failure. Under-inflation also reduces fue l efficiency and tire tread
life, and may affect the veh ic le's handling and stopping abi lity.
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under-inflation has not reached the leve l to tr igger
illumination of the TPMS low tire pressure tellta le.
Your veh icle has a lso been equipped with a TPMS malfu nction indi­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined w ith the low tire press ure
telltale . When the system detects a ma lfunction , the telltale wi ll
fl ash for approximately one minute and then remain continuously
illum inated . This sequence will continue upon subsequent vehicle
start -ups as long as the ma lfunction exists.
When the ma lfunctio n indicator is i llum inated, the system may not
be ab le to detect or signa l low tire pressure as intended . TPMS
malfunctions may occ ur for a var iety of reasons, i nclud ing the
installation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from f unctioning proper ly . Always
check the TPMS malfunction tellta le after replac ing one or more
t ires or whee ls on yo ur ve hicle to ens ure t hat the replacement or
a lternate tires and wheels allow the T PMS to continue to function
proper ly. •
Introduction
The tire pressure monit oring system m onitors air pressure
in all four road wheels and the spare tire* while the
vehicle is movin g.
As soon as the tire pressure moni toring system se nses a signi ficant
loss of air pressure in one or severa l tires, text messages and yellow
symbo ls appear in the inst rume nt cluster d isplay to aler t t he driver .
T he
(l) warning light in the instrument c luster comes on when the
t ire is sig nificant ly underinflated
=> page 20 .
Controls and equip­
ment
Driver information di splay
The warning light U) also i lluminates in the case of a system
mal fu ncti on.
The system continuous ly receives rad io signa ls from sensors
located inside each tire .
Be aware that t ire p ressu re is also dependen t on the tempera ture of
the tire . For every
18 °F (1 O °C) increase in tire temperature, tire pres­
sure increases by about 1 .5 psi (0 .1 bar). The tire warms up wh ile the
vehicle is moving and t ire pressure rises . So you should adjust tire
pressure only when the t ires are
cold, when the temperature of the
tires is roughly the same as the ambient air temperature .
I n order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on all four tires and on the spare tire* should
be checked at regular intervals, adjusted if n ecessary and saved in
the proper setti ng (recommended
pressure) => page 44.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure labe l is located on the drive r's s ide B -p ill ar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -pillar o r inside the fuel fi ller flap. The t ire press ure
label l ists t he recommended cold tire inflat io n pressures for t he
vehic le at its maximum capacity weight and the tires that were on
your ve hicle at the time it was manufactured . For recommended tire
pressures for normal load condit ions, please see chapter
=> page 328 .
The current temperatures and pressure of your tires can be viewed
in the M MI
=> page 43 .
& WARNING
• When the tire pre ssure monitoring system warning light i s lit ,
one or more of your tires is signifi cantly under -infl ated . You should
stop and check your tires a s soon a s po ssible , and inflate them to
the proper pre ssure a s indi cated on the vehi cle' s tire pre ssure
label
=> page 328 . Driving on a significantly under -inflated tire

• Green: If current tire pressure and the spec ified pressure are
approximate ly the same, t he tire pressure is shown in green.
• Yellow : If current tire pressure is too low with respect to specified
pressure, the tire pressure is shown in yellow.
[ i ] Tips
• During the learn ing period, t ire pressure and t ire temperature
are not displayed . Horizontal lines--,-- are displayed for pressure
and temperature.
• The tire pressure is shown on the label located either on the
driver's side B-pi llar (visible when the door is open) or ins ide the fuel
filler flap .
• The tire pressure monitor ing system he lps the driver to keep an
eye on tire pressures . But the driver stil l has the responsibility for
maintaining the correct t ire pressu re .•
Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reli able tire pressure moni toring .
In order for the tire pressure monitor ing system to o perate
appropr iately, you have to re-save the specified p ressures
whenever you adjust tire pressure, for example when the load condition of your vehicle changes . Proceed as fo llows :
Correcting tire pressure
-Check t he pressure in the tires ( includin g the spare tire*).
-Ad just air pressure as needed in accordance with the
informat io n on the label loca ted either on the d river 's
side B- pillar (visible whe n the do or is ope n), ins ide the
f u el fill er flap a nd a ddit ionally in the manua l.
Saving tire pressur es
-Tur n on the ignition .
-Press the I CAR] fu nct ion button .
-Select Systems in the CAR me nu.
-Selec t Tire pressure monitoring .
-Select Store curr. tire pressures=> page 43, fig. 27.
A ll pressure warning indicators in the display wi ll be cance led .
Following each intentional cha nge in speci fied pressures, tire pres ­
sures must be resaved.
Afte r the pressures are saved, the tire pressure monitoring system
measures the current t ire pressures and saves them as the new
specified pressures .
[ i] Tip s
• T he tire pressure is shown on the tire pressure label. On USA
veh ic les, the tire pressure label is loca ted on the driver's side B­
pillar . On Canada vehicles, the tire pressure labe l is located either on
t he dr iver's side B -p illar or i nside the fuel filler flap . The t ire pressure
label lists the recommended cold tire inflation pressures for the
vehic le at its maximum capacity weight and the tires tha t were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
=> page 328.
• The tire pressure monitoring system he lps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
• If your vehic le is equipped with a standard spare tire *, it must be
inflated to the maximum pressure spec ified for the vehicle. •

In a collision , the laws of physics mean that even smaller items that
are loose in the vehicle will turn into heavy missiles that can cause
serious injury. Items in the vehicle pick up kinetic energy which
varies with the vehic le and the weight of the item . Vehicle speed is
the most significant factor.
For example , in a frontal collision at a speed of 30 mph (48 km /h) ,
the forces acting on a 10-lb (4 .5 kg) object are about
20 times the
normal weight of the i tem . This means that the weight of the item
would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an i tem of tha t weight flying free ly _,,,

If necessary, retighten the mountings and check the entire system
from time to time.
• After mounting a roof rack system, or when you transport
objects on the roof of your vehicle, the height of the vehicle is natu­
ra lly increased . Be careful when driving under low bridges or in
parking garages for examp le. This cou ld cause damage to the load
and even the vehicle itself. •
Mounting locations
Safe installation of a roof rack requires that the rack
sup ports are m ounted between the small arrows marked
inside the door frames on all four doors .

Mount the roof racks suppo rts in the side roof moldings. Make sure
to position the supports on
all four doors between the points
marked by small
arrows => fig. 109. The markings can only be seen
when the doors are open . •
Loading the roof rack
Always distribute loads evenly. Make sure anything on the
r o of rack is securely tied down .
-Always distribute the loads on the roof rack evenly.
Always attach items to the roof rack securely before you
drive off.
T he maximum permissible roof weight is 220 lb (100 kg ). The roof
we ight is made up o f the weight of the roo f rack system and the
weight of the object being transported .
When using a roof rack system which has a lower load carrying
capacity, you must not use up the total maximum permissible load
carrying capacity specified above . Instead, you should load the roof
r ack system only to the maximum capacity specified by the manu ­
facturer of the roof rack system .

Starting off with a trailer To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and prevents the vehicle
from rolling backward.
- You can release the switch once you are sure that you are
developing enough forward momentum at the wheels as
you depress the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch
pulled out and accelerating -just as you would when starting on a
hill with a conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- Pull the switch and continue to pull it to slow your vehicle
with the parking brake in an emergency.
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . The vehicle is
braked at all four wheels by activating the hydraulic brake system.
Brake performance is similar to making an emergency
stop~ &.
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as the switch is released
, or the accelerator pedal is depressed, emer­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The laws
of physics cannot be suspended even with ESP and its associated
components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away -risking an
accident. •
Driver messages in the instrument cluster
Caution: Vehicle parked too steep
This message appears when the parking brake is applied on an
incline that exceeds about 30%.
In this case the braking power of the parking brake may
not be
adequate
to prevent the vehicle from rolling unintentionally.
Please release parking brake
This message appears, when a gear is selected and the accel erator
pedal is depressed -release the parking brake.
Press brake pedal to release parking brake
This driver message appears when the switch to release the parking
brake was pressed. The parking brake can only be released if you
press the brake or accelerator pedal and press the switch at the
same time .
~ Parking brake malfunction !
This driver message appears together with the yellow 'Jlf symbol
when there is a parking brake malfunction.
