OP-eration
The supply of a ir to the outlets is controlled either automat ically or
manually depend ing on the operation mode selected. The airflow
from all outlets can be heated, unheated or cooled .
The heater outlets for the rear footwells are located under the front
seats. When you select outlets@, air is also directed to the rear foot­
wells.
[I) Tips
• When defrosting/defogging the windows, air flows from outlets
(D ,@ and @. To defrost or defog the windows as rapidly as poss ible,
air outlets ® should be opened
fully with the adjuster wheels.
• When the air conditioner is working, cooled air w ill flow primarily
from outlets @,® and @. To assure adequate cooling, outlets ®
and © should never be completely closed.•
Using the climate controls economically
Using the climate controls prudently can help save fuel .
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should use
the air conditioner only when necessary. Also please note the
following points:
- If you want to save fuel, switch off the air conditioner .
- If you are going to drive with the windows open, switch off
the air conditioner.
By reducing the amount of fuel you use, you also reduce the amount
of polluta nts emitted into the air. •

must be connected to a 120 Volt Ground Fault Circuit (GFI) protected
outlet that is protected from water (in your garage, for instance).
When the coo lant is preheated, the engine reaches its operating
temperature more qu ickly and will use less fuel and produce fewer
polluting emissions during the warm-up phase.
Preheat ing the engine can take up to 3 hours depending on the
temperature outside.

a need for concern.
If the engine does not start immediately, stop try ing after 10 seconds
and then try to restart the engine about 30 seconds later .
Glow plug system*
Diesel engines are equipped with a glow p lug system whose
preheating t ime is con trolled by the coo la nt and outs ide tempera­

immediately af ter the glow p lug ind icator light
sw itches off .
Th e g low pl ug indica tor light w ill only ill uminate fo r approximately 1
second when the engine is warm or the outs ide temperature is higher
than 46 °F (8 °C). Tha t means yo u ca n sta rt the engi ne

To start the diesel engine after the fuel tank has
been run dry
If the fue l tank was run complete ly dry, the start ing process after
refueling with diesel fuel can take longe r than usual -up to one
minute. This is because the fuel system first has to be vented of air
wh ile starting. _,.

& WARNING (conti nu ed )
• Never tran sport object s larger than those fitting completely
into the luggage are a because the rear lid cannot be fully clos ed.
• If you absolutely must dri ve with the rear lid open , observe the
following note s to reduce the risk of po isoning:
- Clo se all windows,
- Close the power roof*,
- Open all air outlets in the instrument panel,
- Switch off the air recirculation ,
- Set the fresh air fan to the h ighest speed.
& WARNING
Always make sure that the doors , all windows, the power roof*
and the read lid are securely closed and lo cked to redu ce the ri sk
of inju ry when the vehicle is not being used.
• After closing the r ear lid, always make sure that it is properly
closed and locked.
• Never leave your vehicle unattended especially with the rear lid
left open. A child could crawl into the vehicle through the luggage
compartment and close the rear lid becoming trapped and unable
to get out. Being trapped in a vehicle can lead to serious personal
injury.
• Never let children play in or around the vehicle.
• Never let passengers ride in the luggage compartment . Vehicl e
occupants must alway s be properly restrained in one of the
vehicle 's seating positions.
00 Tips
• The tire pressu re mus t cor respond to the load - see the tire pres­
sure st icker on th e fuel filler doo r. •
The tire pressure must correspo nd to the load . The tire p ressure is
shown on t he tire press ure label. O n USA ve hicl es, t he tire press ure
label is located on the d river's s ide B-pillar. On Canada vehicles, the
tire press ure label is located either on the driver 's side B -pillar or
inside the fuel fille r flap . The t ire pressure labe l lists the recom­
mended co ld ti re inflation pressures for t he ve hicle at its maximum
c apacity weight and the tires that were on yo ur vehicle at the ti me it
was manufactured. For recommended tire pressures for normal load
c ondi tions, p le ase see cha pte r=>
page 249. •
Tie-downs
The lugg ag e co mportment is equipped with four tie­
downs to secure lugga ge and other items.
Use the t ie-downs to sec ure your ca rgo prope rly=> page 131,
"Loading the luggage compartment" .
In a co lli sion, t he laws of phys ics mean tha t even sma ller i tems th at
are loose in the vehicle will become heavy m issi les t hat can cause
ser ious injury. Items in the vehicle pos sess energy whi ch v ary wi th
vehicle speed and t he weight of the item. Vehicle speed is the most
significant factor .
For exampl e, in a fron tal col lis io n at a speed of 30 mp h (4 8 k m/h),
the forces actin g on a 10 -lb (4.S kg) o bject are about 20 times t he
normal weight o f the item. This means that the weig ht of the item
wou ld suddenly be abo ut 200 lbs. (90 kg) . You can imagine the inju­
r ies tha t a 200 lbs. (90 kg) i tem flying freely thro ugh t he p assenge r
compartment could cause in a collision like this.
& WARNING
Weak , damaged or improper straps used to secure items to t ie­
downs can fail during hard braking or in a collision and cause
ser ious personal injury.

Driving and environment
New brake pads have to be "burnished in" before they have optimal
grab ~& .
Dur ing the break-in period, you should avoid putting severe loads on
the bra kes. Severe loads incl ude, for example, sudden hard braking,
in part icu lar at very high speeds or, for examp le, on mountain passes .
& WARNING
Until they develop th e ma ximum "bite " for b est stopp ing pow er,
the surfaces on new brake pads require some "breaking-in" during
the in itial 100 to 150 mile s (150 to 200 kilometers ) of normal
city dr iving. You can compensate for this by p ress ing the brake
pedal more firml y. Thi s applies whenever n ew pads are in stalled .•
Driving through water on roads
---
N ote the following to avoid vehicle damage when driving through
water, fo r example on flooded roads:
• Th e wate r mus t not be any higher th an the bottom of the ve hicl e
body.
• Do not dr ive faster t han wal king speed.
& WARNING
After driving through water, mud , slush, etc ., th e brak es may be
slow to take effect because of wet brake rotors and pads . Dry the
brakes first by braking carefully to restore the full braking effect .
0 Note
Vehicle components such as the engine, transmission, suspension or
electrical system can be severely damaged by driving thro ugh water.
W Tips
• Check t he dept h of the wa ter before dr iv in g thro ugh it.
• Do not stop the vehicle, drive in reverse or sw itch the engine off
when driving through wate r.
• Keep in m ind t hat on coming vehicles may cre ate w aves t hat raise
the water level and make it too deep for your vehicle to drive thro ugh
safe ly.
• Avoid dr iv in g through sa lt water because it can cause corros ion. •
Catalytic converter
It is very important that y our emiss ion con trol system
(ca talyti c converte r) is func tioning pr operly to ensure
that your vehicle is running i n an environm entally sou nd
manner.
- Always use lead-fre e gasoline => page 219, "Fu el supply".
- Never run the ta nk down a ll the way to empty .
- Never p ut too much mo tor o il in your engine=>
pag e 232,
"Adding engine oil~" -
- Neve r try to pu sh- or tow-start you r vehicle.
T he catalytic converter is an efficient "clean- up" device b uilt into the
exhaust system of the veh icle. The cata lytic converter b urns many of
t he poll uta nts in the e xhaust g as before they are released in to the
atmosphe re.
Th e ex clusive use o f unleaded fuel is c ritic ally impor tant for the life of
the cata lytic converte r and proper f unction ing of the engi ne. ..,
