WARNING
Driving when your engine is overheated can cause some fluids which may have leaked into
the engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle until the engine has cooled down.
! Among other possible causes, the poly-V-belt could be broken. Do not continue to
drive.
Otherwise, the engine will overheat due to an inoperative water pump which may
result in damage to the engine. 170

Tire Pressure Monitoring System (TPMS)*
Problem Possible causes/consequences and
M Solutionsh
The yellow
combination
low tire
pressure/TPMS
malfunction
telltale
illuminates
continuously. The TPMS detects a loss of pressure in at least one tire.
X
Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. Observe the traffic
situation around you.
X Check and correct tire inflation pressure as required
(Y page 126).
If the tire inflation pressure in the respective tire(s) has
(have) been corrected, the combination low tire pressure/TPMS
malfunction telltale goes out after a few minutes of driving.
See also “Restarting the TPMS” (Y page 129). h
The
combination
low tire
pressure/TPMS
malfunction
telltale flashes
60 seconds and
then stays
illuminated. There is a malfunction in the TPMS.
X
Have the TPMS checked at an authorized smart center.
After the malfunction has been remedied the combination low
tire pressure/TPMS malfunction telltale goes out after a few
minutes of driving. G
WARNING
Each tire should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the Tire and Loading Information placard. If
your vehicle has tires of a different size than the size indicated on the Tire and Loading
Information placard, 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.
Underinflation 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 underinflation 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 172
What to do if ...
>> Practical hints.
* optional

low tire pressure telltale. When the system detects a malfunction, the telltale will flash for
approximately 1 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
incompatible 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. Warning and indicator lamps in the overhead control panel

About replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is
therefore

essential that all bulbs and lamp
assemblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized smart center for headlamp
adjustment. G
WARNING
Bulbs and bulb sockets can be very hot.
Allow
the lamp to cool down before changing
a bulb. Otherwise you could be burned if you
touch them.
Keep bulbs out of the reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
i If the headlamps or front fog lamps* are
fogged up on the inside as a result of
high humidity, driving the vehicle a
distance with the lights on should clear
up the fogging.
Notes on bulb replacement:
R Only use bulbs of the same type and with
the specified watt rating.
R Switch the lights off before replacing a
bulb to prevent short circuits.
R Always use a clean lint-free cloth when
handling bulbs.
R Your hands should be dry and free of oil
and grease.
R Avoid touching the glass of the bulb with
bare fingers.
R If the newly installed bulb does not come
on, contact an authorized smart center.
R Have the bulbs for the front fog lamps*
and the LED daytime running lamps*
replaced at an authorized smart center.178
