STARTING A GASOLINE ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the
engine. If the engine idle speed does not
slow down, have your vehicle checked as
soon as possible.Note: You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each time,
without the engine starting, you reached the
60-second time limit. A message appears
in the information display alerting you that
you exceeded the cranking time. You
cannot attempt to start the engine for at
least 15 minutes. After 15 minutes, you are
limited to a 15-second engine cranking time.
You need to wait 60 minutes before you can
crank the engine for 60 seconds again.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal floor.
Failure to follow these instructions may
result in fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components. Similar
federal or provincial laws may apply in
Canada. We do not approve of any vehicle
modification without first determining
applicable laws.
Tampering with emissions control
systems including related sensors
or the Diesel Exhaust Fluid system
can result in reduced engine power and the
illumination of the service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by any
person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to the
ultimate purchaser or while it is in use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive exhaust
smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.

If Your Vehicle Gets Stuck
WARNING: Apply the parking brake,
shift into park (P), switch the ignition off
and remove the key before you leave your
vehicle. Failure to follow this instruction
could result in personal injury or death.
WARNING: If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible.
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
could 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.
It could be beneficial to disengage Traction
Control while attempting to rock the vehicle.Note:Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note:Do not rock the vehicle for more than
a few minutes or damage to the transmission
and tires could occur or the engine could
overheat.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid "over-driving"
your vehicle (i.e., turn the steering wheel
only as rapidly and as far as required to
avoid the emergency). Excessive steering
can result in less vehicle control, not
more. Additionally, smooth variations of
the accelerator and/or brake pedal
pressure should be utilized if changes in
vehicle speed are called for. Avoid abruptsteering, acceleration or braking which
could result in an increased risk of loss
of vehicle control, vehicle rollover and/or
personal injury. Use all available road
surface to return the 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 the vehicle goes from one type of
surface to another (i.e., from concrete to
gravel) there is a change in the way the
vehicle responds to a maneuver
(steering, acceleration or braking). Again,
avoid these abrupt inputs.
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 spinning the wheels.

GENERAL INFORMATION
Note: Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn. Have your
vehicle checked. If your vehicle has
continuous vibration or shudder in the
steering wheel when braking, have your
vehicle checked.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. Wet brakes result in reduced
braking efficiency. Gently press the brake
pedal a few times when driving from a car
wash or standing water to dry the brakes.
See Cleaning the Wheels (page 427).
Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move
the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle
checked. If your vehicle has to be towed,
we recommend that you contact a
professional towing service.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
can reduce stopping distances in critical
situations.Note:Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp illuminates momentarily
when you switch the ignition on to
confirm the lamp is functional.
If the warning lamp does not illuminate
during start up, remains on or flashes, the
system may be disabled. Have the system
checked. If the anti-lock brake system is
disabled, normal braking is still operational.
See Warning Lamps and Indicators (page
131).
Note:Indicators vary depending on region.

Brakes
Page 310 of 681

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 307).The system may not correctly operate in any
of the following conditions:
• The lane is too narrow or wide.
• The system does not detect at least one
lane marking or when lanes merge or
split.
• 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.

Trailer Lamps
WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp wiring;
this may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Most towed vehicles require trailer lamps.
Make sure all running lights, brake lights,
direction indicators and hazard flashers are
working.
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
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with 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 is equipped with 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.
• 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 automatic transmission in park
(P).
4. Place wheel chocks in front and back of
the trailer wheels. (Chocks not included
with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note:Disconnect the wiring to the trailer
before backing the trailer into the water.
