If at any time you suspect that exhaust fumes are entering the
vehicle, have the problem checked and corrected as soon as pos-
sible. If you must drive under these conditions, drive only with allwindows fully open. Keep the trunk lid or rear gate closed while driving to prevent
exhaust gas from entering the vehicle.

bloodstream delays your reaction and impairs your perception,judgment and attentiveness. If you drive after drinking ± even ifyou drink just a little ± it will increase the risk of being involved ina serious or fatal accident, injuring or killing yourself, your pas-sengers and others. In addition, if you are injured in the accident,
alcohol may increase the severity of that injury. Please don't drink and drive.

There are some drugs (over the counter and prescription) that can delay your reaction time and impair your perception, judg-ment and attentiveness. If you drive after taking them, it may in-
crease your, your passengers' and other persons' risk of being

After p arking in d irec t sunlig ht, d rive with the wi nd ows op en for a few
minutes to allow outsid e air to c irc ulate into the heated interior. This
results in q uic ker c ooling b y the air c ond itioner. Keep the wind ows

Und er c ertain weather c ond itions (hig h relative hum id ity, low temp era-
tures, etc .) a small amount of water vap or emission from the air outlets
may b e notic ed . This c ond ition is normal and d oes n ot ind ic ate any
