Break-in period
A new vehicle must be broken in, and the break-in per iod 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 eng ine speed of 6,000 rpm You
must also not use fu ll acce lerat ion between
600 and 1,200 mi les (1,000 to 2,000 km).
F rom 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 ho urs of operation, there is
g reater friction in the engine and the trans­
mission than later when a ll the moving parts
have broken in.
The way yo u drive duri ng the first 1,500 miles
(2,500 km) affects engine quality. If you drive
at moderate engine speeds thereafter, partic ­
u lar ly when the engine is cold, yo u reduce en ­
g ine 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 b rake roto rs and pads. Dry
t he brakes fi rst by bra king carefully to re­
sto re the full braking effect.
-
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrical sys­
tem can be severe ly damaged by dr iv ing
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 .
- Avo id driving through salt water because
it can cause corros ion.
Catalytic converter
You must use lead-free gasoline in your veh i­
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,
poss ibly resulting in overheating and damage
to the catalytic converter .
.&_ WARNING ,-
-Do not park or operate the vehicle in
areas where the hot exha ust system may
come in co nta ct with dry g rass, brush,
fue l spills or o ther material which can
cause a fire.
- Do not app ly addition al under coating or
r u stproofing on or nea r the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
