Learn about preparation for driving and other features.
Before Driving
Check the following items before you begin driving.
Exterior Checks
•  Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
•  Remove any frost, snow, or ice.
•  Make sure the hood is securely closed.
•  Heat  from the engine and exhaust can ignite  flammable materials left under 
the hood, causing a fire. If you’ve parked your vehicle for an extended period,
inspect and remove any debris that may have collected, such as dried grass
and leaves that have fallen or have been carried in for use as a nest by a small
animal.  Also check under  the hood for leftover  flammable materials after  you 
or someone else has performed maintenance on your vehicle.
•  Make sure the tires are in good condition.
•  Make sure there are no people or objects behind or around the vehicle.
DRIVING
If the doors are frozen shut, use warm water around the door edges to melt any
ice. Do not try to force them open, as this can damage the rubber trim around the
doors. When done, wipe dry to avoid further freezing.
NOTICE
Interior Checks
•  Store or secure all items on board properly.
•  Do not pile items higher than the seat height.
•  Do not place anything in  the front seat  footwells. Make sure  to secure the floor 
mats.
•  If you have any animals on board, do not let them move freely in the vehicle.
•  Securely close and lock all doors and the tailgate.
•  Adjust your seating position, mirrors, and steering wheel properly.
•  Be sure items placed  on the  floor behind  the front seats cannot roll under  the 
seats.
•  Everyone in the vehicle must fasten their seat belt.
Make sure that the indicators in the instrument panel come on when you start the
vehicle, and go off soon after.
Driving Guidelines for Your Utility Vehicle
Utility vehicles have a significantly higher rollover rate than other types of
vehicles. To prevent rollovers or loss of control:
•  Take corners at slower speeds than you would with a passenger vehicle.
•  Avoid sharp turns and abrupt maneuvers whenever possible.
•  Do not modify your vehicle in any way that raises its center of gravity.
•  Never carry more than 165 lbs (75 kg) of cargo on the roof rack (Acura
accessory).
In addition:
•  During the first 600 miles (1,000 km) of operation, avoid sudden acceleration
or full throttle operation so as not to damage the engine or powertrain.
•  Avoid hard braking for the first 200 miles (300 km). You should also follow this
when the brake pads are replaced.
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 guide.
Keep your speed low, and don’t drive faster than conditions permit.
WARNING
Improper accessories or modifications can affect your vehicle’s handling,
stability, and performance, and cause a crash in which you can be seriously hurt
or killed.
Follow all instructions in the vehicle owner’s manual regarding accessories and
modifications.

This figure includes the total weight of all occupants, cargo, and
accessories, and the tongue load if you are towing a trailer. Below are the
steps for determining the correct load limit:
1. Locate the statement “The combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg
or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage
load capacity. For example, if the “XXX” amount equals 1,400 lbs. and
there will be five 150 lb. passengers in your vehicle, the amount of
available cargo and luggage load capacity is 650 lbs. (1,400 - 750 (5 x
150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on
the vehicle. That weight may not safely exceed the available cargo and
luggage load capacity calculated in step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult the Owner’s Manual to determine
how this reduces the available cargo and luggage load capacity of your
vehicle.
Maximum Load Limit
Carrying too much cargo or improperly storing it can affect your vehicle’s handling,
stability, stopping distance, and tires, and make it unsafe.
The maximum load for your vehicle is 870 lbs (395 kg). See the Tire and Loading
Information label on the driver’s doorjamb.

Overloading or improper loading can affect handling and stability and cause a
crash in which you can be hurt or killed.
Follow all load limits and other loading guidelines in this guide.
WARNING
The headlight aim on your vehicle was set by the factory, and does not need to be
adjusted. However, if you regularly carry heavy items in the cargo area or pull a
trailer, have the aiming readjusted at your dealer or by a qualified technician.
In addition, the total weight of the vehicle, all occupants, accessories,
cargo, and trailer tongue load must not exceed the Gross Vehicle Weight
Rating (GVWR) or the Gross Axle Weight Rating (GAWR). Both are on a
label on the driver’s doorjamb.

Emergency Engine Stop
The ENGINE START/STOP button may be used to stop the engine due to an
emergency situation even while driving. If you must stop the engine, choose one of
the following operations:
•  Press and hold the ENGINE START/STOP
button for three seconds, OR
•  Firmly press the ENGINE START/STOP button
three times.
The steering wheel will not lock. The power mode changes to ACCESSORY, unless
the shift lever is in Park (P), in which case the power mode changes to VEHICLE OFF.
Because turning off the engine also disables the power assist the engine provides to
the steering and braking systems, it will require significantly more physical effort
and time to steer and slow the vehicle. Downshift gears and use both feet on the
brake pedal, if necessary, to slow the vehicle and stop immediately in a safe place.
Trying to lift or tow your vehicle by the bumpers will cause serious damage. The
bumpers are not designed to support the vehicle’s weight.
Improper towing such as towing behind a motorhome or other motor vehicle can
damage the transmission.
NOTICE

Emergency Towing
Call a professional towing service if you need to tow your vehicle.
All models
Flat bed equipment: The operator loads your vehicle on the back of a truck. This is
the best way to transport your vehicle.
2WD models
Wheel lift equipment: The tow truck uses two pivoting arms that go under the front
tires and lift them off the ground. The rear tires remain on the ground. This is an
acceptable way to tow your vehicle. Do not press the button while driving unless it is absolutely necessary for the
engine to be switched off.
Tire Pressure Monitoring System (TPMS)
Monitors the tire pressure while you are driving.
If your vehicle’s tire pressure becomes significantly low, the low tire pressure
indicator comes on and a message appears on the multi-information display.
What to Do
Stop your vehicle in a safe place. Adjust the tire pressure to the specified level on
a label on the driver’s doorjamb.
Driving  on an extremely underinflated  tire can cause it to overheat.  An overheated

Tire Information
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition  with adequate tread, and properly inflated.
Inflation Guidelines
•  Properly inflated  tires provide the best combination  of handling, tread life, and 
comfort. Refer to the driver’s doorjamb label or the specifications (see page
120) for the specified pressure.
•  Underinflated  tires wear unevenly, adversely affect handling and  fuel economy, 
and are more likely to fail from overheating.
•  Overinflated  tires make your vehicle ride harshly, are more prone  to road 
hazards, and wear unevenly.
•  Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
•  Measure the air pressure when tires are cold. This means the vehicle has been
parked for at least 3 hours, or driven less than 1 mile (1.6 km). If necessary, add
or release air until the specified pressure is reached. If checked when hot, tire
pressure can be as much as 4-6 psi (30-40 kPa, 0.3-0.5 kgf/cm
2) higher than
checked when cold.
•  At least once a month or before long trips, use a gauge to measure the pressure
in all tires, including the spare. Even tires in good condition can lose 1-2 psi
(10-20 kPa, 0.1-0.2 kgf/cm
2) per month.
Inspection Guidelines
Every  time you inflate  the tires, check  for the  following:
•  Any damage to tires, including bumps, bulges, cuts, splits, or cracks in the side
or tread. Remove any foreign objects and inspect for air leaks. Replace tires if
you see fabric or cord.
•  Uneven or excessive tread wear. Have a dealer check the wheel alignment.
•  Cracks or other damage around the valve stems.
Wear Indicators
The groove where the wear indicator is located is
1/16 inch (1.6 mm) shallower than elsewhere on the
tire. If the tread has worn so low that the indicator
is exposed, replace the tire. Worn out tires have
poor traction on wet roads.
Example of a wear
indicator mark
Tire and Loading Information Label
The label attached to the driver’s doorjamb provides necessary tire and
loading information. Using 
tires that are excessively  worn or improperly inflated can cause 
a crash in which you can be seriously hurt or killed.
Follow all instructions in  this owner’s manual regarding  tire inflation 
and maintenance.

Tire and Wheel Replacement
Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using
tires of a different size or construction can cause certain vehicle systems to
work incorrectly. It is best to replace all four tires at the same time. If that isn’t
possible, replace the front or rear tires in pairs.
If you change or replace a wheel, make sure that the wheel’s specifications match
those of the original wheels. Only use TPMS-specified wheels approved for your
vehicle.
Installing improper tires on your vehicle can affect handling and stability.
This can cause a crash in which you can be seriously hurt or killed.
Always use the size and type of tires recommended in the owner’s manual.

Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road
conditions,  vehicle loading, inflation pressure, maintenance history, speed, and 
environmental conditions (even when the tires are not in use).
In addition  to regular inspections and inflation pressure maintenance, it is 
recommended that you have annual inspections performed once the tires reach
five years old. All tires, including the spare, should be removed from service after
10 years from the date of manufacture, regardless of their condition or state of
wear.
Winter Tires
If driving on snowy or frozen roads, mount all season tires marked “M+S”, snow
tires, or tire chains; reduce speed; and maintain sufficient distance between
vehicles when driving. For winter tires, select the size and load ranges that are
the same as the original tires, and mount them to all four wheels. For tire chains,
install them on the front tires only.
Using the wrong chains, or not properly installing chains, can damage the
brake lines and cause a crash in which you can be seriously injured or killed.
Follow all instructions in this guide regarding the selection and use of tire
chains.
WARNING
Traction devices that are the wrong size or improperly installed can damage your
vehicle’s brake lines, suspension, body, and wheels. Stop driving if they are hitting
any part of the vehicle.
NOTICE
Tire Labeling
The tires that came on your vehicle have a number of markings. Those you
should be aware of are described below.
Glossary of Tire Terminology
Cold Tire Pressure – The tire air pressure when the vehicle has been
parked for at least three hours or driven less than 1 mile (1.6 km).
Load Rating – The maximum load that a tire is rated to carry for a given
inflation pressure.
Maximum Inflation Pressure –  The maximum tire air pressure  that the tire 
can hold.
Maximum Load Rating – The load rating for a tire at the maximum
permissible inflation pressure  for that  tire.
Recommended Inflation Pressure –  The cold tire inflation pressure 
recommended by the manufacturer.
Treadwear Indicators (TWI) – The projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread.
Tire Identification Number (TIN)
The tire identification number (TIN)
is a group of numbers and letters
that look like the example below. TIN
is located on the sidewall of the tire.
DO T B97R FW6X 2209DOT: This indicates that the tire meets all requirements of the U.S. Department of
Transportation.

DOT Tire Quality Grading
The tires on your vehicle meet all U.S. Federal Safety Requirements. All tires are
also graded for treadwear, traction, and temperature performance according to
Department of Transportation (DOT) standards. The following explains these
gradings.
Uniform Tire Quality Grading
Quality grades can be found where applicable on the tire sidewall between tread
shoulder and maximum section width.
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform to Federal Safety Requirements in addition
to these grades.
TreadwearThe treadwear grade is a comparative rating based on the wear rate of the tire
when tested under controlled conditions on a specified government test course.
For example, a tire graded 150 would wear one and one-half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of
tires depends upon the actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving habits, service practices,
and differences in road characteristics and climate.
TractionThe traction grades, from highest to lowest, are AA, A, B, and C. Those grades
represent the tire’s ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
WARNING: The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration, cornering, hydroplaning,
or peak traction characteristics.
TemperatureThe temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and
A represent higher levels of performance on the laboratory test wheel than the
minimum required by law.
WARNING: The temperature grade for this tire is established for a tire that
is properly inflated and not  overloaded. Excessive speed, underinflation,  or 
excessive loading, either separately or in combination, can cause heat buildup
and possible tire failure.
