2013 MERCEDES-BENZ G-CLASS SUV tire pressure

There will be either no or only a weak course-
correcting brake application if:
R
there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
R a vehicle approaches you
too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate.
R a driving safety system intervenes, e.g.
ESP ®
.
R ESP ®
is switched off.
R the LOW RANGE off-road gear is activated.
R a loss of tire pressure has been detected.
Switching on Active Blind Spot Assist X
Make sure that active Blind Spot Assist
(Y page 218) is activated in the on-board
computer.
X Turn the SmartKey to position 2 in the
ignition lock.
Warning lamps 0043 in the exterior mirrors
light up red for approximately
1.5 seconds and then turn yellow.
Towing a trailer When you attach a trailer, make sure you have
correctly established the electrical
connection. This can be accomplished by
checking the trailer lighting.

Active Blind Spot
Assist is then deactivated. The indicator lamp
lights up yellow in the exterior mirrors and the Active Blind Spot Assist Currently
Unavailable See Operator's Manual
message appears in the multifunction
display.
HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R
when pulling away, especially on steep
slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is

canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
i Do not use the HOLD function when
driving off-road, on steep uphill or downhill
gradients or on slippery or loose surfaces.
The HOLD function cannot hold the vehicle
on such surfaces.
Activation conditions You can activate the HOLD function if:
R
the vehicle is stationary.
R the engine is running or it has been
switched off by the ECO start/stop
function (AMG vehicles).
R the engine is running.
R the driver's
door is

closed or your seat belt
is fastened.
R the transmission is in position D, R or N.
R DISTRONIC PLUS is deactivated.
Activating the HOLD function The vehicle's brakes are applied when the
HOLD function is activated. For this reason,
deactivate the HOLD
function

while in the car
wash or while towing. 192

R
The bumpers of your vehicle are not
suitable for installing detachable trailer
couplings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R If you do not
need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to
the ball coupling.
i When towing a trailer, set the tire
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y page 322).
You will find installation dimensions and loads
in the technical data (Y page 358).
The maximum permissible trailer drawbar
noseweight on the ball coupling for up to 3
persons is 562 lbs (255 kg). The maximum
permissible trailer drawbar noseweight for
more than 3 persons and the maximum load
in the trunk can be found in the trailer
drawbar noseweight table ( Y page 358).
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
or trailer identification plates. The lowest
weight applies.
i When towing a trailer, set the tire
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y page 322).
Please note that when towing a trailer,
PARKTRONIC ( Y page 194) and Blind Spot
Assist (Y page 186) are only available with
limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter
according to the load placed on the vehicle.
If necessary, use a trailer with a height-
adjustable drawbar. Driving tips X
On long and steep downhill gradients,
select shift range 1, 2

or 3 (Y page 150) in
good time.
i This also applies if you have activated
cruise control or SPEEDTRONIC.
X If necessary, shift the transfer case to LOW
RANGE(Y page 199).
This will use the braking effect of the
engine, so that less

braking will be required
to maintain the speed. which relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking,
depress the brake pedal repeatedly rather
than continuously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the
maximum permitted speed is. Observe the
legally prescribed maximum speed in the
relevant country.
For certain Mercedes-Benz vehicles, the
maximum permissible rear axle load is
increased when towing a trailer. Refer to the
"Technical data" section to find out whether
this applies to your vehicle. If you utilize any
of the added maximum rear axle load when
towing a trailer, the vehicle/trailer
combination may not exceed a maximum
speed of 60 mph (100 km/h) for reasons
concerning the operating permit. This also
applies in countries in which the permissible
maximum speed for vehicle/trailer
combinations is above 60 mph (100 km/h).
When towing a trailer,

your vehicle's handling
characteristics will be different in comparison
to when driving without a trailer and it will
consume more fuel.
On long and steep downhill gradients, you
must select shift range 1, 2 or 3 in good time.
i This also applies if you have activated
cruise control or DISTRONIC PLUS. Towing a trailer
