230 Checking and filling
Checking the engine oil level
Fig. 185 Disp lay: o il level indica tor
• Park your vehicle on a level surface.
• Shut the engine off when it is warm.
• Switch only the ignition back on.
• Wait approximately two minutes.
• Select:
ICARI function button> (Car)* sys­
tems
control button > Servicing & checks >
Oil level.
• Check the oil level in the display c::> fig. 185.
Add engine oil if the bar of the oil level indi­
cator is near "min"
c::> page 230.
Depending on the way the vehicle is driven
and the operating conditions, oil consumption
can be up to 1/2 quart per 600 miles (0.5 liter
per 1,000 km) . Consumption may be higher
within the first 3,000 miles (5,000 km).
@ Tips
The oil level indicator in the MMI Display is
only an information display. If the oil level
is low, a minimum oil warning appears in
the instrument cluster. Add oil
c::> page 230. If the hood has been opened,
the current oil level is shown in the instru­
ment cluster the next time the ignition is
switched on .

A discharged batte ry can fre eze at tempera­
tures of on ly 32 F
0 (0 °C). A llow a frozen bat­
tery to thaw completely befo re attempt ing to
charge it¢
A . Howeve r, we recommend not
using a thawed battery again because the bat­
tery cas ing can be cracked d ue to ice forma­
tion and can leak battery acid.
Batt ery charging (Ma ximum charging rate
of 30 amp s/14 .8 Volt)
When charging at low voltages (e.g . w ith a
tr ickle ch arger ), the battery cables do not
have to be d isconnected first. The battery
caps should
not be opened when charging a
battery .
It is not necessary to remove the battery from
the luggage compartment, and it is also not
necessary to disconnect the cables .
Fast charging the battery (ch arging rate
a bo ve 14 .8 V olts)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery.
A WARNING
--Charging a battery can be dangerous .
-Always follow the operating instructions
provided by the battery charger manu­
facturer when charg ing your battery .
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out f irst .
- Do not reuse batteries wh ich were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated area. Keep away from open flame or elec­
tr ica l spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive .
- To reduce the danger of explosion, never
connect or d isconnect charger cab les
while the charger is ope rat ing .
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent techn ic ian wi th the proper equip­
ment .
- Battery acid that may sp ill dur ing cha rg­
ing should be washe d off wi th a solut ion
of wa rm water and baking soda to neu ­
tralize the ac id.
(D Note
Neve r use a fast charger as a booster to
start the eng ine. Th is w ill seriously dam­
age sensit ive e lectronic components, such
as contro l units, re lays, radio, etc., as well
as the battery charger.
