2015 VOLKSWAGEN PASSAT Red oil light

WARNING
To reduce the risk of serious personal injury when starting and running the vehicle's engine:
x Never start the engine or let it run in a confined or enclosed area. Engine exhaust contains carbon monoxide, a poisonous, colorless, and odorless gas. Carbon monoxide can cause unconsciousness and death.
x Never start the engine or let it run if oil, fuel or other flammable substances are under or around or have leaked from the vehicle, for example as a result of vehicle damage.
x Never leave the vehicle unattended with the engine running and especially when it is in gear. The vehicle could move suddenly or some other unexpected event could occur, result-ing in property damage, fire or personal injury.
x Never use starting assist fluids. Starting fluids can explode and can cause a “run-away” vehicle condition.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot. They can cause fires and serious personal injury.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Never apply additional undercoating or rust proofing on or near the exhaust manifold, exhaust pipes, catalytic converter, diesel particulate filter, or heat shields.
Warning and indicator lights

Brakes coated with road salt also react slower and need longer stopping distances. If there is salt on the roads and you are not braking regularly, brake carefully and gently from time to time to remove any
salt coating from the brake discs and pads ⇒ .
Brake disc corrosion (rust) and dirt build-up on the brake pads are more likely to occur if the vehicle is not driven much or is driven only for short distances with little braking. If the brakes have not been used and there is some rust on the discs, clean the brake discs and pads once in a while by carefully braking a couple of times while driving at relatively high speed to help clean the brake discs and pads.
Make sure nobody is behind you and that you do not endanger yourself or others ⇒ .
Brake system malfunction
If you brake and find that vehicle doesn't brake nearly as well as it used to (sudden increase in stop-ping distance), a brake circuit may have failed. The brake warning light H or "2!+% will come on and a message may appear in the instrument cluster display. If you believe the vehicle is safe to drive, immediately take it to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for repair. Drive slowly and very carefully, allow for the longer stopping distance, and be ready to push longer and harder on the brake pedal to slow the vehicle down.
Brake booster
The brake booster works only when the engine is running. It increases the force on the brakes above and beyond the pressure put on the brake pedal by the driver.
If the brake booster is not working, or if the vehicle has to be towed, you will have to push the brake pedal harder to make up for the lack of booster assistance and the resulting longer stopping distance
⇒ .
WARNING
New brake pads do not provide maximum braking performance.
x New brake pads do not have the best stopping power for the first 200 miles (320 km) and must be “broken in.” You can compensate for the slightly reduced braking force by putting more pressure on the brake pedal.
x Drive with extra care while the new brake pads are being broken in. This reduces the risk of collisions and serious personal injuries due to a loss of control over the vehicle.
x Never follow other vehicles too closely or put yourself into other situations that might require sudden, hard braking, especially when the brake pads have not been broken in.
WARNING
Overheated brakes will reduce the vehicle's stopping power and increase stopping distances considerably.
x When driving downhill, the brakes have to work especially hard and heat up quickly.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could over-heat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
x A damaged front spoiler or a non-standard spoiler can reduce airflow to the brakes and make them overheat.

Adjust the tire pressure
The proper tire pressure helps reduce rolling resistance as well as fuel consumption.
When purchasing new tires, always make sure that the tires are optimized for lower rolling resistance.
Use low viscosity engine oil
Fully “synthetic,” low viscosity engine oils that expressly comply with Volkswagen oil quality standards reduce fuel consumption. Low viscosity engine oils reduce the frictional resistance on the engine and are distributed more evenly and quickly, particularly when cold-starting the engine. The effect is partic-ularly apparent in vehicles that frequently travel short distances.
Always ensure the right engine oil level is maintained and keep to the scheduled service intervals (engine oil changes).
Make sure the engine oil that you purchase expressly complies with Volkswagen oil quality standards and is the oil approved by Volkswagen for your vehicle.
Avoid unnecessary weight
The lighter the vehicle, the more economical and eco-friendly it will be. For example, an extra 220 lbs (100 kg) of weight increases fuel consumption by up to 1 pint per 60 miles (0.3 l/100 km).
Remove all unnecessary items and unnecessary dead weight from the vehicle.
Remove unnecessary aftermarket components
The more aerodynamic the vehicle, the less fuel it will consume. Aftermarket components such as bicycle racks reduce its aerodynamic performance.
Therefore, remove unnecessary structures and unused rack systems, particularly if planning to drive at higher speeds.
