New brake pads
Remember t hat new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometres) after they
are in stalled.
New brake pads have to be "burnished in" before they have optima l
grab=> & .
During the break -in period, you should avoid putting severe loads
on the brakes. Severe loads include, for example, sudden hard
braking, in particular at very high speeds or, for example, on moun -
tain passes.

WARNING
Until the y develop the maximum "bite " for best stoppi ng powe r,

driving . You can comp ensat e for thi s by pressing t he brake pedal
more fi rmly. This appl ies w henever new pads are inst alled. •

Dri v ing a nd e nvironm e nt
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of t he vehicle . The cataly t ic converter burns many
of the pollutants in the exhaust gas before they are re leased into the
atmosphere.
The exclusive use of un leaded fuel is critica lly important for the life
of the catalytic converter and proper functioning of the engine.

WARNING
• Do not park or operate th e vehicle in areas whe re the hot
exha ust syst em may com e in conta ct wi th dry grass, brush, fuel
spill or other mat erial which can cause a fire.
• Do not apply additi onal undercoat ing or rustpr oofing on or
near the exhaust manifold, exhaust pipe s, cat alyti c convert er or
heat shields. During driving, th e subst ance used for undercoating
could overheat and cause a fire.

• Do not exceed t he correct engine oil level => page 224 .
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire . Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat .
• Do not turn off the igni t ion wh ile the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fue l can reach t he cata lytic converter. This could resu lt
in overheating of the converter, requiring its replacement .
