Possible cause
Low tire pressure
warning light
Make sure tires are at the proper pres-
sure. See Inflating your tires in this
chapter. After inflating your tires to the
manufacturer’s recommended pressure
as shown on the Tire Label (located on
the edge of driver ’s door or the B-Pillar),
the vehicle must be driven for at least
two minutes over 20 mph (32 km/h)
before the light turns off.
Tire(s) under-inflated
Solid warning light
If the tires are properly inflated and the
light remains on, contact your authorized
dealer as soon as possible.
TPMS malfunction
If the tires are properly inflated and the
light remains on, contact your authorized
dealer as soon as possible.

When Inflating Your Tires
Note: Do not use the tire pressure display
screen as a tire pressure gauge, this can
result in over or under inflation of a tire.
When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.
It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. When driving in a normal manner, a
typical passenger tire inflation pressure
may increase about
2 –4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
62.6°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.

Oils and Fluids
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair.
NORMAL SCHEDULED MAINTENANCE

Change the oil and filter.
Inspect the tires and check the tire pressures.
Inspect the brake pads, rotors, hoses, brake cooling duct hoses and check the parking
brake function. Check the brake fluid level.
Inspect the engine cooling system strength and hoses. Check the coolant level.
Inspect the exhaust system and heat shields.
Inspect the accessory drive belts.
Inspect the steering linkage, ball joints, suspension and the tie-rod ends.
Inspect the wiper blades. Check the washer fluid level.
Inspect the hinges and latches. Lubricate if needed.
Inspect the vehicle battery and the state of charge.
Check the hydraulic fluid level.
Check the operation of all the lights.
Check the operation of warning indicators inside the instrument cluster.
Check for any fluid leaks.
