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.
DRINKING AND DRIVING WARNING
Drinking and then driving is very dangerous. Alcohol in the
bloodstream delays your reaction and impairs your perception,judgment and attentiveness. If you drive after drinking – even if
you drink just a little – it will increase the risk of being involved in
a 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.
Drunken d riving is one of the most freq uent c auses of ac c id ents. Sinc e
alc ohol affec ts all p eop le d ifferently, you may hav e c onsumed too muc h
alc ohol to d rive safely even if the level of alc oho l in your b lood is b elow
the leg al limit. The safest thing you c an d o is nev er d rink and d rive. How-
ever if you have no c hoic e b ut to d rive, stop d rink ing and sob er up c om-
p letely b efore g etting b ehind the wheel. DRUGS AND DRIVING
WARNING
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
involved in a serious or fatal accident.
