•When towing more than 3,500 lbs (1,590 kg), use of gasoline with a pump
octane number of 91 or higher is recommended.
u Towing performance can be affected by high altitude, high temperature, or
steep uphill.
• Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the trailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the trailer tires, including the spare.
• Drive slower than normal.
• Obey posted speed limits for vehicles with trailers.

1Driving Safely with a Trailer
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.1Towing Speeds and Gears
When towing a fixed-sided trailer (e.g., camper), do
not exceed 55 mph (88 km/h).
At higher speeds, the trailer ma y sway or affect
vehicle handling.

Driving
• Monitor your temperature gauge. If it nears the red (Hot) mark, turn off the
climate control system and reduce speed. Pull to the side of the road safely to cool
down the engine if necessary.
• Shift to the
(S
position if the transmission shifts frequently.
If the vehicle tires slip when retrieving a boat from the water, keep the transmission
in
(D
and do not use the sequential shift mode in
(S
. This prevents damage to the
transmission.
Towing Your VehicleYour vehicle is not designed to be towed behind a motor home. If your vehicle needs
to be towed in an emergency, refer to the emergency towing information.2 Emergency Towing P. 480■

Off-Highway Driving GuidelinesGeneral InformationYour vehicle has been designed primarily for use on pavement, however, its higher
ground clearance allows you to occasionally travel on unpaved roads. It is not
designed for trail-blazing, or other challenging off-road activities.
If you decide to drive on unpaved roads, you will find that it requires somewhat
different driving skills and that your vehicle will handle somewhat differently than it
does on pavement. Pay attention to the precautions and tips in this section, and get
acquainted with your vehicle before leaving the pavement.Important Safety PrecautionsTo avoid loss of control or rollover, be sure to follow all precautions and
recommendations:
•Be sure to store cargo properly and do not exceed your cargo load limits.
2Maximum Load Limit P. 309
•Whenever you drive, make sure you and your passengers always wear seat belts.
• Keep your speed low, and never go faster than the conditions allow.
• It’s up to you to continually assess the situation and drive within the limits.
1Off-Highway Driving Guidelines
Failure to operate your vehicle correctly might result
in a crash or a rollover.

2 Precautions While Driving P. 329
Spinning the tires can also damage the SH-AWD
system.

WARNING
Improperly operating this vehicle on or off
pavement can cause a crash or rollover in
which you and your passengers can be
seriously injured or killed.
• Follow all instructions and guidelines in
this owner’s manual.
• Keep your speed low, and don’t drive
faster than conditions permit.

323
uuOff-Highway Driving Guidelines uAvoiding Trouble
Driving
Avoiding Trouble• Check Out Your Vehicle before you leave the pavement and make sure that all
scheduled maintenance has been completed. Pay special attention to the
condition of the tires, and check the tire pressures.
• Remember the route you choose presents limits (too steep or bumpy), you have
limits (driving skill and comfort), and your vehicle has limits (traction, stability, and
power). Failing to recognize these limits will likely put you and your passengers in
a hazardous situation.
• Accelerating and Braking should be done slowly and gradually. Trying to start
or stop too fast can cause a loss of traction and you could lose control.
• Avoiding Obstacles and Debris in the road reduces the likelihood of a rollover
or damage to your suspension or other components.
• Driving on Slopes increases your risk of a rollover, particularly if you attempt to
drive across a slope that is too steep. Going straight up or down a slope is usually
the safest. If you can’t clearly see all conditions or obstacles on a slope, walk it
before you drive it. If there is any doubt whether you can safely pass, don’t try it.
Find another route. If you get stuck when climbing, do not try to turn around.
Back down slowly following the same route you took up the hill.
• Crossing a Stream - Avoid driving through deep water. If you encounter water
in your route (a small stream or large puddle, for example), evaluate it carefully
before going ahead. Make sure it is shallow, flowing slowly, and has firm ground
underneath. If you are not sure of the depth or the ground, turn around and find
another route. Driving through deep water can also damage your vehicle. The
water can get into the transmission and differential, diluting the lubricant and
causing an eventual failure. It can also wash the grease out of the wheel bearings.
• If You Get Stuck , carefully go in the direction that you think will get you
unstuck. Do not spin the tires as this will only make things worse and could
damage the transmission. If you are un able to free yourself, your vehicle will need
to be towed. Front and rear tow hooks are provided for this purpose.

1 Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate control
system, and rear defogger in order to reduce battery drain.If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Bring the keyless access remote close to the ENGINE
START/STOP button if the battery in the keyless
access remote is weak. 2 If the Keyless Access Remote Battery is
Weak P. 463
The engine may not start if the keyless access remote
is subjected to strong radio waves.
Do not hold the ENGINE START/STOP button to
start the engine.
If the engine does not start, wait at least 10 seconds
before trying again.
