USING DRIVER ALERT
Switching the System On and Off
Switch the system on or off using the
information display. See General
Information (page 134).
When active, the system monitors your
alertness level based upon your driving
behavior in relation to the lane markings, and
other factors.
System Warnings
Note: The system does not issue warnings
below approximately
40 mph (64 km/h).
Note: If you receive a warning you should
consider resting, even if the current
assessment is within the typical range.
The warning system has two stages. At first,
the system issues a temporary warning that
you need to take a rest. This message only
appears for a short time. If the system
detects further reduction in driving alertness,
it may issue another warning that remains in
the information display for a longer time. You
can press OK on the steering wheel control
to clear the warning. Resetting the System
You can reset the system by either:
•
Switching the ignition off and on.
• Stopping the vehicle and then opening
and closing the driver’ s door.

CHANGING THE ENGINE AIR
FILTER WARNING: To reduce the risk of
vehicle damage and personal burn injuries,
do not start your engine with the air
cleaner removed and do not remove it
while the engine is running.
When changing the engine air filter, do not
allow debris or foreign material to enter the
air induction system. Engine components
are susceptible to damage not covered by
the vehicle Warranty. Change the air filter element at the correct
interval. See Scheduled Maintenance (page

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%.
• Coolant concentrations below 40%
decrease the freeze 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
450).
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.

To disconnect or remove the battery, do the
following:
1. Apply the parking brake and switch the ignition off.
2. Switch all electrical equipment off, for 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.

Tire Rotation
WARNING: If the tire label shows
different tire pressures for the front
and rear tires and the vehicle has a
tire pressure monitoring system, then
you need to update the settings for
the system sensors. Always perform
the system reset procedure after tire
rotation. If you do not reset the system,
it may not provide a low tire pressure
warning when necessary.
Note: If your tires show uneven wear,
ask an authorized dealer to check for
and correct any wheel misalignment,
tire imbalance or mechanical problem
involved before tire rotation. Note:
Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. A dissimilar spare wheel and
tire assembly is defined as a spare
wheel and tire assembly that is different
in brand, size or appearance from the
road tires and wheels. If you have a
dissimilar spare wheel and tire
assembly, it is intended for temporary
use only and should not be used in a
tire rotation.
Note: After having your tires rotated,
inflation pressure must be checked and
adjusted to the vehicle requirements.
Rotating your tires at the recommended
interval will help your tires wear more
evenly, providing better tire performance
and longer tire life. Sometimes irregular
tire wear can be corrected by rotating
the tires.
See Scheduled Maintenance
(page 568).
Tire Rotation Diagram
Rear-wheel drive and all-wheel drive
vehicles, front tires at left of diagram. USING SUMMER TIRES
Summer tires provide superior performance
on wet and dry roads. Summer tires do not
have the Mud and Snow (M+S or M/S) tire
traction rating on the tire side wall. Since
summer tires do not have the same traction
performance as All-season or Snow tires, we
do not recommend using summer tires when
temperatures drop to approximately 45°F
(7°C) or below (depending on tire wear and
environmental conditions) or in snow and ice
