(D Tips
-Depending on vehicle equipment, the in ­
str ument ill umination (need les and gauges)
may t urn on when the lights are off and the
i gnition is sw itched on. The illumination for
t h e gauges reduces automat ica lly and even­
tua lly turns off as br ightness outside in­
creases . This func tion rem inds the dr iver to

Coolant temperature indicator
The coolant temperatu re display (D ¢ page 10,
fig. 4
or ¢ page 10, fig . 3 only functions when
the ignition is switc hed on . To prevent engine
damage, please observe the following notes
about the temperature ranges.
Cold rang e
If onl y the L EDs at the bottom o f th e ga uge tu rn
on, the engine has not reached operating tem ­
pe rature yet. Avoid high engine speeds, full ac ­
celerat ing and heavy engine loads .
Normal range
The engine has reached its oper ating temper a­
ture once the LEDs up to the center o f th e ga uge
turn on. If
the . indicator lig ht in the instru­
ment cluster display turns on, the coolant tern -
~ perature is too high ¢ page 25 .

the risk of the engine overheating dur ing
hig h outside temperat ures and heavy en­
gine load .
-The front spoi ler a lso helps to distribute
cooling a ir correctly while driv ing. If the
spoiler is damaged, the coo ling effec t w ill

-Vehicles without a coolant temperature dis­
play: to promote a lo ng e ngine serv ice li fe,
a voiding h igh engine spee ds, full acce lera ­
tion and heavy engine loads during app rox i­
mate ly the first 15 minutes when the en ­
gine is cold is recommended. The amount of
t ime that the eng ine is co ld depends on the
outside temperature.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
T he beginning of t he red zone in the tachometer
indicates the maxim um permissible engine speed
for all gea rs once the engine has bee n broken in
and when it is warmed up to operating tempera­
ture . Before reach ing the red zone, you sho uld
sh ift into the next h igher gear, choose the "D" or
" S" se lecto r lever pos it io n, or remove yo ur foot
from the ac cele ra tor ped al.

CD Note
The needle in the tachometer @ Q page 10,
fig. 4 or¢ page 10, fig. 3 may only be in the
red area of the gauge for a short time or there
is a risk of engine damage. The location where
the red zone beg ins varies depending on the
eng ine .
@ For the sake of the environment
Upshifting early helps you to save fuel and re­
duces operating noise .
Fuel level
The display@¢ page 10, fig. 4 or ¢ page 10,
fig. 3 only functions when the ign ition is swi tch­
ed on . When the display has reached the reserve
mark, a red LED appe ars and the
rD indica to r
light t urns on ¢
page 28. The LED blinks red
when the f uel level is very low .
For the tank capacity in yo ur vehicle , refer to the
Te chnical Data
¢ page 38 2.
CD Note
Never d rive until the tank is comple tely emp­
t y. The irregular supp ly of fuel that resul ts
from that can ca use engine misfi res . U ncom­
bus ted fuel will the n enter the e xhaus t sys ­
tem . This can cause overheating and damage
to the cata lytic conve rter .

Trip odometer and odometer
The trip odometer shows the dis tance driven
s ince it was last reset. It can be used to measure
short d istances.
The trip odometer ca n be reset to zero by p ress­
i ng t he rese t button ®¢
page 10, fig. 4 or
¢page 10, fig. 3.
The odometer shows the total d istance that t he
vehicle has been drive n.
Malfunction indicator
If there is a malfunction in the instrument clus­
te r,
DEF will appear in the trip odome ter display .
Have the malfunction corrected as soon as possi­
ble.
Outside temperature display
If your vehicle i s sta tionary or if yo u are driv ing at
very low speeds, t he temperature d isplayed may
be slight ly higher than the actual temperatu re
outside due to the heat radiating from the en ­
gine .
At temperatures be low 41 °F (+S °C), a snowf lake
symbol appears in front of t he temperature dis­
play ¢.&. .
A WARNING
Do not assume the roads are free of ice based
on the outside tempe rature disp lay. Be aware
that t here may be ice on roads even when the
outside temp erature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents .

zero, press and hold the left thumbwhee l on
the m ultif unct ion steer ing whee l for one sec­

to fuel consumption and shows other equipment i n fluencing consumption. Economy t ips provide
adv ice for efficient driving .
T he efficiency program receives distance and con ­
sumpt ion data from the short-term memory. If
the data in the effic iency program is deleted, the
va lues in the s hort -term memory are also reset .
T he fo llow ing additional displays may be availa­

cle equipment:
- Other equipment : other equipment that is cur­
rently affecting fue l consumption is listed in
the efficiency program. The d isp lay shows up to
