TOYOTA SIENNA
When you see the various Sienna modified cars on the road, you may understand why the Toyota Sienna is so recognized by so many people. The Toyota Sienna has been regarded as one of the best choices for family MPV since it has not entered China yet.
01
Adequate space
The spacious seating space and abundant storage space are absolutely attractive for consumers who truly consider Sienna as "the second space of the family".
02
Sufficient fuel efficiency
The 2.5L dual-engine power of Toyota not only provides sufficient power, but also has excellent fuel economy.
03
Good brand reputation
For a car model that accompanies the family for more than ten years, the stability of quality is also valued by many consumers.
REASONS FOR MODIFICATION
01
Plastic feel of the interior
The original interior of the car has poor leather texture, with a single color and no design highlights.
02
The carpet is difficult to manage
The original car carpet is prone to various bacteria, and it is easier to manage after modification and upgrading.
03
Poor leather texture
The original interior of the car has poor leather texture, with a single color and no design highlights.
04
The button design is unreasonable
The central control screen requires physical button support, and the button area is insufficient. All three buttons are touch type, which is prone to accidental touches.

Crystal gear lever and buttons
The console is equipped with a crystal gear lever and buttons, with high texture and feel. The console retains the original car design style, with a hollowed-out bottom space, and is equipped with USB and TYPE-C interfaces for the driver and co-pilot. The interface is equipped with ambient lighting for convenient charging. The upper space is equipped with a larger storage space, and the storage box can be opened and closed with one click for easy use.
Atmosphere light
The atmosphere light is embedded in the door panels, dashboard, and console. There are three atmosphere lights distributed on the door panels, among which the top atmosphere light pattern is made by laser engraving, and the light guide strip emits light, which is uniform, with high texture. The bottom atmosphere light is embedded around the low speakers, the atmosphere light on the dashboard is distributed in the upper and middle positions, and there is a through atmosphere light on the co-pilot console. The atmosphere light group is controlled by five vehicle-grade modules, the main module transmits signals through Bluetooth, and the secondary module receives them, and the lighting is adjusted through the main screen. The atmosphere light adopts vehicle-grade electronic modules and Osram light beads (top in the industry), supporting 128 kinds of gradual color modes.
Cup holder/wireless charging
The co-pilot console is equipped with a water bottle holder and wireless charging. The water bottle holder is equipped with a clip to keep the water bottle stable. The wireless charging is compatible with all mobile phones with wireless charging function, which is convenient to use.
Sound system
Upgraded original car audio, increased power, and better sound quality!
CORE ADVANTAGES
The wiring harness is an important part of the vehicle's electrical system. It connects various electrical components of the vehicle, such as lights, audio, air conditioning, etc., and plays the role of transmitting electrical energy and signals. In the automotive modification market, the selection of wiring harness is one of the important assessment criteria for the stability of automotive electronics and the safety of the entire vehicle! The choice of inferior wiring harness often leads to problems such as functional failure of electronic components, spontaneous combustion of wires, short circuit of wires, failure of vehicle braking, and vehicle spontaneous combustion! Compared with ordinary wiring harness, vehicle-grade wiring harness has higher prices and better quality!
01
The vehicle-grade wiring harness has excellent temperature resistance. During the operation of the vehicle, there is a large temperature difference between the inside and outside of the vehicle. The vehicle-grade wiring harness can meet the normal operation requirements of the vehicle in a high-temperature environment and be more stable.
02
The vehicle-grade wiring harness has a high level of fireproof performance. The level of fireproof performance determines the burning degree and spreading speed of the vehicle-grade wiring harness in the event of a fire, and the vehicle-grade wiring harness will not burn by itself in a fire.
03
The skin material of the vehicle grade wiring harness has certain temperature resistance and flame retardant properties, which can ensure that the vehicle grade wiring harness will not cause accidents due to high temperature or fire during normal use.
04
The testing and testing standards for vehicle grade wire harnesses are higher, ensuring that the conductor materials of vehicle grade wire harnesses have high-quality conductivity and corrosion resistance, and the insulation layer has high-quality insulation and wear resistance; The wiring harness connection is more secure and reliable, eliminating problems such as poor contact or short circuits.
MODIFICATION FEATURES
Refrigerator
For this product, some space on the co-pilot console has been reduced, and a hot and cold refrigerator has been added to the vehicle, equipped with a control screen! The refrigerator uses a pressure-loaded refrigerator, which is powered by a compressor for cooling, with fast and strong cooling, and can reach -5°C for cooling and 55°C for heating, capable of making ice, preserving freshness, and controlling temperature in sections, which is not easy to damage. The inner liner of the refrigerator is made of pure aluminum parts, with a thermal conductivity coefficient of 300, which is faster than plastic parts in terms of heat conduction and cooling, and can ensure rapid heat conduction and cooling. It only takes 15 minutes to drop to below zero and freeze; in addition, the refrigerator is equipped with food-grade rubber. All parts of the refrigerator are controlled and tested using vehicle-grade standards, and high-level scheme standards are adopted.
Internal wiring harness of the entire vehicle
All built-in wiring harnesses adopt vehicle-grade standard wiring harnesses, with more than 80+ connectors. The production process adopts high-standard requirements, ensuring oil resistance, heat resistance, flame resistance, and abrasion resistance. The product quality is reliable. The installation and retracting process of the built-in wiring harnesses adopt strict assembly requirements, and will not use the loose buried wire method commonly used in the market. Therefore, it can be ensured that there will be no door panel noise during the long use cycle, and the wiring harness plugs all adopt original factory plugs, which have higher safety, strong plug pulling feeling, and better stability and endurance when subjected to external pulling force.
Peach wood trim
Using natural wood materials and using IML injection molding technology, the texture is excellent.
Door panel function buttons/sound insulation cotton
Door panel function buttons: can support multiple function adjustments, the seat can support heating, ventilation, and massage functions, the headrest, backrest, and seatcan support manual multi angleadjustment,and are equipped with memory function(According to the original car configuration)The car doors are made of high-quality soundproof cotton and welded using ultrasonic waves, which can fully reduce interior noise and resonance.
Vertical curved surface machine Wrapping
For this product, except for the dashboard which is covered by hand, the rest of the decorative kits are covered by machine. Traditional manual covering with a blow gun can easily cause uneven glue, and although the smoothness can be achieved in the short term, bulging may occur in the long term. Compared with manual covering, machine covering has more uniform glue activation through channels, followed by vacuum re-drawing after compression, and then secondary heating and secondary activation for compression. The compression efficiency is higher, the covered surface is more uniform, and it is more stable in the long term.
Environmentally friendly adhesive
All coverings are made of environmentally friendly glue. After the installation of the interior kit, there will be no odor, harmful substances, etc. in the vehicle, and the safety level is higher.
Airbag
For the safety airbag area, the wrapping material is cut and processed to a thickness of 50 threads, and the internal material is also weakened to a thickness of 70 threads. At the same time, rubber material is filled inside to maintain toughness. The safety airbag is rigorously tested to ensure safety and that flying objects will not cause damage to the human body when it is ejected.
