If your Tacoma ends up in rising water, you have seconds to act. Not minutes. This is life-and-death information you hope you'll never need, but knowing these procedures could save your life.

(Reference: Owner's Manual, pg. 561)

What this guide covers:
  • The three escape scenarios and which one actually works
  • Why doors won't open (it's physics, not the truck)
  • Timing and what kills your escape window
  • The gear you should keep within reach

Submerged Vehicle, Underwater Escape, Flooded Car, Water Rescue, Window Escape​


Your Tacoma isn't designed to handle deeply flooded roads. If you see water across the road and can't judge the depth, turn around.

If you're already in rising water and the vehicle could flood or get swept away, get out now. Don't wait to see what happens.

How to Escape a Submerged Vehicle​


The Three Scenarios​


Scenario 1: Door Opens

Try your door immediately. If it opens, get out. Don't overthink this one.

Scenario 2: Door Won't Open, Window Will

Hit the power window switch right away. If the window goes down, climb out through it. This is your best escape route. Windows are easier to use than doors when water pressure builds.

Scenario 3: Both Door and Window Are Stuck

If water pressure has locked both the door and window, the manual describes waiting for the cabin to fill completely so pressure equalizes. Current automotive safety experts say this is dangerous advice. Full submersion takes too long and uses up your escape time.

What experts say: Popular Mechanics states: "That's nonsense...The escape needs to occur immediately. To reach equalization, the car would need to be completely submerged and filled with water." If your windows won't open, break them immediately with a window-breaking tool.

Context on the manual's guidance: Toyota lists pressure equalization as a last resort when nothing else works. This reflects older safety thinking that experts now consider too risky. Breaking the window and getting out immediately is the better approach.

Key Survival Principles​


  1. Move Fast in Rising Water
    Water pressure builds within seconds as your truck sinks. The first few moments are your escape window. Don't wait to see if things get worse.
  2. Windows Are Your Primary Exit
    Try power windows immediately. If they don't work, break the window with a tool (resqme, headrest, anything with a hard metal point). Get out through the window. It's your best shot.
  3. You Can't Fight Water Pressure
    Once water surrounds the truck, pressure against the doors can reach hundreds or thousands of pounds. You're not opening that door. Use the windows instead, and break them if you have to.
  4. Stay Calm
    Panic makes everything harder. Take one breath and work through the steps.
  5. Unbuckle Before Water Gets In
    Release your seatbelt immediately. Harder to unbuckle underwater when you're focused on not drowning.

Understanding the Timing​


Water Pressure Builds Fast:

Your biggest enemy is water pressure, not electrical failure. As water surrounds your Tacoma, pressure builds against doors and windows within seconds. This makes them nearly impossible to open mechanically, power or not.

Why You Can't Wait:

With just 2 feet of water outside, pressure against a door can exceed 350 pounds. Within 30-60 seconds of submersion, rising water pressure locks windows in place. The glass is pressed so hard against the frame that even power windows can't move.

Toyota's Official Guidance:

The manual doesn't specify how long electrical systems work underwater. Toyota's guidance is simple: get out immediately rather than counting on any timeframe for electronics to keep working.

Why Doors Won't Open (The Physics)​


The Pressure Problem:

When water surrounds your truck, it pushes against the outside of the door with hundreds or thousands of pounds of force. There's less pressure inside because the cabin hasn't filled yet. This creates a pressure differential. You can't overcome that force.

The Only Safe Solution: Exit Through Windows Immediately

Don't waste time trying doors. You have 30-120 seconds before complete submersion in most vehicles. Use power windows if they work, or break them with a tool. Get out through the window opening right away.

The manual describes waiting for pressure equalization as Scenario 3, but automotive safety experts say this takes too long and is too dangerous. The time needed for the cabin to completely flood uses up your escape window. Break the windows and get out instead.

Common Questions​


Q: Should I carry a window-breaking tool?

A: Yes, especially if you live in flood-prone areas or cross water regularly. A window-breaking tool (like a resqme device) gives you a backup if power windows fail. Keep it within easy reach of the driver's seat, not in the glove box or console where you can't grab it quickly in an emergency.

Q: How long before the truck sinks?

A: It varies wildly based on the vehicle, water conditions, and how you entered the water. General safety guidance suggests passenger vehicles float for 30-120 seconds, but this is highly variable. Don't wait to find out. Start your escape immediately when you hit water. Every second you wait reduces your options as water pressure builds.

Q: Can I break windows with my fist or elbow?

A: No. Side windows are made of tempered glass designed to resist impacts. Trying to punch or elbow through them will just injure you without breaking the glass. Use a window-breaking tool, the metal tip of a removable headrest, or a sharp metal object aimed at the window corner.

Q: What if I have passengers?

A: Help children and others unbuckle immediately. If windows open, strongest swimmers should exit first and assist from outside. If you're using the pressure equalization method, make sure everyone understands to take a deep breath before water reaches head level. Keep physical contact with young children throughout the escape. Don't separate from them.
