Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection.
• Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• A coolant concentration of 40%
provides improved overheat protection.
• Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the
coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 335). Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain

example lights and radio.
3. Wait a minimum of two minutes before
disconnecting the battery.
Note: The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty.
4. Disconnect the negative battery cable terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery. 8. To install, reverse the removal
procedure.
Note: Before reconnecting the battery,
make sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Power
Windows (page 86).
• Clock Settings.
• Pre-set radio stations.
Battery Disposal Make sure that you dispose of
old batteries in an
environmentally friendly way.
Seek advice from your local authority
about recycling old batteries.

DIGITAL RADIO (IF EQUIPPED)
Note: HD Radio broadcasts are not
available in all markets.
HD Radio technology is the digital
evolution of analog AM/FM radio. Your
system has a special receiver that allows
it to receive digital broadcasts, where
available, in addition to the analog
broadcasts, it already receives. Digital
broadcasts provide a better sound quality than analog broadcasts with free,
crystal-clear audio and no static or
distortion. For more information, and a
guide to available stations and
programming, please visit
www.hdradio.com.
When HD Radio is on and you tune to a
station broadcasting HD Radio technology,
you may notice the HD Radio logo on your
screen. When this logo is available, you
may also see Title and Artist fields
on-screen.
The multicast indicator appears in FM
mode, only, if the current station is
broadcasting multiple digital broadcasts.
The highlighted numbers signify available
digital channels where new or different
content is available. HD1 signifies the main
programming status and is available in
analog and digital broadcasts. Other
multicast stations, HD2 through HD7, are
only available digitally.
When HD Radio broadcasts are active, you
can access the following functions:
•
Memory presets allow you to save an
active channel as a memory preset.
Touch and hold a memory preset slot
until the sound returns. There is a brief
mute while the radio saves the station.
Sound returns when finished. When
switching to an HD2 or HD3 memory
preset, the sound mutes before the
digital audio plays, because the system
has to reacquire the digital signal.
Note: As with any saved radio station, you
cannot access the saved station if your
vehicle is outside the station ’s reception
area.
