Important!
Tire pressure differs by approx.
0.1 bar/1.5 psi per 10° C/18° F of air
temperature change. Keep this in
mind when checking tire pressure
inside a garage — especially in the
winter.
Example:
Room temperature = approx.
+ 20° C/ + 68° F
Ambient temperature = approx.
0° C/ + 320 F
Adjusted air pressure = specified air
p 0.2 b a r/+ 3 psi.
Tire temperatures and pressure
increase with the vehicle speed. Tire
pressure should therefore only be
corrected on cold tires. Correct tire
pressure in hot tires only if pressure
has dropped below the data listed in
the table and the respective operating
conditions are taken into considera­
tion.
Engine Oil Level Check
1 Dipstick
2 Oil filler cap
Check engine oil level regularly or
after each fuel fill-up, with the engine
off and at operating temperature
(engine must be at operating temper­
ature for some time).
The vehicle should be parked
g on level ground and the oil
level must be somewhere
between the lower and the
S
upper mark on disptick (1);
do not add in excess of the
upper mark.
Wipe dipstick before any oil level
measurement. To determine the oil
level, check both sides of the
dipstick. Always determine the oil
level by means of the straight
horizontal marking formed by the oil
on one side of the dipstick.
