Temperature Warning
Light
This light comes on briefly while
starting the vehicle.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light goes off.
{Caution
The engine coolant temperature
warning light indicates that the
vehicle has overheated. Driving
with this light on can damage the
engine and it may not be covered
by the vehicle warranty. See
Engine Overheating on
page 10-16.
The engine coolant temperature

9-6 Driving and Operating
Warning (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10-26.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.

9-8 Driving and Operating
Warning (Continued)
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the(Continued)
Warning (Continued)
vehicle and set the fan speed
to the highest setting. See
“Climate Control Systems.”
For more information about
carbon monoxide, see Engine
Exhaust on page 9-17.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See Traction
Control/Electronic Stability Control
on page 9-25.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).

2. Pull the parking brake handle upuntil you can press the release
button.
3. Hold the release button in as you move the brake handle all
the way down.
{Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Parking Brake Break-in
Break-in the brake shoes whenever
the effect of the parking brake is
weakened or whenever the brake
shoes and/or drums are replaced, in
order to assure the best brake
performance. This procedure can be
performed at the dealer.
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and Electronic
Stability Control, an electronic
stability control system. These
systems use various sensors to
monitor driver inputs and vehicle
motion. Under certain driving
conditions, the TCS and Electronic
Stability Control systems help to
perform the following functions:
.Control brake pressure to reduce
wheel slip on one slipping drive
wheel so power is transferred to
a non–slipping drive wheel on
the same axle.
.Control brake pressure and
engine output to reduce drive
wheel slip based on vehicle
speed (traction control function).
.Control brake pressure at
individual wheels and engine
output to help the driver maintain
control of the vehicle in the
following conditions:
‐ Understeer (vehicle tends to
not follow the steered path
despite increased steering
input)
‐ Oversteer (vehicle tends to
spin due to certain road or
driving conditions)
TCS and Electronic Stability Control
can help the driver to maintain
control of the vehicle, but cannot
prevent loss of vehicle control in all
driving situations.
When the TCS and Electronic
Stability Control systems operate,
the
dindicator in the instrument
cluster flashes to note the following:
.The road may be slippery or the
system may determine some
action is required to help keep
the vehicle on the steered path.

Vehicle Care 10-13
{Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when you are driving.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.
1. Coolant Recovery Tank2. Radiator Pressure Cap
3. Engine Cooling Fans (Out
of View)
{Warning
An electric engine cooling fan can
start even when the engine is not
running. To avoid injury, always
keep hands, clothing, and tools
away from any engine
cooling fan.
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
{Caution
Using coolant other than the
recommended engine coolant can
cause premature engine, heater
core, or radiator corrosion. In
addition, the engine coolant could
require changing sooner. Any
repairs would not be covered by
the vehicle warranty. Always use
the recommended engine coolant.
See Recommended Fluids and
Lubricants on page 11-11.
Engine Coolant
The cooling system in the vehicle is
filled with long life antifreeze
coolant. See Recommended Fluids
and Lubricants on page 11-11.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating on
page 10-16.

10-14 Vehicle Care
What to Use
{Warning
Adding water or some other liquid
to the cooling system can be
dangerous. Water and other
liquids can boil before the proper
coolant mixture will. The coolant
warning system is set for the
proper coolant mixture. With
water or the wrong mixture, the
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use the recommended
engine coolant. See
Recommended Fluids and
Lubricants on page 11-11.Use the recommended engine
coolant. See
Recommended Fluids
and Lubricants on page 11-11.
If using this coolant, nothing else
needs to be added. This coolant:.Gives freezing protection down
to −37°C (−34°F), outside
temperature.
.Gives boiling protection up to
129°C (265°F), engine
temperature.
.Protects against rust and
corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
{Caution
If the improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
(Continued)
Caution (Continued)
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
recommended engine coolant for
the cooling system. See
Recommended Fluids and
Lubricants on page 11-11.
Never dispose of engine coolant by
putting it in the trash, by pouring it
on the ground, or by pouring into
sewers, streams, or bodies of water.
Have the coolant changed by an
authorized service center, familiar
with legal requirements regarding
used coolant disposal. This will help
protect the environment and your
health.

Vehicle Care 10-15
Checking Engine Coolant
Level
{Warning
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
{Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.
The vehicle must be on a level
surface when checking the coolant
level.
Check the coolant level in the
reservoir when the engine is cold.
If the coolant level is below the MIN
level, add coolant to the MAX level.
If the reservoir is empty, check the
coolant level in the radiator when
the engine is cold. If there is
insufficient coolant in the radiator, fill
the radiator with coolant up to the
filler opening and also add it to the
reservoir up to the MAX level.
The vehicle contains long life
coolant. The life expectancy of the
factory-fill coolant is 168,000 km
(105,000 miles) or seven years.
Mixing any other type of coolant or
the use of non-distilled water will
reduce the life expectancy of the
factory-fill coolant. Refer to the
Recommended Fluids and
Lubricants on page 11-11 for more
details.
The engine coolant reservoir is a
pressurized tank. When installing
the cap, tighten.

7707496) - 2015 - CRC - 11/26/14
10-16 Vehicle Care
If the cooling system frequently
requires coolant, have it checked by
your dealer.
Changing Engine Coolant
A dealer can change the engine
coolant. The service procedure can
be found in the service manual. See
Service Publications Ordering
Information on page 13-11.
Improper servicing can result in
reduced heater performance and
engine overheating.
{Warning
.To avoid the danger of being
scalded, never change the
coolant when the engine
is hot.
.Never remove the radiator or
engine coolant reservoir cap
when the engine is hot.
Serious burns could be
caused by high pressure fluid
escaping from the radiator.(Continued)
Warning (Continued)
.Avoid direct skin contact with
used coolant. If skin contact
is made, wash thoroughly
with soap or hand cleaner as
soon as possible.
.Keep coolant out of the reach
of children and pets.
Engine coolant must be disposed of
properly. Check your local
regulations.
Engine Overheating
The vehicle has an engine coolant
temperature warning light on the
instrument cluster to warn of engine
overheating. See Engine Coolant
Temperature Warning Light on
page 5-17.
If the decision is made not to lift the
hood when this warning appears,
but instead get service help right
away, see Roadside Assistance
Program on page 13-5. If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
See if the engine cooling fan speed
increases when idle speed is
doubled by pushing the accelerator
pedal down. If it does not, the
vehicle needs service. Turn off the
engine.{Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.

Vehicle Care 10-17
If Steam is Coming from the
Engine Compartment
{Warning
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 the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
Overheated Engine
Protection
Operating Mode
The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level:
.The engine coolant temperature
warning light will illuminate.
.Engine power may be reduced.
.The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).
Engine power and under certain
conditions, vehicle speed will
decrease. Vehicle speed can be
controlled with the accelerator
pedal, but the vehicle may not
accelerate at the desired speed. The transmission will downshift or
upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and
engine coolant temperature is
reduced, vehicle speed can be
increased using the accelerator
pedal, and air conditioning cooling
function will automatically be turned
back ON.
If:
1. The engine coolant temperature
is not reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure low/ engine coolant temperature high
warning light illuminates, this
may indicate a malfunction.
Move the vehicle off the road in
a safe area and allow the engine
to cool. If after checking the oil
and coolant, the oil pressure
low/engine coolant temperature
