Coolant
The engine coolant is a mixture of water and
anticorrosion/antifreeze.
To check the coolant level the vehicle must be
parked on level ground and the engine must
have cooled down. For more information, see
"Coolants" (
page 309).Checking coolant level
The coolant reservoir is located in the front
compartment on the driver’s side.

Warning!
In order to avoid potentially serious
burns:
• Use extreme caution when opening the
service flap if there are any signs of
steam or coolant leaking from the
cooling system, or if the coolant
temperature warning lampD in the
instrument cluster indicates that the
coolant is overheated.
• Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid
and is under pressure.
• Using a rag, slowly open the cap ap
proximately
1/2 turn to relieve excess
pressure. If opened immediately,
scalding hot fluid and steam will be
blown out under pressure.

Coolant temperature warning lamp
Illuminates:
• when the ignition is switched on.
The warning lamp goes out if the engine is
running.
• if the coolant is too hot.
>Stop the vehicle immediately in a safe
location.
>Do not continue to drive.
>Turn off the engine.
>Set the parking brake when leaving the
vehicle.
>Contact Roadside Assistance or an autho
rized smart center.If the coolant level has fallen below the
marking bar on the coolant reservoir
(
page 178):
>Add coolant as required.
>Have the coolant system checked for leaks
at an authorized smart center.

Among other possible causes, the
polyVbelt could be broken. Do not continue
to drive. Otherwise, the engine will overheat
due to an inoperative water pump which may
result in damage to the engine.
When the system detects a malfunction,
the telltale will flash for approximately
1 minute and then remain continuously
illuminated.
This sequence will continue upon subse
quent vehicle startups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a vari
ety of reasons, including the installation
of incompatible replacement or alternate
tires or wheels on the vehicle that pre
vent the TPMS from functioning properly.
Always check the TPMS malfunction tell
tale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
G
Warning!
Driving when your engine is overheated
can cause some fluids, which may have
leaked into the engine compartment, to
catch fire. You could be seriously burned.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until
the engine has cooled down.
