Which fluids can be refilled to or replaced in the vehicle engine?


1) Motor oil

Motor oil is a lubricant used in internal combustion engines, which power cars, motorcycles, lawnmowers, engine-generators, and many other machines. In engines, there are parts which move against each other, and the friction wastes otherwise useful power by converting the kinetic energy to heat.

2) Engine coolant

A coolant is a substance, typically liquid or gas, that is used to reduce or regulate the temperature of a system. An ideal coolant has a high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.

3) Brake fluid

Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible.

4) Windshield washer fluid

Windshield washer fluid (also called windshield wiper fluid, wiper fluid, screen wash (in the UK), or washer fluid) is a fluid for motor vehicles that is used in cleaning the windshield with the windshield wiper while the vehicle is being driven.

What is the minimum tread depth of summer and winter tires? What is the international designation for the winter tire?

Summer Tires

The minimum tread depth of the summer tire is 1.6 millimeters and must be valid throughout the tire circumference.

Winter Tires

The minimum tread depth of the winter tire is 4.0 millimeters and must be valid throughout the tire circumference.


The given minimum depths are valid only in the territory of the Czech Republic. In other countries, it may be different.

International designation of Winter Tires

To meet the demands of all drivers, 3PMSF marking has been introduced (Three Peak Mountain Snow Flake) which is an easily recognizable symbol that features a snowflake with three peaks in the background. This is the only marked element that confirms the actual winter parameters of a tire. Models with this marking are suitable for demanding weather conditions and retain their performance at temperatures below zero. The 3PMSF symbol is standardized and controlled by EU authorities, guaranteeing that the product meets the conditions of rigorous testing and is suitable for operation in difficult weather conditions.

Is a tire with "M+S" marking suitable for all conditions?

The answer is: not necessarily. So, what does the "M+S" marking mean? "Mud + Snow"- is only a declaration from the manufacturer that the product operates in mud and snow better than regular models. This may be misleading. You will also find "M+S" letters on some all-season tires. In general, "M+S" tires should have very soft rubber compound and a tread with more incisions to ensure better performance in the snow. Unfortunately, these features are not verified by standardized tests and may be unreliable.

What are the most common reasons for replacing a tire?

1) Tire defect

Any mechanical damage to the tire. This means for example puncturing, tearing, splintering, etc.

2) Worn tread

If the summer tire has a tread of fewer than 1.6 millimeters and a winter tire of fewer than 4.0 millimeters, it must not be used.

3) Tire lifespan

If you drive a typical number of kilometers, somewhere around 20,000-25,000 kilometers annually, a tire's tread will wear out in three to four years, long before the rubber compound does. But if you drive much less than that, or have a car that you only drive on weekends, aging tires could be an issue.

1 - Keep five years in mind


After five years or more in use, your tires should be thoroughly inspected at least once per year by a professional.

2 - Ten years is a maximum

If the tires haven't been replaced 10 years after their date of manufacture, as a precaution, We recommend replacing them with new tires. Even if they appear to be in usable condition and have not worn down to the tread wear indicator.
This applies to spare tires as well.

3 - Proper care expands a tire’s lifespan


You can increase your tire's longevity by maintaining the correct air pressure, performing regular tire rotations and vehicle maintenance.

4) Season

In the Czech Republic, the winter and summer seasons apply according to the Road Act. The winter period begins on November 1st and ends on March 31st. It is, therefore, necessary to use winter tires during this period.

How often and where is the driver required to bring the vehicle for technical inspection?

The deadline for technical inspection can be divided into two categories. 

First inspection

Within a period of 4 years from the date of registration of the vehicle in the register of road vehicles.

Further inspections

Periodically within 2 years from the date of the previous technical inspection.

Where to bring the vehicle?

The vehicles should be brought to the station of technical inspection (STK - stanice technické kontroly) that looks similar to a car repair shop. At this station, the technician will complete the vehicle inspection. However he is not authorized to make any repairs. The vehicle must be in good technical condition.

How to find out when the vehicle should be checked?

There is a red round sticker on the rear registration plate of the vehicle. This sticker highlights the year and month when the vehicle must be taken to the STK.

The exact date can be found on the large vehicle registration certificate, on the back side.

When can the driver use the hazard warning lights?

The Road Act allows the use of warning lights primarily in two cases.



If your vehicle has any fault and you are forced to stop in places where you are threatening traffic on the road or where it is forbidden. Attention. Warning lights must not be abused by the driver if he wants to stop, for example, where there is a prohibition on stopping because it is more comfortable for him.

Emergency Braking

In some cases, for example, on a highway where the speed of vehicles is much higher than usual, the driver can use the warning lights if he is suddenly forced to brake quickly. This gives information to drivers behind him to start braking also.

Warning lights are never used when parking. Always use directional lights when parking.

Name the exterior lighting of the vehicle.

Front lights​

daytime running lights  -  side lights  -  low beams  -  high beams  -  fog lights  -  indicators

Rear lights​

tail lights  -  fog lights  -  indicators  -  brake lights  -  reversing lights  -  registration plate lights​

Name the Integrated Rescue System phone numbers.

150 - firefighters​

155 - ambulance

158 - Czech state police

112 - the European Emergency Number

Name the mandatory equipment of the vehicle.


Warning (hazard) triangle


A warning triangle is an equilateral (equal-sided) triangle of around 600mm in size made of red reflective material. It can be put on the side of the road by anyone to warn other drivers of a breakdown or crash ahead.


Reflective (safety) vest


A safety vest is an article of personal protective equipment that's designed to have high visibility and reflectivity. A safety vest wearer is easily detected, which can help other parties avoid colliding with the individual. The reflective vest must be located in the vehicle so that the driver reaches it without having to leave the vehicle. For example under the seat.


First aid kit


A first aid kit is a collection of supplies and equipment that is used to give medical treatment.

Spare tire


A spare tire is an additional tire carried in a motor vehicle as a replacement for one that goes flat, a blowout, or other emergencies.



A jack or jackscrew is a mechanical device used as a lifting device to lift heavy loads or to apply great forces. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). 


Wheel nut (lug) wrench


A lug wrench is a name for a type of socket wrench used to loosen and tighten lug nuts on automobile wheels. 

Lug wrenches may be L-shaped or X-shaped. The form commonly found in car trunks is an L-shaped metal rod with a socket wrench on the bent end and a prying tip on the other end. The prying tip is mainly intended to remove hubcaps or wheel covers that may be covering a wheel's lug nuts. Another common type, sometimes called a spider wrench, is made in the shape of a cross with different sized sockets on each of the four ends.


Spare bulbs and spare fuses are no longer required.
Pre-Drive checklist


Check weather report and ensure that you are taking the proper outerwear (in case of breakdown)

Visual inspection of Tires, Check pressure if in doubt

A physical check of Gas Cap

Ensure windows provide clear visibility (scrape that ice and snow off, you should always have an Ice Scraper in your car!)

Visual inspection of headlights

Visual inspection of taillights

Check Oil level

Check radiator fluid level

Check brake fluid level

Check washer fluid level

Test turn signals

Test brake lights

Check back seat or rear passenger area through the windows before entering the vehicle

Start the car and check fuel on the Gas Gauge

Start the car and check for any “trouble lights”

Start the car and listen for odd noises (with radio OFF). 

A pre-drive check can be as simple as walking around the car to look at your tires and verifying the amount of fuel in your tank via the Gas Gauge before leaving. It might be the difference between making it to your destination or walking to find assistance.
