Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first
2 400 km (1,500 mi) of driving this
vehicle. Parts have a break-in
period and performance will be
better in the long run.
For the first 2 400 km (1,500 mi):
.Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 engine rpm.
. Avoid driving at any one
constant speed, fast or slow.
. Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
. Do not let the engine labor.
Never lug the engine in high
gear at low speeds. .
Do not participate in track
events, sport driving schools,
or similar activities during this
break-in period.
. Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 400 km (1,500 mi).
. To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
300 km (200 mi). New tires do
not have maximum traction and
may tend to slip.
. New brake linings also need a
break–in period. Avoid making
hard stops during the first
300 km (200 mi). This is
recommended every time brake
linings are replaced.
Carbon Fiber
This vehicle may be equipped with
carbon fiber parts. Dealer-installed
accessories may also contain
carbon fiber.
{Warning
The exposed edges of carbon
fiber parts can be sharp when
damaged. You or others could be
injured. Use caution when
washing the vehicle, coming in
contact with damaged carbon
fiber parts, or removing these
parts. See your dealer for
replacement.

Information Center (DIC) will
display a message. SeeKey
and Lock Messages 0139 and
Remote Keyless Entry (RKE)
System Operation 029.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold weather
(below −18 °C or 0 °F), it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you press the ENGINE START/
STOP button, if equipped. Wait
at least 15 seconds between
each try, to allow the cranking motor to cool down. When the
engine starts, release the
accelerator. If the vehicle starts
briefly but then stops again, do
the same thing. This clears the
extra gasoline from the engine.
Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Stop/Start System
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
may be injured. Because the
vehicle has the auto engine stop/
start feature, the vehicle's engine
might seem to be shut off;
however, once the brake pedal is
released, the engine will start up
again.
(Continued)
Warning (Continued)
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.
If equipped with the 2.0L L4, or 3.6L
V6 non-turbo engine, the vehicle
has a fuel saving stop/start system
to shut off the engine to help
conserve fuel.
Auto Engine Stop/Start
When the brakes are applied and
the vehicle is at a complete stop,
the engine may turn off. When
stopped, the tachometer displays
AUTO STOP. See Tachometer
0 116. When the brake pedal is
released or the accelerator pedal
pushed, the engine will restart.
Auto Stop may be deactivated if:
. A minimum vehicle speed is not
reached.
. The engine or transmission is
not at the required operating
temperature.

Fuel Additives
Gasoline should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly.
Some gasoline does not contain
sufficient quantities of additive to
keep fuel injectors and intake valves
clean. To make up for this lack of
detergency, add Fuel System
Treatment PLUS to the fuel tank at
every engine oil change or every
15 000 km (9,000 mi), whichever
occurs first. It is available at your
dealer.
Filling the Tank
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.(Continued)
Warning (Continued)
.To help avoid injuries to you
and others, read and follow
all the instructions on the
fuel pump island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.
. Do not leave the fuel pump
unattended.
. Do not use a cell phone
while refueling.
. Do not reenter the vehicle
while pumping fuel.
. Keep children away from
the fuel pump and never let
children pump fuel.
. Fuel can spray out if the
refueling nozzle is inserted
too quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot
(Continued)
Warning (Continued)
weather. Insert the refueling
nozzle slowly and wait for
any hiss noise to stop prior
to beginning to flow fuel
To open the fuel door, push and
release the rearward center edge of
the door. If equipped, the fuel door
is locked when the vehicle doors are
locked. Press

or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
If the trailer turn signal bulbs burn
out, the arrows on the instrument
cluster will still flash for turns. It is
important to check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gearbefore starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might get hot and no longer
work well.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if
the transmission shifts too often
under heavy loads and/or hilly
conditions.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
0 269.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill. 2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in place, release the regular
brakes until the chocks absorb
the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and store the chocks.

Maintenance when Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See
Maintenance Schedule0329.
Things that are especially important
in trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system, and
brake system. It is a good idea to
inspect these before and during
the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Trailer Towing (Sedan L4
Engine)
A maximum speed of 100km/h must
not be exceeded, even in countries
where higher speed limits are
permitted.
Before pulling a trailer, there are
three important considerations that
have to do with weight:
. The weight of the trailer.
. The weight of the trailer tongue. .
The total weight on your
vehicle's tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
1136 kg (2,500 lb). But even that
can be too heavy.
It depends on how the rig is used.
For example, speed, altitude, road
grades, outside temperature, and
how much the vehicle is used to pull
a trailer are all important. It can
depend on any special equipment
on the vehicle, and the amount of
tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue”
later in this section.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers, and cargo
in the tow vehicle must be
subtracted from the maximum trailer
weight.
Ask your dealer for trailering
information or advice.
Weight of the Trailer Tongue
The tongue load (1) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle.
If there are a lot of options,
equipment, passengers, or cargo in
the vehicle, it will reduce the tongue
weight the vehicle can carry, which
will also reduce the trailer weight the
vehicle can tow. If towing a trailer,
the tongue load must be added to
the GVW because the vehicle will
be carrying that weight, too. See
Vehicle Load Limits 0189.

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0261.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle must be on level ground. The
engine oil dipstick handle is a loop.
See
Engine Compartment Overview
0 252 for the location of the engine
oil dipstick.
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull out the dipstick and wipe it with a clean paper towel or
cloth, then push it back in all
the way. Remove it again,
keeping the tip down, and
check the level.
