lation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly .•
App lies to veh icles: with Tire pressure monitoring syste m
Introduction
The tire pressure monitoring system monitors air pres­
sure in all four road wheels and the spare tire* while the
vehicle is moving.
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or several tires, text messages and yellow
symbols appear in the instrument cluster display to alert the driver.
The
1warning light in the instrument cluster comes on when the tire
is significantly underinflated
=> page 17.
The warning light
L also illuminates in the case of a system malfunc­
tion.
The system continuously receives radio signals from sensors located
inside each tire.
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
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when the tires 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 cali­
brated, tire pressure on all four tires and on the spare tire* should be
checked at regular intervals, adjusted if necessary and saved in the
proper setting (recommended pressure)=>
page 330.
The tire pressure is shown on the tire pressure label. On USA vehicles,
the tire pressure label is located on the driver's side B-pillar. On
Canada vehicles, the tire pressure label is located either on the
Safety first
driver's side B-pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle 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 310.
The current temperatures and pressure of your tires can be viewed in
the MMI
=> page 329.
& WARNING
• 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 possible, and inflate
them to the proper pressure as indicated on the vehicle's tire pres­ sure label =>
page 310. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure. Under­
inflation also is likely to impair the vehicle's handling and stop­
ping ability.
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
<£> For the sake of the environment
Driving with under-inflated tires reduces fuel efficiency and tire tread
life.
(I) Tips
• Each tire, including the spare*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 310.
• The tire pressure monitoring system helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure. .,,,

Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.
In order for the tire pressure monitoring system to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressure, for example when the load
condition of your vehicle changes . Proceed as follows:
Corr ecting tir e pr essure
- Check the pressure in the tires (including the spare t ire*) .
- Adjust air pressure as needed in accordance with t he infor -
mation on the label located e ither on the driver's side B ­
pillar (visible when the door is open), inside the fuel filler
flap and additionally in the manual.
Saving tire p ressures
- Turn on the ignition.
- Press the [
CAR] function button .
- Select
Systems in the CAR menu .
- Select
Tire pressure mon itoring .
-Select Sto re curr. tire pressure s~ page 329, fig . 259 .
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be resaved . After the
pressures are saved, the tire pressure monitoring system
measures the c urrent tire pressures and saves them as the new spec­
ified pressures .
(I] Tips
• The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B-pillar. On
Canada veh icles, the tire pressure label is located either on the
driver's side B-pillar or inside the fuel filler flap . The tire pressure
label lists the recommended cold t ire inflation pressures for the
vehicle 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 310.
• The tire pressure monitoring system helps the driver to keep an
eye on tire p ressures. But the driver still has the responsib ility for
maintaining the correct tire pressure .
• If your veh icle is eq uipped w ith a standard spare ti re*, it must be
inflated to the maximum pressure specified for the vehicle .•

Changing a wheel
When you change a wheel, the new tire must be initial ­
ized.
Turn on the ignit ion .
- Press the

What do I do now? -____________________ .:..::......:..:...___Wi'.'11
- Disengage and lower the floor panel before you close the
luggage compartment lid again.
Storing the replaced wheel
-Place the replaced wheel inside the spare wheel well in the
luggage compartment.
Tighten the knurled retaining screw clockwise to secure
the wheel in place.
- Disengage and lower the floor panel before you close the luggage compartment lid again.
& WARNING
Loose items in the passenger compartment can cause serious
personal injury during hard braking or in an accident.
• Never store the spare wheel or jack and tools in the passenger
compartment.
• Always store all jacking equipment, tools, and the spare wheel
in the luggage compartment.
• Tighten the knurled retaining screw for the spare wheel
securely.
[I] Tips
Check the inflation pressure of the spare tire periodically to keep the
tire ready for use .•
Safety first
Changing a wheel
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
- After you experience a tire failure, pull the car well away
from moving traffic and try to reach
level ground before
you stop ~& .
- All passengers should
leave the car and move to a safe
location (for instance, behind the guardrail)~& .
- Engage the
parking brake to prevent your vehicle from
rolling unintentionally~ &.
- Move
selector lever to position P ~ & .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Take the
jack and the spare tire out of the luggage
compartment~
page 333 .
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn
off the engine, turn the emergency flashers on and use other
warning devices to alert other motorists.
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed. When
one front wheel is lifted off the ground, placing the Automatic ..,
