What is the Start-Stop Function of the Santana?

[VanVanessa]

The Santana's start-stop function involves equipping the engine with an enhanced motor that has an idle start-stop capability, allowing the engine to shut off and stop working when the vehicle meets the conditions for idling stop. Taking the 2021 Santana Automatic Comfort Edition as an example, its body dimensions are: length 4475mm, width 1706mm, height 1469mm, with a wheelbase of 2603mm, a fuel tank capacity of 52.8 liters, and a trunk capacity of 466 liters. The 2021 Santana Automatic Comfort Edition features a MacPherson strut front suspension and a compound torsion beam rear suspension. It is powered by a 1.5L naturally aspirated engine, delivering a maximum horsepower of 112 PS, a maximum power of 82 kW, and a maximum torque of 145 Nm.

I've been commuting with my Santana for two years, and the start-stop function is the configuration that automatically shuts off the engine at red lights. The temporary engine hibernation can save some fuel costs, especially in stop-and-go city traffic. However, it's important to note that it won't activate if the engine temperature hasn't risen or when the air conditioning is on. Also, the frequent starts do come with a noticeable jolt. If you want to temporarily disable it, there's a button with an 'A' on the lower left of the steering wheel—pressing it will display a yellow indicator on the dashboard. This function places high demands on the battery, and the factory equips it with a specialized start-stop battery. When replacing it, don't skimp by buying a regular one.

As an auto mechanic, I often encounter customers asking about the start-stop system. The Santana's system is quite sensitive. The engine shuts off when the brake is fully depressed, and it immediately restarts with a slight lift of the pedal. However, it's important to turn it off in advance when driving through water, as an automatic restart after stalling could be disastrous. Some experienced drivers worry it damages the starter, but manufacturers have actually reinforced its design. What's noticeable is that the automatic air conditioning temporarily interrupts cooling during startup, which can be felt as reduced airflow from the vents during long summer traffic lights.

I remember when helping a friend pick up their Santana two years ago, the salesperson specifically demonstrated the start-stop feature. The engine basically won't stop when the air conditioning is on, and the function is automatically disabled when the battery is insufficiently charged. The most useful aspect of this configuration for beginners is that it helps cultivate anticipation awareness—gently braking in advance when approaching a red light prevents the start-stop from triggering. If the battery has ever been undercharged, it's advisable to visit the 4S shop for an ECU reset; otherwise, the system might misjudge the battery level and refuse to shut off the engine.

Here's a little trick for driving a Santana with start-stop system: When encountering a short red light of about ten seconds, lightly press the brake to keep the car creeping, and the system won't shut off the engine. It can indeed save about 8% fuel consumption in urban driving, but I manually turn it off when the air conditioning is on in summer or when the heating is insufficient in winter. Note that setting the air conditioning temperature too low can affect the start-stop trigger frequency. If you want to save fuel, raising the temperature by two degrees is actually more cost-effective.

The start-stop system is most vulnerable to the installation of substandard electrical devices. For instance, a neighbor's Santana experienced system malfunctions after installing a $30 dashcam. Voltage fluctuations may trigger the start-stop warning light on the dashboard, which signals it's time to check the battery life. While the initial activation does consume more power than regular ignition, manufacturers have reinforced the starter with bronze bushings, so durability isn't a major concern. The most practical benefit comes during morning rush hour traffic jams, where it can cumulatively save you enough money for half a cup of milk tea.
