226Vehicle careAutomatic transmission
fluidCaution
Extremely small amounts of
contamination can cause
automatic transmission damage
and cause it to not work properly.
Do not allow contaminates to
contact the fluid side of the
reservoir cap or from entering the
reservoir.
Automatic transmission fluid level
normally does not have to be
checked. To check the fluid level seek
the assistance of a workshop.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
