usually cost around $65-$75 to do. OK to drive. If problem is serious, computer may switch to limp-home (low-power) mode and you won't have option of waiting to bring car into shop.
Air Bag Light. Get air bags checked. Problem could prevent them from activating in accident. OK to drive, but not safe in accident.
Battery Charge Light. Alternator is not charging. OK to drive, but turn off any unneeded electrical devices (radio, heater, defroster) and avoid starting engine more than necessary. Bring car into shop soon to avoid getting stranded. When alternator is not charging, battery loses charge and car stops working.
Emissions Lights (O2 sensor, EGR, check emissions). Depending on car model, these lights may indicate problem with emissions sensor or may light up at certain mileage, usually 60,000 miles (100,000 km). Get sensors checked. OK to drive. If problem exists, car might get poor gas mileage.

Add Coolant to spherical reservoir at right rear of engine compartment as viewed from front. If it is low the coolant gauge flashing light will warn you of a low condition.

Air Bag Light, Brake Light, & ABS Light came on in the dashboard.


Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!

Sienna won't go out of park, warning lights lit after oil and coolant change


Check to see if your brake lights work(brake/ignition interlock), if they don't then the fuse that has blown may be the cause of the other warning lights in the dash, sure sound like they did something at the oil change place
