Tire pressure display screen
Meaning
(3) Benchmark pressure, front tires
(4) Current tire pressure, front right tire.
(5) No data received, right rear tire.
(6) Benchmark pressure, rear tires

If the tire pressure is too low, the relevant tires and the respective readings are highlighted in yellow.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the
inflation pressure recommended 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 pressure 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
underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check
your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly
underinflated 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 maintenance, 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 telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system
is not operating properly. 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 start-ups
as long as the malfunction exists.
When the malfunction 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. 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.
Spare wheel or compact spare wheel
The spare wheel or compact spare wheel has no tire pressure sensor. When the spare or compact
spare wheel is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS) indicator light will
flash in the instrument cluster display. The TPMS continues to monitor the other 3 wheels.
Tire storage
If the tires do not move for an extended period of time, the sensors will not transmit tire pressures to
the system. This saves sensor battery life. When the ignition is switched on, the sensors transmit
signals to the Tire Pressure Monitoring System.

The Tire Pressure Monitoring System may not react at first or may not react at all when you are driving
in a sporty manner, or on snow-covered or unpaved roads, when you are driving with snow chains, or
in certain other situations. A change in the tread circumference of a tire is signaled by the Tire
Pressure Monitoring System indicator in the instrument cluster (telltale).
The tire pressure recommended for the tires originally installed on the vehicle is on a sticker on the
driver door jamb
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the
inflation pressure recommended 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 pressure label, you should determine the proper tire inflation pressure for those
tires.)

your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
Resetting and recalibrating the benchmark tire pressure
Resetting the tire pressures in the Multi-function Display (MFI) resets the benchmark tire pressure
used by the TPMS to the current tire pressure in the tires based on the circumference of the tires.
To reset the reference tire pressure, switch on the ignition. In the MFI, navigate to the Settings
menu and select Tire pressure. Store and confirm the new tire pressures.
The recalibration must be performed each time the tire pressure in one or more tires has been
adjusted or after one or more tires has been changed, exchanged, or repaired. The new tire pressures
are stored in the system only after at least 20 minutes of normal driving.
If you have reset the benchmark tire pressure when your tires do not have the correct tire pressure,
this will prevent the TPMS from working properly. It may then give false warnings or may not give any
warning even if the tire pressure is too low.
For this reason, it is vital to make certain that all 4 tires are inflated to the correct pressure
when they are cold, before calibrating the system. Cold tire tires are tires that have not been driven
more than a couple of miles (kilometers) at low speed within the last 3 hours.
Recalibrate the system to reset the benchmark TPMS pressure in the following
situations:
x After installing tires on your vehicle that have recommended cold tire inflation pressures that are
different from the tires that were taken off.
x After any tire on your vehicle is removed and then remounted, even if the same tire and wheel rim
that were taken off are reinstalled (for instance, after repair).

x If necessary, return the vehicle tool kit to its location in the luggage compartment.
x Unhook the floor covering and fold it back down onto the floor of the luggage compartment.
x Close the luggage compartment lid.
If the spare wheel is different from the road wheels
If the spare is different from the road wheels, a compact spare wheel, for example, or if the road
wheels are winter tires, the spare wheel must be used only in the event of a flat tire, only for a brief
time, and only when driving with extra caution ⇒ .
Replace it with a tire matching the others on your vehicle as soon as possible.
Please heed the following:
x Do not drive faster than 50 mph (80 km/h)!
x Avoid full-throttle acceleration, hard braking and fast cornering!
x Do not use snow chains on the compact spare wheel
x After installing the spare wheel or compact spare wheel, check the tire pressure as soon as
possible
Check the tire inflation pressure of the spare or compact spare whenever you check the tire pressure
of the road wheels, at least once a month. Inflate a spare wheel to the cold tire pressure specified for
the vehicle's road wheels on the tire pressure label; inflate a compact spare wheel to the cold tire
pressure specified for the compact spare on the tire pressure label or on a separate label for the
compact spare, if there is one.
WARNING
Improper use of a spare wheel or a compact spare wheel can cause loss of vehicle control, a
crash or other accident, and serious personal injury.
x Never use a spare wheel or compact spare wheel if it is damaged or worn down to the
wear indicators.
x In some vehicles, the spare wheel or compact spare wheel is smaller than the original tire.
A smaller compact spare wheel is identified with a sticker and the words “50 mph” or
“80 km/h”. This is the maximum permissible speed when driving with this tire.
x Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle
acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front
axle (drive axle).
x Replace the compact spare with a normal wheel and tire as soon as possible. Compact
spare tires are designed for brief use only.
x Regularly check the U.S. DOT Tire Identification Number (TIN) to determine the age of the
compact spare wheel Tires age even if they are not being used and can fail suddenly,
especially at higher speeds.
x Tires that are more than 6 years old can only be used in an emergency and then with
special care and at lower speeds.
x The compact spare wheel must always be secured with the wheel bolts provided by the
factory.
x Never drive using more than one compact spare wheel.
x After installing the compact spare wheel, the tire pressure must be checked as soon as
possible
x Snow chains cannot be used on the compact spare wheel. If you must use snow chains
and have a compact spare wheel mounted, move the compact spare wheel to the rear axle if a
front tire has to be replaced. The tire taken off the rear axle can then be used to replace the
flat front tire. Be sure you do not change the tire's direction of rotation. Install the snow
chains on the full-sized road tire.

WARNING
Using incorrect or unmatched tires and/or wheels or improper tire and wheel combinations
can lead to loss of control, collision and serious personal injury.
x Always use tires, wheels and wheel bolts that meet the specifications of the original
factory-installed tires or other combinations that have been specifically approved by the
vehicle manufacturer.
x All 4 wheels must be fitted with radial tires of the same type, the same size (tread
circumference), and the same tread pattern. Driving with different tires reduces vehicle
handling and can lead to a loss of control.
x Never drive faster than the maximum speed for which the tires installed on your vehicle
are rated because tires that are driven faster than their rated speed can fail suddenly.
x Overloading tires can cause heat build-up, sudden tire failure, including a blowout and
sudden deflation and loss of control.
x Temperature grades apply to tires that are properly inflated and not over- or underinflated.
