Vehicle Controls

Before you can drive safely you must know your vehicle inside and out. The K53 vehicle controls section tests your knowledge of every instrument, warning light, switch, and pedal in the car. Understanding what each control does — and when to use it — is not only a test requirement but a core safety skill. This guide covers all the controls you need to know for the South African learners and driving licence tests.

Dashboard Instruments

The instrument cluster is the panel of gauges and displays directly in front of the driver. Check these before and during every journey.

• Speedometer — shows your current speed in kilometres per hour (km/h). Always monitor it to ensure you stay within the speed limit. In South Africa the outer scale is km/h; some vehicles also show mph on an inner scale — always use km/h.
• Tachometer (rev counter) — shows engine speed in revolutions per minute (RPM). Used to judge when to change gear. A petrol engine is typically most efficient between 2 000 and 3 000 RPM for normal driving. The red zone (usually above 6 000–7 000 RPM) indicates dangerous over-revving.
• Fuel gauge — indicates how much fuel remains in the tank. The "E" mark means empty (reserve); "F" means full. Never allow the gauge to fall to the red zone — running out of fuel on a freeway or at night is dangerous.
• Engine temperature gauge — shows coolant temperature. The normal operating range is in the middle of the gauge. If the needle moves into the red or "H" (hot) zone, pull over safely and switch off the engine immediately to avoid serious damage.
• Odometer — records total distance driven (cannot be reset). The trip odometer (if fitted) can be reset to measure individual journey distances and is useful for calculating fuel consumption.
• Gear indicator — on automatic vehicles, shows the selected gear range (P, R, N, D, etc.). On manual vehicles some modern cars display the recommended gear.

Warning Lights

Warning lights illuminate in the instrument cluster when the vehicle's systems detect a fault or unsafe condition. Never ignore a warning light — some require immediate action.

• Oil pressure warning (oil can symbol) — red light. Indicates critically low oil pressure. Stop safely as soon as possible and switch off the engine. Driving with low oil pressure can destroy the engine within minutes.
• Battery / charging warning (battery symbol) — red light. The electrical charging system is not working. The battery may soon go flat. Drive to the nearest workshop without delay.
• Brake warning light (exclamation in circle) — red light. Illuminates when the handbrake is applied, or when brake fluid is low, or when there is a brake system fault. If it stays on while driving with the handbrake released, check brake fluid and have the system inspected immediately.
• ABS warning light — amber/yellow. The Anti-lock Braking System has a fault. Standard braking will still work but the ABS will not activate in an emergency. Have it checked.
• Engine management light / Check engine (engine symbol) — amber. The engine or emissions system requires attention. The vehicle may still be driveable but should be taken to a workshop promptly.
• Engine temperature warning — red. Engine is overheating. Stop immediately and allow the engine to cool. Do not open the radiator cap while the engine is hot.
• Fuel low warning (fuel pump symbol) — amber. Usually illuminates when approximately 10–15 litres remain. Refuel at the next opportunity.
• Airbag / SRS warning — amber. The supplemental restraint system has a fault. Airbags may not deploy correctly in a collision. Have it inspected.
• Tyre pressure warning (TPMS) — amber. One or more tyres are significantly under-inflated. Check pressures when safe to do so.

Steering Column Controls

The stalks and switches mounted on the steering column control several essential functions. You must be able to operate them without looking away from the road.

• Indicator (turn signal) stalk — push up to indicate right, push down to indicate left. The indicator cancels automatically after turning. Always signal at least 3 seconds before turning, changing lanes, or pulling over.
• Headlight stalk — rotates or pushes through positions for park lights, low-beam headlights, and high-beam headlights. Pulling the stalk toward you flashes the high-beam (headlight flash to warn oncoming traffic or signal overtaking intent).
• Wiper stalk — controls windscreen wiper speed (off, intermittent, slow, fast) and typically also activates the windscreen washer when pushed forward or pressed. Rear wiper controls are usually on the same stalk or nearby.
• Hazard lights switch — usually a red or orange triangle button on the centre of the dashboard or steering column. Activates all four indicators simultaneously to warn other road users of a hazard or breakdown. Do not use hazards while driving in normal rain — this is dangerous and illegal.

Pedals

In a manual (stick-shift) vehicle there are three pedals; in an automatic, two. From left to right:

• Clutch (left pedal — manual only) — disengages the engine from the gearbox so you can change gears. Press fully before selecting a gear and release slowly and smoothly to avoid stalling or jolting. Never ride the clutch (keeping it partially depressed while driving) as this causes premature wear.
• Brake (middle pedal) — slows and stops the vehicle. Apply progressively and smoothly. In an emergency on a vehicle without ABS, pump the brake rapidly to prevent wheel lock. On a vehicle with ABS, apply firm, continuous pressure and let the ABS do the pumping automatically — you will feel a pulsing through the pedal, which is normal.
• Accelerator (right pedal) — controls engine power and therefore speed. Press gently for smooth acceleration. Release to engine-brake when slowing down. Never rest your foot on the accelerator when not accelerating.

Always use your right foot for both the brake and accelerator. Never use your left foot on the brake in any vehicle — this leads to unintended simultaneous braking and acceleration.

Mirrors

Mirrors are your eyes behind and beside the vehicle. Adjust all mirrors before moving off — never adjust them while driving.

• Interior (rear-view) mirror — gives a view through the rear window. Adjust so the entire rear window is visible without moving your head. Switch to the anti-dazzle (night) position in dark conditions to reduce glare from headlights behind you.
• Left side mirror — shows the left lane and the area alongside the rear of your vehicle. Adjust so you can see a sliver of your own vehicle on the inner edge and the road surface at the bottom.
• Right side mirror — same principle as the left. Essential before any right turn, lane change to the right, or overtaking manoeuvre.
• Blind spots — the areas not covered by any mirror (typically rear-left and rear-right). Always perform a physical shoulder check (look over your shoulder) before changing lanes, moving off from the kerb, or merging. The K53 driving test awards marks for every correct blind-spot check.

The K53 observation routine for mirror use is: interior mirror — side mirror — blind spot check — then act. This sequence must become automatic.

Lights and Indicators

• Park (side) lights — low-intensity lights at the front and rear used to make the vehicle visible when parked in a poorly lit area. Not bright enough for driving at night.
• Low-beam headlights — the standard headlights used when driving at night or in poor visibility. They illuminate the road ahead without blinding oncoming drivers. Switch on at dusk and in rain, fog, or dust.
• High-beam headlights — brighter and aimed further ahead. Use only on dark roads with no oncoming traffic. Dim to low beam when an oncoming vehicle is within 150 m or when following another vehicle closely. Failure to dip headlights is a traffic offence.
• Fog lights (front) — mounted low on the bumper; cut through mist, fog, and heavy rain better than headlights. Use only in poor visibility; do not use in clear conditions as they dazzle other drivers.
• Rear fog light — a single bright red light that makes your vehicle more visible from behind in thick fog. Switch it off when visibility improves.
• Indicators — flash amber to show your intended direction of travel. Always indicate before turning, changing lanes, overtaking, or pulling away from the kerb. Signal early enough to give other road users time to react.

Handbrake (Parking Brake)

The handbrake locks the rear wheels (on most vehicles) and keeps the car stationary when parked. It operates mechanically, independently of the foot brake, so it still works even if the hydraulic braking system fails.

• When to apply — whenever the vehicle is stationary for more than a moment: at traffic lights (optional but good practice), when parked, and before performing an incline start. In the K53 driving test, failing to apply the handbrake when parked will result in a failure.
• How to release — press the button on the top of the lever (or pull the lever up slightly first on some designs), then push the lever down while pressing the button. Release smoothly — jerking the handbrake off on a slope can cause the vehicle to roll.
• Testing the handbrake — with the vehicle on a slope, apply the handbrake, select neutral, and release the foot brake. The vehicle should remain stationary. If it rolls, the handbrake requires adjustment.
• Electronic parking brake — newer vehicles have an electronic button instead of a lever. Press or pull the button to engage, press it again while pressing the foot brake to release. The principle is the same.
