Before winter driving, what does the manual say to put in your windshield washer reservoir?

  1. A.
    Distilled water with a spoonful of salt
  2. B.
    Plain water topped up before each trip
  3. C.
    A cleaning solution that resists freezing Correct
  4. D.
    Engine antifreeze diluted with water
The Why

The answer is "A cleaning solution that resists freezing"

The manual tells you to fill the washer reservoir with a cleaning solution that resists freezing so the nozzles do not ice up in cold weather. Drivers who reach for choice D see the word 'antifreeze' on an engine-coolant jug and treat any product with that label as interchangeable across every fluid reservoir on the vehicle.

Why the others miss

The traps in the wrong answers

A. Distilled water with a spoonful of salt

Improvises a home remedy the manual does not describe. This answer reaches for a road-salt shortcut instead of the manufacturer-formulated fluid the manual expects.

B. Plain water topped up before each trip

Uses plain water in a system the manual expects to be freeze-resistant. This answer treats the washer reservoir like any household water bottle rather than as a spray system that has to work below freezing.

D. Engine antifreeze diluted with water

Substitutes engine cooling antifreeze for washer fluid. This answer assumes any product with 'antifreeze' on the label belongs in any reservoir, ignoring that engine coolant is toxic and not designed to be sprayed on glass.
