Buick Enclave: Control of a Vehicle. Braking. Steering
Control of a Vehicle
Braking, steering, and accelerating are the three main actions that help a driver control a vehicle while driving. Each one must be used smoothly and at the right time. Sudden braking, sharp steering, or aggressive acceleration can reduce stability, especially on wet, icy, loose, or uneven road surfaces.
Maintaining control also depends on awareness. A driver should look far enough ahead, keep proper distance, hold the steering wheel correctly, and adjust speed before conditions become difficult. In the Buick Enclave, safe operation depends not only on vehicle systems, but also on calm, predictable driver input.
Good control begins before the trip starts. Make sure the seat, mirrors, steering wheel, and pedals are adjusted for a comfortable driving position. A driver who is properly positioned can brake, steer, and accelerate more accurately in normal driving and in emergencies.
Braking
Braking action involves both perception time and reaction time. Perception time is the time needed to recognize that braking is necessary. Reaction time is the time it takes to move the foot to the brake pedal and begin applying pressure.
Average driver reaction time is about three-fourths of a second.
In that time, a vehicle moving at 100 km/h (60 mph) travels 20m (66 ft), which can be a significant distance in an emergency. If the driver is tired, distracted, impaired, or following too closely, the stopping distance can become even longer.
Helpful braking tips to keep in mind include:
► Keep enough distance between you and the vehicle in front of you. More space allows more time to react and brake smoothly. ► Avoid needless heavy braking. Repeated hard braking can reduce comfort, increase wear, and may surprise drivers behind you. ► Keep pace with traffic while still maintaining a safe following distance. Driving too fast or too slow for the flow of traffic can create unnecessary risk.If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Pumping the brakes could make the pedal harder to push down. If the engine stops, some power brake assist will remain, but it will be used when the brake is applied.
Once the power assist is used up, it can take longer to stop and the brake pedal will be harder to push. Apply steady pressure to the brake pedal and guide the vehicle to a safe location if possible.
In normal driving, smooth braking is best. Begin slowing early when approaching traffic lights, stop signs, turns, congestion, or changing road conditions. Early braking gives passengers a more comfortable ride and gives other drivers more time to understand your intentions.
Wet or slippery roads require extra care. Allow more stopping distance and avoid sudden pedal movements. Even with modern braking systems, tire grip is limited by road conditions, tire condition, and vehicle speed.
Steering
Hydraulic Power Steering
Your vehicle has hydraulic power steering. It may require maintenance. See Power Steering Fluid. Proper fluid level and system condition are important for normal steering feel and reliable operation.
If power steering assist is lost due to a system malfunction, the vehicle can still be steered, but it may require increased effort. This can be especially noticeable at low speeds, while parking, or during tight turns. If steering effort changes suddenly, have the system inspected.
Variable Effort Steering
Some vehicles have a steering system that varies the amount of effort required to steer the vehicle in relation to vehicle speed. This feature is designed to make low-speed driving easier while helping the vehicle feel more stable at higher speeds.
The amount of steering effort required is less at slower speeds to make the vehicle more maneuverable and easier to park. This can help when turning into a parking space, backing out of a driveway, or moving through tight areas.
At faster speeds, the steering effort increases to provide a sport-like feel to the steering. This added effort helps support maximum control and stability when driving on highways or open roads.
If the vehicle seems harder to steer than normal when parking or driving slowly, there may be a problem with the system. You will still have power steering, but steering will be stiffer than normal at slow speeds.
See your dealer for service. A change in steering feel should not be ignored, especially if it is accompanied by noise, fluid leakage, vibration, or warning indicators.
Curve Tips
► Take curves at a reasonable speed. Entering a curve too fast can reduce control and may require sudden braking or steering correction. ► Reduce speed before entering a curve. It is safer and smoother to slow down before the turn rather than braking sharply while already in the curve. ► Maintain a reasonable steady speed through the curve. Smooth steering and steady throttle input help keep the vehicle balanced. ► Wait until the vehicle is out of the curve before accelerating gently into the straightaway. This helps maintain traction and gives the driver better control as the road opens up.Steering in Emergencies
► There are some situations when steering around a problem may be more effective than braking. A sudden obstacle, stopped vehicle, or road hazard may require a quick but controlled steering response. ► Holding both sides of the steering wheel allows you to turn 180 degrees without removing a hand. Keeping both hands on the wheel improves control during sudden maneuvers. ► Antilock Brake System (ABS) allows steering while braking. If ABS activates, continue to steer in the direction you want the vehicle to go while maintaining firm brake pressure.Emergency steering should be decisive but not excessive. A sharp overcorrection can cause loss of control, especially at higher speeds. Look where you want the vehicle to travel, steer smoothly, and avoid sudden repeated movements whenever possible.
The Buick Enclave is designed for comfortable family travel, but safe handling still depends on the driver. Smooth braking, steady steering, proper speed, and enough following distance are the foundation of safe operation in daily traffic and unexpected situations.
