(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter .
Indicator lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
functions.
With some indicator lights, messages may ap­pear and warning signals may sound. The indica­
tor lights and messages in the display can be cov­
ered by other displays. To show them again, se­ lect the tab for the indicator lights and messages
using the multifunction steering wheel
c;, page 19. If there are several malfunct ions,
you can display them one at a time using the
thumbwheel.
Some ind icator lights in the display can display in
several colors .
Overview
Some indicator lights turn on briefly as a function
check whe n you switch the ign ition on . These sys­
tems are marked with a
,I in the following tables.
If one of these indicator lights does not turn on,
there is a ma lfunction in that system.

_& WARNING
- Light bulbs a re under p ressure and can ex­

Driving
Avoid full acc ele ra tion
You sho uld rare ly travel at the maximum vehicle
speed . High speeds cause a disp roportionately
high increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the engi ne, for examp le when
at rai lro ad crossings or tr affic lights with longer
red lights . Stopping the engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to resta rt the engine.
It t akes a very long time in idle to wa rm the en­
g ine up to operating tempe ra ture . Wear and
emissions are especially high in the warm-up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have ma intenanc e performed r egularly
By having maintenance performed regular ly on
your vehicle, yo u can help to reduce f uel con­
sumpt ion before you even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l­
so impacts
fuel consumpt ion .
A poorly maintained engine can lead to fuel con­
sumpt ion that is 10% higher than normal.
A lso check the
oil le vel when refueling . The o il
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can o nly be properly judged after
approx imately 3,000 m i (S,000 km) have been
d riven.
Avoid short trips
The engine and exhaust cleaning system must
reach the ir opt imal
operating temperature to ef­
fectively red uce consumption and em iss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The engine reaches operating
temperature and consumpt io n normalizes only
afte r approximately
four kilometers.
56
(D Note
Do not leave engine idling unattended after
starting. If warning lights sho uld come on to
i ndicate imprope r operation, they would go
unheeded. Extended idling also produces
h eat, which could result in overheating or
other damage to the vehicle o r other proper­
ty.
(D Note
- Have your ve hicle ma intained properly and
in accordance with the service recommenda­
t ions i n your Warranty
& M aintenance book­
let. La ck of prope r mai nte na nce as we ll as
imp roper use o f the ve hicle will impa ir the
func tion of the emission cont ro l sys tem and
cou ld lead to damage.
- Do not alte r or remove any compone nt of
the Emission Contro l System unless ap ­
proved by the man ufacturer.
- Do not alte r or remove any dev ice, such as
heat shields, switches, ig nition w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
important veh icle components.
