checked.
XMake sure that the air supply to the engine radiator is not blocked, e.g. by
snow, slush or ice.
XDo not start the engine again until the coolant temperature is below 248 ‡
(120 †). Otherwise, the engine could be damaged.

Rthey may wear excessively and/or unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steering and braking, may be greatly
impaired.
There is a risk of an accident.
