2021 McLaren Super Series 765LT Instruments and warning lights

The high-performance 2021 McLaren Super Series 765LT sports car has a complex set of instruments and warning lights that are meant to give the driver important information and alarms. Key information like speed, RPM, and fuel level are shown clearly on the digital instrument panel. Warning lights are placed in key areas to let the driver know about things like engine temperature, oil pressure, and battery health. The 765LT also has improved safety warnings for systems like traction control and brake fluid levels, as well as performance-focused displays like G-force meters and lap timers. This car’s instruments and lights are important for both the driving experience and the safety of the vehicle. They combine high-tech features with useful functions.

Warning lights

	Tyre pressure monitoring system (TPMS) Prior to every time the vehicle is to be driven, each tyre should be checked when cold and inflated/deflated to the inflation pressure recommended on the tyre pressure label. (If your vehicle has tyres of a different size than the size indicated on the tyre pressure label, you should determine the proper inflation pressure for those tyres). In certain circumstances it is possible that the tyre pressure monitoring system (TPMS) pressure warning will display without the loss of air from the tyre. This may be due to temperature variations between the locations where the tyre pressure was set and where the vehicle is driven. For example setting pressures in an air-conditioned or heated garage and then driving the vehicle outside may induce a tyre pressure warning after a short period of driving. The warning may also display when extreme ambient temperature variations occur or during seasonal temperature changes.
	Seat belt warning light Seat belts and child restraint systems are the most effective means of restraining vehicle occupants from impact forces, which minimises the danger of injury from interior impacts and the effects of whiplash. WARNING: A seat belt which is not worn, worn incorrectly, or has not been engaged fully in the seat belt buckle, cannot perform its intended function. To avoid injuries, ensure that all vehicle occupants wear their seat belt correctly at all times. Ensure that the belt:
	Rear fog lamp WARNING: The lights do not switch on automatically in foggy conditions. NOTE: The rear fog lamp only operates when the light switch is in position (A) or (2). Press the rear fog lamp button in the centre of the light switch. The rear fog lamp notification light on the Folding Driver Display and the light in the switch both illuminate.
	Supplementary restraint system (SRS) warning light Driver’s front air bag in the steering wheel Passenger’s front air bag in the upper area of the dashboard Side head air bags in the doors WARNING: Correct operation of the air bags can only occur if the steering wheel, the passenger’s air bag cover and the door trim are not covered. WARNING: Air bags are not a substitute for correctly worn seat belts, they enhance the level of occupant protection offered by seat belts. WARNING: To reduce the risk of injuries in the event of an accident, observe the following points: Ensure that the driver’s chest is at least 25 cm (10 in) from the air bag cover. Do not lean forward over the dashboard while the vehicle is in motion. Do not rest your feet on the dashboard. Only hold the steering wheel by the outside of the rim. You could be injured if the air bag deploys and you are holding the inside of the steering wheel. Occupants, particularly children, must not lean on the doors from inside the vehicle. Ensure that there are no other objects between the vehicle occupants and the deployment area of the air bags. Because of the high speed at which air bags deploy, there is a risk of injuries caused by an inflating air bag.

	Electronic stability control (ESC) Electronic stability control (ESC) monitors driving stability and traction between the tyres and the road surface. Electronic stability control detects when a wheel starts to spin or the vehicle starts to skid and stabilises the vehicle by braking individual wheels, and/or limiting the engine power output. This also assists when pulling away on wet or slippery road surfaces and stabilises the vehicle when braking.
	Engine warning
	Anti-lock braking system (ABS) The anti-lock braking system prevents the wheels from locking when you brake. This allows the vehicle to be steered during braking manoeuvres. The anti-lock braking system works from a speed of approximately 5 mph (8 km/h) upwards, regardless of road surface conditions. It works on slippery surfaces, even when you brake gently. WARNING: Do not depress the brake pedal repeatedly in quick succession (pumping). Depress the brake pedal firmly and evenly. Pumping the brake pedal reduces the braking effect. If the anti-lock braking system operates during braking, the warning light flashes, and the brake pedal pulses as this happens. When the anti-lock braking system is activated, maintain the force on the brake pedal until the braking situation is over.
	Brake warning light Brake-steer Brake steer offers the benefits of a torque vectoring differential, but is integrated into the braking system reducing weight and providing excellent speed of response. Torque vectoring gives the differential the ability to change the amount of power that is sent to each of the rear wheels to provide optimum stability and traction. If the system detects that the vehicle is starting to understeer through a corner, the inside rear brake is gently applied. This helps to increase the yaw rate of the vehicle, making the vehicle feel more resistant to understeer. The lateral ‘g’ force is also increased giving better handling characteristics. If the driver uses too much throttle exiting a corner, the inside rear wheel increases speed, which without brake steer could cause the vehicle to become unstable. In this situation, brake steer will again gently apply the brake on the inside rear wheel, thereby restoring traction and stability. NOTE: When parking on steep downhill slopes, turn the front wheels towards the kerb. When parking on steep uphill slopes, turn the front wheels away from the kerb. Parking brake status If the parking brake applied status light is flashing, the parking brake has failed to engage/disengage. To resolve, engage/disengage the parking brake again.
