warning system
Driver inform ation system
The speed warning system warns the driver if he exceeds a previ ­
ously stored maximum speed. A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 6 miles per hour (10 km/h). At the same time, a warning symbol appears in the
display=> fig. 23.
The speed warning system has
two warning thresholds that func ­
tion independently of each other and that have somewhat different
purposes :
Speed warning 1 )f ..._ (Canada models)
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
J I ,.... (Canada models) in the warning 1
display appears when you exceed the maximum speed . It goes out
when the speed falls below the stored maximum speed.
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is deleted .

Speed warning 2 ...,,, /
e!. (Canada models)
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbol, / ) (Canada models) appears in the
display when you exceed the stored speed limit. Unlike warning 1,

Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significant ly
under -inflated. The TPMS only provides a low tire pressure warning
and does not reinflate your tires.
Accordingly, when the low tire pressure tellta le illuminates, you
should stop and check your tires as soon as possib le, and inflate
them to the proper pressure. Driving on a significantly under­
inflated t ire causes the tire to overheat and can lead to tire failure .
Under -inflation a lso reduces fuel efficiency and tire tread l ife, and
may affect the vehicle's handling and stopping ability.
(D Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's respons ib ility to maintain correct
tire pressure, even if under -inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale .
• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflat ion pressure recommended by the
vehic le manufacturer on the vehicle p lacard or tire inflation pres ­
s u re label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure labe l, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure _.,
