The 5-speed automatic transmission models have been added instead of the 4-speed automatic transmission models.
The SR5 grade of the regular cab model with the 2UZ-FE engine has been discontinued, and base grade 2WD and 4WD models have been added.
2. Exterior
The design of the headlights has been changed.
The design of the rear combination lights of the regular and access cab models has been changed.
Two types of newly designed, 16-inch aluminum wheels have been added.
The following exterior colors have been added:

3. 1GR- FE Engine
The 1GR-FE engine has been added instead of the 5VZ-FE engine.
4. 2UZ-FE Engine
The VVT-i (Variable Valve Timing-intelligent) system has been newly adopted to improve fuel economy, engine performance, and reduce exhaust emissions.
The ACIS (Acoustic Control Induction System) has been newly adopted to enable the engine to produce a higher power output.
Air injection system is newly adopted. This system uses an electric air pump for pumping air from the electric air pump to exhaust port of the cylinder head. This ensures the proper warm-up performance of TWC when starting a cold engine condition.
The tail pipe emission regulation has been changed from the ULEV to LEVII-ULEV (California), and Tier2 Bin8 (except California).
The fuel tank has been changed from steel to multi-layer plastic to comply with the LEV-II evaporative emission regulations.
The fuel filler pipe has been changed from steel to stainless steel to comply with the LEV-II evaporative emission regulations.
The evaporative emission control system has been changed in order to comply with the LEV-II evaporative emission regulations.
5. Clutch
A newly developed clutch has been adopted for the 1GR-FE engine model.
6. Manual Transmission
A newly developed RA60 6-speed manual transmission has been adopted for the 1GR-FE engine models.
7. Automatic Transmission
On the ’05 Toyota Tundra, the A340E and A340F 4-speed automatic transmission have been changed to the A750E and A750F 5-speed automatic transmission [Super ECT (Electronically Controlled Transmission)].
8. Propeller Shaft
Along with the changes made to the engine and transmission, rear propeller shafts with different lengths have been newly adopted.
9. Differential
The differential gear ratio is as follows:

2UZ-FE 3.916
1GR-FE 3.769
4WD
2UZ-FE 3.909
10. Brake
A newly developed hydraulic brake booster with built-in the skid control ECU has been adopted for the brake control system with VSC (Vehicle Stability Control) as optional equipment.
Semiconductor wheel speed sensors have been adopted for the front and rear speed sensors of the models with VSC.
The CAN (Controller Area Network) communication system has been adopted for the brake control system with VSC.
11. Tire Pressure Warning System
A newly developed tire pressure warning system with the tire pressure warning system reset switch has been adopted.
12. Steering
The construction of the intermediate shaft has been changed by splitting it into two portions, one in the gear box and the other in the steering column, which are joined with a sliding yoke. As a heat shield measure, a heat insulator has been added to the rubber coupling.
13. Power Steering Vane Pump
A new power steering vane pump has been adopted for the 1GR-FE engine model.
Along with the recent adoption of the 1GR-FE engine, the mounting position of the power steering reserve tank and the pipe routing have been changed.
14. Seat
Newly developed seats have been adopted for the front seats on all models.
A headrest has been added to the center rear seat of the access cab model.
15. Seat Belt
A 3-point ELR (Emergency Locking Retractor)/ALR (Automatic Locking Retractor) seat belt has been added to the center front seat of the regular cab model.
A 3-point ELR/ALR seat belt has been added to the center seat of the 40/60 split front seat.
A 3-point ELR/ALR seat belt has been added to the center rear seat of the access cab model.
16. MPX (Multiplex Communication System)
CAN (Controller Area Network) communication has been adopted in the brake control system of the vehicles equipped with the VSC system.
17. Combination Meter
On the ’05 Toyota Tundra, a newly designed combination meter has been adopted.
All lights and indicators have adopted LEDs (Light Emitting Diodes).
An oil replacement reminder light has been adopted.
A step motor type movement has been adopted.
18. Air Conditioning
On the ’05 Toyota Tundra, all models use the air conditioning control panel unit (air conditioning amplifier integrated) to control the air conditioning compressor.
Along with the introduction of the 1GR-FE engine, a new type of compressor has been adopted.
19. Navigation With AV System
A new type of navigation system has been adopted. The navigation ECU has been integrated in the audio head unit, the screen has been redesigned for ease of viewing, and new functions have been added.
20. SRS Airbag
On the driver seat of all models and front passenger seat of separate seat models in the ’05 Toyota Tundra, a no-contact type seat belt buckle switch and a passenger occupant classification system have been adopted. In addition, a dual-stage SRS airbag system has been adopted for the driver and front passenger.
