2024+ Land Cruiser - Tow/Haul Mode and Gear Selection

[J250Admin]

Towing a trailer with your Land Cruiser? Here's what you need to know about Tow/Haul mode and manual gear selection when hauling heavy loads. (Reference: Owner's Manual, pages 217, 229-230)

Safety Precautions (Owner's Manual)​

Critical Warnings for Towing:

• Don't ride the brakes or apply them too frequently while towing - the constant pressure builds heat and can reduce braking power when you need it most (Page 217)
• Due to the added load of the trailer, your vehicle's engine may overheat on hot days (at temperatures over 85°F [30°C]) when driving up a long or steep grade. If the engine coolant temperature gauge indicates overheating, immediately turn off the air conditioning (if in use), pull your vehicle off the road and stop in a safe spot (Page 217)
• To maintain engine braking efficiency and charging system performance, when using engine braking, do not put the transmission in D. If in the M mode, the transmission shift range position must be in 6 or lower (Page 217)
• Instability happens more frequently when descending steep or long downhill grades. Before descending, slow down and downshift. Do not make sudden downshifts while descending steep or long downhill grades (Page 217)
• Slow down before making a turn, in cross winds, on wet or slippery surfaces, etc. Increasing vehicle speed can destabilize the trailer (Page 217)
• Note that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the turn. Compensate by making a wider than normal turning radius (Page 217)
• Take care when passing other vehicles. Passing requires considerable distance. After passing a vehicle, do not forget the length of your trailer, and be sure you have plenty of room before changing lanes (Page 217)
• If the "M" indicator does not come on even after shifting the shift lever to M, this may indicate a malfunction in the automatic transmission system. Have the vehicle inspected by your Toyota dealer immediately (Page 230)

Tow/Haul Mode, Towing Procedures, Gear Selection, Manual Transmission, D-Position Steps​

What Tow/Haul Mode Does​

Use Tow/Haul mode when pulling a trailer or hauling a heavy load. Activating Tow/Haul mode optimizes engine, transmission, and steering to be more suitable for towing. Tow/Haul mode adjusts your engine and transmission to prioritize control and keep transmission temperatures in check while towing.

How to Activate​

1. Press the Tow/Haul button on your dashboard or steering wheel
2. The Tow/Haul indicator will come on (visible on your instrument cluster/multi-information display)
3. System is now active and optimized for towing

How to Deactivate​

1. Press the Tow/Haul switch once more to cancel the mode
2. The indicator will turn off and you return to normal driving mode

Automatic Deactivation​

Tow/Haul mode is automatically deactivated under these conditions:

• When the front-wheel drive control switch is in L4 (Low 4-wheel drive lock)
• When driving mode select or Multi-Terrain Select (if equipped) is selected

If you switch to Low range or activate other driving modes, Tow/Haul mode is automatically disabled. You will need to reactivate it if needed.

Manual Gear Selection​

D-Position Gear Steps (D1-D8)​

In addition to normal automatic operation, the 8-speed transmission offers D-position gear step selection (D1 through D8). This allows manual control of acceleration and engine braking while in the D position.

How to Use:

1. Shift transmission to D position (normal automatic mode)
2. Use paddle shift switches or shift lever to select specific gear step (D1-D8)
3. Display shows selected gear step on your meter/instrument cluster (D1, D2, D3, etc.)

What Each Gear Step Does:

• D1-D4: Lower gear steps provide greater accelerating force, stronger engine braking force, and higher engine revolutions (RPM). Better control on long descents.
• D5-D8: Higher gear steps provide standard fuel efficiency, reduced engine braking, lower engine revolutions (RPM), and better highway cruising.

Key Principle: Lower gear step (D1) = Maximum engine braking and acceleration. Higher gear step (D8) = Normal highway efficiency.

Automatic Deactivation in D-Position:

Gear step selection will automatically deactivate and return to normal automatic operation when:

• The vehicle comes to a stop (footbrake applied)
• The accelerator pedal is depressed continuously for more than a certain period of time
• The shift lever is shifted to a position other than D
• The paddle shift switch is pressed and held for an extended period
  
  To help ensure safety and driving performance, downshifting operation may sometimes be restricted. In some circumstances, downshifting may not be possible even when the paddle shift switch is operated. A buzzer will sound twice when this restriction activates.
  
  To return to normal D position automatic operation, the + paddle shift switch must be held down for a period of time.

M-Mode Manual Transmission Control (M1-M8)​

How to Enter M-Mode:

1. Shift the shift lever to the M position
2. Gears can now be selected by operating the shift lever or paddle shift switches

How M-Mode Works:

• The selected gear (M1 through M8) will be fixed and displayed on your meter
• The gear will not change unless you operate the shift lever or paddle shift switches
• The gear changes once every time you operate the control

M-Mode Benefits for Towing:

• Full control over which gear the transmission uses
• Ideal for towing when you want to maintain a specific gear for engine braking
• Allows downshifting for descending hills without losing control
• Prevents automatic upshifting if you want maximum engine braking on long grades

Automatic Gear Changes in M-Mode:

Even in M-mode, the transmission will automatically change gears in these situations to protect the engine and transmission:

• When vehicle speed drops (automatic downshift only) prevents stalling
• When the accelerator pedal is firmly depressed provides needed power
• When engine protection is needed: engine coolant temperature is low, automatic transmission fluid temperature is high or low, or other engine/transmission protection situations

M-Mode Speed Restrictions:

The gear will not shift when the vehicle speed is low, even if an upshift operation is performed. Choose a gear appropriate for your speed.

Real-World Tips from the J250 Community​

Pro Tips​

Activate Tow/Haul Mode Consistently

Always press the Tow/Haul mode button when towing. The J250 system will remind you to activate it if a trailer is plugged in. Develop a habit of enabling it every time you start the vehicle when towing.

Install a Weight Distribution Hitch (WDH)

Owners report that adding a weight distribution hitch made significant improvements in highway handling with loaded trailers. The J250 experiences light steering without a WDH, even with lighter trailer loads. This is worth the investment for safety and comfort.

Use Proper Trailer Brake Controller Setup

Install a trailer brake controller that automatically activates when the trailer is connected, rather than requiring manual settings activation. This prevents the safety issue of forgetting to enable brakes mid-trip.

Backup Practice Improves Confidence

Dedicate time to practicing backing up with your loaded trailer in an empty parking lot with cones. This builds muscle memory and prevents on-road mistakes that could damage vehicle or trailer.

Common Mistakes to Avoid​

Forgetting to Enable Tow/Haul Mode on Each Trip

The system doesn't remember your preference, so you must manually activate Tow/Haul each time you start the vehicle for towing. Without Tow/Haul mode, the transmission operates in standard mode, reducing engine braking efficiency and transmission cooling, potentially increasing heat buildup on long grades.

Neglecting Weight Distribution on Light Trailers

Thinking a weight distribution hitch is only needed for heavy trailers is a mistake. Even light trailers can exhibit highway instability (especially in crosswinds) if the hitch is not properly set up with weight distribution. Trailer sway at highway speeds can cause loss of control.

Excessive Speeding While Towing

Just because the Land Cruiser can reach highway speed limits doesn't mean you should while towing. Maintaining speed limit or slightly under is safer and more efficient. Higher speeds increase fuel consumption, reduce braking efficiency, and put more stress on transmission cooling.

Inadequate Braking Distance

Many new towers underestimate the braking distance required when pulling a trailer. Your vehicle-plus-trailer weighs substantially more and doesn't stop as quickly as an unloaded vehicle. Ensure sufficient spacing to prevent rear-end collisions.

Helpful Context from the Community​

How Tow/Haul Mode Works on the J250 Hybrid:

When Tow/Haul mode is enabled, the gas engine does not shut off at low RPM, and the electric motor barely activates in the low rpm range. This means the hybrid system prioritizes gas engine participation for better towing control and transmission cooling, deviating from fuel-economy optimization. This is a deliberate design choice for towing performance.

Realistic Fuel Economy Impact:

Owners report fuel economy dropping to approximately 19 MPG with Tow/Haul mode enabled while towing. This is a realistic expectation due to continuous gas engine operation, higher transmission fluid temperature requiring more cooling fan operation, and reduced aerodynamic efficiency with trailer attached. This is not abnormal for towing.

Official Towing Capacity Reality Check:

The J250 official towing rating is 6,000 lbs. This capacity is best suited for lightweight trailers and off-road towing (small camping trailers, motorcycle trailers), not heavy utility trailers or boat pulling.

Why J250 Uses Tow/Haul Mode Instead of S-Mode:

Traditional advice suggests using S (Sport) mode on older Land Cruisers when towing to lock the transmission in lower gears. However, the J250 uses Tow/Haul mode instead. Tow/Haul is specifically designed for towing and provides optimized engine braking AND transmission cooling; it's purpose-built rather than adapted. This is why the manual emphasizes using M6 or lower for engine braking on descents.
