DRIVING
DRIVING
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.
Your vehicle is not designed to tow a trailer. Attempting to do so can void your
vehicle warranties.
The maximum load for your vehicle is 850 lbs (385 kg). See the Tire and Loading
Information label on the driver’s doorjamb.
Label Example
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 r
esulting 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 y
our 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.
Learn about preparation for driving, as well as other features.
Before Driving
Check the following items before you begin driving.
Exterior Checks
•
Mak
e sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
•

R
emove any frost, snow, or ice.
•

Mak
e 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.
•

Mak
e sure the tires are in good condition.
•

Mak
e 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•
Stor
e or secure all items on board properly.
•

Do not pile items higher
than the seat height.
•

Do not place an
ything in the front seat footwells. Secure the floor mats.
•

If
you have any animals on board, do not let them move freely in the vehicle.
•

Secur
ely close and lock all doors and the trunk.
•

A
djust your seating position, mirrors, and steering wheel properly.
•

Mak
e sure items placed on the floor behind the front seats cannot roll under
the seats.
•

Ev
eryone 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.
In addition:
•

During
the first 600 miles (1,000 km) of operation, avoid sudden acceleration
or full throttle operation so as to not damage the engine or powertrain.
•

A
void hard braking for the first 200 miles (300 km). You should also follow this
when the brake pads are replaced.

102 || 103
HANDLING THE UNEXPECTED
HANDLING THE UNEXPECTED
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:
•

Pr
ess and hold the ENGINE START/STOP button for
two seconds, or
•

Firml
y press the ENGINE START/STOP button two
times.
The steering wheel will not lock. The power mode changes to ACCESSORY, unless
the shift lever is in Park, 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.
Do not press the button while driving unless it is absolutely necessary for the
engine to be switched off.
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.
NOTICE
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
Overheating
Signs your engine is overheating: •
The
temperature gauge needle is at the H mark
•

The engine suddenl
y loses power
•

Steam
or spray comes out from under the hood
•

The message
Engine Temperature Too Hot appears on the display.
1.

Immediatel
y park the vehicle in a safe place. Turn
off all accessories and turn on the hazard warning
lights.
2.

If no steam
or spray is present: Keep the
engine running and open the hood (see page
118).
If steam or spray is present: Turn off the engine
and wait until it subsides. Then, open the hood
(see page 118).
3.

Check that the
cooling fan is operating and stop the engine once the
temperature gauge needle goes down. If the cooling fan is not operating,
immediately stop the engine.

4.


Once
the engine has cooled down, inspect the coolant level and check the
cooling system components for leaks. If the coolant level in the reserve tank
is low, add coolant until it reaches the MAX mark. If there is no coolant in the
reserve tank, make sure the radiator is cool, then cover the radiator cap with a
heavy cloth and open the cap. If necessary, add coolant up to the base of the
filler neck, and put the cap back on.
Once the engine has cooled sufficiently, restart it and check the temperature
gauge. If the temperature needle has gone down, resume driving. If it has not gone
down, contact a dealer for repairs.
Reserve tank MAX
MIN
Steam and spray from an overheated engine can seriously scald you.
Do not open the hood if steam is coming out.
WARNING
Removing the radiator cap while the engine is hot can cause the coolant to
spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the radiator
cap.
WARNING
Continuing to drive with the temperature gauge needle at the H mark may
damage the engine.

Testing of Readiness Codes
Your vehicle has readiness codes as part of the onboard self-diagnostic system.
Some states use these codes for testing to verify whether your vehicle’s emissions
components are working properly. The codes may not be read if you go through the
testing just after the battery has gone dead or been disconnected.
To check if they are set, set the power mode to ON without starting the engine.
The malfunction indicator lamp will come on for several seconds. If it goes off, the
readiness codes are set. If it blinks five times, the readiness codes are not set.
If you are required to have your vehicle tested before the readiness codes are set,
prepare the vehicle for retesting by doing the following:
1.

Fill the
gas tank to approximately 3/4 full.
2.

P
ark the vehicle and leave the engine off for 6 hours or more.
3.

Mak
e sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4.

Start
the engine without touching the accelerator pedal, and let it idle for 20
seconds.
5.

K
eep the vehicle in Park. Increase the engine speed to 2,000 rpm, and hold it
there for about 3 minutes.
6.

Let
the engine idle with your foot off the accelerator for 20 seconds.
7.
Select a nearb

y, lightly traveled major highway where you can maintain a speed
of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway
with the vehicle in Drive. Do not use cruise control. When traffic allows, drive
for 90 seconds without using the accelerator pedal. (Vehicle speed may vary
slightly; this is OK.) If you cannot do this for a continuous 90 seconds because of
traffic conditions, drive for at least 30 seconds, then repeat two more times (for
a total of 90 seconds).
8.
