Maintenance and care

The prescribed service interval is based on
normal vehicle use. Service work will need to
be performed more frequently than prescribed
if the vehicle is operated under more arduous
conditions or with higher loads. Such arduous
conditions include:
R regular city driving with frequent intermedi-
ate stops
R driving predominantly short distances
R frequent operation in mountainous terrain or
on poor road surfaces
R leaving the engine idling for long periods on
a frequent basis
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for exam-
ple, replaced more frequently. Under more

Maintenance and care

!
Secure the tow rope or tow bar to the tow-
ing eye or trailer tow hitch only. Otherwise,
the vehicle could become damaged.
! Do not use the towing eye for recovery,
this could damage the vehicle. If in doubt,
recover the vehicle with a crane.
! Drive slowly and smoothly when towing.
Excessive tractive power could otherwise
damage the vehicles.
! Shift the automatic transmission to posi-
tion i and do not open the driver's or front
passenger's door during towing. The auto-
matic transmission may otherwise shift to
position j, which could damage the trans-
mission.
! You may tow the vehicle for a maximum
distance of 30 miles (50 kilometers). A tow-
ing speed of
30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 kilometers), the entire vehicle must be
raised and transported.
When towing away, you must observe the legal
requirements for the country in which you are
currently driving.
It is better to have the vehicle transported
than to have it towed.
Have the vehicle transported on a transporter
or trailer if it has transmission damage.
The automatic transmission must be in posi-
tion i when the vehicle is being towed away.
If the automatic transmission cannot be shif-
ted to position i, have the vehicle transpor-
ted on a transporter or trailer.

Important safety notes G
WARNING
Risk of accident due to incorrect tire
pressure
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommen-
ded by the vehicle manufacturer on the vehi-
cle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than
the size indicated on the vehicle placard or
the 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 monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a signifi-
cantly under-inflated 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 han-
dling and stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver's responsibility to maintain cor-
rect 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 illumina-
ted, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the
vehicle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction telltale
after replacing one or more tires or wheels
on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the
TPMS to continue to function properly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pres-
sure suitable for the operating conditions
(Y page
282).
Note that the correct tire pressure for the cur-
rent operating conditions must first be pro-
gramed into the tire pressure monitor. If a sub-
stantial pressure loss occurs, the warning
threshold for the warning message is aligned
to the taught-in reference values. Restart the
tire pressure monitor after adjusting the cold
tire pressure ( Y page 288). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tire pressure drops significantly.
The tire pressure monitor does not warn you if
a tire pressure is incorrect. Observe the notes
on the recommended tire pressure
(Y page 282).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. following
penetration by a foreign object. In this event,
brake the vehicle until it comes to a standstill.
Avoid sudden steering movements.
The tire pressure monitor has a yellow h
warning lamp in the instrument cluster for indi-
cating pressure loss/malfunctions (USA) or
pressure loss (Canada). Depending on how the
warning lamp flashes or lights up, an underin-
flated tire or a malfunction in the tire pressure
monitor is displayed:
R if the h warning lamp is lit continuously,
the tire pressure on one or more tires is sig- 286
