before you can start the engine. Apply the brakes
before shifting into any driving gear.
KEYLESS ENTER ‘N GO™ — IGNITION
This feature allows the driver to operate the
ignition switch with the push of a button, as long as
the Remote Start/Keyless Enter ‘n Go™ key fob is
in the passenger compartment.
NORMAL STARTING
To Turn On The Engine Using The ENGINE START/
STOP Button

1. The transmission must be in PARK.

2

. P ress and hold the brake pedal while pushing
t
he ENGINE START/STOP button once.
3. The system takes over and attempts to start t
he vehicle. If the vehicle fails to start, the
starter will disengage automatically after
10 seconds.
4. I f you wish to stop the cranking of the engine
p
rior to the engine starting, push the ENGINE
START/STOP button again.
NOTE:
Normal starting of either a cold or a warm engine is
ob t
ained without pumping or pressing the accel -
erator pedal.
WARNING!
When exiting the vehicle, always make sure
the ignition is in OFF mode, remove the key
fob from the vehicle and lock the vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a

number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the transmission gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition (of a vehicle equipped
with Keyless Enter ‘n Go™) in the ACC or ON/
RUN mode. A child could operate power
windows, other controls, or move the vehicle.
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up
may cause serious injury or death.
CAUTION!
Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is above
idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
WARNING!

84 STARTING AND OPERATING
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect the
cord to a standard 110-115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
The engine block heater must be plugged in at
le

ast one hour to have an adequate warming effect
on the engine.
The engine block heater cord is routed under the
h ood

on the driver side of the vehicle. It has a
removable cap that is located near the air box.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the
drivetrain (engine, transmission, and rear axle) in
your new vehicle.
Drive moderately during the first 300 miles
( 5

00 km). After the initial 60 miles (100 km),
s p
eeds up to 50 or 55 mph (80 or 90 km/h) are
d e
sirable.
While cruising, brief full-throttle acceleration within
th
e limits of local traffic laws contributes to a good
break-in. However, wide-open throttle acceleration
in low gear can be detrimental and should be
avoided.
The engine oil, transmission fluid, and axle
l u

bricant installed at the factory are high-quality
and energy-conserving. Oil, fluid, and lubricant
changes should be consistent with anticipated
climate and conditions under which vehicle
operations will occur. For the recommended
viscosity and quality grades
Ú page 249.
NOTE:
A new engine may consume some oil during its first
f e
w thousand miles (kilometers) of operation. This should be considered a normal part of the break-in
and not interpreted as an indication of difficulty.
Please check your oil level with the engine oil indi
-
cator often during the break in period. Add oil as
r e

quired.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK position.
The foot operated parking brake is located below
th

e lower left corner of the instrument panel. To
apply the parking brake, firmly push the parking
brake pedal fully. To release the parking brake,
press the parking brake pedal a second time and
let your foot up as you feel the brake disengage.

Parking Brake

CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds before
t r

ying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.
