To ta l-tr ip mem ory ( Trip compu te r 2)
Unlike the single -trip memory, the total -tr ip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manua l resets.
Fu el r an ge
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to travel on the
current tank of fuel and with the same driving sty le . The display
changes in increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
t he last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Average fuel m ile ag e
The average fuel economy in MPG (1/100 km) since you last cleared
the memory appears in this display. You can use this display to
adjust your driving technique to achieve a desired mileage.
C ur rent fuel mil eage
The instantaneous fuel consumption in mi les per gallon (1/100 km)
is shown in th is d isplay. You can use this display to adjust your
driving technique to achieve a desired mileage.
Fue l consumption is recalcu la ted at intervals of 33 yards (30
meters). When the vehicle is stationary, the most recent fuel
consumption is d isplayed .
Average speed
The average speed in mph (km/h) s ince the last time the display was
reset appears in the display .
Elap se d time
The length of time that you have been driving since you last reset
the memory appears in this display.
Di stance
The elapsed distance since the last time the memory was cleared
appears in the display. The maximum distance that can be recorded
is 9,999 .9 miles (9,999 .9 kilometers).

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 _.,

telltale. When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle
starts up as long as the malfunction exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels al low the TPMS to continue to function
proper ly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the t ire pressure monitoring system senses a s ignificant
loss of air pressure in one or several tires, text messages and yel low
symbo ls appear in the instrument cluster display to a lert the driver.
The warning light in the instrument c luster comes on when the
tire is significantly underinflated
=> page 17.
The warning light
malfunction . also
illuminates in the case of a system
Be aware that tire pressure is also dependent on the temperature of
the tire . For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1 .5 psi (0. 1 bar) . The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure on ly when they are
cold , when the temperature of the tires
is roughly the same as the ambient air temperature.
In order to keep the tire pressure monitoring system properly ca li­
brated, tire pressure on all four tires should be checked at regular intervals, adjusted if necessary and saved in the proper setting
(recommended
pressure)=>
page 44.
The tire pressure is shown on the label located on the driver 's side
B -pillar (visible when the door is open) .
& WARNING
• When the tire pre ssure monitor ing system warn ing light i s lit ,
one or more of your t ir es is s ignificantl y unde r-inflated . You should
s top and check your tire s as s oon as po ssible , and inflate them to
the p rope r pre ss ure as indi cated on th e vehicl e's tire pr essure
label
=> pag e 242. Driv ing on a s ignific antl y un der-inflated t ire
c a use s the tire to overhe at and can le ad to tire fa ilure. Unde r-inf la­
ti on also i s lik el y to impair the vehicle' s handling and stopping
ability .
• Do not adju st t ir e pressur e wh en t ire t emp erature is exce ssiv e.
Thi s could le ad to seriou s tire dam age and even cau se the tire t o
bur st, w ith the addition al dan ger of an accident.
W For the sake of the environment
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire should be checked month ly when the temperature of
the tires is abou t the same as ambient air temperature and s et to the
recommended inflation pressure as specified on the tire pressure
label =>
page 242.
• The factory supplied spare whee l is equipped with a se nsor for
the tire pressure monitoring sys tem. As long as the spare wheel is
n ot mounted, the tire pressure of this tire wil l not be monitored.
• T he tire pressure monitoring system he lps the driver to keep an
eye on tire pressures . But the driver still has the responsibility f or
maintaining the correct tire pressure . .,_

Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.
F ig . 29 S ET -butt on:
T ire pressure mon i­
t or ing syste m
In order for the tire pressure monitori ng system to operate
appropr iately, you have to re-save the specified p ressures
whenever you adjust tire pressures, for example when the load co nd ition of your vehicle changes. Proceed as fo llows:
Corr ecting tir e pr es sure
Check the pressure in the t ires.
- Adjust air pressure as needed to comply w ith the infor­
mat ion on the label located on the driver's side B -pillar
(visible when the door is open) .
Saving tire pressures
-Turn on the igniti on.
- Press the button :::> fig. 29 for app rox imately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three t imes .
All pressure warning indicators in the d isplay will be canceled. Following each intentional change in specified pressures, ti
re pres ­
sures must be resaved.
After the pressures are saved, the tire pressure monito ring system
measures the current tire pressures and saves them as the new
spec ified pressures .
[ i ] Tip s
• The tire pressure is shown on the tire pressure labe l. The tire
pressur e lab el is located on the driv er's sid e B-pillar (visible when
the door is open). The tire pressure label l ists the recommended
cold tir e inflation pr essur es for the vehic le at its maximum capacity
weigh t and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for norma l load
conditions, please see chapter~
page 242.
• The tire pressure monitoring syst em he lps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the cor rect tire pressure .•
Wheel change
If a wh eel is ch anged , the wheels tha t were exchan ged
have to be re -programmed.
- Tu rn on the ignition.
- Press the button :::> fig. 29 for approximately 5 seconds .
You will hear a beep and the symbol in the button flashes
three times.
Programming is necessary :
• after the t ires have been rotated on the vehicle, or the spare tire
is used,
• if tires with new wheel sensors are used .
All pressure warning indicators in the disp lay wil l be canceled . The
system malfunction error message will not disapp ear until the .,_
