Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure
to read the manufacturer’s instructions before
use. If you will be operating your vehicle in an area
where the temperature may fall below freezing,
use a uid that has sufficient protection against
freezing.
Adding Washer Fluid
When the windshield washer uid is low, a low
washer uid light may appear on the instrument
panel cluster. SeeLow Washer Fluid Warning
Light on page 197for more information.
In addition, if your vehicle has a Driver Information
Center (DIC), the LOW WASHER FLUID
message will display when the uid level is low.
SeeDIC Warnings and Messages on page 208
for more information.Open the cap with the
washer symbol on it.
Add washer uid until
the tank is full. See
Engine Compartment
Overview on page 350
for reservoir location.
Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing
occurs, which could damage the tank if
it is completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. TPMS sensors are mounted onto each
tire and wheel assembly, except for the spare tire.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure
readings to a receiver located in the vehicle.
When a low tire pressure condition is detected,
the TPMS illuminates the low tire pressure
warning light, located in the instrument panel
cluster. If your vehicle has the uplevel Driver
Information Center (DIC), a warning message to
check the pressure in a specic tire displays at
the same time the low tire pressure warning light
comes on. The low tire pressure warning light
and the DIC warning message CHECK TIRE
PRESSURE come on at each ignition cycle
until the tires are inated to the correct
ination pressure. Vehicles that have the
uplevel DIC buttons can also check tire
pressure levels by pressing the gages button.For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 200andDIC Warnings and
Messages on page 208.
During cooler weather conditions, the low tire
pressure warning light and the DIC warning
message, if your vehicle has this feature, may
come on when the vehicle is rst started, and then
turn off as you start to drive. This could be an
early indicator that the air pressure in the tire(s)
are getting low and need to be inated to the
proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated
to the ination pressure recommended by the
vehicle manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire ination pressure label,
you should determine the proper tire ination
pressure for those tires.)

When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
A tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct ination
pressure for your vehicle’s tires when they
are cold. SeeLoading Your Vehicle on page 319,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also seeInation - Tire Pressure on page 409.
Your vehicle’s TPMS system can warn you
about a low tire pressure condition but it does
not replace normal tire maintenance. See
Tire Inspection and Rotation on page 416and
Tires on page 402.Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
When the system detects a missing or inoperable
sensor, an error message SERVICE TIRE
MONITOR SYSTEM appears on the DIC display,
if your vehicle has this feature. If you have
replaced a tire/wheel assembly without transferring
the TPMS sensors, the error message displays.
Once you re-install the TPMS sensors, the
error message should go off. See your dealer for
service if all TPMS sensors are installed and
the error message comes on and stays on.
