With manual Saabs, a long time ago (if not still) you couldn't take the key out of the ignition unless the tranny was in Reverse. I never understood why, but the lowest-gear-to-prevent-rolling theory makes sense. [Maybe that's also why they had the ignition lock down on the console? Wacky Swedes]

This thread is a good reminder to get our e-brake cables checked/replaced, if necessary

Yep, all down to a guy not realising you NEED to use the parking brake when you park and especially on any sort of incline!! AND he has a license to DRIVE

Locked in reverse was as you say, it is the lowest gear so the least likely to roll. And with the amount of friction inherent in the goofy classic Saab drive train, it would take Mt. Everest grades to get an old Saab to roll in gear. Not so with the new ones though! Many Saabs in my past. I used to tell my Saab Club buddies that the only reason I bought Saabs was because I was too cheap to buy BMWs, but now I am older and make more money.

BTW, the whole "use your parking brake" business reminded me--make sure you keep your parking brakes in good order.
Someone told me a good way to do it was to, under controlled conditions (no traffic), use the parking brake (with just a click or two) to stop the car gently from say 30 mph. Anyone have any info on this?

I read that the SAAB ignition key on the floor was variously explained as designed so you don't hit the lock and keys with your knee in an accident, and to logically cluster all the starting controls -- ignition, parking brake and gearshift -- in the same place. They offered both explanations in the same sales brochure. One of my SAABs was one of the best cars I ever owned, and another one of the worst cars I ever owned and they were both the same model and even the same color! I gave up on SAAB after my indy threw in the towel and changed to Volvo marine. Both local SAAB dealers are no longer in business. I think a car can occasionally pop out of gear, or the handbrake can occasionally disengage, but the odds of both happening at the same time are fairly low. Since I'm not a lucky person, I use both.

You can probably test your parking brake function by trying to stop the car with it. But as a maintenance procedure I don't see what it is trying to achieve. |

No, this thread is a good reminder that most people with manuals don't understand the basic theory of operation.
I am sure BMW will use this thread to prove that R123456 must be replaced with PRND for basic consumer safety. You put the vehicle in gear when parked to support the parking brake. The parking brake does not support the gear to prevent rolling, it is the other way around. If the vehicle is more likely to roll backward due to slope then use first, if the vehicle is more likely to roll forward then use reverse. And make sure the e brake has been applied.

I'm not sure you can make the engine turn backwards......maybe if you stopped on a steep incline facing up and put it 2nd or 3rd...

and since prnd (auto) has entered the discussion, on an incline dont just rely on P to hold your car. Use the parking brake too.
Proper way is to set parking brake first then release foot from brake, THEN put in P. This ensures the weight isn't resting on the Park pawl inside the gearbox, because it can shear or break. When leaving, foot on brake, car in D, then release parking brake. |
