Replacing LATCH System
Parts After a Crash
{Warning
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint, resulting
in serious injury or even death in a
crash. To help make sure the
LATCH system is working properly
after a crash, see your dealer to
have the system inspected and any
necessary replacements made as
soon as possible. If the vehicle has the LATCH system
and it was being used during a crash,
new LATCH system parts may be
needed.
New parts and repairs may be
necessary even if the LATCH system
was not being used at the time of the
crash.
Securing Child Restraints
(With the Seat Belt in the
Rear Seat)
When securing a child restraint with
the seat belts in a rear seat position,
study the instructions that came with
the child restraint to make sure it is
compatible with this vehicle.
If the child restraint has the LATCH
system, see
Lower Anchors and Tethers
for Children (LATCH System) 072 for
how and where to install the child
restraint using LATCH. If a child
restraint is secured in the vehicle
using a seat belt and it uses a top
tether, see Lower Anchors and Tethers
for Children (LATCH System) 072 for
top tether anchor locations. Do not secure a child seat in a
position without a top tether anchor if
a national or local law requires that
the top tether be anchored, or if the
instructions that come with the child
restraint say that the top tether must
be anchored.
In Canada, the law requires that
forward-facing child restraints have a
top tether, and that the tether be
attached.
If the child restraint or vehicle seat
position does not have the LATCH
system, you will be using the seat belt
to secure the child restraint. Be sure
to follow the instructions that came
with the child restraint.
If more than one child restraint needs
to be installed in the rear seat, be sure
to read
Where to Put the Restraint 071.
1. Put the child restraint on the seat. If the head restraint interferes with
the proper installation of the child
restraint, the head restraint may be
removed. See "Head Restraint
Removal and Reinstallation" under
Lower Anchors and Tethers for
Children (LATCH System) 072.

f:Pull the windshield wiper lever
toward you to spray windshield
washer fluid and activate the wipers.
The wipers will continue until the
lever is released or the maximum
wash time is reached. When the
windshield wiper lever is released,
additional wipes may occur depending
on how long the windshield washer
has been activated. See Washer Fluid
0 295 for information on filling the
windshield washer fluid reservoir.
{Warning
In freezing weather, do not use the
washer until the windshield is
warmed. Otherwise the washer fluid
can form ice on the windshield,
blocking your vision.
{Warning
Before driving the vehicle, always
clear snow and ice from the hood,
windshield, roof, and rear of the
vehicle, including all lamps and

Warning (Continued)
windows. Reduced visibility from
snow and ice buildup could lead to
a crash.
Clear snow and ice from the wiper
blades and windshield before using
them. If frozen to the windshield,
carefully loosen or thaw them.
Damaged blades should be replaced.
See Wiper Blade Replacement 0299.
Heavy snow or ice can overload the
wiper motor. See Electrical System
Overload 0302.
Wiper Parking
If the ignition is turned off while the
wipers are on LO, HI, or AUTO with
Rainsense turned off, they will
immediately stop.
If the windshield wiper lever is then
moved to OFF before the driver door is
opened or within 10 minutes, the
wipers will restart and move to the
base of the windshield. If the ignition is turned off while the
wipers are performing wipes due to
windshield washing or Rainsense, the
wipers continue to run until they
reach the base of the windshield.
Rainsense
If equipped with Rainsense and the
feature is turned on, a sensor near the
top center of the windshield detects
the amount of water on the
windshield and controls the frequency
of the windshield wiper based on the
current sensitivity setting.
Keep this area of the windshield clear
of debris to allow for best system
performance.
AUTO :
Move the windshield wiper
lever to AUTO. Turn the band on the
wiper lever to adjust the sensitivity.

Warning Lights, Gauges,
and Indicators
Warning lights and gauges can signal
that something is wrong before it
becomes serious enough to cause an
expensive repair or replacement.
Paying attention to the warning lights
and gauges could prevent injury.
Some warning lights come on briefly
when the engine is started to indicate
they are working. When one of the
warning lights comes on and stays on
while driving, or when one of the
gauges shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.

Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0283.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
.If fuel has been added to the vehicle
using the capless fuel funnel
adapter, make sure that it has been
removed. See “Filling the Tank with
a Portable Gas Can ”under Filling the
Tank 0268. The diagnostic system
can detect if the adapter has been
left installed in the vehicle, allowing
fuel to evaporate into the
atmosphere. A few driving trips with
the adapter removed may turn off
the light.
.Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up.
If this occurs, change the fuel brand. It may require at least one
full tank of the proper fuel to turn
the light off. See
Recommended Fuel
0 267.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0280.
See your dealer if assistance is needed.
