Switch the heated steering wheel on and off
using the touchscreen. Touch 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 release, every two seconds,
your hand-held transmitter until the
HomeLink indicator light changes to a
rapidly blinking or continuously on light.
2. Release the hand-held transmitter button.
3. Continue programing HomeLink. See In-Vehicle Programming, Step 4
.
Erasing the Function Button Codes
Note: You cannot erase individual buttons. 1. Press and hold the outer two function
buttons simultaneously for approximately
10 seconds until the indicator light above
the buttons flashes rapidly.
2. When the indicator light flashes, release
the buttons. You erased the codes for all
buttons.
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.

When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn around
because this could cause vehicle roll over.
It is better to reverse back to a safe location.
Apply just enough power to the wheels to
climb the hill. Too much power causes the
tires to slip, spin or lose traction, resulting in
loss of vehicle control. 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. Disengage overdrive
or move the transmission selector lever 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 your vehicle.
If your vehicle has anti-lock brakes, 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
transmission damage.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide when 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. Although a four-wheel
drive vehicle may accelerate better than a
two-wheel drive vehicle in snow and ice, it
does not stop any faster as braking occurs
at all four wheels. Do not become
overconfident in any road condition.
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.
Do not pump the brake pedal. See Hints on
Driving With Anti-Lock Brakes
(page 238).

The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.
Canceling the Set Speed
Press and release the button or tap
the brake pedal.
The set speed does not erase.
Resuming the Set Speed Press and release the button.
Your vehicle speed returns to the previously
set speed and gap setting. The set speed
displays continuously in the information
display when the system is active.
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
Automatic cancellation can also occur when: •
The tires lose traction.
• You apply the parking brake.
Park Brake Application
Automatic parking brake application and
cancellation occurs if:
• You unbuckle the seatbelt and open the
door after you stop the vehicle.
• You hold the vehicle at a stop
continuously for more than three minutes.
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. Switching Adaptive Cruise Control Off Press and release the button when
the system is in standby mode, or
switch the ignition off.
Note: You erase the set speed and gap
setting when you switch the system off.
Detection Issues 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.

STEERING
Electric Power Steering
WARNING: The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked as soon as possible. WARNING:
If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required. If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to the
steering system. You do not lose the ability
to steer your vehicle manually. Typical
steering and driving maneuvers allow the
system to cool and return to normal
operation.
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 may also make the steering
seem to wander or pull.
Adaptive Learning
(If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with the
brake system to help operate advanced
stability control and accident avoidance
systems. Additionally, whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short distance
before the system relearns the strategy and
reactivates all systems.

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 380).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop. •
Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
There are also some things you may want to
avoid doing because they reduce your fuel
economy:
• Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly terrain.

Note:
Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system. See Capacities
and Specifications (page 435). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 435).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways. 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 435).
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.
