Buick Regal: Starting the Engine
Place the transmission in the proper gear.
Caution: If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty.
Move the shift lever to P (Park) or N (Neutral). To restart the vehicle when it is already moving, use N (Neutral) only.
Caution: Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission.
Shift to P (Park) only when the vehicle is stopped.
Starting Procedure
1. With the Keyless Access system, the RKE transmitter must be in the vehicle. Press ENGINE START/STOP with the brake pedal applied. When the engine begins cranking, let go of the button.
The idle speed will go down as the engine gets warm. Do not race the engine immediately after starting it.
If the RKE transmitter is not in the vehicle, if there is interference, or if the RKE battery is low, the Driver Information Center (DIC) will display a message.
Caution Cranking the engine for long periods of time, by pressing ENGINE START/STOP immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold weather (below -18 ВєC or 0 ВєF), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there as you press ENGINE START/ STOP, for up to a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the button and the accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.
Stop/Start System
Warning: The automatic engine Stop/Start feature causes the engine to shut off while the vehicle is still on. Do not exit the vehicle before shifting to P (Park). The vehicle may restart and move unexpectedly.
Always shift to P (Park), and then turn the ignition off before exiting the vehicle.
The vehicle has a fuel saving stop/ start system to shut off the engine to help conserve fuel.
Auto Engine Stop/Start
When the brakes are applied and the vehicle is at a complete stop, the engine may turn off. When stopped, the tachometer displays AUTO STOP. When the brake pedal is released or the accelerator pedal is pushed, the engine will restart.
