Preparation
If you get a flat tire, try to brake the car immediately without losing control.
Park your car away from the roadway on a level, horizontal area, preferably with a hard surface.
If necessary, turn on the hazard warning lights and place a warning triangle on the roadway in front of the parking space.
Set the parking brake and shift the transmission to first or reverse gear (manual transmission), or to position "P" (automatic transmission).
Support the wheel diagonally opposite the one to be replaced with wedges (in extreme cases, a couple of stones of sufficient size will do).
If the surface of the site is soft, place something like a piece of board under the heel of the jack.
Procedure execution order
1. The spare wheel and tools are stored in a special well in the trunk of the car. Turn back the mat and remove the cover panel. Remove the jack and tools from the well. Release the lock, take out the spare wheel and place it under the threshold of the car near the wheel to be replaced.
2. Use a screwdriver to pry off the decorative cap of the wheel to be replaced, thereby providing access to the mounting bolts. In the case of cast wheel disks, decorative caps are removed using a special key, usually included in the standard tool kit.
3. Using a wheel wrench, loosen the wheel bolts by half a turn. If any of the bolts do not give in, do not try to move them by standing on the handle of the wrench - contact a tire shop for help.
4. Place the jack in the appropriate jacking point near the broken wheel and make sure that its heel rests on a hard surface. Rotate the handle until the heel of the jack rests firmly on the ground. Make sure that the jack head is securely fixed in the groove of the threshold.
5. Raise the vehicle until the tire is off the ground. If the tire is flat, make sure there is enough space to install the inflated spare tire.
6. Unscrew the mounting bolts, remove the wheel and, having swapped it with the spare tire, place it under the car threshold near the jacking point.
7. Install the spare wheel and secure it with the bolts, tightening them with moderate force using a wheel wrench. Lower the car to the ground, remove the jack and finally tighten the wheel mounting bolts in a diagonal order. Replace the wheel cover.
In conclusion
Remove the chocks from under the wheels.
Place the tool and the removed wheel in their proper places.
Check the inflation pressure of the spare tire installed to replace the flat tire. If you do not have an accurate pressure gauge at hand, drive the car at a slow speed to the nearest service station, where you can check the pressure.
Take the punctured wheel to a tire shop for repair as soon as possible.
At the first opportunity, re-tighten the wheel mounting bolts to the required torque.
