and
environment
Break-in
period
A new vehicle must be broken in, and the
break-in period should be 1,500 miles (2,500
km) . Do not use full acceleration for the first
600 miles (1,000 km) and do not exceed the
maximum engine speed of 6,000 rpm You
must also not use fu ll accelerat ion between
600 and 1,200 mi les (1,000 to 2,000 km).
From 1,200 to 1,500 mi les (2,000 to 2,500
km), you can gradua lly increase maxim um en-
gine speed to 8,250 rpm for brief periods.
During the first hours of operation, there is
greater friction in the engine and the trans-
mission than later when all the moving parts
have broken in.
The way you drive duri ng the first 1,500 miles
(2,500 km) affects engine quality. If you drive
at moderate engine speeds thereafter, partic -
ularly when the engine is cold, yo u reduce en-
gine wear and increase the potential mileage
of the engine.
Do not drive at RPMs that are too low . Shift
down when the engine is no longer running
"smoothly". Extreme ly high RPMs are gov-
erned automatically.
Driving
through
water
on roads
Note the following to avoid vehicle damage
when dr iving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
.&_
WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake roto rs and pads. Dry
t he brakes fi rst by braking carefully to re-
sto re the full braking effect.

Note
Vehicle components such as the engine,
transmission, suspension or electrical sys-
tem can be severely damaged by dr iving
through water.

Tips
- Check the depth of the water before d riv-
ing through it.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi-
cle to drive through safely .
- Avoid driving through salt water because
it can cause corros ion.
Catalytic
converter
You must use lead-free gasoline in your vehi-
cle, otherwise you will destroy the catalyt ic
converter.
Never run the fuel tank completely dry; their-
regular fuel supply could cause misfires . This
allows unburned fuel into the exhaust system,
possibly resulting in overheating and damage
to the catalytic converter .
.&_
WARNING
,-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in cont act with dry grass, brush,
fue l spills or ot her material which can
cause a fire.
- Do not apply addition al under coating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con-
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire.
