lowered according to the selected level
setting and to the vehicle speed:

With increasing speed, ride height is re-
duced by up to approximately 0.8 in
(20 mm).

With decreasing speed, the ride height
is again raised to the selected vehicle
level.The following vehicle level settings can be
selected when the vehicle is stationary:

7Yellow and red guide lines for cornering
When you turn the steering wheel out of
the straight-ahead position, the positions
of the yellow and red guide lines7
change depending on the steering wheel’s
position. The space required by the vehicle
for reverse cornering is indicated by yellow
and red guide lines7.
Warning!G
Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance as the use of the guide lines to judge
distance increases the risk of impacting the
objects.
Even when the object you approach is di-
rectly on the ground (and nothing on the ob-
ject extends above the ground beyond the
object’s contours directly touching the
ground) and no objects that do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck are in the path, do not ap-
proach the object on the ground any closer
than red guide line4.

Image on multifunction display
When you switch on Night View Assist, the
image for the speed gauge changes on the
multifunction display. The speed gauge is
shown as a bar on the lower edge of the
multifunction display. The line for main
menus is no longer available. If you would
like to change a setting using the steering
wheel buttons, you must first switch off
Night View Assist.
iInfrared light is invisible to the human eye
and can therefore remain permanently switched
on without blinding oncoming traffic.
iThe infrared headlamps only come on above
a speed of approximately 9 mph (15 km/h).
Therefore, when you are at a standstill, you do
not have a complete view and cannot check the
function of the Night View Assist.

560 Operation
Tires and wheels
Tire inflation pressure changes by approxi-
mately 1.5 psi (0.1 bar) per 18°F (10°C) of
air temperature change. Keep this in mind
when checking tire inflation pressure
where the temperature is different from
the outside temperature.
Checking tire inflation pressure
Regularly check the tire inflation pressure
at least once a month.
Check and adjust the tire inflation
pressure when the tires are cold. The tires
can be considered cold if the vehicle has
been parked for at least 3 hours or driven
less than 1 mile (1.6 km).
If you check the tire inflation pressure
when the tires are warm (the vehicle has
been driven for several miles or sitting less
than 3 hours), the reading will be
approximately 4 psi (0.3 bar) higher than
the cold reading. This is normal. Do not let
air out to match the specified cold tire in-
flation pressure. Otherwise, the tire will be
underinflated.Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
Remove the cap from the valve on one
tire.
Firmly press a tire gauge onto the
valve.
Read tire inflation pressure on tire
gauge and check against the recom-
mended tire inflation pressure on the
Tire and Loading Information placard
on the driver’s door B-pillar
(
page 553) or, if available, the tire in-
flation pressure label on the inside of
the fuel filler flap. If necessary, add air
to achieve the recommended tire infla-
tion pressure.
Warning!G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit or total load limit as indi-
cated on the Tire and Loading Information
placard located on the driver’s door B-pillar.
Overloading the tires can overheat them,
possibly causing a blowout. Overloading the
tires can also result in handling or steering
problems, or brake failure.

iReactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire inflation pressure should only be adjusted
on cold tires. Observe the recommended tire in-
flation pressure on the Tire and Loading Informa-
tion placard on the driver’s door B-pillar
(
page 553). Some vehicles may have supple-
mental tire inflation pressure information for
driving at high speeds (
page 559) or for vehi-
cle loads less than the maximum loaded vehicle
condition. If such information is provided, it can
be found on the inside of the fuel filler flap
(
page 538).
iAfter wheel rotation or sensor replacement,
the vehicle must be parked for 20 minutes be-
fore attempting to reactivate the TPMS.
iThe menu overview can be found on
(
page 266).iWhen the wheel positions are changed on
the vehicle, it is possible that the air pressure is
temporarily displayed for the wrong position.
This will be corrected after driving for several
minutes, and the air pressure will be shown for
the correct position.


565 Operation
Tires and wheels
Run Flat Indicator (Canada only)
While the vehicle is being driven, the Run
Flat Indicator monitors the set tire inflation
pressures by evaluating each wheel’s rota-
tional speed. This allows the system to de-
tect a significant loss of pressure in a tire.
If a wheel’s rotational speed changes due
to falling tire inflation pressure, you will
see a corresponding warning message in
the multifunction display.
The Run Flat Indicator may function in a re-
stricted manner or with a delay if:

snow chains are mounted to the
vehicle

in presence of ice and snow

you are driving on a loose surface (e.g.
sand or gravel)

you are driving in a very sporty manner
(involving rapid acceleration or high
speeds in curves)
Warning!G
When the multifunction display shows the
message “Tire pressure Check tires”, one or
more of your tires is significantly under-in-
flated. You should stop and check your tires
as soon as possible, and inflate them to the
proper tire inflation pressure as indicated on
the vehicle’s tire information placard. Driv-
ing on a significantly underinflated tire caus-
es the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability. Each
tire, including the spare, should be checked
monthly when cold and set to the tire infla-
tion pressure recommended by the vehicle
manufacturer on the vehicle placard or the
tire inflation pressure label.
Warning!G
The Run Flat Indicator does not provide a
warning for wrongly selected tire inflation
pressures. Always adjust tire inflation pres-
sure according to the placard on the driver’s
door B-pillar or fuel filler flap.
The Run Flat Indicator does not replace reg-
ular checks of the tire inflation pressures
since a gradual pressure loss in more than
one tire cannot be detected by the Run Flat
Indicator.
The Run Flat Indicator is not able to issue a
warning due to a sudden dramatic loss of
tire inflation pressure (e.g. tire blowout
caused by a foreign object). In this case
bring the vehicle to a halt by carefully apply-
ing the brakes and avoiding abrupt steering
maneuvers.
