The short answer
Before choosing a program at an automatic car wash, find out how that program moves your car, then open the owner's manual for your exact model, model year and market and follow the section written for that type of wash. The manual decides four things: whether the car may go through an automatic wash at all, which gear and parking-brake state to use, which preparation steps to take and in what order, and what a built-in car wash mode does for you. If the manual and the wash operator's requirements disagree, or you cannot tell which section applies, settle that before you pay for the program.
The condition that changes the answer most is how the car moves. The same vehicle can need different settings in a wash that pulls it along than in one where it sits still, and different models handle the same situation differently. Instructions from another car, another model year or another type of wash are not a safe substitute.
Terms you need
- Tunnel or conveyor wash: the car rolls on its own wheels while a conveyor pulls it forward through the brushes and dryers. The wheels must be free to turn.
- Portal, in-bay or rollover wash: the car is parked and stationary while a gantry moves back and forth over it.
- Car wash mode: a setting on some vehicles that switches several functions at once for washing. The functions vary by model, so treat each one as a separate item rather than assuming the mode covers everything.
- Automatic parking brake or brake hold: features that apply the brakes on their own when the car stops or is switched off. In a conveyor wash these can work against the conveyor, so manuals often tell you how to set them first.
Step-by-step: matching the program to the manual
1. Identify the exact vehicle and its finish
Note the model, model year, market and powertrain, and use the manual for that combination; the in-car or online manual for your build is the most reliable version. Check the paint and any wraps or special finishes first, because some finishes rule out automatic washing entirely. Stop here if the manual says the finish must be washed by hand.
2. Find out how the wash program moves the car
Read the signs at the wash or ask the attendant whether the program is a conveyor tunnel or a stationary portal wash, and what the facility requires of the driver, such as gear position, foot off the brake, antenna removed or mirrors folded. A single site can offer both types under different program names, so confirm the specific program you plan to buy.
3. Open the manual section that matches that wash type
Look for the car-washing chapter and any warnings linked from it. If the manual has separate instructions for tunnel and portal washes, use only the one that matches step 2. If it gives gear or brake instructions without saying which wash type they apply to, do not guess; consult the full manual section, the dealer or the manufacturer before using a wash where the choice matters.
4. List what car wash mode does, function by function
If the car has a car wash mode, write down each function the manual says it performs, for example closing windows, turning wipers off, folding mirrors or switching on air recirculation. Then compare that list with the manual's full preparation list. Anything the mode does not cover, such as gear selection, parking-brake settings, parking sensors or accessories, is still your job.
5. Prepare the car in the documented order
Do the preparation steps in the order the manual gives, because some steps depend on others. For example, a brake-hold feature may need to be switched off before you select a gear or turn the car off. Typical items include the rain-sensing wipers, mirrors, windows, roof racks and other accessories, parking sensors and any automatic emergency braking linked to them, ventilation, gear position and the parking brake. The step with the most consequence is matching gear and brake state to the wash type: brakes that apply on a conveyor, or a car free to roll in a stationary wash, is the mismatch to avoid.
6. Check before the wash starts
- The gear and parking-brake state match the manual's instruction for this wash type.
- Automatic braking features the manual tells you to change are off, and the instrument display confirms it where the car shows a status.
- Windows are closed, wipers will not activate, mirrors are folded and accessories are removed or secured as instructed.
- You know how the manual says to restore normal settings after the wash, including whether car wash mode switches off by itself.
How the instructions differ between models: Polestar examples
Polestar's manuals for three different models show why one checklist does not fit every car. Each example below applies only to the model, year and market stated.
2020 Polestar 1 (US manual), conveyor washes
For washes that pull the car forward on its rolling wheels, Polestar's US manual for the 2020 Polestar 1 sets out a specific sequence. It covers the rain sensor, mirrors and accessories, the settings for stationary braking and the automatic parking brake, selecting N (neutral), and switching the engine off by holding the start knob for at least two seconds. Follow these steps in the manual's order. This sequence applies to that model and that type of wash, not to stationary washes or other Polestar models.
2026 Polestar 2, tunnel versus portal washes
The 2026 Polestar 2 manual, in the edition reviewed here for the Israeli market, gives separate instructions for the two wash types. For a tunnel wash, it specifies N without the parking brake applied, so the car can roll with the conveyor. For a portal wash, where the car stays still, it specifies P, which applies the parking brake. The same manual also covers the rain sensor, mirrors, parking sensors and their automatic braking, closed windows, secured accessories and air recirculation. The same car needs opposite brake states depending on the program, which is why step 2 comes before anything else.
2027 Polestar 4 (Hong Kong manual), finish and car wash mode
The Hong Kong manual for the 2027 Polestar 4 says matte paintwork must be washed by hand, so for a matte car the program decision ends at step 1. For other finishes, the manual lists car wash mode's functions as closing the windows, switching the wipers off, folding the mirrors and activating air recirculation. Gear position is not on that list. The manual includes both P and N instructions, so read that section in full to see which applies to the wash type you are using rather than borrowing the Polestar 2 split.
Hyundai and other brands with car wash mode
Hyundai owners, including those with a 2026 Palisade, searching for car wash mode should use the same method: open the car-washing and car wash mode sections of the manual for that exact vehicle, list the functions the mode performs, and handle every remaining step yourself according to the instructions for your wash type. The Polestar instructions above do not transfer to a Hyundai or any other brand, even where the feature has the same name.
A matching worksheet
Fill in one row per wash program. If a facility offers two programs that move the car differently, give each its own row and look up the manual instructions for each separately.
| Item | What to record |
| Vehicle | Model, model year, market, powertrain, manual version |
| Finish restrictions | Paint, wrap or trim that limits or rules out automatic washing |
| Wash program | Program name and whether the car is pulled on its wheels or stays stationary |
| Manual section | The specific instructions for that wash type |
| Preparation steps | Each step in the manual's order |
| Car wash mode | Each documented function, listed separately |
| Remaining manual actions | Steps the mode does not perform, including gear and parking brake |
| Facility requirements | What the operator requires of the driver |
| Unresolved conflicts | Any disagreement or missing instruction to settle before washing |
Illustrative example: one site, two programs
Suppose a wash offers an express tunnel and a touch-free in-bay program, and the car's manual has separate tunnel and portal instructions. The tunnel row would use the manual's conveyor branch, including its gear and parking-brake setting; the in-bay row would use the stationary branch. If the manual covered only one of the two, the other program would stay unresolved until the dealer or manufacturer clarified it. Neither row should borrow a neutral, parking-brake, wiper or locking instruction from another car or the other program.
When to skip the automatic program
- The manual says the finish, such as matte paint, must be hand washed.
- The operator's required gear or brake state contradicts the manual's instruction for that wash type.
- The manual gives gear or brake instructions but you cannot tell which wash type they belong to.
- You cannot switch off a feature the manual says must be off, or the car shows a warning you do not understand. In that case ask the dealer or manufacturer, or choose a hand wash.
