Avoid
damaging
the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam-
aged.
This is especially true for vehicles with low-
slung chassis (sports chassis) and fully loaded
vehicles .
Driving
through
water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any highe r tha n the
bottom of the vehicle body.
- Do not d rive faster than wa lking speed.
_&
WARNING
After d riving through wate r, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re-
store the full braking effect.
(])
Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys -
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv-
ing through it.
- Do not stop the veh icle, 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 thro ugh salt water because
it can cause corrosion.

trol system (catalytic converter) is function-
ing properly to ensure that your vehicle is run-
ning in an environmentally sound manner.

r::;> page 183, Adding engine oil~-
.. Never try to push- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean-
up" dev ice built into the exhaust system of
t he vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be -
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert-
er and prope r funct ion ing of the engine.
A
WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con-
verter or heat sh ields. During driving, the
substance used fo r undercoating could
overheat and cause a fire.
(D
Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converter .
- Do not exceed the correct engine oil level
¢page 183 .
- Do not drive until the fuel tank becomes
completely empty . The engine could mis-
fire. Unburned fuel could also get into
