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.

Automatic Transmission Adaptive
Learning
This feature may increase durability and
provide consistent shift feel over the life of
your vehicle. A new vehicle or transmission
may have firm shifts, soft shifts or both. This
operation is normal and does not affect
function or durability of the transmission.
Over time, the adaptive learning process fully
updates transmission operation.
If Your Vehicle Gets Stuck in Mud or
Snow
If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute or damage to the transmission and
tires may occur, or the engine may overheat.

It may be safer to stay on the shoulder of the
road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly.
It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than attempt
a sudden return to the road which could
cause your vehicle to slide sideways out of
control or roll over. Remember, your safety
and the safety of others should be your
primary concern.
If Your Vehicle Gets Stuck
WARNING: Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note: Do not rock your vehicle for more than
a minute or damage to the transmission and
tires may occur or the engine could
overheat.
Emergency Maneuvers
In an unavoidable emergency where a
sudden sharp turn must be made, remember
to avoid over-driving your vehicle, for
example, turn the steering wheel only as
rapidly and as far as required to avoid the
emergency. Excessive steering can result in
loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are
required. Avoid abrupt steering, acceleration
and braking. This could result in an increased
risk of vehicle roll over, loss of vehicle control
and personal injury. Use all of the available
road surface to bring your vehicle to a safe
direction of travel. In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of surface
to another such as from concrete to gravel,
there may be a change in the way your
vehicle responds to a maneuver, for
example, steering, acceleration or braking.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid excessive wheel slip.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could become stuck to
the point that assistance may be required
from another vehicle. Remember, you may
be able to back out the way you came if you
proceed with caution.

Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability could be
limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal when slowly moving.
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can lose
traction in slick mud. As when you are driving
over sand, apply the accelerator slowly and
avoid spinning your wheels. If the vehicle
does slide, steer in the direction of the slide
until you regain control of the vehicle.
If the transmission, transfer case or front axle
are submerged in water, their fluids should
be checked and changed, if necessary.
If the front or rear axle is submerged in water,
the axle lubricant should be replaced.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance that could damage
drive components.
Note:
Driving through deep water could
damage the vehicle.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
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.

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.

Before Towing a Trailer
Practice turning, stopping and backing up to
get the feel of your vehicle-trailer
combination before starting on a trip. When
turning, make wider turns so the trailer
wheels clear curbs and other obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled
50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control when carrying
heavy loads or in hilly terrain. The speed
control may turn off automatically when
you are towing on long, steep grades. •
Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission has a Grade Assist
or Tow/Haul feature, use this feature
when towing. This provides engine
braking and helps eliminate excessive
transmission shifting for optimum fuel
economy and transmission cooling.
• If your vehicle has AdvanceTrac with
RSC, this system may turn on during
typical cornering maneuvers with a
heavily loaded trailer. This is normal.
Turning the corner at a slower speed
while towing may reduce this tendency.
• If your vehicle has Adaptive suspension,
you can select NORMAL or SPORT drive
control modes for better experience
when towing a trailer.
See Information
Displays (page 134). •
If you are towing a trailer frequently in
hot weather, hilly conditions, at the gross
combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic gear
lubricant (if the axle is not already filled
with it).
See Capacities and
Specifications (page 438).
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in the front and back
of the trailer wheels.
Note: Chocks are not included with your
vehicle.
