T
he instrument cluster and center conso le illum ination (gauges and
need les) comes o n when you sw itch on the ign ition and the
vehicle
headlights are off .
Be aware of the following d ifference between
mode ls built to US o r Canadian specifications :
• USA models : illumination of the instrument cluster (gauges and
needles), da sh and c enter console around the g earshift lever is
controlled by a light sensor located in the instrument panel. The
instrum ent panel illumination will automat ically become dimmer
as the d aylight fades awa y and eventually will go out completely
when out side light i s very low . Th is is to remind you, the driver , to
switch on the headlights before it gets too dark .
• Canada models: instrument panel illumin ation will stay bright
r egardless of the intensity of ambient light. Always be awa re of
change s in out side light condition s while you are driving. Re spond
i n time to f ading daylight by turning the light sw itch to position
j D
(or "AUTO " if your car is eq uipped w ith this fea ture) to turn on your
headlights. •
Tachometer (engine rev counter)
The tachometer indica tes the engine RP M (revolutions
per minutes) .
The tachomete r© ::::, fig . 2 is the left one of the two large clo ck-type
displays .
The engine turns at a speed 1 000
times the single digit in the
display, e .g . if the need le points at the "2", the engine tu rns at
2 000 RPM .

If the engine RPMs drop below 1 500, you should downshift to the
next lower gear. The red area at the end of the scale indicates
maximum permissible engine RPMs after the break-in period. Before
reach ing this area, you should either shift into the next higher gear or
ease your foot off the accelerator pedal.
0 Note
The tachometer needle=> page 8, fig. 2 © should not move into the
red range. If it does, then only for a very short period of time. You
could damage your engine by driv ing at high RPM!
<£> For the sake of the environment
Upshifting early saves fuels and reduces engine noise. •

Instruments and warning/indicator lights
Engine cold
As long as the need le remains at the lef t en d of the gauge, the engine
s till has not reac hed its operati ng te mperature . Avoid hig h eng ine
speeds, heavy engine loads a nd heavy throttle.
Normal temperature
W hen the eng ine has reached its operating temperature, the need le
w ill move into the middle of the gauge and rema in there . If the
engine is working ha rd at high outsi de temperatures, the needle may
tur n further to the rig ht. Thi s is no cause fo r concern as long as the _F_
wa rning light in the i nstr ument cluster does not ill uminate.
Wh en the _;_ w ar ning light sta rts to fla sh, thi s can mea n one of two
things : either the coolant
temperature is too h igh, or t he coolant
level is too low => page 32.
& WARNING
• Always observe the warning in=> page 218, "Engine com part·
ment " before opening the engine hood and checking the engine
c oolant level.
• Never open the engine hood if you see or hear steam, or if you
see engine coolant dripping from the engine compartment. You
could burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant.

[ i ] Tips
• The engine oil pressure symbol 'I=:?: is not an indic ato r for a low
engine oil level. Do not rely on it . Instead , check the oil level in your
engine at regular intervals , preferably each t ime you refuel, and
always before going on a long tr ip .
• The yellow oil level warning indication requires oil refill or
workshop service without de lay . Do not wait until the red oil pre s­
