● Never loosen the bolts on wheel rims with bolted-on rings.
WARNING
If the wrong wheel bolts are used, the wheel bolt can loosen while driving and lead to loss of control of the vehicle,
serious accidents and fatal injuries.
● Always use wheel bolts that match the wheel rims and the vehicle type.
● Never use different wheel bolts.
● Use only two-piece wheel bolts on vehicles with two-piece wheel bolts.
After changing a wheel, the indicator lamp for the tyre monitoring system may indicate a fault in the system
(→ Tyre Pressure Loss Indicator) (→ Tyre Pressure Monitoring System).
Introduction
In some countries, the vehicle may be supplied with a breakdown set.
You can use the breakdown set to temporarily seal a tyre securely if it has been damaged by a foreign body or a
puncture up to about 4 mm (about 5/32 in) in diameter. Do not remove the foreign object, such as a screw, from the
tyre.
Once the sealant has been added to the tyre, the tyre pressure must be checked and adjusted again after
approximately 10 minutes of driving.
Seek assistance from a correspondingly qualified workshop if more than one vehicle tyre is damaged. The breakdown
set is only designed to fill one tyre.
Only use the breakdown set when the vehicle has been safely parked and you are familiar with the work and safety
precautions needed. Otherwise seek assistance from a suitably qualified workshop.
The tyre sealant must not be used:
—If the rim is damaged.
—If the outside temperature is below -20°C(-4°F).
—If there are cuts or punctures in the tyre that are larger than 4mm.
—If the vehicle was driven with very low tyre pressure or a flat tyre.
—If the use-by date on the tyre filler bottle has expired.
—If a foreign object has been removed from the tyre.
—In connection with mobility tyres. The word “Seal” is on the outer wall of the tyre if your vehicle is fitted with
mobility tyres.
WARNING
Use of the breakdown set at the side of the road can be dangerous.
If the vehicle and the working area are not secured appropriately, this can result in serious accidents and fatal
injuries.
● Use the breakdown set only if you are familiar with the necessary actions. If this is not the case, seek assistance
from a suitably qualified workshop.
● Stop the vehicle as soon as it is possible and safe to do so.
● Park the vehicle at a safe distance from moving traffic (→ In an emergency) (→ Parking).
● Make sure that the surface the vehicle is parked on is level and firm.
● All passengers, and children in particular, must be at a safe distance and away from your area of work.
● Switch on the hazard warning lights and set up the warning triangle to warn other road users.
● When using the breakdown set, never lift the vehicle with a jack, even if the jack is approved for the vehicle.
