Engine cooling system
Coolant
The coolant provides cooling for the engine.
The percentage of the coolant additive deter
mines the freeze protection of the coolant in the winter.
The cooling system is sea led and generally re
q ui res little attention.
The cooling system has been filled at the fac
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture o f water and the man ufacture r's g ly
col-based coolant additive Gl3 ant ifreeze
w ith a nticorros ion add itives (50% for USA
models; 60% for Canad ian models). This mix
ture bot h assures the n ecessary frost protec-
Checkin g and fillin g 175
tion and protects meta l components in t he
engine's cooling system from corrosio n and
sca ling . It a lso raises the boiling point of the
coolant.
Do not reduce the concen tration of the cool
ant in the s ummer by adding p lai n wate r.
The
proportion of coolant additive must be at
least 50 % but not more than 60 %
to main
ta in antifreeze protect io n and coo ling eff ic ien
cy. If the coo la nt frost protection is too low,
t h e coolant could freeze and damage the vehi
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory fo r temperatures dow n to:
- -31°F( -35°C)USA
- -40 °F ( -40 °C) Canada .

(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli
mate condit ions. This is especially impor
t ant if you l ive i n a region where the win-
t er is extremely cold. If necessary, in-
cr ea se t he p ropo rtion of coo lant add itive

- Whe n ad ding coolant addi tiv e to yo ur

- We recommend using on ly coo lant ad
d itive Gl2 ++ or Gl3 (check the labe l)
for your vehicle. This coolant additive is ava ilable at authorized Aud i dea lers .
Othe r ty pes of antifreeze ca n sig nifi
ca ntly reduce cor ros io n protec tion . The
