How to Activate Sport Mode in a CLS Class

Activating Sport Mode in your Mercedes-Benz CLS Class is a straightforward process, designed for intuitive driver interaction. While the exact location might vary slightly depending on the model year and specific trim level of your CLS, the principle remains the same. Most modern CLS models utilize a driving mode selection system accessible through either the gear selector stalk or the central infotainment display.

Here’s how you’ll typically engage Sport Mode:

Using the Gear Selector Stalk (Most Common)

This is the most direct and frequently used method for engaging driving modes in the CLS Class. You’ll find the selector stalk positioned on the right side of the steering column. It’s the same stalk you use to shift between Park (P), Reverse (R), Neutral (N), and Drive (D).

1. Locate the Gear Selector Stalk: On the right side of your steering column, you’ll find a lever.
2. Engage Drive (D): Ensure the transmission is in Drive (D) mode.
3. Push the Stalk Up for Sport Mode: To select Sport Mode (S), push the gear selector stalk upwards. Most earlier models will require a single push upwards from ‘D’ to engage ‘S’. Some newer models might have a dedicated button or a more elaborate digital selector.
4. Verify on the Dashboard: After you push the stalk, check your instrument cluster or the central display. You should see the selected mode displayed, typically as ‘S’ or ‘Sport’.
5. Returning to Comfort Mode: To revert to the standard Comfort Mode (C), you generally push the stalk downwards once from ‘D’. Some models might also have an individual mode or Eco mode accessible through further pushes or using buttons on the center console.

Using the Infotainment System (Some Models)

In some newer CLS generations or models equipped with advanced MBUX (Mercedes-Benz User Experience) systems, you might have the option to change drive modes directly through the central touchscreen or a dedicated control on the center console.

1. Navigate to the Vehicle Settings: On the main menu of your infotainment screen, look for an option related to “Vehicle,” “Driving,” or “Dynamic Select.”
2. Select Driving Mode: Within this menu, you should find different driving modes listed, such as “Comfort,” “Sport,” “Sport+,” “Eco,” and “Individual.”
3. Choose “Sport”: Tap on the “Sport” option to activate it.
4. Confirm: The system will usually confirm your selection, and the instrument cluster will update to show ‘S’ or ‘Sport’ mode is active.

Regardless of the method, the key is to ensure the ‘S’ or ‘Sport’ indicator is clearly visible on your dashboard. This confirms that your CLS Class is now set to deliver its ultimate driving power.

What Changes When You Engage Sport Mode?

Selecting Sport Mode in your CLS Class initiates a cascade of electronic adjustments designed to sharpen the car’s reflexes and enhance driver engagement. It’s a comprehensive transformation that affects multiple core systems. Here’s a breakdown of the primary changes you’ll experience:

Transmission Tuning

This is arguably the most noticeable change. The transmission control unit (TCU) is reprogrammed to behave more aggressively:

• Later Up-shifts: The transmission will hold gears longer before shifting up. This keeps the engine within its powerband, delivering more torque for quicker acceleration and maintaining higher revs for a more aggressive sound.
• Earlier Down-shifts: When you brake or decelerate, the transmission will downshift more readily. This prepares the car for re-acceleration, ensuring you have immediate power available and also utilizing engine braking for better control.
• Sharper Shifts: Gear changes themselves often feel more pronounced and quicker, providing a more direct sensation of power being transferred to the wheels.

Engine Mapping

The engine’s throttle response and power delivery are optimized for performance:

• Increased Throttle Sensitivity: The accelerator pedal becomes more sensitive. A smaller input will result in a larger throttle opening, making the engine feel more responsive to your commands.
• Boost Management (for turbocharged engines): Turbocharged engines may experience altered boost pressure management to deliver maximum power more readily.
• Engine Sound Enhancement: Many CLS models feature active exhaust systems. In Sport Mode, these systems often open up flaps or valves, allowing the engine to produce a deeper, sportier exhaust note, particularly under acceleration and deceleration.

Suspension and Damping (if equipped with adaptive suspension)

If your CLS Class is equipped with adaptive damping or an adaptive suspension system (like AIRMATIC or AMG RIDE CONTROL), Sport Mode often comes into play here as well:

• Firmer Damping: The suspension stiffens to reduce body roll during cornering, providing a more stable and planted feel.
• Lower Ride Height (on air suspension): Some air suspension systems will automatically lower the vehicle’s ride height in Sport Mode to reduce the center of gravity and improve aerodynamics.
• Improved Handling: The combination of firmer damping and potentially a lower stance significantly enhances the car’s ability to corner with precision and confidence.

Steering Calibration

The power steering system is often adjusted:

• Increased Resistance: Steering effort typically increases, providing more feedback from the road and a feeling of greater connection.
• Sharper Response: The steering may become more direct, meaning a smaller turn of the wheel translates into a more immediate change in direction.

Driver Assistance Systems

In some instances, even the behavior of certain driver assistance systems might be subtly adjusted to align with a sportier driving profile, though their core safety functions remain constant.

The cumulative effect of these changes is a vehicle that feels more alive, more responsive, and more eager to perform. It transforms the CLS from a comfortable cruiser into a capable sports sedan.

When to Use CLS Class Sport Mode

Sport Mode is a fantastic tool for enhancing your driving experience, but its optimal use depends on the situation. While it’s tempting to leave it engaged all the time, understanding when to select it will maximize its benefits and maintain the longevity of your vehicle.

Ideal Scenarios for Sport Mode:

• Spirited Driving on Winding Roads: When you’re on a scenic route with twists and turns, Sport Mode allows the CLS to take corners with greater composure and accelerates out of them more forcefully.
• Overtaking Maneuvers: For confident and quick overtaking on highways or two-lane roads, Sport Mode ensures you have the necessary power and responsiveness readily available.
• Performance Driving on a Track: If you’re participating in a track day or autocross event, Sport Mode is essential for extracting the maximum performance from your CLS.
• When You Desire a More Engaging Experience: Simply put, if you want to feel more connected to the road and enjoy a more dynamic drive, Sport Mode is the way to go, even for short periods.
• Downhill Driving (for controlled descent): The earlier downshifts can help utilize engine braking more effectively, reducing the reliance on your brakes when descending steep grades.

When to Avoid or Switch Out of Sport Mode:

• Heavy Traffic: The sensitive throttle and aggressive transmission shifts can make stop-and-go traffic jerky and less comfortable.
• Fuel Economy Focus: Sport Mode prioritizes performance, meaning it will consume more fuel than Comfort or Eco modes.
• Long Highway Cruises (standard driving): While Sport Mode can be useful for quick acceleration on the highway, for steady cruising, the standard Comfort Mode offers a smoother ride and better fuel efficiency.
• Driving with Passengers Who Prefer Comfort: If your passengers are sensitive to aggressive driving, the firmer ride and sharper shifts in Sport Mode might be less desirable.
• Unfamiliar or Slippery Conditions: The increased responsiveness and potentially firmer suspension can make the car less forgiving on wet, icy, or loose surfaces. It’s generally safer to stick to Comfort or even Eco modes in such conditions, allowing for more controlled power delivery.

By understanding these scenarios, you can use Sport Mode strategically to enjoy the best of both worlds: the refined luxury and comfort of your CLS Class when you need it, and its thrilling performance when you desire it.

Understanding the CLS Class Driving Dynamics: A Table

Mercedes-Benz vehicles are renowned for their sophisticated engineering, and the CLS Class is a prime example. The differences between the driving modes, particularly between Comfort and Sport, are designed to offer distinct driving experiences. Below is a table highlighting the key characteristics and how they change across typical CLS driving modes.

This table illustrates how Sport Mode transforms the CLS’s character. While Comfort Mode excels at providing a serene and luxurious journey, Sport Mode unlocks the car’s performance pedigree, making every drive more engaging and thrilling. Some CLS models may offer additional modes like Sport+ or Individual, which allow for even finer customization of these parameters.

The Technology Behind Driving Modes

The ability to switch between distinct driving personalities, such as Comfort and Sport, is a hallmark of modern automotive technology. Mercedes-Benz employs a sophisticated electronic system known asDYNAMIC SELECT (or similar branding depending on the model year) to manage these transformations. This system acts as a central orchestrator, communicating with various vehicle control units to alter the car’s behavior.

At the heart of DYNAMIC SELECT is a set of pre-programmed algorithms that dictate how key components respond to driver input and road conditions. These algorithms are developed by Mercedes-Benz engineers to achieve specific driving characteristics. Here’s a glimpse into the technologies involved:

• Engine Control Unit (ECU): The ECU dictates throttle response, fuel injection, ignition timing, and turbocharger boost pressure. DYNAMIC SELECT adjusts the parameters within the ECU for each mode.
• Transmission Control Unit (TCU): The TCU governs gear selection, shift speed, and torque converter lock-up. In Sport Mode, it’s programmed for more aggressive downshifts and later, firmer upshifts.
• Electronic Stability Program (ESP) & Traction Control: These systems can also be adjusted. In Sport Mode, they may allow for a greater degree of wheel slip or cornering yaw before intervening, providing a sportier driving feel while still maintaining a safety net. For a deeper understanding of ESP, this resource from the National Highway Traffic Safety Administration (NHTSA) offers valuable insights.
• Adaptive Damping System (ADS) or AIRMATIC Air Suspension: If equipped, these systems electronically adjust shock absorber stiffness or air spring pressure in real-time. DYNAMIC SELECT tells the ADS/AIRMATIC control module to stiffen the damping or lower the ride height, as discussed earlier.
• Electric Power Steering (EPS): The EPS system can vary steering effort and responsiveness electronically. Sport Mode usually increases the resistance and sharpens the steering ratio.
• Active Dynamic Engine Mounts: Some performance-oriented models feature engine mounts that can stiffen in Sport Mode, reducing engine movement and transmitting a more direct feel to the driver.
• Active Exhaust Systems: Electronically controlled flaps in the exhaust system open or close to alter the sound profile, becoming more vocal in Sport Mode.

All these systems work in concert, managed by DYNAMIC SELECT. When you select a mode, the system swiftly recalibrates each component to match the desired driving profile. This integrated approach is what allows the CLS to feel so different and adaptable, embodying Mercedes-Benz’s philosophy of “The Best or Nothing,” even down to the granular control of driving dynamics.
