Parktronic is an electronic parking aid
and informs you visually and audibly of
the distance between the vehicle and an
obstacle.
Parktronic is automatically switched on
when you switch on the ignition and re-
lease the handbrake. You must also
move the selector lever to position
D, N
or R.
Parktronic switches off at speeds of over
11 mph (18 km/h). It switches on again
as soon as the vehicle’s speed falls be-
low this limit speed.
Parktronic is equipped with sensors in
the front and rear bumper to monitor the
area around your vehicle.
Range of the sensorsThe sensors must be free from dirt, ice
and slush, otherwise they may not func-
tion correctly. Clean the sensors regu-
larly, taking care not to scratch or
damage them (

If an obstacle is within this range, all seg-

and a warning tone sounds (the warning
for the front sounds different than the
warning for the rear). The distance may
no longer be displayed if you drive the
vehicle closer to the obstacle than the
minimum distance.

You will find information about the
speed limit for your tires under “Tires
and wheels” in this section
(\2
page 383).
Check regularly, e.g. weekly or when re-
fueling:
\4
the vehicle lighting
\4
the condition of the tires
(\2
page 346) and the tire pressures
(
\2
page 361)
\4
the engine oil level (
\2
page 322)
\4
the brake fluid level (
\2
page 331)
\4
the fluid level in the windshield wash-
er system / headlamp cleaning sys-
tem reservoir (

\4
the contamination level of the rear

Your vehicle is equipped with monolith-
ic-type catalytic converters, an impor-
tant element in conjunction with the
oxygen sensors to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined in your Service Booklet.
Warning
G
Exceeding the permissible maximum
speed can cause tire damage, which
could lead to loss of control of the vehi-
cle.
As the driver, you must find out about the
maximum speed of the vehicle and the re-
sulting permissible maximum speed of
the tires (tire and tire pressure).
Never exceed the speed limit for your
tires under any circumstances
(\2page 383).

Driving tips

Your vehicle is equipped with an oxida-
tion catalyst, an important element in
conjunction with the oxygen sensors to
achieve substantial control of the pollut-
ants in the exhaust emissions. Keep
your vehicle in proper operating condi-
tion by following our recommended
maintenance instructions as outlined in
your Service Booklet.
!
CAUTION
To prevent damage to the catalytic
converters, only use premium un-
leaded gasoline in this vehicle.
Any noticeable irregularities in en-
gine operation should be repaired
promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter,
causing it to overheat and potentially
start a fire.
Warning
G
As with any vehicle, do not idle, park or
operate this vehicle in areas where com-
bustible materials such as grass, hay, or
leaves can come into contact with the hot
exhaust system, as these materials could
be ignited and cause a vehicle fire.

368 OperationTires and wheels

The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation
pressure, as selected by the driver, in all
four tires. A warning is issued to alert
you to a decrease in pressure in one or
more of the tires. If the telltale illuminates continuous-
ly, one or more of your tires is signif-
icantly underinflated. There is no
malfunction in the TPMS.
If the telltale flashes for 60 seconds
and then stays illuminated, the TPMS
system itself is not operating proper-
ly.
iCanada only:
The Tire Pressure Monitoring System
(TPMS) is equipped with a low tire
pressure telltale in the instrument
cluster (
\2
page 20). If the telltale il-
luminates, one or more of your tires
is significantly underinflated.
Warning
G
The TPMS does not warn you against in-
correctly selected tire inflation pressure
and does not warn you when the tire pres-
sure is not properly selected for the re-
spective vehicle load. It warns you only
when the pressure of one or more tires
decreases significantly below the refer-
ence inflationpressure which was stored at the time of
calibration of the TPMS after you inflated
the tires.

pressure, as selected by the driver, in all
four tires. A warning is issued to alert
you to a decrease in pressure in one or

Tire pressure inquiries are made using

Press the

button until
the current inflation pressures for
each tire appear in the multifunction
display. If the telltale flashes for 60 seconds

iPossible differences between the
readings of a tire pressure gauge of
an air hose, e.g. gas station equip-
ment, and the vehicle’s control sys-
tem can occur. Usually the readings
issued by the control system are
more precise.

418 OperationCleaning and care of the vehicle
4
Automatic car washYou can clean the vehicle in an automat-
ic car wash from the very start. It is pref-
erable to use a car wash that does not
have brushes.
If the vehicle is very dirty, prewash it be-
fore you drive into the car wash.\1
Remove the radio / telephone anten-
na and fold the exterior mirrors in be-
fore driving into the automatic car
wash.For information on windshield wiper
switch, see the “Controls in detail” sec-
tion (
\2
page 210).
!
CAUTION
Make sure that the automatic car
w a s h i s s u i t a b l e f o r t h e s i z e o f t h e ve -
hicle.
If you do not remove the radio / tele-
phone antenna and fold in the exteri-
or mirrors, there is a possibility that
the antenna, the exterior mirrors or
the vehicle could be damaged by the
automatic car wash.
!
CAUTION
Make sure that the windshield wiper
switch is set to
0 (\2
page 210), oth-
erwise the rain sensor could be acti-
vated, for example, and the
windshield wipers could be triggered
unintentionally. This could cause
damage to the vehicle.
