locks to prevent passengers from
opening the rear doors from the
inside.
Open the rear doors to access the
security locks on the inside edge
of each door.To set the locks, insert a key into
the slot and turn it to the horizontal
position. The door can only be
opened from the outside with the
door unlocked. To return the door to
normal operation, turn the slot to
the vertical position.
Liftgate
{CAUTION
It can be dangerous to drive
with the liftgate open because
carbon monoxide (CO) gas can
come into your vehicle. You
cannot see or smell CO. It can
cause unconsciousness and
even death.
(Continued)
CAUTION (Continued)
If you must drive with the liftgate
open, or if electrical wiring or
other cable connections must
pass through the seal between
the body and the liftgate:
Make sure all other windows
are shut.
Turn the fan on your heating
or cooling system to its
highest speed with the
recirculation mode off. That
will force outside air into your
vehicle. See Climate Control
System in the index.
If you have air outlets on or
under the instrument panel,
open them all the way.

Automatic Transmission
Fluid
It is not necessary to check
the transmission uid level.
A transmission uid leak is the only
reason for uid loss. If a leak
occurs, take your vehicle to the
dealer/retailer service department
and have it repaired as soon
as possible.
Change the uid and lter at the
intervals listed in the Maintenance
Schedule. See “Additional
Required Services” in Service
and Maintenance. Be sure to use
the transmission uid listed in
“Recommended Fluids and
Lubricants” in Service and
Maintenance.
Notice:Use of the incorrect
automatic transmission uid
may damage your vehicle,
and the damages may not becovered by your warranty.
See “Recommended Fluids
and Lubricants” in the Limited
Warranty, Maintenance and Owner
Assistance Information manual.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission uid level.
A transmission uid leak is the only
reason for uid loss. If a leak
occurs, take the vehicle to the
dealer/retailer service department
and have it repaired as soon
as possible. You may also have
your uid level checked by
your dealer/retailer when you have
your oil changed. See “Part D:
Recommended Fluids and
Lubricants” in Service and
Maintenance for the proper uid
to use.
Hydraulic Clutch
The hydraulic clutch linkage in
your vehicle is self-adjusting.
This system does not have its own
reservoir. It receives uid from
the brake master cylinder reservoir.
SeeBrakes on page 9-22for more
information.
Engine Coolant
The cooling system in your vehicle
is lled with DEX-COOL®engine
coolant. This coolant is designed to
remain in your vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst, if you add
only DEX-COOL
®extended life
coolant.
The following explains your cooling
system and how to add coolant
when it is low. If you have a problem
with engine overheating, see
Engine Overheating on page 9-15.

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.

{CAUTION
An electric engine cooling fan
under the hood can start up
even when the engine is not
running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
If the coolant inside the coolant
reservoir is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be at or
above the KALT/COLD mark on the
coolant reservoir. If it is not, you
may have a leak at the coolant
reservoir pressure cap or in
the radiator hoses, heater hoses,
radiator, water pump, or somewhere
else in the cooling system.
{CAUTION
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
re, and you could be burned.
Get any leak xed before you
drive the vehicle.
If there seems to be no leak,
with the engine on, check to see
if the electric engine cooling fans are
running. If the engine is overheating,
both fans should be running.
If they are not, your vehicle needs
service.Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:Using coolant other
than DEX-COOL
®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner, at 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered
by the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.

PassengerTires
Your new vehicle comes with
high-quality tires made by
a leading tire manufacturer.
If you ever have questions about
the tire warranty and where to
obtain service, see the “Limited
Warranty, Maintenance and
Owner Assistance Information”
manual for details.
{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your tires can
cause overheating as a
result of too much exing.
You could have an air-out
and a serious accident.
SeeLoading the Vehicle
on page 8-30.
(Continued)
CAUTION (Continued)
Underinated tires pose
the same danger as
overloaded tires.
The resulting accident
could cause serious
injury. Check all tires
frequently to maintain the
recommended pressure.
Tire pressure should be
checked when your tires
are cold. SeeInflation - Tire
Pressure on page 9-46.
Overinated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
you hit a pothole. Keep
tires at the recommended
pressure.
