and humanity intoaccount.
You toocan help toprotect theenvironm ent
by operating yourvehicle inan environm en-

R operating conditionsof your vehicle
R your personal drivingstyle
You caninfluence bothfactors. Youshould
bear thefollowing inmind:
Operating conditions:
R avoid shorttripsasthese increase fuel
consumpt ion.
R alwa ysmake surethatthetire pressures
are correct .
R do not carry anyunnecessary weight.
R remove roofracks onceyounolonger

Personal drivingstyle:
R do not depress theaccelerator pedal
when startin gthe engine.
R do not warm upthe engine whenthevehi-

R drive carefully andmaintain asafe dis-
tance fromthevehicle infront .
R avoid frequent, suddenacceleration and
braking. R

determine andsetthe correct tirepressure,
proceed asfollows:
X Remove thevalve capofthe tire that isto
be checked.
X Press thetire pressure gaugesecurely onto
the valve.
X Read thetire pressure andcompare itto the
recommended valueonthe Tire andLoading
Information placardorthe tire pressure
table (Ypage 299).
X Ifthe tire pressure istoo low, increase the
tire pressure tothe recommended value.
X Ifthe tire pressure istoo high, release air.
To do so, press downthemetal pininthe
valve, usingthetipofapen forexample.
Then check thetire pressure againusing the
tire pressure checker.
X Screw thevalve caponto thevalve.
