Starting and Operating
New Vehicle Break-In
Caution
The vehicle does not need an
elaborate break-in. But it will
perform better in the long run if
you follow these guidelines:
.Do not drive at any one constant
speed, fast or slow, for the first
800 km (500 mi). Do not make
full-throttle starts. Avoid
downshifting to brake or slow the
vehicle.
.Avoid making hard stops for the
first 300 km (200 mi) or so.
During this time the new brake
linings are not yet broken in.
Hard stops with new linings can
mean premature wear and earlier
replacement. Follow this
breaking-in guideline every time
you get new brake linings.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
If the pushbutton start is not working,
the vehicle may be near a strong radio
antenna signal causing interference to
the Remote Keyless Entry (RKE)
system. See Remote Keyless Entry
(RKE) System Operation 07.
To shift out of P (Park), the vehicle
must be turned on and the brake
pedal must be applied. Stopping the Engine/OFF (No
Indicator Light) :
When the vehicle is
stopped, press ENGINE START/STOP
once to turn the engine off.

active. See Retained Accessory Power
(RAP) 0224.
If the vehicle is in R (Reverse), D
(Drive) or M (Manual Mode), the
vehicle will shift to P (Park), the
ignition will turn off, and RAP will
remain active.
If the vehicle is in N (Neutral), the
ignition will return to ACC/
ACCESSORY and display the message

DRIVING AND OPERATING 221
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could change the
way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty. See
Add-On Electrical Equipment0280.
To start the vehicle: 1. With the Keyless Access system, the RKE transmitter must be in the
vehicle. Press ENGINE START/
STOP with the brake pedal applied.
When the engine begins cranking,
let go of the button. The idle speed
will go down as the engine warms
up. Do not race the engine
immediately after starting it. If the RKE transmitter is not in the
vehicle, if there is interference, or if
the RKE battery is low, a Driver
Information Center (DIC) message
will display. See
Remote Keyless
Entry (RKE) System Operation 07.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP 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 hold it there, then press
ENGINE START/STOP for up to a
maximum of 15 seconds. Wait at
least 15 seconds between each try,
to allow the cranking motor to cool
down. When the engine starts, let go of the button and 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
The Stop/Start system will shut off
the engine to help conserve fuel.
It has components designed for the
increased number of starts.
{Warning
The automatic engine Stop/Start
feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may restart
and move unexpectedly. Always
shift to P (Park), and then turn the
ignition off before exiting the
vehicle.

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 0288.
.Always dispose of engine oil
properly. See “What to Do with Used
Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick handle is a loop. See
Engine
Compartment Overview 0285 for the
location.

been off for at least two hours.
Checking the engine oil level on
steep grades or too soon after
engine shutoff can result in
incorrect readings. Accuracy
improves when checking a cold
engine prior to starting. Remove the
dipstick and check the level.
.If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is warm,
