Pressure Cap
Notice:If the pressure cap is not
tightly installed, coolant loss
and possible engine damage may
occur. Be sure the cap is
properly and tightly secured.
SeeEngine Compartment Overview
on page 9-6for more information
on location.
Engine Overheating
There is an engine coolant
temperature warning light on
your vehicle’s instrument panel.
SeeEngine Coolant Temperature
Warning Light on page 4-19for
more information.
If Steam Is Coming From
Your Engine
{CAUTION
Steam from an overheated
engine can burn you badly,
even if you just open the hood.
Stay away from the engine if
you see or hear steam coming
from it. Just turn it off and
get everyone away from the
vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you
open the hood.
If you keep driving when your
engine is overheated, the
liquids in it can catch re.
You or others could be badly
burned. Stop your engine if it
overheats, and get out of the
vehicle until the engine is cool.Notice:If the engine catches re
because of being driven with
no coolant, your vehicle can be
badly damaged. The costly
repairs would not be covered by
the vehicle warranty.
If No Steam Is Coming From
Your Engine
An engine coolant temperature
warning can indicate a serious
problem. SeeEngine Coolant
Temperature Warning Light on
page 4-19.
If you get an engine coolant
temperature warning, but see or hear
no steam, the problem may not be
too serious. Sometimes the engine
can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.

Tire Pressure Monitor
Operation
The Tire Pressure Monitor System
(TPMS) is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and
wheel assembly, excluding the
spare tire. The TPMS sensors
monitor the air pressure in the
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.The low tire pressure warning light
comes on at each ignition cycle
until the tires are in ated to
the correct in ation pressure.
The low tire pressure warning light
may come on in cool weather
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 in ated
to the proper pressure.
You must begin driving before the
TPMS system is operational.
TPMS sensors need to be installed
onto the full-size tire and wheel
assemblies, and the tires adjusted
to the manufacturers’ recommended
tire pressure amount.
A Tire and Load Information label is
attached to the vehicle, and shows
the size of the vehicle’s original
equipment tires and the correct
in ation pressure for the tires when
they are cold. SeeLoading the
Vehicle on page 8-30, for anexample of the Tire and Load
Information label and its location on
the vehicle. Also seeInflation - Tire
Pressure on page 9-46.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. SeeTire Inspection
and Rotation on page 9-51andTires
on page 9-38.
Notice:Liquid tire sealants
could damage the Tire Pressure
Monitor System (TPMS) sensors.
Sensor damage caused by
using a tire sealant is not covered
by your warranty. Do not use
liquid tire sealants.
Each TPMS sensor has a unique
identi cation code. Any time
you replace one or more of the
TPMS sensors or rotate the
vehicle’s tires, the identi cation
codes are automatically learned by
the TPMS. This occurs within a
few moments of driving the vehicle
over 19 mph (31 km/h).
