Setting values to zero
-Press the I CAR I function button.
- Select
Instrument cluster.
-Select Trip computer 1 or Trip computer 2.
-Select Reset to delete all the values in the memory

Displaying and hiding driver information
-Press the I CAR I function button.
- Select
Instrument cluster.
- Selec t Trip computer 1 or Trip computer 2.
-Select, for example, Fuel range On to turn on the display
or
Off to turn the display off.
All values in the single-trip or the total-trip memory can be reset to
zero simu ltaneously in the MMI. In addition you can determine what
driving information from the trip computer shou ld be shown in the
instrument cluster display . If one of the pieces of driver information
is turned
off, that driver in formation will not be shown in the display.
The information will continue to be calculated by the trip computer
and can be turned back
on at any time. •
Tire pressure monitoring system
General notes l )
Each tire, including the spare (if provided), should be checked
monthly when co ld and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres­
sure label, you should determine the proper tire inflation pressure
for those tires.)
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 significantly
under-inf lated . Accordingly, when the low tire pressure telltale illu­
minates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly
under -inflated 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 vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver's responsibility to maintain correct tire .,_

pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure tellta le .
Your vehicle has also been equipped with a TPMS malfunction indi­ cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low t ire pressure
telltale . When the system detects a ma lfunction, the telltale wil l
fl ash for approximately one minu te and then remain continuously
illuminated . T his sequence will continue upon subsequent vehicle
start-ups as long as the ma lfunction exists.
When the malfunction indicator is illuminated, the system may not be ab le 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
veh icle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels allow the TPMS to continue to function
properly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the tire pressure mon itoring system senses a s ignificant
loss of air pressure in one or severa l tires, text messages and yellow
symbo ls appear in the instrument cluster display to a lert the driver .
T he ~ warning light in the instrument cluster comes on when the
t ire is significant ly underinflated ;;:,
page 20.
The warning light ' also illuminates in the case of a system
malfunction.
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °Cl 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 only when they are cold, when the temperature of the tires
is roughly the same as the ambien t air temperature .
In order to keep the tire pressure monitoring system properly cali ­
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 45.
The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure labe l is located on the driver's side 8-pi llar . On
Canada vehicles, the tire pressure labe l is located eithe r on the
driver's side 8 -p illar or inside the fuel fi ller flap. The tire pressure
label lists the recommended cold tire inflation p ressu res for the
vehic le at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire
pressures for normal load conditions, please see chapter
;;:, page 351.
& WARNING
• When the tire pre ssure monitoring sy stem warning light i s lit ,
one o r mor e of your tires i s signifi ca ntl y under -infl ated . You should
stop and che ck your tire s as soon as possible , and inflate th em to
th e prop er pre ssure a s indicated on the v ehicle' s tir e pr ess ure
l a bel ;;:,
pa ge 351. Driving on a signifi cant ly under-infl ated tire
ca use s the tire to overhe at and can lead t o tire f ailure. Und er-infla ­
tio n a lso is likely to imp air th e vehicle' s handling and stoppi ng
ability .
• Do not adju st tire pre ssure whe n tire temp erature is exc essiv e.
Thi s could le ad to serious tire damage and even cause the ti re to
burst , with the additi onal d ange r of an acc ident .
Driving with under -inflated tires reduces fue l efficiency and tire
tread life.
