Note:
The controls change when you enter
a submenu.
The following controls are only available
once you enter a submenu: See General Information (page 134).
HEATED STEERING WHEEL
(IF
EQUIPPED)
The heated steering wheel button is on the
climate controls. Press the button to switch the
heated steering wheel on and off.
Note: You can use the heated steering
wheel only when the engine is running. Note:
The system uses a sensor and is
designed to control the temperature of the
steering wheel and to prevent it from
overheating.
Note: In warm temperatures, the steering
wheel quickly reaches its maximum
temperature and the system reduces the
current to the heating element. This could
cause you to think that the system has
stopped working but it has not. This is
normal.

3. Press and hold the function button you
want to program for 2 seconds, then
release. Repeat this step. Depending on
your brand of garage door opener, you
may need to repeat this sequence a third
time.
Gate Operator / Canadian Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit) after
several seconds of transmission – which may
not be long enough for HomeLink to pick up
the signal during programming. Similar to
this Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner. Note:
If programming a garage door opener
or gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.
1. Press and hold the HomeLink button while you press and release, every two
seconds, your hand-held transmitter until
the HomeLink indicator light changes
from a slow to a rapidly blinking light.
2. Release both the HomeLink and hand-held transmitter buttons.
3. Continue programing HomeLink. See In-Vehicle Programming
.
Erasing the Function Button Codes
Note: You cannot erase individual buttons. 1. Press and hold the outer two function
buttons simultaneously for approximately
20 seconds until the indicator lights
above the buttons flash rapidly.
2. When the indicator lights flash, release the buttons. The codes for all buttons are
erased.
Reprogramming a Single Button
To program a device to a previously trained
button, follow these steps:
1. Press and hold the desired button. Do NOT release the button.

Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral; instead, disengage
overdrive or manually shift to a lower gear.
When descending a steep hill, avoid sudden
hard braking as you could lose control. The
front wheels have to be turning in order to
steer the vehicle.
Your vehicle has anti-lock brakes, therefore
apply the brakes steadily. Do not “pump
” the
brakes.
Driving on Snow and Ice WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle. Note:
Excessive tire slippage can cause
driveline damage.
AWD vehicles have advantages over 2WD
vehicles in snow and ice but can skid like
any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and ice.
Apply the accelerator slowly and steadily
when starting from a full stop.
Avoid sudden braking as well. Although an
AWD vehicle could accelerate better than a
two-wheel drive vehicle in snow and ice, it
will not stop any faster, because as in other
vehicles, braking occurs at all four wheels.
Do not become overconfident as to road
conditions. Make sure you allow sufficient distance
between you and other vehicles for stopping.
Drive slower than usual and consider using
one of the lower gears. In emergency
stopping situations, apply the brake steadily.
Since your vehicle is equipped with a four
wheel (ABS), do not “pump
” the brakes. See
Hints on Driving With Anti-Lock Brakes
(page
258).
Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and tested
to provide predictable performance whether
loaded or empty and durable load carrying
capability. For this reason, we strongly
recommend that you do not make
modifications such as adding or removing
parts (such as lowering kits or stabilizer bars)
or by using replacement parts not equivalent
to the original factory equipment.

(If Equipped)

Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle
’s regular brake system to prevent it
from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
ADAPTIVE CRUISE CONTROL
LIMITATIONS - VEHICLES WITH:
ADAPTIVE CRUISE CONTROL
WITH LANE CENTERING
Adaptive cruise control limitations apply to
lane centering unless stated otherwise or
contradicted by a lane centering limitation.
See Adaptive Cruise Control Limitations
(page 293). The system may not correctly operate in any
of the following conditions:
•
Your vehicle is not centered in the lane.
• The lane is too narrow or wide.
• The system does not detect at least one
lane marking or when lanes merge or
split.
• You switch the direction indicator on.
• Limited steering torque input is applied.
• Areas under construction or new
infrastructure.
• When modifications to the steering
system have been made.
• When using a spare tire.
Note: The driving assistance torque is limited
and may not be sufficient for all driving
situations such as driving through tight
curves or driving through curves at high
speeds.
Note: In exceptional conditions, the system
may deviate from the center line. ADAPTIVE CRUISE CONTROL
LIMITATIONS - VEHICLES WITH:
ADAPTIVE CRUISE CONTROL
WITH STOP AND GO
Sensor Limitations
WARNING:
On rare occasions,
detection issues can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible. WARNING: Large contrasts in outside
lighting can limit sensor performance.

Extreme continuous steering could increase
the effort you need to steer your vehicle. This
increased effort prevents overheating and
permanent damage to the steering system.
You do not lose the ability to manually steer
your vehicle. Typical steering and driving
maneuvers allow the system to cool and
operate as normal.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds could also make the steering
seem to wander or pull. Adaptive Learning
The electronic power steering system
adaptive learning improves overall handling
and steering on roads with irregularities. It
communicates with the brake system to help
operate advanced stability control and
accident avoidance systems. When you
install a new battery or disconnect the
battery, you need to drive your vehicle a
short distance so it can relearn and reactivate
all systems.
PRE-COLLISION ASSIST
WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury. WARNING:
The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See Gauges (page
126).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually. 1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 390).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the conditions
you drive under, and how you maintain your
vehicle.
You may improve your fuel economy by
keeping these things in mind:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without stopping.
• Anticipate stops; slowing down may
eliminate the need to stop. •
Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling at
55 mph [88 km/h] uses 15% less fuel than
traveling at 65 mph [105 km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold mornings.
• Use the air conditioner or front defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.

Note:
Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Capacities and
Specifications (page 450).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap. Turn the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level. If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze. Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Note:
Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
