Charging System
Light
The charging system light
comes on briefly when the
ignition is turned on, but the
engine is not running, as a
check to show the light is
working. It should go out when
the engine is started.
If the light stays on, or comes
on while driving, there may be
a problem with the electrical
charging system. Have it
checked by your dealer.
Driving while this light is on
could drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a
message.If a short distance must be
driven with the light on, be
sure to turn off all
accessories, such as the radio
and air conditioner. Find a safe
place to stop the vehicle.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the
vehicle’s emission control
on-board diagnostic system.
If this light is on while the
engine is running, a
malfunction has been
detected and the vehicle may
require service. The light
should come on to show that it
is working when the ignition is
in Service Mode. See Ignition
Positions
0247.
Malfunctions are often
indicated by the system
before any problem is
noticeable. Being aware of the
light and seeking service
promptly when it comes on
may prevent damage.
Caution
If the vehicle is driven
continually with this light on,
the emission control system
may not work as well, the
fuel economy may be lower,
and the vehicle may not run
smoothly. This could lead to
costly repairs that might not
be covered by the vehicle
warranty.
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

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 Equipment0325.
See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
.The light is on when the
engine is running.
.The light does not come on
when the ignition is in
Service Mode.
.Critical emission control
systems have not been
completely diagnosed. If this
happens, the vehicle would
not be ready for inspection
and might require
several days of routine
driving before the system is
ready for inspection. This
can happen if the 12-volt battery has recently been
replaced or run down, or if
the vehicle has been
recently serviced.
See your dealer if the vehicle
will not pass or cannot be
made ready for the test.
Brake System

If the light comes on while
driving, pull off the road and
stop carefully. The brake
system has electric brake
boost. Vehicle speed may be
limited when the brake system
warning light comes on. The
brake pedal might be harder to
push, or the brake pedal may
go closer to the floor. It could
take longer to stop. If the light
is still on, have the vehicle
towed for service. See
Transporting a Disabled
Vehicle 0407.

Remote system. It may help to
have another person assist
with the programming
process.1. Hold the end of the hand-held transmitter
about 3 to 8 cm (1 to 3 in)
away from the Universal
Remote system buttons
with the indicator light in
view. The hand-held transmitter was supplied
by the manufacturer of the
garage door opener
receiver.
2. Press and release one of the three Universal
Remote system buttons to
be programmed. Press and
hold the hand-held
transmitter button. Do not
release the hand-held
transmitter button until
the indicator light changes
from a slow to a rapid flash
or continuous light. Then
release the hand-held
transmitter button.
Some garage door
openers may require
substitution of Step 2 with
the procedure under
“Radio Signals for Some
Gate Operators” later in
this section.
3. Press and hold the newly programmed Universal
Remote system button for
five seconds while watching the indicator light
and garage door
activation.
.If the indicator light
stays on continuously or
the garage door moves
when the button is
pressed, then
programming is
complete. There is no
need to complete
Steps 4–6.
.If the indicator light does
not come on or the
garage door does not
move, a second button
press may be required.
For a second time, press
and hold the newly
programmed button for
five seconds. If the
indicator light stays on
continuously or the
garage door moves
when the button is
pressed, then
programming is
complete. There is no
need to complete
Steps 4–6.

Vehicle Positioning
At times, the position of the
vehicle on the map could be
inaccurate due to one or more
of the following reasons:
.The road system has
changed.
.The vehicle is driving on
slippery road surfaces such
as sand, gravel, or snow.
.The vehicle is traveling on
winding roads or long,
straight roads.
.The vehicle is approaching a
tall building or a large
vehicle.
.The surface streets run
parallel to a freeway.
.The vehicle has been
transferred by a vehicle
carrier or a ferry.
.The current position
calibration is set incorrectly.
.The vehicle is traveling at
high speed.
.The vehicle changes
directions more than once,
or the vehicle is turning on a
turn table in a parking lot.
.The vehicle is entering and/
or exiting a parking lot,
garage, or a lot with a roof.
.The GPS signal is not
received.
.A roof carrier is installed on
the vehicle.
.Tire chains are installed on
the vehicle.
.The tires are replaced
or worn.
.The tire pressure for the
tires is incorrect.
.This is the first navigation
use after the map data is
updated.
.The 12-volt battery has been
disconnected for
several days.
.The vehicle is driving in
heavy traffic where driving is
at low speeds, and the
vehicle is stopped and
started repeatedly.
Problems with Route
Guidance
Inappropriate route guidance
can occur under one or more
of the following conditions:
.The turn was not made on
the road indicated.
.Route guidance might not be
available when using
automatic rerouting for the
next right or left turn.
.The route might not be
changed when using
automatic rerouting.
.There is no route guidance
when turning at an

Driving and Operating 241
Warning (Continued)
.Open a window about
5 cm (2 in) on the vehicle
side 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 circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust
0 256.
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the
engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running 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

{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).
For All-Wheel Drive (AWD),
select Off-Road or AWD mode.
See Driver Mode Control
0 269 and
All-Wheel Drive 0263.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in
