40 mph (64 km/h). For speeds at or exceed-
ing approximately 40 mph (64 km/h) the ESC
goes into "ESC Partial Off" When the vehicle
speed drops below 35 mph (56 km/h), the
ESC system goes back to "ESC Full Off". The
ESC is in "ESC Full Off" at low vehicle speeds
in 4L range so that it will not interfere with
off-road driving, but the ESC function returns
to provide the stability feature at speeds
above 40 mph (64 km/h). The “ESC OFF
Indicator Light” will always be illuminated in
4L range when ESC is in "ESC Full Off" or
"ESC Partial Off".
NOTE:
The “ESC OFF” message will display and an
audible chime will sound when the gear se-
lector is placed in the PARK position from
any other position, and then moved out of the
PARK position. This will occur even if the
message was previously cleared.
WARNING!
With the ESC in "ESC Full Off" mode, the
engine torque reduction and stability fea-
tures offered by ESC and ERM are dis-
WARNING!
abled. In an emergency evasive maneuver,
the ESC and ERM systems will not engage
to assist in maintaining stability. The "ESC
Full Off" mode is intended for off-road use
only.
2H Range (4WD Models) Or 2WD Models
ESC On
This is the normal operating mode for ESC in
2H range and on 2WD vehicles.
ESC Partial Off
When in "ESC Partial Off" mode, the TCS
portion of ESC (except for the limited slip
feature described in the TCS section), has
been disabled and the "ESC Off Indicator
Light" will be illuminated.
This mode is intended to be used if the
vehicle is in deep snow, sand, or gravel con-
ditions and more wheel spin than ESC would
normally allow is required to gain traction. To
turn ESC on again, momentarily push the
ESC OFF switch. This will restore the normal
"ESC On" mode of operation.NOTE:
To improve the vehicle’s traction when driving
with snow chains, or starting off in deep
snow, sand, or gravel, it may be desirable to
switch to the "ESC Partial Off" mode by
pushing the "ESC Full Off" switch. Once the
situation requiring ESC to be switched to the
"ESC Partial Off" mode is overcome, turn ESC
back on by momentarily pushing the "ESC
Full Off" switch. This may be done while the
vehicle is in motion.
The ESC will restore to normal ESC On mode
after each key on.
WARNING!
• When in “Partial Off” mode, the TCS
functionality of ESC, (except for the lim-
ited slip feature described in the TCS
section), has been disabled and the
“ESC Off Indicator Light” will be illumi-
nated. When in “Partial Off” mode, the
engine power reduction feature of TCS is
disabled, and the enhanced vehicle sta-
bility offered by the ESC system is re-
duced.
SAFETY

• Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s respon-
sibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the “Tire
Pressure Monitoring Telltale Light.”
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Base System
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the Receiver Module.NOTE:
It is particularly important for you to check
the tire pressure in all of your tires regularly
and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS)
consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in
the spare wheel if the vehicle is equipped
with a matching full size spare wheel and tire
assembly. The matching full size spare tire
can be used in place of any of the four road
tires. A low spare tire will not cause the “Tire
Pressure Monitoring Telltale Light” to illumi-
nate or the chime to sound while stowed in
the spare location.
The “Tire Pressure Monitoring Tell-
tale Light” will illuminate in the in-
strument cluster, a “LOW TIRE
PRESSURE” message will display in the in-
strument cluster, and an audible chime will
be activated when one or more of the four
active road tire pressures are low. Should thisoccur, you should stop as soon as possible,
check the inflation pressure of each tire on
your vehicle, and inflate each tire to the
vehicle's recommended cold placard pres-
sure value. The system will automatically
update and the “Tire Pressure Monitoring
Telltale Light” will extinguish once the up-
dated tire pressures have been received. The
vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) to
receive this information
The “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds, and will
remain on solid when a system fault is de-
tected. The system fault will also sound a
chime. If the ignition key is cycled, this
sequence will repeat, providing the system
fault still exists. The “Tire Pressure Monitor-
ing Telltale Light” will turn off when the fault
condition no longer exists. A system fault can
occur by any of the following scenarios:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same
Radio Frequencies as the TPM sensors.
79

2. Installing some form of aftermarket win-
dow tinting that affects radio wave
signals.
3. Lots of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with
TPM sensors.
Vehicles not equipped with instrument clus-
ter display will inform the driver which tire(s)
are low but not provide actual tire pressure.
The low tire ISO telltale will illuminate along
with “LoTIrE” message displayed in the ODO
and then it will scroll to which tire location is
lower than the Placard Value.
Tire location will be displayed as follows:
LF =LeftFront
rF =rightFront
Lr =Leftrear
rr =rightrearNOTE:
• If your vehicle is equipped with a matching
full-size spare wheel and tire assembly, it
has a tire pressure monitoring sensor, and
can be monitored by the Tire Pressure
Monitoring System (TPMS) when swapped
with a low pressure road tire. In the event
that the matching full-size spare tire is
swapped with a low pressure road tire, the
next ignition key cycle will still show the
“Tire Pressure Monitoring Telltale Light” to
be ON, and a chime to sound. Driving the
vehicle for up to 10 minutes above 15 mph
(24 km/h) will turn OFF the “Tire Pressure
Monitoring Telltale Light” as long as none
of the road tires are below the low pressure
warning threshold.
• If your vehicle is not equipped with a
matching full-size spare wheel and tire as-
sembly, it does not have a tire pressure
monitoring sensor in the spare tire. The
TPMS will not be able to monitor the tire
pressure. If you install the spare tire in
place of a road tire that has a pressure
below the low-pressure warning limit, upon
the next ignition key cycle, a chime will
sound and the “Tire Pressure MonitoringTelltale Light” will turn ON. After driving
the vehicle for up to 10 minutes above
15 mph (24 km/h), the “Tire Pressure
Monitoring Telltale Light” will flash on and
off for 75 seconds and then remain on
solid. For each subsequent ignition key
cycle, a chime will sound and the “Tire
Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then
remain on solid. Once you repair or replace
the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS
will update automatically and the “Tire
Pressure Monitoring Telltale Light” will
turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any
of the four active road tires. The vehicle
may need to be driven for up to 10 minutes
above 15 mph (24 km/h) in order for the
TPMS to receive this information.
Premium System — If Equipped
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the Receiver Module.

Seat Belts For Older Children
Children over 1.50 m in height can wear seat
belts instead of using child restraints.
Use this simple 5-step test to decide whether
the seat belt properly fits the child or if they
should still use a Group 2 or Group 3 child
restraint to improve the fit of the seat belt:
1. Can the child sit all the way back against
the back of the vehicle seat?
2. Do the child’s knees bend comfortably
over the front of the vehicle seat – while
they are still sitting all the way back?
3. Does the shoulder belt cross the child’s
shoulder between their neck and arm?
4. Is the lap part of the belt as low as
possible, touching the child’s thighs and
not their stomach?
5. Can the child stay seated like this for the
whole trip?
If the answer to any of these questions was
“no,” then the child still needs to use a Group
2 or 3 child restraint in this vehicle. If the
child is using the lap/shoulder belt, check
belt fit periodically and make sure the seat

To Install An ISOFIX Child Restraint
If the selected seating position has a Switch-
able Automatic Locking Retractor (ALR) seat
belt, stow the seat belt, following the instruc-tions below. See the section “Installing Child
Restraints Using the Vehicle Seat Belt” to
check what type of seat belt each seating
position has.
1. Loosen the adjusters on the lower connec-
tors and on the tether strap of the child
seat so that you can more easily attach the
connectors to the vehicle anchorages.
2. Place the child seat between the lower
anchorages for that seating position. For
some second row seats, you may need to
recline the seat and / or raise the head
restraint to get a better fit. If the rear seat

WARNING!
• ONLY use the driver’s side floor mat on
the driver’s side floor area. To check for
interference, with the vehicle properly
parked with the engine off, fully depress
the accelerator, the brake, and the
clutch pedal (if present) to check for
interference. If your floor mat interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
• ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area
when the vehicle is moving. Objects can
become trapped under accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
• NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference
WARNING!
with the accelerator, brake, or clutch
pedals.
• If the vehicle carpet has been removed
and re-installed, always properly attach
carpet to the floor and check the floor
mat fasteners are secure to the vehicle
carpet. Fully depress each pedal to
check for interference with the accelera-
tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in thetread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected imme-
diately.
