HOWO's cab buttons include the clearance light and headlight switch, front fog light switch, rear fog light switch, emergency flasher switch, electric and air horn switch, axle lowering switch, axle data detection, inter-wheel differential lock, inter-axle differential lock, water level detection, and water level detection deactivation. Below are specific details about Sinotruk HOWO: 1. Introduction: HOWO is a model produced by Sinotruk Jinan Truck Co., Ltd., a subsidiary of China National Heavy Duty Truck Group, and is one of Sinotruk's flagship products. The Chinese certification for HOWO vehicles produced by Sinotruk is labeled as 'Haoluo,' but in spoken language, it is rarely referred to as such. In daily communication, people generally call it HOWO. HOWO is the English designation used primarily for export vehicles. 2. Usage Notes: Maintain proper lubrication oil levels, use differential locks correctly, and avoid severe overloading.
I've been driving trucks for over a decade, and the switch design on the HOWO model is quite reasonable. The turn signal switch on the left is crucial—push it up to activate the left turn signal and pull it down for the right turn signal, operating smoothly without any lag. The wiper switch on the right controls speed and the water spray function, ensuring safety during rainy drives. The headlight switch on the dashboard is a round knob—just a gentle twist adjusts between high and low beams, simple and intuitive, with a fog light button nearby. The air conditioning switch is straightforward too: the left knob for cold air, the right for warm air, and the fan speed control has high, medium, and low settings, allowing quick temperature adjustments while driving. The window switches are on the door handles—just a tap to raise or lower. There’s also a cruise control switch on the steering wheel, great for saving fuel and effort on highways. The reverse radar switch is in the instrument panel area, very handy for parking. Remember to regularly clean dust off these switches to avoid poor contact issues, and don’t get distracted by pressing them randomly while driving.
My HOWO truck is newly purchased, and the switch functions are very modern. The steering wheel integrates multi-function switches, with smooth turn signal operation—just a gentle push or pull. The right lever controls the wipers with variable speed and washer functions. The central control light switch is paddle-style, making it super convenient to switch between high and low beams during night driving, especially when paired with the automatic light mode for smarter operation. The air conditioning control area features buttons and knobs; temperature settings are easily adjusted with a twist, and the fan speed adjustment buttons respond quickly, with an additional air recirculation option to maintain fresh air inside. The window switches offer one-touch up and down for added convenience. Particularly cool is the cruise control switch located on the lower right side of the steering wheel, making long-distance driving much more relaxing. The rearview mirror adjustment switch is on the door armrest, with clearly marked buttons. These designs enhance driving focus. I recommend that beginners familiarize themselves with the layout by reading the manual to avoid accidental touches that could affect safety.
