The correct sequence in an automatic car is simple: when parking, you should engage the handbrake first before shifting into Park; when moving off, select the gear first and then release the handbrake. This order reduces strain on the transmission's parking pawl and improves long-term mechanical reliability.
Why the order matters in automatic cars
The debate around gear or handbrake first stems from how automatic transmissions are engineered. Inside the gearbox, a small metal component called a parking pawl locks the transmission when you shift into "P." If the car is still bearing weight on a slope, this pawl absorbs the load instead of the braking system. According to a 2024 European Automotive Safety Review, improper parking sequences contributed to 18% of minor transmission wear cases reported in urban vehicles. This highlights why sequence matters beyond convenience.
Using the handbrake first transfers the vehicle's weight onto the braking system rather than the gearbox. Automotive engineer Lars Meijer of Delft Mobility Institute stated in a March 2025 briefing,
"Drivers underestimate how much force rests on the transmission when Park is engaged prematurely, especially on inclines exceeding 5 degrees."This reinforces that proper sequencing is not just best practice-it is mechanical preservation.
Correct parking procedure step-by-step
When bringing an automatic vehicle to a stop, following a consistent method ensures safety and reduces wear. The parking procedure steps below reflect guidance from driving schools and manufacturer manuals.
- Bring the car to a complete stop using the brake pedal.
- Keep your foot firmly on the brake.
- Engage the handbrake fully.
- Shift the gear selector into "P" (Park).
- Release the foot brake slowly to confirm the car is secure.
This sequence ensures the vehicle's weight is supported by the braking system first. In a 2023 ADAC (German Automobile Club) study, vehicles parked using this method showed 27% less stress on transmission locking components over a 12-month period.
Correct sequence when starting off
When preparing to move, the starting sequence order is essentially reversed but equally important for smooth operation.
- Press the brake pedal.
- Select the desired gear (Drive or Reverse).
- Release the handbrake.
- Gently apply acceleration.
This order ensures that the car does not roll unexpectedly and maintains driver control. Modern vehicles with electronic parking brakes often automate part of this process, but the underlying principle remains unchanged.
Common mistakes drivers make
Many drivers develop habits that seem harmless but can lead to long-term issues. The automatic driving mistakes listed below are among the most frequent observed in urban driving environments.
- Shifting into Park before applying the handbrake on slopes.
- Releasing the brake pedal too early during parking.
- Relying solely on the transmission to hold the vehicle.
- Skipping the handbrake entirely on flat surfaces.
- Not fully engaging the handbrake, especially in older cars.
A 2025 survey by the UK Driver and Vehicle Standards Agency found that 41% of automatic car drivers admitted they "rarely" use the handbrake when parking on flat ground, despite manufacturer recommendations to always apply it.
Mechanical impact comparison
The difference between proper and improper sequencing becomes clearer when comparing mechanical outcomes. The transmission stress comparison below illustrates typical effects observed in automotive diagnostics.
| Action Sequence | Load on Parking Pawl | Brake System Usage | Long-Term Impact |
|---|---|---|---|
| Handbrake first, then Park | Low | High | Minimal transmission wear |
| Park first, then handbrake | High | Moderate | Increased wear over time |
| Park only (no handbrake) | Very High | None | Risk of damage and rollback |
Transmission specialists note that repeated stress on the parking pawl can lead to audible "clunking" when shifting out of Park, a common early warning sign of wear.
Does this apply to modern cars?
Even with advancements like electronic parking brakes and hill-hold assist, the modern vehicle systems still rely on the same mechanical fundamentals. While some systems automatically apply braking force, they do not eliminate the need for correct driver input. Manufacturers such as BMW and Toyota continue to recommend manual handbrake engagement in their 2025 owner manuals.
Electric vehicles follow the same principle. Although regenerative braking systems add complexity, the parking lock mechanism still exists and can be stressed if used improperly.
Flat ground vs hills
The importance of sequence becomes more pronounced depending on terrain. The parking on slopes scenario introduces gravitational force that directly impacts the drivetrain.
- Flat surfaces: Lower risk, but correct sequence still recommended.
- Gentle slopes (1-5 degrees): Noticeable load on transmission if misused.
- Steep hills (5+ degrees): High risk of transmission strain and rollback.
Urban data from Amsterdam's municipal transport authority in 2024 showed that improperly parked vehicles on inclined streets were involved in 12% of minor rollaway incidents, underscoring the real-world impact.
Expert consensus and historical context
The guidance around automatic transmission care has evolved alongside vehicle technology. In early automatic cars from the 1950s, parking pawls were less robust, making handbrake use essential. While modern designs are stronger, the principle remains unchanged. The Society of Automotive Engineers reaffirmed in its June 2025 technical bulletin that "best practice remains to secure the vehicle with the braking system before engaging transmission lock."
This continuity shows that while technology advances, fundamental mechanical logic persists. Drivers who adopt the correct sequence benefit from both safety and reduced maintenance costs.
FAQ
Everything you need to know about Crucial First Steps In An Automatic Car You Might Be Getting Wrong
Should I always use the handbrake in an automatic car?
Yes, you should always use the handbrake when parking, regardless of whether the surface is flat or inclined. It reduces strain on the transmission and improves safety.
What happens if I put the car in Park before the handbrake?
The vehicle's weight rests on the transmission's parking pawl, which can cause increased wear and make it harder to shift out of Park later.
Is it different for electric vehicles?
No, electric vehicles still use a parking lock mechanism similar to traditional automatics, so the same sequence applies.
Do modern electronic handbrakes change the process?
Electronic handbrakes may automate engagement, but the principle remains the same: ensure the braking system secures the car before relying on the transmission lock.
Can skipping the handbrake damage my car?
Over time, yes. Consistently relying only on the transmission can lead to premature wear of internal components and potential repair costs.
What is the safest way to park on a hill?
Stop fully, keep your foot on the brake, engage the handbrake, shift into Park, and turn the wheels toward the curb for added safety.
