Fluid Topping Up

Coolant
Coolant is a mixture of water and
antifreeze/corrosion inhibitor. Only check
the coolant when the vehicle is positioned
on level ground and the engine is cool.
Topping Up The Coolant
WARNING: The coolant system is
pressurised. Only unscrew the cap
when the engine is cool. You could
be scalded by hot escaping coolant if
you unscrew the cap whilst the
engine is warm.
WARNING: Coolant is highly
flammable. Fire, naked flames and
smoking are prohibited when
handling coolant.
WARNING: Coolant is toxic. Keep
containers sealed and away from
children. If coolant is accidentally
consumed seek medical help
straight away.
WARNING: If the engine is stopped
due to the Eco Start-Stop System be
aware that the engine may restart
without warning.
WARNING: The engine must be
switched off before carrying out the
coolant level check and top up
process.
NOTE: The coolant filler valve is
located in the tonneau
compartment behind the right-hand
seat.
ENVIRONMENTAL: When topping up
take care not to spill any coolant.
Coolant must not be allowed to escape
into the soil or waterways.
1. Open the tonneau cover. See Tonneau
Cover, page 1.9.
2. Slowly unscrew the cap by half a turn
anti-clockwise and allow excess
pressure to escape.
3. Unscrew the cap fully and remove it.
4. Check the level of coolant. The coolant
level is correct when it is at the top of
the + marker.
5. Top up the coolant if necessary. See
Coolant, page 7.10.
6. Replace the cap by turning it clockwise
to the stop.
NOTE: Ensure the cap is refitted
securely.
