Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as garage) which are not properly ven-
tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.

After a cold start, the automatic transmis-
sion shifts at a higher revolution. This al-
lows the catalytic converter to reach its
operating temperature earlier.

cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
