G
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

H
The yellow warning lamp for the
tire pressure monitoring system
comes on.
The tire pressure monitoring system de-
tects a loss of pressure in at least one tire.

Bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
Observe the traffic situation around you.

Take note of the messages in the multi-
function display.
The warning lamp goes out once the tire in-
flation pressure monitor has been reactivat-
ed after the tire inflation pressure has been
corrected.
Warning!
G
When the tire pressure monitoring system
warning light is lit, one or more of your tires
is significantly under-inflated. You should
stop and check your tires as soon as possi-
ble, and inflate them to the proper pressure
as indicated on the vehicle’s tire information
placard. Driving on a significantly under-in-
flated tire causes the tire to overheat and
can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended inflation pressure as specified in
the vehicle placard and owner’s manual.
iThe recommended tire inflation pres-
sures for your vehicle can be found on
the tire placard on the driver’s door
B-pillar, not in the owner’s manual.
