Maintenance Engine Coolant
WARNING
Used engine oil may cause skin irritation
or cancer if left in contact with the skin
for prolonged periods of time. Used
engine oil contains chemicals that have
caused cancer in laboratory animals.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after
handling used oil.
Do not leave used engine oil within the
reach of children.
NOTICE
For Smartstream T-GDi engine
When the oil pressure is low due to
insufficient engine oil, the Engine Oil
Pressure (
) warning light will
appear.
In addition, the enhanced engine protec
-
tion system, which limits the engine's
power is activated and the Malfunction
Indicator Lamp (
) will illuminate
when the vehicle is driven in this state
continuously. When oil pressure is
restored, the Engine Oil Pressure warn
-
ing light will turn off and the engine
power will no longer be limited.
CAUTION
The engine oil is very hot immediately
after the vehicle has been driven and
can cause burns during replacement.
Replace the engine oil after the engine
oil has cooled down.
Engine Coolant
The high-pressure cooling system has a
reservoir filled with year round anti
-
freeze coolant. The reservoir is filled at
the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before travelling to a colder climate.
CAUTION
僅 When the engine overheats from low
engine coolant, suddenly adding
engine coolant may cause cracks in
the engine. To prevent damage, add
engine coolant slowly in small quanti
-
ties.
僅 Do not drive with no engine coolant. It
may cause water pump failure and
engine seizure, etc.
Checking the coolant level
WARNING
Removing radiator cap
僅Never attempt to remove the
radiator cap whilst the engine is
operating or hot. Doing so might
lead to cooling system and engine
damage. Also, hot coolant or steam
could cause serious personal injury.
僅 Turn the engine off and wait until it
cools down. Use extreme care when
removing the radiator cap. Wrap a
thick towel around it, and turn it coun
-
terclockwise slowly to the first stop.
Step back whilst the pressure is
released from the cooling system.
When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove it.
