If the ENGINE OVERHEATED
STOP ENGINE or the ENGINE
OVERHEATED IDLE ENGINE
message appears with no sign of
steam, try this for a minute or so:
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine
idle in N (Neutral) while stopped.
If it is safe to do so, pull off
the road, shift to P (Park)
or N (Neutral) and let the
engine idle.
If the temperature overheat gauge
is no longer in the overheat zone
or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull
over, stop, and park the vehicle
right away.
If there is no sign of steam, idle
the engine for five minutes while
parked. If the warning is still
displayed, turn off the engine
until it cools down. Also, see
“ Overheated Engine Protection
Operating Mode ” later in this
section.
Overheated
Engine Protection
Operating Mode If an overheated engine condition
exists and the ENGINE POWER IS
REDUCED message is displayed,
an overheat protection mode which
alternates firing groups of cylinders
helps prevent engine damage. In this mode, a loss in power and
engine performance will be noticed.
This operating mode allows the
vehicle to be driven to a safe place
in an emergency. Driving extended
distances and/or towing a trailer in
the overheat protection mode
should be avoided.
Notice: After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to cool
before attempting any repair.
The engine oil will be severely
degraded. Repair the cause of
coolant loss, change the oil and
reset the oil life system. See
Engine Oil on page 10 ‑ 7 .
Engine Fan The vehicle has electric cooling
fans. The fans spinning at low
speed during most everyday
driving might be heard. The fans
can turn off if no cooling is required.

Vehicle Care 10-23Under heavy vehicle loading,
trailer towing, and/or high outside
temperatures, or if operating the
air conditioning system, the fans
can change to high speed and an
increase in fan noise might be
heard. This is normal and indicates
that the cooling system is
functioning properly. The fans
change to low speed when
additional cooling is no longer
required.
Power Steering Fluid
See Engine Compartment Overview
on page 10 ‑ 6 for reservoir location. When to Check Power Steering
Fluid It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid To check the power steering fluid:
1. Turn the key off and let the
engine compartment cool down.
2. Wipe the cap and the top of the
reservoir clean.
3. Unscrew the cap and wipe the
dipstick with a clean rag.
4. Replace the cap and completely
tighten it.
5. Remove the cap again and look
at the fluid level on the dipstick. The level should be at the FULL
COLD mark. If necessary, add only
enough fluid to bring the level up to
the mark.
What to Use To determine what kind of fluid to
use, see Recommended Fluids and
Lubricants on page 11 ‑ 7 . Always
use the proper fluid.
Notice: Use of the incorrect fluid
may damage the vehicle and the
damages may not be covered by
the vehicle's warranty. Always
use the correct fluid listed in
Recommended Fluids and
Lubricants on page 11 ‑ 7 .

Vehicle Care 10-25
{ WARNINGThe brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair.
Some driving conditions or climates
can cause a brake squeal when
the brakes are first applied or
lightly applied. This does not mean
something is wrong with the brakes. Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in
the proper sequence to torque
specifications in Capacities and
Specifications on page 12 ‑ 2 .
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a
sign that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear. Replacing Brake System Parts The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes — for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.

10-54 Vehicle Care If you overfill the tire, release air
by pushing on the metal stem
in the center of the tire valve.
Recheck the tire pressure with
the tire gauge.
Be sure to put the valve caps
back on the valve stems. They
help prevent leaks by keeping
out dirt and moisture.
Tire Pressure for
High-Speed Operation
{ WARNING
Driving at high speeds, 160 km/h
(100 mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat build up
and can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
(Continued) WARNING (Continued) inflation pressure adjustment for
high speed operation. When
speed limits and road conditions
are such that a vehicle can be
driven at high speeds, make sure
the tires are rated for high speed
operation, in excellent condition,
and set to the correct cold tire
inflation pressure for the
vehicle load.
If your vehicle has P265/65R18 or
P285/45R22 size tires and you will
be driving at high speeds, speeds of
160 km/h (100 mph) or higher, set
the cold inflation pressure to 20 kPa
(3 psi) above the recommended tire
pressure shown on the Tire and
Loading Information Label. When
you end this high ‐ speed driving,
return the tires to the cold inflation
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9 ‑ 24
and Tire Pressure on page 10 ‑ 52 .Tire Pressure Monitor
System The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)

10-56 Vehicle Care
Tire Pressure Monitor
Operation If the vehicle is a hybrid, see
the hybrid supplement for more
information.
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The 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
and wheel assembly. The TPMS
sensors monitor the air pressure
in the tires and transmit the 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 on the instrument cluster.
If the warning light comes on, stop
as soon as possible and inflate
the tires to the recommended
pressure shown on the tire loading
information label. See Vehicle Load
Limits on page 9 ‑ 24 .
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). The low
tire pressure warning light and the
DIC warning message come on at
each ignition cycle until the tires
are inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed.
For additional information and
details about the DIC operation
and displays see Driver Information
Center (DIC) on page 5 ‑ 26 and Tire
Messages on page 5 ‑ 39 .
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information
label shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9 ‑ 24 , for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10 ‑ 52 .
The TPMS can warn about a
low tire pressure condition but
it does not replace normal tire
maintenance. See Tire Inspection
on page 10 ‑ 58 , Tire Rotation on
page 10 ‑ 59 and Tires on
page 10 ‑ 46 .
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using an
incorrect tire sealant is not
