Note
- Vehicle components such as the engine,
transm ission, suspension or electrical sys-
tem can be severely damaged by driving
through water.
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the eng ine off when dr iving through
water.
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely .
- Avoid d riving through salt water (corrosion).
Warming
up and cooling
down
By carefully warm ing up and cool ing down your
veh icle, you can he lp ensure that it is not over-
stressed un necessa rily during sporty driving.
When warming up, the vehicle is dr iven at a max-
imum eng ine speed of 6000 RPM in order to raise
the eng ine oi l temperature
to a min imum of
140 °F (60 °C). The tires a lso on ly reac h their full
road ho ld ing capability once they have warmed
up .
The cooling fan can continue to run in your vehi-
cle after the engine is swit ched off. Howeve r,
d riving t he vehicle to cool it dow n is particularly
important. During sporty dr iving, the engine and
brakes, the exhaust system, and the transmission
a ll become extremely hot . Before you park the
ve hicle, you shou ld drive it for a few m iles/kilo-
meters at light load in the low rpm range to al-
low it to cool down.

The catalytic converter is an efficient "clean-up"
device built into the exhaust syst em of t he ve hi-
cle. The catalyt ic conv e rter burns ma ny of the
po llutants in the exhaust gas before they are re-
leased into t he atmosphere.
The exclusive use of un leaded fuel is cr itically im-
po rt ant fo r the life of the catalytic converte r and
prope r funct io ning of the eng ine.
