charger on the 12-volt AGM
battery, some chargers have
an AGM battery setting on the
charger. If available, use the
AGM setting on the charger,
to limit charge voltage to

.Reduced fuel economy
for internal combustion
engine vehicles
.Reduced range for
electric vehicles
Overinflated tires, or tires
that have too much air,
can result in:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from
road hazards
The Tire and Loading
Information label on the
vehicle indicates the
original equipment tires
and the correct cold tire
inflation pressures. The recommended pressure is
the minimum air pressure
needed to support the
vehicle's maximum load
carrying capacity. See
Vehicle Load Limits
0242.
How the vehicle is loaded
affects vehicle handling
and ride comfort. Never
load the vehicle with more
weight than it was
designed to carry.
When to Check
Check the pressure of the
tires once a month or more.
Do not forget the spare,
if the vehicle has one. The
compact spare cold tire
pressure should be at
420 kPa (60 psi). See
Compact Spare Tire 0404. How to Check
Use a good quality
pocket-type gauge to
check tire pressure. Proper
tire inflation cannot be
determined by looking at
the tire. Check the tire
inflation pressure when the
tires are cold, meaning the
vehicle has not been driven
for at least three hours or
no more than 1.6 km (1 mi).
Remove the valve cap from
the tire valve stem. Press
the tire gauge firmly onto
the valve to get a pressure
measurement. If the cold
tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label,
no further adjustment is
necessary. If the inflation

following on lamp covers:
.Abrasive or caustic agents.
.Washer fluids and other
cleaning agents in higher
concentrations than
suggested by the
manufacturer.
.Solvents, alcohols, fuels,
or other harsh cleaners.
.Ice scrapers or other hard
items.
.Aftermarket appearance
caps or covers while the
lamps are illuminated, due to
excessive heat generated.
Caution
Failure to clean lamps
properly can cause damage
to the lamp cover that would
not be covered by the
vehicle warranty.
Caution
Using wax on low gloss black
finish stripes can increase
the gloss level and create a
non-uniform finish. Clean low
